Question

My sister met him at the street yesterday afternoon, so he __________ your lecture.

A．shouldn’t have attended	B．needn’t have attended
C．mustn’t have attended	D．couldn’t have attended

Answer 1

D

試題分析：考查情態(tài)動(dòng)詞用法。Shouldn’t have done本不應(yīng)該做某事，實(shí)際上卻做了（虛擬語(yǔ)氣）；couldn’t have done不可能做某事（對(duì)過去情況的推測(cè)）；needn’t have done本不需要做某事，實(shí)際上卻做了（虛擬語(yǔ)氣）；句意：我的姐姐昨天下午在街上遇見了他，所以他不可能去聽了你的演講。故B正確。
點(diǎn)評(píng)：考本題是高考必考考點(diǎn)，一定要牢記句型意思。must have done過去肯定做了某事。should have done 本應(yīng)該做而實(shí)際未做。can’t have done 過去不可能做了某事；shouldn’t have done 本不應(yīng)該做而實(shí)際做了。 need have done 本有必要做某事；needn’t have done 本沒有必要做某事；注意沒有 mustn’t have done的形式。
