試題分析:考查情態(tài)動(dòng)詞用法。本題考查的是情態(tài)動(dòng)詞對過去情況的推測,使用“情態(tài)動(dòng)詞+have done”的形式。Can have done通常用語疑問句否定句中。Must have done一定做了某事;表示對過去所發(fā)生事情有抱把握的肯定推測。句意:—你可能會(huì)被選為我們足球隊(duì)的隊(duì)長嗎?—是的,他肯定已經(jīng)被選上了。難道你沒有看見他帶著隊(duì)長的袖標(biāo)嗎?故C正確。
點(diǎn)評:情態(tài)動(dòng)詞的用法比較復(fù)雜。突出的是表示推測:如果是對現(xiàn)在的情況進(jìn)行推測,使用“情態(tài)動(dòng)詞+動(dòng)詞原形”;對過去的情況進(jìn)行推測,使用“情態(tài)動(dòng)詞+have done”;情態(tài)動(dòng)詞也經(jīng)常用于虛擬語氣,要分具體情況來分析,在條件句中和賓語從句,表語從句中都有體現(xiàn)。
