B．a(chǎn)sking; shouldn't

C．a(chǎn)sked; can’t

D．a(chǎn)sked; mustn’t

Answer 1

C

解析試題分析：原句意思是當(dāng)被問及他認(rèn)為這部小說寫了些什么，杰克就保持沉默。謂語動詞ask和主語Jack是被動關(guān)系。needn't have done 表示過去做了不必做的事情shouldn’t have done 本不該做某事can’t have done 表示對過去某種情況的懷疑或不確定mustn’t have done禁止做，故選C，最符合題意。
考點：本題重點考查情態(tài)動詞的用法和非謂語動詞。
點評：要掌握情態(tài)動詞的用法，謂語動詞ask和主語Jack是被動關(guān)系。needn't have done 表示過去做了不必做的事情shouldn’t have done 本不該做某事can’t have done 表示對過去某種情況的懷疑或不確定mustn’t have done禁止做。
