2.情态动词may/might+完成时结构，表示对过去某事可能性的推测，意为可能已经……。用might比用may只是在语气上更增加了不确定的成份,更表示怀疑和不肯定。如：

You may have got a fever.

You might have got a fever.

▲might +动词完成时有时表示“本来可能”，“就仿佛”，“简直可以”，或者用来提出请求、建议以及婉转的批评等。如：

How quickly time passed! It might have happened yesterday!

You might have made even greater progress.

▲may/might + 动词一般时的区别也是同样道理，即might比may的语气更加不肯定，表示的都是现在时。如：

I'm only afraid I may be bored.
