Question

She __________ have left school, for her bike is still here.

A. can’t                                 B. wouldn’t                           C. shouldn’t                                  D. needn’t

Answer

A

【解析】

试题分析:考查情态动词用法。根据后句her bike is still here可知此处是有把握的判断，can’t have done “不可能做过某事”；B wouldn’t have done“不会做某事（虚拟语气）”；C shouldn’t have done “本不应该做某事”；D needn’t have done “本来没必要做某事”。由此判断A选项正确。句意：她不可能离开学校了，因为她的自行车还在这里。
