Passage 1
ta
fa
1. B
The subject of the rhetorical purpose. Ask the author what he meant
by using the term "an in the circle" when talking about Jess's family
standing in a circle.
us
A） The family lost their way after just completing a very difficult
journey. Error, the article does not express the meaning of a family
after a hard trip are very tired.
rM
B） The family was a little anxious and hesitant about interacting.
（
A
m
That's right, because the family is worried about whether the little
girl will get along with her grandfather the first time she sees her
grandfather, and the other is that family members from Nigeria and
the United Kingdom don't know each other very well and are a little
hesitant about interacting with each other.
In this option self-conscious It means "being upset because you
care
what
other
people
think
of
themselves."”
nervous or uncomfortable because
you
are worried about
r.
what people think about you or your actions）。
M
Example.：He looked uncomfortable, like a self-conscious adolescent.
He looked uncomfortable, like a restless teenager.
Tentative means "tentative, hesitant" (done without confidence;
hesitant)
Example.：He eventually tried a few tentative steps round his hospital
room.
He finally took a tentative few steps around the ward.
C） openly suspicious of each other's motives. This means that the
family is suspicious of each other, obviously wrong.
D） Rely on each other to dispel doubts. The article does not say that
family members need to rely on each other, but rather that family
members from Nigeria and the UK do not know each other well until
they need other family members to give them. So D is wrong.
us
ta
fa
2. D
Details. Which factor, I ask, was decisive in Jess's reaction to meeting
his grandfather?
The evidence, in lines 3 to 6, shows that when Jess's mother
previously described his grandfather to Jess, the grandfather's image
was not a mellow person, and it was possible that the child was shout.
Mellow means "soft; gentle"(smooth and soft,or not too sharp,
bright,new, or rough). Jess was therefore more afraid of meeting his
grandfather. Her reaction was influenced by what her mother had said
to her before. So choose D. Because the grandfather's actual image is
Mellower and Smaller's, the intimidating error of option A.
rM
3. B
The question of seeking proof. Ask the evidence of the answer to the
last question, see the analysis of the last question.
A
m
4. D
Details. Ask the article about some of Jess's father's actions.
According to lines 51 to 57 of the article, Jess's father took the
initiative to throw Jess into her grandfather's arms and went upstairs
on his own, in order to give Jess and Grandpa a chance to be alone,
so he chose D.
r.
5. D
When Jess was asked what her first reaction was when her
grandfather called her "Wuraola"?
M
A） She hated the fact that people on her Nigerian side insisted on
using the name "Wuraola".
B） She remembered the name, but doesn't remember its exact
meaning.
C） She was frightened that her grandfather remembered the name.
D） She knew it was its name, but couldn't admit it.
According to lines 21 to 26, Jess knows the name, but doesn't know
what to say or do. So select the D option.
6. A
Separate proof-seeking questions. Which option does it suggest that
Jess is familiar with some of the customs that her mother's family honors?
On lines 22 to 25, Jess knew that the name Wuraola was her
grandfather's letter asking her mother to give her the name of the
Nigerian-style name-calling ceremony, indicating that Jess had some
knowledge of the Nigerian-style name-calling ceremony.
ta
fa
7. B
The subject of the rhetorical purpose. What is the purpose of the
description of lines 32 to 37?
A） Emphasize that Jess is mediting on some philosophy through a
us
natural scene. Philosophical meditation refers to thinking about the
important problems such as man's own existence and the purpose
of life. Jess is only a little familiar and unfamiliar with the name
Wuraola, rather than philosophically thinking about his existence.
So A is wrong.
rM
B） Suggests that Jess's physical situation is consistent with her
A
m
emotional state. It is important to note here that the term "physical
situation" in this option is that lines 34 to 35 "clothes stick to her
like another layer of skin" and "emotional state" means that the
name "Wuraola" on line 36 is like another person's name." Jess
feels that the name Wuraola is like a layer of clothes that are too
close to her skin, and she doesn't want to admit that the dress is
already another layer of her skin, but it does stick very close, like
skin.
C） Describe jess's thoughts about her own Nigerian background
r.
through a nostalgic filter. The article doesn't show that Jess misses
his hometown. So C is wrong.
M
D） Reveal Jess's acceptance of his new life by describing an ordinary
event. This passage doesn't tell a story, nor does it reveal that Jess
was so quick to embrace his new life. And, as can be seen from this
description, don't say about the new life, even with the name
Wuraola, she is still a little not used to. So D error.
8. C
The subject of the rhetorical purpose. A few questions in lines 38 to 42
are mainly about how Jess is described.
The 38The key words from line 42 are the identity（The.39），identity
The definition in the dictionary is “the fact of being who or what a
person or thing is”，Corresponds to the correct option C a new sense
of who she is。
ta
fa
9. A
Details. Ask Jess what's the difference between meeting his
grandfather for the second time and the first time?
According to lines 49 to 57 of the article, Jess's mother and aunt left,
and her father went upstairs, when there were no other family
members around.
Passage 2

10. C
Vocabulary questions. Crisp retouched the lines of the shirt in
thearticle, so it means"smoothly and attractively stiff" (paperor cloth),
while sharp also has the meaning of (cloth or their wearer) smart and
stylish, both meanings are similar.
A
m
11. B
The main topic. Requires abstract generalization of the full text
structure. Option A is wrong in the article not only about one
experiment, but about two studies. Option C is wrong in not
contrasting two examples, and in the end there is no revision. Option
D is wrong in the article and does not mention criticism of the theory
and rebuttal of criticism.
M
r.
12. D
Infer the question. If another scientist claims that "body-action
cognition" (where embody is difficult to translate, only translated into
"body-moving" barely enough) theory doesn't apply when people
think of abstract words like "peace" and "honesty". This means that
when people think of "sitting on the couch", "frying pan" (the items
that appeared in the first experiment), and "tetris" objects (a word that
many dictionaries do not have, the actual meaning is that we play
russian squares as children), they do rely on touch, smell and other
physical actual feelings of the movement has always thought of these
concepts, but when thinking of the words "peace", "honesty", you can
not think of such concepts according to the actual feelings of the
body's movements. Q. How would the author of this article respond to
the scientist's claim?
A
m
rM
us
ta
fa
Option A: The author would argue against the scientist, saying he
didn't fully understand the theory of "body-acting cognition." The
scientist's questioning is justified, and there is no evidence that the
author would baselessly say that people's consideration of the theory
of "body movement cognition" is incomplete.
Option B: The author will insist that people think more of concrete
objects and less of abstract concepts. (Such a statement is actually an
escape from a positive response to the scientist's questioning.) There
is no place in the article to suggest that the author thinks that "people
don't think much about abstract concepts", so B is wrong.
Option C: The authors suggest that the theory of "body-acting
cognition" should be tested under different experimental conditions.
The article does not mention that the author thinks that the
experimental condition of the theory of "body action cognition" is too
single, and needs to do several different experimental conditions. The
single thing is that the objects used in the experiment are concrete
things, not abstract concepts. So C is wrong.
Option D: The author will (reluctantly) admit that the theory of "bodymoving cognition" does not really apply in all cases where one wants
to do all kinds of things. Because the article mentioned two
experiments, one is to take the "frying pan" to do experiments, the
other is to take the "Russian block" object to do experiments, are
actual objects, there is really no "abstract concept", so admit that the
scientist raised a reasonable question, is the author's rational
response. Option D is correct.
M
r.
13. C
Details. According to the definition of the theory of "body-acting
cognition" in lines 13 to 16, this theory refers to the pattern of activity
in the brain that occurs when one thinks about something or
recognizes an object, which is the pattern of activity of the brain
responsible for the area of the touch or taste when one touches
something and smells something. This simulation emits the same
actions that make the body tactile and taste-like. So the key word for
the C and C options is the last word "body". The word embody in "body
action cognition" does not mean "embodiment"as we often say, but
actually refers to the bodyizationof cognition (a spirit) with a physical
form.
Originally people think of a thing (cognitive a thing), it is reasonable to
say that as long as you think about it, should not send out body
movements, and "body movement cognition" that people think of a
thing, the body will send a signal to touch this thing or smell this thing.
Option A's powerful events, Option B's improve, are all not mentioned
in the original text. Option D alone is not a problem, but it is not part
of the "meltd cognition" theory asked by the topic.

16. A
Details. The evidence was in lines 35 to 40, and the scientists were not
secretly concerned about the focus of the experiment they told the
subjects, so the subjects didn't know what the real focus of the
experiment was.

The question of seeking proof. Ask the evidence of the answer to the

18. C
Infer the question. The subjects who were likely to take part in Tucker
and Ellis's experiments all wrote with their right hands, i.e. they were
all right-handed, and asked if that was the case, could tucker and Ellis'
conclusions be challenged? This is actually what we often call the
"weakening question", that is, if something is true, can we weaken the
conclusion?
According to lines 49 to 53 of the article, being faster or more accurate
with one hand than the other means that the person is left-handed or
right-handed. The experiment changed all objects in the opposite
direction, in order to exclude the possibility that people are left-handed
or right-handed and affect the results of the experiment.
19. D
The question of seeking proof. Ask the evidence of the answer to the
last question, see the analysis of the last question.
20. D
Chart questions.
A) Because the combination of left handle and left hand in the figure
corresponds to 628.2, not the slowest. So A is wrong.
B) Because the combination of right handle and right hand in the figure
corresponds to 627.3, not the slowest. So B is wrong.
C) Because the combination of the left-hand and right handle in the
figure corresponds to 639.8, the combination of the right-hand and left
handle corresponds to 639.8, which is not the fastest, so C error.
D) Because the left-hand handle and right-hand handle and right
handle in the figure are indeed the fastest, D is correct.
Passage 3

fa
21. C
A comprehensive analysis of the picture. Ask a person who agrees
with the theory of "body-acting cognition" to interpret the data in the
table in this way?
According to lines 44 to 47 of the article, when the handle on the frying
pan was on the left, the responses wereing the left hand were were
faster than those involving the right. If the handle of the frying pan was
in the same direction as the subject's hand, the subjects would react
more quickly. Conversely, if the handle of the frying pan and the hand
used are in the opposite direction, the brain will react more slowly. So
option C is correct.
A

22. B
Analogy question. Ask which situation is similar to the "trade-off"
mentioned in the article: frogs have to do a trade-off to grow faster and
live in more dangerous environments. Note that here trade-off means
a situation in which you accept accept bad in

good
Example.：For some car buyers, lack of space is an acceptable trade-

off for a sporty design.
For some car buyers, it is acceptable to design a sports car-style
model with even a small space.
So pick B, the deer for more resources (i.e., the interpretation of in
order to have something good), rather than close to the predator (i.e.,
the definition of the accept something bad).
23. C
Details. Ask some amphibians what good it is for them to dig holes in
the mud.
According to lines 14 to 17, digging holes, laying eggs in wood or
holes, producing natural sunscreens in the body, and so on, are all for
defend against UVB radiation, and digging holes is by limiting your
exposure to the sun. So pick C.
24. D
Details. Q Which of the following conclusions can be inferred from the
research conducted at Fresh Alps?
A） Altitude affects the growth and development of radon. According
to the article, it is UVB that will affect the growth of radon. High
altitude alone, no. So A is wrong.
B） No matter how high the altitude, high-intensity exposure to UVB
ta
fa
can have a fatal effect. According to lines 41 to 42 of the article, the
effect of UVB in some cases is not lethal, but sublethal (slightly less
lethal) or subtle (slightly harmful). So B is wrong.
C） The concentration of DNA photolyase in the frogs studied (i.e.,
us
those living in French Alps) was inherently higher. According to
lines 57 and 70 to 74, the concentration of DNA photolyase in this
frog is not relatively high and has not been confirmed.
rM
D） Different individuals of the same species of frog have different
endurability to UVB exposure. According to lines 49 to 54 of the
article, frogs that live at high altitudes receive less DNA damage
than their species that live at lower altitudes. So C is right.

