状语从句
（Adverbial Clause）

一 状语从句的种类

§ 1状语从句的种类

用来修饰谓语动词、其它动词、定语、状语或整个句子的从句叫做状语从句。状语从句可分为：

1.时间状语从句；(adverbial clause of time)

2.地点状语从句；(adverbial clause of place)

3.原因状语从句；(adverbial clause of cause)

4.条件状语从句；(adverbial clause of condition)

5.目的状语从句；(adverbial clause of purpose)

6.让步状语从句；(adverbial clause of concession)

7.比较状语从句；(adverbial clause of comparison)

8.程度状语从句；(adverbial clause of degree)

9.方式状语从句；(adverbial clause of manner)

10.结果状语从句。(adverbial clause of result)

§2状语从句的时态特点

一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如：

I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive）

As soon as I have finished this work, I will go home. 我一完成此工作，就回家。（从句中的谓语动词用现在完成时have finished，表示将来完成时,决不可用will have finished）

If he comes back, please let me know.如果他回来了，请通知我。（从句中的谓语动词用comes back,表示一般将来时，决不可用will come back）

二 时间状语从句

§3时间状语从句（adverbial clause of time）

1.由when, while, as引导的时间状语从句。例如：

When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。

When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！

Strike while the iron is hot. 趁热打铁。

Will you watch my clothes while I have a swim. 我游泳的时候，请你照看一下我的衣服。

You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。

Our headmaster laughed as she spoke.我们的校长边谈边笑。

【区别】when, while和as的区别：when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。例如：

When she came in, I stopped eating.她进来时，我在吃饭。(瞬时动词)

When I lived in the countryside, I used to carry some water for him.当的住在农村时，我常常为他担水。（延续性的动词）

We were about to leave when he came in.我们就要离开，就在那时他进来了。

While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如：

While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生)

I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比）

As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。例如：

We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）

As we was going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）

2.由before和after引导的时间状语从句。注意before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。还要注意主句和从句之间的时间关系。当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和从句的动作的时间关系正好与before引导的从句相反。例如：

It will be four days before they come back. 他们要过四天才能回来。

Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我。

My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了。

They had not been married four months before they were divorced. 他们结婚还不到四个月就离婚了。

After you think it over, please let me know what you decide.你仔细考虑过以后，告诉我你是怎样决定的。

After we had finished the work, we went home.完成工作之后，我们回家了。（从句用过去完成时，主句用一般过去时）

3.由till或until引导的时间状语从句。till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。例如：

I didn't go to bed until（till） my father came back.直到我父亲回来我才上床睡觉。

It was not until the meeting was over that he began to teach me English.直到散会之后他才开始教我英语。

I worked until he came back.我工作到他回来为止。

I didn't work until he came back.他回来我这才开始工作。

Please wait until I arrived.在我到达之前请等我。

4.由since引导的时间状语从句。 since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。但在It is ＋时间＋since从句的句型中，主句多用一般现在时。例如：

I have been in Beijing since you left. 自从你离开以来，我一直在北京了。

Where have you been since I last saw you? 自上次我和你见面以后，你到哪里去了？

It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。

It is five months since our boss was in Beijing.我们老板离开北京有五个月了。

5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。这些连词都表示“一……就”。例如：

I will go there directly I have finished my breakfast. 吃完早饭，我立即到那里去。

The moment I heard the news, I hastened to the spot.我一听到消息，马上赶到了出事地点。

As soon as I reach Canada, I will ring you up. 我一到加拿大，就给你来电话。

【注意】hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as之意。主句用过去完成时，从句用一般过去时。当hardly, scarcely, rarely和no sooner位于句首时，主句应用倒装语序。例如：

He had no sooner arrived home than he was asked to start on another journey. 他刚到家，就被邀请开始另一旅程。

No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太阳刚从地平线上升起，他就起床劳动去了。

Hardly had I sat down when he stepped in.我刚坐下，他就进来了。

He had hardly fallen asleep when he felt a soft touch on his shoulder.这个阿拉伯人刚要入睡就感到肩膀上被轻轻一触。

6.由by the time引导的时间状语从句。注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时；如果主句的谓语动词用一般现在时，主句的谓语动词用将来完成时。例如：

