Werewolves (狼人) aren’t the only creatures(生物) affected by the moon’s cycles. A full moon slightly affects people’s sleep, reports a Swiss team of scientists. Even people’s sleep in a lab without windows experienced a small shortfall in sleep once a month.
To test the moon’s effect, 33 adult volunteers of both sexes and various ages spent several nights in a sleep lab. As they slept, researchers recorded their brain activity, eye movements and hormone (荷尔蒙) levels. On nights closer to a full moon, the subjects took an average of five minutes longer to fall asleep, and slept for 20 minutes less. In addition, brain activity decreased by 30 percent during the sleep stage that the brain normally uses to recover from its daylight work. And levels of hormone that help control sleep cycles dropped. On these nights, the sleepers complained of poor sleep quality even though they were unaware of the moon’s cycle. On the bright side, not a single participant turned into a werewolf.
The Swiss team doesn’t know how the moon affects sleep. The gravity (重力) of the moon causes ocean tides to rise and fall. But that force is too weak to affect sleep, Gajochen says. He believed some body’s biological clock may be tied to the moon cycles. There may be another explanation, says David Dinges. This sleep researcher at the University Of Pennsylvania in Philadelphia says that the body clock is very sensitive to light at night. Volunteer’s sleep could have been affected by exposure to extra moonlight before arriving at the lab.
The writer mentioned “werewolves” in the first paragraph to ______.

A．prove that the moon’s cycles exist

B．draw people’s attention to the report

C．introduce a similar creature to readers

D．warn people not to sleep alone in the lab

What happened to the volunteers during the experiment on a full moon?

A．They slept for about five minutes longer.

B．Their brains never recovered from their work.

C．They complained they were too tired to sleep.

D．Their brains were not so active as they were

The last paragraph is developed mainly by ______.

A．analyzing causes	B．explaining differences
C．making comparisons	D．following the time order

The passage is mainly about ______.

A．the sleeping problems caused by the moon’s cycles

B．the influence of the moon on human sleeping habits

C．the moon’s effect on sleeping and its possible reasons

D．the ways to improve sleep quality on a full moon night

More than 20,000 drivers and front seat passengers are killed or seriously injured each year. At a speed of only 30 miles per hour it is the same as falling from a third floor window. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.
Therefore drivers or front seat passengers over 14 most vehicles must wear a seat belt. If you do not, you could be fined up to $50. It will not be up to the drivers to make sure you wear your belt. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.
However, you do not have to wear a seat belt if you are reversing(倒退) your vehicle; or you are making a local delivery or collection using a special vehicle; or if you have a valid（正当的） medical certificate（证书）which excuses you from wearing it. Make sure these cases supply to you before you decide not to wear your seat belt. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court you have been excused from wearing.
60. This passage is probably taken from ______.
A. medical magazine    B. a legal document
C. a textbook    D. a government information booklet
61. Wearing a seat belt in a vehicle ______.
A. reduces road accidents by more than half
B. reduces the death rate in traffic accidents
C. saves lives while driving at a speed up to 30 miles per hour
D. saves more than 16,000 lives each year
62. It is the driver’s responsibility to ______.
A. make the front seat passenger wear a seat belt
B. make the front seat children under 14 wear a seat belt
C. stop children from riding in the front seat
D. wear a seat belt each time he drives
63. For some people, it may be better to ______.
A. pay a fine rather than wear a seat belt
B. wear a seat belt for health reasons
C. (not to) wear seat belt for health reasons
D. get a valid medical certificate before wearing a seat belt

第三部分：阅读理解（共20题；每小题2分，共40分）
阅读下列短文，从每题中所给的A、B、C、D四个选项中，选出最佳选项。
You have heard the expression “horse sense”. As you may imagine, it came from the time when the majority of people traveled in vehicles drawn by horses. A horse does have a lot of common sense, and there are many true stories about horses having saved their drivers from danger of death.
Today for the most part, people travel by train, ship, airplane, and car, but very little by the use of horses. Modern vehicles are propelled by engines, and an engine does not have any sense. In case of danger, many horses could be depended on to help. Not so with the engine; the driver must do all the things.
In recent years, the speed of travel has increased greatly. With the increased speed comes greatly increased danger. The driver of a powerful engine needs to be careful. A moment of being careless may cost a life. In order to drive today, a person must be able to see clearly, and he must learn and follow carefully the rules for safety on the road. Greater attention is the price we pay for using a machine instead of a horse.
56. The passage mainly talks about ______.
A. engines B. safe driving C. using horses D. modern machines
57. The underlined word “propel” in the second paragraph means ______.
A. repair B. raise C. push forward D. made
58. It can be inferred from the passage that ______.
A. a driver must know the rules of safety
B. a driver needs to be able only to tell red from green
C. an eye test is an important part of a driver’s examination
D. greater attention is needed for a driver while driving a machine
59. Which of the following is NOT true?
A. A driver must be able to see and hear well.
B. The driver of a car must follow the rules of safety.
C. Horses are known to have saved their drivers from injury.
D. It is better for vehicles to be pulled by horse than to be pushed by engine.

