问题补充：

—I can’t find my mobile phone anywhere.

—You have lost it while eating out.

A. may

B. need

C. would

D. should

答案：

(答案→)A. may

B. need

C. would

D. should

解析：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。
