2020考研英语暑期语法复习：虚拟语气表假设.doc
2020考研英语暑期语法复习：虚拟语气表假设同学们，是否在考研复习时,为英语语法而头疼呢? 不用担心。下面是我为大家带来的“虚拟语气表假设”相关内容，欢迎大家阅读。
虚拟语气表假设
本文讲解考研英语语法之【虚拟语气表假设】。语法是英语学习的基础，语法大关不过，阅读、完型、翻译和写作都会有难度，就别提过线和拿高分了。所以说，基础阶段，语法基础要打好。
状语从句相当于汉语的“假如…” “要是…”等。
请看一个句子：
If she invites me tomorrow, I shall go to the party. 如果她明天邀请我参加聚会，我就去。
这是个带条件从句的主从复合句，是直接的陈述语气，主句谓语动词用将来时，从句谓语动词用现在时代替将来时，表示能实现的动作。这句话说明说话人认为邀请的可能性较大。此句的条件是“只要她邀请我”，“去”这一动作就能实现。
请把这句话与下面虚拟语气的带条件从句的主从复合句进行比较：
1) If she invited me, I should go to the party. 假如她邀请我参加聚会，我就去。(说话人认为邀请的可能性较小或不可能。) 这句话主句谓语动词用过去将来时，从句谓语动词用一般过去时，其含义是：
She will probably not invite me, so I shall not go to the party. 她很可能不会邀请我参加聚会，所以我不会去。
2) If she had invited me yesterday, I should have gone to the party. 假如她昨天邀请我参加聚会，我就去了。
这句话主句谓语动词用“should + have + 过去分词”形式，从句用过去完成时，对过去发生的事情进行虚拟假设，表示与过去事实相反的情况，其含义是：
She didn’t invite me yesterday, so I didn’t go to the party. 她昨天没有邀请我参加聚会，因此我没有去。
3) If she should invite me tomorrow, I should go to the party. 如果她明天邀请我参加聚会，我会去的。
这句话主句谓语动词用过去将来时，从句谓语动词也用过去将来时，表示的意思是，“邀请我”的可能性较小，对将来要发生的情况表示怀疑。其含义是：
It is unlikely that she will invite me tomorrow, so I shall not go to the party. 明天她不可能会邀请我，因此我不会去。
从以上例句可以看出：虚拟语气的条件句是用谓语动词的特殊形式来表示与现在、过去事实相反的情况或对将来发生的情况表示怀疑，和直陈语气条件句的谓语动词形式以及所表达的含义完全不同。虚拟语气条件句中所用的谓语动词过去式、过去完成式、过去将来式等只表示不同的虚拟语气，与直陈语气句子的过去时、过去完成时等毫无关系，在学习时应注意加以区别，不要混淆。

高中英语语法虚拟语气教学：The subjunctive mood 厦门第十中学吕瑞珠 一、概述 本节课是高中英语语法教学课，授课内容为虚拟语气，授课对象是高三年学生。从呈现、加深记忆、巩固到实践并将语言项目运用于写作中并做适当的点评，大概需要两课时。但我这里着重阐述的是第一课时的教学内容、教学策略等。 通过本节语法教学课的学习，学生重新整合自己的有关虚拟语气的知识，复习已知的虚拟语气的表达形式如：I wish I could fly freely in the sky like a bird; It is high that you got up.等等，并学习新的表达形式如：The English teacher suggested that we should read the English newspaper every day; I would have passed the English exam if I had worker harder in the past 20 days.最为重要的是，学生在学习完虚拟语气的表达形式后，要在写作中运用。 虚拟语气在高中英语语法的难点之一，多数学生感到费解，因此也更需要老师的指导与相应的实践与运用，并且较好地掌握虚拟语气的表达形式，有助于扫除学生阅读过程中对个别句子的理解。 二、教学目标分析 1．知识与技能 1）复习学生已掌握的虚拟语气表达的句型： I wish I were… / I could … It is high time that you did your homework.. If I were you, I would… 2) 学习虚拟语气新的表达方式，尤其是if引导的虚拟条件状语从句，掌握与现在事实、与过去事实、与将来事实相反的三种虚拟语气的表达，特别是主句与从句时态的呈现；还有引导出的宾语从句需要运用虚拟语气的动词，如suggest, insist, propose, demand and so on. 3）培养学生运用所学知识表达自己的思想的能力。 2．过程与方法 1）引导学生在欣赏英文歌曲An Angel的情景教学过程中，开启对虚拟语气表达已有的知识记忆。
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．。
考研英语语法大全———自己总结
考研英语十二大基础语法体系 对于任何英语句子，要分析其结构，这样才能找到英语语言的规律。每种语言都有它的难点，汉语的难点在于汉语不是拼读语言，汉字很难写，而且有四种声调。其实，许多接触过多种外语的人都认为，英语的语法比法语、德语、俄语、日语等都简单，是最容易学的。著名语言学家乔姆斯基说过，语法是内生的、也就是随着语言的诞生而诞生的。因此，学习语法和学习语言是相辅相成的。 一、英语动词的时态 （一）英汉两种语言在时态表达方式上的差异： 英语的词类与汉语的不同。汉语词类形态稳定，比如“书”这个字，“一本书”、“三本书”都一样，没有词形变化。英语就不同了，book, books仅从词形上就能知道是单数还是复数。 动词是英语中变化最多、最复杂的词类。有人说，学好英语就是学好动词，此言甚是。同一个动作或状态分别在不同时间发生或存在，表达这个动作或状态的动词就要用不同的形式，这就是时态。 （二）英语动词的形式： 英语的时态是通过动词的变化来体现的。因此，了解动词的形式及其变化规律非常重要。英语的实义动词有以下五种形式： (1)动词原形：动词原形在句子中形式不变。主要用于主语为非第三人称单数的一般现在时，情态动词之后， 或根据语法规定必须用动词原形的其他情况。 (2) 一般现在时第三人称单数形式（简称现单三）：主要用于主语为第三人称单数的一般现在时。 (3) 过去式：主要用于一般过去时。 (4) 现在分词：主要用于进行时态，或语法规定的其他情况。 (5) 过去分词：主要用于完成时态，或语法规定的其他情况。 动词一般现在时第三人称单数（现单三）的构成，见下表：
即某些字母组合的不规则动词有一定的规律。如：weep→wept, sleep→slept, sweep→swept 以上每个时间段中分别有四种状态：一般、进行、完成和完成进行。因此我们便有了四四一十六个时态。 态（一般、进行、完成、完成进行）。 比如在“They are doing their exercises.”这个句子中，动词由原形do 变成are doing 的形态，说明这个事情是发生在现在、并处于正在进行的状态当中，所以叫现在进行时； 在“They have done their exercises.”这句中，动词由原形do 变成have done的形态，说明这个事情是发生在现在、并处于完成的状态，所以叫现在完成时； 在“They always do their exercises.”中，动词用原形do 的形态，说明这个事情是发生在现在、并且是一般情况下永远如此，所以叫一般现在时。 在这三句话中，动词do 虽然用了不同的形态，其意义没有变化，而是事情发生的时间和状态变了。其余类推。 （三）时态详解 16个时态中，常用的有12个：一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、将来进行时、现在完成时、过去完成时、将来完成时、现在完成进行时和过去完成进行时。其他时态很少单独使用。 下面把各种时态的构成和用法做一个全面的介绍。

