Questions 1 to 10 are based on the same passage or dialog.

In the Pittsburgh suburb of Wilkinsburg, March 1, a gunman shot down five men —killing three and injuring two —in an apparently racially motivated rage.

But this time, there were two

features in

the racial attacks:

First, the suspect was a black. Second, no black leader or organization immediately rushed forth to

condemn the shootings. And there was no demand that the suspected shooter, Ronald Taylor, be

punished by law if he shot the men because they were white.

Some blacks I know privately

off the

killings with the bitter remark that whites have been killing blacks for years and getting away with it and that the law did not do anything about the killings.

The victims of Taylor's

were innocents

who happened to be in the wrong place at the wrong time —apparently shot because they were white. While the shooting appears to be an extreme example of

violence, it is not unusual. More whites

than ever are the

of attacks by blacks.

Part 4 Reading Comprehension (Multiple Choice)

(每小题：2 分)

Directions: Read the following passages carefully and choose the best answer from the four choices marked A, B, C and D.

Questions 1 to 5 are based on the same passage or dialog. One phase of the business cycle is the expansion phase. This phase is a two-fold one, including recovery and prosperity. During the recovery period there is ever-growing expansion of existing facilities, and new facilities for production are created. More businesses are created and older ones expanded. Improvements of various kinds are made. There is an ever increasing optimism about the future of economic growth. Much capital is invested in machinery or heavy industry. More labor is employed. More raw materials are required. As one part of the economy develops, other parts are affected. For example, a large expansion in automobiles results in an expansion of the steel, glass, and rubber industries. Roads are required; thus the cement and machinery industries are stimulated. Demand for labor and materials results in greater

prosperity for workers and farmers from increased demand for supplies of raw materials. This increases purchasing power and the volume of goods bought and sold. Thus prosperity is diffused (扩散) among the various segments of the population. This prosperity period may continue to rise and rise without an apparent end. However, a time comes when this phase reaches a peak and stops spiraling (盘旋上升) upwards. This is the end of the expansion phase.

1.We may assume that in the next paragraph the writer will

discuss ________.

A. the expansion phase

B. the status of the farmer

C. the higher cost of living

D. the recession period

2.The title below that best expresses the ideas of this passage

is ________.

A. Attaining Prosperity in One Industry

B. The Recovery Stage

C. An Expanding Society

D. A Period of Growth

3.Prosperity in one industry ________.

A. reflects itself in many other industries

B. will affect the steel industry

C. will spiral upwards

D. will end abruptly

4.Which of the following industries will probably be a good

indicator of a period of expansion?

A. Toys.

B. Machine tools.

C. Foodstuffs.

D. Materials.

5.During the period of prosperity, people regard the future

________.

A. cautiously

B. in a confident manner

C. in a careful way

D. indifferently

Questions 6 to 10 are based on the same passage or dialog.

Are organically grown foods the best food choices? The advantages claimed for such foods over conventionally grown and marketed food products are now being debated. Advocates of organic foods—a term whose meaning varies greatly—frequently proclaim that such products are safer and more nutritious than others.

The growing interest of consumers in the safety and nutritional quality of the typical North American diet is a welcome development. However, much of this interest has been sparked by sweeping claims that the food supply is unsafe or inadequate in meeting nutritional needs. Although most of these claims are not supported by scientific evidence, the great number of written material advancing such claims makes it difficult for the general public to separate fact from fiction. As a result, claims that eating a diet consisting entirely of organically-grown foods prevents or cures disease or provides other benefits to health have become widely publicized and popular among customers.

Almost daily the public is surrounded by claims for "no-aging" diets, new vitamins, and other wonder foods. There are numerous unsubstantiated (无确实根据的) reports that natural vitamins are superior to synthetic ones, that fertilized eggs are nutritionally superior to unfertilized eggs, that untreated grains are better than fertilized grains, and the like.

One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods. But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods. So there is real cause for concern if consumers, particularly those with limited incomes, distrust the regular food supply and buy only expensive organic foods instead.

6.The word "Advocates" (Para. 1) is closest in meaning to which

of the following?

A. Supporters.

B. Merchants.

C. Inspectors.

D. Consumers.

7.What does the word "others" (Para. 1) refer to?

A. Advantages.

B. Advocates.

C. Organic foods.

D. Nonorganically-grown products.

8.The author implies that there is cause for concern if

consumers with limited incomes buy organic foods instead of conventionally grown foods because ________.

A. organic foods can be more expensive but are often no better than conventionally-grown foods

B. many organic foods are actually less nutritious than similar

conventionally-grown foods

C. conventionally-grown foods are more readily available than

organic foods

D. too many farmers will stop using conventional methods to

grow food crops

9.According to the last paragraph, consumers who believe that

organic foods are better than conventionally-grown foods are often ________.

A. careless

B. mistaken

C. mistaking

D. wealthy

10.What is the author's attitude toward the claims made by

advocates of health foods?

A. Very enthusiastic.

B. Somewhat favorable.

C. Neutral.

D. Doubtful.

Questions 11 to 15 are based on the same passage or dialog. For me, scientific knowledge is divided into mathematical sciences, natural sciences or sciences dealing with the natural world, and sciences dealing with mankind. Apart from these sciences is philosophy. In the first place, pure or theoretical knowledge has been sought only for the purpose of understanding. What distinguishes man from animals is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance, because they also contribute to defining

him as man and permit him to pursue a life increasingly more truly human.

But even while enjoying the results of technical progress, he must defend the value of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but pure or theoretical knowledge will not. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic (圆锥形的) sections, keenly and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first men to study the nature of electricity could not imagine that their experiments, carried on because of mere intellectual curiosity, would eventually lead to modern electrical technology, without which we can scarcely think of contemporary life. Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. But, in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.

11.The most important advances made by mankind come from

________ according to the passage.

A. practical applications of social sciences

B. practical applications of pure knowledge

C. sciences dealing with the natural world

D. the biological sciences

12.The author does NOT include among the sciences the study

of _________.

A. chemistry

B. astronomy

C. economics

D. literature

13. The author points out that the Greeks who studied conic

sections ________.

A. were mathematicians

B. were interested in navigation

C. were unaware of the practical value of their studies

D. worked with electricity

14. The title below that best expresses the ideas of this passage

is ________.

A. Technical Progress

B. A Little Learning Is a Dangerous Thing

C. Man's Distinguishing Characteristics

D. The Value of Pure Knowledge

15. Pure knowledge is valuable for its own sake because

________.

A. it is sought only for the purpose of understanding

B. it is the foundation for practical results

C. people are keen on it
