从零开始学语法:may have done用法小结

发布时间:2016-03-02  编辑:查字典英语网小编

  may/might have done 推测过去

  may/might+动词的完成式表示对过去发生的行为的推测。例如:

  -Whatever has happened to George?

  -乔治发生了什么事?

  -I dont know. He may have got lost.

  -我不知道,他可能迷路了。

  You might have read about it in the papers.

  你可能在报上已经看过这个消息了。

  (之前我们做过can have done用法小结,can have done表推测时都是对过去进行推测,但是may have done不仅可以推测过去)

  may/might have done 推测现在

  may/might+动词的完成式表示对现在情况的推测。例如:

  She might have got up now.

  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)

  I might have taken another path.

  我本可以走另一条路。

  may not/mightnt have done 表可能不

  之前我们讲到过 cant/couldnt have done 是表示不可能,而 may not/mightnt have done 则是表示可能不,要注意区分哦:

  He cant have been at the meeting, hes on a business trip this week.

  他不可能有出席会议,他这周出公差。

  We couldnt have done it without you.

  没有你我们肯定完成不了。

  They may not have known it beforehand.

  他们事先可能不知道这事儿。

  They mightnt have regarded me as their friend.

  他们可能没有把我当作朋友看待。
