第十六章 虚拟语气

第十六章 虚拟语气

语气(Mood) 是动词的一种形式，表示说话人对某一行为或事情的看法和态度。英语有三种语气：陈述语气（Indicative Mood）、祈使语气（Imperative Mood）和虚拟语气（Subjunctive Mood）。

陈述语气用于陈述事实、描述状态，它用于陈述句、疑问句和某些感叹句。例如：

There are two sides to every question. 每个问题都有两个方面。

He has published quite a number of essays this year. 他今年已发表了好几篇论文。

Were you busy all day yesterday? 昨天一整天你都很忙吗？

How good a teacher she is! 她是多好的一位老师啊！

祈使语气用于提出请求、命令、建议或是劝告等。例如：

Wait outside until you are asked. 请在外面等候，请你进再进去。

Let’s just take a break, shall we? 我们休息一会儿，好吗？

Never be late again! 再也不要迟到了。

Don’t forget to lock the door. 别忘了锁门。

虚拟语气用于表示主观愿望和假设的虚拟情况，说话人所讲的内容往往是与事实相反的，或是其实现的可能性微乎其微，甚至于没有实现的可能性，是说话人的主观愿望、假设或推测等，有时为了使说话的语气客气、缓和、委婉。例如：

I wish you were more careful. 但愿你更细心一些。

If I were a bird, I could fly here and there in the sky. 如果我是一只鸟，我就能在天空中飞来飞去。

If I had more money, I would buy a bigger house. 我要是有再多一点钱，我就买一套更大一些房子。

May you succeed! 祝你成功！

一、虚拟语气在主语从句中的运用

有些主语从句需用虚拟语气，表示愿望、惊奇、惋惜、建议、请求、命令、理应如此等。带虚拟语气的主语从句主要有以下三种形式。

1、It＋be＋形容词＋that从句

that从句的谓语用“should＋动词原形”，或省略should直接用动词原形。常见的这类形容词有：advisable（合理的）、appropriate（合适的）、crucial（紧急的）、desirable（理想的）、essential（必要的）、fitting（合适的）、important（重要的）、incredible（惊人的）、natural（自然的）、necessary（必要的）、possible（可能的）、preferable

（更好的）、probable（可能的）、proper（适当的）、strange（奇怪的）、urgent（紧迫的）、vital（极为重要的）等。例如：

It is natural that you should say apology to him. 你自然应该向他道声歉。

It’s natural that she should do so. 她这样做是很自然的。

It is necessary that he（should）be sent there at once. 必须马上把他派到那里去。

2、It＋be＋名词＋that从句

that从句的谓语也用“should＋动词原形”，或省略should直接用动词原形。这类名词一般都表示建议、命令、请求、道歉、怀疑、惊奇等。它们有：advice（忠告）、decision（决议）、desire（愿望）、demand（要求）、idea（主意）、miracle（奇迹）、motion（提议）、order（命令）、pity（遗憾）、proposal（提议）、requirement（要求）、resolution（决心）、shame（遗憾）、suggestion（建议）、surprise（惊奇）、wish（愿望）、wonder（奇迹）等。例如：

3、It＋be＋过去分词＋that从句

二、虚拟语气在宾语从句中的运用

有些动词后跟的由that引导的宾语从句可以使用虚拟语气，这类动词有四种情况：

1、在表示提议、主张、要求、建议、命令等动词后的宾语从句中可以使用虚拟语气，

其形式是“should ＋动词原形”或省去should直接用动词原形。这类动词有：advise（建议）、ask（要求）、arrange（安排）、beg（请求）、command（命令）、decide（决定）、demand（要求）、desire（期望）、insist（坚持）、intend（打算）、maintain（主张）、object（反对）、order（命令）、pray（请求）、prefer（宁愿）、promise（允诺）、propose（提议）、recommend（推荐）、request（要求）、require（要求）、suggest（建议）、urge（催促）、vote（提议）等。例如：

有时当上述动词不是表示主张、建议或要求等，而是表示其它的意义，要用陈述语气。如当insist表示“坚持说；坚持认为”，suggest表示“暗示；说明了”等含义时，从句用陈述语气而不用虚拟语气。例如：

