英语虚拟语气讲解

英语虚拟语气讲解

语气(mood)是一种动词形式，用以表示说话者的意图或态度。英语中的语气有三种：陈述语气、祈使语气和虚拟语气。

一. 虚拟语气在条件句中的应用

虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果主句皆须用虚拟语气。

条件从句主句

与现在事实相反

If 主语+动词过去式（be的过

去式用were）

Should would, might，

could+动词原形

与过去事实相反If 主语+had+过去分词should would, might，

could）+ have ＋过去分词

与将来事实相反If 主语+动词过去式（be的过去

式用were）；should＋动词原

形；were to＋动词原形

should（would, might，

could）+动词原形

1. 与现在事实相反的虚拟条件句，

If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。

（事实是：天在下雨，我们不能出去野餐。表示愿望。）

If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。

（事实是：他没来这，他不可能帮助你。表示对他的良好印象。）

2. 与过去事实相反的虚拟条件句如：

She would have gone to the party if she had been invited.

要是当初她被邀请的话，她就会去参加这次聚会了。

（事实是：当时没有人邀请她，因此，她没有来参加聚会。表示后悔。）If she hadn't called me, I would have overslept this morning.

今天早上，她要是不叫我的话，我就会睡过头了。

（事实是：她今天早上叫我了，我没有睡过头。表示感激。）

3. 与将来事实可能相反的虚拟条件句，

If I were to be twenty years old next year, I would take the course of French.

明年我要是二十岁，我就会学法语。

（事实是：我现在已经老了，明年我学不了法语了。）

If it should fail, I would try again.要是失败了，我会再试一次。

（事实是：有可能失败，可我会再试。表示未知。）

*虚拟过去式有时并不表示“不大可能实现的假设”，而是表示一种希望或不希望发生的动作。如：

If we caught the early train, we’d get there by lunch time.

假如我们赶上早班火车，到午饭时间我们就会到达那里了。(表希望)

4. 混合型的条件句

当条件从句与主句所表的时间不一致时，虚拟语气的形式应作相应的调整。主句和从句的谓语动词并不相互呼应，这种条件句叫混合条件句。较多见的混合型条件句是从句用过去完成时（指过去行为），而主句用一般时（指目前状态）。

He would pass the test if he had taken my advice．如果他听了我的劝告，他现在会通过考试。

If I had spoken to him yesterday, I should know what to do now.

假如昨天我对他说了，现在我就知道该怎么办了。

You would be much better now if you had taken my advice.

假如你接受了我的意见，你现在就会好得多。

二. 连词if的省略

如果虚拟条件句的谓语部分有were，had和should时，可省略if，把were，had和should放到从句主语前面去，多见于书面语。

Had you not helped me，I should have failed.要是没有你的帮助，我就失败了。

Were you in my position, you would do the same. 假如你处在我的地位，你也会这样干的。

Should they attack us, we’ll wipe them out com pletely.

假如他们进攻我们，我们就把他们彻底消灭干净。

三. 含蓄条件句

虚拟条件句中的条件从句有时不表出来，只暗含在上下文中，这种句子叫做含蓄条件句。含蓄条件句大体有三种情况。

1) 条件暗含在短语中。如：

But for your help we couldn’t have succeeded in the experiment.

如果没有你的帮助，我们的实验是不会成功的。(暗含在分词短词but for your help)

What would I have done without you? 如没有你，我会怎么办呢？(条件暗含在介词短语without you 中)

It would be easier to do it this way. 这样做会比较容易。(条件暗含在不定式短语to do it this way中)

This same thing, happening in wartime, amount to disaster. 同样的事，如发生在战时，就会酿成大祸。(条件暗含在分词短语happening in wartime 中)

He must have the strength of a hippopotamus, or he never could have vanquished that great beast. 他一定是力大如河马，否则他绝不会击败那只庞大的野兽。(暗含条件是连词or)

Alone, he would have been terrified. 如是单独一人，他是会感到害怕的。(暗含条件是alone)

