虚拟语态的形式
1、对现在的虚拟：(直接用动词的过去时....)
if I did /were.... I would.......
2、对将来的虚拟：if ..were to..I would....= if ..did...I would....
(此项与对现在的虚拟相同，但对现在的虚拟不用were to.
要区别对将来的虚拟和对现在的虚拟``一般句子里面都有时间标志``)
(If it were to rain tomorrow,we would not go out.
=If it rained tomorow,we would not go out.)
3、对过去的虚拟 If I had done....I would have done....
(If I had known the answer, I would have told you.)
(至于If ..had been done...would have done
前面的been只是因为是被动语态```所以要看句子的具体意思````)
固定句型的补充。
要用虚拟语态的句子:
I would rather I could......(I would rather she could not come here)
if only..(但愿....)
A:I will go to Korea next month.B:If only I could go with you
虚拟语态表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设，推测，命令，建议，要求等。
虚拟语态的基本结构
(1). 与现在事实相反的假设：一般过去时(be用were)，主句结构{ should(would)等+动词原型}
例如：If they were here ,they would help you.如果他们在这，会帮助你的。
(2). 与过去事实相反的假设：过去完成时主句结构：{should(would)等+have+过去分词}
例如：If he had come yesterday,Ishould(would)have told him about it.如果他昨天来的话，我会把这件事告诉他的。
(3). 表示对将来不大发生的事的假想。一般过去时，were+不定式，should+动词原形;主句结构：{should(would)+动词原形。
例如：If you succeeded ,everything would be all right.如果你将来成功了一切都会好的。
