虚拟语气
英语有两种语气——陈述语气和虚拟语气。陈述语气表示事实上发生的事情或客观存在的情况。虚拟语气表示假定、想象、愿望等非事实观念。
Ⅰ.虚拟语气在条件句中主要有以下几种情况。
(1).表达与现在的事实相反的假设或想象：
条件从句主句
If + 主语+ 过去式，主语+ should/would + 动词原形
If + 主语+ were，主语+ would/should + 动词原形
(其中，should用于第一人称，would可用于各个人称。)
If I had enough money, I should/would buy a camera.
If I were rich, I would help the poor.
(2).表达与过去事实相反的假设或想象：
条件从句i f + 主语+ had + 过去分词，
主句If + 主语+ had + 过去分词，主语+ should/would have + 过去分词
If I had had enough money, I would have bought a car.
（= I didn’t have enough money, so I didn’t buy it.）
If it had not rained yesterday, we should have gone fishing.
(3)表达与将来事实相反的假设或想象，有三种形式：
①条件从句主句
If +主语+ should + 动词原形，主语+ should/would + 动词原形
(表示可能性极小“万一”)
If it should rain tomorrow, I would not go.
注意：if从句的动词形式不分人称与数，一律用“should+动词原形”
②条件从句主句
If +主语+ were to + 动词原形，主语+ should/would +动词原形
If I were to go abroad, I would go to America. 倘若我要出国，我就到美国。
③条件从句主句
If +主语+动词过去式，主语+ should/would +动词原形
If he went to the party, he would be disappointed.
(4)在条件状语从句中，常会出现主句所表示的行为所发生的时间与从句表示的行为的时间不一致，叫做错综时间虚拟条件句，即条件从句与主句所指时间不一致。如从句指过去，而主句却指现在或将来，此时应根据具体的语境，结合上面提到的三种基本类型对时态作出相应的调整。
If you had gone to bed early last night, you would not be so sleepy now.
If I were you, I wouldn’t have gone to the party last night.
(5)假设情况不用if从句来表示，而是用without, but for, otherwise, or, but等表示一种含蓄条件。表示与现在或将来相反，用“would (should, could, might)+动词原形”；表示与过去相反用“would (should, could, might)+have+过去分词”
I knew my uncle did have no time. Otherwise he would have kept me company to go hiking.
例1：We ______ John's name on the race list yesterday but for his recent injury. (2011·江西卷28)
A. will put
B. will have put
C. would put
D. would have put
例2: I ______ through that bitter period without your generous help. (2011·陕西卷22)
A. couldn't have gone
B. didn't go
C. wouldn't go
D. hadn't gone
(5)条件从句if的省略：当从句中有were，过去分词had, 或should时，if经常省略。此时，主语后面的主动词（were，had，should等）被移至句首。
Were I a bird, I would fly to you.
= If I were a bird, I would fly to you,
Should it rain tomorrow, I would not go there.
= If it should rain tomorrow, I would not go there.
例:______ in your position, I would go.
A. If I
B. Were I
C. If was I
D. If I am
Ⅱ用在从句中的虚拟语气
⒈宾语从句中的应用（1）wish后的宾语从句：
表示与现在事实相反的愿望，从句谓语用一般过去时或过去进行时；
表示与过去相反的愿望，从句谓语用过去完成时；
表示将来没有把握或不太可能实现的主观愿望，常用“would (could)+动词原形”。
I wish I knew the answer to the question..
I wished I hadn’t spent so much money.
I wish it would stop raining.
I wish you would come soon.
例：—Where are the children?
—I wish they ______ always late. (2011·北京卷28)

