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。
虚拟语气和倒装
Subjunctive mood (1) Nevertheless, should a fight follow, neither creature will be badly hurt, for the loser will save himself by making a gesture of submission. (Line 5) (2) If it had not had this disability it would have undoubtedly stayed in the jungle and hunted for food in the customary way. (Line12) If the human population had not increased so rapidly, people would have had more space and freedom. (Line 23) (3) If the caged lion, for example, were free to wander on the grassy plains of Africa, it would be continually active, ranging over long distances, hunting in family groups. (Line 15) 此三类句子体现了虚拟语气的三种时态变化。 （1）第1句中“should a fight follow”是表示将来情况的虚拟语气，意思为“if a fight should follow”，句中省略了“if”，将“should”提前，构成倒装，表示“万一，一旦”的意思。值得注意的是本句中的主句部分未使用虚拟语气。 (2) 第二部分这两句是与过去事实相反的虚拟语气。这类句子，从句用“had +动词过去分词”，主句用“would/should/could/might + have + 动词过去分词”。 (3) 第3句是与现在事实相反的虚拟语气。从句用“did/were”，主句用“would/should/could/ might + 动词原型”。 虚拟语气专项复习： A．虚拟语气在非真实条件状语从句中的用法 1、表示与现在事实相反的情况： if+主语+过去时+其他+主语+should/would/could/might+do+其他 例：If I were you, I would take an umbrella.如果我是你，我会带把伞。 If I knew his telephone number, I would tell you. 如果我知道他的电话号码，我就会告诉你。 If there were no air or water, there would be no living things on the earth. If I had any money with me, I could lend you some. 如果我带钱了，我就会借给你些。（事实：没带钱）If he studied harder, he might pass the exam.如果他再努力些，就能通过考试了。（事实：学习不用功）2、表示与过去事实相反的情况 if+主语+had done +其他+主语+should/would/could/might+have done+其他 例：If I had got there earlier, I should/could have met her. 如果我早到那儿，我就会见到她。 If he had taken my advice, he would not have made such a mistake. 3、表示对将来情况的主观推测 ①if+主语+did/should/were to do+sth.+主语+should/would/could/might+do+其他 ② if+主语+did/be(were)+sth.+主语+should/would/could/might+do+其他 ③if+主语+should+do+sth.+主语+should/would/could/might+do+其他 例：If he should come here tomorrow, I should/would talk to him. 如果他哪天来这儿的话，我就跟他谈谈。 If there were a heavy snow next Sunday, we would not go skating. If she were to be there next Monday, I would tell her about the matter. 4、有时，虚拟条件句中，结果主句和条件从句的谓语动作不是同时发生时， 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，我现在也会成为一个工程师了
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）

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．。

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.
大学英语语法-虚拟语气
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.
虚拟语气的用法及专项练习题
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。 1.与现在事实相反 (1) If had the time, John would make a trip to China to see the Great Wall. (2) If I were you, I would give up drinking immediately. 2.与过去事实相反 If I’d known that it was going to rain, I would never have gone for a walk in the country. 3.与将来事实相反
If it were to/should rain tomorrow,the meeting would be putoff. 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: (1) He looks at me as if I were mad. (2) 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 , lest ,for fear that等 从句谓语动词用" may/might,can/could)+动词原形"。例如: (1) She listened carefully in order that she might discover exactly what he wanted. (2) We hid behind some bushes for fear that passer-by should see us. 3. 连词引导的条件状语从句:

语法系列复习专题十-----虚拟语气、倒装句型 虚拟语气 虚拟语气是通过特殊的谓语动词形式来表达的愿望、假设、怀疑、猜测或建议等语气，它不表示客观存在。 一、虚拟语气在单句中的用法 常用来表示祝愿、采用固定的倒装句式。例如： Long live the People s Republic of China!中华人民共和国万岁！ be happy! 快乐！ have a good time! 玩得愉快！ May you 祝你 succeed! 成功！ make progress! 进步！ 二、虚拟语气在复合句中的用法： 1．在非真实性条件句和主句中的用法 条件从句主句 一般过去时（be多用于were）would/should/could/might＋动词原形 如果我是你，我会接受邀请的。 If I had time,I would go there. 如果我有空，我就去那儿。 条件从句主句 过去完成时would/should/could/might＋have done 如果你早点来，你就不会错过那辆公共汽车了。 If he had seen you yesterday,he would have returned your book. 如果他昨天见到了你，他就会还你的书的。 条件从句主句 一般过去时（be多用were） would/should/could/might＋动词原形 should do,were to do put off.万一明天下雨，运动会就推迟。（事实上明天下雨的可能性不大。） If you dropped/should drop/were to drop the glass,it would break. 万一杯子掉下来会打碎的。 4）i f的省略 如果条件句中有were,had,should 等助动词，可将if省略，而把were,had或should 置于句首,来表达以if引导的条件句的相同意思。 例如：Should it rain/were it to rain tomorrow,the sports meet would be put off./Had he seen you yesterday,he would have returned your book. 5)条件句或主句的省略 当有上下文或上下句中的语言环境暗示的时候，表示虚拟语气的从句或主句往往可以省略，以避免重复。 例如：——Why didn t you attend the party yesterday? ——I would/should have,but I was too busy then. I was surprised that you didn t like this job.You could have done it better.（后面省略了if you had liked it.） 6)混合时间条件句和主句 条件句和主句的动作发生的时间有先后之差，应按各自动作时间搭配好相应的结构形式。 例如：If the teacher hadn t been ill yesterday,who could give us a lecture now?/If you had
