　　He may have left when you get there.

　　等你到達(dá)的時(shí)候他可能已經(jīng)離開了。

　　注意：may have done 和 might have done 表推測時(shí)，might 所表示的可能性比 may 小，語氣較委婉：

　　How quickly time passed！ It might have happened yesterday.

　　時(shí)間過得好快��！這事好像就發(fā)生在昨天。

　　He might have seen the surprise in my face.

　　他或許已經(jīng)看到了我驚異的表情。

　　might have done 表輕微責(zé)備

　　might have done 除了能夠表推測，還能表示過去本來可以做而實(shí)際并沒有做。這時(shí)帶有輕微的責(zé)備之意。例如：

　　The proposal might have been refused.

　　這個(gè)建議本該拒絕的。(有輕微的責(zé)備之意)