Vocabulary questions. Experience means "experience, encounter

Experience means "suffer; suffer; endure", experience or subjected to

two words is close.
27. A
Details. Q What would happen to the Pacific tree frog if further
research proved that it was indeed the DNA in its body that protected
people living at high altitudes from BAP?
According to lines 64 to 70 of the article, BaP and UVB destroy DNA in
the same way, and also by curling the DNA spiral to destroy the DNA.
In the case of BaP injuries, Alps frogs living at high altitudes suffer
less DNA damage than Alps frogs living at low altitudes. And because,
according to lines 34 to 39 of the article, Pacific tree frogs (which have
been shown to be the most concentrated frogs in the body for DNA
photolyase) are the least afraid of UVBs. Because UVB and BaP
destroy DNA in the same way, it can be inferred that since the Pacific
tree frog is not afraid of UVB, then it is not afraid of BaP. So choose A.

Chart questions.
A) Spawning in the place of no exposure only if the photolyase activity
value is small and equal to 0.7. The word options are correct.
B) All photolyase activity values greater than 3.5 are spawned at the
place of high exposure. We see that Rana aurora in the table
corresponds to a photolyase activity value of 6.1, greater than 3.5, but
corresponding to avariable, not high exposure, so B is wrong.
C) Only the photolyase activity value is greater than or equal to 7.5 to
lay eggs in the variable exposure, we still see that the Rana aurora in
the table corresponds to the photolyase activity value is 6.1, less than
7.5, but the corresponding is also the variable exposure, so C is wrong.
D) All photolyase activity values greater than or equal to 1.0 are
spawned at open water. We see that Rana aurora in the table
corresponds to a photolyase activity value of 6.1, greater than 1.0, but
corresponding to stem, not open water. Hyla cadaverina, too, has a
photolyase activity value of 3.5, which is also greater than 1.0, but
corresponds to the atached to debris near surface, not open super
water.
31. C
Chart questions. According to the chart, the frog species found to
correspond to high exposure is Hyla regilla.
32. C
A comprehensive analysis of the picture. Which of the information
shown in Figure 2 does not match the researchers' comments about
frog populations living in Fresh Alps?
A） Frogs living at an altitude of 800 metres without UVB exposure
suffer less DNA damage than frogs living at an altitude of 450
metres. Since the article does not mention the damage to frog DNA
at different altitudes without UVB exposure, we cannot say that the
information shown in the chart contradicts the article.
B） Frogs living at an altitude of 410 metres without UVB exposure
ta
fa
suffer less DNA damage than frogs living at 450 metres above sea
level. Because the article mentions UVB exposure as one of the
causes of DNA damage, frogs at the same altitude must be less
damaged than UVB exposure. So it matches the article information.
C） Frogs living at an altitude of 800 metres with UVB exposure suffer
rM
us
more DNA damage than frogs living at 249 metres above sea level.
According to lines 49 to 54 of the article, frogs that live at higher
altitudes should suffer less DNA damage. So the chart doesn't
match the article. This option is correct.
D） Frogs living at an altitude of 450 metres with UVB exposure
A
m
suffered more DNA damage than frogs living at an altitude of 2,450
metres without UVB exposure. Also according to lines 49 to 54 of
the article, frogs that live at higher altitudes should suffer less DNA
damage. So the 2450-meter frog suffered less DNA damage than
the 450-meter frog, so the information for this option is consistent
with the article. So this option is wrong.
r.
Passage 4
M
33. A
The main topic. Ask how the veins of the full text are shifted. The first
natural paragraph of the article (lines 1 to 14) is about the difficulties
facing the United States, such as debt and national instability, and the
second natural paragraph (lines 15 to 24) is about whether the United
States can build a strengthened federation and government imagined
by republican theorists and the American people. Starting with line 25,
talk about the limitations of American political understanding, the
transition to some of the consequences of a human weakness (i.e.,
people may re-opt for slavery by authoritarian governments, etc.).
Matches option A. Note that the word repercussion in option A is
difficult, it means"(especially unwelcome) consequences;impact", an
unintended consequences of the event some time ”，after an event or
action, especially an unwelcome one.
34. B
The subject of the rhetorical purpose. What is the purpose of the
article using the term "child just learning to walk"?
A） The U.S. decision to pursue independence from the U.S. is
childish and immature (note that juvenile means childish;
immature). This is to say that the author thinks that the decision of
American independence is wrong. This is clearly not true.
ta
fa
B） Emphasize that Americans have no experience with their new
rM
us
political stance. According to lines 9 to 14 of the article, American
independence is a new kind of political position for Americans,
Americans have encountered a lot of difficulties, so this new politic
position is a difficult road, Americans do not know how to take the
road, no experience. The key is to understand the word navigate,
where the navigate is a and object verb, followed directly by the
guest language, which means "(difficultly) walk by, through"make,"
one's way with difficulty over (a route or terrain). Example: The
drivers skillfully navigated a twisting and muddy course
The drivers skillfully struggled through the tortuous muddy road.
C） It's naive to admit that Americans believe in an equal society. The

Americans doubt themselves after gaining independence.???

A） Will it be forced to rejoin the UK to ensure future financial security?
The article does not mention that Americans would propose such
a quest.
B） Whether you can return to your old job. The article does not
mention that Americans would propose such a quest.
C） Is it possible to create a political system that appeases all citizens?
According to lines 16 to 24, the it was specify corresponds to the
"Americans in the quest" in the header, how the states be
tranquillized and most of the people of the United States

Infer the question. Ask Warren, the author of the article, what do you
think of the characteristics of Americans in the post-independence
revolution?
According to lines 33 to 35, the author argues that the American
thought (suppose is a derogatory "think" that can be translated as
"think") as long as it was enough to get rid of the British occupation
and not to have a king in the United States (i.e., not to engage in the
monarchy), and that nothing needed to be done. In fact, "breaking" is
easy, "building" is difficult. The American idea is too naive. In fact, then
to line 36 to line 44, the author continued to say they were not generally
sly sly... They were not sly, you can see that the author is doing a
negative evaluation, because C and D are positive reviews, can first be

Which sentence does it prove that after the war, Americans want a

43. B
The subject of the rhetorical purpose. Ask what is an important feature
of the first natural segment?
A） Some
of
the
pre-assumptions
influenced
the
theoretical
r.
assumptions put forward by Ripple and his colleagues. An
important feature of the first natural segment is that the author
wants to insist on how powerful and important these presets are.
First, the inform in option A means "influence someone's attitude
or opinion" to influence someone's attitude or opinion.
M
Example.：Her experience as a refugee informs the content of her
latest novel.
Second, Ripple and his colleagues put forward the theory that the
re-addition of wolves, the chain reaction to the wolf-coyote-rabbit
food chain, is achieved mainly through two mechanisms: First, the
increase in wolves will reduce the number of coyotes, which is
good for the coyotes. Second, the increase in wolves will make deer
do not dare to bow their heads to eat grass, which will improve the
living environment of rabbits, and thus the rabbit-eating slugs.
Again, let's look at what the first paragraph is about. Changes in
the number of animals (like wolves) at the top of the food chain
ta
fa
affect the relationship between animals lower in the food chain,
such as dragonflies and rabbits. The re-addition of wolves has a
knock-on effect on the food chain of wolves-coyotes-rabbits, which
may be beneficial to the protection of slugs.
These two assumptions do influence Ripple's theory.
But the first natural paragraph doesn't insist on how powerful or
important the two subsumptions are. The first natural paragraph
deals with the reality of the ecological environment in the two
states bordering Canada and the United States (which Ripple and
his colleagues are working on), and many wolves migrate south
from Canada to Idaho and Washionton, where Washington has few
rabbits and moths and more coyotes. So B is correct, A is wrong.
In addition, the function of the first paragraph is not to talk about
concepts, nor is it to compare the differences in animal habits. So
C and D are wrong.

second article about the mortality rate of coyotes in northwest
Montana?
First found the article refers to the 68th to 71st lines of the mortality,
which says that coyotes are mainly killed by courgar, and coyotes feed
mainly on wolves. The implication is that, at least in northwest
Montana, the increase or decrease in the number of wolves will not
actually have a significant impact on coyotes. So choose D.

animals are preyed upon by coyotes and dragonflies. Only in this case
do coyotes and lynx form the relationship between the company (lines
77 to 78).

Two relationship questions. The second article challenges some
aspects of the theory of the first article, such as the fact that coyotes
may have rebounded, that the relationship between wolves and
coyotes does not apply everywhere, and that coyotes and coyotes are
not simply coyotes. So A is right. The second article did not question
the authenticity of the data in the first article, so B was wrong. Nor is
it argued that the assumptions put forward in the first article need to
be corrected, so C is wrong. There was also no discussion of a study
to test the theory (local) presented in the first article. The research
mentioned in the second article was not done to test the theory of the
first article, but rather to raise doubts and possibilities, rather than to
talk about specific studies. So D error.
50. B
Two relationship questions. Ask about wolves and coyotes, which one
will both articles agree with?
A） In the ecosystem, wolves and coyotes are generally at the same
level (location) of the food chain. The first article clearly suggests
that coyotes are at the next level of wolves. So the author of the
first article wouldn't agree. So A is wrong.
B） It is possible for wolves to have a chain reaction throughout the
food chain by affecting coyotes. This is the central argument of the
first article, and the first sentence of the second article (lines 48 to
52) endorses it, mainly the first line of correctly, expressing the
author's positive attitude towards this argument. So B is right.
C） In some cases, the presence of wolves can be beneficial to
coyotes. The first article obviously thought that wolves eat coyotes,
so the authors of the first article would not agree. So C is wrong.
D） Wolves and coyotes have an ecological impact on large
ta
fa
herbivores (deer, moose, etc.) (reducing deer) and behavioral
effects (making deer less likely to bow their heads and eat grass).
Coyotes have little effect on large herbivores because the article
mentions that they feed on large herbivores and coyotes do not
feed on large herbivores. So D error.

51. D
Two relationship questions. What about the second article's statement
on lines 28 to 31 of the first article, "Because coyotes prey on coyotes,
the increase in wolves leads to fewer coyotes, which will relieve the
pressure on coyotes to prey on coyotes"?
According to the 85 to 88 lines of the second article, the authors of the
second article argue that "the mere discovery of a small cocoon being
killed by a coyote does not prove the relationship between the food
chain in which coyotes prey on the cocoon." "The idea is that the
author thinks that we should see a large number of coyotes killed by
coyotes in order to prove that coyotes in the upper level of the coyotes,
coyotes and coyotes are one to eat another relationship. So choose D,
there is only one objectation, it belongs to insufficient data.

Add or subtract sentence questions. No, because the upper and lower
sentences are talking about Nicodemus this town, although this town in
Kansas state, but the upper and lower sentences just say this town, not
to say the whole state, so should not add a whole Kansas state at a
certain time how many people come in, the overall number of people
into the state and the number of people into this town is not necessarily
related. So it shouldn't be in the context of a separate discussion of

Word meaning analysis, this question is more difficult. It's easier to
drain thespread, spreading this meaning completely can't be put into
the original text. Let's put out the English explanation of collins in the
remaining three words (Oxford, as does Webster's interpretation).
expanse: An expanse of what, usually sea, sky, or land, is a large
amount of it. It can be seen that its characteristics are large, then it does
not conform to the original text, which is that some people go back to
their familiar place (home) and do not want to emphasize that
everyone's hometown is very large.
locale: A locale is a small area, for example, the place where something
whats or where action of a book or film is Set. It can be seen that the
word emphasizes that something has happened in this place, and the
original text just wants to say that some people have returned to their
hometown and there is no evidence that something has happened in
their hometown, and that there is an adjective, familiar, which is even
more proof that the author wants to emphasize that people in this place
us
ta
fa
are familiar with it and do not want to emphasize that something
happened in this place, so it cannot be used to refer to people's
hometown.
terrain: Terrain is used to refer to an area of land or a type of of land of
when you are considering its physical When it can be seen that Terrain
is used to describe the terrain of a place, the original text says that
people go back to a familiar place, then this familiar actually contains
people's familiarity with the local natural environment (and of course,
familiarity with the local people), so you can use terrain.
7. D
Punctuation. When connecting two sentences, colons and buts cannot
be used at the same time, and stop marks and buts cannot be used at
the same time, so A and C are excluded. The part of the include is an
insertion, so there must be a comma before and after, so discharge B.
Things that meet the punctuation requirements D, with comma plus but
to connect the front and back two sentences, the second sentence has
the including part as the insertion, before and after the comma, correct.

