谁知道虚拟语气这个语法啊?还有倒装时主从句的谓语动词该怎么变?
但是千万不要是那种超级学术型的回答啊,我看那个有点晕的

举例说明
1.对现在时的虚拟
If i were you ,i would do it at once.= Were i you.i would do it at once.
If he lived with us ,he would help us out (没法倒装）
2,对过去时的倒装
If you had been here yesterday ,you would have met the professor
=Had you been here yesterday,you would have met the professor
3.对将来的倒装
If it rained this week,the crops would be saved(没法倒装）
=If it were to rain this week ,the crops would be saved(=Were it to rain this week ,the crops would be saved)
=If it should rain this week,the crops would be saved(=Should it rain this week,the crops would be saved)

谁知道虚拟语气这个语法啊?还有倒装时主从句的谓语动词该怎么变? 虚拟语气、倒装句具体语法内容.另外还有什么重要的,要举例英语中的语法虚拟语气倒装非谓语独立主格关于虚拟语气倒装的语法一个虚拟语气倒装的语法问题 suggest 虚拟语气的倒装句虚拟语气表示将来的主从句结构是什么? 虚拟语气,非谓语动词和从句这三种语法现象的关联,规律,标志和特征虚拟语气``请详细说明虚拟语气`的主从句时态`` 非谓语动词位于句首时,引导虚拟语气怎么用句子中的虚拟语气和倒装句是怎么一回事在虚拟语气的从句谓语中出现 were,should,had 时,可以省略if,同时把这个词放到句首,形成倒装.
