倒装句

为了强调或平衡句子结构,英语中常用倒装。倒装有全部倒装和部分倒装。

全部倒装是指将句子中的谓语动词全部置于主语之前。

部分倒装是指将谓语的一部分如助动词或情态动词置于主语之前。如果句中的谓语没有助动词或情态动词,则需添加助动词do,does或did等,并将其置于主语之前。

1.以here,there,now,then等地点或时间副词开头的句子,谓语动词是be, come, go, remain等,而主语又是名词时,用全部倒装。

注意:如果句子的主语是代词时,则不倒装。

如:Here comes the bus!/ Here it comes!

2.有些动词与副词out,in,up,down,away等构成不及物动词短语。为了使句子更生动,常将这些副词提前到句首,这时用全部倒装。

注意:句子的主语是代词时,则不倒装。

如:Up went the rocket. / Up it went.

3.将表示地点的介词短语放在句首进行强调时,使用全部倒装。谓语动词常为不及物动词。

如:From the window came the sound of music.

4.当句子主语部分较长,谓语部分较短,或为了强调句子的表语时,常使用全部倒装。句子的结构为“表语+系动词+主语”。

如:Gone are the days when we had nothing to eat.

5.if虚拟条件状语从句中,如果将连词if省略,需用部分倒装。

如:Were I you, I would go there.

6. as引导的让步状语从句的倒装有如下几种形式:

1) 从句的谓语部分为“不及物动词+副词”时,常将此副词提前到从句句首。如:Hard as you try, you will not be satisfied.

2) 从句的谓语部分为“情态动词+不及物动词”时,常将此动词提前到从句句首。如:Wait as you may, he will not see you.

3) 从句的谓语部分是“系动词+形容词”时,常将此表语形容词提前到从句句首。如:Proud as the nobles are, they are afraid to see me.

4) 从句的谓语部分是“系动词+单数名词”时,则常将这个表语提前,但要省略名词前的不定冠词。如:Child as he is, he can tell right from wrong.

7.具有(半)否定意义的词或短语位于句首时,用部分倒装。

如:seldom, rarely, not, never, by no means, in no time, hardly...when, no sooner...than, not only...but also等。

如:Not only does he do well in his lessons, but also he often helps others with their lessons.

Hardly did I notice the signal when I caught by police.

8.“only+状语”位于句首时, 用部分倒装。

如:Only then did I know the importance of English.

9.so...that结构中,有时要强调so所修饰的形容词或副词,常将so 连同它所修饰的形容词或副词一起提前放在句首。

如:So bright was the moon that the flowers seem as bright as by day.

10. 最突出、最常见的修辞效果就是强调,其表现形式如下:

1)only +状语或状语从句置于句首,被该状语修饰的句子用部分倒装。

Only in this way can you solve this problem.

只有用这种方法,你才可以解决这个问题。

Only after he had spoken out the word did he realize he had made a big mistake.

只有当他已经说出那个字后才意识到自己犯了个大错误。

2) hardly,in no way,little,scarcely,seldom,never,no more,no longer,not,not only,no sooner,not only …(but also),not until…等具有否定意义的词或词组位于句首,句子用部分倒装。

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)

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,

虚拟语气语法汇总

虚拟语气 在英语文法中有三种语气,即直述式语气(Indicative Mood)、祈使语气(Imperative Mood)和虚拟语气(Subjective Mood),其中前两种我们早已熟悉了,这里则不多谈了,如:How beautiful she is! 则是直述式语气,而Hurry up! Don't 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were Should/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 I could fly to the moon.

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.

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

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? (=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
