　　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____.

　　A.were regular B.were controlled by a clock

　　C.were heard in 1967 only D.were secret messages

　　22. The radio singals were sent by____.

　　A.a satelliteB.a planet

　　C.a sky body which was unknown at that time

　　D.intelligent beings who were unknown at that time

　　23. The scientists did not tell people about the signals because____.

　　A.the singals stood for secret messages

　　B.people would ask them too many questions

　　C.they did not want to frighten people

　　D.they stood for unimportant messages

　　24. A pulsar is____.

　　A. a small heavy star which sends out strong radio signals and cannot be seen

　　B. a small heavy planet which sends out strong radio signals and cannot be seen

　　C. a small heavy satellite which sends out strong radio signals and cannot be seen

　　D. a small intelligent being who sends out strong radio signals and cannot be seen 25. Which of the following is true?

　　A.One of the pulsars found by scientists sends radio signals.

　　B.Pulsar began to send radio singals in 1967.

　　C.Scientists have searched for pulsars for many years but found none.

　　D.Scientists have found many pulsars since 1967.

　　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 desertlike.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 aga in 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.

　　26. What is the article mainly concerned?

　　A.The problem of spreading desert.

　　B.The rainfall and vegetation in desert areas.

　　C.The water collection systems.

　　D.The difference between modern life and ancient life.

　　27. “one out of seven” refers to____.

　　A.more than a third of the lands' earth

　　B.the percentage of the earth's land that is desert-like

　　C.the number of people who live in dry regions

　　D.a day of a week

　　28. In paragraph 2,“they are taken to the greener lands in the south.”They

　　refers to____.

　　A.the Sahel farm land B.the farmers

　　C.the cattles D.the trees

　　29. How many ideas for saving the land are described?

　　C.Four. D.Three.

　　30. Which of the following statements is true, according to the passage?

　　A.The earth's desert are slowly spreading.

　　B.One out of 10 people lives in dry regions.

　　C.Their life in the desert is threatened now by traditional problems.

　　D.New water wells can solve the problem in Africa's desert.

　　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

　　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 healthrelated 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 lifestyle”(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

　　C.statistical evidence D.opinions of friends

　　Attend Your Classes Regularly

　　Nowadays it is a very common phenomenon that some university students are late for or even absent from their classes. And still there are some students who slip out of the classroom before the class is over. Class attendance has become a thorny problem to both the students and the teachers.

　　In fact, it is very important for the students to attend their classes regularly. First, it will ensure you to catch up with the teachers in your learning. That is very helpful to you if you want to do a good job in your study. Second, attending classes regularly is a way of showing respect to your teachers, too. Your teachers will feel bad if the students do not attend their classes, which, in return, will affect their teaching and be no good for the students. Third, attending classes regularly will help to form a good habit of punctuality, which is of great importance for the students to do a good job in the future.

　　Therefore, we university students should form the good habit of attending our classes regularly from now on. And some day we will benefit from it.
