虚拟语气3

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

1.有时候假设的情况并不用条件从句表示出来，而是通过介词短语来表示。

如Without air(If there were no air), there would be no living things.

But for your help (If it hadn’t been for your help), I couldn’t have done it.

2. 假设的条件通过上下文表现出来。

I would go abroad for further study but that I am poor.

I was ill that day. Otherwise I would have taken part in the party.

3. 表示虚拟语气的主句或从句有时可以省略，但其含义仍可以推知。

（1）省去条件从句You could have washed your clothes yourself. （你本可以自己洗衣服的。）省去了If you had wanted to。（事实是：你自己没洗衣服，因为你不想洗。）

（2）省去主句（常用以表示愿望）If my grandmother were with me! (如果我的祖母和我在一起多好啊！)事实是：祖母已不在世。

虚拟语气详解(自用版)

虚拟语气详解（自用版） 虚拟语气是一项语法难点，为了让学员们便于理解与记忆，我们把虚拟语气分成三大块来讨论： 1．名词从句中的虚拟语气标志词+should+动词原形 2．条件从句中的虚拟语气①三种基本态②倒装虚拟句③混时虚拟句④含蓄虚拟句⑤跳层虚拟句 3．其它情形中的虚拟语气（wish/would rather/It’s high time…/If only…/lest） 一．三种基本形态（1） 表虚拟的时间if从句谓语形式主句谓语形式 现在：did / were would (should, might, could)+do 过去：had done/ had been would (should/might/could)+have done(been) 将来：were to/ should+do would (should, might, could)+do 三种基本形态（2）（这是基础，建议牢记下面的例句，争取能脱口而出） 与现在事实相反：If I had enough money, I would buy a book. 与过去事实相反：If I had had enough money, I would have bought a book. 与将来事实相反：If I were to have enough money, I would buy a book. If I should have enough money, I would buy a book. 二、倒装虚拟句（只能与过去/将来事实相反，省去if，只有三种倒装形式） Had I had enough money, I would have bought a book. Were I to have enough money, I would buy a book. Should I have enough money, I would buy a book. 三、混合时间虚拟语气（主要是抓住时间状语） (对过去事实虚拟+对现在事实虚拟) If I had studied English at school, I could read the English novel now. (对现在事实虚拟+对过去事实虚拟) If she were not so careless, she wouldn’t have made such a mistake. 四、含蓄虚拟句（在四级考试中目前还未出现此考点，但在阅读中常见） 3. 虚拟语气用在主语从句中。在句型“It is important (necessar y, strange, natural等) that...” 中，that 后面的从句中的谓语动词用(should) + 动词原形。 It's necessary that we should have a walk now. 我们现在有必要出去散散步。 What would I have done without you? But for their help, I would not have finished the task. But that the doctor arrived on time that day, they would have been dead.

(完整版)虚拟语气的用法及专项练习题[1]

虚拟语气的用法及专项练习题 虚拟语气表示一种假设的情况，或一种主观的愿望，即动词所表示的动 作或状态并非事实，或不可能实现。英语虚拟语气的形式有下列几种： 一.虚拟语气用于条件状语从句 注意:主句中的should 通常用于第一人称,would 可用于任何人称,同时 也可根据意思用情态动词could,might 等代替should,would 。 If I were you, I would give up drinking immediately. country. 3.与将来事实相反 If it were to/should rain tomorrow,the meeting would be put off. If you went there next time, you would see what I mean. 4.错综时间虚拟语气 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,动 词的形式要根据它所表示的时间来调整。例如: If I were you, I would have gone home.

If you had followed the doctor's advice,you would be quite all right now.(从句说的是过去,主句指的是现在。) If the weather had been more favorable ,the crops would be growing still better. 状语从句 1. 方式状语as if(as though) 如果从句表示与现在事实相反,谓语动词用一般过去时;表示与过去事实相反,谓语动词用"had+过去分词";表示与将来事实相反,谓语动词用"would(might,could)+动词原形"。例如: He looks at me as if I were mad. He spoke English so fluently as if he had studied English in England. 但as if(as though)后的从句也常用陈述语气,这是因为从句中的情况往往是可能发生的或可能被设想为真实的。例如: It looks as if our side is going to win. 2.目的状语in order that,so that 从句谓语动词用" may/might,can/could)+动词原形"。例如: She listened carefully in order that she might discover exactly what he wanted. 3. 连词引导的条件状语从句: in case , unless ,supposing ,providing,on condition that从句谓语动词用(should)或" might, could)+动词原形"。 4. 连词引导的步状语从句: lest ,for fear that等 We hid behind some bushes for fear that passer-by should see us. 二.虚拟语气用于宾语从句 注意：在此结构中that不可省略；should省不省均可。 He suggested that they (should ) stop smoking. They demanded that the black people should be treated as well as white people. 如果that 引导的从句所表达的内容是事实，也可用陈述语气。 He insists that he is right.