Logical words. The last sentence says that the abundance of people's
lives depends on the amount of land produced. The next sentence is
that the harvest of the land has increased and people can buy wood to
build houses. The front and back two sentences can be connected by
the word "final". Other options, still translated as "but", rather
translated as "but", next translated as "next" into the sentence do not
work well together. Note that next does not work, because there are no
further steps, so this sentence here will be followed by "last". The
premise of next is that there will be another word to say about the finale,
but not here.

Add or subtract sentences. This sentence gives people specific means,
that is, from where to find evidence that dodo is not really so stupid, so
this information is very important, in order to draw the following "dodo

choose B, because there is no content of the previous sentence of

it is placed in front of the fourth sentence and then after the third
sentence.

Word meaning analysis, this question is more difficult. The students'
main tangles are in the C and D options.
M
satisfactory ： good enough for a particular purpose （ Near-meaning
words acceptable）
gratifying：pleasing and giving satisfaction
From the English interpretation given by the Oxford Dictionary, it can
be seen that it is poor, that is, although satisfied but not particularly
excellent meaning, but also for a particular need of satisfaction, but
gratifying is to make people happy, satisfactory, not for a particular
purpose, the focus is not on the "enough" problem, but on whether to
make the other side happy. In this question, the context doesn't want to
emphasize that the job is pleasing to those who help others (not to say
that it's not bad for a person's needs, it's bad, it's unsatisfactory, it's
barely enough to meet people's needs).
ta
fa
27. C
Logical words. The whole paragraph is a total score structure, the first
sentence is the point of view, said that although the job is low salary,
but other aspects of the return is high. Let's start by specifying which
areas of high returns are high, one is that for those who help others, the
job makes them happy, and the other is that the responsibility of the job
is also significant. So before and after is the logical relationship of
what's more.

28. C
Before and after are two sentences, commas can not be connected to a
sentence, excluding AB, D colon misplaced and the logical relationship

34. B
The Granting part of A is not a complete sentence so you can't use a
period, and the comma in C is wrong because the comma can't connect
two sentences. The form of the and front and rear verbs in D is not
correct, because it cannot be connected with and, therefore, only B can
be selected, with a comma and then granting belongs to the structure
of the accompanying adverb.

United Kingdom.

A's logic is not right, not to replace opting, but precisely to choose to
use a instead approach, corresponding to D. B's logic is correct, but it's
not as simple as D's. C's fixed language from the West is not correct,

against him. In his speech, Roosevelt proposed theGood Neighbor Policy,also
known as the Good Neighbor Policy.
Roosevelt's "Good Neighbors Policy" speech,
and presented English-Chinese documentation of the three speeches. The third
Roosevelt speech we gave was not the same as the one in the exam, but the content
was much the same. I do not know if there are students seriously looked, if you look,
should certainly be able to more easily cope with this examination of the "good
neighbors" bar.
Passage 3 Natural Sciences

information is large and complicated, and the overall difficulty is greater. The article

invisible to each other, it is necessary to send a message to its companions by

a little more or the D-tone is a little more. The scientists then used models of

Models of some natural enemies (Chinese called "specimens") to scare Chickadee,，

Then analyze and then analyzed chickadee's tone. Starting with line 42, The line

included The study included a set of two experiments, the first of which was in
several different sizes a set of two experiments, the first of which used several model

Chickadee emits fewer predator Ds when
r.
itencounters a larger predator model that is not a threat. Then do a second
M
experiment, this time not to show Chickadee, the Predator model, but to scare them
in a different way. It's about putting the recording from the first experiment back to
Chickadee to see how Chickadee reacts. "The results showed that chickadeeinitiated mobbing (gathering will initiate to harass and besiege predators) when it
heard a recording of a cry with more D tones." This second experiment linked the Dto-mobbing D Harmonic. mobbing behavior. This means that Chickadee does
convey different messages through the tone of the call.
Question 28 examines the purpose of the experiment, and question 30 requires a
certain degree of difficulty in combination with graph reasoning.
Passage 4 Social Sciences (Behavioral Sciences).
The article language is not difficult, there is no complex concept, the experimental
design is very good to understand, that is, let people take a hot drink or cold drink
for a time, and then let people say that they feel for a stranger or acquaintance, found

common in the SAT exam and has some difficulty.
rM
The amount of information in the article is large and difficult. The article is about an
experimental field in Jena, This place has an experimental field from Germany, that
has been in place for many years since 2002, so we know that a variety of crop
A
m
hybrids can increase soil microbial activity, and that some bacteria can help plants
fight disease. Scientists also wanted to know more about how a variety of crops mix
and how to mix and match different crops, so they first wanted to find out by
studying bacteria in the soil. But when it was later discovered that bacteria in the
soil had moved to mediums for study, bacteria were prone to survival, and
r.
sometimes two plants added a bacterium to the soil, so even finding the bacteria
M
would not indicate which plant contributed more to soil improvement. So Jousset
and Latz began looking for DNA in the soil bacteria. The microbial structure of the
soil can be identified by comparing which disease-resistant DNA existsin mixed
soils with different matching proportions, or it can focus on bacteria that inhibit
pathogens (rather than all the beneficialbacteria in the soil).
Passage 1
1. A

Thornton Madame would like to go to a few people's homes as guests, and then

two articles use writing?
A) The first article analyses some historical data on a number of countries in the
Americas, while the second article mainly expresses the views of those
countries in the first article. The first article is not analyzing historical data, so A
is wrong.
B) The first article advocated broad changes in political activity, while the second
article defended the status quo and argued that it should be maintained. The first
article did not say that the status quo was bad and that there should be a big
ta

change, but rather a greater emphasis on mutual respect and equality within the
Americas on the basis of Monroeism, and finally, although there were calls for
the removal of trade barriers, it did not call for broad changes. The second article
is not to say that the status quo is good, to maintain the status quo, but to point

out that the status quo is not as ideal as the first article said. So B is wrong.
C) The first article set out the goals that countries in the Western Hemisphere

threat.
A) Make sure that the will not change the composition of the tone in the call
without a direct threat. Wrong, because this option means that the second
experiment is to see what kind of callthe would make without predator and only
with a recording. The purpose of the second experiment was to observe the
behavior of the without recording the calls made by the again.
B) Clarify whether the size of the predator model affects the patterns (i.e. the
composition) of the various tones in the tits' call. The first experiment, perched-

A)Many of the subjects, who held a hot drink for a moment and then remembered
to fight intimacy, were people who had known each other for a relatively short
time. If this is true, then it is equivalent to holding the hot drink, to the uncooked
people score intimacy, all hit a high score, indicating that hot drinks do have a
great impact on people's judgment.

B)Many of the subjects, first holding a cold drink for a moment, and then
remember that the person who fights intimacy is a less familiar person. If this is
true, then it is equivalent to holding a cold drink, to the less familiar people hit
us
the intimate score, hit a lower percentage, it may be because they do and think
of the person is not too familiar, that is, even if not first hold a cool drink, will
score lower. This suggests that people's judgment may not be influenced by cold
rM
drinks, which contradicts the experimental conclusions in the article (that people
are affected by the cold heat of the drink they hold first), which weakens the
conclusions of the experiment. So option B is correct.

WRITING
Passage 1
1. . C
Transition sentence. The first sentence said CP is very strong, the last
sentence said CP always feel that they do not do well, so before and after
ta
fa
the need for a transition sentence with a turning function. Option C means
exactly "but, at the time, he was not satisfied with his work".
2. . A
us
From upon to Germany is the adverb of the whole sentence, after which
a comma is required to take over the main sentence, and Cologne and
Germany are small administrative places to the relationship between the

large administrative places that contain it (similar to Beijing, China), so to
hit a comma between the two.
3. . B
A

As soon as Plank heard that Duke Ellington was coming to Cologne, he

so Duke
Ellington should be very attractive to Plank, so here's why. Option B says
Duke Ellington is a renowned
performer, which explains why Cologne
session.
r.
immediately thought about going to the
M
4. D
The principle of simplicity. A's emphasize and highlight repeat, B-option's
elements and dashed parts are repeated behind the aspects, C-option's
unique and particular repeat.
5. C
The context is talking about Plank and Ellington's recording session,
while the sentences waiting to be added are introducing Trombones and
saxophones, which have nothing to do with the topic of context
discussion, so choose C.
6. D
Selecting A results inrun-onon sentence. B is followed by a fixed clause,
and the main sentence cannot be connected with a half sign, so B is
wrong. C with which to decorate Ellington this person, is also wrong,
ta
fa
should use who, and should be in front of the comma, so D pair.
7. A
Word meaning analysis. The last sentence of the last paragraph said that
Ellington praised (complimented) Plank, so this should be a positive
us
response. So choose A. Optimistic is optimistic, assertive is positive,
progressive is advanced, with response can not echo the above concept
The positive response should be apositive
one.
rM
of "praise."
8. B
Here is Kraftwerk, the Eurythmics and Devo all side by side, following the
9.D
A

formulas A, B, and C, so choose B.
The who-guided clauses list, discovered, and released side by side,
sharing the previous wass, equivalent to which was lost,
released.
r.
discovered, and was
was
M
10. C
The main meaning is the same. There is a longer insert in the middle of
this sentence, between the two dashes. The dash is preceded by the main
language, the core noun is material, so the predicate verb in singum form,
choose C.
11.A
The point of the paragraph is The material from Plank's recording session
with Ellington was lost and discovered by his son so select A best reflects
this point.
Passage 2
12. C
Tense. What I'm trying to say here is that the coaching has been
completed, so when it's done now.
ta
fa
13. C
The singeration of nouns and all the grids. Here individual noun use, there
is no an before, so certainly take the plulus, so exclude AB, and
individuals after the need to add all the grid, because the sentence wants
us
to represent "personal career", so exclude D, choose C.
14.A
a customer.
rM
The main argument in this article is that coaching must be qualified to be
Option B is wrong in a
variety of of of, coaches need to
have good experience, but the article does not say that coachs have
"various" experience.
Coaches as long as they have the experience or
15. D
A
m
qualifications to do coaching.
Merge sentence questions. Option D uses a fixed clause to merge the
r.
second sentence into the first sentence, and correctly expresses the
logical relationship (cause and effect) of the two sentences, and is
M
concise, so it is the best choice. Option A uses multiple and connected
side-by-side sentences, which are very unsophoneable. The BC option
uses a half sign and a colon, respectively, so that the entire sentence is
also very un concise, and in the case of a clause, there is no need to use
side-by-side sentences.
16. D
Chart questions. According to the chart information, 67% work
corresponds to work-life life balance, so A is wrong, 7 1% corresponds to
interpersonal skills so B is wrong, 72% corresponds to common skills,
so C is wrong. 80% corresponds exactly to self-confidence,-so D pair.
17. A
Chart questions. As shown in the chart, the personal organization
corresponds to 61%.
ta
fa
18. B
Logical words. Both the front and back are talking about the benefits of
working with certified coaches, the previous one says improvements in
many ways, and the same report shows that companies can save money
us
more than just recouping their investments. So the front and back
19. C
rM
sentences should be connected with moreover.
Word meaning analysis. The sentence wants to express "because" and
20. D
A
m
should use "due to".
The principle of simplicity. Peril and danger are a meaning that need not
be repeated.
r.
21. C
M
The pronoun here should refer to coaches, so use plurgy their.
22. A
Coherently expressed interiors cannot be arbitrarily punctued.
Passage 3
23. B
The next sentence says this place has less water, low temperature, no
nutrition, corresponding to the B option of this question, cold desert
ecosystem.
24. B
The principle of simplicity. It's been said before, there's no need to write
per year, or each year, or yarly.
25. B
Parallel structures should be symmetrical. Here is the a mean content and
ta
fa
low nutrient availability and dash section side by side parallel, so the
dash section to be consistent with the previous, both take noun form.
26. A
us
Tense. According to the sentence, the action is an action that has already
occurred, in line with the tense of the discovery.
rM
27. A
he was not really talking about iron that has been dissolved. he was
talking about bacteria - microbes which were described of being iron
metabolizing and anaerobic. and when it comes to bacteria and microbes,
A
m
I think we choose A because he was talking about the reason of the red
color of the blood falls which is attributed to algae (bacteria - microbes)
28. C
r.
An examination of pronouns. The pronoun here refers to Blood
M
Falls,which is the name of a place, so use its.
29. D
Word meaning analysis. The words in the ABC options are derogatory and
do not correspond to the objective position of the following scientific text.
Scientists "use" salt water to conduct more electricity than fresh water,
and this "use" is not derogatory.
30.B
Here should be a structure that is now parted as an accompanying adverb,
so choose B.
31. B
The sentence waiting to be sorted is a matter of conductivity, which
sentence 3 begins
to mention, and sentence 4 begins to say that it is
ready to measure the conductivity problem. So it's best placed between 3
ta
fa
and 4.
32. C
It must be noted that there is salt water on Mars to take on this segment
of the context, in order to infer that life can completely survive in the
us
extreme environment on Earth (salt water), then it is also possible to
survive on Mars (salt water) environment.
rM
33. C
The brines here don't need to add all the grids, because this brines is the
master in the adverb of the tha boot, the main character of the provide,

