问题描述:

高一英语问问 if Alice ( )this afternoon ,the meeting should be put off
A would not come
B might not come
C should not come
D couldn't have spoken
为啥选C求解

这里用到了if的虚拟语气,表示与将来事实相反,句子结构如下
从句是:
1、If+主语+动词过去式
2、If+主语+were to+ 动词原形
【3、If+主语+should +动词原形】
主句是:【主语+should(或would,might,could)+动词原形】
这里用到了括号中的词,所以选C
