专四模拟试题附参考答案（1） Part III Decide which of the choices given below would best complete the passage if inserted in the corresponding blanks. Mark the best choice for each blank on your answer sheet. The “standard of living” of any country means the average pe rson's share of the goods and services the country produces. A country's standard of living, ____31_______, depends first and 32 on its capacity to produce wealth. “Wealth” in this sense is not money, for we do not live on money 33 on things that money can buy: “goods” such as food and clothing, and “services” such as transport and “__34 __ ” .

Some regions of the world are well supplied with coal and minerals, and have a fertile soil and a 37 climate; other regions possess none of them. Next to natural resources 38 the ability to turn them to use. China is perhaps as well 39 as the USA in natural resources, but suffered for many years from civil and 40 wars, and 41 this and other reasons was 42 to develop her resources. 43 and stable political conditions, and 44 _____ from foreign invasion, enable a country to develop its natural resources peacefully and steadily, and to produce more wealth than another country equally well 45 by nature but less well ordered. A country's standard of living does not only depend upon the wealth that is produced and consumed 46 it own borders, but also upon what is indirectly produced through international trade. 47 Britain's wealth in foodstuffs and other agricultural products would be much less if she had to depend only on 48 _ grown at home. Trade makes it possible for her surplus manufactured goods to be traded abroad for the agricultural products that would 49 be lacking. A country’s wealth is, therefore, much influenced by its manufacturing capacity, 50 that other countries can be found ready to accept its manufactures.

PART V READING COMPREHENSION [25 MIN] In this section there are four passages followed by questions or unfinished statements, each with four suggested answers marked A, B, C and D. Choose the one that you think is the best answer. TEXT A At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don’t act on your impulse, but let it pass instead. You know that to commit the action is wrong in some way and that other people will not accept your behavior. Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject. One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is topic that Americans talk about constantly. It’s not taboo to talk about fat; it’s taboo to be fat. The “in” look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U.S., thin is “in”, fat is “out”. I t’s not surprising, then, that millions of Americans have become obsessed with staying slim and “in shape”. The pursuit of a youthful physical appearance is not, however, the sole reason for America’s fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people’s bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising. 1.From the passage we can infer taboo is__. A.a strong desire to do something strange or terrible. B.a crime committed on impulse. C.behavior considered unacceptable in society’s eyes. D.an unfavorable impression left on other people. 2.Based on the ideas presented in the passage we can conclude “being fat” __ in American society. A.will always remain a taboo. B.is not considered a taboo by most people. C.has long been a taboo. D.may no longer be a taboo some day. 3.The topic of fat is __ many other taboo subjects.