B. hadn't been
C. wouldn't be
D. wouldn't have been
(2) 在具有愿望、请求、建议、命令等主观意愿的动词(desire, demand, advice, insist, require, suggest, propose, order, recommend, decide …) 后的宾语从句中需用虚拟语气。谓语动词用(should) +动词原形。值得注意的是，如果宾语从句的动词是否定的，否定词not的位置应在动词之前，而不是动词之后。
I demand that he (should) answer me immediately.
The head nurse insisted that the patient not be move.
【注意】
(1)suggest 意为“表明，暗示”时，宾语从句不用虚拟语气.
His pale face suggested that he was in poor health.
(2)insist 意为“坚持认为，坚持说”时，宾语从句不用虚拟语气。
He insisted that he did not kill the boy.
2. 主语从句中的应用It is+形容词/ 名词/ 过去分词+ that引导的主语从句，主语从句中谓语动词常用“should + 动词原形”。
常用形容词有：necessary, important, essential, imperative, urgent, preferable, vital, advisable等常用名词有：duty, pity, regret, no wonder, shame等。
常用过去分词有：demanded, suggested, required, requested, ordered, decided等
It is suggested that pupils (should) wear school uniforms.
It is important that everyone (should) inform themselves of these rules.
It is a pity that he (should) refuse to accept the offer
3.表语从句中的应用上述动词相应的名词形式作主语+连系动词构成表语从句，要用虚拟语气，即“should + 动词原形”.常用名词形式有：advice, decision, demand, proposal, request, order, suggestion等。
His suggestion was that the meeting (should) be put off.
Ⅲ其他形式的虚拟语气
1. 在It's (high/about) ti me “该干某事了” 之后的定语从句中需用虚拟语气。谓语动词用过去式. It is high time that you went to school.
2. 虚拟语气在as if / as though 引导的方式状语从句中的应用（谓语动词形式与wish后的宾语从句基本相同）
表示与现在事实相反，从句谓语用一般过去时或过去进行时；
表示与过去事实相反，用过去完成时；
表示将来的可能性不大，用“would (could)+动词原形”
He felt as if he were responsible for what had happened.
He treats me as if I were a stranger.
3.if only 引起的感叹句中需用虚拟语气
表示与现在或未来事情相反的愿望，谓语动词用过去式或would/should+动词原形

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
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．
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.
【The Subjunctive Mood】 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。 陈述语气(indicative mood),表示所说的话是事实。 祈使语气 (imperative mood),表示所说的话是请求或命令。 虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或及事实相反的假设等。 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及非真实条件句(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，句中的条件从句及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，句中的条件从句及结果主句皆须用虚拟语气。
1. 及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. 及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. 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。）

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
高中虚拟语气精讲 英语动词有三种语气，陈述语气，祈使语气和虚拟语气。 定义：用来表示说的话不是事实，或者是不可能发生的情况，而是一种 愿望，建议，假设的语气叫虚拟语气。 ●虚拟语气在条件状语从句中的用法。 假如我有足够的钱, 我就去环游世界. If I had enough money, I would travel around the world. 假如我是你, 我就不会说那样的话.

If you had followed the teacher’s advice, you wouldn’t fail the exam now. ●假设条件虚拟倒装。条件从句中有should，were，had三个助动 词可以把if省略，并将这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up. If it were not for your advice, we couldn’t have got over the difficulties. Were it not for your advice, we couldn’t have got over the difficulties.

Otherwise, I couldn't have afforded the trip.我父母借钱给我了。否则，我可付不起这次旅费。（虚拟） Shut the window, otherwise it'll get too cold in here. （非虚拟） I'm lucky that I'm interested in school work, otherwise I'd go mad.

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。
虚拟语气 一、语气 英语动词有三种语气， 陈述语气，祈使语气和虚拟语气. 二、虚拟语气的定义 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，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。 【即学即练】 单项填空 If the weather had been better ，we could have had a picnic.

高二英语虚拟语气讲解 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。 直陈语气(indicative mood),表示所说的话是事实。 祈使语气 (imperative mood),表示所说的话是请求或命令。 虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。 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。 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 与将来事实可能相 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，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。）
虚拟语气 虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句及与将来事实相反的虚拟条件句。具体情 例句： （1）表示与现在事实相反 If I had enough money now, I would lend it to you. （2）表示与过去事实相反 If he had taken your advice, he wouldn’t have made such a bad mistake. （3）表示与将来事实相反 I would go shopping with you if it were to be Sunday tomorrow. 1. 虚拟条件句的倒装 在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。例如： Had I been（= If I had been ）in that situation，I would not have let the thief escape away with so much money. Should there be （= If there should be） a drought，what should we do at that time ？ 2. 错综时间条件句 有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。例如： If we hadn’t been working hard in th e past few years ，things wouldn’t be going so smoothly. 3. 含蓄条件句 有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。这种句子称为含蓄条件句。例如： But for the help from you ，I would not have had the chance to go to college. 二、虚拟语气在某些从句中的运用 在某些词或短语后接的从句中要使用虚拟语气，表示愿望、建议或命令等。根据虚拟语气的形式不同，虚拟语气可以分为“should类”和“过去时态类”。 （一）should类 这一类的虚拟语气是通过从句中的谓语动词使用“should +动词原形”体现出来的，should 可以省略。其具体运用体现在： 1. 在suggest ，order，demand ，propose，command，request，desire，insist等表示建议、命令、要求、意见的动词后接的宾语从句中要使用虚拟语气。
