—I expected him to be nervous before his speech, but he was as cool as a cucumber.

—He _______ it carefully.

A.could have prepared                    B.shouldn’t have prepared

C.must have prepared                     D.can’t have prepared

 

【答案】

C

【解析】

試題分析:考查情態動詞+完成式的用法:A.could have done過去可能做了什么B. shouldn’t have done本不該做而做了, C. must have done一定已經做了,D. can’t have done過去不可能做了,句意:--我以為他在演講前緊張,但是他很冷靜。--他一定準備的很充分。選C.

考點:考查情態動詞+完成式的用法

點評:情態動詞+完成式要注意把握時間概念。情態動詞無論是表達“推測和可能性”,還是表達“虛擬”這一概念,只要是對過去已經發生的事情進行描述,一律用“情態動詞+have done”這一結構;對現在或將來的事情進行描述,用“情態動詞+動詞或系動詞原形”。
