状语从句讲解
状语从句大盘点作者/李 静
状语从句一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。要想掌握它关键是要掌握引导不同状语从句的常用连接词。现分别列举如下：
【小结1】
常见的时间状语从句的引导词有：when（当……的时候），whenever（每当），after（在……之后），before（在……之前），as（当……；一边……一边），as soon as/hardly…when/no sooner…than（一……就……），while（在……期间），till/until（直到），since（自从）等。
1.He was reading newspapers as he was waiting for the bus.
他一边等公共汽车，一边读报纸。
2.He has taught English in this middle school since he graduated from college.
自从大学毕业，他就在这所中学教书。
3.I’ll give you a phone as soon as I come back.我一回来就给你打电话。
注意：
1.当since引导状语从句，主句往往用现在完成时态，如例2。
2.如果主句是一般将来时态，从句用一般现在时态，如例3。
【小结2】常见的条件状语从句的引导词有：
1.由if，unless引导，if意为“如果”，unless意为“除非，如果不”（if not）。
You will be late unless you leave immediately.除非你立即走，否则，你会迟到。
If you don’t hurry up，you’ll be late.如果你不快点，你就会晚了。
2.由suppose，supposing，as/so long as，providing，provided，on condition that和in case等引导。这类连词（词组）意思相近，有“如果、假设、即使、在……条件下”等意义。
Suppose （Supposing） he is ill，what shall we do？如果他病了，我们该怎么办？
You’ll succeed，as long as you follow his advice.只要你听从他的劝告，你就会成功的。
注意：
在条件状语从句中，当主句和从句动作都表示将来时，主句用将来时态，从句用一般现在时态。
【小结3】常见的原因状语从句的引导词有：because（因为），since（既然），as（由于），now that（既然，因为）等连词引导：
1.because
表示直接的原因或理由，表示原因的语气最强，常表示必然的因果关系。回答以why引起的特殊疑问句，只能用because。
Jane wore a raincoat because it was raining.因为天下雨，所以简穿着雨衣。
He is absent today because he is ill.他今天缺课，因为他病了。
2.since
表示对方已经知晓、无须加以说明的原因或事实，语气比because稍弱。
I’ll do it for you since you are busy.既然你忙，我来替你做吧。
Since you insist，I’ll go.既然你坚持，那我就去。
3.as
表示的往往是十分明显的原因，听者或读者已经知道或能看得出来，语气较弱，只附带说明，比较口语化。
We had better hurry as it’s getting dark.因为天快要黑了，我们最好快点。
As it is raining，I’ll not go out.因为正在下雨，我就不出去了。
4.for
for是并列连词，它引导的分句不表示直接的原因，而是用来附带解释或说明前面一句的情况。for引导的分句常位于第一分句之后，它们之间用逗号隔开。
It must have rained last night，for the ground is wet this morning.昨晚准是下雨了，今天早上地面还是湿的。
The day breaks，for the birds are singing.小鸟在歌唱，一定是天亮了。
5.now that
意为“既然”，与since同义，但更突出事实本身。
Now that you’ve got a chance，you might as well make full use of it.
既然你有了机会，你要充分利用它。
Now that everyone is here，let’s begin our meeting.既然大家都来了，我们就开始开会吧。
【小结4】常见的地点状语从句的引导词有：(www.fwsir.Com)where（在……地方； 那里），wherever（无论哪里）引导。
You should make it a rule to leave things where you can find them again.
你应当养成惯例，将东西放在你能找到的地方。
Sit wherever you like.请随便坐。
Wherever you go，you must remember you are a Chinese.无论走到哪里，都要记住自己是中国人。
【小结5】常见的让步状语从句的引导词有：though，although，as，even if （though），however，whatever，whoever，whenever，no matter +wh词等。
1.even if，even though，although，though引导的让步状语从句
这四个词（词组）都有“虽然、即使、尽管”的意思。even if和even though带有较强的意味，语气比although和though强。though不如although正式，都不能和but连用，但可以和yet，still或nevertheless连用。
Although he is considered a great writer，his works are not widely read.
虽然有人认为他是一个大作家，但是他的作品读得并不广泛。
We won’t give up even if we should fail ten times.即使失败十次，我们也不会放弃。
2.as或though引导让步状语从句
形容词+as/though+主语+动词
副词+as/though+主语+谓语
动词+as/though+主语+情态动词/助动词
名词+as/though+主语+动词
1）由as或though引导让步状语从句往往会前置表语、谓语动词原形及修饰动词的副词
Much as I admire his courage，I don’t think he acted wisely.
我虽然佩服他的勇气，但是我认为他这样做是不明智的。
