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

虚拟语气知识点总结和练习

虚拟语气语法总结虚拟语气主要指的的是带有非真实条件状语从句的复合句，表达的是说话人的遗憾后悔的语气，愿望以及建议，命令，要求等等的情感，往往说的是与事实相反或者没办法实现改变的东西。虚拟语气主要表现为在对过去现在或者将来的情况做出假设后，有可能出现的情况。虚拟语气的内容主要有三大模块 1.虚拟条件句第一模块就是涉及到条件从句部分的内容。这一部分的虚拟语气主要体现在三个方面：基本用法，各自为政，以及含蓄之美。下表就是条件从句虚拟语气的基本用法：通常，在上面表格里反映的是非真实条件句的虚拟语气模式，从句和主句的谓语动词时间是一致的，如果两者时间不一致，此时就是混合型虚拟语气。混合型虚拟语气的使用要求“各自为政”，即从句和主句根据各自假设的时间不同，采用上面表格中对应的的谓语动词形式。如何“各自为政”呢？这就像是数学里的排列组合，一边有三种情况，交叉一搭配就出现了好多种情况。不管怎样，我们要遵循一个原则，就是“各自为政”。例如，从句是对过去情况的假设，而主句则是对现在情况的假设，那我们在使用时，从句就用过去完成式，而主句要用would/could do的形式。当然，也不是所有的AB配就是合理的，有时候在具体语境下，会出现矛盾的情况，这时我们就要结合要表达的意思来判断他们是对什么情况的假设，选择合适的形式。一般而言，主句的假设时间会发生在从句的假设时间之后。因为是有这么一个条件才会出现主句的现状。因此在此类的完成句子练习中，我们要特别提醒注意时间状语的暗示 1. If I had seen you, I would not be so worried now. (从句是对过去的假设，主句是对现在的假设)

二、虚拟语气的判断： 1. if 条件状语从句中虚拟语气的判断。if 条件状语从句有真实条件句和非真实条件句。假设条件可以实现的句子为真实条件句，反之为非真实条件句，要用虚拟语气。其形式分为以下三种： (1) 与过去事实相反的假设。结构为：从句的谓语动词用“had + 过去分词”，主句用“should (would, could, might) + have + 过去分词”。例如： If it had not rained so hard yesterday, we could have played tennis. 如果昨天没有下大雨，我们就能玩网球了。 (2) 与现在事实相反的假设。结构为：从句的谓语动词用过去式，系动词用were，主句的谓语用“should (would, could, might) + 动词原形”。例如： If I were in your position, I would marry her. 如果我是你，我就娶她为妻。 (3) 与将来事实相反的假设。结构为：从句的谓语动词用“should (were to) + 动词原形”，主句用“should (would, could, might) + 动词原形”。例如： If you should miss the chance, you would feel sorry for it. 如果你错过了这次机会，你会难过的。 2. 宾语从句中的虚拟语气。 (1) wish后接宾语从句中的虚拟语气：根据从句的意义来判断。 A: 表示与现在和将来事实相反的愿望，从句谓语动词用过去时态。例如： I wish they were not so late. 要是他们来得不是这么晚就好了。 B: 表示与过去事实相反的愿望，从句谓语动词用过去完成时态。例如： I wished he hadn't done that. 我真希望那件事不是他做的。 (2) 表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气。用于此结构的动词有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest 等。从句的谓语动词用“should + 动词原形”，其中should 可以省去。例如： I insisted that he (should) go with us. 我坚持让他和我们一起去。注意：当insist 表示“坚持认为”、suggest表示“表明，显示”时，不用虚拟语气。例如：

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。）

关于虚拟语气的知识点整理

关于虚拟语气的知识点整理虚拟语气的重点是： 1．一些常见的虚拟语气的句型或结构。 2．虚拟语气的特殊形式，即用来表示要求、建议、命令、提议、意愿等的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式。 3．主从句表示不同的时间概念、事实或假设情况，从而交错成为复合虚拟语气。 4．含蓄条件句中的虚拟语气的表示愿望的虚拟形式。上述四个要点往往在完形填空或者阅读理解里面存在，尤其是每年完形填空都至少有一道直接考这方面的知识的题目，而在阅读理解里，我们掌握上述四个重点对于我们理解文章的大意和作者态度很有帮助，了解哪些观点是作者假设的、虚拟的，哪些是真实的，这样对于我们回答关于作者态度观点题很有帮助。下面我们将主要从上述四个方面来重点论述在考试中应该注意的问题。一、虚拟语气的常见类型和句型（1）由wish引起的表示愿望的虚拟语气 A．用wish表示对现在的愿望时，它所引起的宾语从句中谓语动词形式为：过去式（be动词用were）。 B．用wish表示对将来的愿望时，它所引起的宾语从句中谓语动词形式为：would, could, might+ 动词原形。 C．wish用于对过去的事实表示一种不可能实现的愿望时，宾语从句中的谓语动词形式为：had+动词过去分词或could, would + have +动词过去分词。 The picture exhibition bored me to death; I wish I had not gone to it. ---“I let Joe borrow our radio for the afternoon.” ---“That’s all right, but I wish he would buy one of his own.” I wish that he weren’t so lazy. (2)had hoped引起的宾语从句中备用语动词形式为would+动词原形，表示一种过去未实现的愿望或令人失望的事。 His father had hoped that his son would go to business with him, but his son became an artist later. (3)would (had) rather, would as soon, would sooner和would prefer所引起的从句中要求用过去式表示当时或将来的情况，用过去完成时表示过去的情况，表示希望或婉转的责备。例如： I’d rather you posted the letter right away. 我倒希望你把这封信立刻寄出去。 I would prefer he didn’t stay there too long.我倒希望他不要在那儿可得太久。 I would just as soon you had returned the book yesterday.我真希望你昨天把这本书还了。（4）I t’s (high, about) time that 句型中that从句中要求用虚拟语气形式，即动词要用过去式。 It’s time that something was done about the traffic problem downtown. It is high time that we put an end to this discussion.现在是我们该结束讲座的时候了。（5）as, 或者whether…or…谓语多用be的原形，引导让步虚拟从句，这种用法通常采用倒装结构：Church as we use the word refers to all religious institutions, be they Christian, Islamivc, Buddhist, Jewish, and so on. The business of each day, be it selling goods or shipping them, went quite smoothly. （6）由连接词in case, so that ,unless, lest ,for fear that引起的状语从句中，谓语动词要用虚拟形式，即should(might, would)+动词原形，例如： She put a blanket over the baby for fear that he should catch cold. 她在那个婴儿身上盖上了毯子以免他着凉。 The bad man was put in the soft-padded cell lest he injure himself. (7) if it were not for…与现在事实相反，if it had not been for与过去事实相反，两个都相当于but for： If it had not been for his help(=but for his help),we would not have succeeded.

