He might have given you more help,even though he was busy.他或许会多给你一些帮助,即使他很忙.
1.这里的might have done做什么用法
2.mightn't have done意思
3.may have done 和may have done意思用法一样吗

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