Do you suppose Darwin, one of the greatest scientists of all times, really
did fools' experiments?
Or did he do experiments that were so simple and basic that other people just thought they were foolish?
Sometimes people think they already know the answer to a question or the solution (解决办法) to a problem. Sometimes they really do know an answer or a solution, but without thinking they are important.
Charles Darwin didn’t settle for (满足于) just thinking he knew something. And, he believed all things could be important however simple they seemed to be.
Suppose you drop two sheets of paper which are exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheet. What happens? You have done an experiment that is so simple that you might think it couldn't be worth anything.
But this simple experiment is important. It explains part of our present-day understanding of physics ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.
Science sometimes stops to look at very simple things and to think very hard about them. Even the simplest idea, what we might think is foolish, can shake the foundations (基础) of science.
68. “Sometimes people think they already know the answer to a question.” This means that _________.
A. they are already told the answer
B. the question is so important that everyone should know the answer
C. they are already to answer such a question by others
D. the question is simple enough for them to answer
69. From the passage, we learn that Charles Darwin _________.
A. did many fools' experiments
B. enjoyed doing simple experiments
C. was not satisfied with what he knew
D. tried to prove that Galileo and Newton were sometimes wrong
70. The underlined phrase “set aside” most probably means “________”
A. throw away B. store up B. put to use D. realize
71. The author of the passage tries to ________.
A. convince(使…信服) us that Charles Darwin, Galileo and Newton are the greatest scientists in the world
B. draw the conclusion that basic sciences are simple things
C. prove that two sheets of paper, with the same size and shape, will fall at the same speed
D. draw our attention to everyday happenings around us

An epidemic (流行病) of the use of street-culture language broke out in some English exams, according to examiners.
A report said there were “a surprising number of small mistakes” in standard (标准) English. It asked teachers that they should prevent pupils from using "street language and text style", adding, “Most answers require formal expression of language.”
“Many concerns were expressed by examiners about basic errors, often appearing in the work of clearly able students,” the report continued.
It added that the use of street and text language “appeared with surprisingly regularity in the work of students who clearly desired a higher grade”.
“Most answers require formal expression but even when an informal style is appropriate--students should know the examination context and, in particular, should not use street language and text style.” it said.
There is rising concern about pupils’ writing skills, especially among boys. National test results for 11-year-old boys’ writing standards had fallen this year. Only 55 percent reached the level expected of an 1l-year-old by the time they left primary school, the results showed.
Many educationalists are now arguing that teachers should also think of ways of improving writing standards.
The report said spelling was “in general inconsistent(不一致)” and “variety of vocabulary and of sentence structure is often limited”. It went on, “Punctuation (标点符号) errors continue to be widespread.”
However, it added, “Some examiners felt that this year they had met an improvement in the whole structure of students' writing.”
64. What does the passage mainly talk about?
A. Street language is appearing in the standard English exams.
B. What the street-culture language is in England.
C. The English say no to the street-culture language in daily life.
D. The street-culture language is being examined in English exams.
65. The underlined word “appropriate” (in Paragraph 5) means “ _______”
A. available             B. possible             C. valuable                   D. acceptable
66. What problems concerned examiners ?
A. Small mistakes in spelling and punctuation,
B. Poor sentence structure, and errors in spelling and standard English.
C. Teachers teaching writing skills.
D. Limited vocabulary of boy pupils.
67. According to the passage, which of the following statements is TRUE?
A. In English exams, most answers require informal expression of language.
B. When an informal style is correct, the students are allowed to use it.
C. Boys' writing skills are worse than those of girls in England.
D. There is no improvement in the whole structure of students' writing.

On the wall in my mother’s bedroom there was a photo, which showed a soldier with a gun.