2) 条件暗含在上下文中。如：

You might stay here forever. 你可以永远待在这儿。(可能暗含if you wanted to)

We would have succeeded. 我们本来是会成功的。(可能暗含if we had kept trying)

Your reputation would be ruined. 你的名誉会败坏的。(可能暗含if you should accept it)

四. 不用if引导的条件从句

虚拟条件句中的条件从句除用if引外，还可用when, unless, lest, suppose, as if, for fear, in case, on condition 等词语来引导。如：

The peasants prepared to feed the city when it should be freed. 农民已准备在这座城市解放后供给粮食。

Lest you should not have heard all, I shall begin at the beginning. 我怕你没有听全，所以我再从头开始讲一遍。

Unless I were well, I wouldn’t be at school. 除非我好了，否则我不会上学。

Suppose you were given a chance to study in America , would you accept? 假如给你一个到美国学习的机会，你会接受吗？（suppose 或supposing =what if）

Supposing it were so？（=Supposing it were so，what would happen？）要是这样的话，会怎么样呢？

He can use the bicycle on condition that he should return it tomorrow如果明天能还回来，他就可以借用这辆自行车。

In case I forget , please remind me of my promise 如果我忘了，请提醒我的诺言。

Susan is walking slowly ,as if she were tired. 苏珊走得很慢，就像是累了似的。

与if一样，上述词语所引导的条件从句亦可用直陈语气，表可能实现或发生的事。

虚拟语气还可用于主语从句、宾语从句、表语从句、定语从句等。

1. 虚拟语气在主语从句中的应用

“常用在It is (was)+形容词/ 过去分词+that引导的主语从句”的句型中的主语从句要用虚拟语气。主语从句的谓语用should+动词原形(或should+have+过去分词)或只用动词原形(尤其是美国英语)。should在此是助动词，本身并无实义，这种主语从句中的should有时有感情色彩。

It's important that we（should）work out a plan. （带有“要求”的含义）It's better that he go at once. （带有“建议”的意思）

☆用于本句型的形容词并不多，常见形容词有：necessary，important，best, right, impossible，preferable，desirable, imperative, advisable，essential，reserved，urgent，等。

It is necessary that he（should）be sent there at once．

It's strange that he should say so.

I was glad that he should go.

It is important that we should speak politely.

It is a pity that she should fare so badly.

It's right that you should think that way.

☆用于本句型中的过去分词就是表示提议要求、命令等动词的过去分词，如suggested，settled, required，requested，demanded，urged，decided, proposed，ordered，desired，advised等。

It is requested that Professor Liu（should）give us a lecture．

It is desired that we（should）get everything ready by tonight．

I’m ashamed you should have done such a thing.

It has been suggested that the meeting（should）be put off．有人建议推迟会议。

It is settled that you leave us, then?

注意：这种句型中的主语从句也可用陈述语气，如：It was important that he made an explicit statement on this score last week. 他上个星期对于这一方面做了明确的说明，这是很重要的。

2. 虚拟语气在宾语从句中的应用

1). 宾语从句在表示提议、要求、命令、意志等动词后，其谓语用should+动词原形或只用动词原形的虚拟语气，作为suggest，request，demand，urge，propose，prefer，advise，insist，require，order，command，maintain，ask，object, arrange, desire等动词的宾语。如：

The doctor suggested that he not go there．

He suggested that we should leave early.

The judge ordered that the prisoner should be remanded. 2). wish的宾语的从句，表示愿望，常省去连词that。

注意：wish与hope接宾语从句的区别在于：hope表示一般可以实现的希望，宾语从句用陈述语气。wish表示很难或不大可能实现的希望,宾语从句用虚拟语气。试比较：

（1）We hope they will come,(We don’t know if they can com e.)

（2）We wish they could come,(We know they are not coming.)

