虚拟语气,又称假设语气,是谓语动词的一种形式,表示说话人叙述的内容与事实相反,在现实中并不存在,或实现的可能性很小。

一、动词的语气

语气可以用来区别讲话人对某一行为或事情的看法和态度。英语中的语气有三种,分别是陈述语气、祈使语气和虚拟语气。

(一)陈述语气

陈述语气一般用来叙述事实或就事实提出询问,主要用于陈述句、疑问句和某些感叹句。

Where there is a will, there's a way.

有志者事竟成。

Can you help me carry the box upstairs.

你能帮我把箱子搬到楼上吗?

How I missed the life in the countryside!

我多么想念乡村的生活啊!

(二)祈使语气

祈使语气表示说话人向对方提出请求或下达命令。

Come this way, please!

请这边走。

Don't make any noise, will you?

别吵,行吗?

Do be careful when crossing the street.

过马路时一定要小心。

(三)虚拟语气

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。

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。

I wish it were spring all the year round.

但愿四季如春。

May good luck be yours!

祝你好运!

二、条件句中的虚拟语气

英语中条件从句有两类,一类是真实条件句,另一类是非真实条件句。如果假设的情况可能发生,是真实条件句;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。

(一)真实条件句

真实条件句表示的假设是可能发生或实现的,主句和从句的谓语动词都要用陈述语气。

If he doesn't come at 8, we won't wait for him.

如果他八点不来,我们就不等他了。

If a flood happened in the past, there was usually a great loss of life and property.

过去发生洪水的话,常有很大的生命和财产损失。

We shall go there unless it rains tomorrow.

如果明天不下雨,我们将去那里。

I'll let you use my bike on condition that you keep it clean.

如果你能保持车子干净,我就让你用我的自行车。

(二)非真实条件句

在含有非真实条件句的复合句中,主句和从句的谓语动词都要用虚拟语气,其构成有三种形式:

1、表示与现在事实相反的条件

条件从句用动词的过去式(be动词用were),主句用should(第一人称)或would(全部人称) 动词原形。可用情态动词could, might代替should, would表示情态。

If it were Sunday tomorrow, I would go and see my friends.

明天要是星期天的话,我就去看望我的朋友。

If I were you, I should go and try.

我要是你,我就去试试。

If wishes were horses, beggars might ride.

如果幻想能成为马匹,叫花子都有了坐骑。

2、表示与过去事实相反的条件

条件从句用动词的过去完成时,主句用should(第一人称)或would(全部人称) have done,也可用could, might代替should, would。

If I had known your telephone number yesterday, I would have telephoned you.

如果昨天我知道你的电话号码,我就给你打电话了。

If it had not rained this morning, I should have gone shopping.

今天早上要是没下雨,我就去买东西了。

The flood might have caused great damages to the people if we had not built so many reservoirs.

倘若我们没有修建这么多的水库,洪水就会使人民遭受巨大的损失。

3、表示在将来不太可能实现的条件

表示在将来不太可能实现的条件从句有三种形式:

(1)were/did

条件从句用动词的过去式(be动词用were),主句用should(第一人称)或would(全部人称) 动词原形。也可用could, might代替should, would。

If he were here tomorrow, I would speak to him.

明天如果他在这里的话,我就和他谈谈。

If you dropped the glass, it would break.

你要是让杯子掉下来,会打碎的。

If she had time, she could help me.

她要是有时间,就会帮我了。

(2)should do

条件从句中不管什么人称都用should do,可表示有偶然实现的可能性。

If it should rain, the crops could be saved.

假如下雨,庄稼可能就有救了。

We would trust him if he should be honest.

如果他真是诚实的,那我们就相信他。

(3)were to do

条件从句用were to do。这种形式比较正式,常出现在书面语中,其假设成份很大,实现的可能性很小。

If I were to do the work, I should do it in a different way.

要是我做这项工作,我就会以不同的方式去做。

If the headmaster were to come, what would we say to him.

假如校长来了,我们对他说什么呢?

【对比】将来不太可能实现的三种非真实条件句中的虚拟语气:

常用形式:

If it snowed tomorrow, I would stay at home.

如果明天下雪的话,我就留在家里。

可能性较小:

If it should snow tomorrow, I would stay at home.

如果明天下雪的话,我就留在家里。

可能性最小:

If it were to snow tomorrow, I would stay at home.

