7. stop等动词后接不定式或动名词含义不同

He was very tired so he stopped ______ a rest.

A. have                    B. to have                C. having                 D. to having

此题应选B。在动词stop(停止), go on(继续)等之后, 接不定式或动词的-ing形式都可以，但含义有差别：stop之后若接不定式, 表示停止正在做的事情而去做另外一件事(即去做不定式表示的动作);若接动词的-ing形式, 则只表示停止正在做的事情(即停止-ing动词所表示的动作)；go on 之后若接不定式，表示的是做完一件事情后, 接着做另外一件事(即做不定式所表示的动作)；若接动词的-ing形式, 则表示继续做正在做的事(即继续做-ing动词表示的动作)。如：

1. He reached the top of the hill and stopped ___ on a big rock by the side of the path.
