问题 We cannot always______the wind, so new windmills should be so designed that they can also be driven by water.
选项 A、hang on
B、count on
C、hold on
D、come on
答案 B
解析 这是一组带on的短语动词。come on“偶然遇到"(on是介词，也可用upon)，属于干扰项，可排除；hang on和hold on有下列相同的意思(on是副词，不能用upon代替)：(1)“紧紧抓住不放”。如：The climber had to hang on(hold on)while his com—panions went to find a rope． “攀登者不得不紧紧抓住，与此同时，他的伙伴去找绳子。”(2)(多用于接电话时)“等一下”。I’m afraid the line is busy，would you like tohang on(hold on)?“占线，请你等一下。”(3)(尽管有困难)“坚持下去”。Paintingthe house is tiring，but if you hang on(hold on)，the results are worth the effort．“粉刷房屋是累人的活，但如果坚持下去，从结果看还是值得干的。”count on和hang on都有depend on的意思(这里的on是介词，可以用upon代替)，但是count on作“指望，依赖”讲，一般由某人作主语，宾语可以是someone或something；hang on意思是“靠……决定……，取决于……”，多用物作主语，宾语只能用something。试比较下列句子：Don’t count on your relatives to help you out of trouble．“不要指望你的亲戚帮你摆脱困难。”I’d like to come with you but that’s not a promise，don’t count on it．“我愿意和你去，但这不是许诺，别抱希望。”这两句都不能用hang on。The casehangs upon the judge’s opinion of the prisoner’s character．“案子的处理取决于法官对罪犯品质的意见。”His whole career hangs on whether he can pass the exam．“他今后的发展取决于是否能通过考试。”这两句也不能换成count on。综上所述，按句意只能选择B。
