高中英语语法-虚拟语气全总结
高中英语语法-虚拟语气全总结虚拟语气通常用于表达与现实相反的假设情况。
在非真实条件句中，虚拟语气的形式有两种：与现在事实相反的假设和与过去或将来事实相反的假设。
与现在事实相反的假设通常使用if+主语+助动词的过去式（如were。
did。
had）+动词原形，主句则使用XXX动词原形。
例如：If I had time。
I would XXX。
如果我有时间，我会参加会议。
与过去或将来事实相反的假设则有三种形式：①if+主语+动词过去式；②if+主语+wereto+动词原形；③if+主语+should+动词原形（注意不能是would）。
主句同样使用XXX动词原形。
例如：If you had taken my advice。
you would not have failed in the exam。
如果你听了我的建议，你就不会在考试中失败了。
在错综时间条件句中，动词形式要根据表示时间的状语从句作出相应的调整。
另外，在条件句中可以省略if，把were、had、should提到句首，变成倒装句式。
例如：Were I at school again。
I would study harder。
如果我还有上学的机会，我会更加努力研究。
Had you arrived earlier。
you would have caught the bus.If it rains tomorrow。
XXX climbing.What would you do with a n dollars?We couldn't have finished the work ahead of time without your help.Otherwise。
I would have taken part in the sports meeting.XXX me of your birthday。
or else I would have known nothing about it.A man who s drinking water would be dead in about seven days.I might have been XXX assistance。

高中英语虚拟语气语法总结高中英语虚拟语气语法总结一、引言在高中英语语法中，虚拟语气是一个重要的知识点。
掌握虚拟语气的用法不仅可以提高英语表达的准确性和流畅性，还可以帮助理解许多英语文学作品的深层次含义。
本文将详细介绍高中英语虚拟语气的用法及其在句子中的应用。
二、语法总结1、虚拟语气的使用虚拟语气在英语中表示一种假设或非真实的条件，通常用于表达建议、愿望、假设或怀疑等。
根据不同的情境和表达需要，虚拟语气有多种形式，下面列举几种常用的虚拟语气表达方式：1、与现在事实相反：If I had time, I would go for a walk.2、与过去事实相反：If he had known the answer, he would have replied.3、与未来事实相反：If it were to rain tomorrow, we would stay at home.4、表达建议或请求：If it were you, I would choose the blue dress.2、语气助词的运用虚拟语气在句子中的运用常常与特定的语气助词结合。
以下是几种常见的语气助词及其功能：1、if条件从句：用于表达条件或假设，如上述例子所示。
2、Otherwise：用于表达相反的情况或假设，例如：Otherwise I would have told you the truth.3、Otherwise：用于表达相反的情况或假设，例如：Without your help,I would not have achieved this success.3、句子结构与语法规则虚拟语气的句子结构及其语法规则对于正确使用非常重要。
以下是几个需要注意的要点：1、主句和从句的时态关系：在含有虚拟语气的句子中，主句和从句的时态通常是不一致的，以表达假设或非真实的情况。
2、主谓结构：虚拟语气的主谓结构通常与陈述语气的结构不同，特别是当从句表达非真实的情况时，主谓结构需要进行相应的调整。

虚拟语气在非真实条件句中①错综时间条件句:当条件状语从句表示的行为和主句表示的行为所发生的时间不一致时，被称为错综时间条件句，动词的形式要根据它表示的时间作出相应的调整。
如：If you had followed my advice just now, you would be better now.If you had studied hard before, you would be a college student now.②if省略句在条件句中可以省略if, 把were, had, should提到句首，变成倒装句式。
如：If I were at school again, I would study harder.→Were I at school again, I would study harder.如果我还有上学的机会，我会更加努力学习。
If you had come earlier, you would catch the bus.→Had you come earlier, you would catch the bus.如果你来得早点，你就能赶上公共汽车。
If it should rain tomorrow, we would not go climbing.→Should it rain tomorrow, we would not go climbing.如果明天下雨的话，我们就不能登山去了。
③用介词代替条件状语从句常用的介词有with, without, but for。
如：What would you do with a million dollars? (=if you had a million dollars)如果你有100万元，你会做什么？We couldn’t have finished the work ahead of time without your help. (=if we hadn’t got your help) 没有你的帮助，我们不可能提前完成这项工作。
Without your help, we couldn’t have finished the work ahead of time.= But for your help, …= If it had not been for your help, …= Had it not been for you help, …没有你的帮助，我们不可能提前完成这项工作。
④含蓄条件句有时在虚拟语气中并不总是出现if引导的条件句，而是通过其他手段来代替条件句。
如：I was ill that day. Otherwise, I would have taken part in the sports meeting. (副词)He telephoned to inform me of your birthday, or I would have known nothing about it. (连词)A man who stopped drinking water would be dead in about seven days. (定语从句)I might have given you more help, but I was too busy. (连词)Everything taken into consideration, they would have raised their output quickly. (独立主格结构) ⑤even if, even though也可用于虚拟语气，其形式与if 从句在虚拟语气中的形式相同。