Young man as he is，he has made great achievements in the field of IT.
尽管他很年轻，却在IT领域取得很大成就。
Try as I might，I couldn’t lift the stone.我使多大劲儿也搬不动这块石头。
2）如果表语为单数可数名词，这个名词不带冠词
Child as he is，he knows a lot.虽然他还是个孩子，却懂的很多。
3.由no matter+wh词和由疑问词+ever引导让步状语从句
由no matter引导，表示“不管，无论”；由疑问词+ever引导，表示“不管，不论”。这类词有：whatever，whichever，whoever，however，whenever，wherever等，它们相当于no matter+ what（which，who，how，when，where），都不能与but，so，and等并列连词同时使用。
We’ll have to finish the job，however（no matter how） long it takes.不管需要多长时间，我们都一定要完成这项工作。
No matter what（Whatever） you do，don’t tell him that I told you this.无论你做什么，别告诉他我对你说过这件事。
No matter where （Wherever） you go，I would keep you company.不管你到哪去，我都会陪着你。
4.由whether…or引导让步状语从句
由whether…or引导让步状语从句表示“不论……还是”，提供两种对比的情况。
I shall go，whether you come with me or stay at home.
不论你和我一起来还是留在家中，我都要前往。
【小结6】方式状语从句一般由as（正如；按照），as if/as though（好像）等引导。
When in Rome，do as the Romans do.入乡随俗。
You must do everything as I do.你们要照我这样去做。
注意：As if/as though 引导方式状语从句时，从句的语气如果符合真实情况，则用陈述语气，如果与真实情况不符，则用虚拟语气，从句谓语时态在原来的基础上退后一步。例如：
He walked slowly as if he had hurt his leg.他走得很慢，好像腿受了伤。
She speaks English as if she were a native speaker.她讲英语俨然像专家。
【小结7】常见的结果状语从句的引导词有：so…that，such…that，so that…等。例如：
He worked hard so that he passed the exam.他学习很努力，结果通过了考试。
The film was so wonderful that we wanted to see it again.电影很精彩使我们还想看一次。
He spoke for such a long time that people began to fall asleep.
他讲了那么长时间，人们开始打起瞌睡了。
注意：so…that与such…that的区别
这两种结构都可引导结果状语从句。so是副词，后接形容词或副词；such是形容词，后接名词。
（1）单数名词
在so…that与such…that中间出现的'是单数名词，且该名词前有形容词修饰时，这两种结构可互换，但要注意它们的词序不同：such+a/an+形容词十名词=so+形容词+a/an+名词。
She is such a good teacher that all of us love her.=She is so good a teacher that all of us love her。
她是一位很好的老师，我们都敬爱她。
（2）不可数名词或复数可数名词
如果被修饰的是不可数名词或复数可数名词时，一般须用such…that。但如果不可数名词或复数可数名词前有many，much，little，few修饰时，则用so…that。
He made such rapid progress that before long he began to write articles in English.
他进步很快，不久就开始用英语写文章。
They are such interesting books that we all want to read them.
这些书是那么有趣使我们都想读一读。
I’ve had so many falls that I’m black and blue all over.我摔了好多次跤，全身青一块紫一块的。
George had so little money that he had to get a job.乔治没有钱，所以他不得不找工作干。
【小结8】常见的目的状语从句的引导词有：so that…，in order that…等。从句中的谓语动词前常有情态动词may，might，can，could，will，would等。
John shut everybody out of the kitchen so that he could prepare his grand surprise for the party.
约翰把其他人关在厨房外，目的是能够为晚会烹饪出人意料的东西。
These men risk their lives in order that we may live more safely.
这些人甘冒生命危险，是为了让我们活得更安全些。
Drive carefully so that everyone can enjoy a long life.开车小心点，让大家多活几年。
注意：
in order that引导的状语从句可以放在句首与句尾，而so that 引导的只能放在句尾。
【小结9】比较状语从句一般由as…as（和……一样），not as/so…as（与……不一样），than（比）引导。
The director gave me a better offer than he gave Dick.导师给我的提议比给狄克的好。
John plays football as well as，if not better than，David.
如果说约翰的足球踢得不比大卫好，至少和他踢得一样好。
I can’t run as/so fast as he can.我不能跑得他那样快。
篇3：初中英语状语从句用法
1 时间状语从句
(1)时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。例如：
It was raining hard when got to school yesterday.
