英语语法——虚拟语气
虚拟语气“315”
姓名:_________ 年级: _____________
语气的定义
语气是以动词形式表现出来的语法特征，它表示说话人对事物所持的态度。
(1)陈述语气
用来陈述事实的，有肯定，否定，疑问或感叹等形式。
She is very clever.
What fun it is to swim in the lake!
Why don’t you join an English language club to practice speaking English?
(2)祈使语气
用来表示请求，命令或劝告等。
Don’t be late for the meeting.
(3)虚拟语气
表示所说的内容与事实不符，不是事实或是不可能发生的，只是一种愿望，建议或与事实相反的假设等。
It is demanded that we should get everything ready by tonight.
You shouldn’t have made such kind of mistakes, for I have told you for several times.
It’s time that we began the meeting.
(一)三种情况需要用“(should) + V原”表虚拟语气
I:由于这些动词本身隐含说话者的主观意见，认为某事应该或不应该怎样，这些词语后面的“that”从句应用虚拟语气，且均以“should+动词原形”表示这种语气，但事实上“should”常被省略，故此从句中谓语动词用原形，常用的此类动词有：
表示“要求”的：ask, desire, request, demand, require, beg
表示“提议、劝告、建议”的：move (提议),propose, suggest, recommend, advise, vote 表示“决定、命令”的：decide, order
表示“主张”的：maintain, urge
表示“同意、坚持”的：consent, insist
例如：The doctor suggested that he (should) try to lose his weight.
He insisted that we (should) tell him the news.
但注意：在insist 后的从句中, suggest, insist不表示建议或坚持要某人做某事时，即它们用于其本意暗示、表明、坚持认为时，宾语从句用陈述语气。
She insists that she is right.
Your pale face suggests that you are ill.
这些词可体现在不同的名词性从句中，例如：
①I advised that we (should) go out for a walk. 宾语从句
②It is advised that we (should) go out for a walk. 主语从句
③My advice is that we (should) go out for a walk. 表语从句
④It is my advice that we (should) go out for a walk. 同位语从句
总结：以上的用法中，都涉及到运用包含以下意义的动词，形容词或名词：愿望、建议、请求、命令、可能、适当、较好、迫切、紧近、重要等。
II:“It is necessary that…”句型
用在advisable, appropriate, desirable, essential, fitting, imperative, important, impossible, necessary, obligatory, proper 等形容词之后的that分句,例如:
It is necessary that we (should) have a walk now.
It is essential that all the facts be examined first.
It was appropriate that this tax be abolished.
III: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。
例如：I never thought that he should be such a brave young soldier.
(二)有一种情况为情态动词后接have done可以表示虚拟语气
1.would have done 1.本想/打算做某事却没做
2.should/ought to have done 2.本应该做某事却没做
3.shouldn’t/oughtn’t to have done 3.本不该做某事却做了
4.could have done 4.本能够做某事却没做
5.would rather have done 5.宁愿过去做了某事却没做
6.had better have done 6.最好过去做了某事却没做
7.needn’t ha ve done7.本不必做某事却做了
区别：以下三个是对过去的推测，而非虚拟。
1. must have done 过去肯定发生了…
2. might have done 过去可能发生了…
3. can’t/ couldn’t have done过去不可能发生…
(三)五种情况下，需要将从句中的动词时态倒退一步，表示虚拟。
注意：“be”动词在虚拟语气中，不论主语是什么都需要改成“were”
If I were you, I should wait till next week.
He spoke to her as if she were deaf.
Though the whole world were against me, I would do what I consider as right.
I.I wish… / if only…
I wish it were spring in my hometown all the year around. (事实上不可能)
I wish I hadn't wasted so much time. (事实上已浪费了)
I wish it would stop raining. (事实上雨还在下着呢)
If only I were not so nervous. (要是不那么紧张就好了)
If only I knew her address. (我要是知道她的地址就好了.)
II.I would rather/ would prefer/ had rather + 别人做某事
would rather, would sooner, had rather, would (just) as soon, would prefer（希望）也用来表达主观愿望，它们之后的宾语从句中需用虚拟语气。谓语动词用过去式表示现在或将来，用过去完成式表示与过去事实相反。表示“宁愿做什么”或“对过去做的事的懊悔”。
I would rather he came tomorrow than today.
John would rather that she had not gone to the party yesterday evening.
To be frank, I'd rather you were not involved in the case.
注意：①若某人愿自己做某事，would rather后用动词原形
I would rather stay at home today.
②would rather...than...中用动词原形
I would rather stay at home than go out today.
III.It is high time…
注意：在“ It’s （high/ about）time + that 从句”中, that 从句的谓语动词要用虚拟语气，表示“是该……的时候了”，其形式为一般过去时或“ should + 动词原形”，但should 不能省略。如：
It’s time that we began our meeting.
It is high time that we should tell him the truth.
VI.as if/ as though…
在as if / as though 引导的状语从句表示的是非真实情况时，从句的谓语动词要用过去时或过去完成时。如：
She talked about the film as if she had really seen it. (Actually she didn’t see the film)
She talks as if she knew everything. (Actually she doesn’t know everything.)
V.If引导的条件状语从句表示与现实相反
真实条件句：If it rains tomorrow, I will stay at home.
对现在的虚拟：If I had a billion, I would/should/could build a school.
(In fact, I don’t have.)
对过去的虚拟：If I had left a little earlier, I would/should/could have caught the early bus.
(In fact, I didn’t catch the bus.)
对将来的虚拟：If I came/ were to come/ should come tomorrow, I would/should/could let you know.
(In fact, I won’t come tomorrow.)
小结:非真实条件句/虚拟条件句
表示说话人的意愿、假设、猜测或建议。虚拟语气不表示客观存在的事实，谓语动词用特殊的形式表示虚拟语气。
①表示与现在事实相反时的谓语形式。
从句主句
过去式(be和were) would (should、could)+ 动词原形
②表示与过去事实相反的谓语形式。
从句主句
had + 过去分词would (should、could) + have +过去分词
③表示与将来事实相反的谓语形式。
从句主句
动词过去式
should + 动词原形
would (should、could) + 动词原形
were to + 动词原形
虚拟条件句的三种特殊用法
①错综时间条件句：
当虚拟条件从句中的谓语动词和主句中的谓语动词发生的时间不一致时，主句和从句的谓语动词应根据实际的时间选用适当的动词形式。如：
If you had earned enough money，you would live a happy life in the future.
（从句与过去事实相反，谓语动词用过去完成时；主句与将来事实相反，谓语动词用“ would/sh ould/could/might+ 动词原形”。）
If you had followed my advice, you would be able to finish the work now.
（从句说明过去，主句说明现在。）
If I were you, I would have gone to her birthday party.
（从句说明现在，主句说明过去。）
If you hadn’t lent me some money, I couldn’t have bought the new h ouse and most likely I would be still living in the dangerous house now.
（从句说明过去，主句说明过去和现在。）
②含蓄条件句：
在虚拟语气中，有时假设的情况并不是以条件状语从句的形式表示，而是通过相应的介词、连词或上下文来表示，如without, but for, or, but, otherwise 等。
But for your help, we couldn’t have finished the task in time.
（= If you hadn’t helped us… tomorrow…）
What would I have done without you?
(条件暗含在分词短语without you中)
It would be easier to do it this way.
(条件暗含在不定式短语to do it this way中)
This same thing, happening in wartime, would lead to a disaster.
(条件暗含在分词短语happening in wartime中)
But for your help we couldn’t have succeeded in the experiment.
(暗含条件是but for your help)
He must have the strength of a hippopotamus, or he never could have vanquished that great beast. (暗含条件是连词or)
I would appreciate a little of your time.
(可能暗含if you were so kind as to give me a little of your time)
Alone, he would have been terrified. (暗含条件是if he were alone)
We would have succeeded. (可能暗含if we had kept trying)
Your reputation would be ruined. (可能暗含if you should accept it)
③省略if的虚拟条件句：
在if 引导的虚拟条件句中，如果条件状语从句位于句首，且从句中含有were, had 或should, 则可以省略if, 并用倒装结构。如：
Should it rain tomorrow, we would have to stay at home.
(= If it should rain tomorrow…)
Had I seen the film, I would have discussed it with them last night.
(= If I had seen the film…)
Were I a bird, I could fly freely.
(= If I were a bird…)
Should it rain next week, the farmers would have a good harvest.
(= If it should rain next week,…)

