情态动词高中英语As she’s not here,I suppose she _____ home.A.must go\x05B.must have goneC.might go\x05D.might be going为何不选A
must的意思是命令的意思,如,you must come here quickly when you finish your work.
must,不容置疑的,必须的,是非常强烈的命令语气.所以当然不选A了

C

B. must have gone
这里应该是表示猜测的意思，A是指必需回家的意思，不符合题意

猜测“她回家”，动作发生在过去，所以排除AC；D项为进行时，不选，所以选B。

A是肯定语气啊，而语气是我猜想她可能回家了，所以不选A
