—I can’t find my mobile phone anywhere.
—You _____ have lost it while eating out.
A.mayB.needC.wouldD.should
A

试题分析:考查情态动词用法。May have done也许做某事(对过去发生的情况进行推测);need have done 本需要做某事,实际上却没有做;would have done本会做某事,实际上却未做;should have done本应该做某事,实际上却没有做;句意:—我不到我的手机了。—你也许在吃饭的时候把手机给丢了吧。根据句意说明A正确。
点评:情态动词+have done有多种用法。可以表示推测,也可以表示虚拟语气。May have done也许做某事(对过去发生的情况进行推测);need have done 本需要做某事,实际上却没有做;would have done本会做某事,实际上却未做;should have done本应该做某事,实际上却没有做;
