第三部分阅读理解(共20小题；每小题2分，满分40分)
阅读下列短文，从每题所给的四个选项(A、B、C、D)中，选出最佳选项。
A
I
don't think there is anything wrong with your blood .The key to your problem is
that long nap after dinner .If you didn't sleep for hours during the early part
of the evening ,you would be more ready to sleep at bedtime .If you didn't nap
after dinner ,you would not want to stay up so late ,and you would not feel the
need to take a sleeping pill .The pill is still working in your system when you
get up in the morning .This helps account for the fact that you feel tired all
day .You should get out of the habit of sleeping during .Right after your
evening meal ,engage in some sort of physical activity ---a sport such as
bowling ,perhaps or get together with friends for an evening of cards and
conversation .Then go to bed at your usual time or a little earlier ,and you
should be able to get a good night’s rest without taking a pill .
If
you can get into the habit of spending your evenings this way ,I am sure you
will feel less tired during the day .At first it may be hard for you to go
sleep without taking a pill .If so ,get up and watch television or do some jobs
around your house until you feel sleepy.If you fall asleep and then wake up a
few hours later ,get up but do not take a sleeping pill .Read a while or listen
to the radio ,and make yourself a few hours’ sleep that night, you will feel
better in the morning than you usually feel afterv taking a pill.The next night
you will be ready to sleep at an earlier hour .
The
most important thing is to avoid taking that nap right after dinner and avoid
taking pills .

If
you do not know what to wear to attend a Chinese celebration, something red is
always the right choice on such occasions. The red color is always associated
with "happiness and good fortune" . The Chinese people enjoy
decorating their houses with something red. The bride wears a traditional
Chinese wedding dress in red on her wedding day (though probably influenced by
the western customs she would wear white wedding dress at the beginning of the
celebration). Unlike the implication of red to anger, danger and the
unreasonable outburst of emotions in the West, such as the expressions like: be
a red rag to a bull; to see red; to see the red light; to paint the town red;
red in tooth and claw etc. the red always carries positive meanings in China.
The next
color used to be very special is yellow, which is similar to the color of earth
and soil since earth and soil were very important to people. Yellow used to be
the fashionable color used by the Emperors in
Another favorite color is green, which represents life and energy, while black and white are associated with death. Don't wear a black dress to attend the wedding or a birthday party. Wearing white headdress (头饰) indicates that someone in your home recently dies.
Probably black is also associated with darkness. The Chinese like to refer to things illegally done "black", for example, "black money" and "black market". And "black heart" refers to someone really bad.
The indirect meanings of colors are obvious in the costumes of traditional Chinese operas. Red indicates loyalty and courage; black represents honesty and fairness; yellow clothing signifies royalty and white to purity.
Don't
wear a green hat on any occasion in your daily life. "Wearing a green
hat" is a Chinese idiom referring to one's wife has committed adultery. A
husband wearing a green hat seems to claim that his wife is an adulteress.
Therefore don't make yourself a standing joke.
61. Compared with that in the West, red color in
A. anger B. danger C. justice D. luck
62. Which of the following is TRUE?
A. White has a positive meaning in Chinese opera.
B. Yellow used to be fashionable among working people.
C. Red was a major color usually used by the Emperor.
D. Green is a color always carrying a negative meaning.
63.People wearing ____ are welcomed in a birthday party.
A. a black suit B. a white headdress C. a. red dress D. a green hat
64. The article is written to tell us mainly about____.
A. the different categories of colors B. the cultural meanings of colors
C. the historical development of colors D. the history of color concepts
C
“Keep your eyes on the ball.” That is good advice when you are on the playing field, and good advice for everyday life. “Keep your mind on what’s important,” is the way I’d put it. But people are funny.They think too much about the details.
I had a secretary
once. She was very hardworking. I ran a school and people used to call up to
enroll for courses.
People just don’t see the big picture. One evening, after leaving work, I was sitting next to a man on the train. I was feeling tired. My eyes fell on the paper spread out in front of him. You know how you feel to read over someone’s shoulder?
I read the page and leaned back. I guessed I was waiting for him to turn it. After a while, I realized―he wasn’t turning the page. He just kept on reading.
