虚拟语气

用法及动词形式

1、表示与现在事实相反的情况:

从句:If 主语+过去时

主句:主语+should/would/could/might+do

eg: 

1.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)

2.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。(事实:不知道)

3.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)

4.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)

5.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:没有努力)

6.she looked at me as if I had been a

stranger.

她看我的样子好像我是一个陌生人。(事实:我并非陌生人) 

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/could/might+have

done 

eg:

1. 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。

now.

如果他们通知过我们的话,我们现在就不会来这里了。

②从句的动作与现在事实相反,而主句的动作与过去事实不符。

如:

If he were free today,we would have sent him to Beijing.

如果他今天有空的话,我们会已经派他去北京了。

If he knew her,he would have greeted her.

要是他认识她的话,他肯定会去问候她了。

5、 当虚拟条件句的谓语动词含有were,should,had 时,if可以省略,这时条件从句要用倒装语序,即把were,should,had等词置于句首,这种多用于书面语。eg: Should he agree to go there,we would send him there.

要是他答应去的话,我们就派他去。

Were she here,she would agree with us.

如果她在这儿的话,她会同意我们的。

Had he learnt about computers,we would have hired him to work here.

如果他懂一些电脑知识的话,我们已经聘用他来这里工作了。

6、非真实条件句中的条件从句有时不表达出来,只暗含在副词、介词短语、上下文或其他方式表示出来,这种句子叫做含蓄条件句,在多数情况下,条件会暗含在短语中,如without…,but for…等

eg:

But for his help,we would be working now.

要不是他的帮助,我们还会在工作呢。

Without your instruction,I would not have made such great progress.

要是没有你的指导,我不会取得如此大的进步。

We didn't know his telephone number,otherwise we would have telephoned him.

我们不知道他的电话号码,否则我们就会给他打电话。

目的状语从句

1、在for fear that,in case,lest引导的从句中,若用虚拟语气时,从句谓语为:should + do。并且 should 能省略

She examined the door again for fear that a

thief (should) come in.

她又把门检查了一遍,以防盗贼的进入。

He started out earlier lest he (should) be

late.

他早早的就出发了以防迟到。

2、在so that,in order that所引导的目的状语从句中,从句中的谓语为:can / could / may / might /

will / would / should + do。

He goes closer to the speaker so that he can hear him clearer. 他走近说话的人以便能听得更清楚。

He read the letter carefully in order that he should not miss a word. 他把信读得很仔细以便不漏掉一个字。

宾语从句与虚拟语气

1、一想要(desire)一宁愿(prefer)二命令(order. command)三建议(advise. suggest. propose/recommend)四要求(demand. require. request. ask.insist)中,无论主句谓语动词为何种时态,从句的谓语动词都用:"should + do"。should可以省略。eg:

He suggestedthat we (should) take the teacher's advice.

He insisted that we (should) take the teacher's advice.

He demand that we (should) take the teacher's advice.

He orderedthat we (should) take the teacher's advice.

insist意为“坚持某种动作”才用虚拟语气;意

为“坚持某种观点,某个事实”则不用虚拟语气。

Do you think it is necessary that he

(should)not be sent to Lingbao.

It is srange that such a person should be our friend.

奇怪的是这样一个人会成为我们的朋友。

虚拟语气与状语从句

3、 在even if,even though 所引导的让步状语从句中用may/might+动词原形,may/might可以省略,表示与现在相反的情况;从句用过去完成时,表示与过去相反的情况,类似的词有though/even

though/whatever/however/so long as; 主句、从句的结构与if所引导的条件从句结构相同。

eg:

Even if he were here himself,he should not know what to do.

即使他亲自来也不知该怎么办。(事实:他没来)

Nobody could save him even though Hua Tuo

should come here.

即使华佗在世也救不了他。(事实:华佗不在世)

4、 在whatever,whichever,whenever,whoever,wherever,however,no matter wh-等引导的让步状语从句中,从句虚拟语气结构为:

指现在或将来:may +do。

eg:

We will finish it on time no matter what may happen.

不管发生什么事,我们都要按时完成。

We will find him wherever he may be.

无论他在哪里,我们都要找到他。

I will wait for him no matter how late he may come.

不管他来的多么晚,我都会等他。

指过去:may +have done 。

eg:

You mustn't be proud whatevergreat progress you may have made.

