Question

You must be very tired. Why  not  ___________a rest?

A. to stop to have            B. to stop having

C. stop to have               D. stop having

Answer

C

【解析】

试题分析：句意：你一定非常累。为什么不停下来去休息一下呢？Why not do sth？“为什么不做某事”，表示建议，故此处用动词原形stop。stop doing sth“停止做某事”， stop to do sth“停下来去做某事”。根据You must be very tired.可知非常累了，应是停下来去休息，故用stop to have a rest。故选C。

考点：考查动词不定式的用法。
