第七章虚拟语气
语气是一种动词形式，用以表明说话人对行为或事物的看法或态度。虚拟语气表示说话人的主观态度、假设、猜测、建议、命令、甚至是与事实相反的空想等。
一、时态转换法
1.虚拟条件句：条件句有两类，一类是真实条件句，句中假设的情况是可能发生的，谓语通常都用陈述语气；第二类是虚拟条件句，表示纯粹假设的情况或是发生的可能性不大的情况。
a. 表示与现在事实相反，其条件从句用did，表示结果的主句用would/should + do．动词是be时，单数和复数人称都用were。
If I knew the answer, I would help you solve the problem now．
如果我知道答案，我现在就会帮助你解决这个问题。
If I were you, I would never make the same mistake again．
如果我是你，我永远也不会再犯同样的错误。
If there were no air, there would be no life on the earth．
如果没有空气，地球上就不会有生命。
If I knew German, I would read the book in the original.
如果我懂德文，我就要看这本书的原著了。
What would you do if you were in his place?
要是你处在他的位置，你会怎么办？
b. 表示与过去事实相反，其条件从句用had + done, 表示结果的主句用would/should + have done．
If it had not rained heavily, we would have visited the museum．
如果那时没有下大雨，我们就参观博物馆了。
If he had adopted a correct method, he would have succeeded．
如果他采取了正确的方法，他就成功了。
If they had made full preparation, they would not have failed．
如果他们准备很充分，就不会失败了。
c. 有时条件从句的动作和主句表示的动作，发生的时间并不一致，这时要根据表示的时间调整谓语动词的形式，也叫做混合虚拟式。
You would not feel so sleepy this morning if you had gone to bed early last night．
如果昨晚你早点睡觉的话，今天早晨就不会觉得困了。
If you had started earlier, you would not be in such a hurry now.
如果你早点出发的话，现在就不用这么匆忙了。
d.在这两类虚拟条件句中，主句的谓语除了用would构成外，有时还可能用might或could。在第一人称后有时也可以用should。另外，如果条件从句中包含有were, had, should,could，有时可以省略if，把这些助动词放在主语前面（这些结构在口语中较少使用）：
Had they not foreseen the danger, they would have been ambushed.
若非他们预见到这一危险，他们就会被伏击了。
Had it not been for the reservoir, we’d never have been able to beat the drought.
如果没有水库，我们绝不可能战胜这次干旱。
2.含蓄条件句
英语中有时假设的情况并非由if明确表达出来，而是通过一定的词汇手段、句子结构、上下文或其他方式暗示，这类句子通常就叫做含蓄条件句。
a．用介词短语表示虚拟条件。
With more support from the military, the design would be better．
如果军方提供更多的帮助，这个设计会更完善。
But for your assistance, we should not have succeeded．
没有你们的帮助，我们就不会成功。
The change could not have taken place without a solid industrial foundation．
没有坚实的工业基础，就不会发生日新月异的变化。
Under more favorable conditions, we could have done a better job．
如果条件更好一些，我们本可以把工作干得更好些。
b．用动词不定式表示虚拟条件。
It would be a mistake not to adopt a correct attitude towards others’ criticism．如果对别人的批评意见不采取正确的态度，那将是个错误。
It would only be foolish to ask a man like him for help．
向他那样的人求助是愚蠢的。
c．用比较级表示虚拟条件。
A more responsible person would not have left the work half done．
一个更负责的人不会让工作半途而废。
A less brave man wouldn’t have swum across the river．
一个不那么勇敢的人绝不敢横渡那条河。
d．用连接词表示虚拟条件。
I would have attended the party yesterday, but I had a cold．
昨天晚上我本想参加晚会，但是我感冒了。
I was so busy yesterday, otherwise I would have gone with you．
昨天我太忙，否则我就和你一起去了。
3.“宁可、宁愿”句型中

亨利宁愿他的房间在三楼。

I could go myself but I would sooner you went.
我自己也能去，但我宁愿你去。

从他说话的样子看，他似乎已经知道了那个秘密。

5.用在动词wish引导的宾语从句中

6.用在It is (high) time (that) …句型中
It is time that we were off．
是我们离开的时候了。
It is high time we went to the laboratory．
真到时间了。我们该去实验室了。
7.省略连词if的条件从句结构
在书面语中，虚拟或可疑条件句中的从句可以省略连词if，采用倒装语序，即将助动词提到主语前面。如果句子中没有were, had, should等助动词，则不能省略。
Were I to write the article, I should write it some other way．
要是由我写这篇文章，我会采用另一种写法。
Had you not helped me, I should have failed．
如果你不曾帮助我，我肯定失败了。

如果这趟火车开往上海该多好！
If only he had stayed with us for another week!
如果他能和我们多待一星期该多好！
二、should构成的虚拟语气
1．可疑条件句。表示对将来发生的行为怀疑或认为实现的可能性很小。条件从句用should + do, 有时也可用were to + do; 表示结果的主句要用should/
would + do。