3). would rather, would sooner等表示愿望，其宾语从句常用虚拟过去式。

☆表示与现在和将来含义事实相反的虚拟语气要用动词的过去式

☆用过去完成式(had + 过去分词)表示过去事实相反的含义

I would rather you came tomorrow.我宁愿你明天来。

I’d sooner she left the heavy end of th e work to some one else.我宁愿她把重活留给别人。

4). 有些动词，如think, expect, believe,其否定式的宾语从句亦可用should+动词原形。如：

I never thought he should refuse.我万没有想到他会拒绝。

She did not expect that you should come.她没有预料你会来。

3. 虚拟语气在表语从句中的应用

名词suggestion，proposal，order，advice，demand等作主语，其后的表语从句中的谓语动词一般使用虚拟语气，用should +动词原形或省略should。

My suggestion is that we (should) send a few soldiers to help them.

我的建议是我们应派几个战士去增援他们。

My advice is that you (should) treat her well.我的忠告是你应该善待她。

He makes the demand that she (should) leave the place at once.

他提出一个要求，要求她立刻离开这个地方。

My suggestion is that we should tell him.我的建议是我们应该告诉他。

Our only request is that this should be settled as soon as possible.

我们唯一的请求就是尽快解决这个问题。

注意：虚拟语气也可以用于同位语从句。

如：There was a suggestion that Brown should be dropped from the team.有一项建议是布朗应该离队。

五、虚拟语气的几种特殊用法

1.省掉if的条件从句倒装结构：

Had you asked me, I would have told you. (=If you had asked me,…)

2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从

句来表示，如：

A true friend would not do such a thing.

(=If he were a true friend, he...)

(=If there were no w ater,…)

(=If you hadn’t helped me,…)

3.虚拟语气用于定语从句:It’s (high) time that…+动词过去式或should+动词原形，(should不能省略,be用were)"来表示,意为"(现在)该……"。如：It’s time (that) you had a hair cut.

It’s high time (that) we took some action.

4.虚拟语气用于if only引导的感叹句:

If only I had taken his advice.我要是听他的话就好了。

If only I were a bird!我如果是一只鸟就好了。

5.虚拟语气用于简单句

1)表示说话人谦虚、客气、有礼貌,使语气委婉,常出现在日常会话中。例如:

It would be better for you not to stay up too late.

Would you be kind enough to open the door?

2)用于一些习惯表达法中。例如:

Would you like a cup of tea.

You had better go now.

3)用"may+动词原形",表示"祝愿"、"但愿"。may须置于句首。例如:

May you be happy!

May you succeed!

6.含蓄条件句

在某些虚拟语气结构中没有if条件句,虚拟条件是用其它形式表示出来,这种现象在语法上称为"含蓄条件句"。含蓄条件具体分为以下几种情况:

1)通过动词不定式短语表示条件。例如:

You would be a fool to refuse his offer.

(=If you should refuse his offer,you would be a fool.)

要是你拒绝他的建议,就太傻了。

2)通过介词短语表达条件。例如:

But for the storm I would have arrived much earlier.

(=If it had not been for the storm...)

要不是那场暴雨,我早就到达了。Without air, there would be no living things.

I would not have succeeded but for your help.

3)通过连词otherwise,or,but,that,though,once等表达条件。例如:

She came to town yesterday,otherwise/or I would not have met her.

昨天她到城里来了,不然我就不会遇见她了。

(otherwise/or=if she hadn't come)

I would have attended the meeting,but I have been too busy.

(=...if I had not been too busy)

我本来要参加会议的,只是太忙了。

4)通过Were it not for...或Had it not been for...等句式表达条件。意为"如果当时没有……",表示同过去事实相反的假设。例如:

Were it not for(=If it were not for) the leadership of the Party,we could not live a happy life.

要不是党的领导,我们不可能过幸福生活。(与现在事实相反)

Had it not been for(=If it had not been for) the leadership of the Party,we should have failed.

若不是有党的领导,我们早就失败了。(与过去事实相反)

5)通过分词短语表达条件。例如:

Given more attention,the trees could have grown better.倘若给予更多的关心,这些树本来可以生长得更好的。

(=If they had been given more attention...)

