He must have lost hiswatch at the moment,__he?A.didn"t B.mustn"t C.hasn"t D.needn"t
我选的是A 我觉得既然他丢掉了手表就已经过去了。
我选的是A 我觉得既然他丢掉了手表就已经过去了。
本题应该是选A
这道题初中英语经常见到.
首先你要知道: "must have + 过去分词" 表示对过去事情的猜测, 这里译成: 那时他一定是把表丢了. 所以反意问句用didn't.
其次, 选C 的朋友分析的也不错: 在英语中你还可以记住一句话: must 表示猜测时反意must 后面的助动词(因为must 只是语气助词). 比如: He must be jack, isn't he ?
但在这里答案一般还是倾向于选dind't, 因为它是表示过去的事情呀!
祝你学习进步!