Wish and if only 引导的虚拟语气区别

if only强调所希望的状态并不存在，而wish则表示某事有可能发生。 一、wish用法说明 动词wish后接宾语从句时，从句谓语要用虚拟语气。 要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（be 动词一律用were）；表示与过去相反的愿望，从句谓语用过去完成时或 would/could+had +过去分词； 表示将来没有把握或不太可能实现的愿望，从句谓语用 would/could/should/might＋动词原形。 I wish I were not so busy.但愿我不那样忙碌。 I wish I were [was] better looking.要是我长得漂亮些就好了。 She wished she had stayed at home.她后悔的是她当时要是留在家里就好了。 I wish you would go with us tomorrow.要是你明天同我们一起去就好了。 I wish you wouldn’t look down on this kind of work.我希望你不要看不起这种工作。 This watch has gone wrong.

虚拟语气详解

虚拟语气详解 虚拟语气表示说话人的主观愿望（往往与客观事实相反），或是表示假象和猜测。虚拟语气无论从形式上还是时态上都比较复杂，需要归类记忆。 虚拟语气大体分为三类：(1) be型虚拟(2) were型虚拟(3) if 条件句及主句虚拟下面会详细说每种虚拟形式的特征和规律，考试时先判断属于哪种虚拟类型，剩下的皆是套路~ （1）be型虚拟（基本是套路） 形式：should + 动词原形，should可以省略 用法：1）表示“命令、建议、要求”等意义词语之后的宾语从句用be型虚拟，常见的词如下: demand, desire, insist, order, ask, command, propose, recommend, suggest, prefer, require, request等 最常见的形式是这类动词后面接着一个宾语从句，则宾语从句的谓语部分要用（should）+ 动词原形来虚拟 例: We demand that the meeting（should）be postponed. The manager suggested that we (should) work together. 注意：有时候你所见到不一定是上述动词引导的宾语从句，而是由上述词变体后所引导主语从句(it做形式主语，如：it is advised/ suggested/ requested/ ordered/ proposed that…)、表语从句或同位语从句 例如：It is required that the students (should) learn a foreign language. (主语从句) The requirement is that all the equipment in the meeting room (should) be checked twice before. (表语从句) We didn’t stand for his proposal that the meeting (should)be postponed. (同位语从句) 只要看到句中有上述动词或其变体，不管词性怎么变、句型怎么变，都用be型虚拟！ 特例：suggest和insist这两个比较特殊，当suggest作“暗示、表明、说明”讲，insist 作“坚持说”讲，后面一般跟的是客观事实，不需要虚拟~这是一个比较重要的考点，体会下面两组句子： We all suggest that a lab (should) be built. 我们都建议建一个实验室。 Her expression suggests that she is angry. 她的表情说明她生气了。 She insisted that we should find the source of the river. 她坚持主张我们应该找到河的源头。 She insisted that she had done nothing wrong. 她坚持说自己没做错事。 suggest 的区别很明显，但insist有点难辨别，一般来说如果insist后面跟的是某种主张，或是坚持要做一件事，那么用虚拟。 2）表示主观看法，常表示“某事是必要的、重要的。。。怎么怎么样的”，尤其是在“ it is +名词/形容词+ that从句”结构中，常见的形容词包括：advisable, desirable, essential, imperative, important, necessary, obligatory, proper, dispensable, impossible, natural, surprising等 例如：It is advisable that you (should) leave now. It is necessary that teenagers (should) take part in outside activities. It is of great importance that smoking (should) be banned in public area.

