“can / could have done”表示“對(duì)過(guò)去某種情況的懷疑或不確定”。can和could一般用于否定句和疑問(wèn)句,could的語(yǔ)氣較can弱。例如:
I didn’t see her at the meeting this morning, she can’t / couldn’t have spoken at the meeting.
早上會(huì)議上我沒(méi)看見(jiàn)她,她不可能在會(huì)議上發(fā)言。
He can’t have finished the work so soon.
他不可能這么快就完成工作。

It must have rained last night, for the ground is wet.
一定下過(guò)雨了,地面很濕。
(2)should have done常談?wù)撨^(guò)去的情況,主要用于指“本該發(fā)生而實(shí)際上未發(fā)生的事”。例如:
You should have told me so before.

Look at the time! We should have been at the theatre ten minutes ago.
瞧,都什么時(shí)候了!十分鐘前我們就該到戲院了。
(3)may / might have done表示“對(duì)已發(fā)生的動(dòng)作或存在的狀態(tài)進(jìn)行不是很肯定的推測(cè)”,might的語(yǔ)氣比may弱一點(diǎn)。這種結(jié)構(gòu)主要用于肯定句和否定句。例如:
He may have already done his work. 他也許已經(jīng)做完了工作。
