　　Men usually want to have their own way.They want to think and act as they like.No one,however,can have his own way all the time.A man cannot live in society without considering the interests of others as well as his own interests."Society" means a group of people with the same laws and the same way of life People in society may make their own decisions,but these decisions ought not to be unjust or harmful to others.One man's decisions may so easily harm another person.For example,a motorist may be in a hurry to get to a friend's house.He sets out,driving at full speed like a competitor in a motor race.There are other vehicles and also pedestrians（步行者) on the road.Suddenly there is a crash.There are screams and confusion.One careless motorist has struck another car.The collision has injured two of the passengers and killed the third.Too many road accidents happen through the thoughtlessness of selfish drivers.
　　We have governments,the police and the law courts to prevent or to punish such criminal acts.But in addition,all men ought to observe certain rules of conduct.Every man ought to behave with consideration for other men.He ought not to steal,cheat,or destroy the property of others.There is no place of this sort of behavior in a civilized society.

　　Fever has usually been regarded as a threat to health.However,no one has actually proved that fever is dangerous.This fact attracted the attention of Matthew J.Kluger.Imagining that fever might not be as harmful as it had been supposed,Kluger set up a series of experiments with lizards(蜥蜴).

　　What Kluger and his team did his team did in their first experiment was simple.They put some lizards in a sand-box,one end of which was heated to 44℃,while the other was at a room temperature.It was found that the lizards moved form one part of the box to the other in order to keep a constant temperature of about 38℃.Having shown that normal lizards regulate(调节) their own temperature,Kuger,in a second experiment,then set out to show that lizards,like most other animals,develop fever when infected.This was done by making lizards infected with bacteria (细菌) that were known to cause disease.As the team expected,the infected lizards remained longer in the heated part of the box,until they had raised their body temperatures to two or three degrees above normal.In other words,the sick lizards gave themselves fever.

　　In a third experiment,the team observed the effect of temperature on the survival of the lizards.One group of infected lizards was given a fever - suppressing(退烧) drug.The other group was given no drug and ran a fever,that is to say,they kept a highter temperature for four or five days before seeking a cooler environment.The results were impressive.Of those which raised their body temperature,all but one remained alive.Of those given the fever - suppressing drug,more than half died.Similar results have since been produced in other animals.For example,infeced fish swim to warmer water,and will die if not allowed to do so.

　　An important conclusion can be drawn from these experiments.As Kluger points out,lizards have been on earth for hundreds of millions of years.It is reasonable to suppose that a response that is so old has been kept by nature for some purpose.It would appear, therefore, that fever does not make disease worse.Rather it its part of the mechanism(机能) by which infection is controlled.

　　60.In his experiments,Kluger was hoping to prove that fever ________.

　　　A.is not harmful to lizards

　　　B.is not necessarily bad

　　　C.is necessary for both humans and animals

　　　D.has the same effect on humans and animals

　　61.The lizards put in the sand - box in the first experiment _____.

　　　A.had a fever B.were not sick C.recovered from disease D.died of heat

　　62.In the third experiment,the lizards given a fever - suppressing drug died because _____.

　　　A.they had no more fever that they needed

　　　B.they were normal ones and had no fever

　　　C.the drug had no iffect on sick lizards

　　　D.the drug made their body temperature too low

　　63.How would you understand the underlined words"a response" in the last paragraph?

　　　A.Gause of disease. B.Recovery from disease.

　　　C.Relationship between living D.Natural defense in the body against disease.

Miss Gorgers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from the street, which of you would hear what I said earlier, my brother or you and for what reason?”
Tom at once answered, “Your brother. Because electricity travels faster than sound waves.” “That’s very good,” Miss Gorgers answered; but then one of the girls raised her hand, and Miss Gorgers said, “Yes? Kate.”
“I disagree. Your brother would hear you earlier because when it’s 11 o’clock here and it’s only 8 o’clock in Los Angeles.” Kate said.
1. Miss Gorgers was teaching her class ______.
A. how to telephone      B. about electricity

阅读下列短文, 从每题所给的选项（A、B、C和D）中，选出最佳选项，并在答题卷上将该项涂黑。

B 

　Two experts did some experiments on two groups of people — one who tended to sleep less than the

people around them and the other group more.

According to their report that the “short sleepers” had been more or less average in their sleep needs until the men were in their teens. But at about age 15 or so, the men automatically began to cut down their nightly sleep time because of pressures from school, work, and other activities. These men tended to view their nightly periods of unconsciousness as bothersome interruptions in their daily routines.

　　 In general, these “short sleepers” appeared with ambition, active, energetic, cheerful, and conformist (不动摇) in their opinions, and very sure about their career choices. They often held several jobs at once, or even worked full time while going to school. And many of them had a strong urge to appear “acceptable” or “outstanding” to their friends and associates.

　　When asked to recall their dreams, the “short sleepers” did poorly. More than this, they seemed to prefer not remembering them. In similar fashion, their usual way of dealing with psychological problems was to deny that the problem existed, and then to keep busy in the hope that the trouble would go away.

　　The experts also stated that those “long sleepers” were quite different indeed. They reported that those men had been lengthy sleeps since childhood. They seemed to enjoy their sleep, protected it, and were a bit concerned when they were occasionally deprived of their desired 9 hours of nightly bed rest. They tended to recall their dreams much better than the “short sleepers did.

　　Many of the “long sleepers” were shy, anxious, introverted (内向), inhibited (压抑), passive, mildly depressed, and unsure of themselves (particularly in social situations). Several openly express it that being asleep was a good escape from their daily problems.

All in all, proper time of sleeping should be admired, not too long, neither too short.

According to the report, ______.

　 A. many “short sleepers” need less sleep just by nature

　 B. many “short sleepers” are obliged to reduce sleep time by work

　 C. long sleepers sleep a longer period of time during the day

　 D. many “long sleepers” formed sleeping habit during childhood

Many “short sleepers” are likely to hold the view that ______.

　 A. sleep is a very efficient escape from the reality

　 B. sleep is just an item which should be denied by them

   C. sleep might be a disturbing thing for their daily business

　 D. sleep is the best way to deal with psychological troubles

It is stated in the forth paragraph that “short sleepers” ______.

　 A. are ideally energetic under the pressures of life

　 B. often ignore the ill effect of not enough sleep

　 C. do not know how to relax themselves properly

　 D. are more unlikely to run into mental problems

Which of the following is nearest to the meaning of “… were a bit concerned ” in the fifth Para?

　 A. appeared troubled                     B. became energetic

C. felt dissatisfied                       D. were much depressed

Which of the following is NOT correct according to the passage?

　 A. If one sleeps improperly, his performance suffers and his memory is weakened

　 B. The sleep patterns of short sleepers are the same as those shown by “long sleepers”

　 C. Long and short sleepers differ in their attitudes towards sleep

　 D. Short sleepers may have been better off if they have more rest
