考点一 虚拟语气在非真实性条件句的运用

要点归纳:

真实条件句:假设的情况是有可能发生,谓语要用陈述语气。

条件句

非真实条件句,即虚拟条件句。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。

e. g. If it doesn’t rain tomorrow, we will go to the park.

If he had seen you yesterday, he would have asked you about it.

虚拟语气结构列表如下:

e.g. If he were here, everything would be all right.

从句(条件句) 主句(结果句) 与现在事实相反的假设

If +主语+动词过去式(were ) 主语+ should/would/could/might +动词原形 与过去事实相反的假设 If +主语+ had +过去分词

主语+ should/would/could/might + have +过去分词

与将来事实相反的假设 1. If +主语+动词过去式 2. If +主语+ were to +动词原形 3. If +主语+ should +动词原形

主语+ should/would/could/might +动词原形

If her mother had taken the doctor’s advice, she would/might have got well earlier.

If it were to rain tomorrow, the match would be canceled.

1、错综时间条件句

有时条件从句的动作和主句动作发生的时间不一致,这时需根据意思采用表示不同时间的动词形式来进行调整。

If she had taken the doctor’s advice, she might still be alive.

If I were you, I would have accepted their terms.

2、if省略句,采用局部倒装语序。把had /should/were等动词(不包括行为动词)移到从句

的句首。

If I were at school again, I would study harder.

Were I at school again, I would study harder.

If it should rain tomorrow, we would not go climbing.

Should it rain tomorrow, we would not go climbing.

If you had come earlier, you would have caught the bus.

Had you come earlier, you would have caught the bus.

3、含蓄条件句:

有时候假设的情况并不用条件从句表示出来,而是通过其他手段来表示。(without/but for/otherwise/or/but)

Without air (If there were no air), there would be no living things.

But for your help (If it hadn’t been for your help), I couldn’t have done it.

【小试牛刀】

How good a teacher she is!她是多好的一位老师啊! b.祈使语气:表示说话人对对方的请求或命令。如: Never be late again! 再也不要迟到了。 Don’ t forget to turn off the light. 别忘了关灯。 c.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 a bird, I could fly in the air.如果我是一只小鸟,我就能在空中飞行。 对比: If I am a bird, I can fly in the sky. 二.虚拟语气在条件从句中的用法。 条件从句有两类,一是真实条件句,另一是虚拟条件句。如果假设的情况可能发生,是真实条 件句,这种情况下谓语用陈述语气。如: If time permits, we ’ ll go fishing together. 如果时间允许,我们就一起去钓鱼。 如果假设的情况是不存在的或不大可能发生的,则是虚拟条件句。如: If time permitted, we would go fishing together. (隐含的事实是:时间不允许,我们不会一起去 钓鱼)。 三.例句与练习: 1.表示与现在事实相反的假设和结果。 If I were you, I should(would ,could, might)tell him the truth.要是我是你,我就会告诉他 真相了。(事实上我不是你) If she had time, she would(could, might)help me.如果她有时间,她就会帮我。(事实上她 没有时间) 练习: 1, If the color of your dress ____ red, you _____ look more cheerful. 2, If I ____(have to) say something good about your work, I ______ say“ well done”.

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)

英语总复习虚拟语气知识点(大全)

英语总复习虚拟语气知识点(大全) 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.I suggest that we Chinese people_______Chinese culture with love and joy everywhere we go. A.spread B.spreading C.to spread D.will spread 【答案】A 【解析】 【详解】 句意:我建议我们中国人无论走到哪里都要带着爱心和欢乐来传播中国文化, 考查动词suggest后跟虚拟语气。spread是动词原形;spreading是动名词;to spread是动词不定式;will spread是一般将来时。动词在这里suggest表示建议,后面宾语从句中使用虚拟语气should+动词原形,should可以省略。根据句意说明本句的suggest表示建议,故后面使用虚拟语气,省略了should,故选A。 【点睛】 动词suggest 后面可以跟名词作宾语,用于句型“suggest sth.”。如:I suggested a visit. 我提议参观。 suggest 后跟动名词作宾语,如:He suggested going home. 他提议回家。 suggest后面跟that引导的宾语从句时,用虚拟语气,一般省略情态动词should,所以本题选项是A。 3.You _______ through that red light, for you _______ an accident. A.must have driven; should have caused B.could have driven; might have caused C.couldn’t have driven; should have caused D.shouldn’t have driven; could have caused 【答案】D 【解析】 【详解】 句意:你不应该开车闯红灯,因为你会引起事故的。 考查情态动词。分析句子及选项“You ___ through that red light, for you____ an accident.”, 你开车闯红灯,因为你事故的,可知是对过去的虚拟,应用情态动词+have done。此处

牛津高中英语虚拟语气的全部考点和记忆技巧

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.

