1) may have + done sth, can have + done sth表示過去，推斷過去時間里可能發(fā)生的事情。

Philip may have been hurt seriously in the car accident.

Philip can have been hurt seriously in the car accident.

2)must have +done sth，對過去時間里可能發(fā)生的事情的推斷，語氣較強(qiáng)，具備"一定"，"諒必"的意思。

3) ought to have done sth, should have done sth

本應(yīng)該做某事，而事實(shí)上并沒做。否定句表示"不該做某事而做了"。
