问题     There is a difference between science and technology. Science is a method of answering【B1】______questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships between【B2】______phenomena in nature and with establishing theories that【B3】______to organize these facts and relationships; technology has to do with tools, techniques, and【B4】______for applying the findings of science. Another【B5】______between science and technology has to do with the progress in each.
    Progress in science【B6】______the human factor. Scientists, who seek to understand the universe and know the truth within the highest degree of【B7】______and certainty, cannot【B8】______their own or other people’s likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or【B9】______people—as did Darwin’s theory of evolution. But even an unpleasant truth is【B10】______than likely to be useful; besides, we have the choice of refusing to believe it! But【B11】______so with technology; we do not have the choice of refusing to hear the sound produced by a supersonic aircraft flying overhead; we cannot refuse to breathe polluted air. 【B12】______science, progress in technology must be measured【B13】______the human factor. The purpose of technology is to serve people—people【B14】______not merely some people; and future generations, not merely those who presently wish to【B15】______advantage for themselves.
    We are all familiar with the【B16】______use of technology. Many people blame technology itself【B17】______widespread pollution, resource depletion(枯竭)and even social decay in general—so much【B18】______the promise of technology is "【B19】______". That promise is a cleaner and healthier world. If wise applications of science and technology do not【B20】______a better world, what else will?
【B16】
选项 A、invalid
B、illiterate
C、indecent
D、improper
答案D
解析 本题考查形容词词义辨析。对技术的使用可以是不恰当的，所以选[D]improper“不适合的，不适当的”。其他选项均不符合文意。[A]invalid“无效的，作废的”；[B]illiterate“文盲的，未受教育的”；[C]indecent“不体面的，不合礼仪的”。