While he was doing his homework, the telephone rang.
As he walked along the lake, he sang happily.
He had learned a little Chinese before he came to China.
After he finished middle school, he went to work in a factory.
(2)在时间状语从句里，通常不用将来时态，用现在时态表示将来的动作或状态。例如：
I’ll ring you up as soon as I get to New York.
I will tell him everything when he comes back.
He won’t believe it until he sees it with his own eyes.
(3)在带有till或until引导的时间状语从句的主从复合句里，如果主句用肯定式，其含义是“一直到……时”，谓语动词只能用延续性动词。如果主句用否定式，其含义是“直到……才……”, “在……以前不……”, 谓语动词可用瞬间动词。例如：
The young man read till the light went out.
Let’s wait until the rain stops.
We won’t start until Bob comes.
Don’t get off until the bus stops.
2 条件状语从句
(1)条件状语从句通常由if, unless引导。例如：
What shall we do if it snows tomorrow?
Don’t leave the building unless I tell you to.
(2)在条件状语从句里，谓语动词通常用现在时态表示将来的动作或状态。例如：
I’ll help you with your English if am free tomorrow.
He won’t be late unless he is ill.
(3)“祈使句 + and (or)+ 陈述句” 在意思上相当于一个带有条件状语从句的复合句。例如：
Hurry up, or you’ll be late.
=If you don’t hurry up, you’ll be late.
Study hard and you will pass the exam.
=If you study hard, you will pass the exam.
3 原因状语从句
(1)原因状语从句通常由because, since, as引导。例如：
He didn’t come to school because he was ill.
As it is raining, we shall not go the zoo.
Since you can’t answer the question, I’ll ask someone else.
(2)because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。As和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。例如：
------Why aren’t going there?
------Because I don’t want to.
As he has no car, he can’t get there easily.
Since we have no money, we can’t buy it.
(3)because和so不能同用在一个句子里。
4 结果状语从句
(1)结果状语从句由so…that, such…that, so that引导。例如：
He is so poor that he can’t buy a bike for his son.
She is such a good teacher that everybody likes her.
My pencil fell under the desk, so that I couldn’t see it.
(2)so…that语such...that可以互换。例如：
在由so...that引导的结果状语从句中，so是副词，与形容词连用。其结构是: “...so + 形容词(副词)+ that + 从句”。例如：
He was so glad that he couldn’t say a word.
The hall is so big that it can hold 2,000 people.
Mother lives so far away that we hardly ever see her.
在由such…that引导的结果状语从句中，such是形容词，它修饰的可以是单数或复数可数名词，也可以是不可数名词;名词前面可以带形容词，也可不带。如果是单数可数名词，前面需加不定冠词a或an。例如：
It was such a hot day that nobody wanted to do anything.
He had such long arms that he could almost touch the ceiling.
He made such rapid progress that he did very well in the mid-term.
有时上述两种结构是可以互换的。例如：
It was such a wonderful film that all of us wanted to see it again.
=The film was so wonderful that all of us wanted to see it again.
It is such an important match that nobody wants to miss it.
=The match is so important that nobody wants to miss it.
(3)如果名词前由many, much, little, few等词修饰时，只能用so, 不用such。例如：
Soon there were so many deer that they ate up all the wild roses.
He has so little time that he can’t go to the cinema with you.
5 比较状语从句
比较状语从句通常由as…as, 比较级 + than…等连词引导。例如：
Tom runs faster than John does.
This classroom is as big as that one.

