问题     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【C1】______,【C2】______the jobs must be carried【C3】______at the same time. Because we depend so【C4】______upon science and technology for our【C5】______, we must produce specialists in many fields.【C6】______we live in a【C7】______nation, whose citizens make the policies for the nation, large numbers of us must be educated to understand, to uphold, and【C8】______necessary, to judge the work of【C9】______The public school must educate both producers and【C10】______of scientific services.
    In education, there should be a good balance【C11】______the branches of【C12】______that contribute to effective thinking and【C13】______judgment. Such balance is defeated by【C14】______much emphasis on any one field. This【C15】______of balance involves not only the【C16】______of the natural sciences, the social sciences and the arts but also relative emphasis among the natural sciences themselves.
    【C17】______, we must have a balance between current and【C18】______knowledge. The attention of the public is continually drawn to new【C19】______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【C20】______for beginners."
【C3】
选项 A、off
B、forward
C、away
D、on
答案D
解析 “carry on”表示“坚持下去；继续下去”，而且“carry on”与原文中的“atthe same time同时”是一种搭配，而且根据原文意思：“由于这种工作必须同时继续下去”，所以应是“carry on”。而“carry off拿走；搬走；抓走；夺走；致……死亡”，“carry forward推进，使前进”，“carry away拿走，搬走；抢走；冲走，卷走；使激动而失去自制力；吸引住”均不符合题意。
