初中英语虚拟语气

英语中的语气分为陈述语气、祈使语气、虚拟语气三类。

虚拟语气表示说话人的主观愿望或假想,所说的是一个条件,不一定是事实,或与事实相反。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的或实际可能性不大的情

况,故采用虚拟语气。

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 you had come yesterday, you would have met that famous professor.(隐含的事实是:你昨天没来,也没见到那位著名教授)。

虚拟语气的基本形式和用法在含有虚拟条件句的复合句中,主从句的谓语都要用虚拟语气。

1. 含有条件状语从句的复合句

wish(would rather)+宾语从句

suggest(…)+宾语从句

2. 主语从句 It is + adj./p.p/n.+ that+ S+ (should) +do

表语从句S+is that +s + (should) +do

同位语从句 S+that +s +(should) +do

3. 定语从句 It is (high) time that + S + did

I. 含有条件状语从句的复合句(以do为例;S=主语)

时间条件状语从句主句

与现在事实相反的假设 If +S+did…S+would/should/could/might+do…

与过去事实相反的假设 If +S+had done…S+would/should/could/might+have done…

与将来事实相反的假设did…

If+S should do S+would/should/could/might+do…

were to do

注意事项:

1.倒装句。如果条件句中含有功能词had,should,were时,可以省去If,把功能词提前,构成倒装句。2.错综条件句。若条件句和主句动作不存在同一个时间,则谓语形式应根据具体情况而定。

3.If there weren't/had not been +…=without…

4.If it were not for…/If it hadn't been for…= but for…

5.otherwise+虚拟语气的句子

6.虚拟语气的句子,but+ 陈述事实的句子

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。一.一般情况下,英语虚拟语气的形式有下列3种:

语境条件从句主句例子

1.与现在事实相反一般过去式:

were/did

would/should/could/might +

do(动词原形)

If John had the time, he would make a trip to

China to see the Great Wall.

If I were you, I would give up drinking

immediately.

2.与将来事实相反(1). should+动

词原形

(2). 一般过去式:

were/did

(3)、were to+动词

原形

would/should/could/might +

do(动词原形)

If you should lose, what would you do?

If I were to see her tomorrow, I would tell her the

truth.

If you went there next time, you would see what I

mean.

3.与过去事实相反过去完成时:had+

过去分词

would/should/could/might+

have done

If I had arrived earlier, I would have seen David

二.、虚拟语气的几种特殊用法

1.虚拟语气的倒装:将if去掉,谓语动词提前。

如:If I were you, I would give up drinking. =Were I you, I would give up drinking.

If I had arrived earlier, I would have seen David. = Had I arrived earlier, I would have seen David.

2.有时条件从句中的动作和主句中的动作发生的时间不一致,如:

If he had followed the doctor’s advice, he would be quite all right now.

(if从句是对过去的虚拟,主句是对现在的虚拟。)

If I were you, I would have gone home.

(if从句是对现在的虚拟,主句是对过去的虚拟。)

三.虚拟语气的其他用法

1、Suggest, advise 等表示“要求”“建议”的动词之后宾语从句须用虚拟语气,其句子结构如下:

suggest, advise, recommend, demand,

require, insist, urge, request, order, +that…(should )+动词原形

ask, move, propose等

注意:在此结构中that不可省略;should省不省均可。

He suggested that they (should ) stop smoking.

上述动词的名词形式出现时,that 引导的从句仍用虚拟语气。

He made a request that they (should ) stop smoking.

注意:

* insist有两个意思,当表示“坚持让某人做某事”(含命令口吻)时,that从句用虚拟,如:He insists that we (should) go home now.

当表示“坚持某种说法”时,that从句用陈述语气。

He insists that he is right.

*suggest也有两个意思,当表示“建议”时,that从句用虚拟语气,如:I suggest that we should go home now.

当表示“暗示”时,that从句用陈述语气。

如:All the evidence suggests that he stole the money. 所有证据偶读暗示是他偷了钱。

2、It is (was )+necessary, a pity 等+that引导的从句须用虚拟语气,其句子结构如下:

imperative, advisable, 动词完成式

(should) +

It is (was) + important, natural, necessary, +that…

essential, strange,等动词原形

It is important that you (should) follow the doctor’s orders.

It is right that you should have done your homework.

3、wish的用法

主句谓语动词that 从句谓语动词例子

现在的愿望:wish/wishes 一般过去式:did或were I wish I were as tall as you. 我希望和你一

样高。

过去的愿望:wished 过去完成式:had done I wished I had never stopped teaching.

(=I am sorry I stopped teaching.)

对将来的愿望:wish/wishes would/could +动词原形I wish it would rain tomorrow. 我希望明天

下雨就好了。

注意:wish与hope接宾语从句的区别在于:hope表示一般可以实现的希望,宾语从句用陈述语气。wish 表示很难或不大可能实现的希望,宾语从句用虚拟语气。试比较:

(1)We hope they will come,(We don’t know if they can come.)

(2)We wish they could come,(We know they are not coming.)

4、as if, as though, would(had) rather(that)引导的从句须用虚拟语气,如:

He acts as if nothing had happened.