不管你取得了多么大的进步,你也不能骄傲。

We must respect him no matter what mistakes he may have made.

不管他犯过什么错误,我们必须尊敬他。

6、虚拟语气还可用在定语从句中,表示:“早该做某事了”时,定语从句中的谓语动词须用虚拟语气,其虚拟语气的结构为:It is (high / about) time that + 主语+动词的过去式/ should + do(优先使用动词过去式),即从句用虚拟过去式。

It is time that I went to pick up my daughter

at school.

我该去学校接我的女儿了。

It is high time you should go to work.

你早该上班了。

高考虚拟语气用法详解()

高考虚拟语气用法详解 一·语气概述 和时态语态一样,语气也是谓语动词的一种形式,它表明说话者的目的和意图。英语中有三种语气:陈述语气,祈使语气和虚拟语气。(有的语法书说语气有四种,即还包括疑问语气)。 eg:①He doesn’t see very well in his right eye .他右眼视力不太好。(陈述语气) ②Have they ever been to Australia ?他们去过澳大利亚没有?(疑问语气) ③Please read through the instruction in advance .请先通读说明书。(祈使语 气) 二·虚拟语气概述 在英语中,由于说话人的意图不同,动词需用不同的形式,称为语气。虚拟语气是指说话人表示一种假设的情况,一种愿望,怀疑,推测,请求等,即认为动词所表示的动作或状态并非事实。虚拟语气可用于状语从句,名词性从句,定语从句及其他结构中。 三·非真实条件句中的虚拟语气 真实条件句(遵循主将从现原则) A.由If引导的两种条件句: 非真实条件句(虚拟语气) 以下为If在非真实条件句中虚拟语气的形式和用法: 假设类型If从句主句 与现在事实相反did (be用were)should/would/ could/might do 与过去事实相反had done should/would/ could/might have done 与将来事实相反1)did 2)were to do 3)should do should/would/ could/might do eg:①If I were you ,I would reconsider their advice .如果我是你的话,我会重新考虑他们的意见。(与现在事实相反) ②You would not have caught a cold if you had put on more clothes .如果你多穿了些衣服,你就不会得感冒了。(与过去事实相反)

虚拟语气用法总结及详细解析

虚拟语气用法 英语中的语气分为陈述语气、祈使语气、虚拟语气、疑问语气和感叹语气五类。 1、表示动作或状态是客观存在的、确定的或符合事实的,用于陈述句、疑问句和某些感叹句中。 China is an Asian country. (肯定句) How interesting my stay in China has been! (感叹句) 2、祈使句表示说话人对对方的请求、警告,建议或命令。如: Please come over here. 请到这边来。 Watch your steps! 当心!(走路) 3、虚拟语气表示说话者做出的假设而非事实,或难以实现的情况,甚至表达彻底相反的概念。此外,如需表达主观愿望或某种强烈的感情时,也可用虚拟语气。虚拟语气是由句中的谓语动词的特殊形式表示出来的。如: If I were a bird,I would be able to fly in the air. 如果我是一只小鸟,我就能在空中飞行。 I wish I could pass the examination. 我希望我能通过考试。

If there were a heavy snow next Sunday, we would not go skating. 如果下周日下大雪,我们就不能去滑冰了。 If she were to be here next Monday, I would tell her about the matter. 如果她下周一来这儿的话,我就会告诉她这件事的始末。 4、有时,虚拟条件句中,结果主句和条件从句的谓语动作若不是同时发生时,虚拟语气的形式应作相应的调整。这种条件句叫错综条件句。 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。 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 If they had informed us, we would not come here now. 如果他们通知过我们的话,我们现在就不会来这里了。 ②从句的动作与现在事实相反,而主句的动作与过去事实不符。 If he were free today, we would have sent him to Beijing. 如果他今天有空的话,我们会已经派他去北京了。 If he knew her, he would have greeted her. 要是他认识她的话,他肯定会去问候她了。 5、当虚拟条件句的谓语动词含有were, should, had时,if可以省略,这时条件从句要用倒装语序,即把were, should, had等词置于句首,这种多用于书面语。 Should he agree to go there, we would send him there.要是他答应去的话,我们就派他去。 Were she here, she would agree with us.如果她在这儿的话,她会同意我们的。 Had he learnt about computers, we would have hired him to work here. 如果他懂一些电脑知识的话,我们已经聘用他来这里工作了。 【注意】 若条件从句为否定句,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't而置于句首。 Had it not been for the bad weather we would have arrived on time. 若不是天气坏,我们就准时到达了。 ②有时省略if后提前的had不是助动词: Had I time,I would come. 假若我有时间,我会来的。(=If I had time…) 6、非真实条件句中的条件从句有时不表达出来,暗含在副词、介词短语、上下文或其他方式表示出来,这种句子叫做含蓄条件句。 ①将条件会暗含在介词短语中,如without…, but for…,otherwise(要不是因为)等 But for his help, we would be working now. (要不是他的帮助,我们还会在工作呢。