By the time you came back, I had finished this book.到你回来时，我已经写完这本书了。

By the time you come here tomorrow, I will have finished this work. 你明天来这儿的时候，我将已经完成此工作了。

7.由each time, every time和whenever引导的时间状语从句。例如：

Each time he came to Harbin, he would call on me. 他每次来哈尔滨，总是来看我。

Whenever that man says“To tell the truth”, I suspect that he's about to tell a lie.每当那个人说“说实在话”的时候，我猜想他就要说谎了。

You grow younger every time I see you. 每次遇到你，见你更年轻了。

8.由as long as和so long as引导的时间状语从句。这两个连词表示“有多久……就多久”。例如：

You can go where you like as long as you get back before dark. 你可以随意到哪里去，只要在天黑以前回来就行。

I will fight against these conditions as long as there is a breath in my body! 只要我一息尚存，我就要反对这种境况。

三 地点状语从句

§4地点状语从句 (adverbial clause of place)

地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，例如：

句型1：Where＋地点从句，（there）＋主句。

【注意】此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如：

Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。

They were good persons. Where they went, there they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。

You should have put the book where you found it. 你本来应该把书放回原来的地方。

Where the Communist Party of China goes, there the people are liberated.哪里有了中国共产党，哪里人民得解放。

句型2：Anywhere/ wherever＋地点从句，＋主句。

【注意】anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere引导的从句可位于主句之前，也可以位于主句之后。 而wherever本身就是个连词，表示“在何处，无论何处”。例如：

Wherever the sea is , you will find seam
呵呵……

虚拟语气
虚拟语气是通过特殊的谓语动词形式来表达的愿望、假设、怀疑、猜测或建议等语气，它不表示客观存在。
一、 虚拟语气在单句中的用法
常用来表示祝愿、采用固定的倒装句式。例如：
Long live the People´s Republic of China!中华人民共和国万岁！
be happy! 快乐！
have a good time! 玩得愉快！
succeed! 成功！
make progress! 进步！

二、虚拟语气在复合句中的用法：
1． 在非真实性条件句与主句中的用法
1） 表示与现在事实相反
条件从句 主句
一般过去时（be多用于were） would/should/could/might＋动词原形
例如：If I were you,I should accept the invitation.
如果我是你，我会接受邀请的。
If I had time,I would go there.
如果我有空，我就去那儿。

2） 与过去事实相反
条件从句 主句
过去完成时 would/should/could/might＋have done
例如：If you had come earlier,you couldn´t/wouldn´t have missed the bus.
如果你早点来，你就不会错过那辆公共汽车了。
If he had seen you yesterday,he would have returned your book.
如果他昨天见到了你，他就会还你的书的。

3） 与将来事实可能相反
条件从句 主句
一般过去时（be多用were）should do,were to do would/should/could/might＋动词原形

例如：If it should rain/were to rain/rained tomorrow,the sports meet would be
put off.万一明天下雨，运动会就推迟。（事实上明天下雨的可能性不大。）
If you dropped/should drop/were to drop the glass,it would break.
万一杯子掉下来会打碎的。

4） if的省略
如果条件句中有were,had,should 等助动词，可将if省略，而把were,had或should
置于句首,来表达以if引导的条件句的相同意思。
例如：Should it rain/were it to rain tomorrow,the sports meet would be put off./Had he seen you yesterday,he would have returned your book.

5)条件句或主句的省略
当有上下文或上下句中的语言环境暗示的时候，表示虚拟语气的从句或主句往往可以省略，以避免重复。
例如：——Why didn´t you attend the party yesterday?
——I would/should have,but I was too busy then.
I was surprised that you didn´t like this job.You could have done it better.（后面省略了if you had liked it.）

6)混合时间条件句与主句
条件句与主句的动作发生的时间有先后之差，应按各自动作时间搭配好相应的结构形式。
例如：If the teacher hadn´t been ill yesterday,who could give us a lecture now?/If you had reviewed the lesson,you would answer the question now.

7)含蓄条件句与主句
即用without(＝but for),or(else)代替if从句。
例如：Without/But for his help,we wouldn´t have made such great progress.

＝If his help,we wouldn´t have made such great progress.

