20xx年成人英语三级考试虚拟语气用法总结

在英文中表示虚拟的情况不但有虚词的提示，谓语动词也要相应的变化。

虚拟语气是英语三级考试的必考知识点之一，也是体现英汉语言习惯区别的一个语法现象。在汉语里表示假设虚拟的情况常用一些虚词来表示，例如“假设”、“如果”等，而英文中表示虚拟的情况不但有虚词的提示，谓语动词也要相应的变化。

虚拟语气的基本作用是：

(1)表达假设的情况与事实相反;(2)表达异想天开很难实现的愿望;(3)表达建议命令劝告等语气。本部分重点讲if引导的虚拟条件句，含蓄条件句、特殊结构中虚拟语气，及should+动词原形的用法。

1、虚拟语气的基本形式和用法

虚拟(条件)语气中，主句与从句中谓语动词的形式可分为下面三类：

假设类型条件从句谓语动词形式主句谓语动词形式

与现在事实相反If+动词的过去式 (be用were而不用was)would(第一人称可用should)+动词原形

与过去事实相反If+had+过去分词would(第一人称可用should)+have+过去分词

与将来事实相反If+were to+动词原形或 If+should+动词原形would(第一人称可用should)+动词原形

下面我们列举今年的真题来强化记忆。

例1 Mary said to me，“Had I seen your bag，I ____ _ it to you.”

A.will return B.must return C.could return D.would have returned

【答案】D(20xx年4月45题)

例2 I would ask George to lend us the money if I ____ _ him.

例3 If Bob ____ _ with us，he would have had a good time.

A.would come B.would have come C.had come D.came

【答案】C(19xx年59题)

1、省略if的虚拟形式

在虚拟条件句中，如谓语包含were，had，should等词，则可以把这些词放到主语前面，省略if。

例1 ____ the advice of his friends，he would not have suffered such a heavy loss in his business.

A.If he took B.If he should take C.Were he to take D.Had he taken

【答案】D(20xx年4月32题)

例2 ___ ，I should ask them some questions.

A.Should they come to us B.If they come to us C.Were they come to us D.Had they come to us

【答案】A(19xx年30题)

例3 ____ ，you were busy，I would′t have bothered you with my questions.

A.If I realized B.Had I realized C.Did I have realized that D.As I realized

【答案】B(19xx年39题)

2、含蓄条件句

有时一个假设的情况不用条件从句表示，而用其他方式来表示，这样的句子叫含蓄条件句。常用with，without，but for引导。

例1 Without heat and sunlight，plants on the earth _____ well.

A.would not grow B.will not grow C.had not grown D.would not be grown

【答案】A(20xx年11月32题)

例2 But for my classmates′help，I ____ the work in time.

A.did not finish B.could not finish C.will not finish D.would not have finished

【答案】A(20xx年11月32题)

例3 But for the rain，we _____ a nice holiday.

A.should have B.would have had C.would have D.will have had

【答案】B(20xx年4月28题)

3、特殊词或结构中的虚拟语气

(1)以wish(that)引导的表示“愿望”的宾语从句。

wish后的宾语从句中要用虚拟语气，而在虚拟语气中时态的应用类似在非真实条件中从句时态的应用。表示现在或将来的愿望用：主语+wish+从句(主语+过去时);表示一个过去没有实现的愿望用：主语+wish+从句(主语+过去完成时)。

例1 I didn′t go to the party，but I do wish I _____ there.

A.were B.would be C.had been D.will be

【答案】C(20xx年53题)

例2 Peter wishes that he ____ law instead of literature when he was in college.

A.could study B.studied C.had studied D.would study

【答案】C(20xx年53题)

(2)if only+句子(过去时/过去完成时)“要是……就好了”。

If only后面的句子如果是对现在或将来情况的虚拟，用过去时did;如果是对过去情况的虚拟，用过去完成时had done。要注意与if区别，if只表示假设，意为“如果”，用真实语气。而if only表示不可能实现的情况，用虚拟语气。

例： If only the alarm clock had rung.当时闹钟响就好了。(对过去虚拟)

If only I were rich.要是我富有就好了。(对现在虚拟)

(3)would rather+句子(过去时)。

表示宁愿、宁可的意愿，语气比较婉转，后接过去式。

例1 I am too busy these days. I would rather all of you ____ next month for a dinner.

A.come B.would come C.came D.have come

【答案】C(20xx年46题)

例2 I′d ____ you didn′touch that，if you don′t mind. A.rather B.better C.happier D.further

【答案】A(19xx年45题)

(4)it is time (that)，it is high time(that)…句型中，谓语动词用过去时，表示早该做而未做的事，意思是“该……了、早该……了”。

例1 Let′s finish our homework in a faw seconds;it′s time we ____ _ .

