高中英语虚拟语气详细讲解大全
高中英语虚拟语气详细讲解 虚拟语气 什么是虚拟语气？是的，我们要学习虚拟语气就必须先弄明白它的概念。 虚拟语气包含两种：一种指与事实相反或不可能发生。“虚拟条件句+虚拟主句”的结构都属于这一类；even if、even though、as if、as though引导的状语中如果需要用到虚拟语气也属于这一类；wish、would rather后面接的宾语从句表示不可能实现的愿望，还是属于这一类。 另一种指与事实实际是否发生没有直接关系。如和suggest、order、demand等表示建议、命令、要求等相关的名词性从句都属于这一类。 大家知道以上两类虚拟语气后，我们就从从句的角度来系统学习虚拟语气。紧跟小简老师的步伐哦！ 一. 虚拟条件句中的虚拟语气 1、表示与现在事实相反的情况 从句：If+主语+did(be动词用were) 主句：主语+ should/would/might/could+do
If I were you,I would take an umbrella. 如果我是你，我会带把伞。（事实：我不可能是你） If I knew his telephone number,I would tell you. 如果我知道他的，我就会告诉你。（事实：不知道） If there were no air or water,there would be no living things on the earth. 如果没有水和空气，地球上就不会有生物。(事实：地球上既有空气也有水) 2、表示与过去事实相反的情况 从句：If+主语+had+done 主句：主语+should/would/might/could+have done If I had got there earlier,I should/would have met her. 如果我早到那儿，我就会见到她。（事实：去晚了） If he had taken my advice,he would not have made such a mistake. 如果他听我的劝告的话，就不会犯这样的错误了。（事实：没有听我的话） 3、表示与将来事实相反的情况

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。
牛津高中英语模块六M6U4虚拟语气练习
M6U4虚拟语气讲解 2011.12.16 一、虚拟条件句 1．非真实条件句的形式，根据时间的不同可分为如下三种： ⑴表示与将来的事实或愿望相反 ①If it snowed / should snow / were to snow tomorrow, we would change our plan． 要是明天下雪的话，我们就改变计划。 ②If we changed / should change / were to change our plan, they would be disappointed． 如果我们改变计划，他们会失望的。 ⑵表示与现在的事实或愿望相反(be动词常用were) ①If I knew the answer, I would tell you．如果我知道答案，我会告诉你。 ②If 1 were rich，I would donate money to the Hope Project． 要是我富有的话，我会捐款给希望工程。 ⑶表示与过去的事实或愿望相反 If you had arrived ten minutes earlier, you could have danced with the American Indians． 如果你早十分钟来的话，你就可以和印第安人跳舞了。 2．可以省去条件句中的if，使用倒装句，即把从句中的should，were和had置于句首。 ①Should it snow tomorrow, we would put off our celebration． 如果明天下雪，我们就推迟庆祝会。 ②Were I rich, I would buy an expensive cal．要是我有钱，我就买一辆昂贵的汽车。 ③Had you attended the lecture, you could have known the special custom． 如果你听了讲座，你就会知道这种特殊的习俗了。 3．虚拟条件句中的谓语可用进行时，表示“如果……正在……”等含义，主句中的谓语仍用would（或might，should，could），并根据情况选用时态。如： ① If we weren’t living in the 21st century, people would treat the event in an old way. 要不是生活21世纪，人们会用旧有的方式对待这个事件。 ②If Mary were living a hard life, her parents should be responsible for it. 要是玛丽生活艰难的话，她的父母应该对此负责。 4．错综虚拟语气(也叫混合时间虚拟语气) 如果虚拟句的主、从句中动词表达不同的虚拟动作时间，则该句被称为“混合条件虚拟句”。句中动词采用何种形式（现在或过去虚拟式）要依据主、从句中的时间状语（或上下文）来确定。如： ①If you worked hard now, you would get a good job in the future． 如果你现在努力，将来会有好工作。 ②If he had not been caught in the rain yesterday, he wouldn’t be ill now． 要是他昨天不淋雨的话，现在就不会生病了。 ③If David had received six more votes in the last election, he would be our chairman now． 如果大卫在上次的选举中多赢得六张选票，那么他就会是我们的现任主席。 【注意】在混合条件虚拟句中，要注意事实和虚拟假设的混合。要根据所述事实发生的时间确定它的时态形式。 ①I would have gone to visit him in the hospital had it been at all possible，but I Was fully occupied the whole of last week．如有可能，我本来会到医院去看望他的，但整个上周我实在是太忙了。（说明过去情况，用一般过去时） ② If Tom didn’t work overtime today, he would come to our reception. However, he is preparing the coming exam now. 如果Tom今天不加班，他回来我们的宴会的。然而，他现在正准备即将到来的考试。（说明现在情况，用现在进行时） ③Should it not rain tomorrow, I might travel around our town. What a pity! I will have to help my father on the farm. 万一明天不下雨，我可能会周游我们镇。真遗憾，我不得不在农场上帮助我父亲。（说明将来情况，用一般将来时） 5．“could have + 过去分词”也可用于虚拟条件句中，这时的could是情态动词，表示“能够”，相当于：had been able to……。比如： ① If I could have earned enough money, I should have traveled over the world. 要是我挣的钱足够多的话，我就会周游世界了。 ② If you could have prevented mistakes, you might have been more successful. 如果你能避免错误的话，你会更加成功的。 6．Were it not for sth: （与现在或将来情况相反）要不是因为…… Had it not been for sth: (与过去情况相反) 要不是因为…… ① Were it not for the heavy traffic today, I would set off to my school. 要不是因为今天繁忙的交通，我就动身去学校了。 ② Had it not for the delay, they could have completed their long march yesterday. 要不是因为耽误，他们昨天就能结束他们的长征。 7．隐含条件虚拟句 虚拟句中没有明显的虚拟条件，而是利用其他手段来暗示所存在的虚拟条件(可转化为if 条件虚拟句)，此类虚拟句被称为“隐含条件虚拟句”。 ⑴由without，but for，with（要不是因为）等词引导的介词短语表示隐含条件。 ①I couldn’t have lived through Christmas without giving you a present．(=I couldn’t have lived through Christmas if I hadn’t given you a present.) 若不送给你礼物，我无法过这圣诞节。 ②But for your timely help，we couldn’t have finished the work on time. (=We couldn’t have finished the work on time if you hadn’t given us your timely help.) 要不是你们及时给予帮助，我们不可能按时完成工作。
英语虚拟语气语法归纳总结

