题目

题型：不详难度：来源：

He _____ have completed his work; otherwise, he wouldn’t be enjoying himself by the seaside.

A．should

B．must

C．wouldn’t

D．can’t

答案

解析

此处考查情态动词表示推测的用法。should have done表示过去应该做而实际并没有做，因此淘汰A项。would不用来表推测，因此淘汰C项。B基与D项虽然都可以表示推测，但B项表肯定意义而D项表示否定推测，意为“不可能”，根据句意：他肯定已完成了他的工作；不然，他就不会在海边玩得那么愉快了。可知此处需要肯定意义，因此淘汰D项。