A.played football B.will play football C.play football D.are playing football

【答案】A(20xx年11月43题)

例2 Don′t you think it is time you _ _ smoking?

A.give up B.gave up C.would give up D.should give up

【答案】B(19xx年31题)

(5)以as if，as though引导的从句。

在as if，as though引导的从句中，如果谈论的是不可能或不真实的情况时，他们所引导的状语从句要用虚拟语气，动词形式和wish后面的从句动词形式变化相同。

例：He talks as he ___ everything in the world.

A.konws B.knew C.had known D.would have known

【答案】B 本句表示说话人对现在的情况有所怀疑，所以用过去的。

4、should +动词原形及should的省略

(1)一些表示建议、要求、命令等的动词本身隐含说话者主观的意见。因此这些动词(或其派生词，如名词、形容词、分词等)后面的从句应使用虚拟语气，即“should do”结构，其中的“should”常被省略。如：

表示“提议、建议”的动词：suggest，advise，propose，recommend，move(提议); 表示“要求、主张”的动词：insist，require，request，demand，desire;

表示：“命令”的动词：order，command。

例1 I don′t think it advisable that Tom _____ to she job since he has no experience.

A.be assigned B.is assigned C.will be assigned D.has been assigned

【答案】A(20xx年11月29题)

例2 His mother insisted that he _____ the coat when going out.

A.put on B.puts on C.to put D.putting on

【答案】A(19xx年58题) 此处省略了should。

例3 The doctor advised that Mr.Malan ____ an operation right away so as to save his life.

A.had B.would have C.have D.was going to have

【答案】C(19xx年28题) 此处省略了should。

(2)It is necessary/important/essential/vital/urgent/surprising/amazing that…引导的主语从句中，从句的谓语动词要用should + 原形动词，should也可以省略。此类形容词的特点是表示重要性或吃惊。

例1 It is vital that enough money _____ collected to get the project started.

A.is B.be C.must be D.can be

【答案】B(20xx年11月24题)

例2 It′s urgent that a meeting _____ befor the final decision is made.

A.will be arranged B.must be arranged C.be arranged D.would be arranged

【答案】C(20xx年4月45题)

(3)以in case，lest，for fear that 引导的状语从句，表示“以防、以免”其形式为should+动词原形。

He took his raincoat with him in case it should rain. 他把雨衣带在身上

第二篇：英语中虚拟语气的用法有哪些？

一、虚拟现在(Subjunctive Present):

虚拟现在的句子，在任何时候都要用动词的原形(root form)，就算是第三人称(he,

she, it)也是如此。如：

1.1 现在时态(Simple Present): (右边为虚拟语气)

I work ---- I work

you work ---- you work

he works ---- he work (注意到了吗，是 work，不是 works) she works ---- she work (不是 she works 喔）

it works ---- it work (同样不是 it works 喔)

we work ---- we work

they work ---- they work

1.2 现在进行时态(Present Continuous):(右边为虚拟语气）

I am working ---- I be working (注意用的是 be，怪怪的!) you are working ---- you be working

he is working ---- he be working

1

she is working ---- she be working

it is working ---- it be working

we are working ---- we be working

they are woring ---- they be working

1.3 现在完成时态(Present Perfect):(右边为虚拟语气)

嘘，暂时休息一会儿。下回再谈虚拟过去的动词有什么不同。如何，你喜欢她吗？

谈谈虚拟语气(Subjunctive Mood)（二）

二、虚拟过去(Subjunctive Past)

虚拟过去的动词无论在什么情况之下都要用过去复数形式。如：动词 be，在虚拟过去

I worked ---- I worked

you worked ---- you worked

he worked ---- he worked

she worked ---- she worked

3

it worked ---- it worked

we worked ---- we worked

they worked ---- they worked

2.2 过去进行时态(Past Continuous):(右边为虚拟语气)

2.3 过去完成时态(Past Perfect):(右边为虚拟语气)

I had worked ---- I had worked

you had worked ---- you had worked

谈谈虚拟语气(Subjunctive Mood)（三）

虚拟语气在语法里算得上是个难点。让我们就从最简单的开始吧。

三、简单的祝愿和命令：

1. May you be happy. (注意那个 be ) 祝你幸福。

2. May you have a good time.

3. May the friendship between us last long,

4. Have a good journey! 祝你旅途愉快！

3.2 命令

注意：1.命令虚拟语气只能用在第二人称(you)，而且通常省略主语(也就是you)。

2.句子尾通常加上感叹号：！

谈谈虚拟语气(Subjunctive Mood)(七)

八、虚拟语气在条件从句(Protasis)中的用法：

条件从句有两类：（1）真实条件句；（2）虚拟条件句。

如果假设情况有可能发生的，就是"真实条件句"。如：

1. If time permits, we'll go fishing together.

(如果有时间的话，我们就一起去钓鱼。）

15

如果假设的情况与事实相反，则为"虚拟条件句"。如：

1. If it had rained yesterday, we would have stayed at home.

（如果昨天下雨的话，我们就会留在家里。）

这回我们要谈的就是关于"虚拟条件句"的一些句型。

* 这种句子一般由"从句"（Subordinate Clause)和"主句"(Main Clause)组成。如上

例：

If it had rained yesterday, we would have stayed at home.

