状语从句用法详解
在主从复合句中修饰主句的动词、形容词、副词等的从句叫状语从句。
一般可分为：时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句、比较状语从句、方式状语从句。
I 时间状语从句：起时间状语作用的从句。
（时间状语从句位置灵活，可以在句首，也可在句末）
常用来引导时间状语从句的引导词有：when, while, as, after, before,
until/till, since, as soon as, immediately, the moment, every time, whenever等。
1.when, while, as
1) when“当......的时候”，表示主从句的谓语动作同时发生或先后紧接着发生。
I was very happy when I heard from you.
收到你的信时我非常高兴。
When you deal with them, you should be cautious.
跟他们打交道时，你应该谨慎。
when引导时间状语从句中的谓语动词可以用非延续性动词，也可用延续性动词。
When I was young, I went to town myself.
当我还年轻时，我自己独自去城里。（延续性动词）
When I lived in country, I used to carry some water for him.
我住在农村时，常常为他担水。（延续性动词）
When he received the letter, he'll tell us.
当他接到信后，他会告诉我们的。（非延续性动词）
When the fire broke out, all the students were sleeping soundly.
火灾发生时，所有的学生正在熟睡。（非延续性动词）
注意：当when引导的时间状语从句为系表结构，而且其主语和主句的主语一致，其表语又是一个名词时，就可以用由as引导的省略句来代替when引导的从句。如：
As a young man（=When he was a young man）, he was fond of hunting.
他年轻时喜欢打猎。
2）while引导的时间状语从句中谓语动词必须是延续性动词或表示状态的动词，侧重主句动作和从句动作相对比。
My father was preparing a report while I was playing games.
爸爸在准备一个报告，而我在玩游戏。
Please don't talk so loud while others are working.
别人在工作时，别高声谈话。
3）as表示从句和主句的两个动作交替进行或同时发生，可译为“一边......，一边......”
或“随着......”。
He hurried home, looking behind as he went.
他匆匆忙忙回家去，一边走一边回头望。
As time goes on, it's getting warmer and warmer.
随着时间的推移，天气变得越来越暖和了。
注意：如果主句表示的是短暂动作，而从句用延续性动词的进行时态表示在一段时间内正在进行的动作，此时when, while与as可互换使用。
When/ While/As I was walking down the street, I came across an old friend of mine.
当我沿大街行走时，碰巧遇到了我的一个老朋友。
2. till, until和not... until
1）肯定句：主句的谓语动词必须是延续性动词，主句、从句都为肯定式，意为“某动作一直延续到某时间点才停止”。
He remained there until/ till she arrived.
他在那一直等到她来。
You may stay here until/ till the rain stops.
你可以待在这里直到雨停。
2）否定句：主句的谓语动词必须是非延续性动词，从句为肯定式，意为“某动作直到某时间才开始”。构成not...until/till，意为“直到......才”。
She didn't go to bed until I come back.
你必须留在这儿直到我回来。
Don't worry. We won't set off until you arrive.
不要担心，你到了我们再出发。
3）till不可以置于句首，而until可以。
Until you told me the news, I had no idea of it.
直到你告诉我，我才知道这个消息。
4）not...until 句型中的强调和倒装用法。
直到你告诉我，我才知道这件事。
强调句型：It was not until you told me that I had any idea of it.
倒装句型：Not until you told me did I have any idea of it.
（not until置于句首，主句要用部分倒装结构）
Not until the clock struck 12 did she realize she must go home at once.
直到钟敲了12下，她才意识到她必须马上回家了。
3. before
1）before作“没有来得及......就”“未......就”“......就......”解时，强调主句谓语动词表示的动作发生得过早或过快。
Someone called me up in the night, but they hung up before I could answer the phone.
有人半夜给我打电话，但我还未来得及接他们就把电话挂了。
They had talked only a few minutes before they found they were quite different in opinion.
他们才谈了几分钟就发现他们的意见很不一致。
2）before作“......才......”解时，强调从句谓语动词表示的动作发生得太慢或太晚。
The bus driver almost knocked me down before he saw me.