Now if you knew the rag he was reading, you’d know that there weren’t many words on the page to read anyway. The layout was mostly pictures. So I turned to the man and said,” You know, you really read very slowly.”
“What do you mean ?” he asked. “Well,” I told him, “I read the page in about a minute, and you have taken about ten. And you are still reading. You know,” I went on “If you learned to read faster, you could get more reading done.” He remained silent for a minute or two. “If I read too fast, my paper wouldn’t last me to my station.”
65. What did the secretary think of the students calling up to enroll?
A．She thought they needed her help.
B．She thought getting more students enrolled was more important.
C．She thought her work was more important.
D．She thought her boss needed her typing finished soon.
66. The writer wasn’t satisfied with his secretary because ___.
A．she didn’t put first thing first B．she was too busy
C．she was easy to get angry D．she couldn’t finish her work on time
67. The train rider read newspaper ___.
A．to absorb information B. to enjoy pictures C. to save time D. to kill time
68. The writer thinks that people seem to need a sense of ___.
A．what to read first B. how to read fast C. what is important D. what is funny
D
In the U．S．，the public has tended to believe that all motorcycles are ridden by wild，irresponsible lawless young men．
There are several things about
motorcycling that the average citizen dislikes．A cyclist’s appearance has something to do with this dislike．Motorcyclists frequently look dirty；in fact，they are dirt
y．On the road there is little to protect them
from mud，crushed
insects and bird droppings．For practical reasons they often dress in old clothing which looks much
less respectable than the clothing of people who ride in cars．For the same reason motorcyclists usually
wear dark colors．Perhaps
this helps to explain why they are sometimes suspected of having evil natures．In old plays of long ago，evil characters usually wore black．In cowboy movies the“bad guys”usually wear
black hats while the“good guys”wear lighter colors．Something else about their appearance makes
an unfavorable impression．In their practical，protective clothing they look very much like the men on military
motorcycles in the movies of World War II―cruel enemies who roared into
peaceful villages filling people’s hearts with fear．
Probably the machine itself also produces anger and fear．Motorcycles are noisy，though some big trucks are even noisier．But trucks are big and carry heavy loads；they are accepted(if not really welcomed)because they perform a needed service，making America move．Motorcycles，on the other hand，make all unpleasant noise just to give their riders pleasure．That is what is commonly thought．In the woods motorcycles frighten animals．Roaring along quiet streets，they wake sleeping families and make babies cry．
Of course the danger of motorcycling also helps account for many people’s low opinion of the sport．Its defenders，however，claim that careful cyclists are in less danger than commonly believed．
A cyclist must drive as if everybody around him wanted to kill him．He must pay careful attention to his driving．From that point of view．a man on a motorcycle is safer than a man in a car．
69．According to the passage．the average Americans believe that ___________.
A．motorcyclists are all blue―collar workers
B．motorcycling has become one of
C．only wild，irresponsible，lawless young men enjoy motorcycling
D．motorcyclists can’t afford to buy cars
70．From the passage we know that good characters of old American movies_______________.
A．usually wore lighter colors B．had no difference from evil characters
C．1ooked gracious D．often rode horses
71．It can be inferred that ________.
A．there existed different opinions towards motorcycling sport
B．all good guys in cowboy movies wear white
C．animals in the woods like motorcycles because motorcyclists usually feed crushed insects to hem
D．motorcycles will make noise as soon as people go to sleep
72．Some people claim that a man on a motorcycle is safer than a man in a car because _____________.
A．car race is a sport with several disadvantages
B．motorcyclists must drive very carefully
C．most people want to keep a distance from the dirty motorcycles for fear that they should lose dignity
D．motorcycles tend to be accepted by more and more people

VI.书面表达
One possible version:
Nowadays more and more students are found to cheat in the exams. Reasons may vary from person to person; anyway, they can be generalized as follows:
To begin with, with endless examinations flooding in, some students may have difficulty working them out. Also, some students are too lazy to focus their attention on their study. Besides, others cheat for high scores to please their parents and teachers.
Personally, I think it wrong to cheat in the exams in that for one thing, it goes against / breaks the rules of schools; for another, it’ll result in the crisis of one’s honesty. Therefore, we should devote ourselves to study and try to make progress with our own efforts.
