Question

—No wonder you caught a cold. You ________out last night without a coat.
—I know how silly I was.

A．shouldn’t have gone	B．mustn’t have gone
C．couldn’t have gone	D．mightn’t have gone

Answer 1

A

本題考查“情態(tài)動(dòng)詞＋have done ”結(jié)構(gòu)的用。mustn’t have gone 是錯(cuò)誤的表達(dá)，couldn’t have gone 和mightn’t have gone 雖然也有“本不應(yīng)該做卻做了”含義，但其語氣遠(yuǎn)shouldn’t have gone 弱，且它們主要用來表示對(duì)過去是否發(fā)生某一行為進(jìn)行推測(cè)。
