一、时间状语从句:
1、时间状语从句通常用下列从属连词来引导：after, before, as, once, till, until, (ever) since, when, whenever, while, now (that), as long as, as soon as。如：
Now (that)you’ve gr own up, you must stop this childish behaviour. Whenever we met with difficulties, they came to help us.
Come and see us whenever you have time.
People do not know the value of health till they lose it.
2、有些词，如immediately, directly, instantly 等，当用于as soon as 意义时，也可以引导时间状语从句，如：
I got in touch with him immediately I received his letter.
My sister came directly she got my message.
The machine will start instantly you press the button.
I’ll t elephone you directly I hear the news.
Will you look for it immediately you get there?
3．某些表示时间的名词词组，如the (very) moment ( = as soon as ), the minute ( = as soon as ), the instant ( = as soon as ), the day, the year, the morning, every time, each time, next time, the first time 等，也可以引导时间状语从句，如：
I’ll tell you about it the moment you come.
I started the instant I heard the report.
The instant she saw him she knew he was her brother.
Every time I catch a cold, I have pain in my back.
I’m going to see him next time he comes to Shenzhen.
He left Europe the year World WarⅡbroke out.
He had impressed me that way the first time I met him.
I started the very moment I got your letter.
I’ll tell him the minute (that) he gets here.
4．有些关联从属连词，如no sooner …than / hardly …when / scarcely …when / barely …when 等，也能引导时间状语从句。
△如果把no sooner, hardly, scarcely, barely 置于句首，它所连带的这部分就要倒装，如：
She had no sooner heard the news than she fainted.
= No sooner had she heard the news than she fainted.
They had hardly started to work when the trouble began.
= Hardly had they started to work when the trouble began.
He had scarcely entered the room when the phone rang.
= Scarcely had he entered the room when the phone rang.
二、地点状语从句:
1、地点状语从句常用where, wherever 来引导，如：
We will stay where you stay. (where = in the place in which; where 既连接主句与从句，又在从句中作副词修饰谓语stay。)
I found my books where I left them.
Wherever he happens to be, John can make himself at home.
He will work wherever the people need him.
Let me go wherever (= to any place to which) they like (to go).
2、有时，- where 构成的复合词也可以引导地点状语从句，如：Everywhere they went, they were kindly received / warmly welcomed. We’ll go anywhere the Party directs us.
三、方式状语从句:
1、方式状语从句通常由as, as if, as though 来引导，如：
You must do the exercises as I show you.
Please do exactly as your doctor says.
It looks as if it might snow / is going to snow.
He acted as if / though nothing had happened.
He walked as if he was / were drunk.
Mary was behaving as though she h adn’t grown up.
2、在非正式文体或口语中，也可用the way (that) (= as = in the way in which), how, like 等来引导，如：
Jean doesn’t do it the way I do.
She is doing her work the way I like it done.
You can do the job how you like.
The landlord was watching him like(= just as) a cat watches a mouse. Do you make bread like you make cakes?
like 作连词的用法补充说明：
1). Conjunction (informal)(非正式)：in the same way that; as
同…一样，如
People who change countries like they change clothes.
换国籍像换衣服一样的人。
2). as though; as if 好像，如同
I felt like I'd been kicked by a camel. 我觉得好像被骆驼踢了似的。
四、程度状语从句：
程度状语从句可用to such an extent that … / to such a degree that … , to the degree/ extent that, in so far as （“在…的范围内”）等来引导，如：
The temperature rose to such an extent that the firemen had to leave the
burning building.
The temperature lowered to such a degree that the water froze.
试比较：
The temperature rose so high that the firemen had to leave the burning building.
The temperature lowered so much that the water froze.
从以上例句可以看出，程度状语从句往往也表示达到某种程度时所引出的结果，所以程度状语从句和结果状语从句在意义上有相通之处。At that time politicians were not known to the degree that they are today. 那时政治家们并不像今天这样为人所知晓。
I'll help you in so far as I can. 我会尽我所能帮助你。
五、原因状语从句：
1、引导原因状语从句最常用的连词是because, since, 和as，所引导的从句可以放在主句之前，也可放在主句之后。其中because 语势最强，since 次之，as 又次之。
△because通常表示说话人认为这种理由或原因是听话人所不知道的，全句强调的重点在原因上，不在主句表示的结果上。回答why 提出的问题时，只能用because；在强调句型中也只能用because从句，不能用since, as等，如：
Because I can’t se e very well, I have to sit near the front.
It was because he was ill that he didn’t go wit h us.
It was because he was ill that he didn’t come.
△since 和as 引导的句子，重点在主句的内容，其原因或理由在说话人看来已很明显，或已为听话人所熟悉，since 和as 只是一种附带的说明原因，不是对原因进行强调，如：
As he is working hard, he is likely to succeed.
Since he can’t answer the question, you’d bet ter ask someone else.
As / Since he was not at home, I spoke to his brother.
Since you insist, I will reconsider the matter.
As he was in a hurry, he left his bag at home.
△for 是并列连词，它引导的句子只能后置。表示因果关系时，可以和because 换用；但当它用于对主句的内容加以解释或推断时，不能用because 代替，如：
He couldn’t have seen me, because / for I was not here.
The ground is wet, for / because it rained last night.
It rained last night, for the ground is wet this morning.
△because 之前可以加上simply, only, just 等强调词，如：
You shouldn’t get angry just because some people speak ill of you.