A．am B．was C．are D．were 【答案】D 【解析】试题分析：句意：我和我最好的朋友吵架了。我该怎么办？如果我是你，我就对她说对不起。虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。在虚拟条件语气句中，表示与现在事实相反的事实，条件从句中的谓语动词用过去式（be用were不用was），主句谓语动词为“would+原形动词”，所以选D。 考点：考查虚拟语气。 2．If I not so busy ,I with you . A．was , would go B．were , would go C．was , should go D．were , will go 【答案】B 【解析】句意“如果我不忙，我就跟你去”。本题考查对将来的虚拟语气。即“if+过去时，主语+should/would/could/might do”结构。故选B。 点睛： 3．If I ___ you, I ___ be afraid . A．was, wouldn’t B．were, won’t C．were, wouldn’t 【答案】C 【解析】 试题分析：根据语境可知此句的含义是如果我是你，我就不害怕。考查的是虚拟语气的基本用法。条件用过去时，主句要用过去将来时，故选C。 考点：虚拟语气 点评：虚拟语气其实就是if引导条件状语从句时，词义为“如果”，不过这个条件是无法实

复习专题虚拟语气专项练习题及答案 一、初中英语虚拟语气 1．–I argued with my best friend. What should I do? --If I ________ you, I would say sorry to her. A．am B．was C．are D．were 【答案】D 【解析】试题分析：句意：我和我最好的朋友吵架了。我该怎么办？如果我是你，我就对她说对不起。虚拟语气用来表示说话人的主观愿望或假想，所说的是一个条件，不一定是事实，或与事实相反。在虚拟条件语气句中，表示与现在事实相反的事实，条件从句中的谓语动词用过去式（be用were不用was），主句谓语动词为“would+原形动词”，所以选D。 考点：考查虚拟语气。 2．If I you, I give it to Microsoft research. A．am, will B．am, would C．were, would D．was, would 【答案】C 【解析】 【详解】 句意：如果我是你，我会把它交给微软研究部。 考查虚拟语气。根据If I you，这是一个虚拟语气，此句虚拟语气表示一种不能实现的假设，即与现在事实相反，谓语动词用过去式；该语法主要用于if条件状语从句，本句“如果我是你”，be动词用were，后面主句用过去将来时would＋动词原形，故答案选C。 3．I suggest that we Chinese people_______Chinese culture with love and joy everywhere we go. A．spread B．spreading C．to spread D．will spread 【答案】A 【解析】 【详解】 句意：我建议我们中国人无论走到哪里都要带着爱心和欢乐来传播中国文化， 考查动词suggest后跟虚拟语气。spread是动词原形；spreading是动名词；to spread是动词不定式；will spread是一般将来时。动词在这里suggest表示建议，后面宾语从句中使用虚拟语气should+动词原形，should可以省略。根据句意说明本句的suggest表示建议，故后面使用虚拟语气，省略了should，故选A。 【点睛】 动词suggest 后面可以跟名词作宾语，用于句型“suggest sth.”。如：I suggested a visit. 我提议参观。 suggest 后跟动名词作宾语，如：He suggested going home. 他提议回家。 suggest后面跟that引导的宾语从句时，用虚拟语气，一般省略情态动词should，所以本题选项是A。

(完整版)if引导的非真实性条件状语从句即虚拟语气

if 引导的非真实性条件状语从句即虚拟语气 通过动词形式的变化来表示说话人对发生的动作或存在的状态所持的态度或看法的动词形式称为语气。.英语中的语气分三种：陈述语气、祈使语气、虚拟语气。虚拟语气表示说话人所说的话不是事实，而是一种祝愿，建议，与事实相反的假设或实际可能性不大的情况等（即非真实的假设）。 If 引导的条件状语从句分为真实和非真实条件句（虚拟条件句）。真实条件句表示在假设的条件下，有可能实现的情况。非真实条件句表示的是假设的或实际可能性不大的情况，故采用虚拟语气。 If he does n’t hurry up, he will miss the bus.( 真实条件状语) If he was free, he asked me to tell stories.（真实条件状语） If I were you, I would go at once.（非真实条件状语从句） If there was no air, people would die.（非真实条件状语从句）1）非真实条件句中虚拟语气的基本形式。 假设类型条件从句的动词结果主句的动词 与现在事实相反动词过去式（be只用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/were to)+动词原形would/should/could/might + 动词原形

