题目

关于倒装句,请帮我看看下面两道题,
__time,they woule certainly come
1 if they had 2 if had they 3 had they 4 both 1 and 2
我能理解为什么选if they had 但是不理解为什么if had they也是对的?它符合倒装句的什么条件啊?
____,we would not leave
1 should not ist rain tomorrow
2 if should not rain tomoorow
3 is it did not rain tomorrow
4 if it does not rain tomorrow
这道题为什么4是对的?其他选项为什么是错的错在哪里?

答案

解析：第一题的参考答案有误,4应该是both1 and 3,那就对了.这句话有两种表达方式：
1.If they had time,they would certainly come.2.Had they time,they would certainly come.
都是表达虚拟语气,第二种是带倒装的虚拟语气.
第二题的答案是4,没错,表达虚拟语气,if it doesn't rain tomorrow,we would not leave.
其他选项的句子结构都不对,第1个选项哪怕要对,也应该是should it not rain tomorrow,2、3的语序明显错误.
