题目内容
14.I _______ to him because he phoned me shortly afterwards.( )A. | needn't have written | B. | might not have written | ||
C. | couldn't have written | D. | mustn't have written |
分析 我本不需要写信给他的,因为他一会过后就打电话给我了!
解答 答案:A.needn't have done本不需要做某事而做了;might not have done表示推测,过去可能没有做某事;couldn't have done 表示否定推测,不可能做过某事;mustn't have done本身是错误的.结合句意"我本不需要写信给他的,因为他一会过后就打电话给我了!"可知,这里应该用needn't have written,故选A.
点评 本题考查虚拟语气.本题主要是考查情态动词+have done的用法,所以要记牢情态动词+havedone的意思,再结合句意,得出答案.