如果明天要下雪的话,我就留在家里。

(三)省略if的条件句

在书面语中,非真实条件句中有were, had, should时,可以省略if,而把were,had, should放在主语前,用倒装结构。

Were it necessary, I might go without delay.

(= If it were necessary......)

如果需要的话,我可以立即去。

Had you taken my advice, you wouldn't have failed in the exam.

(= If you had taken my advice......)

你要是听了我的建议,就不会考试不及格了。

Should I have time, I would call on her.

(= If I should have time......)

要是有时间,我就去看她。

(四)错综条件句

虚拟条件句中的主句和从句涉及的动作发生的时间不一致,这时主句和从句的谓语形式应按照各自动作发生的实际时间来表达。

If you hadn't watched TV yesterday, you wouldn't be so sleepy now.

如果你昨天不看电视,你现在也就不会这么困了。

(从句yesterday说明过去,主句now说明现在)

If they had left home early this morning, they would arrive in half anhour.

如果他们今天一早就离开家的话,再过半小时他们就该到了。

(从句说明过去,主句说明将来。)

If you hesitated this moment, you might suffer in the future.

如果你此刻犹豫不决,你将来会吃苦头的。

(从句说明现在,主句说明将来)

【注意】在很多情况下,我们也可以用was来代替当主语是第一人称或第三人称单数时的were。

If he were here tomorrow...

也可以说成:If he was here tomorrow...

I wish I were a bird.

也可以说成:I wish I was a bird.

但倒装句型中的were不可被was来替换。

Were I in your position,I would not do it.

如果我处在你的位置,我是不会干这件事的。

(五)含蓄条件句

非真实条件句中的条件从句有时不表达出来,只暗含在上下文中,这种句子叫做含蓄条件句。含蓄条件句大体有三种情况:

1、条件暗含在短语中

He would not get such a result without your help.

没有你的帮助,他就不会有今天的成果。

(条件暗含在介词短语without your help中)

But for you, I could not be recovered so soon.

要不是有你,我就不会恢复得这么快。

(条件暗含在But for you中)

This same thing, happening in the past, would lead to a disaster. 

同样的事,如发生在过去,就会酿成大祸。

(条件暗含在分词短语happening in the past中)

He must have been there, or he never could know the place so well. 

他一定是去过那儿,否则他绝不会对那个地方如此熟悉。

(暗含条件是连词or)

2、条件可根据上下文推理出

It would do you no good.

这可能会对你没好处。

(条件可能是if you should give up the job如果你放弃这项工作的话)

They could have won. 

他们本来是会赢的。

(条件可能是if they had been patient如果他们有耐心的话)

Such mistakes could have been avoided.

这种错误完全能避免。

(条件可能是ifyou had been more careful如果你更加小心一点的话)

Why didn't you tell me about it I should have helped you.

为什么你不告诉我?我会帮助你的。

(条件可能是if you had told me about it如果你当时告诉我的话)

3、条件用其他形式来表示

She was ill, otherwise she would have been present at the meeting.

她病了,否则的话就会出席会议了。

(条件通过连词otherwiseor表示出来If shehad not been ill...)

I told him to go there himself, but perhaps I should have gone together with him.

我让他自己去那里,但也许我应该和他一道去。

(连词but暗示条件)

Suppose you were in my shoes, what would you do?

假若你站在我的立场上,你会怎么办?

(用suppose/supposing/providing等词表示if)

To talk with her, you would know she could not hear well.

如果你同她交谈,你就会知道她的听力不好。

(动词不定式带有假设的意思,相当于If you should talk with her...)

Left to himself, he could not have finished the work.

要是放任他的话,他是不可能完成工作的。

(动词的-ed形式表示条件If hehad been left to himself...)

【提示】在很多情况下,虚拟式已变成习惯说法,很难找出其暗含的条件。

You wouldn't know. 

你不会知道。

I would like to go with you. 

我愿意和你一起去。

三、虚拟语气在各种从句中的用法

虚拟语气除主要用于非真实条件句外,还可用在部分主语从句、宾语从句、表语从句、同位语从句、定语从句和状语从句之中。

(一)名词性从句中的虚拟语气

主句中的动词、名词、形容词如表示要求、建议、命令或愿望等含义,与其相关的名词性从句(主语从句、宾语从句、表语从句和同位语从句)中的谓语动词要用虚拟语气。

1、主语从句中的虚拟语气

主语从句通常用于“It is 形容词/名词/动词的-ed形式 that ...”结构。主语从句中是否用虚拟语气取决于所用的形容词或动词的-ed形式,其谓语动词常用“should 动词原形”(美国英语常省略should,只用动词原形)。

(1)表示建议或命令

It is important that we (should) work out a study plan.

