英语虚拟语气各种用法归纳课件

虚拟语气Subjunctive Mood

基本概念虚拟语气表示说话人的一种愿望、建议、命令、要求，有时是一种非真实的假设、料想或是不可能实现或与事实相反的愿望。

虚拟语气用法归纳一、If引导的非真实条件句（4）二、虚拟语气在其它状语从句中的运用（3）三、虚拟语气在名词性从句中的运用（3）四、虚拟语气在定语从句中的运用（1）五、特殊虚拟语气形式（4）一、虚拟语气在非真实条件句中的运用①主从句时态一致If he had time now，he wouldcould，might go

withyou.要是他现在有时间，他会和你一起去的。与现在事实相反If you had come a few minutes earlier，you would could，might have met the famous

singer.如果你能早来几分钟，你就会见到那个著名歌手。与过去事实相反If it were to snow this evening，they would not go

out.如果今天晚上下雪，他们就不会出去。将来发生的动作的可能性很小②、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。If you had asked him yesterday，you would knowwhat to do

now.如果你昨天问一问他的话，你就知道现在该做什么了。从句与过去事实相反，主句与现在事实相反。③、省略if的条件句虚拟条件句的从句部分如果含有were，s hould或had，可将if省略，再把were，should或had移到从句句首，实行倒装。Were they here now，they could help us.＝If they were here now，they could help

us.如果他们现在在这儿的话，他们就会帮助我们了。④、含蓄虚拟条件句含蓄条件句是指句中没有明显的虚拟条件句，而是利用其他手段来暗示存在虚拟条件。但是这类含蓄式虚拟条件句往往都可以转化为if引导的条件句。常用来表示含蓄虚拟条件的手段有：butfor要不是……的话，but

that要不是……，without如果没有……，supposing假设……，provided倘若……，ot herwiseor else要不然等。But for your advice，I would have failed.＝Ifyou hadn’t given me advice，I would have failed.如果不是有你的建议，我会失败的。But that she was afraid，she would have said no.要不是她害怕的话，她就会说“不”了。Without water，there would be no life.如果没有水，就没有生命。Supposing it should

rain，we would still

go.假如下雨的话，我们还是要去。二、虚拟语气在其它状语从句中的运用1由as

望虽然可能性我希望他明天能来。 might＋动词原极小，但有实现 She sincerely wished that she 形的可能 might do something to comfort

him.她真切希望能做点什么来安

慰他。2用于表示主观判断、建议、命令和要求等动词后的宾语从句中，常用“shou ld＋动词原形”表示虚拟语气，should常省略。常见的动词有：demand，desire，co mmand，order，require，insist，recommend，request，suggest，propose，advise，u rge规劝等。He suggested that we should start off early thenext

day.他建议我们第二天早点动身。3would

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

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。

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,

实用英语虚拟语气的解析及其用法讲解

实用英语虚拟语气的解析及其用法讲解在当前英语语法当中，有一些学生总结的几个难点语法，其中之一就是虚拟语气，怎样判断出句子使用了虚拟语气，是哪一种形式的虚拟语气是学生无法清楚掌握的难点。本文从虚拟语气的定义到各种形式都进行了详细的讲解和分析，并针对各种形式的用法都进行了分析和举例，讲解明白，以帮助学生们能更好地了解和掌握英语语法中这个难学的语言现象。标签：英语虚拟语气；定义；用法；分析及举例一、虚拟语气的定义（Subjunctive Mood）在我们了解什么是虚拟语气前，大家首先要弄清楚英语的语气表达，也就是英语学习中我们都会用到哪些语气。英语中的语气（Mood）可以分为：1The Indicative Mood（陈述语气）；2The Interrogative Mood（疑问语气）；3The Imperative Mood（祈使语气）；4The Subjunctive Mood（虚拟语气）4类。陈述、疑问、祈使语气在本文中就不再过多阐述。而我们在这里重点讲解虚拟语气。什么是虚拟语气呢？虚拟语气用来表示假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。虚拟语气表示说话者所说的话并非事实，或难以实现的，甚至表达相反的概念。另外表示主观愿望或表达某种强烈的感情时，也用虚拟语气。二、虚拟语气的判断及用法（一）if条件状语从句中虚拟语气的判断 if条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种：1与过去事实相反的假设。结构为：从句的谓语动词用“had+过去分词”，主句用“should（would，could，might）+have+过去分词”。 2与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should（would，could，might）+动词原形”。 3与将来事实相反的假设。结构为：从句的谓语动词用“should（wereto）+动词原形”，主句用“should（would，could，might）+动词原形”。（二）宾语从句中的虚拟语气 1wish后接宾语从句中的虚拟语气：根据从句的意义来判断 A：表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如：

(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

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 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.

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。

英语虚拟语气用法详解

英语虚拟语气用法详解 1. 英语语气的概念英语有三种语气，即陈述语气、祈使语气和虚拟语气。陈述语气用于陈述事实、提出看法或问题等，祈使语气用于表示请求、命令或警告等，虚拟语气则表示假想或主观愿望。如： I like this book the best. 我最喜欢这本书。(陈述语气) Don’t be so careless. 不要如此粗心大意。(祈使语气) I suggest that we should go tomorrow. 我建议我们明天走。(虚拟语气) If you dropped the glass, it would break. 假如你把玻璃杯掉在地上，它会打碎的。(虚拟语气) 3. 虚拟条件句的基本类型 (1) 与现在事实相反：若与现在事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If we left now, we should arrive in good time. 假如我们现在就走的话，我们就会及时到达。 (2) 与过去事实相反：若与过去事实相反，条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, coul d, might)+have+过去分词”。如： If he had been in that train then, he might have been k illed in that accident. 如果当时他也在那列火车上，他可能就死于那场车祸了。

(3) 与将来事实相反：若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如： If he went，would you go too? 如果他去，你也去吗?(大概他不会去) If I asked him，I’m sure he’d help us. 如果我向他提出要求，肯定他会帮助我们。(不过我不打算这样做) 3. 错综时间虚拟条件句所谓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，而主句即指的是现在或将来，此时应根据具体的语境情况，结合上面提到的三种基本类型对时态作相应的调整。如：If you’d listened to me, you wouldn’t be in such tro uble now. 如果你听了我的话，你现在也不会有这样的麻烦了。 If you were in better health, we’d have let you go wit h us. 你要是身体好一点，我们就让你和我们一道去了。 4. 含蓄虚拟条件句所谓含蓄虚拟条件句即指将条件从句隐藏在上下文一定的短语中的一类条件句。如： Anybody else would have believed you. 任何别人都会相信你的话了。 Without your help, I couldn’t have achieved all this. 要不是有你帮助，我不会取得这些成就。 I would have written before, but I have been ill. 我本想给你写信的，但我生病了。 5. if it weren’t (wasn’t) for与if it hadn’t been for

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? (=if you had a million dollars) 如果你有100万元，你会做什么？ We couldn?t have finished the work ahead of time without your help. (=if we

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

高中英语虚拟语气用法小结

虚拟语气用法小结白杨林河南省社旗县第二高级中学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，