那位公交车司机差一点把我撞倒，他才看见我。
The fire lasted about four hours before the firefighters were able to control it.
大火持续了大约四个小时，消防员才把火控制住。
3）before可译为“趁”“以免”“以防”等。
I'll do it before I forgot it.
趁还没有忘，我现在就把这事做了。
We'd better finish the work in time before the boss scolds us.
我们最好按时完成工作，免得挨老板骂。
4）before可译为“（宁可......而）不愿”。
He'd die before he apologizes to them.
他宁死也不向他们道歉。
I'd give up the plan before I turn to him for help.
我宁可放弃计划也不向他求助。
注意：“It + be + 一段时间+ before从句”中的主句和从句的时态有两种情况：如果主句用一般将来时，则从句用一般现在时，意为“多长时间以后某事即将发生”；
It won't be long before we meet again.
不久我们就会再见的。
如果主句用过去时，从句也用过去时，意为“多长时间以后某事才发生”。
It was 3 years before he came back from abroad.
三年后他才从国外回来。
4. since
译为“自从......”，主句常用现在完成时，从句常用一般过去时。
1）若since引导的状语从句的谓语动词是终止性的过去时，则从句表示的时间是“从动作开始的那一刻起”，这种情况比较常见。
He has studied very hard since he came to our school.
自从他来到我们学校，他学习就非常努力。
2）若since引导的状语从句的谓语动词是持续性动词或表示状态的动词的过去时，则从句表示的时间是“从那持续动作或状态结束时算起”。
I haven't heard any noise since I slept.
我醒后还未听到任何声音。（sleep为持续性动词，该动作结束时，即“醒来”时）
He has written to me frequently since I was ill.
自从我病愈以来，他屡次给我写信。（从句谓语为状态动词）
He has written to me frequently since I fell ill.
自从我生病以来，他就屡次给我写信。（从句谓语为终止性动词）
5. as soon as, immediately, directly, instantly, the moment, the minute, the instant,
no sooner... than... , hardly/scarcely... when...和once（一......就）
这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译作“一......就......”。从句中用一般时态代替将来时态。
The moment I heard the voice, I knew father was coming.
我一听到那个声音，我就知道父亲来了。
No sooner had we arrived at the station than the train left.
我们一到车站，火车就离站了。
The boy burst into tears immediately he saw his mother.
那男孩一见到他妈妈便放声大哭。
注意：no sooner...than; hardly... when...这一结构的时态搭配：
no sooner与hardly引导的句子的谓语动词应用过去完成时，
而than与when引导的句子的谓语动词应用一般过去时。
此外：当把no sooner和hardly提到句首时，应用倒装语序。
I had hardly got home when it began to rain.
Hardly had I got home when it began to rain.
我一到家天就下起雨来。
6. every time, each time, next time, the first time, any time, all the time等名词短语用来引导时间状语从句，表示“每当......；每次......；下次......”等。
Every/ Each time I was in trouble, he would come to help me out.
每当我处于困境，他就会来帮助我。
Next time you come, do remember to bring your son here.
下次你来的时候，一定记着把你儿子带来。
The last time she saw James, he was lying in bed.
上次她看见詹姆斯的时候，他正躺在床上。
7. 名词性短语充当连词引导时间状语从句
表示时间的名词短语也可以引导时间状语从句，且意义丰富，如：
any time任何时候都by the time 到......时候
every time/ each time每当......时the frist time第一次......时
I think of the things and the people when we studied there every time I go by my mother School.
每当我经过母校时都会想起我们在那儿学习时的事情和人们。
II 地点状语从句：在句中作地点状语的从句称为地点状语从句，可置于句首、句中或句尾。
地点状语从句常用的引导词有where, wherever, anywhere, everywhere,
nowhere等。
Make marks where you have questions.
在有问题的地方作出标记。
You can go anywhere you like.
你可以到你想去的任何地方。
Where there is a will, there is a way.
有志者事竟成。
注意：地点状语从句与定语从句的区别
where引导定语从句时，从句前应有一个表示地点的词作先行词；
而状语从句前则无需用先行词。
Go back where you came from.
你从何处来回何处去。（where引导地点状语从句）
Go back to the village where you came from.