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．。

虚拟语气的基本容 【开头引入】 If 如果(如果有两种可能,有可能发生的，不可能发生的。) ①有可能发生If it rains tomorrow, I will not go to the park. ②不可能发生虚拟语气，例如，如果我是明，。。。 虚拟语气表示说话人的愿望，假设，猜测或建议，而不表示客观存在的事实。所以，凡表示与事实不符的假设，想象，愿望时，需用虚拟语气表达。 一、If 引导的虚拟 （一）If 引导的虚拟语气,可用下表表示。 例如： ①与现在事实相反：If I had wings, I would fly over the sea. ②If she were rich, she would buy a bigger house. If there were no gravity, we would not be able to walk on the earth. ②与过去事实相反： If You had gone to the party, You would have seen YaoMing. If you had taken my advice, you would not have failed in the exam. ③与将来事实相反： If he were to tomorrow, We would have the meeting. If he should come tomorrow, We could go to the park together. If there were a heavy snow next Monday, we would not go skating. （二）if虚拟语气条件句的省略倒装。 如果虚拟条件从句中有were, had, should,可把if 省略，把were, had, should 提到主语前面，成为倒装结构。 ①If I were you, I would accept the challenges. ----Were I you, I would accept the challenges ②If you had informed me earlier, I wouldn’t have signed the contract. ----Had you informed me earlier, I wouldn’t have signed the contract. ③If she should be my daughter, I wouldn’t allow her to study abroad. ----Should she be my daughter, I wouldn’t allow her to study abroad.
高中英语语法之虚拟语气讲解
【The Subjunctive Mood】 语气 (mood)是一种动词形式，用以表示说话者的意图或态度。英语中的语气有三种：陈述语气、祈使语气和虚拟语气。 陈述语气(indicative mood),表示所说的话是事实。 祈使语气 (imperative mood),表示所说的话是请求或命令。 虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或及事实相反的假设等。 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及非真实条件句(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，句中的条件从句及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，句中的条件从句及结果主句皆须用虚拟语气。
1. 及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. 及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. 要是当初她被邀请的话，她就会去参加这次聚会了。 （事实是：当时没有人邀请她，因此，她没有来参加聚会。表示后悔。） If she hadn't called me, I would have overslept this morning. 今天早上，她要是不叫我的话，我就会睡过头了。 （事实是：她今天早上叫我了，我没有睡过头。表示感激。）
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.
高中英语虚拟语气详解精讲
高中虚拟语气精讲 英语动词有三种语气，陈述语气，祈使语气和虚拟语气。 定义：用来表示说的话不是事实，或者是不可能发生的情况，而是一种 愿望，建议，假设的语气叫虚拟语气。 ●虚拟语气在条件状语从句中的用法。 假如我有足够的钱, 我就去环游世界. If I had enough money, I would travel around the world. 假如我是你, 我就不会说那样的话. If I were you, I would not say that. 假如我听了你的建议, 我就不会犯错误了. If I had taken your advice, I wouldn’t have made a mistake. 假如明天下雪的话, 我就不去野营了. If it should rain tomorrow, I wouldn’t go camping. ●有时表示虚拟语气的条件从句或者主句都可以省略，而只剩下一个 主句或者一个条件从句。 ●假设条件从句谓语动词发生的时间与主句所假设的谓语动词不一致， 叫做错综条件虚拟语气。主句和从句的谓语动词要依照假设的时间 而定。(“各归各”的原则） If the weather had been finer, the crops would be growing still better. If you had followed the teacher’s advice, you wouldn’t fail the exam now. ●假设条件虚拟倒装。条件从句中有should，were，had三个助动 词可以把if省略，并将这三个词提至句首。 If I were you, I would give it up. Were I you, I would give it up. If it were not for your advice, we couldn’t have got over the difficulties. Were it not for your advice, we couldn’t have got over the difficulties. If I had had time, I would have run round that lake again. Had I had time, I would have run round that lake again. If there should be a flood, what should we do? Should there be a flood, what should we do? 没有阳光，人们的生活将于今天的截然不同。 Without sunlight, people’s life would be different from today. 要是没有你的帮助，我就不能完成那项工作。 But for your help, I wouldn’t have finished the work. With favorable winds, we might have arrived there in two days. ●with, or, otherwise, but, however 引导的从句如与事实不符，用虚拟 My parents lent me the money. Otherwise, I couldn't have afforded the trip.我父母借钱给我了。否则，我可付不起这次旅费。（虚拟） Shut the window, otherwise it'll get too cold in here. （非虚拟） I'm lucky that I'm interested in school work, otherwise I'd go mad.
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?

