虚拟语气表示说话人所说的事或话不是事实,而是一种假设,愿望,怀疑或推测。它主要用于条件从句,让步从句和名词性从句中。

一、虚拟语气在条件句中的用法:

虚拟语气常用在条件句中,表假设的情况与事实相反或不太可能实现,这种句子称为虚拟条件句。可分为下列几种情况:

(一)由if引导虚拟条件句。如:If I were you,I should study hard.如:If you had come here,you could have met my brother.这种句子的谓语动词一般分三种情况:

1、假设的条件与现在的事实相反,主从句的谓语动词应为:If主+动词过去式或were…,主+would/should/could/might+V、(原形)(主句中should 一般只用于第1人称)。如:If it were not for the smowy weather ,we would be all right.

例1、If I you,I would go with him to the party.

A、was

B、were

C、had been

D、will be

析:该句为if引导的条件句,从主语谓语看“would go”(是与现在事实相反),套用上边句型,从句谓语应为动词过去式,若是be动词应为were,所以该题答案应为B。

2、假设的条件与过去事实相反,其句子结构应为:If+主+had done…,主+would/could/should/mi ght+have done…

例2、 more careful,his ship would not have sunk.

A、If the captain were

B、Had the captain been

C、Should the captain be

D、If the captain would have been

析:该题题干部分有一谓语动词为would not have sunk,由此可知是对过去事情的虚拟,便可推出从句的谓语动词应为had done形式,再看选项,

含有had done的只有B,该题正确答案即是B。(当if引导的虚拟条件中有were,had,should时,可省略if,把were,had,should提到主语之前)。

3、与将来的事实相反或对将来的推测

从句动词用动词过去式或were to+v(原)或should+v(原),主句用would/should/could/might+v(原)如:

If there were to be meeting this tvening,I would come.如果今晚没有会议的话,我就来。

例3、If it tomorrow,we would have to put off the sport meet.

A、were rain

B、should rain

C、would rain

D、will rain

析:根据语境中的tomorrow,可知是表将来的条件句谓语可用did/werre to/should do,主句用would do根据所给选项只有B项正确。

(二)由介词without,but for等构成的短语所表示的虚拟条件如:But for the air(=If there were no air),no life on earth could have been developed.如果没有空气,地球上就不可能产生任何生命。

(三)通过上下文体现虚拟条件,句子往往有but,other

wise,unfortunately等类似转折词。如:He would gain weight but he doesn't eat enough.(=If he ate much,he would gain weight.)他本可以增加体重,但他吃得不够多。

She ran,othervvise she would have missed her bus.(=If she had not run,she would have missed her bus.)她要是不跑,就错过了这趟公共汽车了。

二、虚拟语气在名词性从句中的用法

(一)在wish后的宾语从句中,表示一种愿望,此时that常省略,从句谓语常用虚拟语气,分三种情况:

1、宾语从句表示与现在事实相反,从句中谓语用动词过去式或。如:I wish

I were with her now.

2、宾语从句表示与过去事实相反,则用“had+过去分词”。

如:I wish I had not failed in the last exam.

3、宾从表示与将来事实或不确定的将来事实相反用

would/should/could/might+v(原)。

如:"I wish you would help me to put these things away,"he said.

2、在表建议要求,命令、主张等动词如suggest(建议)advise request,demand ,order, command等词后的宾语从句中,谓语要用虚拟语气,其结构是should+v原 shoudl可省。如:I suggest that you (should) go home as soon as possible.

3、用在表语从句和同位语从句中。

如果含有表建议、命令、请求、愿望等词的相应名词如:

suggestion,advice,order,insistance作主语则表从用should+v(原)should可省,若它们后跟同位语从句也用should+v(原)如:Your suggestion that I(should)go abroad is right.

His suggestion is that we(should)have the meeting now.

4、用在would rather,had rather等后的宾从中谓语动词应用过去时或过去完成时。如:

I would rather you were not here.

I'd rather you had been present.我宁愿你当时在场。

5、用在It is important/mecessary/…或It's a pity等结构中的主语从句中。如:It is important that the TOEFL office(should) confirm your registration.

三、用于其它从句中的虚拟语气

1、在as if/as though从句表不可实现的事。如:

I love her as if/though she were my daughter.

2、It is(high)time that主+ v过去式/should+v原。如:

It is time that the government took/should take measures to proteet the race birds and animals.

3、for fear that主+should+v原。如:

He is working hard for fear that he should fall behind.

4、用在If only句型中,意思是“要是…就好了”。如: Look at the terrible situation I am in!

If only I had follwed your advice.

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

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)

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。

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.。

虚拟语气中的含蓄条件句常见用法总结

虚拟语气中的含蓄条件句常见用法先看一道高考题: ___ more attention ,the trees could have grown better . A.Given B.To give C.Giving D .Having given (答案是A ) 句中" ...the trees could have grown better" 是一个表达虚拟语气的句子。题中要求选择的是如何表达假设条件的形式。如果我们把这个句子用另一种形式"If they had been given more attentio n ,the trees could have grown better ." 来表示,就不难理解了。很多情况下,在表示假设的虚拟语气中,有时假设的条件并不以条件从句的形式表达,而是通过上下文或句中内在的逻辑关系,或用其它形式表达出来,我们称之为" 含蓄条件句" 。含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。这些表达形式在句中实际起着虚拟条件从句的作用。现分述如下:一、介词短语常用来表示虚拟条件的介词有with ,without ,in ,under ,but for 等等,它们表示的虚拟条件都可以被if 从句替换。 ( 1 ) without ,with without 表示否定的条件,意为if ...not ;with 与without 意义相反,表示肯定的条件。如: Without air , there would be no living things .(without air = if there were no air)没有空气,便没有生物。 With her help (= If I had her help ),I would do the experiment well .假如有她帮助,我就可以把这个实验做好。 ( 2 ) under Under the leadership of a less experienced person ,the experiment would have failed .( u nder ...= If there had been the leadership of a less experienced person )假设在一个缺 少经验的人领导下进行实验,实验准会失败。 (3 ) in I would have lost my head in that position .( in that position = if I had been in that po sition )我处在那种情况下,是会丧失理智的。 ( 4 ) but for

