may have +过去分词（表示对过去可能发生过某事的推测 ）；例如：
1、He may have said so．他也许这样说过.
2、They may not have known it before．他们以前可能不知道此事.
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.（实际没被拒绝）
关键：may have +过去分词 可以表示对“过去”的推测
“可能性现在完成式”！或者说“推测性现在完成式”
“可能没有做某事”
may have done 和might have done意思用法基本一样
1过去式，表示可能，原形是：may have done(may后面接原形)
2.可能没有做
3.额。。。不是一样吗？？？
差不多
1. 这里的might have done做什么用法 = 可能曾经做过
2.mightn't have done意思 = 可能没有做过
3.may have done 和may have done意思用法一样