虚拟语气 一．一般虚拟条件句 (1) 与现在事实相反 ——If I were you, I wouldn’t worry. ——If I had the book at hand, I would read the passage to you. 那么，虚拟语气现在时的句型为： 从句：If + 主语＋动词过去式(be 变were) +… 主句：主语＋would (should ,could ,might ) + 动词原形＋… (2) 与过去事实相反 ——If you had gone to last night’s games, you would have met him. ——If the policeman had arrived earlier, he would have seen the accident. 那么，虚拟语气过去时的结构是： 从句：If＋主语＋过去完成时… 主句：主语＋should (或would,could,might) + 现在完成时… (3) 与将来事实相反 ——If he should come tomorrow, I would give him the dictionary he needs. ——If Mr. Li were to do the experiment tomorrow, he might read the instructions carefully.

考研英语语法虚拟语气解析(一)
考研英语语法虚拟语气解析（一） 虚拟语气是谓语动词的一种形式，用来表示假设，或用来表示命令、建议以及说话人的主 观愿望，有时也可以使语气缓和、委婉。虚拟语气作为一重点语法，在各类考试中占有相当 大的分值，所以理解该语法，不管对于考试，还是在日常应用中都有相当大的作用，本节将 就考试重点作详细讲解。 一、虚拟语气的用法 常用于条件句中，表示与现在、将来、过去相反的假设，表示与现在、将来、过去相反假设时，主句与从句谓语动词的变化形式，现以动词do为例说明。 主句从句现在would/should/could/might + do be 宀were/do 宀did 将来 would/should/could/might + do were to + do/should + do （只能用should）过去 would/should/could/have done had done注：有些语法书中在"与将来相反假设”的条件从句中也有do i did，这样就和“与现在相反假设”的主句、从句完全相似，其主要区别在于各自的时间状语上，另外如果在“与将来相反假设”的条件从句中出现should+ do，那么主句 中就避免使用should+do，可以用would/could/might+do。 例句：If you were to exam ine the birth certificates of every soccer player in 2006 s World Cup tour name nt, you would most likely find a no teworthy quirk. （选自2007 年Text 1） 分析：该句是复合句。 译文：假如你去调查2006年世界杯上每位足球运动员的出生证明，你很可能会发现一 个值得注意的现象。 例句：If that happe ned, passi on ate con sumers would try to persuade others to boycott products, putting the reputation of the target company at risk.（选自2011 年Text 3）分析：该句是复合句，表示与现在相反的假设。其中，分词短语putting the reputation of the target company at risk在句中作状语，表示结果。 译文：这种情况一旦发生，充满激情的消费者会尽力说服他人抵制产品，从而使目标企业的声誉处于危 险境地。 例句：Everything here would have been destroyed utterly , if his wife hadn t called the fire brigade. 分析：该句是复合句。 译文：要不是他的妻子给消防队打电话，这里的一切就被彻底地破坏了。 二、混合式虚拟语气 有时条件从句和主句时态不一致，可以根据主句、从句动作发生的时间分别运用相应的 虚拟语气。 例句：He would be studying at the university now if he had passed the entrance exam in ati on.