回到你来的那个村子里去。（where引导定语从句，修饰village）
You'd better make a mark where you have any questions.（状语从句）
You'd better make a mark at the place where you have any questions.（定语从句）
where 引导的地点状语从句一般可以转化为定语从句，只要在where前加上
“to/in/from+the place/places/any place(s)等”结构即可。
III 让步状语从句
引导让步状语从句的连词有although, though, as, even if, even though, while, whether...or..., whether(...) or not, whatever, no matter what/ how/ why等。
1. though/although引导的让步状语从句
1）although和though意义相同，都意为“虽然，即使”，表示让步，一般情况下可互换使用，区别在于although语气较重，大多置于句首。
2）though/ although引导让步状语从句时，主句若用yet或still引出，更加强调对比性，但不可出现but。
3）though引导的从句可以把表语、状语、动词等提至句首。在as though, even though 中一般不可用although代替。同时although不可当副词用，而though则可。
Although it's raining, they are still working in the field.
虽然在下雨，但他们仍在地里干活。
Short though it is, the article is very important.
那篇文章虽然很短，但很重要。
注意：though还可用作副词，意为“可是，然而”，置于句末。
He said he would come; he didn't, though.
他说他会来，可是没有来。
2. even though/ even if 引导的让步状语从句
这两个短语表示语气更强的让步，常常意为“再退一步说”。
even though更强调对“既成事实”的让步：
Even though he is poor, she loves him. (= He is poor, yet she loves him.)
尽管他很穷，但她还是爱他。
even if 则强调对“假设”的让步。
Even if he is poor, she loves him. (= He may be poor, yet she loves him.)
即使他很穷，但她还是爱他。
3. as引导的让步状语从句
as引导让步状语从句时，从句中的表语、状语以及谓语中的实义动词需提前至从句句首，作表语的单数可数名词前如有冠词，冠词需要省去。
Child as/ though he was, he knew what was the right thing to do.
= Though he was a child, he knew what was the right thing to do.
虽然他是一个孩子，但他知道该做什么。
Much as/ though I like it, I won't buy it, for it's too expensive.
虽然我很喜欢它，但我不会买，因为它太贵了。
Try as you may, you will never succeed.
你尽管试，但你绝不会成功的。
注意：though引导的从句也可以像as引导的从句一样用倒装语序，但是although引导的从句只能用正常语序。
Smart though/ as she is, she doesn't study hard.
Though she is smart, she doesn't study hard.
Although she is smart, she doesn't study hard.
4. whether.. or/ whether (...) or not引导的让步状语从句
whether... or/ whether (...) or not表示“不论是否”“不管是......还是”之意。该复合连词
引导的让步状语从句表示正反两个方面的可能性都不会影响主句的意向或结果。
You'll have to attend the ceremony whether you're free or busy.
不管你忙不忙，都必须要参加这个典礼。
Whether you believe it or not, it's true.
无论你是否相信，这都是真的。
5. while引导的让步状语从句
while也可以引导让步状语从句，表示“尽管”，比though/ although语气弱。while引导的让步状语从句一般要位于句首。
While I like the color, I don't like the shape.
我虽然喜欢那颜色，但不喜欢那形状。
While I understand what you say, I can't agree with you.
虽然我理解你的意思，但我还是不同意。
6. what-ever类词引导的让步状语从句
在英语中，wh-ever类词可作疑问词，也可引导名词性从句，还可引导让步状语从句。这类词在引导让步状语从句时常可换成“no matter+wh-词”，但在引导名词性从句时只能用wh-ever类词。
I'll wait for you however (no matter how) late it is.
不管有多晚我都会等着你。
Whoever (No matter) you are, you must keep the law.
不管你是谁，你都要遵纪守法。
注意：“no matter+疑问词”结构只能引导让步状语从句，而wh-ever类词还可以引导名词性从句或其他状语从句。
I'll eat whatever you give me.
你给我吃什么，我就吃什么。（what引导宾语从句）
Whoever comes will be welcome.