高中英语提高之虚拟语气用法

虚拟语气用法虚拟语气用法
概念
虚拟语气用来表示说话人的主观愿望或假想，而不表示客观存在的事实，所说的是一个条件，不一定是事实，或与事实相反。虚拟语气通过谓语动词的特殊形式来表示。英语中的语气分为陈述语气、祈使语气、虚拟语气三类。
应用条件
在表示虚假的、与事实相反的或难以实现的情况时用虚拟语气，表示主观愿望或某种强烈情感时，也用虚拟语气。即当一个人说话时欲强调其所说的话是基于自己的主观想法，而不是根据客观实际，就用虚拟语气。
在非真实条件状语从句中的用法
真实条件状语从句与非真实条件状语从句
条件句可分为两类，一类为真实条件句，一类为非真实条件句。非真实条件句表示的是假设或实际可能性不大的情况，故采用虚拟语气。例： If he doesn’t hurry up, he will miss the bus. 如果他不快点，他将错过巴士。( 真实) If he is free, he will ask me to tell stories. 如果他是空闲的，他会要求我讲故事。（真实） If I were you, I would go at once. 如果我是你，我马上就会去。（非真实，虚拟语气） If there were no air, people would die. 如果没有空气，人就会死亡。（非真实，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.

高中英语虚拟语气的用法

高中英语虚拟语气的用法一、考查虚拟语气在条件从句中的用法时间从句谓语形式（be用were不可改变）主句谓语形式将来一般过去时(be用were) would/should/might/could+动词原形现在一般过去时(be用were) would/should/might/could+动词原形过去现在完成时would/should/might/could+had done （1）If he my advice, he wouldn' t have lost his job. A. followed B. should follow C. had followed D. would follow （2）If we the other road, we might have arrived here in time for the meeting. A. taken B. had taken C. took D. have taken （3） -John went to the hospital alone. -If he me about it, I would have gone with him. A. should tell B. tells C. told D. had told 二、考查特殊句型中的虚拟语气英语中需要使用虚拟语气的特殊句型不多，主理有以下类: 1.“倒装”类虚拟语气当虚拟条件句中含有were, should, had时,有时可将引导虚拟条件句的连词if省略,而将从句中的were,should, had提到句首,构成倒装形式的虚拟语气。如: If he were here, she would agree too.→Were she here, she would agree too.如果她在这里,她也同意的。. If it should rain tomorrow, we should have to put off the match. →Should it rain tomorrow, we should have to put off the match.假若明天下雨,我们只好推迟这场比赛。 If we had found him earlier we could have saved his life.→Had we found him earlier we could have saved his life. 要是我们当时早点找到他的话,我们就可以救活他。注意,如果条件从句的谓语为否定式,其中的否定词not应置于主语之后,而不能与were,should, had等缩略成Weren' t, Shouldn' t, Hadn'场置于句首。如:我如不是警告了你,你就可能丧命了。正: If I hadn' t warned you, you could have been killed. 正: Had I not warned you, you could have been killed. 误: Hadn' t I warned you, you could have been killed. 另外,有时省略if后提前到句首的had可能不是助动词,而是实义动词。如: Had I time, I would go with you.假如我有时间,我就同你们一起去。句中的had不是构成过去完成时的助动词,而是表示“有”,如果不省略if ,完整形式为:If I had time, I would go with you. (1) Had I known about this computer program, a huge amount of time and energy____. (2010浙江卷) A.would have been saved B. had been saved C. will be saved D. was saved （2） fired, your health care and other benefits will not be immediately cut off. (2006湖北） A. Would you be B. Should you be C. Could you be D. Might you be 2.“宁愿”类虚拟语气这里说的“宁愿”主要是指would rather。当它后接句子的时候,句子的谓语通常要用虚