虚拟语气和错综条件时间从句区别

虚拟语气和错综条件时间从句区别 You would be much better now if you had taken my advice. （错综时间条件从句） You would have been much better now if you had taken my advice.(虚拟） 假若你当时听我的话，你现在就会好多了 在表示虚拟语气的句子中，条件从句表示的动作与主句表示的动作发生的时间并不一致，这时，谓语动词的形式要根据各自所表示的时间来调整，这种现象叫做错综时间虚拟语气。You would be much better now if you had taken my advice.假若你当时听我的话，现在就会好多了。（从句过去，主句现在）would have been 是与过去事实相反的非真实条件句 一般来说虚拟语气中的混合时态的句子都有具体的时间词来进行提示的，比如 说： If we had arrived at the shopping mall earlier, we would get more gifts now. 如果我们早点来商场的话（过去的时间虚拟），我们现在就可以拿更多的礼物了 （现在的虚拟）。 这是两个不同时间的虚拟语气，有相应的时间词来提示的，now来提示后句的时 间是现在而不是和前面一样的过去。 If we had arrived at the shopping mall earlier, we would have got more gifts. 如果我们早点来商场的话，我们就会拿到更多的礼物了。（已经拿了礼物了，但是实际上过去拿的时候没有拿到那么多） 如果从句和主句都表示过去的，那从句用had done,主句用 would ,could,might,should+have done 如：If you had taken my advice,you would not have been late for the meeting yesterday.如果从句表示过去的，但主句表示现在的，从句用had done,主句用would ,could,might,should+do,如：If you had taken my advice,you would not be late for the meeting now.这种一般都有个时间，如果没有表示时间的词也可以从上下文看出。 虚拟语气的用法错误。

虚拟语气用法归纳

虚拟语气（the subjunctive mood）用法归纳 第一部分：语气的定义和种类 1、语气(mood) 语气是动词的一种形式，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 ⑴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： ① There are two sides to every question. 每个问题都有两个方面。 ② Were you busy all day yesterday? 昨天一整天你都很忙吗？ ③ How good a teacher she is! 她是多好的一位老师啊！ ⑵祈使语气：表示说话人对对方的请求或命令。如： ① Never be late again! 再也不要迟到了。 ② Don’t forget to turn off the light. 别忘了关灯。 ⑶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： ① If I were a bird, I could fly in the air. 如果我是一只小鸟，我就能在空中飞行。 ② I wish I could pass the examination. 我希望我能通过考试。 ③ May you succeed! 祝您成功！ 第二部分：简单句中的虚拟语气 一、情态动词的过去式用于现在时态时，表示说话人的谦虚、客气、有礼貌、或委婉的语气， 常用于日常会话中。如： ⑴ Would you be kind enough to show me the way to the post office? 请你告诉我去邮局的路好吗？ ⑵ It would be better for you not to stay up too late. 你最好别熬夜到很晚。 二、表祝愿。 1、常用“may+动词原形”表示祝愿，但愿，may须置于句首（多用于正式文体中）。如： ⑴ May good luck be yours! 祝你好运！ ⑵ May you be happy! 祝你快乐！ ⑶ May you do even better! 祝你取得更大成就！ ⑷ May you have a good time. 祝愿你玩的痛快。 ⑸ May the friendship between us last long. 祝愿我们的友情天长地久。 ⑹ May you be happy. 祝你幸福。 【注意】本句型属于部分倒装句型，主语后用动词原形。 2、用动词原形。如： ⑴ Long live the people! 人民万岁！ ⑵ “God bless you,” said the priest. 牧师说：“愿上帝保佑你！” ⑶ Have a good journey! 祝愿你旅途愉快！ 三、表示强烈愿望。（该类型虚拟语气谓语仅用动词原形，第三人称单数也不加“s”） ⑴ God save me. ⑵ Heaven help us. 四、表命令。 1. 命令虚拟语气只能用在第二人称(you)，而且通常省略主语(也就是you)。 2. 句子尾通常加上感叹号。