2、动词wish后跟由that引导的宾语从句要用虚拟语气表示一种不可实现的愿望。that从句中用过去时(be 用were的形式)表示与现在事实相反的情况，用过去完成时表示与过去相反的情况，用“would/could/might/should＋动词原形”表示将来的主观愿望。例如：

3、would rather和would sooner都表示“宁愿；宁可”的意思，它们后面的宾语从句用虚拟语气。与现在或将来事实相反时，谓语动词用过去时；与过去事实相反时，谓语动词用过去完成时。例如：

4、在think、expect、believe、mean等意念动词或态度动词后可用“should＋动词原形”或“should＋have＋过去分词”来表示惊奇，怀疑，不满等。此时，should一般不省略。例如：

三、虚拟语气在表语从句中的运用

表语从句中使用虚拟语气主要有两种情况：

1、主句谓语动词如feel（觉得）、look（看上去）、seem（似乎）等跟as if、as though引导的表语从句表达的内容属于假设情况时，要用虚拟语气。此时，表语从句用过去时表示现在情况，用过去完成时表示发过去情况，用“would＋动词原形”表示将来情况。例如：

表示实现的可能性较大时，可用陈述语气。例如：

2、一些表示建议、命令、要求等动词的同源名词如advice（忠告）、decision（决定）、demand（要求）、desire（渴望）、idea（想法）、motion（提议）、necessity（必要性）、order（命令）、plan（计划）、preference（偏爱）、proposal（建议）、recommendation（推荐）、requirement（要求）、suggestion（建议）等后面that引导的表语句往往用虚拟语气，即用“should＋动词原形”或直接用动词原形来表示。例如：

四、虚拟语气在同位语从句中的运用

六、虚拟语气在状语从句中的运用

1、虚拟语气在条件状语从句中的运用

虚拟语气表示说话者的主观愿望、假想和建议等，所说的话有的与现在事实相反，或与过去事实相反，或与将来事实相反或与将来事实可能相反。所以虚拟语气总是与非真实条件句（Unreal Conditional Sentences）用在一起。虚拟语气在条件状语从句中使用的基本特点是要设定一个条件，然后就此条件来表达想像、假设或愿望等。我们把这种表达条件的从句称为条件从句（Conditional Clause）。因为引导条件从句的最常用从属连词是if，条件从句也常叫做if条件句（if-clause）。

1）与现在事实相反

表示与现在事实相反的假设时，if条件句的结构为“If＋主语＋动词过去式＋……”，而主句的结构为“主语＋should/would/could/might＋动词原形＋……”。Should常用于表达义务、责任等，would表达意志、决心等，could表达能力、可能性等，might则表

达推想、或然性等。例如：

If he had money now, he might buy a computer. 如果他现在有钱，他或许会买台电脑。

If I had time, I would certainly join you in the tennis match. 我要是有时间肯定和你一起打这场网球比赛。

If she knew English, she would not ask me for help. 如果她懂英语的话，她不会找我帮忙的。

We would go with you if we had time. 如果我们有时间的话，就和你一道去了。

If I knew the meaning of the word, I wouldn’t have to look it up. 如果我知道这个词的意义，就不必查词典了。

If he came, he might bring his violin. 如果他来，或许会带小提琴来的。

If she were staying here now, I would let her ride my horse. 如果她现在留在这儿，我可能会让她骑我的马。

If you weren’t badly ill, you would be playing football with them on the playground. 如果你不是病重，你也会与他们一起在操场上踢球了。

如果if条件句中的谓语为be动词时，多用were。例如：

If I were very rich, I would buy you a car. 如果我是很有钱，我愿意买一辆车给你。

If I were in your place, I wouldn’t do that. 如果我是在你的立场，我不愿意做那件事。

If I were you, I’d take them away. 如果我是你的话，我就会把他们带走。

If I were you, I would put her suggestion into account. 我要是你，我会考虑她的建议的。

We could ask him if he were here. 如果他在这儿，我们就可以问他了。

If he were here, I would give him the books. 如果他在这儿，我可能会把书给他。

If places were a like, there would be little need for geographers. 如果各个地方都一样，就不需要地理学家了。

2）与过去事实相反

表示与过去的事实相反的假设时，if条件句的结构为“If＋主语＋had＋过去分词＋……”，主句的结构为“主语＋should/would/could/might＋have＋过去分词＋……”。例如：

