一、if从句：（一）（二）错综时间的虚拟句：通常情况下,在条件句中主句和从句的谓语动词所指时间一致, 但有时也可能指不同的时间,这时主句和从句的动作不是发生在同一时间，其动词形式要根据时间而定。
1. If I were you, I would have taken his advice. (从句指现在, 主句指过去)。
2. If I had taken my raincoat with me this morning, I would not be wet now. (从句指过去,主句指现在)。
3. If we hadn’t been working hard in the past few years, things wouldn’t be going so smoothly.（从句指过去，主句指现在）。
4. If the weather had been more favorable, the crops would be growing still better.（从句指过去，主句指现在）。
5. If we had not got everything ready by now, we should be having a more terrible time tomorrow. （从句指现在，主句指将来）（三）省略：If 从句中含有were, should, had时，可省略if并把were, should, had提前。
例如：Were I you, I wouldn’t quarrel with him.备注：注：would, should, could与might的选择：①一般常用would，如同在真实条件句中主句常要用will一样。
常译作“将、就会”。
如：If I knew him, I would ask him for help. 如果我认识他的话，我就会向他求助。

提纲挈领谈虚拟语气的用法
提纲挈领谈虚拟语气的用法作者：黄连军来源：《中学生英语·中旬刊》 2019年第8期黄连军虚拟语气是表达说话者的某种假设、假定、主观愿望、主观想法的一种表达方式。
语气含有两种，真实语气和虚拟语气。
虚拟语气在历年高考中都占一定比例。
我在教学中把虚拟语气模块化，每一模块都有自己的“纲领”。
学生在学习中只要分好类，把握住这些“纲领”，就能轻松掌握虚拟语气的用法。
1. 用于条件句中虚拟语气的用法虚拟动词形式要和虚拟的时间保持协调一致。
把握这类虚拟的学习要领：“3统，1混，4特殊。
”（1）3统：在表示现在、将来、过去虚拟句式中，if从句的谓语动词和主句的谓语动词要保持相对统一，对将来时间的虚拟条件句动词形式:should do/did/ were to do..., 主句动词形式：would/could/should/might + do.；对现在时间的虚拟条件句动词形式:did/were...., 主句动词形式: would/might/could/should do. ；对过去或完成时间的虚拟从句和主句的动词形式条件句动词形式: had done,主句动词形式: would/could/should/might+ have done。
（2）1混： if从句是对过去或完成的虚拟假设，而主句则说明现在的虚拟情况，过去和现在时间的错位导致从句和主句的动词形式的不统一，其形式是：if从句动词形式用had done形式，主句动词形式用would/could/should/might be/be doing 形式。
如：If you had learned the sub junctive mood well when it was taught, it wouldn’t be so difficult for you now. 如果讲虚拟语气的时候你学会了，你现在就不会感到困难了。
（3）4特殊：指含蓄条件的虚拟句型。

英语虚拟语气知识点总结
英语虚拟语气知识点总结英语虚拟语气知识11、基础用法2. 注意四个情态动词的用法(1)若表示在某一假设的条件下，必然而然就会发生某事，第一人称可用should或would, 而二、三人称只用would.(2)若表示在某一假设条件下就能够干某事，各人称都用could.(3)如果表示在某种假设条件下有可能会发生某事，各人称都用might.3.虚拟语气的倒装当虚拟条件句中含有 were，had，should，could等动词时，可以将if省略，然后将 were，had，should，could等词移至句首。
注意：以上移至句首的 had不一定是助动词，如果是实义动词也可倒装：If he had money，he would buy a car. Hadhe money，hewould buy a car.(1)从句与过去事实相反相成，而主句与现在事实相反。
例如：If you had not been strict withme when I was young, I could not be such a successful person now.(这种虚拟语气的特点是主句中常含有时间准状语now或nowadays)(2)Should anyone come and ask for me, tell them I willcome back tomorrow.(主句为祈使句，条件句与将来事实相反，表示说话人认为某件事情发生的可能性很小。
)5.含蓄虚拟条件句含蓄虚拟条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。
这类用法主要见于以下七种方式：(1)将条件隐含在不定式短语中。
I should be happyto go with you. (=I should be happy if I could go with you.)(2)将条件隐含在分词短语中。
Born in bettertimes, he would have been a scholar. (=If he had been born in better times, he…)(3)将条件隐含在介词短语中。
