历年英语四级考试的阅读理解部分3

　　Passage One

　　Questions 21 to 25 are based on the following passage.

　　With fifteen years Britain and other nations should be well on with the building of huge industrial complexes for the recycling of waste. The word rubbish could lose its meaning because everything which goes into the dumps would be made into something useful. Even the most dangerous and unpleasant wastes would provide energy if nothing else.

　　The latest project is to take a city of around half a million inhabitants and discover exactly what raw materials go into it and what go out. The aim is to find out how much of these raw materials could be provided if a plant for recycling waste were built just outside the city. This plant would recycle not only metal such as steel, lead and copper, but also paper and rubber as well.

　　Another new project is being set up to discover the best ways of sorting and separating the rubbish. When this project is complete, the rubbish will be processed like this: First, it will pass through sharp metal bas which will tear open the plastic bags in which rubbish is usually packed; then it will pass through a powerful fan to separate the lightest elements from the heavy solids; after that grounders and rollers will break up everything that can be broken. Finally, the rubbish will pass under magnets , which will remove the bits of iron and steel; the rubber and plastic will then be sorted out in the final stage.

　　The first full-scale giant recycling plants are perhaps fifteen years away. Indeed, with the growing cost of transporting rubbish to more distant dumps, some big cities will be forced to build their own recycling plants before long.

　　Passage Two

　　Questions 26 to 30 are based on the following passage:

　　By 1970, according to a World Wildlife Fund report, only about 4,500 tigers survived throughout the world-half of them in India. Mr. Foresters, who followed and counted tiger footprints, estimated that in May 1972 only about 1,800 tigers existed in India. Project Tiger Supported by W.W.F. was immediately launched. Nine tiger reserves were created, with armed guards protecting them.

　　The project provided opportunities for researchers from India and abroad to study tigers in the reserves and gather previously unavailable information about their habits. Studies show that a male tiger may control a hunting territory of between 10 and 20 sq. kms. depending on its age, size and strength. The territory of male includes the smaller territories of three or four tigressess. A tiger marks the boundaries of its territories by spraying urine and other bodily liquids on bushes. But it tries to avoid territorial fights, being guided by the distinctive body smell of other tigers. Tigers fight to death only when a tigress is defending her young, or when a tiger is guarding a tigress from the attentions of other males.

　　The popular image of the tiger is that of a merciless and unconquerable hunter. But studies show that it catches only one of 20 victims it tries to attack.

　　Fears have recently developed that Project Tiger has been too successful. It has enabled the tiger population to double , but Indias human population has also grown out of control. Currently it is 750 million and likely to be 900 million by the end of the century. Land problem is becoming serious and many rural people feel bitter about the fact that some rich forests are reserved for tigers. A growing number of attacks by tigers on man has added to the hostility .

　　Passage Three

　　Questions 31 to 35 are based on the following passage.

　　In only two decades Asian Americans have become the fastest-growing U.S. minority . As their children began moving up through the nations schools, it became clear that a new class of academic achievers was emerging. Their achievements are reflected in the nations best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics and science is partly explained by the fact that Asian-American students who began their educations abroad arrived in the U.S. with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel there will be less unfair treatment in areas like mathematics and science because they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.

　　Most Asian-American students owe their success to the influence of parents who are determined that their children take full advantage of what the American educational system has to offer. An effective measure of parental attention is homework. Asian parents spend more time with their children than American parents do, and it helps. Many researchers also believe there is something in Asian Culture that breeds success, such ideals that stress family values and emphasize education.

　　Both explanations for academic success worry Asian Americans because of fears that they feed a typical racial image. Many can remember when Chinese, Japanese and Filipino immigrants were the victims of social isolation. Indeed, it was not until 1952 that laws were laid down giving all Asian immigrants the right to citizenship.

　　31. While making tremendous achievements at college, Asian-American students ______.

　　feel they are mistreated because of limited knowledge of English

　　generally feel it a shame to have to depend on their parents

　　32. What are the major factors that determine the success of Asian Americans?

　　A solid foundation in basic mathematics and Asian Americans?

　　Hard work and intelligence.

　　Parental help and a limited knowledge of English.

　　Asian culture and the American educational system.

　　33. Few Asian-American students major in human sciences mainly because ______.

　　their English is not good enough

　　they are afraid they might meet with unfair judgement in these areas

　　there is a wide difference between Asian and Western cultures

　　they know little about American cultures and Western cultures

　　34. Why do the two explanations worry Asian Americans?

　　They are afraid that they would again be isolated from American society in general.

　　People would think that Asian students rely on their parents for success.

　　Asian American would be a threat to other minorities.

　　American academic achievements have taken on too strong an Asian character.

　　35. The authors tone in this passage is _____.

　　sympathetic doubtful critical objective

　　Passage Four

　　Questions 36 to 40 are based on the following passage.

　　Like fine food, good writing is something we approach with pleasure and enjoy from the first taste to the last. And good writers, good cooks, do not suddenly appear full-blown. Quite the contrary, just as the cook has to undergo an intensive training, mastering the skills of his trade, the writer must sit at his desk and devote long hours to achieving a style in his writing, whatever its purpose-schoolwork, matters of business, or purely social communication. You may be sure that the more painstaking the effort, the more effective the writing, and the more rewarding.

　　There are still some remote places in the world where you might find a public scribe to do your business or social writing for you, for a fee. There are a few managers who are lucky enough to have the service of that rate kind of secretary who can take care of all sorts of letter writing with no more than a quick note to work from. But for most of us, if there is any writing to be done, we have to do it ourselves.

　　We have to write school papers, business papers or home papers. We are constantly called on to put words to paper. It would be difficult to count the number of such words, messages, letters, and reports put into the mails or delivered by hand, but the daily figure must be enormous. What is more, everyone who writes expects, or at least hopes. We want whatever we write to be read, from first word to last, not just thrown into some letters-to-be-read file or into a wastepaper basket. This is the reason we bend our efforts toward learning and practicing the skill of interesting, effective writing.
