A.Keep B.Keeping C.To keep D.Having kept
,为什么?

——What should I do, doctor ? ——____ healthy ,you should take more exercise.
A. Keep B. Keeping C. To keep D. Having kept 答案是C
解析:动词不定式作主语,表目的
中文:医生,我该怎么做?为了保持健康,你要多运动。

C
to表示目的,后面说你应该更多地锻炼,所以前文应该说为了保持健康

to keep healthy(to do)动词不定式作目的状语,表示为了.,这里指为了保持健康,你应该做更多的锻炼.

此处的to do 表示目的,为了保持健康,你应该多锻炼身体。
