单选题If it were only necessary to decide whether to teach elementary science to everyone on a mass basis or to find the gifted few and take them as far as they can go, our task would be fairly simple. The public school system, however, has no such choice, for the jobs must be carried on at the same time. Because we depend heavily upon science and technology for our progress, we produce specialists in many fields. Because we live in a democratic nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to support, and when necessary, to judge the work of experts. The public school must educate both producers and users of scientific services. In education, there should be a good balance among the branches of knowledge that contribute to effective thinking and wise judgment. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of natural sciences, the social sciences, and the arts but also relative emphasis among the natural sciences themselves. Similarly, we must have a balance between current and classical knowledge. The attention of the public is continually drawn to new possibilities in scientific fields and the discovery of new knowledge; these should not be allowed to turn our attention away from the sound, established materials that form the basis of courses for beginners.

单选题Nike is one of the world's best-known sports shoe and clothes companies. It earns over $1 billion a year. It markets running shoes, walking shoes, basketball shoes, jogging(慢跑)suits, and many other related products. In spite of its success, Nike relies very much on famous people's support to promote consumer sales. Over the past few years, Nike has made good use of one of the most popular names in sports history: Michael Jordan for Air Jordan basketball shoes and clothing. In the first two years on the market, Nike sold 2 million pairs of Air Jordan's; and sales from the shoes and clothing reached $100 million. Michael Jordan's fee? $2.5 million over five years, a royalty(使用费)on all items sold, and a number of other benefits. Nike's promotion efforts for Air Jordan have been impressive. It decided to hire Michael Jordan after he starred for the gold-medal winning in 1984 U. S. Olympic basketball team. He has since become an exciting popular player in the National Basketball Association. The name Air Jordan came from the shoe's air-sole(充气鞋底) and Michael Jordan's name. The original shoe was a high-top black and red model, designed to be both comfortable and fashionable. Magazine and television commercials, for which Nike has invested $5 million, have shown Jordan leaping and blocking shots. Enormous billboards(户外广告牌)of him in action also have appeared in major cities. McDonald's and coke(可乐)commercials displaying Jordan have enhanced his public image. Nike received early publicity when the Chicago Bulls (his basketball team)refused to let Jordan wear the red and black shoes, since they did not match the team's colors. After getting headlines everywhere, Nike supplied Jordan with shoes in the Bulls' colors.

Despite unfounded reports in the mass media of extremely high injury rates among adult exercisers, there have been few good studies of exercise injuries in populations. One of the difficulties in performing such studies has been the need to identify both the number of cases and the number of people at risk for injury. In other words, it is difficult to know the number of individuals injured and the total number of individuals exercising in the population. But these two figures are necessary in order to calculate (统计) tree injury rates. Normally, injury is defined as an accident that causes a person to stop exercising for at least one week. The best available studies on injury rates show that about 25 to 30 percent of adult runners become "injured" (based on the above definition) over the course of a year. More serious injuries include those for which the injured person seeks medical care. If only they are considered, injury rates are much lower, perhaps in the range of I percent per year. Little is known about the causes of exercise injuries. One factor that has been linked to injury is the amount of exercise; for example, individuals who run more miles are likelier to be injured than those who run fewer miles. Factors such as age, sex, body type, and experience have not been shown to be associated with risk of injury. It seems logical that structural abnormalities, sudden increases in training intensity, and types of equipment used are likely to be related to injury risk. However, data to support these opinions are not available.
