Colonial Williamsburg is a great place to visit. In
Williamsburg, you can see how people lived in colonial
times. There are guides in costumes who can show you to
taverns, shops, and houses. You can even sample some
colonial food at the restored taverns. One visit to
Williamsburg will make you feel as if you have been
transported to the 1700’s.

We’re often told “He who hesitates is lost,” but we’re also
warned to “look before you leap.” Most of us have heard the
saying, “Out of sight, out of mind,” but then we hear
‘Absence makes the heart grow fonder.” Everyone talks
about “love at first sight,” but then someone reminds us,
“Marry in haste, repent at leisure.” It’s all very confusing.
The United States calls its basic unit of currency the
“dollar”. Australia and New Zealand also measure their
currency by “dollars”. The money in Great Britain is called
the “pound”. Korea uses the ‘won”. In Russian you spend
“rubles”. Mexico and the Philippines use a ‘peso”. And the
country of Zaire calls its money unit a “Zaire”.

To make an educated guess based on incomplete
information or to “put two and two together.”
Tip 1: Read between the lines
Ex. April’s mother doesn’t come right out and say how she
feels about her daughter’s eyebrow ring, but she gives April
some pretty strong hints. She tells her daughter that the
new style is “very nice.” Then she rolls her eyes and smiles,
hoping that April will read between the lines.

How does April’s mother feel about April’s eyebrow ring?



A reasoned judgment that is made after all the available
information has been considered.

Unsupported inferences: wild guesses
Supported inferences: careful guesses based on known
facts.


Inferences are made based upon details and clues found in
the passages.

Tip 2: Making an inference requires detective work.


residents of Asheville, North Carolina, were embittered
against Thomas Wolfe during his lifetime.

realized the significance of their town on his writing.
Wolfe’s descendants still live in Asheville, and they
organized his birthday celebration in order to keep Wolfe’s
fame alive.

Tip 3: Support your inferences with information from the
passage.

A valid inference must be based on something in the
passage, such as details, the author’s tone, or other text
clues.
a.
b.
c.
d.
Aline Berstein was like Wolfe in being sensitive and
brooding and leading a turbulent life.

novelist whose work greatly influenced the young Wolfe.
Aline Berstein was the model for many of the heroines in
Wolfe’s autobiographical novels.
What clues from the passage support the inference you




Making predictions will help you keep your mind focused on
the passage and will help you better remember what you
read.
a.
b.
c.
d.
Wolfe’s personal life will become more important to
scholars than his novels.
Due to their length, fewer people in the digital age will
actually read all of Wolfe’s novels.
Research will show that Thomas Wolfe’s editors did most
of the writing of his books.
Wolfe’s style of writing, with its long meandering
sentences, will become the model for many young writers.

Tip 5: Add up details and inferences to draw conclusions.

Generalizations: putting specific details together to come up
with a general statement or principle that applies broadly.

“Drug abusers often start in upper elementary school. They
experiment with a parent’s beer and hard liquor and they
enjoy the buzz they receive. They keep doing this and it
starts taking more and more of the alcohol to get the same
level of buzz. As a result, the child turns to other forms of
stimulation including marijuana. Since these are the initial
steps that usually lead to more hardcore drugs such as
Angel Dust (PCP), heroin, and crack cocaine, marijuana and
alcohol are known as “gateway drugs.” Because of their
addictive nature, these gateway drugs lead many
youngsters who use them to the world of hardcore drugs.”
“The carrying capacity of a habitat refers to the amount of plant and
animal life its resources can hold. For example, if there are only 80
pounds of food available and there are animals that together need
more than 80 pounds of food to survive, one or more animals will
die – the habitat can’t ‘carry’ them. Humans have reduced many
habitats’ carrying capacity by imposing limiting factors that reduce
its carrying capacity such as housing development, road
construction, dams, pollution, fires, and acid rain. So that they can
maintain full carrying capacity in forest habitats, Congress has
enacted legislation that protects endangered habitats from human
development or impact. As a
result, these areas have high carrying capacities and an abundance
of plant and animal life.”
“Middle school gives students more autonomy than
elementary school. While students are asked to be
responsible for their learning in both levels, middle
school students have more pressure to follow through on
assignments on their own, rather than rely on adults. In
addition, narrative forms are used to teach most literacy skills
in elementary school. On the other hand, expository writing is
the way most information is given in middle school. “
“Astronomy came a long way in the 1500s and 1600s. In
1531, Halley’s Comet appeared and caused great panic. Just
twelve years later, however, Copernicus realized that the sun
was the center of the solar system, not the Earth, and
astronomy became a way to understand the natural world, not
something to fear. In the early part of the next century, Galileo
made the first observations with a new instrument – the
telescope. A generation later, Sir Isaac Newton invented the
reflecting telescope, a close cousin to
what we use today. Halley’s Comet returned in 1682 and it
was treated as a scientific wonder, studied by Edmund Halley.”