If he had seen you yesterday, he would have asked you about it. 如果昨天他见到你，他就会问你那件事了。

If you had come earlier, you would have met him. 如果你早点儿来，就会遇到他了。

I would have called you if I had known your telephone number. 如果我知道你的电话号码，就打电话给你了。

If he had not taken my advice, he wouldn’t do it much better like this. 如果他不听取我的建议，他就不会干得这样好。

If he had followed the doctor’s advice, he would be all right now. 要是他当初听医生的劝告，他现在早没事了。

If I hadn’t been caught by something, I would have come to your party yesterday. 我昨天要不是被些事缠住了，我就会去参加你们的聚会了。

If he had been in that train then, he might have been killed 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。

If she had been at the party last night, I should have seen her. 昨天晚上她若是参加了宴会，我必定会看到她。

If you had got up earlier, you could have caught the train. 如果你早一点起床，就会赶上火车的。

If he had taken my advice, he might not have made such a bad mistake. 要是他听进了我的劝告就不会犯这么严重的错误了。

3）与将来事实可能相反

表示将来事实不可能实现的假设时，主句结构为“主语＋should/would/could/might＋动词原形＋……”，而if条件句可以是“If＋主语＋动词过去式＋……”，或“If＋主语＋should＋动词原形＋……”，或“If＋主语＋were to＋动词原形＋……”。例如：

If it were fine tomorrow, I would go shopping. 如果明天天气好，我就去买东西。

What would you do if you got a million dollars? 如果你赚了一百万美元，你会做什么？

If he came tomorrow, he would find me in the schoo1. 如果他明天来的话，会在学校找到我。

If he went tomorrow, he might tell you. 如果明天他走的话，他可能会告诉你。

If I had money tomorrow, I would buy a big color TV set. 假如我明天有钱，我会买一台大彩电。

If I should have a chance to try it, I would do it in another way. 要是我有机会试一试，我会用另一种方法做的。

If you should do that again, you might be punished. 如果你再做那样的事，你可会被处罚。

If it should rain, the crops would be saved. 如果下雨，庄稼就有救了。

If there should be another World War, what could we do? 万一再有一次世界大战，我们怎么办？

If the sun were to rise in the west, I would not believe you. 就是太阳会从西边出来，我也不会相信你的话。

If it were to snow tomorrow，they would not go out. 如果明天下雪，他们就不出去了。

If it were to rain tomorrow, I would not go for the picnic with you. 如果明天下雨，我就不和你们一同去野餐了。

If I were to pass the examination, I would treat you to dinner at KFC. 我要是过了考试，就请你去吃肯德基。

Even if they were to fail, they wouldn’t lose courage. 即使他们万一失败，他们也不会泄气。

4）混合条件（Mixed Condition）

混合条件也可称作错综时间条件，即主句和从句的谓语动词所指的时间不同。在这种情况下，动词的形式要根据实际情况灵活使用，即从句和主句根据各自发所生的时间选用符合具体时间的虚拟语气形式。例如：

If I were you, I would have gone to see the doctor. 我要是你，我早就去看病了。

You would be much better now if you had taken the doctor’s advice. 假如你当时听了医生的话，你现在就好多了。

If you had gone to see the doctor, you would be all right now. 你要早去看病，你现在就没事了。

If the boy hadn’t been saved this afternoon, his family would not be in peace now. 如果那个男孩今天下午没有被救，他的家现在就不会如此安宁。

If you had asked him yesterday, you would know what to do now. 如果你昨天问过他，今天就知道做什么了。

If it had rained last night, it would be very cold today. 如果昨晚下过雨，今天就会很冷了。

If the weather had been more favorable, the crop would be growing still better. 如果气候更适宜一些，庄稼会长得更好。

If he could pass the exam now, he would have passed it last time. 他要是现在考试及格，那他上次就及格了。

If the machine were in good conditions, we would have used it in our last experiment. 要是这台机器情况良好，我们上次就将它用于试验了。

If he were here now, he was to start off with us tomorrow. 如果他现在在这，明天他会和我们一道出发的。

If you were to visit Spain in two days, I could arrange some of my friends there to meet you at the airport. 假如你过两天去西班牙，我现在就可以安排我在那儿的朋友去机场接你。

