A. shouldn’t

B. mustn’t

C. can’t

D. wouldn’t

答案:

A. shouldn’t

B. mustn’t

(答案→)C. can’t

D. wouldn’t

解析:考查情态动词+完成式的用法:句意:--你知道玛丽在哪里吗?--她不会走远的,她的外套还在这里。从her coat’s still here.可知是否定推测,can’t have done“过去不可能做了”,肯定推测用must have done“过去一定做了”,shouldn’t have done过去本不应该做而做了, wouldn’t have done过去本不会做而做了,选C。