r.
Labor rights
comma, labor
rights
leader Cesar
Chavez is the main phrase, moved
M
is a predicate, the main meaning in the middle can not add a comma. So
choose D.
35. C
Add or subtract sentences. The context is about Cesar Chavez moving
the sports center to la Paz, with Chavez's move at its core, and the
sentences waiting to be added have nothing to do with Chavez's
movement,
just a brief introduction to Tehachapis' location information.
36. A
Word meaning analysis. Resident is "resident" and 所 residence is
"residence", which is a ”small location, so use at not in.
37. D
There's already while in front, and there's no need to add logical words
ta
fa
later.
38. B
From the beginning of the which to the patients is an unqualified adjective
to do the insertion, inserted in the preceding adverb and the back of the
us
main sentence, so before and after the comma separated.
39.D
rM
Tense. Depending on the tense of the context and the meaning of the
sentence here,the need action occurs in the past, so it should be used in
40. A
A
m
the general past.
Merge sentence questions. A is the most concise and semantic. The
although logic of option B is wrong, the CD is too long.
r.
41. D
The brought back in this sentence is a phrase that belongs to a coherent
M
expression and cannot be interrupted by symbols at will.
42.B
The last sentence says to find a place to pull back from the daily struggles,
the next sentence introduces la Paz's beautiful scenery, B option La Paz's
idyllic setting(idyllicscenery) enhanced its function as a retreat(resort,
quiet country residence) just good to play a transitional role.
43.B
Word meaning analysis. The original idea was that La Paz would allow
workers to relax from time to time in a tense union movement, so it's best
to use the word "alternating".
44. B
The to reach farmworkers in other parts of option B echo the expand

South will be in a position to move forward, the North will never find peace, and finally urge
the abolitionists in the North to ignore the demands and rebukes of the South and continue

B The selection is correct, and the evidence is in lines 69 to 73, when the bird eats much more
dark tweezers than the light-colored tweezers that are eaten by the bird. This is because the
pollution in this area is slowly reducing, the color of the tree is getting lighter and lighter, for

What's the problem?
One of the problems with Kettlewell's The experimental method has a problem in the first
place experimental method mentioned in the first article is that lines 21 through 27 say that
Kettlewell's density of tweezers is too dense. The habits of nature's mules are not stacked, but
scattered, but Kettlewell places four tweezers in a tree and changes the whole tweezers as

colors is eaten (this results in another object, with an overshoot).

reducethe density of the delivery, and the total number of two tweezers is close to that

Passage 1
1.A
ta
fa
The subject of the rhetorical purpose. Ask the rhetorical function of the
first natural segment pair.
Option A "establishes a broad framework for compason".
First of all, we need to find out what extended in option A means is
us
spansive, and what comparison means here is not the commonly used
"comparison, comparison" but "analogy". Looking at lines 2 through 3
of the first natural paragraph, the phrase "present me," "past me," and
rM
"future me" is like echoing each other in the same space. is to liken the
three "I" analogies to the relationship between sound and echoes. In
addition, lines 22 through 23, the same as the scheme, correspond to
the frame work in the correct option A.
A
m
Option B is a interference item, which is wrong because there are no
competing "views or perspectives" on the same thing in the article.
2.B
r.
Details. Who does "we" mean in the first sentence?
The evidence is in the second sentence of the article (lines 1 to 2). The
M
word "we" in the first sentence refers to the present we and who we had
been and who we will be three people.
3. D

sleeves, according to the article, how will he cope with the frustrating
situation?
The evidence is in line 21, give it a good try corresponds to the correct

hard, even though he's sure he won't win the race.
4.B

The subject of the rhetorical purpose. Ask the function of the 3rd natural
paragraph is...?
In this paragraph, the author talks about several possibilities for what
rM
kind of person it will be in the future. Because it is impossible to choose
who will be in the future, the varieties of option B are wrong. Option A
means "frustrated by the predictability of his older person", and
predictable in this option means "unsurprisingly, conceivable;
6.C
A
m
mediocre; unimaginative".
Vocabulary questions. Line here means a series of related things, and
r.
the kind in the option means close.
M
7.D

According to lines 78 to 82 of the article, people may not know why they
met when they met, it may be many years, suddenly understand. The
draw you together on line 78 corresponds to the are connected to each

rM
B) Intuitive insight and proactive awareness.
C) Personal discovery and public information.
D) Over-used ideas and original ideas.
According to lines 77 through 83 and 83 to 86, it is often only after years
A
m
of understanding that it turns out that "we have more in common with
each other than I thought we would". But it can't be said that people are
completely unaware when they know each other, people get to know
through an intuition that "the other person is similar to themselves"
r.
(corresponding to line 85 of the of course you did know) to become
friends, but "the other person is similar to their own" intuitive insight
M
may take a few years to become active awareness.
Passage 2
11.D
The subject of the rhetorical purpose. Ask the rhetorical function of the
full text. The full text directly puts forward some requirements for the
U.S. foreign policy after Washington leaves office, which is a set of
principles of foreign policy in detail. He is advising and encouraging
citizens to become more knowledgeable about international relation. he
does not make a clarification but he is triggering them for knowledge .
he has been using the imperative sentence form the whole passage to
encourage the people for gaining knowledge about international
relations. plus, lines 50-52 show the same scenario
12.A
ta
fa
Vocabulary questions. Enjoin means "requires (some kind of action,
attitude)"
prescribe (an action or attitude) to be performed or adopted
The prescribe in the option means "predate; specify that some action
us
should be taken"
state authoritatively or as a rule that (an action or procedure) should be
The two mean close.

Details. Ask the author what kind of relationship it implies with other
A
m
countries is in the best interest of the United States?
Evidence in lines 18 to 23, against... Passionate... Amicable feelings

A
m
parentheses in line 52, what rhetorical features does fellow-citizens
First, we need to know what conjure means "implore, pray" (implore
someone to do something)
qualify here means making a statement by adding restrictions or
r.
limitations or observations. A is a correct choice. he did not plan to
engage the audience
M
19.B
Details. What does it mean to ask the last sentence?
The last sentence is short. Here let us stop is followed by the last two
sentences (lines 60 to 64), which are linked to the meaning of "previous
agreements with other countries, for those already signed, to be
faithfully executed, but to grasp a degree beyond the terms of the
agreement (involving political relations), you must stop."
Option A is wrong in Washington by saying that there should be only
business relationships and no political alliances, while Option A seems
to be saying that as long as the United States is damaged, it can't do it.
According to Washington, it's also icing on the line if it's just to help
other countries lose money on business, and the key is not to have
political alliances.
20.C
Details. Q. According to the article, the best economic policy in the
ta
fa
United States is...?
According to lines 60 to 63, as little political connections as possible

sea otters, the author adopts... Provide a good reason?
r.
if you read lines from 50 to 50. you can tell that he attributes his case to
the decline of other sea species which have been studied earlier by his
M
colleagues. he meant of the prior studies on those species showed that
their decline was caused he killer whales then the case of sea otter is
the same. i would go with choice B. i cannot find a support for unlikely
conditions in choice C
23.B
The subject of the rhetorical purpose. Ask about the rhetorical function
of the second natural paragraph.
The focus of the second natural paragraph is not on "calculation
results" (option A), nor on "methods of observing and collecting data"
(option C), nor is it about challenging a conclusion (option D). The
second natural paragraph states that there is a significant reduction in
the number of sea otters, one is the rapid increase in the number of orca
whales and the other is that the killer whales have changed their
behavior patterns. The first possibility is very small, so focus on the
second possibility. This is an introduction to the reasoning and thinking
24.D
ta
fa
process behind the study, so choose B.
The subject of the rhetorical purpose. Ask about the rhetorical function
of the third natural paragraph.
us
The third natural paragraph is to say that there are three species of orca
whales, the most likely to lead to a rapid decline of sea otters is one of
them called transient, specifically because of the change in the basic
rM
food ingredients of transient (lines 31 to 36). At the same time, it was
recorded that between the 1970s and the 1980s, the number of pinniped,
the main food of the orca whales, had declined significantly (suggesting
that they might have been eaten up quickly during this period), and then,
A
m
immediately after the 1980s, the number of sea otters began to decline
rapidly. This may be because sea otters have replaced pinniped and
become the main food for orca whales. This natural paragraph is an
overview of the reasoning process behind the theoretical hypothesis put
r.
forward by the author, so choose D.
M
25.B
Details. Ask the author and his team what questions the study directly
answers?
The article did not mention the "if the mammals have eaten up, transient
orca whales will not eat fish anymore" this question, so A wrong.
According to lines 25 to 26, what in offshore oceanic waters' orcas eat is
not the article's concern, so C is wrong. How the recipe for resident orca
whales changes is not something the article cares about, so D is wrong.
According to lines 42 to 46 of the article, the author explains that
because pinnipeds are no longer enough to eat, they change recipes.
Line 44 of the spanded their diets corresponds to the a shift in the diet
in the correct option B. So pick B.
26.C
The question of seeking proof. Ask the evidence of the answer to the
ta
fa
last question, see the analysis of the last question.
27.A
Vocabulary questions. Association means the act of associating, while
associate means to come or be together as partners, friends, or
us
companions (and ... Social interaction, mutual company)
The intertaction meaning in the option is close.
rM
28.D
Separate proof-seeking questions. The researchers put forward a
theoretical hypothesis as to why the number of sea lions has declined.
Which of the following sentences supports this theoretical hypothesis?
A
m
Line 61 to line 64 says that analysis of population (refers to the number
of orca whales and sea lions) and energy (refers to the amount of heat
required by orca whales and the amount of heat that sea lions can
provide as food) has shown that a relatively small change in the
r.
behavior patterns of orca whales can lead to a decrease in sea lions.
M
29.A
Vocabulary questions. Figure means "play a role, sing the main
character" (play a large role in a situation or event)
Example.：He figured largely in opposition to the Bill.
He was a leading figure in the opposition to the bill.
Option A means close.
30.C
Chart questions. Because the problem is the greatest decline, the
location represented by the line with the highest and lowest difference
between the highest and lowest points in Figure 1 is named Kalkaska
Island.
31.A
Chart questions. Because, according to Figure 2, great whales stopped
sharply in the 1960s and 1970s, it was just as soon as the sharp decline
ta
fa
in harbor seals began, suggesting that the killer whales had almost
eaten up in the 1960s and 1970s and started eating the harbor seals
again. So option A is correct.
Figure 2 does not show whether the number of killer whales has
us
decreased, so B is wrong.
Figure 2 shows that great whales did not recover after 1970, so C error.
Figure 2 shows that in 1960, great whales accounted for about 75% of
rM
the food of orca whales. By 1966 only, the proportion was close to 100%,
so D was wrong to say that "before 1970, the great whales did not
32.D
A
m
account for a large part of the food of the orca whale".
A comprehensive analysis of the picture. Q According to the article and
Figure 2, is the following statement correct?
r.
Lines 37 - 49 are giving a support to choice D.
M
Passage 4
33.C
The subject of the rhetorical purpose. Ask the author what rhetorical
features are there in using "restrictive silo" and "walled garden" on lines
33 to 34 to describe certain social platforms?
Focusing on the words "restrictive" and "walled," these social platforms
allow people to socialize in a restricted, walled environment, and then
look for answers on lines 33 and 34 before and after this sentence.
These social platforms designed... Do not allow outward links (lines 26
through 28), corresponding to the correct option C in the limiting user
interactions. In contrast, "diversity that the world wide web hardly
envisioned"(lines 37 to 38), the world wide web is not restrictive, not
walled. In addition, from the full text, the author is also critical of these
social platforms. So pick C.
34.B
features are there to quote Bell in line 4?
ta
fa
The subject of the rhetorical purpose. Ask the author what rhetorical
The first thing to find Bell's sentence means that "the ecological
environment of our press has changed the most in the last five hundred
us
years". This is clearly an unprecedented change in the press in recent
years.
rM

