Question

You have a big mouth, Li Fei. You ________ have told everybody the secret.

A．can't

B．mustn't

C．shouldn't

D．mightn't

Answer 1

C

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。句意：你真是大嘴巴，你本不應(yīng)該被這個(gè)秘密告訴每個(gè)人的。故C正確。
點(diǎn)評(píng)：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。