不管谁来都受到欢迎。（whoever引导主语从句）
IV 原因状语从句
在主句中作原因状语的从句称为原因状语从句，可置于句首，也可置于句尾。
引导原因状语从句的常用词可分为两类：单词引导如because, as, since等，短语引导如now that, for the reason that, in that, seeing that等。
1. because, as, since用法
这三词都有“因为”之意，但用法和具体内涵各异。
1）because语气最强，用以回答why引起的提问，可表示已知或未知的事实。它可和强调词only, merely, just及否定词not连用，所引导的从句常位于主句之后，只有强调时才置于主句之前。它还可用于强调结构。
She was afraid to move because a snake was lying beside her.
她不敢动弹，因为一条蛇就躺在她旁边。
－Why did they fail? 他们为什么失败？
－It was because they didn't do their best. 因为他们没尽力。
2）as语气弱，较口语化，所表达的原因比较明显，或是已知的事实，故不需要强调。
as从句之前不可用强调词和not，且不可用于强调结构，as从句多置于主句之前。
As he was in a hurry, he left his bag home.
由于他太匆忙才把包丢在家里了。
As it was a public holiday, all the shops were shut.
由于这是一个公共假日，所有商店都关门了。
3）since的语气比较弱，常表示对方已知的事实，往往相当于汉语的“既然”。它和as 一样，其前亦不可用强调词和not，不可用于强调结构，since从句多置于主句之前。
Since Monday is Bob's birthday, let's give him a party.
既然星期一是鲍勃的生日，咱们举行一个宴会吧。
Since you are free tonight, why not drop in and play chess with me?
既然你今晚没事，为什么不来和我下棋呢？
注意：上述三个词为从属连词，而for是一个并列连词。for有时可用来作附加说明，必须把其引起的句子放在某一句子之后。
We should be more careful, for it is already dark.
天已晚了，我们应更小心些。
2. now that的用法
now that主要用于口语，表示微弱的原因，主、从句的因果关系不明显，常译为“既然”。
that有时可以省略。
Now that you have come, you may as well stay.
既然你已经来了，最好留下来。
Now that everything is settled, I have no reason here.
既然事情办完了，我就没有理由留在这儿了。
3.for the reason that的用法
that后是一个同位语从句，解释说明reason的内容。
I often go to the concert for the simple reason that I love music.
我经常去听音乐会，原因很简单，那就是我喜欢音乐。
For the reason that I haven't worked hard, I'll have to cram before the coming examinations.
由于平时不努力，考试前我只好临时抱佛脚。
4.in that的用法
这个短语常用于书面语中，表示“由于某种原因”。
The experiment is worth trusting in that it is based on scientific facts.
这个实验值得信赖，因为它是建立在科学事实基础上的。
I like the city, but I prefer the country in that there's fresher air.
我喜欢城市，但我更喜欢乡村，因为那里有更清新的空气。
5.that后的从句
be happy that, be surprised that等中的that从句有时也被认为是原因状语从句。
I'm sorry that I haven't done so much as I should.
对不起我没有做我该做的那么多。
We feel proud that our country is getting stronger and stronger.
我们为我们的国家越来越强大而感到自豪。
V 方式状语从句
在主句中作方式状语的从句称为方式状语从句。方式状语从句常用的引导词有as, as if/though等。
1.as引导方式状语从句。
You must do the experiment as I do.
你要像我这样做实验。
You are fine just as you are.
你现在这样子就好极了。
2.as if/ though引导方式状语从句。
1）as if/ though引导的方式状语从句所表示的情况是事实或具有很大可能性时，通常用陈述语气；
She closed her eyes as if she was tired.
她闭上了眼睛好像累了。（事实，谓语用陈述语气）
2）如果从句所表示的情况不是事实，而是主观的想象或夸张性的比喻，通常用虚拟语气。
（现在的情况用过去的时态，过去的情况用过去完成时。）
They completely ignore these facts as if/ though they never existed.
他们完全忽略了这些事实，就仿佛它们从未存在过。
（与事实相反，谓语用虚拟语气。）
注意：as if/though也可以引导一个分词短语，不定式短语或无动词短语。
He stared at me as if seeing me for the first time.
他目不转睛地看着我，就像第一次看见我试的。
He cleared his throat as if to say something.