r.
dominant forces corresponding to the question ... To the demands
M
corresponds to the modeify contents in the correct option C.
37.C
The question of seeking proof. Ask the evidence of the answer to the
last question, see the analysis of the last question.
38.B
Details. The author suggests that "news written in the public interest" in
lines 55 to 56 is increasingly being replaced by what kind of news?
Evidence On lines 54 to 58, many news organizations move away from
"news written in the public interest" and instead write "news that chases
web views and clicks (like junk food)."
39.D
Details. Ask the author to criticize the credibility of online news, and the
author anticipates what views might be expressed against the author's
criticism.
ta
fa
The evidence is in lines 68 to 70, and former journalists have made
mistakes, written false news, sometimes carelessly, sometimes
deliberately. Line 68's harvey got things wrong corresponds to line 70's
us
by intent corresponds to the correct option in D purposely.
40.C
The question of seeking proof. Ask the evidence of the answer to the
rM
last question, see the analysis of the last question.
41.D
Chart questions. Ask the respondents below a few statements about the
A
m
respondents' views on news sources, which one is best supported by
Figure 1?
A) News in paper newspapers is more accurate and reliable than
websites other than social media. According to Figure 1, the first bar in
r.
the second set of bars is lower than the first bar in the third set, so A is
wrong.
M
B) Websites other than social media analyze and comment on news
better than television. According to Figure 1, the third bar in the third set
of bars is lower than the third bar in the first set, so B is wrong.
C) Paper newspapers are better at bringing new news than social media
platforms. According to Figure 1, the second bar in the second set is
lower than the second bar in the fourth set, so C is wrong.
D) News on sites other than social media is more accurate and reliable
than social media platforms. The first bar in the third set of bars is
higher than the first column in the fourth set, so D is correct.
42.B
A comprehensive analysis of the picture. What information does Figure
2 actually show that contradicts the content of lines 54 through 75 of the
article?
i would not go with A as a challenge with the passage because the
passage did not make a specificity of France and Italy. Choice B is
ta
fa
correct.
Passage 5
43.B
us
Vocabulary questions. Resolve means "solve a problem, dispute, argue,
etc." (settle or find a solution to a problem, dispute, or contentious
matter)
rM
The meaning of the settle in the option is close.
44.A
Details. Ask Estrada's view in Passage 1 that if Saturn's rings had been
A
m
built earlier, what would have happened to Saturn's rings?
In lines 15 to 18, Estrada argues that there is a sharp contrast between
the composition of the inner edge of Saturn's rings that are now
observed, and that if Saturn's rings are really old, there should be no
r.
sharp contrast on this composition. Sharp contrast is reversed and
M
corresponds to the unform in its makeup in the correct option A.
45.D
The question of seeking proof. Ask the evidence of the answer to the
last question, see the analysis of the last question.
46.D
The subject of the rhetorical purpose. Ask Passage 2 what rhetorical
features did the last natural paragraph mention of dinosaurs?
The last natural segment is that the results suggest that Saturn's rings
were formed during the Cretaceous period on Earth, the age of
dinosaurs on Earth. Because generally speaking, the reader about when
the dinosaurs were animals, probably have an impression, a little
familiar, so the mention of dinosaurs is to show that the formation of
Saturn's rings is not in a particularly early period, but in the Cretaceous
period, relatively not so far away. So choose D.
ta
fa
47.C
Details. Ask the authors of Passage 2 what they think is the part of
Saturn's orbital change?
Evidence in lines 59 to 62, the tides... enlarge ... orbits so fast
us
corresponds to the international in the dry and the tidal activity in the
correct option C.
rM
48.B
Vocabulary questions. encounter means "encountering difficulties or
disadvantages, encountering; facing" (unexpectedly experience or be
faced with something difficult or hostile)
49.A
A
m
Face in the option means close.
Two relationship questions. The first article is an overview of two
r.
diametrically opposed views (one that Saturn's rings were formed early,
the other that Saturn's rings were formed late) and their respective
M
evidence, and the second presents only one view and its evidence. So A
is right.
Both articles talk about hypothesis and evidence, the second article
focuses not on methods, so B error, the second article research is not
based on the theoretical model of the first article, so C error. The first
article describes more than just one hypothesis, but multiple
hypothesis; So D error.
50.B
Details. Ask what kind of evidence is mentioned in both articles?
Evidence is in lines 47 to 48 of Pasage 1 and Passage 2 from lines 66 to
67.
51.D
Two comprehensive analysis questions. Ask Esposito in Passage 1 what
is most likely to be the most likely response to Passage 2's assertions
ta
fa
about Saturn's rings in lines 89 to 93?
Lines 89 through 93 say that Saturn's rings were still relatively young
(100 million years ago), and according to lines 19 to 28, this is partly a
question of Esposito's claim that it was "generated 100 million years
us
ago." If Saturn's rings had been built 100 million years ago, it would
have been possible that only a satellite or an all-ice object had hit Saturn
and been crushed. But the problem is that in the last few billion years,
rM
no cerbo has orbited Saturn or the solar system, and it is impossible to
be crushed and supplied to Saturn Rings as a raw material for debris.
The iccy body on line 24 is torn apart, corresponding to the debris in the
52.C
A
m
correct option D.
The question of seeking proof. Ask the evidence of the answer to the

C. The article doesn't talk about other ways of libraries can attract more
patrons, other ways, so there is no way to say so there's no way to say
that makerspaces are one of many ways not D.
The main part of the
article is also not to say that library's current facilities and services are
r.
not related, need to be adjusted (adapt) in order to remain relevant, so do
not choose B.
This question chooses A, the last sentence of the article
M
also said makerspaces offer new way for libraries to enrich their
communities. . So the whole text is mainly about making patrons a better
service for the library.
5. D
Excluding AC (A's material repeats, C's also doesn't need it), B's to do is
not structured correctly, and here should be a noun or adjective to modify
machines, so you can only choose D.
That is, materials for X, Y, and Z.
Where X is arts, Y is crafts, Z is building and repairing machines.
6. D
Transition sentence. The last sentence says That FabLab provides
Jacobs with tools such as vinyl cutter and laser engraver (i.e. and so on
resources), and the next sentence says that FabLab also provides
workshops and events, so the best transition sentence is "otherthan that",
ta
fa
which is option D.
7. A
Transition sentence. This sentence is followed by the content and
configuration of makerspaces that can be tailored to the user's needs, so
us
you need to match option A and say, "Because these places (i.e.
makerspaces) are versatile." BCD has nothing to do with context, neither
mentioned below.

The context doesn't say what's wrong with the library, so there's no
problem with remedy, revise, and correct.

Tense. Here according to the context (provided) and sentence meaning
M

10. D
Sentence connection. Here a total of two sentences, there are already
words because, there is no need for so, there is no need for a period.
Although therefore is an adverb, does not cause too many interconneth
problems, but there is a because, the meaning of this layer is not needed.
So, between the previous because clause and the main sentence after it,
just use a comma.
11. B
Pronouns. Here you need to refer to the creators, so use the plulus theem.

All three go side by side, following the formulas of A, B, and C.

start down. Here's how Andrews got his degree, worked for a while in insurance
companies and banks, then at the Department of Agriculture, and says she likes
different theories to new issues, suggesting that actuarials are committed to
"finding practical solutions to real-world problems." That's what attracted
r.
Andrews into the field.
4. B
M
Logical hosts are consistent. The whole sentence is accompanied by doing stints
at an insurance company (which has been done in an insurance company for some
time), so only one can do the main phrase.
5. A
start down. The next paragraph says that Andrews' team helped develop a public
health information system that helps USDA conduct predictive analytics in many
ways, so the chalenge that team A faces is "detecting how USDA uses predictive
analytics" to help USDA better use predictive analytics.
6. D
The main meaning is the same. Compile and organize are the predicates in the sat
clause, while theth refers to the previous system, sings, so-called verbs to add s.
7. A
Express style. Of the four options, only monitor is the most standardized
ta
fa
expression of "supervision", while the others are spoken expressions.
8. D
Combining sentence questions, ABC is not concise.
us
9. A
The title asks for an example to support Andrews' contribution to her field , which
rM
is the predictive analysis of actuarials , so only A meets this requirement , and
when it comes to training actuarials in the application of predictive analysis , that
is her contribution to the field . None of the other options mention the contribution
10. A
A
m
of predictive analytics.
Tense. What the original text is trying to say is that I don't know if predictive line
analysis will become more common among actuarials. So use the general future.
11. D
r.
The full text of the main thrust. The full text says what Andrews has contributed
M
to predictive analytics as an actuary, so Andrews' presence increases the
likelihood that predictive analytics will be rolled out in actuarial science.
12. B
Request to undertake subsequent references. The follow-up quote says, "Isn't
there anything sacrosanct?" "Obviously criticizing Pride and Prejudice and
Zombies ruined the previous Pride and Prejudice classic. So pick B.
13. B
The principle of simplicity. The other options have a degree of repetition.
14. C
The original text wants to express "her family's expectations", so there needs to
be all the grids behind the family, and the expectations are not needed later.
15. B
All events in the book or story are tackled correctly using the present tense. but
ta
fa
when he needed to talk about a book or a story as a whole which has been made
long time ago, he had to use the past tense. choice B is correct
16. B
us
This here refers to Elizabeth. The original sentence means to present her
intellectual strength and rebellious spirit (i.e., refusal to obey social customs) by
rM
portraying the hero Elizabeth as a fearless zomie hunter.
17. D
All that is said below is the meaning of mash-ups in teaching.
18. C
A
m
Word meaning analysis. The argue here means .：If you argue that something is
true, you state it and give the reasons why you think it is true.
19. A
r.
Two nouns are side by side, with no commas in the middle.
20. B
M
The main meaning is the same. The main language of this sentence is popularity,
and countless nouns are handled like three singles.
21. D
Add or subtract sentences. No, because the context of the original text is a genre
of comprehensive commentary mash-up, there is no need to include a specific
message about Sense's book in the middle, which is an inexplicable message.
22. A
all writers should consider penning a mash-up. this restates the whole argument
in the passage and matches the preceding sentences
23. C
Starting from the dashed part of the question, is the scholars and professionals of
the same language, so can only be people to do the lifesionals of the same
ta
fa
language, and, the back of the side-by-side components are also people, so 23
questions should choose ecologists, and need to follow the formula of three and
above side by side.
us
24. A
One obvious signal word in the sentence waiting to be sorted is the think
definition, indicating that a definition appears earlier, so sentence 1 is just about
rM
the definition of geography. So put it after the first sentence.
25. C
The following is a variety of interdisciplinary collaborations between the winners
endeavors.
26. D

m
of these geography awards, so it should reflect the geographers' wide-ranging
Two examples that already exist are the interdisciplinary collaboration of
r.

