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.

If you had taken your teacher’s advice, you wouldn’t have made such a mistake.

If it were to/ should rain tomorrow(表示降水率很低)，they wouldn’t go shopping.

附注：

虚拟语气，条件状从倒装

状语从句中，去掉if,提前were/ had/ should

如：If I were you, I would give up.

→Were I you, I would give up

If you had taken the advice, you would have….

→Had you taken the advice, you would have…

If the world shou ld come to an end,……

→Should the world come to an end……

另外，without, but for, otherwise构成的条件状语从句中，也有含蓄的虚拟语气But for the popularization of electricity, we would lead a whole different life today. (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）

但其实，高中英语考试也常考：

错综虚拟语气条件句

即：假设条件状从发生的时间与所假设的谓语动词不一致，此时，主句和从句要根据各自的时间而定。

举例：

If our government had known better how to lay out the road construction, the traffic jam problem would not be so serious today.

(lay out 规划、设计、安排、陈设、摆放… layout n.布局、规划)

二、特殊句式：

I wish I had n’t made such an irrevocable mistake. (irrevocable不可撤销、不可以挽回的)

2.「十个词」

一坚持：insist （表示坚持主张、认为，不表示坚持说）

二命令：order, command

三建议：advise, propose, suggest （表示建议，不表示表明、显示、暗示）四要求：desire, demand, require, request (两R两D)

这些动词后面的宾语从句要使用(should +) do的形式should可省略

例：

We suggested that Tom （should）have a rest.

It’s suggested that the plan be carried out before long.

(before long, 不久之后, long before很久以前)

尝试翻译：他坚决要求我到场

同时，这些动词的名词形式构成的名词性从句（主语从句、表语从句、同位语）也要用虚拟语气

order, advice, suggestion, proposal, demand, request, desire.

例

It’s an order that the s oldiers obey the rules in the army.

My suggestion is that everyone of us three finish one part of this project and then we integrate them together. (integrate整合)

3.would rather 宁愿

I would rather you had been to the movie instead of me.

Don’t come today, I would rather you came tomorrow.

4.部分As if/though 句子好像、似乎

Tom told me this fairy tale in a manner as if it had happened for real yesterday. 5.If only……. 要是…就好了

If only she knew that it's I who sent the gift to her.

6.It’s ( about/ high) time that 是时候做……

+ 1、过去式2、should do

It's time that you went to bed.

说到这里，补充两个句式：

It is the 1st (2nd /3rd) time that … have/ has done….

It was the 1st time that … had done….

7.It’s necessary/ strange/ natural/ important/essential that…….

从句动词用(should) do

It’s essential that we master a foreign language when doing international trade and business. (essential 必要的、本质的、基本的…..)

8.情态动词+have done

would have done 本来要做

could have done 本能够做（却没做）

might have done 本来可能

should/ought to have done 本来应该做

shouldn’t/ oughtn’t to have done 本来不应该做

needn’t have done 本来不必要做

你本来不应该告诉她真相。

当时我没有足够的钱，否则我会买那本书的。

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。

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。否定句时not留在原来位置不变。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)

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．。

英语语法专项：虚拟语气用法详解及练习(附答案)

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。

可用虚拟语气的用法总结

虚拟语气的用法总结 语气：语气是动词的一中形式，它表示说话人对某一行为或事情的看法和态度。 虚拟语气表示动作或状态不是客观存在的事实，而是说话人的主观愿望，假设或推测等。如If I were you, I should study English. 一．虚拟语气在条件从句的用法 条件句有两类，一类是真实条件句；一类是非真实条件句，也就是虚拟条件句。 如果假设的情况是有可能发生的，就是真实条件句，谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果假设的情况是过去或现在都不存在的，或将来不大可能发生的，则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中，主句 If her mother had taken the doctor’s advice, she would/might have got well earlier. If it were to rain tomorrow, the match would be canceled. 有时候省略if，采用局部倒装语序。把had /should/were 等动词（不包括行为动词）移到从句的句首。例如： Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 错综时间条件句 有时条件从句的动作和主句动作发生的时间不一致，这时需要根据意思采用表示不同时间的动词形式来进行调整。 If she had taken the doctor’s advice, she might still be alive. If I were you, I would have accepted their terms. 三．含蓄条件句

What a fine day today！ B. 祈使语气 表使说话人的建议、请求、邀请、命令等。 Be careful. Don’t forget to clo se the window. Open the door, please. C. 虚拟语气 表使动作或状态不是客观存在的事实，而是说话人的主观愿望、假设或推测等。 2. 虚拟语气 一. 虚拟语气在条件句中的应用 学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。如： If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。 Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。 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。 1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should （would, might，could）+动词原形。 如： 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，条件从句的谓语用had+过去分词，主句的谓语用should （would, might，could）+ have ＋过去分词。 如：She would have gone to the party if she had been invited.

虚拟语气 1. I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。(事实上是不知道) 2. He wishes he hadn't lost the chance. 他真希望没有失去机会。(其实已失去) 3. 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. It was appropriate that thisi tax be abolished. 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.

