[英语辅导]小升初英语语法零基础:may have done用法小结
发布时间:2016-11-16 11:11:38 点击:
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 don't 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/mightn't have done 表“可能不” 之前我们讲到过 can't/couldn't have done 是表示“不可能”,而 may not/mightn't have done 则是表示“可能不”,要注意区分哦: He can't have been at the meeting, he's on a business trip this week. 他不可能有出席会议,他这周出公差。 We couldn't 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 mightn't have regarded me as their friend. 他们可能没有把我当作朋友看待。 |