2.在as if/as though引导的状语从句中用法：
在as if/as though引导的状语从句中，谓语动词多用倒退一个时间段的方式来表达虚拟语气。例如：
The man speaks as if he were a foreigner./The speaker told us a lot about that country as though he had been there many times./They talked as if they had been good friends for years.

注：as if/as though从句中不一定都要用虚拟语气。如果情况真实性、可能性很大，就要用正常时态来描绘。例如：It looks as if it is going to rain.天看起来象要下雨。（下雨的可能性很大。）

3．在宾语从句、表语从句、主语从句中的用法：
1） 在wish后的宾语从句中的用法：
A．与过去事实相反的愿望：宾从谓语为“had done”形式。例如：I wish I had passed yesterday´s exam.要是我昨天的考试及格了该多好。
B．与现在事实相反的愿望：宾从谓语为“did”形式。例如：He wishes he was as clever as you./I wish I had a large room to live in.
C．表示将来愿望：宾从谓语用“would/could do”形式。例如：How I wish I would go abroad next year!

2)在suggest,propose,demand,request,require,order,insist等动词后的宾语从句中，谓语为“(should) do”形式。例如：I suggest/propose/demand/request/require/order/
insist that he(should) be sent to the nearest hospital as soon as possible.

3)在“It is (about/high) time＋that从句”结构中，that从句的谓语用一般过去

时或“should do”形式。例如：It is high time he 他该开始了。

4)在表语从句、同位语从句中的用法：在suggestion,proposal,request,requirement,
advice等名词后的表语从句、同位语从句中，谓语用“(should) do”形式。例如：
My suggestion is that we (should) send a few comrades to help the other groups./He gave an order that the work be done at once.

虚拟语气考点分析
1．——Alice,why didn´t you come yesterday?
——I _____,but I had an unexpected visitor. (NMET)
A.had B.would C.was going to D.did
析:此题A、D明显不合上下文，因为乙方没有去。B选项若为would have则成立，可以理解为I would have come if I hadn´t had an unexpected visitor.的简略式。但此处是would,故应排除。只有was going to可得体地表达“我原本打算去的，但是有不速之客造访”这一意思。
2．If there were no subjunctive,English ______ much easier. (NMET)
A.will be B.would have been C.could have been D.would be
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。
3．The guard at the gate insisted that everybody ______ the rules. (NMET)
A.obeys B.obey C.will obey D.would obey
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。
4．I wish I _____ you yesterday.
A.seen B.did see C.had seen D.were to see
析：此题表与过去事实相反的原望，答案应为C。
5．—— If he _____ ,he _____ that food.
—— Luckily he was sent to the hospital immediately. (NMET)
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
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。
6.Without electricity human life _____ quite different today. (NMET)
A.is B.will be C.would have been D.would be
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。
7．When a pencil is partly in a glass of water,it look as if it _____. (NMET)
A.breaks B.has broken C.were broken D.had been broken
析；放入水中的铅笔看上去是断的，但实际上并非如此，因此是与现在的事实相反，这时as if从句谓语要用一般过去时，故答案为C。
8．You didn´t let me drive.If we _____ in turn,you _____ so tired. (NMET)
A.drove;didn´t get B.drove;wouldn´t get
C.were driving;wouldn´t get D.had driven;wouldn´t have got
析：观察题干，可知if从句表述与过去事实相反的假设，因此答案只能是D。
9．I didn´t see your uncle at the party.If he _____ ,he would have said hello to
me.
A.would come B.had come C.came D.did come
析：观察题目上下文，特别是第二句的主句谓语为 would have said，可知if从句表述的是与过去事实相反的愿望，因此答案为B。
10．_____ it _____ for your help,I couldn´t have made any progress.
A.Had;not been B.Should;not be C.Did;not be D.Not;be
析：根据主句谓语形式，可知从句要用had done形式，故应选A，Had it not been for your help＝If it had not been for your help.（要不是你帮忙的话）
11．Mr Smith was badly ill,or he _____ our dinner party.
A.should come to B.would have attended
C.would come to D.should have attended
析：or可引导含蓄条件句，表达虚拟语气。根据此题内容，可知是与过去事实相反的假设，故答案为B。