Should型虚拟语气练习题

Should型虚拟语气练习题 1. 用于if引导的虚拟条件句中 在表示与现在或将来事实相反的非真实条件句中，谓语动词形式可用“should + do”。如：If she should refuse, they could be greatly disappointed. 【考例】This printer is of good quality. If it _______ break down within the first year, we would repair it at our expense. （2009年，天津） A. would B. should C. could D. might 2. 用于省略if的倒装句中 如果条件状语从句的谓语动词中含有should，可以省略连词if，而把should放在主语前构成倒装。如： Should he fail in the examination, he would have to wait for another year. 【考例】______ fired, your health care and other benefits will not be immediately cut off. (2006年，湖北) A. Would you be B. Should you be C. Could you be D. Might you be 3. 用于主语从句中 在“It is ＋形容词／某些动词的过去分词＋that从句”的结构中，从句的谓语动词用“（should）+ do ”虚拟语气形式来表示命令、要求和建议。这些形容词和过去分词常见的有important（重要的）、essential（必要的）、necessary（必须的）、natural（自然的）、decided（决定的）、ordered（命令的）、demanded（要求的）、proposed（建议的）、required （要求的）等。如： It is necessary that we (should) make everything ready ahead of time. 【考例】It is essential that all these figures ________ twice. (2008年，四川联考) A. check B. checked C. are checked D. be checked 4. 用于宾语从句中 表示主观判断、推测、建议、命令和要求的动词后的宾语从句中，谓语动词常采用“（should）+ do”的形式。这类动词包括advise（劝告），ask（要求），insist（坚持），order（下令），suggest（建议），command（命令），demand（要求），require（要求）等。 He insisted that a deadline (should) be set for completing the task. 【考例】The doctor recommended that you ______ swim after eating a large meal.（2009年，浙江） A. wouldn’t B. couldn’t C. needn’t D. shouldn’t 【疑难辨析】动词insist如不表示要求，而表示“坚持己见”时，宾语从句用陈述语气。同样，当suggest所表示的意思为“表明”或“暗示”时，谓语动词也不采用“should + do”的形式。如：Jane insisted that she had done nothing wrong and that she should be treated properly. The surprised look on his face suggested that he did not believe the fact.

(完整版)if引导的条件句中的虚拟语气

if引导的条件句中的虚拟语气 虚拟语气表示一种不能实现的假设。该语法主要用于if条件状语从句。 一、if引导的条件状语从句的分类及虚拟条件句的判断 1、可以把条件句分为两类： 1).真实条件句（Sentences of Real Condition）：凡是假设的情况发生性可能很大，就是真实条件句。例如： ⑴、If I have time , I will help you with this work.如果我有时间会帮助你做此工作的。 (2)、If time permits, we'll go fishing together.(如果有时间的话，我们就一起去钓鱼。） 2).虚拟条件句（Sentences of Unreal Condition）：当假设是不大可能实现时，就是虚拟条件句。例如： ⑴、If I were you , I would have attended the meeting. 如果我是你的话，就去参加会议了。 ⑵、If he had come here yesterday, he would have seen his ol d friend.假如他昨天来这儿的话，就会看见他的老朋友。 ⑴、If it had rained yesterday, we would have stayed at home.（如果昨天下雨的话，我们就会留在家里。） 2、.if条件状语从句中虚拟语气的判断 判断是真实条件句还是非真实条件句。只有在非真实条件句中才使用虚拟语气。通过句子意思，看假设的条件是否能够实现，能

够实现是真实条件句，不能使用虚拟语气；假设的条件不能实现则是非真实条件句，要用虚拟语气。 判断这个假设是与哪个事实相反。通常有三种情况：①与过去事实相反。②与现在事实相反。③与将来事实可能相反。 3、“后退一步法” 后退一步法是指在准确地判断了该句与哪一事实相反后，按虚拟语气的后退一步法处理从句谓语动词的时态。即：在非真实条件状语从句中，谓语动词按正常情况“后退一步”。也就是： ①与过去事实相反，在从句中用过去完成时形式表示。 ②与现在事实相反，在从句中用过去一般时形式表示。 ③与将来事实可能相反，在从句中用过去将来时形式表示。 主句中则用情态动词would, should, could 等加一个与从句一致的动词形式。例： ⑴、If I had come her yesterday, I would have seen him. ⑵、If I were a teacher, I would be strict with my students. ⑶、If it should snow tomorrow, they couldn't go out. 4、注意事项 ①if条件句中如有were, should, had，可以省去if，并使用倒装语序。 ②在现代英语中if条件状与从句中的谓语动词如果是be其过去形式一般用were。
