Question

You must be very tired. Why don’t you______ a rest?

A．stop having

B．stop to have

C．to stop having

D．to stop to have

Answer 1

B

试题分析：why don’t you 后接动词原形，故将CD排除，然后再看stop to do sth，表示停下原来的事，去做另一件事，而stop doing sth，表示停下正在做的事，通过前文内容You must be very tired，可知是停下去休息，故选动词不定式，故选B
点评：要识记，动词的固定词组搭配。