"If it had rained yesterday" 就是"从句"；"we would have stayed at home" 则

为"主句。

* 无论"从句"或"主句"的谓语都要用虚拟语气。它们所用的动词有三种时态

(Tenses)，就是：

现在时态、过去时态、将来时态。

* 句型：

8.1 与现在事实相反的假设(事情的发生都在同一时间内):

16

从句：if + 主语 + 动词的过去式(be 用 were) + ……

主句：主语 + would (should, could , might) + 动词原形 + ……

1. If I were you, I would go with him.

(从句 If I were you, 主句 I would go with him.)

2. If I were you, I should buy it.

(从句用过去式动词were，主句用动词原形 buy)

3. If I had time, I would study French. (如果有时间，我会学习法文。） （从句用过去式动词had，主句用动词原形 study）

4. If she knew English, she would not ask me for help. (如果她懂英文，她就

不必要我帮了。)

(从句用过去式动词knew, 主句用动词原形ask)

注意：如果动作在进行中，主句要用："主语 + would be + 进行式动词 + ……"

5. If they were here, he would be speaking to them now.

(从句用过去式动词were, 主句用 would be speaking)

17

8.2 与过去事实相反的假设(假设从句的事实为过去的事)：

从句：If + 主语 + had +过去完成式动词 + ……

主句：主语 + would (should, could, might) + have +过去完成式动词 +……

1. If you had studied harder last term, you could have passed exam. (从句动词用had studied, 主句动词用have passed)

如果你在上个学期用功一些，你就会在考试中过关了。

2. If you had taken my advice, you wouldn't have failed in the exam. (从句动词用had taken, 主句动词用have failed)

如果下雪的话，我就可在公园里滑雪了。

18

注意：如果动作在进行中，主句要用："I主语 + would + have + 完成进行式动词

+……

5. If they had been here, he would have been speaking to them. (从句动词用had been, 主句动词用 have been speaking)

8.3 与将来的事实可能相反(对将来的事实实现的可能性不大)：

从句：If + 主语 + should (或were) + 动词原形 +……

主句：主语 + would (could, should, might) + 动词原形 +……

1. If it should rain, the crops would be saved.

(从句动词用should rain，主句动词用 be)

如果天下雨，庄稼可能就收获了。

2. If he were to go fomorrow, he might tell you.

(从句动词用were to, 主句动词用 tell)

如果明天他走的话，他可能会告诉你。

19

3. If he were here, I would give him the books.

(从句动词用 were, 主句动词用 give)

如果他在这儿，我可能会把书给他。

注意：如果动作在进行中，从句(不是主句喔)要用："If + 主语 + 过去进行式动词

+……"

4. If she were staying here now, I would let her ride my horse. (从句动词用 were staying, 主句动词用 let)

如果她现在留在这儿，我可能会让她骑我的马。

8.4 从句的 If 有时可省略，那么从句中的动词(were, had, should)就得移到主语前

面：

1. 原句：If she were younger, she would do it.

去If：Were she younger, she would do it. (把动词were移到主语she的前面)

2. 原句：If he had tried it, he could have done it.

20

去If：Had he tried it, he could have done it.(把had移到主语he的前面)

8.5 有时虚拟条件句的从句或主句都可以省略其中一个：

1. I could help you. (只有主句）

2. If I had time. (只有从句）

3. She should have come to the meeting. (只有主句)

4. If he had much more money. (只有从句)

8.6 有时虚拟条件句的从句和主句地动词动作时态会不一致：

8.6.1 从句表示过去，主句表示将来：

If they had started the early morning yesterday, they would be here now.

8.6.2 从句表示将来，主句表示过去：

If I were not to make a preparation for my experiment this afternoon, I 21

would have gone to see the film with you last night.

8.6.3 从句表示过去，主句表示将来：

If we hadn't made adequate preparations, we shouldn't dare to do the experiment next week.

8.6.4 从句表示将来，主句表示现在：

(would + 原形动词meet，表示与将来事实相反)
