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.

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)

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。

高中英语 第二册 语法总结 虚拟语气

新概念英语第二册语法总结:虚拟语气 虚拟语气分三种情况来掌握: 1、虚拟条件句。 2、名词性虚拟语气。 3、虚拟语气的其他用语。 一、虚拟条件句: 条件状语从句是非真实情况,在这种情况下要用虚拟语气。 1、条件从句与现在事实不一致,其句型为: If 主语+过去时,主语+should(could, would, 或might)+动词原形,如: If I were you, I would study hard. If it rained, I would not be here now. 2、条件从句与过去事实不一致,句型为: If 主语+had+过去分词,主语+should(could, would, 或might)+have+过去分词,如:If the doctor had come last night, the boy would have saved. If I had not studied hard, I would have failed in the exam last term. 3、条件从句与将来事实不一致,句型为: If 主语+should(were to, 过去时)+do,主语+should(could...)+原形do,如: If it should rain tomorrow, we would stay at home. If I were to go to the moon one day, I could see it with my own eyes. If you missed the film to night, you would feel sorry. 注意问题: 1、If条件句中绝对不可出现"would"。 2、根据句中的时间状语,有时可能出现“混合虚拟”的情况,即主句可能是现在的情况,条件句也许是发生在过去的情况,但都是遵守上述句型。 3、在条件句中如果出现were, had, should可省去if,将主语与这些词倒装,例如: Had the doctor come last night, the boy would have saved. Were I to go to the moon one day, I would see it with my own eyes. Should it rain tomorrow, we would stay at home.

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

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)

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.。

1语法辨析 In correct: If I was a girl, I would marry you Correct: If I were a girl, I would marry you 表示与现在事实相反的虚拟语气时,if条件句中的be动词一律用were,这句话应译为我要是个女孩,我就嫁给你。实际上不可能是个女孩。 In correct: If I were you I will not worry Correct: If I were you I should n't worry 现在时的虚拟语气主句要用should或would加动词原形,这句话应译为我要是你的话,就没有必要烦恼。要注意这种语态用在这里实际上是想把要讲出的观点表达得婉转些,有礼貌些。 In correct: God forgives you! Correct: God forgive you! 这里的主语God是第三人称单数,之所以动词不加s是因为要表达一种祝愿,即人力所不能及的事情,实际上是forgive前有一助动词should, May 等, 但在口语中将其省略了。如:May you be happy祝你幸福。 In correct: If the weather was nice yesterday, we would have gone to the zoo Correct: If the weather had been nice yesterday we would have gone to the zoo

(完整)虚拟语气用法归纳,推荐文档

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) 8. If Lily didn’t attend today’s party, she could not have the chance to work in the company next week. (从句是对现在的假设,主句是对将来的假设) 9. Had Father followed my travel plan , our family would not stay at home now. (从句是对

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,

语 法 讲 解 ——虚拟语气

语法讲解 ——虚拟语气 英语中有三种不同的语气:陈述语气,祈使语气和虚拟语气。虚拟语气表示动作或状态与事实相反,或不可能发生的情况。 1. 表示与现在事实相反或不可能发生:条件状语从句:一般过去时(虚拟语气中be→were)主句用:would(should, could, might)+动词原形。 If we had time now, we would read it again. If I were you, I would work hard. 2. 表示与过去事实相反或不可能发生:条件状语从句:had+过去分词;主句:would(should, could, might)+have+过去分词。If he had taken my advice, he would have succeeded in the test. If I had known your telephone number then, I would have called you. 3. 表示与将来的事实可能相反或不可能发生:条件状语从句: ①一般过去时②should +动词原形③were to+动词原形;主句:would(should, could, might)+动词原形。 If it should rain, the crops would be saved. If it were to snow tomorrow, they would not go out. P.S 虚拟条件句的特殊情况

(1). 混合/错综型虚拟语气 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,称为‘错综条件句’,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.(从句说的是过去,主句是现在) If I were you, I would have taken his advice.(从句是现在,主句是过去) (2)省略if的虚拟语气 如果从句中含有were/ should/ had时,则可以把这三个词置于句首,省略if.采用倒装语序。 If it should happen, what would you do? →Should it happen, what would you do? If he had recognized me, he would have come over. →Had he recognized me, he would have come over. (3) 含蓄虚拟条件句 有时候假设的情况不以if引导的条件从句形式表现出来,而是通过一个介词短语,连词或其他形式表示。常用的词或短语有:without, with, but for(要是没有), otherwise, or, but等。Without your help(=If we had not had your help), we could not have succeeded.

Dont 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 wereShould/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

虚拟语气语法讲解

虚拟语气语法讲解 虚拟语气 英语句子中谓语动词的语气有三种: 1. 直陈语气(The Indiative d)直陈语气用于直截了当地陈述事实、描述状态: He has published quite a nuber f essays this year .他今年已发表了好几篇论。 2. 祈使语气(The Iperative d) 祈使语气用于提出请求、命令、建议或是劝告等: ait utside until yu are asked . 请在外面等候,请你进再进去。 Lets ust take a break, shall we ? 我们休息一会儿,好吗? 3. 虚拟语气(The Subuntive d) 虚拟语气用于表示主观愿望和假设的虚拟情况。虚拟语气不太顾及事实的存在,它表现出说话人的主观因素比较多。所以说话人所讲的内容往往是与事实相反的;或是其实现的可能性微乎其微,甚至于没有实现的可能性。当然,有时为了使说话的语气客气、缓和、委婉,也使用虚拟语气。例如: I wish yu were re areful .但愿你更细心一些。 If I had re ney, I wuld buy a bigger apartent.

我要是有再多一点钱,我就买一套更大一些房子。 uld yu ind shutting the dr ? 劳驾您把门关上。 一、虚拟语气在条件状语从句中的构成和用法 1. 表示一种与过去事实相反的假设情况,条件从句中的谓语动词要用“had+过去分词”,主句中的谓语动词要用“wuld / shuld / uld / ight+have+过去分词”。如: If yu had e here yesterday, yu wuld have seen hi. 如果你昨天到这里,你就会看见他了。 2. 表示一种与目前事实相反的假设情况,条件状语从句中的谓语动词要用一般过去式(be动词常用were),而主句中的谓语动词则要用“wuld / shuld / uld / ight+动词原形”。如: If I had his telephne nuber, I wuld all hi nw. 如果我有他的电话号码,我现在就打电话给他。 If I were yu, I wuld nt tell hi that. 如果我是你,我就不把那件事告诉他。 3. 表示与将的事实可能相反的假设情况时,条件状语从句中的谓语动词要用:1) shuld+动词原形,或2) 一般过去式,或3) were+不定式,主句中的谓语动词要用“wuld+动词原形“。如: If it snwed trrw, any rps wuld die f ld. = If it were t snw trrw, any rps wuld die f ld. = If it shuld snw trrw, any rps wuld die f ld. 如果明天下雪,许多庄稼都会冻死。 4. 有时候,条件和结果不是指同一个时间,这时,应根据上面谈到的几种情况,使用相应的形式,这种虚拟语气