高考英语考点归纳(四)—虚拟语气

虚拟语气 虚拟语气表示说话人的愿望,假设,猜测或建议,而不是表示客观存在的事实。高考考查虚拟语气主要和情态动词相结合。 1 (1be动词的过去式用were”。如: ?. If I were a boy, I would join the army. ? (2 则用过去分词” ? (4)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作相应调整。如: ?. If they had worked hard, they would be very tired.(从句说的是过去,主句指的是现在) ?. Were I a boy, I would join the army. ?. Had he taken my advice, he would have succeeded. ?. Were it not for the expense, I would go to Britain. 2、虚拟语气用于名词性从句 ( ①。表示不能实现的愿望,译为“要是……就好了”等。 表示将来不能实现的愿望,从句中的谓语动词用“would/could + 动词原形”; 表示过去不能实现的愿望,从句中的谓语动词用“had + 过去分词”或“could(should) + have + 过去分词”。如: ?. I wish it were spring all the year round. ?. I wish I had known the answer. ? suggest, advise, propose, demand, require, insist, request, should + 动词原形或是动词原形。如:?. She suggested we (should) leave here at once. ? (2 作表示建议、 等的表语从句和同位语从句,从句中的谓语动词用“(should)+ 动词原形”。如: ?. His suggestion that we (should)go to Shanghai is wonderful. ? (3 “should + 动词原形”

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.

虚拟语气用法总结讲课稿

虚拟语气用法总结

虚拟语气用法总结 朱世梅 新时代大学英语中针对虚拟语气的练习题较多,而学生们往往把握不好虚拟语气的正确使用,现将其用法总结如下: 一.虚拟语气在英语里主要用来表达: a. 非真实的情景,不可能发生的事,即某种与事实相反或难以实现的情况,或说话人主观愿望。 b. 与客观事实相反地情景,即强制性虚拟语气,表示建议、命令、劝告这一类的意思上,表示强烈的要求做到、必须做到这样的含义。 c. 虚拟语气的表达形式是通过动词的变化形式表达的,其特点是主从句时态的不一致,而且一般有明显得标志。 二.虚拟语气的考点为: 1.If 句型 (共有三种句型) 非真实条件句: a.与现在的事实相反:从句用一般过去时,主句的谓语用would (could, might) +动词原形 If I were Bill Gates, I would not work so hard every day. b.与过去的事实相反:从句用过去完成时,主句的谓语用would (could, might) +现在完成时 If I had gone to America when I graduated from middle school, I would have got my PhD degree. c.与将来的事实相反:从句用should (were to,did) + 动词原形,主句的谓语用would (could, might) +动词原形 If it should/were to snow tomorrow, I would go skiing.

注意:虚拟条件句的倒装虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略,再把were, should或had 移到从句句首,实行倒装。 Eg: Should it rain, the crops would be saved. =Were it to rain, the crops would be saved. Eg:_____ to do the work, I should do it some other day. A. If were I B. I were C. Were I D. Was I 答案C. 在虚拟条件状语中如果有were, should, had这三个词,通常将if省略,主语提前, 变成 were, should, had +主语的形式。但在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do. d.混合条件句主句与从句的动作发生在不同的时间,这时主,从句谓语动词的虚拟语气形式因时间不同而不同,这叫做混合条件句。例如:条件句动作发生在过去,主句的动作发生在现在)谓语动词要根据表示的时间进行调整。 Eg: If it had rained last night (过去), it would be very cold today (现在). 2.Wish 句型表达“但愿…,要是…多好”的语气表示与事实相反的情况,或表示将来不太可能实现的愿望。其宾语从句的动词形式为: He wished he hadn't said that. 他希望他没讲那样的话。 I wish it would rain tomorrow. 我希望明天下雨就好了。 Wish to do表达法: Wish sb / sth to do I wish to see the manager. = I want to see the manager. I wish the manager to be informed at once. (= I want the manager to be informed at once.) 3.在强制性语气的宾语从句中的运用即表示建议、命令、劝告、决心等主观色彩的动词 + that + (should) + 动词原形,其中should 经常被省略。这类动词包括: suggest, propose, recommend, demand, order, command, desire, require, insist,