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)
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）

初中英语语法三大从句总结
初中英语语法三大从句总结 在初中英语中，主要有三大从句，即宾语从句、定语从句、状语从句（包括时间、条件、结果、目的、原因、让步、地点、方式等）。 宾语从句 一、定义:在句子中起宾语作用的从句叫做宾语从句。 二、连接词 that: I think that you can pass the exam. Whether/if: I don’t know what the word means. “Wh”: I don’t know what the word means. I don’t know where he found the book. 只用whether的情况： 1. 与or not连用： I don’t know whether it’s raining or not. 2. 与动词不定式连用： He doesn’t know whether to accept the invitation. 3. 连接词前有介词时： It depends on whether he is coming. 三、时态 1. 主句是一般现在时态，从句根据实际情况而定(各种时态均可) She wants to know what he has done for the exam. 2.主句是一般过去时态，从句用相应的过去的时态。 1）She said that she was a student. 2）She said that she would fly to Japan in a week. 3）She said that she had finished her homework already. 3. 如果宾语从句说的是客观真理、自然现象或事实时，这时宾语从句要用一般现在时态。The teacher said that the earth goes round the sun. 定语从句 一、定义:在复合句中修饰名词、代词的从句叫定语从句。 二、先行词 先行词指人who /that 先行词指物which/ that 定语从句一般紧跟被修饰的名词或代词（即先行词）后
(完整)高中英语语法虚拟语气讲解
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.

虚拟语气 1. I wish (that可省略,下同)I knew the answer to the question.我希望知道这个答案。(事实上是不知道) 2. He wishes he hadn't lost the chance. 他真希望没有失去机会。(其实已失去) 3. You wished she would arrive the next day.(would + arrive) 你希望她第二天会到。(事实上她还没到) Subjunctive Mood作为专门表达假设意义和其他非事实意义的动词形式，仅是古英语遗留下来的残余。它仅有两个形式，即be型虚拟式和were型虚拟式。 Be型虚拟]----- be型虚拟式是以动词原形表示的，不管主语是什么人称，动词一律用原形，如动词为被动态，则助动词be也用原形。其主要用法如下： 1)用于表命令、决定、建议、坚持等词语之后的that分句中 这一用法又分三种情况： a)用在 decide,decree,demand,insist,move,order,prefer,propose,recommend,request,require, suggest,vote等动词之后的that分句中.（宾语从句） 在expect, believe, think, suspect等动词的否定或疑问形式后的宾语从句中，我们经常用“should＋动词原形(或完成形式)”，表示惊奇，怀疑，不满等。 He ordered that all the books be sent at once. He ordered that all the books be sent at once. we propose that somebody neutral take the chair. She insisted that she go to the south for her holiday. b)用在 advisable,appropriate,desirable,essential,fitting,imperative,important,impossible,nece ssary,obligatory,proper等形容词之后的that分句中。（主语从句） It is essential that all the facts be examined first. It was appropriate that thisi tax be abolished. I thousht it advisable that an armed guard stand in readiness. c)用在 decision,decree,demand,instruction,order,requirement,resolution等名词之后的that分句中。 The board has given instructions that the agent fly to Boston. We were faced with the demand that this tax be abolished. Their decision was that the school remain closed. 在这一用法中be型虚拟式能与“should+不定式”交替使用，也能与to-不定式交替使用。 He ordered that the books be sent at once . = He ordered that the books should be sent at onc. = He ordered that the books to be sent at once. 2）用于由if,though等引导的分句中.
