高中英语虚拟语气语法总结在高中英语语法中，虚拟语气是一个重要的语法点。

在许多情况下，虚拟语气被用于表达假设、愿望和不可能的状态等。

本文将为大家总结高中英语中常见的虚拟语气语法。

一般现在虚拟语气（Present Subjunctive）一般现在虚拟语气通常用于表达虚构的情况或假设的情况。

具体来说，当主句谓语是“would rather”、“it’s time”、“if”、“suppose”、“lest”、以及“as if/though”时，从句中的谓语动词需要使用一般现在虚拟语气。

举个例子： - I would rather he (be) here with me. 我宁愿他现在和我在一起。

（此处的“be”使用了一般现在虚拟语气） - If I (find) his phone number, I would call him. 如果我找到他的电话号码，我就会打电话给他。

（此处的“find”使用了一般现在虚拟语气） - Don’t speak lest she (should) hear you. 不要说话，唯恐她听到。

（此处的“should”是虚拟语气的标志）需要注意的是，虽然一般现在虚拟语气的形式和一般现在时相同，但是在一些情况下，虚拟语气需要加上“should”或“were”等词汇来表示。

过去虚拟语气（Past Subjunctive）过去虚拟语气通常用于表达假设的情况或虚构的情况。

在从句中，虚拟语气的形式由过去式或过去分词构成。

主句通常使用“could”、“would”或“might”等词汇，有时也可以使用过去时态来表示虚拟情况。

举个例子： - If Mary (had) known you were in hospital, she would have come to see you. 如果玛丽知道你住院了，她一定会去看望你的。

（此处的“had”使用了过去虚拟语气，表示假设的情况）需要注意的是，过去虚拟语气的使用非常灵活，要根据实际情况来判断是否使用虚拟语气。

例句：- It is important that he be present at the meeting.（建议）- I suggest that he should go to the doctor.（建议）- They insisted that he leave the room immediately.（命令）2.表达愿望、请求、要求：-主语+动词过去式；- 主语+would/could/might + 动词原形；- 主语+动词过去式+宾语+should + 动词原形。

例句：- I wish I could fly.（愿望）- I would appreciate it if you could help me.（请求）3.表示虚拟条件：- If条件从句中的谓语动词用过去完成时，主句用would/should/might/could + have + 过去分词；- If条件从句中的谓语动词用过去时，主句用would/should/could + 动词原形。

例句：- If I had known his phone number, I would have called him.（虚拟条件）- If you had listened to me, we could have finished the project earlier.（虚拟条件）4.表达建议、要求、祝愿：- If only内部称述 + 主语 + 过去式。

）Wouldn't life be boring if we had everything we wanted? （如果我们想要什么就有什么，生活岂不是很无聊？）2. 与过去事实相反条件从句：If + 主语 + had + 过去分词主句：主语 + would/should/could/might + have + 过去分词例句：If I had known your phone number, I would have called you. （如果我知道你的电话号码，我就给你打电话了。

虚拟语气（1）——倒推时态类定义：虚拟语气是一种动词形式，有两种意思 1.表示说话人所说的不是事实，而是一种假设、猜测、怀疑等（非真实条件状从和让步状从）2.表示说话人的愿望、要求、命令、建议（名词性从句：主宾表同）使用情景 1.用来表达一个假设或纯粹的意愿（与事实相反或不太可能实现）（如果我是宇航员，我要在月球上跳舞）2.用来缓和语气，使句子更委婉、礼貌、得体（如果你能接受我的邀请，我将不胜感激）3.表示烦恼、不耐烦等情绪（你要是能考上大学，全家都烧高香了）4.表示适度的责备或批评（如果你那时更耐心点，现在我们都成功了）5.表示美好的祝愿或祝福（祝你成功）1.虚拟条件句一般虚拟条件句混合虚拟语气（错综时间条件句）定义：条件状语从句表示的行为和主句表示的行为发生的时间不一致例子：If you had followed my advice, you would be better now.如果那时你听了我的建议，现在已经好了If it hadn’t been for you, I would have to make another trip there tomorrow.如果不是你的话，我明天还要再走一趟。

If you had studied hard before,you would be a college student now.如果你以前努力学习的话，你现在就是大学生了。

省略+倒装当虚拟条件句的谓语动词中含有were，should，had时，if可以省略，并将were,should,had提前于句首，变为倒装句。

如果虚拟条件句是否定句，not 保留在原处If he should agree to go there, we should send him there.= Should he agree to go there,we should send him there.If she were there,she would agree with us.= Were she were, she would agree with us.If he had learnt about computers,we would have hired him.= Had he learnt about computers,we would have hired him.含蓄虚拟条件句定义：有时为了表达的需要，在虚拟语气中并不总是出现if引导的条件状语从句，而是通过其他手段来代替条件从句分类：1) but for....=(If it+be not for) ；without；Without your help ,we couldn’t have finished the work ahead of time.= But for your help,we couldn’t have finished the work ahead of time.= If it hadn’t been for your help,we couldn’t have finished the work ahead of time.没有你的帮助，我们不可能完成任务。

虚拟语气表示动作或状态与事实相反，或不可能发生的情况。

一．虚拟语气用于条件状语从句中1. 表示与现在事实相反或不可能发生：条件状语从句：一般过去时（虚拟语气中be→were）主句用：would(should, could, might)+动词原形。

Eg:If we had time now, we would read it again.If I were you, I would work hard.2. 表示与过去事实相反或不可能发生：条件状语从句：had+过去分词；主句：would(should, could, might)+have+过去分词。

Eg:If he had taken my advice, he would have succeeded in the test.If I had known your telephone number then, I would have called you.3. 表示与将来的事实可能相反或不可能发生：条件状语从句：①一般过去时②should +动词原形③were to+动词原形；主句：would(should, could, might)+动词原形。

Eg:If it should rain, the crops would be saved.If it were to snow tomorrow, they would not go out.注：虚拟条件句的特殊情况(1)混合/错综型虚拟语气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，称为‘错综条件句’，动词的形式要根据它所表示的时间作出相应的调整。

Eg:If you had followed my advice, you would be better now.(从句说的是过去，主句是现在)Eg:If I were you, I would have taken his advice.(从句是现在，主句是过去)(2)省略if的虚拟语气如果从句中含有were/ should/ had时，则可以把这三个词置于句首，省略if.采用倒装语序。

高中英语虚拟语气语法规则总结在英语中，虚拟语气是对事实的虚构或非现实条件的表达。

如果条件句是虚拟的，主句需要使用“would/should/could/might”等情态动词：* 如果我有机会，我会去环游世界。

1. 对现在或将来不可能实现的愿望：* 我希望我会说流利的法语。

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。

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。
