虚拟语气讲解虚拟语气语气和时态、语态一样，是动词的一种形式，表明说话的目的和意图。

英语中有四种语气：陈述语气、疑问语气、祈使语气和虚拟语气。

陈述语气：表示谓语动词所表达的动作或状态是符合客观事实的，也就是把动作或者状态当做事实表达出来或者提出一种看法。

疑问语气：用来提出问题或询问情况的语气。

祈使语气：用来向对方提出请求、邀请，给予忠告、指示、警告、命令等的语气。

祈使句中的主语You一般省略，动词也用原型表示。

虚拟语气：把动作当做一种只存在于讲话人想象中的“假设”或“推测”，而不是当作客观事实中的真实事件。

它表达的通常是怀疑、忧虑、推测、想象或祝愿。

这里主要讲解虚拟语气的一般语法特征和难点。

一、虚拟语气在条件句中的用法条件句分为两种：一种是可能实现的，一种是无法实现的，可能实现的条件句叫真实条件句，不能实践的就是虚拟条件句。

1. 真实条件句：这种条件句实现的可能性非常大。

这类条件句常用if, unless, once, as long as等引导。

Eg. If you have any doubts about our plan, I’ll stop it. 如果你对我们的计划有怀疑，我会立刻终止它。

The secretary will get a pay raise as long as she does her job well. 这个秘书会得到加薪，只要她好好工作。

2. 虚拟条件句：往往指不能实现的或者纯假设的情况，可以对过去、现在或者将来的情况进行假象。

在这三种情况中，主句和从句中的动词也有不同的形式。

A. 与现在情况相反：表示对当前不可能实现的情况的假想，此时从句用一般过去式(did sth./ were...)，主句用过去将来式（would/ shoud/ could/ might do sth.）：Eg. If I were you, I would choose to work in a small town. 如果我是你，我会选择在小镇工作。

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。

虚拟语气语法讲解语法讲解--虚拟语气英语中有三种不同的语气：陈述语气，祈使语气和虚拟语气。

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。

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。

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。

If it should rain, the crops would be saved.If it were to snow tomorrow, they would not go out.P.S 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。

If you had followed my advice, you would be better now.(从句说的是过去，主句是现在)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。

虚拟语气定义：虚拟语气用来表示说话人的主观愿望或假想，不是事实或与事实相反。

陈述语气祈使语气动词的语气非真实条件句中的虚拟语气名词性从句中的虚拟语气虚拟语气特殊句型中的虚拟语气虚拟语气需特别注意的情况用法：一．IF引导的虚拟句式注意；混合虚拟（1）不同时间的虚拟：If he had listened to me, he would not be in trouble now.If he had told me yesterday, I should know what to do now.(2) 虚拟与陈述的混合：He could have passed the exam, but he wasn’t careful enough. You should have come earlier, the bus left a moment ago.二．名词性从句中的虚拟语气:从句谓语动词(should) +do1.主语从句：it is + adj + that结构2.宾语从句：主语+要求接虚拟语气的动词+that一个坚持：insist两个命令：order; command 两个决定：decide; determine三个建议：suggest; advise; propose四个要求：demand; ask; request; require注意：① suggest：暗示；insist：坚持说(不虚拟)② except, believe, think suspect等动词的否定形式或疑问句后面的宾语从句要用虚拟。

I never thought that he should be such a brave young solider③ should竟然I am glad that your novel should have won the first prize.④ wish引导从句的虚拟语气，谓语动词变化和if从句虚拟语气一样。

虚拟语气虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一。

虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。

Ⅰ用以表示虚拟条件的虚拟语气虚拟条件句的三种基本类型:1.与现在事实相反。

若与现在事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”：If you took a taxi，you’d get there quicker.如果你坐出租车去，你可以快一点到那里。

(但你不坐)If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。

(可惜我不知道)2.与过去事实相反。

若与过去事实相反，条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, could, might)+have+过去分词”：If I’d left sooner，I’d have been on time.要是我早点动身，我就准时到了。

(但我动身太迟了)If we had found him earlier we could have saved his life. 要是我们当时早点找到他的话，我们就可以救活他。