27. B
M
Now parting words as accompanying adverbs, preceded by commas.
28. C
there is a point of contrast when you transition from a positive claim to a negative
claim for this reason, we use choice c.
29. A
There should be a limited sentence here, there are many institutions, and the
researcher identify comes out of 89 institutions that have been reamed for a
certain period of time.
30. C
Express style. decommission is to officially stop using weapons, a nuclear power
station, etc. That is, decommission is generally used to stop the use of weapons,
choose C.
31. D
The principle of simplicity. ABC is relatively long.
us
32. B
ta
fa
nuclear power plants, etc., while BD is an irregular and irregular expression, so
The word fortunately at the beginning of the paragraph tells us that the whole
rM
paragraph below is about the lucky side of geography, and the following two
sentences do say the lucky side of geography, so the logic of "and" should be in
the middle of the two sentences.
33. C
A
m
Word meaning analysis. Behind the dash section is the human language (that is,
those refers to people), so you should use assure instead of ensure or secure
(these two need to be picked up later to do the guest language), and insure is on
insurance, that's not right.
r.
34. B
M
ACDs are run-on errors.
35. B
Transition sentence. The last paragraph is the question, the next paragraph is the
answer.
36. D
There is no obvious logical relationship between the front and back sentences. In
the previous sentence, the researchers assessed the role of acupuncture in
patients
with
chronic
pain,
and
the
following
describes
some
of
the
characteristics of chronic pain. The two sentences are neither causal nor
examples, nor side by side.
37. C
This sentence in the either or is a fixed match, in which certainly can not appear
colon, so exclude BD, and AC's with front has a comma, so this need not be
considered, the problem is or before the comma, if not, will make people think that
ta
fa
the content behind or is followed by the with inside, but in fact or is followed by
the wire in front of the other, so or must have a comma before the with part of the
insertion, so can be deleted, This allows or to follow the front either.
us
38. A
There is no way to turn out a """ word after the translation, so you can't add all

Merge sentences. ABC is not concise.
Comparing the chart, it can be known that the hollow dots corresponding to the

41. D
M
The chart's springal cortex, cingulate cortex, and caudate correspond to solid

The principle of simplicity. Produce and yield repeat, say once, another, second,

The subject of the rhetorical purpose. Ask what the rhetorical function of the last natural
ta
fa
segment is?
The last natural paragraph (lines 65 to 70) states that "in statewide voting, the change in the
number of 10,000 votes (caused by different polling places) does not seem to be significant."
us
("The change in the number of 10,000 votes caused by different polling places" here refers to
the experimental results mentioned in lines 49 to 52 of the article.) But 10,000 votes would be
rM
enough to influence the outcome if there was a very small gap between the two sides. In the
2000 presidential election, for example, Bush and Gore had a 1,000-vote gap (not just
statewide, but nationally).
Thus, in some cases,1000 votes is enough to influence the
A
m
outcome of the election, not to mention 10,000 votes. . .
Lines 65 through 66 "In statewide voting, the change in the number of 10,000 votes (caused
by different polling places) does not seem to be significant". This sentence is exactly one
objection (criticism of the author's argument) that may be raised by those who oppose the
author's argument. The author comes out on his own initiative and then deals with this
r.
criticism in a larger context (in most cases, 10,000 votes does not matter in large elections,
M
but 10,000 is important when some candidates are close to each other). This has also
happened, as in the 2000 Bush and Gore campaigns. So choose A.
39.D
Infer the question. What are the weaknesses of the author's assertion in the last sentence of
the full text? This question is relatively novel, the need for candidates to master what kind of
general reasoning is a strong reasoning.
The authorconcludes by saying "Triggers matter",which means that "some of the factors that
trigger the voter reactionat the polling place are not ineffective." "The last natural paragraph
of the article is to say, "Even if the gap of 10,000 votes sounds so small, it is important in some
large elections in which the total number of votes won by candidates is very small". But there's
a problem with reasoning here. The change of 10,000 votes may，It may not be the polling
place. not be due to the change of 10,000 votes caused by the triggers of the polling place,
ta
fa
or it may be caused by other factors. So you can't derive triggers from a changeof 10,000
matters votes. Triggers have an impact on human behavior and need to be introduced with
general reasoning. The article in the line gives a detailed example. a detailed example of how
triggers Examples that affect people's behavior are derived. affect human behavior on lines

reasoning is from "special specific" to "general" reasoning, in the process of general reasoning,

we should try to find more specific examples to reach a general conclusion. The author gives
Chart questions. First, find the two data columns B corresponding The two data of the
column, that is. to the object described in the question, namely 0.583(Initial results)）. and
0.560(Results after controlling for the demographics).（ Then pass on the options one by

one.
M
Because the entire table ABC three columns are written in increased percentage
likelihood,and the values in the table are positive, indicating that the ratio of people voting in
favor has increased, option A is correct.
Because 0.583 is obviously not equal to 0.560,option B is incorrect.
Because there is no information about other initiatives in the table, option C is wrong.
Option D is incorrect because there is no information in the table about the proportion of a

In this paper, other factors that may affect the outcome of the vote, such as differences in

Ask which of the following is true, and you can best support the explanation given in lines 64
through 67.
Line 64 to line 67 says that with lizards, the number of spider species is small, partly because
lizards eat spiders, and for one reason, some spiders eat, lizards eat. Lizards rob spiders of
food. Originally because the lizard size is Spider size is small, everyone's. large, spider size is
small, everyone's expectation is that the spider eats something different from what the lizard
eats, the spider should eat some smaller animals, the lizard should eat some bigger animals.
But in fact, their recipes overlap, and there are quite a number of animals that spiders eat and
lizards eat.
A) The total biomass (total weight) of food eaten by spiders on closed and unsealed islands
with lizards is less than the total biomass (total weight) of food eaten by spiders on closed
ta
fa
islandswithout lizards. This shows that as long as there are lizards, the total weight of food
that spiders eat in their stomachs is lower, indicating that some things are snatched and eaten
by lizards. You can also support the contents of lines 64 through 67.

B) Spiders on closed islands without lizards have a much higher survival rate than spiders on
closed andunseeded islands with lizards. In addition to this condition, it may be because
rM
lizards rob spiders of food to eat, but it may also be caused by lizards eating spiders (line 63,，
the obvious one is predation). That Line to line, but cannot rule out the lizard will eat spiders

lizard's can to eat spiders can be rule out, so it is not best option to support lines 64 to 67.
A
m
C) On unseeded islands and closed islands with lizards, there are fewer cobwebs near the
ground (which lizards can easily reach) than on closed islandswithout lizards. This option only
describes the lizard's predation of spiders. So wrong.
D) On unsealed islands, the average size of insects eaten by spiders is much larger than that
r.
of insects eaten on closed islands with lizards and closedislands without lizards. Because the
M
situation referred to by D does not show a difference in the average size of the insects eaten

there are lizards or no lizards), the situation described by D said this situation, also can not

Since We have no way of knowing which type of body size information. there is no information

Because there are as many as nine predatory. preys for Anolis lizards in Figure 2, 9 it is clear
that it is not dependent on one food. So the C option is correct.
Option D is incorrect because there is no sample size for food for spiders and lizards,

soldiers, all out of a life, so that the poor and the rich pay equal, which is
unreasonable. If it is a permanent army, that is, usually pay taxes to
support the army, when paying taxes can be stipulated that the rich pay
more, the poor pay less. It makes sense for the rich to be more and the
poor to be less. Therefore, the establishment of a permanent force is more
equitable than the establishment of a militia in terms of the cost-sharing

The punctuation at the end of the sentence is determined by the main
sentence, where the main sentence (leaders must evaluate) is the
statement sentence so that the end of the sentence can not use a question

order, can not use the question language sequence, so choose C does
not choose B.

inflated, or overstated
rM
The meaning of the over in the alternative is close.
4.A
Details. Ask according to the article, in the author's eyes, the
A
m
father is basically what kind of image?
According to lines 9 through 10, it can be seen that the father
is the rule-setr at home, and according to line 29 to 34, the
r.
father only said "my son and I are going to talk tonight", which
M
is equivalent to giving the rest of the family a wake-up call,
waiting near the reception room not to make a 1 sound, not to
affect our conversation. It can be seen that he is a different
person at home.
The presence in the correct option A does not mean "existence",
but
"meter,

It
doesn't
mean
"existence",
but
"instrument,

(the
impressive

According to the article, the author's father and the author of
childhood talk about this matter, the author does have a strong
emotional impact, what kind of emotional impact, is to make
him very afraid. Lines 35 through 46 say the details of the
conversation, BUT OVERWHELEMED IS TOO MUCH ,

The drama in option D means "a series of exciting,

The question actually examines the details about the purpose
of the experiment and the results of the experiment. According
to lines 33 to 37,the purpose of the experiment is to know: What
is people's attitude towards donating money? Is "although the
project will generate administrative costs, but as long as their

own donated money is not spent on administrative costs, is
willing to donate"? Or "as long as there are administrative costs

charity, not administrative costs, administrative costs have

effective in solving this problem in non-laboratory experiments

(i.e. experiments in real society). Which of the following
sentences supports the above conclusions?

The subject of the rhetorical purpose. Ask the author what

rhetorical function is it toquote the word"fall"in line 8?
M
One of the uses of double quotes is that words that represent
quotation marks have a special meaning. In this article, the
representing fall is different from what we usually see. A normal
fall certainly has no control over your body or direction.

strange, so the use of curiously),）and fortunately the other
animals are leaning down (leaning down is more normal, which
gives the researchers some peace of mind, so use reassuringly).
The way ants fall is different from the way people expect them

Chart questions. Q. Is it right or wrong to say that a student

Because there is no information about cats in the picture, the
student's assertion must be wrong.

A comprehensive analysis of the picture. Which of the following
is supported by the data in the figure for the relationship
us
between the weight of the various ants and the level of gliding
efficiency?
rM
A)Several ants with lower average weight have higher gliding
efficiency levels than several ants with higher average weight.
This sentence is not absolutely said, but that there is such a
A
m
tendency. From the picture, this is true, except that T is the
exception, the other point is roughly in line with A's statement.
So A is correct.
r.
B)Several ants with higher average weight had higher gliding
M
efficiency levels than several ants with lower average weight.
This is the opposite of the picture, so B is wrong.
C) In all cases, several ants with lower average weight had
highergliding efficiency levels than several ants with a higher
average weight. This sentence is dead, and we can find a
counter-example in the figure, that is, T is This kind of ant, the
weight is lower an ant that weighs less than S,but T's gliding
efficiency level is not higher than S,but lower than S. So the in
all cases of option C
is wrong.
D)Individuals who weigh the same weight have the same level
of gliding efficiency. There is no information in the icon that

fa
reflects the individual ant, and both the horizontal and vertical
axes indicate information that is average, so we don't know the

Passage 1
1. A.
Details. Q What did the community neighbors' reaction to Felix's
impending marriage, according to the author's description, indicate?
According to lines 7 through 11, neighbors heard that Felix's day of being
single was finally settled, and set aside their animosity, but were united
in their enthusiasm to help with his marriage. That is, priority is given to
Felix's marriage.

Details.
The portrayation of Mrs Dickson's character in the question suggests that
the author thinks she...?
According to lines 16 to 20 of the article, Mrs.Dickson made a long
statement that she could not be separated from her only child, and Felix
was forced to assure her that she would be married with multiple sons
rather than fewer daughters (i.e. that the man would move to the woman's
house). Because Felix was done by compelling, she was a bit of a perse.

