He________sleep,although he tried to,when he got on such a hunt for an idea until he had caught it.                                                     (2013·湖南,32)
A.wouldn’t B.shouldn’t
C.couldn’tD.mustn’t

答案

解析
C
解析 考查情态动词的辨析。wouldn’t不会;shouldn’t不应该;couldn’t不能;mustn’t禁止。根据语境可知,他显然是“不能”入睡,根据句中的although he tried to可知这里说的是过去的事情,所以用cannot的过去式。
