　　现在她可能已经起床了。

　　may/might have done 预测未来

　　may/might+动词的完成式表示推测将来某时之前的情况。例如：

　　He may have left when you get there.

　　等你到达的时候他可能已经离开了。

　　注意：may have done 和 might have done 表推测时，might 所表示的可能性比 may 小，语气较委婉：

　　How quickly time passed！ It might have happened yesterday.

　　时间过得好快啊！这事好像就发生在昨天。

　　He might have seen the surprise in my face.

　　他或许已经看到了我惊异的表情。

　　might have done 表轻微责备

　　might have done 除了能够表推测，还能表示过去本来可以做而实际并没有做。这时带有轻微的责备之意。例如：

　　The proposal might have been refused.

　　这个建议本该拒绝的。(有轻微的责备之意)