他清了清嗓子，像要说什么似的。
The waves dashed on the rocks as if in anger.

状语从句讲解及习题附答案
（一）状语从句概述 定义状语从句用作状语，是起副词作用的句子。 位置状语从句可以放在主句之前，也可以放在主句之后，时间、条件、原因和让步状语从句放在句首时需要用 逗号和主句隔开。 分类根据其作用可以分为时间、地点、原因、条件、目的、让步、方式和比较等状语从句。 作用它可以修饰谓语、非谓语动词、定语、状语和整个句子。 （二）状语从句详解 1. 时间状语从句 引导词用法示例 when 意为“当…的时候”。When 引导从句的谓语动词可以 是延续性动词，也可以是 瞬间动词。并且when有 时表示“就在那时”A liar is not believed when he speaks the truth.说谎者讲真话时也没有人相信。When he arrives, I’ll call you. When you laugh and smile, your body relaxes. while 意为“在…的时候，在…的 同时”。While引导从句的 谓语动词必须是延续性While I was standing at the window, I saw several boys running along the street.
的，发生时间较长，并强调主句和从句的动作同时发生（或者相对应）。While 有时还可以表示对比。While John was watching TV, his wife was cooking. as 意为“一边…一边…”。As 引导的动作是延续性的， 发生时间较短，一般用于 主句和从句动作同时发 生；as也可以强调一前一 后。The writer was angry as he was travelling on a train to London because someone had invaded his “space”. He smiled as he stood up. after 意为“在…之后”。表示主句 动作发生在从句动作之 后。主句与从句的动作时 间关系与before引导的从 句相反。With many hungry visitors waiting, don’t stay too long at your table after you have finished. If an early exit is necessary, you can leave after a scene is over. before 意为“在…之前”。引导的从 句不用否定形式的谓语， 并且当before引导的从句 位于主句之后，有时译成 “就，才”。当主句用将来时，You can’t watch TV before you finish your homework. Before it ended, the theatre was almost empty. My father had left for Canada
状语从句用法讲解和练习汇编
第章状语从句 学习指导 状语从句在句子中作状语，用来修饰主句或主句的谓语。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。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的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： 状语从句分九类： 在这一章节的学习中，要求同学们掌握各类状语从句基本概念，并能够灵活应用 第一节时间状语从句 1. 时间状语从句用一般现在时表示将来。连接时间状语从句的连接词有: 2. when，while，as均可表示当.... 的时候” when强调特定时间”表示主句谓语动词的动作与从句谓语动词的动作是同时发生的， 或从句的动作发生在主句的动作之前；while表示的时间是一段，而不是一点，as多用在口 语中，强调同一时间”或一前一后”有时还有随着”的含义。 I'll go on with the work when / come back tomorrow .我明天回来后会继续做我的工作。 When spring came, he felt like a trip.春天来了，他想去旅游。 As spring warms the good earth，all flowers begin to bloom . （as 有随着”的含义） as, when, while 都表示主、从句的动作或状态同时发生，但三者也有区别。as和when引导的从句既可表示一点时间，也可表示一段时间，从句中的谓语动词既可以是持续性动词，也可以为短暂性动词，经常可以互换使用；while引导的从句通常表示一段时间，从句中宜 用持续性动词作谓语。当从句中的谓语动词为持续性动词时，这三者可以通用（前面例句中 已有体现），再如： Mother was worried because little Alice was ill, especially as / when / while father was away in France. 妈妈担心，因为小艾丽思病了，特别是当父亲远在法国的时候。 如果从句和主句要表示一个人的两个动作交替进行或同时完成时，则多用as，可译为“一

