　　Part Ⅱ Reading Comprehension (35 minutes)
　　Directions: There are 4 passages in this part.Each passage is followed by so
　　me questions or unfinished statements.For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding
　　letter on the Answer Sheet with a single line through the center.
　　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.

　　Questions 26 to 30 are based on the following passage:
　　Over vast areas of every continent,the rainfall and vegetation necessary for life are disappearing.Already more than 40 percent of the earth's land is desert or　desert瞝ike.About 628 million people—one out of seven—live in these dry regions.In the past,they have managed to survive,but with difficulty.[ZZ(Z]Now largely through problems caused by modern life,their existence is threatened by the slow,steady spread of the earth's deserts.
　　Scientists still do not understand all the complex problems of the desert,but there have been many ideas for saving the land.Sandi Arabia has planted 10 million　trees to help keep the sand from taking over fertile areas.The Israelis are again using some of the water collection systems left by the ancient people in the
　　Negev desert.They plan to water their orchards with the extra water.Some Sahel farmers still raise cattle on their poor farm land,but before the cattle are sold,　they are taken to greener lands in the south to get fat.

　　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.
　　A.fast communication B.modern technology
　　C.latest news D.new ideas
　　33. Which of the following statements is true?
　　A.The world now seems smaller because of faster communication.
　　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

　　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 health瞨elated 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瞫tyle”(Para. 1) in the passage means____.”
　　A.to live an inactive lifeB.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
　　D.breaking the rules of social behavior
　　40. According to Fries and Crapo sound health choices should be based on____.
　　A.personal decisions B.laws of society

　　Part Ⅴ 写作指导
　　这是一篇议论文，要求根据提纲来展开论述。论述时应层次分明，先论述生活中缺少不了朋友，然后再论述什么才是真正的朋友，并在此基础上阐明自己交友的原则。ニ孀派缁岬姆⒄梗社会节奏的加快，人与人之间的关系反而淡漠了。每个人身上都或多或少反映着某种心理疾病，人们渴望交友。在范文中，第一段先阐明在社会交往中离不开朋友，再分别从两个方面指出遇到困难时可以从朋友那儿得到帮助;高兴，娱乐时可以和朋友分享。通过 first,secondly加强文章的逻辑性。第二段在论述什么是真正朋友时引用成语“患难见真交”，使其更具说服力。最后一段表明自己的交友态度，总结全文。
　　Writing Sample
　　As a human being,one can hardly do without a friend.Society is made up of individuals,and making friends is a very important part in our life.Friends can give you a lot.First,if you have trouble with some problems,you can consult your good　friends and exchange opinions.Thus,you will feel comfortable and encouraged.Secondly,if you wish to do some physical exercises,such as playing table tennis,you could play with friends and have a good time.
　　But what is true friendship?Some people think friends are people whom they can play with.In my opinion,a friend in need is a friend indeed.True friendship can encourage you when you are in difficulties.A true friend not only shares with you
　　your joy and happiness but also your trouble and anxiety.When you need him,he　will give you a hand and spare no efforts.
　　As far as I'm concerned,I wish to make as many friends as possible.The world is　a big family,and we will feel relaxed in a friendly atmosphere.I wish some day we can all be friends.
