Features of Writing in the text
1. When we read, we are not only learning new
vocabulary or structure , but also looking for key
information. Identifying keywords is even more
important if our reading time is not that plentiful.
“Lock” is the keyword in this text, by locating “lock”
throughout the text, we get a pretty good idea of
what this essay is about.
2. There are several examples of comparison and
contrast in this article: Para l vs. Para 4, Para l0 vs.
Para 1l, Para l2 vs. Para 13. The first pair acts as the
opening of the whole piece of writing. The latter two
are just two supporting details for the central
argument.
3. Other devices: It is interesting to see how the author
threads his narration back and forth between the past
and present. Never for once he does write “in the
past” or “at present” explicitly.
The writer has still cleverer devices at hand, like a
subtle tense change (e.g. simple past in Para. 1 vs.
present perfect in Para. 4), a phrase that indicate
an old habit in contrast with a phrase indicating
the current state (i.e. “used to” vs. “no longer” in
Para. 11), or a summary sentence ( It wasn’t
always like that” in Para.12).

Assignment
Directions: For this part, you are allowed 30 minutes to
write a short essay on the topic Campus Security. You
should write at least 120 words, and base your
composition on the outline (given in Chinese) below:
1)近年来发生在校园的意外事件不断增加，校园安
全问题备受关注
2)对此我们应该采取哪些措施
Campus Security
Security issue may sound clichéd, but when it
comes to the campus security, we have to take it
seriously. Nearly every day, there are reports to the
security office on campus that valuable things are stolen
away. A surrounding with stealing, mugging can’t be
worse for studying. In such cases, what measures should
be taken to improve the campus security?
On the one hand, we students should strengthen our
security awareness. Once we smell out something
unusual, we should report it to the campus guard
immediately.
On the other hand, more equipment such as monitors
should be installed on campus so as to detect crimes as
soon as possible. Besides, a proper amount of security
guards should be arranged to patrol the campus.
In my opinion, campus security will be improved
as long as efforts are made on campus. Therefore
colleges and universities should try their best to make
everyone on campus safe and sound.

II. Translation
A burglary is reported every 15 seconds in the United States.
Statistics show burglars entered more than 2 million homes
last year. Actually it is almost impossible to keep a
determined burglar out. All you can do is discourage him
for a few minutes, thus exposing him to police patrols or
those wandering around. Common sense tells us that
lighting is a barrier to criminal activity. A light should be
fixed in the doorway and switched on at night.
Believe it or not, some people, particularly children who
happen to be the last to come in, leave their doors on the
latch at night. Doors of hollow core, even when locked, are
vulnerable to break-ins. Thus doors of solid core or steel are
much preferred as they make it difficult for the burglar to
pry open. If you decide to buy an alarm device, be sure to
ask for its signs and put them up on both windows and
doors. Finally, a word of warning—when you travel, make
sure that you have a trusted neighbor collect and keep all
the deliveries of newspapers and mail until you return. This
is because a collection of newspapers and mail on the front
doorstep or in your mailbox is an advertisement that no one
is home.
Thanks for your attention