6)无词句暗示条件。例如:

Such mistakes could have been avoided.这种错误本来可以避免的。

(暗含条件从句if we had been more careful)

It was so quiet,you could have heard a pin drop.是那样的安静,掉根针你都听得见。

(暗含条件从句if it had dropped to the ground)

高中英语虚拟语气详细讲解大全

高中英语虚拟语气详细讲解 虚拟语气 什么是虚拟语气？是的，我们要学习虚拟语气就必须先弄明白它的概念。 虚拟语气包含两种：一种指与事实相反或不可能发生。“虚拟条件句+虚拟主句”的结构都属于这一类；even if、even though、as if、as though引导的状语中如果需要用到虚拟语气也属于这一类；wish、would rather后面接的宾语从句表示不可能实现的愿望，还是属于这一类。 另一种指与事实实际是否发生没有直接关系。如和suggest、order、demand等表示建议、命令、要求等相关的名词性从句都属于这一类。 大家知道以上两类虚拟语气后，我们就从从句的角度来系统学习虚拟语气。紧跟小简老师的步伐哦！ 一. 虚拟条件句中的虚拟语气 1、表示与现在事实相反的情况 从句：If+主语+did(be动词用were) 主句：主语+ should/would/might/could+do

If I were you,I would take an umbrella. 如果我是你，我会带把伞。（事实：我不可能是你） If I knew his telephone number,I would tell you. 如果我知道他的，我就会告诉你。（事实：不知道） If there were no air or water,there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水) 2、表示与过去事实相反的情况 从句：If+主语+had+done 主句：主语+should/would/might/could+have done If I had got there earlier,I should/would have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） If he had taken my advice,he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话） 3、表示与将来事实相反的情况

高中英语语法虚拟语气教学：The subjunctive mood 厦门第十中学吕瑞珠 一、概述 本节课是高中英语语法教学课，授课内容为虚拟语气，授课对象是高三年学生。从呈现、加深记忆、巩固到实践并将语言项目运用于写作中并做适当的点评，大概需要两课时。但我这里着重阐述的是第一课时的教学内容、教学策略等。 通过本节语法教学课的学习，学生重新整合自己的有关虚拟语气的知识，复习已知的虚拟语气的表达形式如：I wish I could fly freely in the sky like a bird; It is high that you got up.等等，并学习新的表达形式如：The English teacher suggested that we should read the English newspaper every day; I would have passed the English exam if I had worker harder in the past 20 days.最为重要的是，学生在学习完虚拟语气的表达形式后，要在写作中运用。 虚拟语气在高中英语语法的难点之一，多数学生感到费解，因此也更需要老师的指导与相应的实践与运用，并且较好地掌握虚拟语气的表达形式，有助于扫除学生阅读过程中对个别句子的理解。 二、教学目标分析 1．知识与技能 1）复习学生已掌握的虚拟语气表达的句型： I wish I were… / I could … It is high time that you did your homework.. If I were you, I would… 2) 学习虚拟语气新的表达方式，尤其是if引导的虚拟条件状语从句，掌握与现在事实、与过去事实、与将来事实相反的三种虚拟语气的表达，特别是主句与从句时态的呈现；还有引导出的宾语从句需要运用虚拟语气的动词，如suggest, insist, propose, demand and so on. 3）培养学生运用所学知识表达自己的思想的能力。 2．过程与方法 1）引导学生在欣赏英文歌曲An Angel的情景教学过程中，开启对虚拟语气表达已有的知识记忆。

虚拟语气用法总结及详细解析

虚拟语气用法 英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。 1、表示动作或状态是客观存在的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句中。 China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句) 2、祈使句表示说话人对对方的请求、警告，建议或命令。如: Please come over here. 请到这边来。 Watch your steps! 当心!(走路) 3、虚拟语气表示说话者做出的假设而非事实，或难以实现的情况，甚至表达彻底相反的概念。此外，如需表达主观愿望或某种强烈的感情时，也可用虚拟语气。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如: If I were a bird，I would be able to fly in the air. 如果我是一只小鸟，我就能在空中飞行。 I wish I could pass the examination. 我希望我能通过考试。