I would rather you didn’t tell him.

动词过去式或should+动词原形,如:

5、It’s (high) time that…+

It’s time (that) you had a hair cut.

It’s high time (that) we took some action.

考研英语语法大全———自己总结

考研英语十二大基础语法体系 对于任何英语句子,要分析其结构,这样才能找到英语语言的规律。每种语言都有它的难点,汉语的难点在于汉语不是拼读语言,汉字很难写,而且有四种声调。其实,许多接触过多种外语的人都认为,英语的语法比法语、德语、俄语、日语等都简单,是最容易学的。著名语言学家乔姆斯基说过,语法是内生的、也就是随着语言的诞生而诞生的。因此,学习语法和学习语言是相辅相成的。 一、英语动词的时态 (一)英汉两种语言在时态表达方式上的差异: 英语的词类与汉语的不同。汉语词类形态稳定,比如“书”这个字,“一本书”、“三本书”都一样,没有词形变化。英语就不同了,book, books仅从词形上就能知道是单数还是复数。 动词是英语中变化最多、最复杂的词类。有人说,学好英语就是学好动词,此言甚是。同一个动作或状态分别在不同时间发生或存在,表达这个动作或状态的动词就要用不同的形式,这就是时态。 (二)英语动词的形式: 英语的时态是通过动词的变化来体现的。因此,了解动词的形式及其变化规律非常重要。英语的实义动词有以下五种形式: (1)动词原形:动词原形在句子中形式不变。主要用于主语为非第三人称单数的一般现在时,情态动词之后, 或根据语法规定必须用动词原形的其他情况。 (2) 一般现在时第三人称单数形式(简称现单三):主要用于主语为第三人称单数的一般现在时。 (3) 过去式:主要用于一般过去时。 (4) 现在分词:主要用于进行时态,或语法规定的其他情况。 (5) 过去分词:主要用于完成时态,或语法规定的其他情况。 动词一般现在时第三人称单数(现单三)的构成,见下表:

即某些字母组合的不规则动词有一定的规律。如:weep→wept, sleep→slept, sweep→swept 以上每个时间段中分别有四种状态:一般、进行、完成和完成进行。因此我们便有了四四一十六个时态。 态(一般、进行、完成、完成进行)。 比如在“They are doing their exercises.”这个句子中,动词由原形do 变成are doing 的形态,说明这个事情是发生在现在、并处于正在进行的状态当中,所以叫现在进行时; 在“They have done their exercises.”这句中,动词由原形do 变成have done的形态,说明这个事情是发生在现在、并处于完成的状态,所以叫现在完成时; 在“They always do their exercises.”中,动词用原形do 的形态,说明这个事情是发生在现在、并且是一般情况下永远如此,所以叫一般现在时。 在这三句话中,动词do 虽然用了不同的形态,其意义没有变化,而是事情发生的时间和状态变了。其余类推。 (三)时态详解 16个时态中,常用的有12个:一般现在时、一般过去时、一般将来时、过去将来时、现在进行时、过去进行时、将来进行时、现在完成时、过去完成时、将来完成时、现在完成进行时和过去完成进行时。其他时态很少单独使用。 下面把各种时态的构成和用法做一个全面的介绍。

考研英语完形填空--红花绿色词原则完整版本

两大原则,力保四分 第一:红花绿叶原则 每次出现,每次都选的单词为红花词。每次出现,每次都不选的词为绿叶词。 红花词(按排名):however,also,yet,while,because(一定背着,很重要) 绿叶词:是见到后不选的词:排名第一的是:since,而且谁跟since谁倒霉,since家族都不选,同义词:eversince,nowthat一次都没选过。 还有绿叶词:what,它是著名的说和关系词,不选。What不能跟在名词后,就不能引导定语从句和同谓语从句。而定语和同谓语是考试的大热门。所以它是个绿叶词。 还有两拨绿叶词,一个是涉及到虚拟语气的词。而在考研的历年考题中却出现得很少,是因为考研完型填空选材因素,完型填空都选于比较严肃的话题,而虚拟语气不能适应严肃的场景,故出现得很少。 排第一的是:If only;要想了解这个词,还有only if ,only if就是if;但if only却不是only,only if既不是红花也不是绿叶。 If only用英文来解释的话,相当于I wish,相当于要是,只要,要是什么什么多好呀。 If only的用法,它的后面跟从句,从句的时态,如果与过去的情况相反,从句用过去完成时。如果与现在情况相反,从句用一般过去时。如果从句与将来的情况相反,从句用过去将来时,用would/could+动词原形。 If only或者I wish后面跟句子,它后面的句子都是过去时态,这也是是否选此词的依据。如果不是过去时,直接排除! 例 44 its economy continues to recover, 44.[A] Even though [B] Now that [C] If only [D] Provided that 所以不选C A variety of activities should be organized 35 participants can remain active as long as they want and then go on to 36 else without f eeling guilty and without letting the other participants 37 . 35.