(可惜我们找到他太晚了)3.与将来事实相反。

若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”：If he went，would you go too? 如果他去，你也去吗?(大概他不会去)If I asked him，I’m sure he’d help us. 如果我向他提出要求，肯定他会帮助我们。

(不过我不打算这样做)大多数的虚拟条件句属于上面三种情况的一种，但并不排除存在条件和后果中，一个和现在情况相反，另一个和过去情况相反，例如：If you had followed what the doctor said, you would not have been so painful now.这个句子在高中出现频率颇高。

虚拟语⽓⽆论从形式上还是时态上都⽐较复杂，需要归类记忆。

虚拟语⽓⼤体分为三类：(1) be型虚拟(2) were型虚拟(3) if 条件句及主句虚拟下⾯会详细说每种虚拟形式的特征和规律，考试时先判断属于哪种虚拟类型，剩下的皆是套路~（1）be型虚拟（基本是套路）形式：should + 动词原形，should可以省略⽤法：1）表⽰“命令、建议、要求”等意义词语之后的宾语从句⽤be型虚拟，常见的词如下: demand, desire, insist, order, ask, command, propose, recommend, suggest, prefer, require, request等最常见的形式是这类动词后⾯接着⼀个宾语从句，则宾语从句的谓语部分要⽤（should）+ 动词原形来虚拟例: We demand that the meeting（should）be postponed.The manager suggested that we (should) work together.注意：有时候你所见到不⼀定是上述动词引导的宾语从句，⽽是由上述词变体后所引导主语从句(it做形式主语，如：it is advised/ suggested/ requested/ ordered/ proposed that…)、表语从句或同位语从句例如：It is required that the students (should) learn a foreign language. (主语从句) The requirement is that all the equipment in the meeting room (should) be checked twice before. (表语从句)We didn’t stand for his proposal that the meeting (should)be postponed. (同位语从句)只要看到句中有上述动词或其变体，不管词性怎么变、句型怎么变，都⽤be型虚拟！特例：suggest和insist这两个⽐较特殊，当suggest作“暗⽰、表明、说明”讲，insist作“坚持说”讲，后⾯⼀般跟的是客观事实，不需要虚拟~这是⼀个⽐较重要的考点，体会下⾯两组句⼦：We all suggest that a lab (should) be built. 我们都建议建⼀个实验室。

If the doctor had come last night, the boy would have been saved. （可倒装）1.3 将来事实不一致，句型为：If should were to 主语＋＋do ，主语＋should （could ，would, 或might ）＋do. If it should rain tomorrow, we would stay at home.（可倒装）If I were to go to the moon one day, I could see it with my own eyes.（可倒装） If you missed the film to night, you would feel sorry.（混合虚拟）难点：①在条件句中如果出现were, had, should 可省去if ，将主语与这些词倒装 Had the doctor come last night , the boy would havesaved.Were I to go to the moon one day , I would see it with my own eyes.Should it rain tomorrow , we would stay at home.②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”，常常表现为if+过去虚拟+主句现在虚拟If you had followed my advice, you would be better now.If you had studied hard before, you would be a college student now.2. wish 后面的宾语从句中与现在愿望不一致: 主语＋did ； I wish I were you.与过去愿望不一致: 主语＋had ＋done ；I wish I had visited the white House when I was in the states.与未来愿望不一致: 主语＋would （could ）＋do 。

虚拟语气讲解一. 简介虚拟语气用来表示说话人的主观愿望或假想,而不表示客观存在的事实,所说的是一个条件,不一定是事实,或与事实相反。

虚拟语气通过谓语动词的特殊形式来表示。

英语中的语气分为陈述语气、祈使语气、虚拟语气三类。

二. 应用条件虚拟语气常在表示条件和结果的状语从句中。

在表示与事实相反的虚拟语气时动词有三种时态:现在时,过去时,将来时,过去完成时,现在完成时。

在条件句中的应用:条件句可分为两类,一类为真实条件句,一类为非真实条件句。

非真实条件句表示的是假设的或实际可能性不大的情况,故采用虚拟语气。

虚拟语气在什么情况下用虚拟语气? 在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气,表示主观愿望或表示某种强烈情感时,也用虚拟语气。