If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪，我们就不能去滑冰了。 If she were to be here next Monday, I would tell her about the matter. 如果她下周一来这儿的话，我就会告诉她这件事的始末。 4、有时，虚拟条件句中，结果主句和条件从句的谓语动作若不是同时发生时，虚拟语气的形式应作相应的调整。这种条件句叫错综条件句。 ①从句的动作与过去事实相反，而主句的动作与现在或现在正在发生的事实不符。 If I had worked hard at school, I would be an engineer, too.如果我在学校学习刻苦的话，我现在也会成为一个工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。 ②从句的动作与现在事实相反，而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话，我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话，他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时，if可以省略，这时条件从句要用倒装语序，即把were, should, had等词置于句首，这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话，我们就派他去。 Were she here, she would agree with us.如果她在这儿的话，她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话，我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句，否定词not应置于主语之后，而不能与were，should，had 等缩略成Weren't，Shouldn't，Hadn't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏，我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time，I would come. 假若我有时间，我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来，暗含在副词、介词短语、上下文或其他方式表示出来，这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中，如without…, but for…,otherwise（要不是因为）等 But for his help, we would be working now. (要不是他的帮助，我们还会在工作呢。

高中英语虚拟语气详解和练习(含答案解析)

虚拟语气 第一节语气 英语的动词一般可带有三种不同的语气：陈述语气（Indicative Mood），祈使语气(Imperative Mood)和虚拟语气（Subjunctive Mood）。不同的语气用动词的不同形式（有的还借助句法形式）来表示。 第二节虚拟语气的概念 虚拟语气是一种特殊的动词形式，一是用来表示说话人所说的话不是一个事实，而是一种假设、猜测、怀疑等(在条件从句中或让步状语从句中)；一是表示说话人的愿望、要求、命令、建议等 (在宾语从句、表语从句、同位语从句)。 第三节虚拟语气在条件句中 １．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所表示的时间作出相应的调整． If you had followed my advice , you would be better now. 如果你听我的建议，你现在就会痊愈了． ２．在条件句中，可省略 if，把were ,had, should 提到句首，变为倒装句式． If you had come earlier, you would have met him.

It is (high / about ) time that…从句中的谓语动词用过去式或should＋动词原形，should 不能省略．

英语虚拟语气语法归纳总结

虚拟语气: 表示说的话不是事实，不可能发生或者说可能性很小的情况，表达一种愿望、建议、假设。 if were/did, would do if had done, would have done if were to do/should do, would do 举例： If I were you, I would do nothing about it.

(popularization 普及，publicity 宣传) Without your help, I would have failed. We’ll go earlier, otherwise we wouldn’t get a seat.（表示可能性小）

英语虚拟语气讲解

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。 但是，如果后果用了虚拟语气，而条件却用陈述语气，这种用法是错的。 2. 除了表示虚假条件外，if从句还可以表示对将来的推测，由于是 将来还没有发生的，所以谈不上是真实的还是虚假的，只能说这个事情 发生的可能性有多大。一般情况下，可以用陈述语气的if从句来表示对

高中英语语法(虚拟语气)

