She might have got up now.

　　現(xiàn)在她可能已經(jīng)起床了。

　　may/might have done 預(yù)測未來

　　may/might+動詞的完成式表示推測將來某時之前的情況。例如：

　　He may have left when you get there.

　　等你到達的時候他可能已經(jīng)離開了。

　　注意：may have done 和 might have done 表推測時，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.

　　時間過得好快啊！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 表輕微責備

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

　　The proposal might have been refused.

　　這個建議本該拒絕的。(有輕微的責備之意)
