may have done 的用法

你理解错了.看下面的例句：John may have seen the film.(John也许看过这部电影了),我们可以把它改写成：It is possible that John has seen the film.所以从这两句我们可以看出,may have done并不表示“过去应完成但实际上未完成的动作”,其实,“过去应完成但实际上未完成的动作”应该是should have done这个结构：He should have come yesterday,but he didn't.以下两句句子的意义不一样：
1 He should have done his work already(他应该早就做完了工作,但的确没有做完.)
2 He may have already done his work,(他也许已经做完了工作,但讲话人不太肯定.)