3. A.
The main topic. Ask which of the following options is a general
description of what happened in the article.
The article is about Felix to get married, before marriage was forced to
promise to live in the woman's house,Felix's mother comforted herself,
said that her son moved not far away, he also has a daughter melissy, and
then every day at home hairline, the surface looks very calm, in fact, still
want son. Just after her son's honeymoon, she went to the woman's
house to see her son, and then helped with some work. The fact that her
son got married and went to the woman's house was a very important
change for Mother Danbury, who made some adjustments. So choose A
(notethat the verbs of the four options are used in general present, which
is a common usage in novel stories and news headlines, and are vivid
when replacing the general past that should have been used with general
presenttime).
4. A.
Details. Ask, depending on the context, what does the author mean
by"had their trouble for their pay" from the person visitingMother
Danbury?
According to line 32 of the article, these people are coming to condole
with Mother DanBury (right... The tone of condole with the article is
somewhat ironic, that is, these people are somewhat lucky to come to
Mother to mention this bad thing to see her sad, but Mother Danbury is
brave enough to say: "Men always want to find a wife, women do not come
to the man's home, men go to the woman's home no big deal, I'm not sad)",
so that these people in the purpose of the visit encountered difficulties
their trouble for their pay).

Danbury's friends may not know that she has several feelings mixed up"?

still wants to see her son，outwardly(her soul longed for a of this sight

A

6 .C
Details. Ask Mother Danbury to work when she comes to Mrs Dickson's
house because she wants to...?
According to line 65 to line 74 of the article, when Mother Danbury arrived
at the woman's house, Mrs. Dickson insisted on staying with her and
posing as Felix, much to Mother Danbury's disdain, and she wanted to
have a part with her son who didn't want tosit. So even though she was
r.
the best alpaca she'd ever ， worn as a guest, she got up to work
M
(regardless of the factthat she mightget dirty).
So she wants a part,that is, she wants to be the family's another member.
7.C
The subject of the rhetorical purpose. Ask the author what rhetorical
features are there in lines 72 through 73 that refer to "the prominent manmade flowers in the glass cover and the shell-made house model on the
fireplace"?
Lines 69 through 74 say that Mother Danbury doesn't want Mrs Dickson
to be with her, but wants to have a part in her son's life, and
mostimportantly, shedoesn't want to sit in the hall and look at "a
prominent model of a house made of shells in a glass hood and a
fireplace." Glass here refers to glass dome(glass cover) and places wax
flower in a glass cover. Shell House is a model house made of shells,
stone, or cork. Both were popular home furnishings from the 19th century.
The most critical part of this sentence is the use of a staring before wax
flowers, staring， which means that the artificial flowers seem to be
staring at Mother （ Danbury, which is to make Mother Danbury feel
ta
fa
uncomfortable in a strange environment that is like a prison (line 77 uses
a her prison).
The echo of the C option means "to make a recall (something, action,
event) "(of an object, movement, or event) be reminiscent of have or
shared with.

The subject of the rhetorical purpose. Ask the rhetorical function of lines
74 through 79 what kind of tone is created?
First, let's translate lines 74 through 79:：
A

rM
"When Mother Danbury put herclothes up around her waist, rolled up her
sleeves, and tried to get up and work, she was guided back itwasn'tappropriate to use the wordguidance, she was carried back to
where she was. Mrs. Dickson, while lifting her,kept affirming that she
would befrightenedby any work that would be done by theguests who
came to the house.
The scene is more dramatic, so option A is the correct option.
A)The dramatic tone of the character's character, which suggests that
Mother Danbury's view of Mrs. Dickson's treatment of her is somewhat
exaggerated.
r.
9 .B
Details. Ask the article whatresulted from Mother Danbury's visit.
Evidence on lines 87 through 89, as it seemed to her perceived，in the
M
correct option B, Felix went home,and Mother Danbury felt felix go home
as before (her broken relationship with her son continued). This is how
she felt (not necessarily true) after she went to the woman's house and
did housework with her daughter-in-law and family. A Why is option A
wrong, because if you choose A，it means that Mother Danbury is worried
about what the gossipy neighbors will think, and after a day at the
woman's house, she feels even more worried. The whole article is just the
last mention of the neighbors, so the article doesn't show that this visiting
changed Mother Danbury's concern.
Added: Line（ line 89 of gossip is a noun that means "people who love to
talk aboutother people's private lives" (a person who would like to talk
about other people's private lives).

means a judgement or decision reached by reasoning) that "the effect of
sounds that are not directly related to the food you eat has on how people
feel about the taste of food, which Spence has studied".
Note that the conclusion in the heading does not refer to the conclusion
of a study conducted by Spence, but rather to the "effectof sounds that

taste offood, whichSpence has studied" in itself.

The subject of the rhetorical purpose. Ask the author in lines 10 through
14 to give an example for what?
Lines 10 through 14 say that scientists have long known that strawberries
are sweet or light, and that the olfactory receptors in the noses of
strawberry eaters feel much about which molecule strawberries are (i.e.
taste is influenced by smell).
This is a study of the influence of taste on smell, and Spence's study of
the effects of taste on hearing is related.
13.D
The subject of the rhetorical purpose. Ask line 19 to line 20 whatworks
with"thin, homogeneous, stackable paraboloid"?
thin homogeneous, In stackable paraboloid, homogeneous paraboloid is
a relatively rare subject word, meaning "double parabola”, stackable
means "can be neatly stacked", the whole is to say that the"pringle"

the word" snackification" In order to...?
Snackification is a new term that has become more popular in recent
years, referring to a meal that does not eat three meals a day and is called
Snackification between eating less and eating more. (The explanation
found online is thatthe traditional threemeals a day is being challenged
globally as a new generation of eaters are opting for snacks rather square
meals.) It's' called snackification. . .
The word is not exactly used in English, so the author uses double quotes
when using it.

respective articles, but the two passages cite (recourse) precedents for
different purposes, so what is the difference?
We first go to the two passages to find the place where the precedent is
invoked and find the place where passage 1 invokes the precedent, right

the United States,which is to sayprecedent. This paragraph is about the
power of Indian self-government, which has never been eliminated.
Several decisions by U.S. government courts have also upon this power.
So the correct option is A. Passage 1 cites precedent as an effort touse
precedent to assert that Congress has the power to deal with relations

The subject of the rhetorical purpose. Ask the author in the first paragraph
what Ross's background as a scientist is for?
Here's a background. Doctors often kill a bacterium with an antibiotic, but
over time, the bacteria may become resistant to that antibiotic (an
evolutionary act) and become resistant, and then the antibiotic becomes
useless.
The author says Ross is a zoologist, not a physician. But the experiment
introduced in this paper is related to how to eliminate and prevent
bacteria from be resistant to antibiotics. This is the area of concern to
physicians. So Ross is doing interdisciplinary cross-border research,
and he's an outsider (but instead allows him to break through the
traditional thinking of medical professionals) and give an unsymical
perspective on how to solve the problem of bacteria's resistance to
antibiotics.

prevent bacteria from collaborating with each other. It means that there
was no such medicine before, and now some of it will be developed. It
doesn't match the meaning of the article.
C means that this paper describes a study that suggests that a new
approach may be possible to treat bacterial infections (against bacteria
that cause bacterial infections).

a bacteria.
According to lines 64 to 70 of the article, P. aeruginosa sent siderophores
out and wanted to get iron ions back through these siderophores.
Nitrate causes the siderophores sent by P. aeruginosa to bind to the ions
rather than to the iron ions, which results in P. aeruginosa not always
getting the iron ions it needs, which are useless to P. aeruginosa. Then
P. aeruginosa still want to get iron ions, but do not know is nitrate in the
troublemaker, how to do, poor it can only continue to send more
siderophores, and the production of these siderophores is the need for
nutrition and energy, the nutrition and energy that could have been used

A) Compared to the other two groups, the subjects in the contentment
group entered the second phase of the "longer than who persisted"
experiment and held on for a shorter total time, but took the same amount
of time per attempt.
The total time that the Content group adheres to is indeed the shortest,
but the time spent on each attempt needs to be divided by the bar value
of each group in Figure 2 by the bar value of Figure 1, and we simply do
some parting to show that the results of the three groups are different. So
A is wrong.
B) This option is incorrect because there is only attempts information in

C) Compared with the other two groups, the humor group entered the
second phase of the "longer than who lasted" experiment, the longest

arrange for them to have a good night's sleep, so that the training will be
better? Lines 11 through 75 are detailing several experiments that
scientists have done to test this theoretical hypothesis, and lines 51 to 57

According to line 21 to line 29 of the article, the purpose of the experiment
is to compare the e-brain map of a dog who has learned something new
and then slept with the electro-encephalogram of a dog who has not
learned something new and then sleeps, to see if it is different, that is, to
see if learning before going to bed causes the dog to have some brain
activity during sleep. So choose D.

Although this question can be selected by exclusion, but we have to
thoroughly understand this question, but it is not easy. Let's look at the
problem first. First of all, the informed in the inscription is not an adjective,
but rather the dynamic of the object verb inform. And object verb form
means "giving characteristics or essence" (to give character or essence
to; give an essential or formative principle or quality to)
Example:
The relationship of the citizen to the state is informed by the democratic
ideal.
The identity of the country's citizens and the relationship between the
state is endowed by democratic ideas.
(The concept of democracy gives the citizens of this country the qualities
of the relationship between the state.) )
M

Second, look at another word in the question, which means "things to
consider; motivation, reason; factors" (a fact or a motive into account in
decisioning or judging something)
According to the article, it is reasonable to assume that thecharacteristics
of the experimental design of the Kis team's second experiment were
given by which of the following factors?
That is, "what makes the experimental design of the second experiment
have its characteristics(essence)".
We found the second experiment in the article, which is in lines 35 to 57,
and is talking about the experimental process of the second experiment.
The key to the experimental process of the second experiment (that is,
the key to the experimental design). It's about getting the dogs in the
experiment to learn the skills first (the formation of option A, the new
momory),divide the dogs into three groups, put a group of dogs to sleep,
a group of dogs to learnother skills, and a group of dogs to play with. This
ta
fa
means that three groups of dogs are allowed to perform three different
activities (i.e. beavior is modified) over a period of time frame after
learning the skill (i.e., in option A). It was this time frame that designed its
characteristics for the second experiment. The time frame in option A
means "especially when something has happened during a period of time
or as expected" (a period of time, especially a specific period of time in
what is what is planned to take place).
What the dog does in this time frame behavior determines the grouping
of dogs, and in the second test a week later, the performance of the three
groups of dogs is still compared by this group (lines 58 to 64).
So option A is correct.
It is added here that, according to the article, after the dog has initially
learned its skills, memory is formed, followed by sleep or other activities,
which are part of the process of being consolidation or forgetting.

Option B "Scientists have different views on what kind of brain activity

This passage is about how Ali trains soldiers and camels, and the

Two all grids cannot be connected, excluding AD. There should be an allin-one grid behind the experiment, because this means "the day of the

to the language, how I learned Orissa, why I taught English at the girls' college,
rM
but still insisted on learning Orissa. If she asked, I would have a lot to say, but she

from the author's memory. These experiences are not the author's, so the author's
r.
memory has never been, but Imagine only.
M

mother as they are to her.
The article does not compare who these experiences are more important to.
4.D。
The subject of the rhetorical purpose. Ask what the rhetorical features of lines 19

Line 19 to line 23 is to first say a translation version, and then the author's own
psychological activities, feel that the original sound (music) and the sound of the
ups and downs (lilt), in the translation is not reflected, and then changed to a new version of

novel. The author himself sees his own approach as...?

deflected shot), which does not apply here.
The team squandered several good scoring chances.

The subject of the rhetorical purpose. Ask about the rhetorical function of the last
M
natural segment. The main meaning of the last natural passage is "I didn't stop
until I found it was dark outside." That's when I found out that the landlord had
been turning on the TV volume until the maximum to watch the soap opera, and
I was so addicted to translation that I didn't know it. This is obviously to show how
much I am involved in translating. So pick C. Absorbed in option C means "input;
engrossed)。

of an individual, action, or event)"

M
try to pose. So pick C.
13.A。
Details. Ask the Bonawitz and Shulz teams to take steps to ensure that ...? It is common
to "exclude ... possible? "It's a different way of asking questions. Examine the
experimental design.
The evidence is on lines 23 to 26, and the first experiment is to get the kids to
swing the block, swing it in half, and not let them, so that the ideas they used to
bring (how to swing will balance) are not destroyed. That is, getting them to test
their own initial beliefs in the first task (or stage) of the experiment.