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:

虚拟语气用法详解

虚拟语气用法详解 一、条件句中的虚拟语气 1.条件句中虚拟语气的形式 从句中提出一种与客观现实不相符或根本不可能存在的条件,主句会产生的一种不可能获得的结果。条件句中的虚拟语气根 2. 条件句中的虚拟语气的举例 (1) 将来时的条件句中的虚拟语气。如: If he should go to Qing Hua Univer sity, he would make full use of his time. If he were to come here, he would tell us about it. (2) 现在时的条件句中的虚拟语气。如: If he were free, he would help us.

If he studied at this school, he wo uld know you well. (3) 过去时的条件句中的虚拟语气。如:If I had seen the film, I would have tol d you about it. If I had got there earlier, I would have met Mr. Li. 3.运用条件句中的虚拟语气时,须注意的几个问题 (1) 有时,虚拟条件句中,主、从句的动作若不是同时发生时,须区别对待。 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. If they had informed us, we would not come here now. (2) 当虚拟条件句的谓语动词含有wer e, should, had时,if可省略,而将were, s hould, had等词置于句首。如: Should he agree to go there, we wo uld send him there. Were she here, she would agree wit h us. Had he learnt about computers, we would have hired him to work here. (3) 有时,句子没有直接给出假设情况的条件,而须通过上下文或其他方式来判断。如:

虚拟语气用法归纳

虚拟语气用法归纳 1、在非真实条件句中,谓语动词用虚拟语气。非真实条件有以下三类: (1)与现在事实相反的非真实条件句,谓语动词形式如下: 从句:过去时 主句:would/should/could/might+动词原形。如 If I were you, I would ask our teacher for advice. 如果我是你的话,我就请教老师。 (2)与过去事实相反的非真实条件句,谓语动词形式如下: 从句:过去完成时 主句:would/should/could/ might +have+动词过去分词。如 If I hadn’t taken the wrong bus, I wouldn’t have missed the contest. 如果我没有搭错车,我就不会不参加竞赛。 (3)与将来事实相反的非真实条件句,谓语动词形式如下: 从句:过去时/should /were to +动词原形 主句:would/should/could/might+动词原形。如 If I had enough money next month, I would buy a copy of “The Advanced Learner’s Dictionary of Current English”. 如果我下个月有足够的钱,我就会买一本《现代高级英语学习词典》。 (4)混合时间条件句:主句和从句不一定用指同一时间的动词。如 If I had learned French, I would be able to interpret for our French friend. 假如我以前学过法语,现在就能给我们的法国朋友当翻译。 (注:if从句与过去事实相反,用过去完成时;而主句与现在事实相反,用would+动词原形。)

可用虚拟语气的用法总结

虚拟语气的用法总结 语气:语气是动词的一中形式,它表示说话人对某一行为或事情的看法和态度。 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 you, I should study English. 一.虚拟语气在条件从句的用法 条件句有两类,一类是真实条件句;一类是非真实条件句,也就是虚拟条件句。 如果假设的情况是有可能发生的,就是真实条件句,谓语要用陈述语气。如If it doesn’t rain tomorrow, we will go to the park. 如果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的,则是虚拟条件句。如If he had seen you yesterday, he would have asked you about it. 在含有虚拟条件句的复合句中,主句 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. 有时候省略if,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。例如: Were it to rain tomorrow, our picnic would be canceled. Had it not been for the storm, we would have arrived in time. Should the earth stop running, what would happen? 二. 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,这时需要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. 三.含蓄条件句

虚拟语气用法小结及练习(附答案)