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

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. Had you come earlier, you would have met him.
第四节虚拟语气在名词从句中的运用 一、虚拟语气在主语从句中 A.在句型“It is important (necessary, strange, natural) that .... ”中，表示某事 重要、奇怪、自然、必要等；that 后面的从句中的谓语动词用： should + 动词原形（should 可以省略）例如： It’s important that we should take good care of the patient. 重要的是我们要照顾好病人。 这类的形容词还有advisable（可取的），appropriate（适当的），compulsary（必须的），crucial （关键的），desirable（理想的），essential（必要的），imperative（迫切的），important(重要的)，possible（可能的），preferable（更好的），probable（可能的），strange（奇怪的），urgent（急迫的），vital（极为重要的）等。 B. 在It is demanded/suggested/ordered/required/recommended/requested/required/. that-clause句型中从句用(should )+动词原型，表示愿望，建议，请求等主观意愿等。 It is demanded that we should work out a plan. C. 在It is a pity/a shame/ no wonderproposal/recommendation/suggestion/surprise/advice that…..句型中从句也常用(should )+动词原型,表示建议，命令，请求，道歉，怀疑，惊奇等。 It’s a pity that you (should) miss a good chance. 二、用于宾语从句 用于表示命令、建议、要求等一类词后面的宾语从句。 insist, suggest, order, command, advise, propose, require, request, demand, desire etc. 注意：suggest 当表示“暗示、表明“讲时，insist 表示”坚持认为“之意时，应用陈述语气。 The teacher suggested that we should clean the blackboard after class. 老师建议我们课后把黑板擦了。 The smile on his face suggested that he was satisfied with our work. 他脸上的表情表明他对我们的工作很满意． He insisted that all of us be there on time by any means. 他坚持要求我们大家想尽办法按时去那里。 The man insisted that he had never stolen the money. 那个人坚持说他没有偷钱． 三、用于表语从句和同位语从句 在suggestion / proposal / order / plan / advice / idea / request /desire/ recommendation/resolution 等名词后的表语和同位语从句中要用“should＋动词原形” should可以省略． My advice is that you should practice speaking English as often as possible. 我的建议是你要尽可能经常地练习说英语。 The suggestion that the mayor should present the prizes was accepted by everyone. 每个人都接受由市长颁发奖金这一建议。 第五节虚拟语气在其他从句中 1. 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．

2020年高考英语虚拟语气语法讲解 语法讲解：虚拟语气一、语气的定义和种类 l. 语气：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（1）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。如：we are not ready. 我们没准备好。what a fine day it is！多好的天气啊！（2）祈使语气：表示说话人的建议、请求、邀请、命令等。如：open the door， please.请打开门。（3）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. 如果我是你，我就学英语了。may you succeed！祝您成功！二、虚拟语气在条件从句中的用法条件句有两类，一类是真实条件句，一类是虚拟条件句。如果假设的情况是有可能发生的，就是真实条件句。在这种真实条件句中的谓语用陈述语气。如： if it doesn't rain tomorrow， we will go to the park. 如果明天不下雨，我们就去公园。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. 如果他昨天见到你，他会问你这件事的。（事实上他昨天没见到你，因此也未能问你这件事。）在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气。现将虚拟条件从句和主句的动词形式列表如下：从句主句与现在事实相反动词的过去式（be的过去式一般用were） would/ should/ could/ might + 动词原形与过去事实相反 had + 过去分词 would/ should/ could/ might + have + 过去分词与将来事实相反动词过去式，should + 动词原形，were to + 动词原形 would/ should/ could/ might + 动词原形注：主句中的should只用于i、we，但在美国英语中，should常被would代替；从句中的should 可用于各种人称。 l. 表示与现在事实相反的假设和结果。如：if my brother were here， everything would be all right. 要是我哥哥在这儿，一切都没问题了。 2. 表示与过去事实相反的假设和结果。如：if you had taken my advice，you wouldn't （couldn't） have failed in the exam. 如果你按照我的建议去做，你一定不会（不可能）考试不及格。 3. 表示与将来事实可
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 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。 ①“wish + 宾语从句”表示不能实现的愿望，译为“要是……就好了”等。表示现在不能实现的愿望，从句中的谓语动词用一般过去时；表示将来不能实现的愿望，从句中的谓语动词用“would/could + 动词原形”；表示过去不能实现的愿望，从句中的谓语动词用“had + 过去分词”或“could(should) + have + 过去分词”。如： I wish it were spring all the year round. I wish I had known the answer. I wish I could fly like a bird. ②在表示建议、要求、命令等的动词suggest、advise、propose、demand、require、insist request、command、order等后的宾语从句中，谓语动词用should + 动词原形或是动词原形。如： She suggested we (should)leave here at once. The doctor ordered she should be operated. （2）虚拟语气在同位语从句和表语从句中的运用。