混合虚拟语气还有一种情况就是事实和虚拟假设的混合句，这样的句子不仅仅是时间的不同，而重要是事实和假设的混合。例如：

I am very sorry if I had done anything wrong to you, but I am sure that it was unintentional. 如果我当时对你作错了什么事，我向你表示抱歉。但我敢保证我不是故意的。

Ask her to ring me up if you should see her. 你万一见到她，请让她绘我打个电话。

If you should change your mind，please let us know. 万一你改变主意，请通知我们。

If he should come, tell him to ring me up. 如果他来的话，叫他打电话给我。

Should I be free tomorrow I will come. 万一我明天有时间，我就来。

5）含蓄条件（Implied Condition）

含蓄条件句是指句中没有if条件句，其条件是通过上下文或句中内在的逻辑关系，或用其它形式表达出来的。含蓄条件句主要通过名词、连接词、不定式、分词、动名词短语、介词短语及分句来暗示。这些表达形式在句中实际起着虚拟条件从句的作用。例如：

Without air, there would be no life on the earth. 要是没有空气，地球上就不会有生命了。

Without air, we would not live even for five minutes. 没有空气，我们连五分钟都活不了。

With her help, I would do the experiment well. 假如有她帮助，我就可以把这个实验做好。

2、虚拟语气在方式状语从句中的运用

虚拟语气可用于as if或as though引起的方式状语从句中，表示“好像是这样，实际上并非如此”的含义。这时从句中的谓语动词应用虚拟语气，即谓语动词用过去时（be动词用were）表示所说的与现在的事实相反；用过去完成时表示所说的与过去的事实相反。例如：

He walks as if he were drunk. 他走路的样子好像喝醉了似的。

They treat him as if he were one of their family. 他们对待他就像他是他们的家人一样。

I’ve loved you as if you were my son. 我一直爱你就仿佛你是我的儿子。

They talked and talked as if they would never meet again. 他们谈了又谈，仿佛他们不会再相见的样子。

3、虚拟语气在目的状语从句中的运用

能用虚拟语气的目的状语从句常由特殊连词lest（以防；以免；惟恐），for fear that（免得）和in case（以防）引起，这时从句中谓语多用“（should）＋动词原形”。例如：

The old woman walked slowly lest she（should）slip. 老太太走得很慢，以免滑倒。

I wrote everything down lest I (should) forget it. 我把每件事都记下来惟恐忘记了。

He ran away lest he (should) be seen. 他跑开了，以免被人看见。

He left early in case he should miss the last train. 他动身很早以防误了最后一班火车。

in case引导的目的状语从句有时也可用陈述语气。例如：

Take warm clothes in case the weather is cold. 带些暖和的衣服，以防天气变冷。

Take an umbrella in case it rains. 带上雨伞，以防天下雨。

I spoke slowly in case they misunderstood me. 我说得很慢，以免他们听不懂。

当in case作“如果；万一”解时，常用陈述语气。例如：

I’ll be in the office all day, in case you telephone. 由于你可能来电话，我今天一天将在办公室。

In case he comes, let me know. 如果他来的话告诉我一声。

由so that和in order that引导的目的状语从句中，谓语常用“might/could＋动词原形”结构。否定式则多用“should not＋动词原形”。例如：

4、虚拟语气在其它状语从句中的运用

虚拟语气有时还可运用在原因状语从句、条件状语从句、让步状语从句等中。例如：

I’m sorry that he should be in such poor health. 他的身体这么差让我很难过。

We were surprised that she should be so foolish. 她这么傻让我们感到奇怪。

This, if the news be true, will mean a lot to us. 如果这消息是真的，那对我们来说就太重要了。

Though everyone desert you, we will not. 即使所有的人抛弃了你，我们也不会。

Whichever be the case, my situation remained the same. 无论是哪种情况，我的处境都一样。

七、虚拟语气在其它情况下的运用

虚拟语气能表示客气、委婉的意思，能给对方留有较大空间、余地，比陈述语气和祈使语气更为客气、委婉、礼貌。所以虚拟语气还可用于提出请求、发出邀请、表示祝愿或诅咒等。例如：

Could you tell me the way to the nearest shopping center? 你能告诉我去最近的购物中心的路吗？

Would you mind lowering your voice? 请你小声点儿，行吗？
