单选题Most people agree that fencing (击剑) is one sport in which a person must be at least 30 years old before he learns all he needs to know about the sport. But Clark Summers of the University of Detroit has shown that this doesn"t always have to be true. Clark is a different kind of fencer in a lot of ways. He is American, while most fencers are from the countries of Europe. He is black while most fencers in the past have been white. And he is only 22 years old. Many people think that Clark is the most promising fencer in this country today. Although he is young, he has been able to master the necessary skills. Already he has won a number of fencing contests (竞赛) against older fencers. He is almost certain to become a member of the U. S. Olympic (奥林匹克) fencing team! "There is no real danger in fencing, today," Clark says. "But I never forget that fencing was not always a sport. In the old days, People fenced to settle a quarrel. Each match was a matter of life and death. If that came true in the matches I play in today, every touch against me would mean that I had been wounded or killed. So I try to play as if l were fencing for my life. I don"t like the idea of being killed!"

单选题{{B}}D{{/B}} 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 two jobs must be carried on at the same time. Because we depend so heavily upon science and technology for our progress, we must 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 judgement. Such balance is defeated by too much emphasis on any one field. This question of balance involves not only the relation of the natural sciences, the social sciences, and the arts but also relative emphasis among the natural sciences themselves. Similarly, we must have a balance between the 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.
