这个介词要接不定式

请看下面一道题：

Every minute should be made full use of _________ the lessons.

A. to study              B. study                   C. studying                  D. studied

【分析】此题容易误选C，认为介词后接动词时要用动名词。其实此题的正确答案是A，注意此句谓语为被动语态，假若将此句转换成主动语态，则是 We should make full use of every minute to study the lessons. 用的是 make use of … to do sth (利用……做某事)这一结构。另外，还有 make the most of (尽量利用)，make the best of (尽量利用)也可能用于此类试题。请看类例：(from www.nmet168.com)

The only way that she thought of _________ enough money was to sell her hair.

A. get                     B. to get                    C. got                        D. getting

答案应选B，而不是选D。句子主语是 the only way，that she thought of 是修饰主语的定语从句，不定式 to get enough money 也是修饰主语的定语，也就是说，句子主语带有两个定语修饰语。全句意为“她想到的弄到足够钱的惟一办法就是把自己的头发卖掉。”
