試題分析:考查情態(tài)動(dòng)詞can的用法:can+完成時(shí),表示推測(cè)的時(shí)候,can用于疑問(wèn)和否定句,第一空是用于疑問(wèn)句,用can,第二空是用于否定句,can't。瑁幔觯濉。洌铮睿暹^(guò)去不可能做了什么,句意:瑪麗把空瓶子放在哪里呢?――她不可能扔了的。一定在什么地方。選A。
點(diǎn)評(píng):使用“情態(tài)動(dòng)詞+have done”對(duì)過(guò)去的情況進(jìn)行推測(cè)。如果是對(duì)現(xiàn)在情況的推測(cè)或虛擬,使用“情態(tài)動(dòng)詞+動(dòng)詞原形”;