虚拟语气用法总结讲课稿

虚拟语气用法总结

虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达: a. 非真实的情景,不可能发生的事,即某种与事实相反或难以实现的情况,或说话人主观愿望。 b. 与客观事实相反地情景,即强制性虚拟语气,表示建议、命令、劝告这一类的意思上,表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的,其特点是主从句时态的不一致,而且一般有明显得标志。 二.虚拟语气的考点为: 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反:从句用一般过去时,主句的谓语用would (could, might) +动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反:从句用过去完成时,主句的谓语用would (could, might) +现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反:从句用should (were to,did) + 动词原形,主句的谓语用would (could, might) +动词原形 If it should/were to snow tomorrow, I would go skiing.

注意:虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略,再把were, should或had 移到从句句首,实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词,通常将if省略,主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间,这时主,从句谓语动词的虚拟语气形式因时间不同而不同,这叫做混合条件句。例如:条件句动作发生在过去,主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…,要是…多好”的语气表示与事实相反的情况,或表示将来不太可能实现的愿望。其宾语从句的动词形式为: He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形,其中should 经常被省略。这类动词包括: suggest, propose, recommend, demand, order, command, desire, require, insist,

虚拟语气用法归纳 虚拟语气主要指的的是带有非真实条件状语从句的复合句,表达的是说话人的遗憾后悔的语气,愿望以及建议,命令,要求等等的情感,往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后,有可能出现的情况。 虚拟语气的内容主要有三大模块,第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面:基本用法,各自为政,以及含蓄之美。 下表就是条件从句虚拟语气的基本用法: 通常,在上面表格里反映的是非真实条件句的虚拟语气模式,从句和主句的谓语动词时间是一致的,如果两者时间不一致,此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”,即从句和主句根据各自假设的时间不同,采用上面表格中对应的的谓语动词形式。 如何“各自为政”呢这就像是数学里的排列组合,一边有三种情况,交叉一搭配就出现了好多种情况。不管怎样,我们要遵循一个原则,就是“各自为政”。例如,从句是对过去情况的假设,而主句则是对现在情况的假设,那我们在使用时,从句就用过去完成式,而主句要用

would/could do的形式。当然,也不是所有的AB配就是合理的,有时候在具体语境下,会出现矛盾的情况,这时我们就要结合要表达的意思来 判断他们是对什么情况的假设,选择合适的形式。一般而言,主句的假 设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现 主句的现状。因此在此类的完成句子练习中,我们要特别提醒注意时间 状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设,主句是对现在的假设) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设,主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设,主句是对现在的假设) 5. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设,主句是对将来的假设) 6. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设,主句是对现在的假设) 7. If Jack hadn’t met Rose on his voyage, he would be alive now. (从句是对过去的假设,主句是对现在的假设)

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?

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

高中英语虚拟语气的用法

高中英语虚拟语气的用法 一、考查虚拟语气在条件从句中的用法 时间从句谓语形式(be用were不可改变)主句谓语形式 将来一般过去时(be用were) would/should/might/could+动词原形 现在一般过去时(be用were) would/should/might/could+动词原形 过去现在完成时would/should/might/could+had done (1)If he my advice, he wouldn' t have lost his job. A. followed B. should follow C. had followed D. would follow (2)If we the other road, we might have arrived here in time for the meeting. A. taken B. had taken C. took D. have taken (3) -John went to the hospital alone. -If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told 二、考查特殊句型中的虚拟语气 英语中需要使用虚拟语气的特殊句型不多,主理有以下类: 1.“倒装”类虚拟语气 当虚拟条件句中含有were, should, had时,有时可将引导虚拟条件句的连词if省略,而将从句中的were,should, had提到句首,构成倒装形式的虚拟语气。如: If he were here, she would agree too.→Were she here, she would agree too.如果她在这里,她也同意的。. If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match.假若明天下雨,我们只好推迟这场比赛。 If we had found him earlier we could have saved his life.→Had we 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。 注意,如果条件从句的谓语为否定式,其中的否定词not应置于主语之后,而不能与were,should, had等缩略成Weren' t, Shouldn' t, Hadn'场置于句首。如:我如不是警告了你,你就可能丧命了。 正: If I hadn' t warned you, you could have been killed. 正: Had I not warned you, you could have been killed. 误: Hadn' t I warned you, you could have been killed. 另外,有时省略if后提前到句首的had可能不是助动词,而是实义动词。 如: Had I time, I would go with you.假如我有时间,我就同你们一起去。句中的had不是构成过去完成时的助动词,而是表示“有”,如果不省略if ,完整形式为:If I had time, I would go with you. (1) Had I known about this computer program, a huge amount of time and energy____. (2010浙江卷) A.would have been saved B. had been saved C. will be saved D. was saved (2) fired, your health care and other benefits will not be immediately cut off. (2006湖北) A. Would you be B. Should you be C. Could you be D. Might you be 2.“宁愿”类虚拟语气 这里说的“宁愿”主要是指would rather。当它后接句子的时候,句子的谓语通常要用虚
