-----Do you know where David is ?  I couldn’t find him anywhere.
-----Well. He _______have gone far-----his coat’s still here.
A.shouldn’tB.mustn’tC.can’tD.wouldn’t
C

試題分析:連詞情態(tài)動詞用法。Shouldn’t have done本不應(yīng)該做某事,實際上卻做了(這是一個對過去情況的虛擬);can’t have done不可能做了某事(對過去所發(fā)生的事情的否定推測);句意:—你知道David在哪里?我到處都找不到他、—他不可能走遠(yuǎn),因為他的外套仍然在這里。根據(jù)句意說明C正確。
點(diǎn)評: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。