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。
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．。
高三年级英语语法-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。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）

2012届高考英语二轮专题总复习语法部分虚拟语气 表示说话人所说的话不是事实，而是一种假设、愿望、怀疑或推测。 虚拟语气在if条件从句中的使用 【观察】 If I were you, I would go to bed early tonight. 如果我是你，我今晚就会早点睡。If you took the bus, you would be late for the film. 如果你坐公车去看电影，那么你就会迟到。 If Jack had scored that goal, we would have won the football match. 如果杰克射进了那个球，我们就会赢得那场足球比赛。 If she hadn’t come, I might have been in trouble. 如果她没来，我可能已陷入困境了。 I could help you if you had difficulty in doing your homework. 如果你做作业有困难，我会帮助你的。 If it were to rain tomorrow, they would not go out. 如果明天下雨的话，他们就不会出去。 【归纳】 注意：若从句中的谓语动词是be动词的话，一律用were。 【实践】 1.If he my advice, he wouldn’t have lost his job. A. followed B. should follow C. had followed D. would follow 2. 翻译：如果我有足够的钱，我会周游世界。 If I had enough money, I would travel around the world. 翻译：如果明天见到他，我会邀请他到我家。 If I should see / were to see / saw him tomorrow, I would invite him to my house. 虚拟语气用于条件状语从句时，可以转换成下列形式： （1）省略if, 用“were, had, should + 主语”。如： Were she my daughter, I wouldn’t allow her to study abroad. 如果她是我女儿，我就不让她出国学习了。 Had I worked hard, I would have surely succeeded. 如果我当时努力学习的话，我肯定会成功的。 Should there be a meeting tomorrow, I would come. 如果明天有会议，我会来。 （2）含蓄条件句。虚拟语气句中不出现if 条件句，而是用介词、介词短语或连词通过上下文表现出来，这时须根据句子的含义判定是用虚拟现在式还是虚拟过去式。常见短语有：but for, without, otherwise, or 等。如：

高中英语语法讲解--虚拟语气 1. 语气的定义和种类 （1）语气的定义 语气是动词的一种形式，它表示说话人对某一行为或事情的看法和态度。 （2）语气的种类 A. 陈述语气 表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。 We are not ready. Did it rain all day yesterday? 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.
大学英语语法-虚拟语气
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.

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?

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。

If I had enough money, I would go to the zoo with you. If I had had enough money, I would have gone to the zoo with you. If I should have enough money, I would go to the zoo with you.