虚拟语气用法小结及相关练习(附答案) 一、虚拟语气在条件从句中的用法 条件句有两类,一类是真实条件句,一类是虚拟条件句。如果假设的情况是有可能发生的,就是真实条件何。在这种真实条件句中的谓语用陈述语气。如: If it doesn’t rain tomorrow, we will go to the park. 如果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的,则是虚拟条件句。如: If he had seen you yesterday, he would have asked you about it. 如果他昨天见到你,他会问你这件事的。(事实上他昨天没见到你,因此也未能问你这件事。) 1. 在含有虚拟条件句的复合句中,主句和从句的谓语都要用虚拟语气。虚拟 2. 错综时间条件句: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(表示错综时间的虚拟语气),这时动词的形式要根据它所表示的时间加以调整。 If you had listened to the doctor, you would be all right now. 如果你当初听了医生 的话,身体现在就好了。(从句动作指过去,主句动作指现在) 3. 省略连词if (倒装)。在书面语中,如果虚拟条件从句中有were,had 或should,可以把if省略,把这几个词放到主语之前,构成主谓倒装。 Should he come (If he should come), tell him to ring me up. Were I you (If I were you), I would not do it. Were I to meet him tomorrow (= if I were to met him tomorrow), I should ask him about it. 要是我明天见到他,我就会问他这件事的。

英语虚拟语气用法详解

英语虚拟语气用法详解 1. 英语语气的概念 英语有三种语气,即陈述语气、祈使语气和虚拟语气。陈述语气用于陈述事实、提出看法或问题等,祈使语气用于表示请求、命令或警告等,虚拟语气则表示假想或主观愿望。如: I like this book the best. 我最喜欢这本书。(陈述语气) Don’t be so careless. 不要如此粗心大意。(祈使语气) I suggest that we should go tomorrow. 我建议我们明天走。(虚拟语气) If you dropped the glass, it would break. 假如你把玻璃杯掉在地上,它会打碎的。(虚拟语气) 3. 虚拟条件句的基本类型 (1) 与现在事实相反:若与现在事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”。如: If we left now, we should arrive in good time. 假如我们现在就走的话,我们就会及时到达。 (2) 与过去事实相反:若与过去事实相反,条件从句的谓语用过去完成时(had+过去分词),主句谓语用“should (would, coul d, might)+have+过去分词”。如: If he had been in that train then, he might have been k illed in that accident. 如果当时他也在那列火车上,他可能就死于那场车祸了。

(3) 与将来事实相反:若与将来事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”。如: If he went,would you go too? 如果他去,你也去吗?(大概他不会去) If I asked him,I’m sure he’d help us. 如果我向他提出要求,肯定他会帮助我们。(不过我不打算这样做) 3. 错综时间虚拟条件句 所谓错综时间虚拟条件句即条件从句与主句所指时间不一致,如从句指过去,而主句即指的是现在或将来,此时应根据具体的语境情况,结合上面提到的三种基本类型对时态作相应的调整。如:If you’d listened to me, you wouldn’t be in such tro uble now. 如果你听了我的话,你现在也不会有这样的麻烦了。 If you were in better health, we’d have let you go wit h us. 你要是身体好一点,我们就让你和我们一道去了。 4. 含蓄虚拟条件句 所谓含蓄虚拟条件句即指将条件从句隐藏在上下文一定的短语中的一类条件句。如: Anybody else would have believed you. 任何别人都会相信你的话了。 Without your help, I couldn’t have achieved all this. 要不是有你帮助,我不会取得这些成就。 I would have written before, but I have been ill. 我本想给你写信的,但我生病了。 5. if it weren’t (wasn’t) for与if it hadn’t been for