高中英语状语从句讲解汇总 原因从句 除了下面A2，A3中所示各种类型外，这两种从句均可由as或because来引导。但是用as引导原因从句较为稳妥（参见A）；用because引导结果／原因从句较为稳妥（参见B）。 A 原因从句 1 由as／because／since 引导的原因从句： We camped there as／because／since it was too dark to go on． 我们在那里露宿是因为天太黑，不能再继续往前走了。 As／Because／Since it was too dark to go on，we camped there． [ 因为天太黑不能再继续往前走，我们就在那儿露宿了。 2 in view of the fact that可用as／since／seeing that来表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand． 既然你在这儿，你就帮我个忙吧。 As／Since／Seeing that Tom knows French，he’d better do the talking． 既然汤姆懂法语，最好让他来谈。 3 在as／since／seeing that意指以前共知的或共知的陈述时，可用if来代替： ~ As／Since／Seeing that／If you don’t like Bill，why did you invite him 既然／如果你不喜欢比尔，你为什么邀请了他 注意：if so的用法： —I hope Bill won’t come． —If so（＝If you hope he won’t come），why did you invite him —我希望比尔别来。 —如果这样（=如果你希望他不来），你为什么邀请了他 关于if＋so／not，参见第347节。 ~ B 结果从句由because或as引导： The fuse blew because we had overloaded the circuit． 保险丝烧断了，因为我们使线路超载了。 He was angry because we were late． 他生气是因为我们来晚了。 As it froze hard that night there was ice everywhere next day． 因为那天晚上冷得厉害，所以第二天到处都是冰。 ~ As the soup was very salty we were thirsty afterwards． 因为这汤很咸，后来我们渴得厉害。

语法讲解 时间状语从句的用法解析及练习
语法讲解时间状语从句的用法解析及练习 状语从句在复合句中作状语，其位置较灵活，可以在主句之前、之后或中间(放在句首时状语从句后面常用逗号，放在句末时状语从句前面往往不用逗号)。根据状语从句的含义，状语从句主要分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、结果状语从句、条件状语从句、让步状语从句等八种。掌握以上各种状语从句的关键在于把握其相应的引导词。以下是对时间状语从句的基本用法进行小结，希望可以帮助到同学们有一更深的理解。 时间状语从句的引导词 when, before, after, as, while, till/until, since，whenever 时间状语从句的用法 时间状语从句的引导词所表示的意思不尽相同，要注意把握不同的时间状语从句的引导词所表示的不同时间关系，以及它在具体句子中对应的对应时态、语态等问题。 1. when、as、while引导的时间状语从句分析： (1) when引导时间状语从句时表示“当……的时候”，when既可以指时间段也可指时间点，从句中既可用延续性动词又可用非延续性动词，且动作既可和主句的动作同时发生又可在主句的动作之前或之后发生。 注意体会如下例句：I’ll call you when I get there. 我一到那里就给你打电话。// When the wind blows, all the doors rattle. 只要风一吹，这门就吱嘎作响。// He stopped trying, when he might have succeeded next time. 他不再试了，其实他可能下一次就成功。// When I came home my wife was cooking dinner. 我回家时，妻子在做晚饭。 如果when引导的时间状语从句的主语与主句主语相同，而从句的谓语又是be动词时，那么从句中的主语和be可以省略;当when引导的时间状语从句的主语与主句主语相同时，往往还可以用“when+分词”的形式替代该状语从句。例如：When (you are) in trouble, ask her for help. 当你遭遇麻烦的时候去向她求助。// When I came into the room (=When coming into the room), I found him lying there asleep. 当我进入房间的时候，我发现他躺在那儿睡着了。 (2) while引导时间状语从句时表示“当……的时候”，它强调主句的动作与从句的动作同时持续地进行，用于这一用法时while引导的时间状语从句和主句中的谓语动词必须是延续性动词，或者主句的动作发生在从句动作的进行过程中，主句中的谓语动词通常是非延续性动词，例如：Study while you study; play while you play. 该学习的时候就学习，该玩的时候就玩。// I met her while I was at school. 当我在学校的时候我遇见了她。 (3) as引导时间状语从句时表示“当……时，一边……一边……”，侧重表示两个动作同时发生(包括一个主语同时进行两个动作)，或者一种动作随着另一种动作的变化而变化。例如：He jumps as he goes along. 他边走边跳。// I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤。// I saw him as he was getting off the bus. 正当他下公共汽车时, 我看见了他。// As the wind rose the noise increased. 刮风的时候噪声增大。

高中英语状语从句讲解
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3.
