【答案】C
【解析】
试题分析：句意：--彼得打算参加劳拉的派对，但是他不知道穿什么。-- 如果我是他，我就戴一顶帽子。那会使他很酷。虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。其主要有三种结构：
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”
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, could, might）+have+过去分词”
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”。根据句意可知是于现在的情况相反，故选C
考点：考查虚拟语气的用法。

47．— What would you do if you _______ a million dollars?
— I would give it to charity.
A．have B．had C．will have D．would have

48．If I ___ you, I ___ be afraid .
A．was, wouldn’t B．were, won’t C．were, wouldn’t

高中英语语法虚拟语气 教学设计 集团档案编码：[YTTR-YTPT28-YTNTL98-UYTYNN08]
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。

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）

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．。

A．am B．is C．were D．was 【答案】C 【解析】 试题分析：if从句的虚拟语气，对于现在的虚拟用一般过去式，be动词都用were,故选C.句意：——我不知道聚会该穿什么。——如果我是你，我会穿一件衬衫加一条领带。故选C 考点：if条件句的虚拟语气 点评：if条件句的虚拟语气，是中考要求掌握的知识点，分为三种情况： 表示与现在事实相反的情况，从句谓语动词用一般过去式（be用were），主句谓语动词用should/would/could/might +do;2.表示与过去的事实相反的情况，从句谓语动词用过去完成时，主句谓语动词用should/would/could/might+have done;3.表将来的事实相反的情况，从句谓语动词用should+动词/did/were to do，主句谓语动词用should/would/could/might +do。 2．If I _______ you, I _______ go there. A．is; will B．is; would C．were; would D．was; will 【答案】C 【解析】本题考查虚拟语气，if引导的与现在事实相反的虚拟语气。从句用一般过去式，主句用过去将来时。句意：如果我是你的话，我会去那儿的。 1.57．---What would you do if you a million dollars? ---If I you, I’d give it to medical research. A．got, were B．win, am C．won, am D．get, were 【答案】A 【解析】本题是考查的虚拟语气，对于将来的假设，主句用过去将来时，从句用一般过去时，且be动词为were，故选A 2.58．What _____ you _____ if you had a million dollars? A．would, did B．will, do C．would, do D．will, did 【答案】C 【解析】本题是对于虚拟语气的特殊疑问句的考查，根据句子的结构，选C 3．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。
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】虚拟语气选择题练习 一、初中英语虚拟语气 1． ---Tom is always making so many mistakes in his English exercises! --- Yeah. If he ________ more careful, he ________ fewer mistakes. A．was; will make B．is; would make C．were; will make D．were; would make 【答案】D 【解析】 试题分析：句意：汤姆总是在英语练习中犯那么多的错误！—如果他能更细心一些，他就会犯更少的错误。 表示与现在事实相反的假设，If+主语+动词过去式（be动词用were），主语+would/should/might/could+动词原形。根据题意及句型，故选D。 考点：考查虚拟语气的用法。 2．The air pollution is worse and worse. The government suggests that people ____ to work by subway or by bus. A．go B．goes C．going D．to go 【答案】A 【解析】 【详解】 句意：空气污染越来越糟糕。政府建议人们乘地铁或者乘公交车去上班。 考查谓语动词。A. go 去；B. goes 去；C. going 在去；D. to go 为了去。这是一个that引导的宾语从句，suggest后跟的宾语从句应用虚拟语气（should）do结构，should可省略。故选A。 3．If I _____ you, I _____ late for school this morning. A．were, wouldn’t be B．were, wouldn’t C．was, won’t be D．am, will 【答案】A 【解析】 试题分析；句意：如果我是你，今天早晨我上学就不会迟到。与现在事实相反，故从句用过去时态，主语用过去将来时态。选项B缺少谓语动词。故选A。 考点：if引导的条件状语从句 点评：虚拟语气是一种特殊的动词形式，用来表示说话人所说的话并不是事实，而是一种假设、愿望、怀疑或推测。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，
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.
虚拟语气 一、语气（Mood）的定义和种类 l、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： （1）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： We don’t have dinner in that restaurant. What an adorable baby it is! （2）祈使语气: 表示说话人的建议、请求、邀请、命令等。如: Open the window, please. Take care of your suitcase. （3）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 well. May you succeed! 例如： If I were a boy even just for a day, I’d roll out of bed in the morning and throw on what I wanted. ——Beyince《If I were a boy》中文翻译只是需要表达意思，然而英文中，动词发生了变化，本来应该是am，现在为were，把时态往后面退了一步。I’d roll中，would roll，根据初中所学，if表示主将从现，would roll是will roll的时态的退后。可是为什么am的退后不是was而是were呢因为这是英语的习惯。 If he were (习惯)(is) telling the truth, he wouldn’t have told us. ——Pirates of the Caribbean Would have done 表示对过去的推测 If all the youths of America were as fortunate in securing an education as we have been, then the future of the United States would be more bright than it is today. ——DreamMakes Me Catch TheOpportunity [通过虚拟来突出重要性，例：如果没有电..]阅读中方便理解，写作中可以用此句型表示强调。 考法： 表示的是假的，如何时态退一步： 五大类： 一般现在时退为一般过去时，一般过去时退为过去完成时，现在进行时退为过去进行时 还有情态动词，如：must be 退为must have done 但我们还需记住一些标志词，如【表示假的】 If【最常见】as if/though【好像】wish、if only、would rather【宁愿、宁可】 例句：She is good at English, as if she were a American.[表示虚拟] should类的【傻的】 I drop caps. Insist desire/demand recommend/require order command advice p suggest 二、虚拟语气在条件从句中的用法 条件句有两类，一类是真实条件句，一类是虚拟条件句。如果假设的情况是有可能发生的，就是真实条件句。在这种真实条件句中的谓语用陈述语气。如: If it doesn’t rain tomorrow, we will climb the mountain. 如果明天不下雨，我们就去爬山。 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 told you about that. 如果他昨天见到你，他会告诉你那件事的。 在含有虚拟条件句的复合句中，主句和从句的谓语都要用虚拟语气。列表如下：