虚拟语气的几种用法

虚拟语气的几种用法 1.错综时间条件句 虚拟语气通常用于含条件状语从句的主从复合句中。条件状语从句中表示与现在、过去或将来事实相反的虚拟语气比较容易掌握,但绝不可把它们当作一成不变的数学公式一样对待。就是说,不能只单纯背语法条条框框,而应充分理解句子锁定的语言环境。有时从句动作与主句动作发生的时间不一致。这时就要根据各自表示的时间概念加以调整。如: If he had taken my advice, he would be much better now.(从句与过去事实相反,主句与现在事实相反。) 2.含蓄条件句 有时假设的情况并不是以条件状语从句的形式表示出来,而是通过一个介词(如:without; butfor)引出的短语,一个连词(如:but; or; otherwise)引出的从句或其它方式来表示。如:Without your help, we couldn’t have finished the job in time.(Without your help=If you hadn’t helped us) He could have given you more help, but he was busy.(but he was busy=if he had not been busy) 3.倒装句 如从句中有were, had或should,则可以省去if, 并将were, had或should提前到句首,构成部分倒装。如: Were I to be young again, I would study medicine.(从句正常语序为:If I were to be young again) Had you not left so early, you might have missed the train.(从句正常语序为:If you had not left so early) 4.错综语气 有时从句用虚拟语气,主句却用陈述语气或祈使语气。如: If there should be an earthquake, what will you do﹖ (从句用虚拟语气,主句用陈述语气。) Ask her to leave a message if she should come.(从句用虚拟语气,主句用祈使语气。) 5.It is (high) time (that)句型 这个句型往往用“过去时”形式表示“现在”的动作,有时也用“should+动词原形”。如:It’s high time (that) we began to work. I think it’s time (that) you made up/should make up your mind. 6.主句中含有suggest, suggestion, propose, proposal, insist, order, demand, request等词时,从句谓语部分常用“(should)+动词原形”。如: She suggests that they (should) go there right away. Her suggestion is that they (should) go there right away.

虚拟语气用法归纳 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,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) 2. If you had not watched television so late last night, you would not be so sleepy now.( 从句是对过去的假设,主句是对现在的假设) 3. If I were you, I would seize the chance to go abroad. (从句和主句都是现在的假设) 4. Had you followed the doctor’s suggestion, you would be fine now.( 从句是对过去的假设,主句是对现在的假设) 5. If I had made some money last summer, I would go on holiday next month.( 从句是对过去的假设,主句是对将来的假设) 6. You didn’t let me drive. If we had driven in turns, you wouldn’t be so tired now. (从句是对过去的假设,主句是对现在的假设) 7. If Jack hadn’t met Rose on his voyage, he would be alive now. (从句是对过去的假设,主句是对现在的假设)

虚拟语气用法大全

1.虚拟语气在条件句中的用法 (1)若表示与现在事实相反的假设,则条件从句中用过去式,主句中用过去将来式(would,should,could,might + 动词原形);若表示某事将来实现的可能性不大,则条件从句中用should + 动词原形也可用“were to+动词原形”或用过去式动词。如: 2)若表示与过去事实相反的假设,从句中用过去完成式,主句中用过去将来完成式(should,would,could,might + have + 过去分词)。如: busy. (3)含有虚拟语气的条件状语从句中,如有had,should,were 这三个词的话,在正式或书面语言中可将if省略,再将句子的主语和谓语动词实行全部倒装或部分倒装。如: (4)若主句从句所指的时间不一致,即条件从句表示与过去事实相反,主句表示与现在事实相反;或者条件从句表示与现在事实相反,主句表真实情况,则从句中应采用与具体时间相对应的虚拟形式。如: 2.虚拟语气在宾语从句中的用法 在动词suggest,order,demand,propose,request,command,insist等后的宾语从句中,用虚拟语气(即Should+动词原形或只用动词原形)来表示愿望、建议、命令、请求等。在动词wish /would rather后的宾语从句中,用过去式表示与现在事实不符,用过去完成式表示与过去事实不符。如: 3.虚拟语气在主语从句中的用法 在It is necessary/important/strange/natural;It is requested/suggested/desired/proposed;it is a pity等结构后的主语从句中要用虚拟语气,即Should+动词原形或只用动词原形。如: 4.虚拟语气在表语从句、同位语从句中的用法。 在 suggestion, proposal,idea,plan,order,advice等名词后的表语从句、同位语从句中要用虚拟语气,即should+动词原形或只用动词原形 5.虚拟语气在其他状语从句中的用法 在as if引导的状语从句中,用过去式表示与现在事实不符,用过去完成式表示与过去事实不符;在so that,in order that引导的状语从句中,常用should/would/could/might+动词原形来表示虚拟语气。 6.虚拟语气在定语从句中的用法: 在it is time后面的定语从句中常用过去式表示虚拟语气。 虚拟语气(Subjunctive Mood)这一语法项目是各类英语考试中心测试的重点之一。虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测。 Ⅰ用以表示虚拟条件的虚拟语气 ⒈ 用if条件从句表示的虚拟条件,是虚拟条件最普通的方式。 ① 虚拟现在时表示与现在事实相反的假设,其if 从句的谓语形式用动词的过
