虚拟条件从句中谓语动词用一般过去式,主句用“would/should/might/could+动词原形”形式,表示对现在不可能实现情况的假想。虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略,再把were, should或had 移到从句句首,实行倒装。需要注意,在虚拟语气的从句中,动词'be'的过去时态一律用"were",不用was, 即在从句中be用were代替。
虚拟条件句往往指不能实现或纯假想的情况,可以对过去、现在或将来进行假想。虚拟语气的本质就是对根本不可能的情况发生假设。
例句:
(1)Were they here now, they could help us.=If they were here now, they could help us.
如果他们现在在这里,就能帮助我们了。
(2)Had you come earlier, you would have met him.=If you had come earlier, you would have met him.
如果你早点来,就能遇见他了。
(3)If I were you, I would go to look for him.
如果我是你,就会去找他。
(4)If he were here, everything would be all right.
如果他在这儿,一切都会好的。

虚拟条件句分类:
1、对现在情况的虚拟
条件从句中谓语动词用一般过去式,主句用“would/should/might/could+动词原形”形式,表示对现在不可能实现情况的假想。
If I were you,I would choose to work in a small town.
如果我是你,我会选择在小城镇工作。(事实上我不是你)
2、对过去情况的虚拟
条件从句中谓语动词用过去完成式,主语用“would/could/should/might+have+动词的过去分词”形式。
If it had not been for your help yesterday,I could not have caught the bus.
如果昨天没有你的帮助,我不会赶上公交车。(事实是你昨天已经帮助了我,所以我赶上了车)
3、对将来情况的虚拟
在表示与将来事实相反的条件从句中,谓语动词可用should do,were to do或动词的过去式三种形式表示,但意义略有不同。should表示的可能性最大,动词过去式的可能性次之,were to do 的可能性最小。
If things were to be twice,all would be wise.
假如凡事都可以重新做一次,人人皆可成为聪明人。(事实是并不是所有的事都可以重新做一次)