Unit13虚拟语气专题讲解 【知识要点】 语气（mood）是一种动词形式，用以表示说话者的意图或态度。 英语有三种语气： ＊直陈语气（indicative mood）---- 事实 France lies to the east of England. ＊祈使语气（imperative mood）---- 请求、命令 Make yourself at home. ＊虚拟语气（subjunctive mood） If there were no air and water , we should not be able to live on the earth. 虚拟语气表示说话人的一种主观愿望或假想，所说的是一个条件而不一定是事实，或与事实相反。 一. 虚拟语气在if条件状语从句中的用法 假设类型条件从句谓语 动词形式 主语谓语 动词形式 与现在事实相反动词的过去式(be用were而不用was) should/ would /could/ might+动词原形 与过去事实相反had + 过去分词 should/ would/could /might + have+过去分词 与将来事实相反1.should+动词原形 2.动词过去式 3.were to+动词原形 should/ would/ could/ might +动词原形 1. 在错综条件句子中，虚拟条件从句和主句动作发生的时间不一致，因此，主句和从句的谓语动词应根据所指的时间选用适当的虚拟语气形式。 1）If I were you，I wouldn't have missed the film last night． 2）If he had followed the doctor's advice，he would recover already．（从句与过去事实相反，主句与现在事实相反。） 2、在if虚拟条件句中，有时可把连词省去，采用倒装语序把谓语动词were或助动词did，had，should 移到句 首构成非真实条件从句的另一种句型，其意思不变。 1）Had we time to spare，we would be glad to go to the park． 2）Were it not for the discovery of electricity，the modern world would experience great inconvenience． 3、有时假设的情况不用if引导虚拟条件从句来表述，而用介词（如without， but for等）引出的短语、分词 （如supposing等）引出的短语、并列连词（如or，otherwise，but，though等）、由动词suppose引出的祈使句或通过上下文的意思来表达。此时句中谓语动词仍采用虚拟语气的相应形式。 1）But for your advice，I would not be able to do this work． 2）Victor obviously doesn't know what's happened，otherwise he wouldn't have made such a stupid remark．。

虚拟语气用法详解 一、条件句中的虚拟语气 1. 条件句中虚拟语气的形式 从句中提出一种与客观现实不相符或根本不可能存在的条件，主句会产生的一种不可能获得的结果。条件句中 的虚拟语气根据不同的时间有三种不同的形式。 2. 条件句中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如： If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话，他就会充分 利用他的时间了。 If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。 (2) 现在时的条件句中的虚拟语气。如： If he were free, he would help us. 要是他有空的话，它会帮助我们的。 If he studied at this school, he would know you well. 如果他在这所学校学习的话，它会对你很熟悉。 (3) 过去时的条件句中的虚拟语气。如： If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。 If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿，我就会会到了李先生。 3. 运用条件句中的虚拟语气时，须注意的几个问题 (1) 当从句的主语为第三人称单数时，谓语动词若是系动词be 时，可用was 代替were。但在倒装虚拟结构及if I were you, as it were 中，只能用were。如： Were I ten years younger, I would study abroad. 要是我还年轻十岁的话，我会去国外学习。 If I were you, I would try my best to grasp the chance. 要是我是你的话，我要尽力抓住这次机会。 (2) 有时，虚拟条件句中，主、从句的动作若不是同时发生时，须区别对待。①从句的动作与过去事实相反，而主句的动 作与现在或现在正在发生的事实不符。如： If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话，我现在也会使工程师了 If they had informed us, we would not come here now. 如果他们通知过我们的话，我们现在就不会来这里了。

You wished she would arrive the next day.(would + arrive) 你希望她第二天会到。(事实上她还没到) Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。它仅有两个形式，即be型虚拟式和were型虚拟式。 Be型虚拟]----- be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。其主要用法如下： 1)用于表命令、决定、建议、坚持等词语之后的that分句中 这一用法又分三种情况： a)用在 decide,decree,demand,insist,move,order,prefer,propose,recommend,request,require, suggest,vote等动词之后的that分句中.（宾语从句） 在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。 He ordered that all the books be sent at once. He ordered that all the books be sent at once. we propose that somebody neutral take the chair. She insisted that she go to the south for her holiday. b)用在 advisable,appropriate,desirable,essential,fitting,imperative,important,impossible,nece ssary,obligatory,proper等形容词之后的that分句中。（主语从句） It is essential that all the facts be examined first.

I thousht it advisable that an armed guard stand in readiness. c)用在 decision,decree,demand,instruction,order,requirement,resolution等名词之后的that分句中。 The board has given instructions that the agent fly to Boston. We were faced with the demand that this tax be abolished. Their decision was that the school remain closed. 在这一用法中be型虚拟式能与“should+不定式”交替使用，也能与to-不定式交替使用。 He ordered that the books be sent at once . = He ordered that the books should be sent at onc. = He ordered that the books to be sent at once. 2）用于由if,though等引导的分句中.

高中英语语法-虚拟语气全总结

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
