Question

英语英语求解！刚学虚拟条件句，有几个疑问求解，求各位老师高手专家指教

1、
虚拟条件句中 I 必须用 were 吗 ， 有用was的情况吗？
那么第三人称单数的he和she也用were吗 ？
与现在事实，与将来事实都如此用吗？

2、
虚拟条件句主句除了用would should might could 还能用别的吗？ 有什么区别么？
表示与将来相反的虚拟条件句中，从句用过去式和were to do 和should do 的有区别吗？
那 be用过去事实相反的从句是用什么形式

Answer 1

你好。
1 英语虚拟语气中没有was这个单词。
It is (about / high ) time he WAS here. ---------这里的was并不是虚拟语气，而是句型要求用“一般过去时”。
2 还有ought to, Yesterday,she ought to have come too, but she didn't because she got hurt playing volleyball.

would / should / might / could 的用法各不一样，要看语境决定，不是三言两语能讲清楚的。见
谅。

IF he should come tomorrow == if he were to come tomorrow 在意思上没有区别，一般可以互换。

be用过去事实相反的从句是：
I would have come IF I hand't been busy
==I couldn't / didn't come BECAUSE I was busy.

Answer 2