(1)目的状语从句通常由 so that, in order that引导。例如：
We started early so that we could catch the first train.
He studies hard so that he could work better in the future.
We used the computer in order that we might save time.
(2)so that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, could, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：
Speak clearly so that they may understand you. (目的状语从句)
Jack is badly ill so that he has to rest. (结果状语从句)
7 让步状语从句
(1)让步状语从句通常由although, though等连词引导。例如：
Though he is young, he knows a lot.
Although I am tired, I must go on working.
(2)although(though)不能用在同一个句子中。例如：
我们不能说：Though it was raining hard, but he still went out.
应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out.
8 地点状语从句
地点状语从句常常由where来引导。例如：
Go where you like.
Where there is a will, there is a way.
延伸阅读：
1.初中状语从句常见考法
对于结果状语从句的考查，多以单选和完形填空的形式，从连词的意义角度让大家选择连词。
典型例题：
His plan was such a good one ____ we all agreed to accept it.
A. so B. and C. that D. as
解析：题干的意思是“他的计划如此好以至于我们都同意接受它”，that与前面的such呼应， 引导结果状语从句。
答案：A
2.初中状语从句误区提醒
结果状语从句中。除了要注意so… that和 such…that的区别外，还要注意它们和too...to do(太・・・而不能・・・・)和enough +形容词/副词+to do(足够的・・・可以・・・)的转换。
典型例题：
Ann is too young to go to school.(同义句转换)
Ann is go to school.
解析：原句的意思是“安太小了而不能去上学”。那也就是说“安是如此的小，以至于她不能去上学”，根据所给出的空数，可以用so… that句型.
答案：so young that she can't
篇4：高考状语从句用法
(一)时间状语从句
表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。
e.g. When I came into the office, the teachers were having a meeting.
He started as soon as he received the news.
Once you see him, you will never forget him.
No sooner had I gone to bed than I went to sleep.
(二)原因状语从句
原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that(既然)等，for 表示因果关系时(它引导的不是从句)为并列连词，语气不如because强。
e.g. He is disappointed because he didn't get the position.
As it is raining, I will not go out.
Now that you mention it, I do remember.
(三)地点状语从句
引导地点状语从句的连词是where 和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
(四)目的状语从句
引导目的状语从句最常用的词(组)是so, so that(从句谓语常有情态动词), in order that, in case(以防，以免)等。
e.g. Speak clearly, so that they may understand you.
She has bought the book in order that she could follow the TV lessons.
He left early in case he should miss the train.
(五)结果状语从句
结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that (从句谓语一般没有情态动词), so … that, such … that等引导。
e.g. She was ill, so that she didn’t attend the meeting.
He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
(六)条件状语从句
条件状语从句分真实性(有可能实现的事情)与非真实性(条件与事实相反或者在说话者看来不大可能实现的事情)条件句。引导条件状语从句的词(组)主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：条件从句中的if 不能用whether替换。
e.g. If he is not in the office, he must be out for lunch.
You may borrow the book so long as you keep it clean.
So far as I know(据我所知), he will be away for three months.
You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.
If he had come a few minutes earlier, he could have seen her.
(七)让步状语从句
让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引导。注意：as引导的让步状语从句一般是倒装的。
e.g. Though he is a child, he knows a lot.
Child as he is, he knows a lot.
Whatever ( = No matter what ) you say, I’ll never change my mind.
(八)方式状语从句
方式状语从句常由as, as if (though), the way, rather than等引导。
e.g. You must do the exercise as I show you.
He acted as if nothing had happened.
(九)比较状语从句
比较状语从句常用than, so (as) … as, the more … the more等引导。
e.g. I have made a lot more mistakes than you have.
He smokes cigarettes as expensive as he can afford.
The busier he is, the happier he feels.
(十)使用状语从句时要注意的几个问题
1、在时间和条件(有时也在方式、让步等)从句中，主句是一般将来时，从句通常用一般现在时表示将来。
e.g. We’ll go outing if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shanghai.
2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致(或虽不一致，是it)，从句的谓语又包含动词be ，就可省略从句中的“主语 + be”部分。
e.g. When (he was) still a boy of ten, he had to work day and night.
If (you are) asked you may come in.
If (it is) necessary I’ll explain to you again.
3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。
e.g. You are to find it where you left it.(地点状语从句)
Tell me the address where he lives.(定语从句，句中有先行词)
I don’t know where he came from.(宾语从句)
Where he has gone is not known yet.(主语从句)
This place is where they once hid.(表语从句)
篇5：让步状语从句讲解英语六级