初三英语虚拟语气讲解及练习题

浅谈初中英语虚拟语气的用法 一.语气的概念 英语动词不仅有时态、语态等的变化,而且还有语气的变化。语气和时态、语态一样都是英语的语法现象。 从形式上看,语气是动词的一种变化形式。 从意义上讲,语气是表示说话人对某一行为或某一事情的看法和态度。根据说话人的意图,语气可分3种: ⑴直陈语气(又叫陈述语气)——用来陈述事实(或提问题)等。可以用于陈述句,也可以用于疑问句或感叹句。 ⑵祈使语气——用来提出请求或命令等。主要用于祈使句。 ⑶虚拟语气——见下面。 语气和时态是截然不同的概念,但语气要通过动词的时态形式表示出来。 二.虚拟语气 ㈠概念通常是表示说话人所说的话不是一种事实,而是一种纯粹的假设、虚拟、主观愿望或建议等。可以用于陈述句,也可以用于疑问句等。 ㈡动词形式虚拟语气的动词形式大多数情况是用动词(相应)的过去时(相对直陈语气而言)。动词be若用过去式时可以一律用were。 ㈢应用 ⑴在含有条件状语从句的复合句中的应用。表示纯粹的假设,或可能性很小的情 况。主从句的谓语动词主要形式如下: 例:1)If I were you, I’d wear a shirt and tie. 2)What would you do if you had a million dollars ? 3)If you had come a few minutes earlier, you would have met him. 4)If he hadn’t been strict with himself, he wouldn’t have made such progress. ⑵在wish等宾语从句中的应用。表示纯粹的主观愿望,不可能实现的,或实现的可能性极小的情况。宾语从句谓语动词根据具体情况常可用一般过去时,过去将来时或过去完成时等。 例如: 1)I wish that I could help him now. 我现在要是能帮上他该多好啊!或我多么希望现在能帮上他!(言下之意:我现在帮不上他,没能力帮助他) 2)I wish I could come here tomorrow. 明天我要是能来这儿就好了!(言下之意:我明天根本不可能来这儿,或我明天能来这儿的可能性很小) 3)We wish he hadn’t gone. 他要是没有走该多好啊! ⑶用在suggest等的宾语从句中,表是纯粹的建议。 句型为:suggest(ed) that … (should) + 动词原形…(should可省略) 1)He suggests that we (should) visit the museum. 2) We suggested that he _____ here every day. A. come B. comes C. came D. can come E. could come 虚拟语气的几种特殊用法 1.省掉if的条件从句结构: Had you asked me, I would have told you. (=If you had asked me,…) 2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示,如: A true friend would not do such a thing. (=If he were a true friend, he...) (=If there were no water,…) (=If you hadn’t helped me,…)

(完整word版)初中英语语法专项虚拟语气

初中英语语法专项练习十四——虚拟语气 1. When a pencil is partly in a glass of water, it looks as if it _______. A.breaks B.has broken C.were broken D.had been broken 解析:答案为C。本题考查的是as if 引导的让步状语从句中的语气问题,as if引导的状语从句如果与事实一致,不用虚拟语气,如果与事实相反,应用虚拟语气。题中“当铅笔的一部分浸在水中,铅笔看上去好像断了”。而实际上铅笔并未断,与事实相反,前半部分陈述是一般现在时,因而本句是对一般现在时的虚拟,用were broken。 2. I didn't see your sister at the meeting. If she ___________, she would have met my brother. A.has come B.did come C.came D.had come 解析:答案为D。本题考查的是if条件句中的虚拟语气。题意是:我在会议上没看到你姐姐,故你姐姐没来。因此如果“她来了”与事实相反,前面一句交代了虚拟语气的时态是一般过去时的虚拟,所以if从句中用had+过去分词。 3. —If he ___________, he ________that food. —Luckily he was sent to the hospital immediately. A.was warned; would not take B.had been warned; would not have taken C.would be warned; had not taken D.would have been warned; had not taken 解析:答案为B。本题考查的是条件状语从句与主句表示与事实相反时虚拟语气的用法。根据下一句语境可知,他事先并没有得到警告,表示过去时间的虚拟语气,故选B。 4. If there were no subjunctive, English ______ much easier. A.will be B.would have been C.could have been D.would be 解析:观察题干,可知全句表达的是与现在事实相反的虚拟语气。故答案为D。 5. The guard at the gate insisted that everybody ______ the rules. A.obeys B.obey C.will obey D.would obey 解析:根据insist后的宾语从句谓语要用(should) do形式规律,可定正确答案是B。 6. I wish I _____ you yesterday. A.seen B.did see C.had seen D.were to see 解析:此题表与过去事实相反的原望,答案应为C。 7. ——If he _____ , he _____ that food. ——Luckily he was sent to the hospital immediately. A.was warned;would not take B.had been warned;would not have taken C.wuld be warned;had not taken D.would have been warned;had not taken 解析:从对话看,是表达与过去事实相反的虚拟语气,故答案为B。 8. Without electricity human life _____ quite different today. A.is B.will be C.would have been D.would be 解析:without引出一个含蓄条件句,主句表述的是与现在事实相反的虚拟语气,故答案为D。 9. When a pencil is partly in a glass of water, it look as if it _____. A.breaks B.has broken C.were broken D.had been broken
