典型例题

　　例1 It is hard ____ him ______ change his mind.
　　A. of you to make; to　　B. for you to make; 不填
　　C. for you to make; to　　D. of you making; 不填
　　分析：动词不定式作主语时，如果主语太长常以it作形式主语，而把真正的主语置于句尾，以避免“头重脚轻”。即构成It is + adj. + to do sth. 结构；同时如果不定式短语前有逻辑主语，则应考虑用for 或of。一般来说，句中形容词是表示“人的特性”时用of, 否则用for.第二空为make的宾语补足语不能带to. 故本题答案为B。

　　例2 You will find this map of great ____ in helping you to get round London.
　　A. price　　B. cost　　C. value　　D. usefulness
　　分析：price为“价格”；cost为“费用”；value为“价值”；usefulness为“有用”；而本句话的意思是“这张地图在帮助你浏览伦敦方面很有价值”，因此选择答案为C。

　　例3 —Will somebody go and get Dr. White?
　　　　—He’s already been ______.
　　A. asked for　　B. sent for　　C. called for　　D. looked for
　　分析：ask for (请求得到，要求给予)，send for （派人去请），call for(要求，需要，邀约)及look for (寻找)的意义。根据题意，正确答案为B。

　　例4 Is ______ possible to fly to the moon in a spaceship?
　　A. now　　B. man　　C. that　　D. it
　　分析：“It is + adj. + (for sb. ) to do”为固定句型，其中it为形式主语。形式主语只能由it来充当，因此正确答案为D。
　　例5　She ______ his number in the phone book to make sure she had got it right.
　　A. looked up　　B. looked for　　C. picked out　　D. picked up
　　分析：look up(查阅), look for, pick out(挑选)及pick up时性（捡起，接收，接送）的意义。根据题意，正确答案为A。

　　例6 What he said at the meeting is of ______.
　　A. very important　　B. great important
　　C. very importance　　D. no importance
　　分析：“(be) of + 抽象名词”为固定结构。介词of后应为名词。选项C中的副词very不能修饰名词importance，正确答案为D。