He is very old, but he still works very hard.
虽然他很老，但仍然努力地工作。
Though the sore be healed, yet a scar may remain.

典型例题
1） ___she is young, she knows quite a lot.
A. When B. However C. Although D. Unless
答案：C。意为虽然她很年轻，却知道许多。
2) as, though 引导的倒装句
as / though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）。
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意： a. 句首名词不能带任何冠词。
b. 句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
虽然他尽了努力，但他的工作总做的不尽人意。
3) ever if, even though. 即使

4) whether…or- 不管……都

5) “no matter +疑问词” 或“疑问词+后缀ever”

Whatever happened, he would not mind.
替换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意：no matter 不能引导主语从句和宾语从句。
（错）No matter what you say is of no use now.
（对）Whatever you say is of no use now.
你现在说什么也没用了。(Whatever you say是主语从句)
（错）Prisoners have to eat no matter what they‘re given,

篇6：并列句与状语从句讲解
连词是一种虚词，不能在句子中单独作句子成分，在句子中只起连接词与词、短语与短语、句子与句子以及从句的作用。
一、并列句与连词（连接同一语法类型的词、短语或句子）
1. 并列连词的分类并列连词按其作用可分为表示转折对比、因果、选择和并列四大类。
(1) 表示转折的并列连词
1. but（但是，可连接两个句子，用逗号隔开;也可以放在句首）
2. yet (然而,尽管如此，连接两个句子，用逗号隔开；也可以放在句首)
The car is old，yet it is in good condition.
注：yet也常放在完成时句尾表示还没有，此时不是连词，注意区分。
3. while (而,可是，表示转折或对比，不用加逗号)
Lily likes go to school by bus while linda likes go to school by bike.
4. however (然而,但是)，一般位于句首，单个使用后加逗号阅读完型中常见到表转折。 它们连接两个意思不同，阅读中遇到要注意。
(2) 表示因果的并列连词
表示因果的并列连词有：
1. for (因为) ①由并列连词for 引导的分句常置于句子后部，而且常用逗号与前面的
分句隔开。②for 分句主要是对前一分句补充说明理由或推断原因。③for 分句不能用来回答why 问句。She can’t go to school , for she is ill in bed.
2. so (所以) 可以连接两个句子，中间有时用逗号隔开；也可以放在一个句子的句首。 例：The shop doesn't open until 11 a.m. , so we should go there later..
3. therefore (因此),用法和however类似，但词义不一样
(3) 表示选择的并列连词
表示选择的并列连词有：or (或者)，either?or (不是??就是??，或者??或者??)
[注]①or用在祈使句中，意为“否则”，
Hurry up, or you’ll be late. 快点，否则你就会迟到了。
②or用在否定句中表示并列关系。
They never dance or sing. 他们从不跳舞，也不唱歌。
③either?or?连接主语时，谓语动词就近原则。
(4) 表示并列关系的连词(连接主语时注意谓语)
表示联合关系的连词有：
1. and (和，而且) and ①用在肯定句中连接并列的成分，表示“和，而且”；②用在祈
使句中，意为“那么”Study hard, and you will succeed. 努力学习，你就会取得成功。
2. both?and? () 谓语动词用复数Both you and he are right.
3. as well as (也) [注]谓语动词应与as well as 前面的主语在人称、数上保持一致。 I as well as he am a doctor. 我和他一样，也是医生。
4. not only?but also(不但??而且??)它连接主语时，谓语动词就近原则。
Not only I but also students are tired of take the examination.

Before（把我们说过的例句写下来让他们填）, after, when/while/as, since(自从，用于完成时+since+过去时 ),not…until, as soon as(一。。就。。) 等。

When: I was doing my homework when she came in.我正在写作业，这时他进来了。 ② not…until,前加点性动词。肯定句时用延续性动词