即当一个人说话时欲强调其所说的话是基于自己的主观想法,而不是根据客观实际,就用虚拟语气。

三. 虚拟语气在非真实条件状语从句中的用法1、真实条件状语从句与非真实条件状语从句真eg . If he doesn’t hurry up, he will miss the bus. 如果他不快点,他将错过巴士。

( 真实条件状语)(不是虚拟语气)If he is free, he willask me to tell stories. 如果他是空闲的,他会要求我讲故事。

(真实条件状语)(不是虚拟语气)非真eg. If I were you, I would go at once.如果我是你,我马上就会去。

(非真实条件状语从句)If there were no air, people would die. 如果没有空气,人就会死亡。

(非真实条件状语从句)2、用法及动词形式1、表示与现在事实相反的情况:if+主语+过去时+其他+主语+should/would/could/might+do+其他例: 1.If I were you, I would take an umbrella.如果我是你,我会带把伞。

高考英语语法复习虚拟语气知识讲解一、基础知识（一）什么是虚拟语气谓语动词的作用不仅可以表示动作的时间、状态、假设（情感），也是一种语气（mood)的表现形式，表明说话的目的和意图。

（语气包含陈述语气、祈使语气、虚拟语气、疑问语气）虚拟语气用于表示假设、愿望、建议、命令等非真实或虚拟的情况，即与真实相反。

上学的时候老师经常举的一个例子，"If I were you"因为我不可能是你，这是一种不可能存在的事实，所以这是个虚拟语句。

总而言之英语中的虚拟语气可以分为两大体系：一是表示与事实相反的，或者是假象的情形，通常由if引导，叫做虚拟条件句；另一个体系是在名词从句中使用虚拟语气，表示建议，命令或者要求等语气，类似于上述美剧常用的台词。

（二）虚拟语气的用法这一部分我们主要用虚拟语气在条件句中的用法作为讲解不同情况条件从句谓语主句谓语使用场景与过去事实相反If+主语+haddone主语+should/would/could/might+have done既然是过去了，那么谈到的一切情况都已既成事实，所以过去虚拟表达的是一个与过去事实相反的情形与现在事实相反If+主语+did(be动词用were)主语+should/would/could/might+do既可能是事实，也可能是假设条件。

因此，假设条件句和事实相反句适用于谈现在的情况与将来事实相反If+主语+ did(be动词用were)If+主语+ wereto + doIf+主语+should+ do主语+should/would/could/might+do对于将来时间的虚拟不可能以事实为基础，而只能是表达说话人的一个设想或愿望。

所以，对于将来的虚拟只适用于假设条件句，而不可能表达一个与事实相反的虚拟与现在事实相反：If I had a map, I would lend it to you.如果我有地图我就借给你。

（但我没有）与将来事实相反：If I were to do the job, I would do it in a different way. 要是我来做这工作，我会是另一种做法。

虚拟语气一、考点聚焦1、虚拟语气用于条件状语从句中（1）表示与现在事实相反的假设，条件状语从句中的谓语动词用“过去式（be动词的过去式用were）”，而主句中的谓语动词用“would / should/ could / might + 动词原形”。

如：If I were a boy, I would join the army.If the had time, she should go with you.（2）表示与过去的事实相反，条件状语从句中的谓语动词用过去完成时，主句中的谓语动词则用“would / should / might / could + have +过去分词”。

如：If he had taken my advice, he would have succeeded in the competition.（3）表示与将来事实相反，条件状语从句中的谓语动词一般过去时或should(were to) + 动词原形，而主句中的谓语动词则用would / should/could might + 动词原形。

如；If it were to rain tomorrow, the football match would be put off.（4）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，动词的形式要根据它所表示的时间作相应调整。

如：If they had worked hard, they would be very tired.(从句说的是过去，主句指的是现在)Were I a boy, I would join the army.Had he taken my advice, he would have succeeded.Were it not for the expense, I would go to Britain.2、虚拟语气用于名词性从句（1）虚拟语气在宾语从句中的运用。

②i wish i could pass the examination.我希望我能通过考试。

③may you succeed!祝您成功！虚拟语气在语法里算得上是个难点。

让我们就从最简单的开始吧。

第二部分：简单句中的虚拟语气一、情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌、或委婉的语气，常用于日常会话中。
