The order came that soldiers ______the village the next morning A should leave B had to leave

题目

The order came that soldiers ______the village the next morning A should leave B had to leave
The question came up at the meeting _____we had enough money for our research.
A wether Bif
分别选哪个答案 ,为什么?
第一题我觉得既然是ORDER 命令 那肯定应该选
第二题 WEther 和 if 的区别用法在哪里

答案

第一题只能选A,因为主句里主语、谓语或宾语只要出现类似order这样的词,其从句就必须使用should do,而should 时常可省略,所以经常会看到出现考试题里的答案是do.
第二题选A,因为这里的从句是主语The question的同位语,符合下面这个语法定义：
引导主语从句时,只能用whether,不能用if.
例如：
①It is unknown whether he will come. 他是否来还不知道.
②Whether the news is true remains a question. 这个消息是否真实仍然是个问题.
