— Has Tim started? He said he would join in the party.
— He ____.He is a man of keeping his word.
A.could have left | B.must have left |
C.can’t come | D.won’t be coming |
B
解析試題分析:考查情態(tài)動詞+完成式的用法:句意:Tim是個言出必行的人,所以他肯定會來參加聚會的,這里強調(diào)他一定離家往聚會地點來了,所以用must have left 語氣非?隙ǎ琧ould have done過去可能做了,卻沒做。選B。
考點:考查情態(tài)動詞+have done的用法
點評:情態(tài)動詞+have done可以表示推測和虛擬:“must+have+done”表示對過去事情的肯定推測,譯成“一定做過某事”,該結(jié)構(gòu)只用于肯定句!癱an't+have+done”表示對過去事情的否定推測,譯成“不可能做過某事”。 “may+have+done”表示對發(fā)生過的事情的推測,意思是“可能已經(jīng)”或“也許已經(jīng)”,用于肯定句中。 “could+have+done”是虛擬語氣,表示對過去事情的假設(shè),意思是本來能夠做某事而沒有做。 “would+have+done”虛擬語氣,表示對過去事情的假設(shè),意思是“本來會做”。