重要的是我们要制订出一个学习计划。

It will be better that we (should) meet some other time.

最好我们在另一个时间见面。

It is suggested that each student (should) sing a song in English.

有人建议每个学生都要唱一首英文歌曲。

It is demanded that he should leave at once.

要求他立刻离开。

(2)表示惊讶

It is strange that he should have failed to see his own shortcomings.

真奇怪他竟看不到自己的缺点。

It is a pity shame that I should be at school instead of lying here inhospital.

真可惜,我应当在学校而不是躺在医院里。

It is natural that you should forget it first.

你起先记不住是很自然的。

【必背】常见的要接含有虚拟语气主语从句的词:

形容词:important,necessary, urgent, essential, vital, natural, strange, proper等

动词的-ed形式:arranged, suggested, ordered, required, desired,demanded,proposed等

It is necessary that the program (should) beloaded into the computer.

有必要把程序输入电脑。

It is strange that he should have learned somuch in such a short time.

很奇怪他竟然在如此短的时间内学了那么多的东西。

It is desired that we (should) get everything ready by tonight.

希望一切在今晚前准备就绪。

2、宾语从句

虚拟语气常用在表示要求、建议、命令或愿望的动词后的宾语从句中。

常见的宾语从句中需用“should 动词原形”的动词有:

一个坚持:insist

两个命令:order,command

三个建议:suggest,advise,propose

四个要求:demand,require,ask,desire

(1)在suggest(建议), order(命令), propose(建议),insist(坚持要做), command (命令),request(要求),advise(建议)等动词后的宾语从句中,谓语动词用should 动词原形(美国英语常省略should)。

The examination instructor asked that the students (should) not use a calculator.

考官要求学生不要使用计算器。

The workers demanded that their wages (should)be raised by 10 percent.

工人们要求增加百分之十的工资。

They requested that he (should) sing a song.

他们要求他唱一首歌。

【比较】动词suggest和insist后面的宾语从句,应根据不同情况选用陈述语气或虚拟语气:

A. suggest作“建议”解时,用虚拟语气,作“使想起、暗示”解时,用陈述语气。

His silence suggested that he agreed with mydecision.

他的沉默暗示他赞同我的决定。(暗示)

He suggested that I (should) stick to mydecision.

他建议我坚持自己的决定。(建议)

B. insist作“坚决要求”解时,用虚拟语气,作“坚持认为”解时,用陈述语气。

He insists that doing morning exercises does good to people's health.

他坚持认为做早操对健康有益。(强调)

He insists that he (should) do morning exercises every day.

他坚持每天都要做早操。(要求)

(2)在动词wish后的宾语从句中用虚拟语气,表示不可能实现的愿望。

①一般过去时were/did,表示目前不可能实现的愿望

I wish I were a bird.

但愿我是一只小鸟。

I wish I knew the answer.

我要是知道答案就好了。

②过去完成时had done,表示过去不可能实现的愿望

I wish she had taken my advice.

那时她要是接受我的建议就好了。

I wish that I had seen her yesterday.

③过去将来时would/could do,表示将来没有把握或不可能实现的愿望

I wish you would stay an hour longer.

我希望你再呆一个小时。

I wish it could stop raining.

但愿雨能停。

【提示】由于wish和hope的汉语意思差不多,在使用上往往容易出错。wish一般表示“希望”、“但愿”,表示不可能实现的愿望,后接从句时要用虚拟语气;hope表示“希望”,指可以实现的希望,后接从句时用陈述语气。

The students hope that their football team will win the game.

学生们希望他们的足球队获胜。(可能实现)

I wish I could see him now.

我希望现在就能看到他。(不可能实现)

3、表语从句和同位语从句中的虚拟语气

在表示建议、劝告、命令等含义的名词后的表语从句和同位语从句中,谓语动词要用“should 动词原形”结构。

3、让步状语从句

即使他失败了,仍有一线希望。

1、表示想像或猜测