14.C。
Separate proof-seeking questions. Children are less likely to explore phenomena
us
that meet their expectations. Ask where the evidence is.
The evidence is on lines 44 through 50, and the who had their belief in line 48 is
rM
reversed and then the phenomena that conform to their expectations in the

M
The main purpose of this sentence is to draw the results of lines 41 to 55. Lines 12

that some bugs can walk on water, safely tiptoeing across the corresponding dry
M
r.
walk across.
25.A。
The subject of the rhetorical purpose. Ask the rhetorical function of the sentence
on lines 25 through 28. This sentence is mainly intended to explain the strange
word viscoelastic in line 25 in popular language. Viscoelastic means "flexible"
(having appreciable and conjoint viscous and elastic properties), which is learned in
physics that ordinary people generally don't know, so the author uses lines 25 to 28 to say
what Viscoelastic really means.
26.A。
The subject of the rhetorical purpose. It can be seen as a rhetorical function of
ta
fa
asking the fifth natural paragraph, or as asking what the full text of the focus has
gone from to.
us
Line 1 to line 28 is to introduce "the surface pressure of the liquid in the trap set
by the pig cage grass is low, so that the worm can not walk on its surface, can not
rM
climb out" such a scientific research object and topic (subject), line 34 to 52,
detailing David Armitage made an experiment on the subject. So choose A. Note

from prepared components。
So fabbricated and artificial mean close.

rM
A)N. The surface strength of the rafflesiana pig cage grass liquid is similar to that
of the California pig cage grass liquid. (Figure 1 does not have information
comparing the surface stress relationship between the two liquids, so A is wrong).
A

B) it has been shown to catch insects even when mixed with a relatively large
amount of water. (In Figure 1, if the horizontal coordinates are 1, 0.5, insects
cannot be captured.) So B error)
r.

Details. Ask what kind of person's point of view (perspective) is the author
Menchu's point of view based on the article? We can understand that this question
is asking, which of the following statements about the author is correct?
It does not state that the values of indigenous cultures are consistent with those

of non-indigenous cultures (so A is wrong), nor does it mention the author's
personal experience (so B is wrong), nor does it say that there is a preference for
us
indigenous previous customs (so C is wrong). The full text of the author uses us,
our, we in many places, indicating that the author's position is the same as that of
rM
the indigenous peoples. So choose D. "Think you have the same characteristics or ideas
as someone; think you're the same person as someone; identify with (someone) and empathy

the trunk, and the conquests for Humanity in line 26 corresponds to the progress
rM
of human civilization in the correct option.
38.A。
A
m
The subject of the rhetorical purpose. Ask lines 30 and 33, using three words, such
as discovery, what rhetorical features?
The equivalent of reusing discover three times, the repetitive function is often
r.
emphasized here that it is wrong to emphasize the use of the word discover, and
M
that it is wrong to say that Europeans discovered The Americas. The idea that
"Europeans discovered America" failed to recognize the level of complexity and
sophistication achieved by ancient American civilizations. So choose A.
The verb sophisticate corresponding to the correct option A means "make
(devices, technology, etc.) more complete (or complex advanced)" (develop
something such as a piece of equipment or a technique into a more complex form)
Some students wanted to choose option D, which said it was reused three times
to point out that the development of indigenous civilizations was a precursor to
European colonial action in the Americas.
Please note that precursor means a person or thing that comes before of the same
kind; a forerunner, so if it's a precursor, what happens before must be the same
ta
fa
thing as what happens later. The article does not say that the development of
indigenous civilizations in North America is similar to European colonial activities.
us
Also, to say three times is to emphasize that the word discover is wrong, that is,
rM
to point out a conception error. not to say that the two activities are similar.
39.B。
Details. According to the article, the author Menchu had some doubts and reservations
A
m
about "whether indigenous cultural heritage can contribute to modern civilization in the

According to lines 44 to 49 of the article, the author believes that for this kind of
r.
contention to be achieved, there must be a bassis, that is, a prerequisite, that is,
M
the right guarantees for equality between the Government and society,
corresponding to option B "pass a bill to ensure that the Government does not
have an uneconciable (excessive) authority over indigenous communities in the
country". (not...... disproportionate corresponds to equality).
40.B。
Separate proof-seeking questions. Menchu believes that this historic moment is a
positive moment for indigenous Peoples of North America to seek public recognition of
their cultural heritage.
The evidence is in lines 52 to 57, the test of the Fifth Centenary of the arrival of
the Columbus in America corresponding to the problem in the dry of the
highstorical moment, the 56th line of the reissert corresponding to the question
ta
fa

others recognize and know their rights (or rights) " (one's authority or a right) by
us
confidence and forceful behaviour, pay attention to the English interpretation of
rM
"recognize", so that resert can correspond to the public affirmation in the caption.
41.D。
The main topic of the article. This question actually requires us to summarize the

author Menchu.
Priority refers to what author Menchu thinks is a priority for indigenous people right

C) Sometimes it happens when the strength of the magnetic field does not change,

Two relationship questions.
A) Passage 1 describes one thing, and Passage 2 suggests a way to assess the
likelihood of this happening. (The second article is not about a way to assess the
likelihood of geomagnetic reversal, so A is wrong.) )
B) Passage 1 presents a theory, and Passage 2 criticizes a general
ta

misunderstanding of the theory. (B is wrong because there is no misunderstanding
of the theory.) )

C) Passage 1 describes some of the data, and Passage 2 questions the accuracy
of the data.

(The second article does not say that the data in the first article is inaccurate, so C
error)
D) Passage 1 gives an interpretation of the signs, and Passage 2 questions multiple

interpretations similar to this one. (The first article interprets the fact that
geomagnetic reversal may have occurred earlier than previously thought, and the
second article suggests that this interpretation is not necessarily correct, and that
M
r.
geomagnetic reversal may not have occurred earlier than previously thought.) ) 。
50.A。
Two relationship questions. Q. What is the most likely response to Passage 1's
hints on lines 34 to 37?
First we find lines 34 through 37 and see the hint that "geomagnetic reversal may
have occurred earlier than previously thought". Then we find Passage 2 lines 66
to 71, which say, "If the recent magnetic field strength is actually flat or above this
average strength compared to the average strength of the past 100 years; 6,000
years ago, for example, the magnetic field was 40% less intense than it is now, but
then, 5,900 years ago, 5,800 years ago, there was no reversal of the Earth's

magnetic poles. "So a new geomagnetic reversal may not happen any time soon.

Two relationship questions. Ask which of the following questions will the authors

of the two articles be disagree (that is, one will say yes, one will say no)?
Neither article mentions the consequences of the earth's magnetic pole reversal,
so A is wrong.
r.
Both articles agree that the frequency at which the Earth's magnetic pole reversal
M
occurs can be discerned (evidence is in lines 35 and 48), so B is wrong.
An estimate of the extent to which the Earth's overall magnetic field has weakened
(recently) is not considered exaggerated in the first article and exaggerated in the
second. So C is right.
The two articles did not mention that it would take a very long time to make a
reliable prediction. So D is wrong.

WRITING
Passage 1。
1.B。
The punctuation at the end of the sentence is determined by the main sentence,
ta
fa
the main sentence of this sentence is the statement order, so the end of the
sentence can not use a question mark, but should use a period, so exclude AD.
us
The order of the words from the sentence must be the order of the statement and
rM
not the order of the question, so B is not chosen C.
2.D。
Including is a preposition that needs to be used with a comma before it. Selecting

r.
Select the transition sentence. The last sentence mentions three systems, and the
M
last of the systems in C is very good to undertake above. What is said in ABD has
nothing to do with the last sentence.
4.A。
start down. Here's how scientists have known the math behind the turbulent flow
for a long time, but there have been no supercomputers to apply this theory to
solving real problems, and until recently petascale computers (millions of computers,
the power supercomputers needed by the people mentioned earlier) have only
recently become possible.
ta
fa
5.B。
The first half of the sentence is a while-guided concession clause, after the
us
sentence should be added a comma, and then take the main sentence, so choose
rM
B.
6.C。
Here so that guides a concession adverb clause. The whole sentence is that with
A

a model that can take advantage of billions of times of computer technology,
Chen and her team hope to improve the design of internal combustion engines
so that they are 50 percent more efficient than existing internal combustion
M
r.
engines.
7.C。
Word meaning analysis. The original text is meant to mean "current/current
internal combustion engine", so choose C. A prevailing is "universal and
prevalent", emphasizing the popularity of something over a period of time; D
surviving means "still alive, not dead", emphasizing that something is still alive.
8.B。
The title asks for the next sentence, so it needs to focus on understanding what
the next sentence means: she encourages young people, especially young women,
to study math and science, and computer programming languages. This
ta
fa
corresponds to the B option, Chen is a STEM advocate (that is, encouraging
us
people to learn STEM). The other options have little to do with the next sentence.
rM
9.A。
The principle of simplicity and the meaning are accurate. THE CD is too long and
not concise, but B's it will be unclear, which may lead the reader to understand
A

the previous language, so can only choose doing so, said "do this", the previous
only said one thing, that is, to encourage people to learn mathematics, science,
r.
programming language and other STEM subjects.
M
10.C。
The original sentence was about "making science a part of everyday life", so it
corresponded to C. Apart is "separated", a part is "part", every day is the noun
"every day", and everyday is the adjective "everyday, daily".
11.D。
The whole article is about Chen's use of high technology to improve the efficiency
of the internal combustion engine. Corresponding to D.

The main meaning is the same. The main language of this sentence is

The point of this sentence and this paragraph is to say that the information is
modified, a deviation from the facts.
16.A。
There's no need to leave behind the boundaries, because you don't need all the

Starting, this paragraph is mainly about the simple gaser fact can not show

m
The tense, which is speaking of The Decades before D'Agata, belongs to the "past

M
19.A。
Logical words. The previous sentence said truthfulness can be better expressed
by emphasizing individuals' subjectiveities (by emphasizing the subjective reality
of the individual, the truth can be better expressed), the latest sentence of the
Vietnam War is an example, the mainstream American media at that time there
was no emphasizing individuals' core realities, so missed the truth. The
relationship between the first and last two sentences is that the latter is an example
of the former.
20.C。
Compare the consistency of objects. The like attempt analogy in this sentence is
ta
fa
the task of creative nonfiction writers, the core word is task is not writers, so task
us
can only like task, task can not like writers, or those (people), can not worklike.

Passage 3。

Floating under the water's surface is the post-set adjective of the party, so the

This question examines the difference between qualified and non-qualified

more than strictly accurate descriptions.
Passage 4。
34.D。
Check to see if pronouns are unclear. There are a lot of song plumer nouns in
front of this sentence, which can't be referred to with they. This sentence is not
about stars, it's not about difficulties, it's about distance.
35.D。
Option D is the clearest expression of "this is the case" and the pronouns in ABC
ta
fa
are unclear.
us
36.B。
AC cannot be selected because there can be no colon or half sign between the
rM
clause clause and the previous modified noun. D cannot be selected because the
stars behind the punctuation are the namesobs of the previous stars, and the half
sign cannot be used between the preceding modified nouns, but should be used

The title requires repeating a detail from a previous sentence, note that it is not
us
the previous sentence, but from a previous sentence, so the information that is
repeat can be information in any of the previous sentences, then the previous
rM
reference to the two variable stars see equally bright, but one period is more than
the other. If the distance between the two earths is the same, then it makes sense
that the period of the two should be the same, and the two periods are not the
A
m
same degree of bright, so the article asks "So why do the stars see so similar?"
"(i.e. what do they see equally bright?) ), then the conclusion can only be The
r.
longer-period star must be farther away.
M
41.B。
Select the transition sentence. Option B accounts for the age when Levitt's
research was published, better to take on the next sentence of "One year later"
and further down "Now".
42.D。
For the first time is an insertion here, and the left and right should be separated
by a double comma.
43.D。
Here the adverb is not decorated with a previous noun, but a whole sentence, so
ta
fa
should use an unqualified clause clause, so you can not use a (because the that
can not guide the non-qualified clause from the sentence), but can only use which,
us
and the before the which can only be comma or dash, , so choose D.
