Part Ⅱ Reading Comprehension (35 minutes)

　　Questions 21 to 25 are based on the following passage:

　　Some radio singals were heard in 1967.They were coming from a point in the sky where there was unknown star.They were coming very regularly,too:about once a second,if they were controlled by clock.

　　The scientists who heard the signals did not tell anybody else.They were rather afraid to tell in case they frightened people.The signals were coming from a very small body—no bigger,perhaps than the earth.Was that why no light could be seen from it?Or were the signals coming from a planet that belonged to some other star?There was no end to the questions,but the scientists kept the news secret.“Perhaps there are intelligent beings out there.”they thought,“who are trying to send messages to other planets,or to us?So the news was not given to the newspaper.Instead,the scientists studied the signals and searched for others like them...Well,all that happened in 1967 and 1968.Since then scientists have learnt more about those strange,regular,radio signals.And they have told the story,of course.

　　The signals do not come from a planet;they come from a new kind of star called a “pulsar””.About a hundred other pulsars have now been found,and most of them　are very like the first one.

　　Pulsars are strong radio stars.They are the smallest but the heaviest stars we know at present.A handful of pulsar would weigh a few thousand tons.Their light—if they give much light—is too small for us to see.But we can be sure of this,no intelligent beings are living on them.

　　21. The radio signals discussed in this passage____.

　　Questions 31 to 35 are based on the following passage:

　　Telephone, television, radio, and telegraph all help people communicate with　each other. Because of these devices, ideas and news of events spread quickly all　over the world. For example, within seconds, people can know the results of an　election in another country. An international football match comes into the homes　of everyone with a television set.News of a disaster such as an earthquake or a　flood can bring help from distant countries within hours, help is on the way. Because of modern technology like the satellites that travel around the world, information travels fast.

　　How has this speed of communication changed the world? To many people,the world has become smaller. Of course this does not mean that the world is actually physically smaller. It means that the world seems smaller. Two hundred years ago,communication between the continents took a long time. All news was carried on ships that took weeks or even months to cross the ocean. In the seventeenth and eighteenth centuries,it took six weeks for news from Europe to reach America.This time difference influenced people's actions. For example, one battle, or fight, in the War of 1812 between England and the United States could have been avoided. A peace agreement had already been signed. Peace was made in England, but the news of peace took six weeks to reach America. During these six weeks, the large and serious Battle of New Orleans was fought. Many people lost their lives after a peace treaty had been signed.They would not have died if news had come in time.In the past,communication took much time than it does now.

　　There was a good reason why the world seemed so much larger than it does today.

　　31. News spreads fast because of____.

　　A.modern transportation B.new technology

　　C.the change of the world D.a peace agreement

　　32. According to this passage,____is very important to people in a disaster area.

　　B.The world is actually smaller today.

　　C.The world is changing its size.

　　D. The distance between England and America has changed since the War of 1812

　　34. Two hundred years ago,news between the continents was carried____.

　　A.by telephone and telegraph B.by land

　　C.by air D.by sea

　　35. The New Orleans Battle could have been avoided if the peace agreement had been signed____.

　　A.by both sides B.in time

　　C.in America D.in England

　　Questions 36 to 40 are based on the following passage:

　　The concept of personal choice in relation to health behaviors is an important one.An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choices based upon current medical knowledge.

　　We all enjoy our freedom of choice and do not like to see it restricted when it is within the legal and moral boundaries of society.[ZZ)]The structure of American society allows us to make almost all our own personal decisions that may concern our health.If we so desire,we can smoke,drink excessively, refuse to wear seat　belts,eat whatever foods we want,and live a completely sedentary life-style without any excuse.The freedom to make such personal decisions is a fundamental aspect of our society,although the wisdom of these decisions can be questioned.Personal choices relative to health often cause a difficulty.As one example,a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do. A multitude of factors,both inherited and environmental,influence the development of heal threlated behaviors,and it is beyond the scope of this text to discuss all these factors as they may affect any given individual.However,the decision to adopt a particular health-related behavior is usually one of personal choices.

　　There are healthy choices and there are unhealthy choices.In discussing the moral of personal choice,Fries and Crapo drew a comparison.[ZZ(Z]They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide.[ZZ)]Thus,for those individuals　who are interested in preserving both the quality and quantity of life,personal health choices should reflect those behaviors that are associated with statistical probability of increased vitality and longevity.

　　36. The concept of personal choice concerning health is important because____.

　　A.personal health choices help cure most illnesses

　　B.it helps raise the level of our medical knowledge

　　C.it is essential to personal freedom in American society

　　D.wrong decisions could head to poor health

　　37. To “live a completely sedentary life style”(Para. 1) in the passage means____.”

　　A.to live an inactive life B.to live a decent life

　　C.to live a life with complete freedom

　　D.to live a life of vice

　　38. Sound personal health choice is often difficult to make because____.

　　A.current medical knowledge is still insufficient

　　B.there are many factors influencing our decisions

　　C.few people are willing to trade the quality of life for longevity

　　D.people are usually influenced by the behavior of their friends

　　39. To knowingly allow oneself to pursue unhealthy habits is compared by Fries and Crapo to____.

　　A.improving the quality of one's life

　　B.limiting one's personal health choice

　　C.deliberately ending one's life