高考英语语法难点：虚拟语气

虚拟语气(the subjunctive mood,又称假设语气,是谓语动词的一种形式,表示说话人叙述的内容与事实相反,在现实中并不存在,或实现的可能性很小。 一、动词的语气 语气用来区别讲话人对某一行为或事情的看法和态度。英语中的语气(mood有三种,分别是陈述语气、祈使语气和虚拟语气。 1.陈述语气 陈述语气一般用来叙述事实或就事实提出询问,主要用于陈述句、疑问句和某些感叹句。 Where there is a will, there's a way. 有志者事竟成。 Can you help me carry the box upstairs 你能帮我把箱子搬到楼上吗?

实用英语虚拟语气的解析及其用法讲解 在当前英语语法当中，有一些学生总结的几个难点语法，其中之一就是虚拟语气，怎样判断出句子使用了虚拟语气，是哪一种形式的虚拟语气是学生无法清楚掌握的难点。本文从虚拟语气的定义到各种形式都进行了详细的讲解和分析，并针对各种形式的用法都进行了分析和举例，讲解明白，以帮助学生们能更好地了解和掌握英语语法中这个难学的语言现象。 标签：英语虚拟语气；定义；用法；分析及举例 一、虚拟语气的定义（Subjunctive Mood） 在我们了解什么是虚拟语气前，大家首先要弄清楚英语的语气表达，也就是英语学习中我们都会用到哪些语气。英语中的语气（Mood）可以分为：1The Indicative Mood（陈述语气）；2The Interrogative Mood（疑问语气）；3The Imperative Mood（祈使语气）；4The Subjunctive Mood（虚拟语气）4类。陈述、疑问、祈使语气在本文中就不再过多阐述。而我们在这里重点讲解虚拟语气。什么是虚拟语气呢？虚拟语气用来表示假想，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。虚拟语气表示说话者所说的话并非事实，或难以实现的，甚至表达相反的概念。另外表示主观愿望或表达某种强烈的感情时，也用虚拟语气。 二、虚拟语气的判断及用法 （一）if条件状语从句中虚拟语气的判断 if条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种：1与过去事实相反的假设。结构为：从句的谓语动词用“had+过去分词”，主句用“should（would，could，might）+have+过去分词”。 2与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should（would，could，might）+动词原形”。 3与将来事实相反的假设。结构为：从句的谓语动词用“should（wereto）+动词原形”，主句用“should（would，could，might）+动词原形”。 （二）宾语从句中的虚拟语气 1wish后接宾语从句中的虚拟语气：根据从句的意义来判断 A：表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如：

虚拟语气 在英语文法中有三种语气，即直述式语气(Indicative Mood)、祈使语气(Imperative Mood)和虚拟语气(Subjective Mood)，其中前两种我们早已熟悉了，这里则不多谈了，如：How beautiful she is! 则是直述式语气，而Hurry up! Don't hurry up 则是祈使语气。我们主要来看看虚拟语气的主要用法。虚拟语气主要是用来表达一种无法实现的愿望，一种与事实相反的情况，或者将不可能实现的，或可能性很小的事实，假想为事实予以表述。这样的动词结构称为虚拟语气。它主要有三种形式，即与现在事实相反的假设，与过去事实相反的假设，与将来事实相反的假设。它们具体结构如表８－７。 虚拟语气的构成 种类条件句结构主句结构 与现在事实相反动词用过去式 be 动词用were Should/could＋动词原形 would/might＋动词原形 与过去事实相反的用had＋过去分词 Should/could＋have＋过去分词 would/might＋have＋过去分词 与将来事实相反动词用过去式 were to 加动词原形 should 加动词原形 should＋动词原形 would＋动词原形虚拟语气其他习惯用法简表 种 类 功用句型例句 虚拟语气表示主观 愿望 主句谓语宾语从句谓语动词I wish we could go to the seaside today. wish 现在过去式 过去 had+过 去分词 I wish I had gone to the basketball match. 将来 should+ 动词原 形 would+ 动词原 形 could+动 词原形 might+动 词原形 I wished I could fly to the moon.

英语四级语法 虚拟语气

虚拟语气 一．一般虚拟条件句 (1) 与现在事实相反 ——If I were you, I wouldn’t worry. ——If I had the book at hand, I would read the passage to you. 那么，虚拟语气现在时的句型为： 从句：If + 主语＋动词过去式(be 变were) +… 主句：主语＋would (should ,could ,might ) + 动词原形＋… (2) 与过去事实相反 ——If you had gone to last night’s games, you would have met him. ——If the policeman had arrived earlier, he would have seen the accident. 那么，虚拟语气过去时的结构是： 从句：If＋主语＋过去完成时… 主句：主语＋should (或would,could,might) + 现在完成时… (3) 与将来事实相反 ——If he should come tomorrow, I would give him the dictionary he needs. ——If Mr. Li were to do the experiment tomorrow, he might read the instructions carefully.

那么虚拟语气将来时的句型是： 从句：If+主语＋should (或were to )+动词原形＋… 主句：同虚拟语气现在时的主句结构。 练习： 1.I f this report were more accurate, it __________ an invaluable document. A.were B.had been C.will be D.would be (D) 2.I _______ in trouble if the police had stopped me. A.were B.would have been C.would be D.had been (B) 3.W hat would you do if war _________ out. A.breaks B.could break C.had broken out D. were to break (D) 二、在if引导的虚拟条件句中，若有were, had, should，可省去if,将were, had, should提到主语前，形成倒装。例如： ——Should there be a meeting tomorrow, he would tell you.