2、复合连词也可以引导原因状语从句，这些连词有：now (that), seeing (that), considering (that), for the reason that, by reason that, for fear that, that等，如：
Now (that) (= Since) you mention it, I do remember.
Now (that)he is absent, you’ll have to do the work by yourself.
Now (=Since) the rain has stopped, let’s start.
Seeing (that) all the guests have arrived, let’s have dinner.
She didn’t go for fear that she would get lost.
He has done very well, considering (that) he has no experience.
I haven’t finished writing the report yet,not that (= not because) I dislike the work, but that (= but because) I have not time. Considering that they are just beginners, they are doing quite a good job.
3、在“主语+ be + 形容词+ that ”句型中，主语通常是人，形容词通常为：glad, happy, pleased, sorry 等表示感情的形容词，这时that 可以看作原因状语从句，如：
We are glad that (= because) we have reaped another bumper harvest. I’m glad (that) you are all right.
We are sure that our team will win.
I’m pleased that you have decided to come.
六、结果状语从句
结果状语从句往往放在主句之后，通常主句是因，从句是果，这和原因状语从句刚好相反，例如：
He was ill, so that he didn’t come.
He didn’t come because he was i ll.
1、结果状语从句通常用下列连词引导：so …that, such (a) …that, such that, so that, that 等，例如：
He was so angry that he left the room without saying a word.
The book is written in such simple English that we beginners can
understand it without much difficulty.
It was such a bad accident that several people got injured.
His diligence was such that he made great progress.
He did n’t plan his time well, so that he didn’t finish the work in ti me. She worried so that she could hardly eat her supper.
What have I done that you should be so angry with me?
2、应注意的几个问题：
①在非正式文体中，由so…that, such (a)…that引导的结果状语从句，往往可以省略连词that，这时，从句之前往往用逗号与主句隔开，在口语中则用停顿表示省略。
He was so tired (,) (that) he could hardly stand.
Peter is such a good boy (,) (that) he is loved by everybody.
You walk so fast (that) I can’t keep pace with you.
We left in such a hurry (that) we forgot to lock the door.
He was so rude (that) she refused to speak to him.
②当so 修饰动词时，后面应稍停顿，如：
His heart beat so Δ that he could hardly breathe.
She worried so Δ that she could hardly eat her supper.
③当so位于句首时，主句的语序应倒装，如：
So badly was he injured that he had to go to the hospital.
So small was the mark that I could hardly see it.
七、目的状语从句
1、目的状语从句通常使用的连词有：so that, in order that, that, so。否定的句式常用lest, in case, for fear that 来引导。
△目的状语从句中一般要有can, may, could, might, will, would, should 等情态动词，如：
Bring it closer (so) that I may see it better.
I put down his address for fear that I should forget it.
The teacher must speak clearly so that his students can / may understand well.
We’ll sit nearer the front so we can hear better. (非正式或口语)
The driver looked over the engine carefully lest it (should) go wrong on the way.
Please remind me of it again tomorrow in case I forget.
Take an umbrella with you, in case (= for fear that) it rains / it may rain / it should rain.
He left early in case he should miss the train.
2、so that / so既可以引导目的状语从句，又可以引导结果状语从句，其区别可以根据上下文的意义来判断，也可以从其结构上来判断。①凡在讲话时，so that / so从句之前有停顿，在文字中so that / so 从句之前有逗号，则为结果状语从句，否则为目的状语从句，如：We all arrived at eight, so (that) the meeting began promptly. (结果状语从句)
We’ll come at eight so (that) the meeting can begin early. (目的状语从
句)
②有时，由so that或so 引导的结果状语从句之前并没有逗号，这时，就要看从句中有没有can, may, could, might, will, would, should 等情态动词，如果有，多半是目的状语从句，如果没有，多半是结果状语从句，如：
I am going to the lecture early so that I’ll get a good seat. (目的状语从句)
I went to the lecture early so that I got a good seat. (结果状语从句)
③目的状语从句可以移至句首，而结果状语从句不能前移，如：So that he could be heard in every room, John spoke through a microphone. (目的状语从句)
John spoke through a microphone so that he was heard in every room. (结果状语从句)
八、条件状语从句
1、条件状语从句通常用下列连词引导：if, unless, supposing (that)（仅在问句中使用），suppose (that), in case, so / as long as, so far as, on condition (that), provided (that) 等，例如：
In case he comes, let me know.
You can go out, as / so long as you promise to be back before eleven.
I will come again tomorrow provided (that) I have time. (= if) Supposing (that) it rains tomorrow, what shall we do? (= if)
Unless you tell him yourself, he’ll lose f aith in you completely.
We’ll let you use the room on condition that / provided that you keep it clean and tidy.
2、有时可以把祈使句作为条件从句，祈使句后面要搭配and，如：Come tomorrow, and I will tell you.
(= If you come tomorrow, I will tell you. )
Give him an inch and he’ll take a mile.
(= If you give h im an inch, he’ll take a mile. )
注：当表示否定的条件时，可用连词or 或otherwise，如：
Hurry up, or (else) you’ll be late.
Make up your m ind, or you’ll miss the chance.
Start at once, or / otherwise you’ll miss the train.
(= If you do n’t start at once, you’ll miss th e train. )
(= Unless y ou start at once, you’ll miss the train.)
3、if only是if的强调式，通常表示说话人强烈的愿望, “但愿, 真希望”，如：
If only it clears up, we’ll go.
If only somebody had told us, we could have warned you.
如果有人告诉了我们，我们就会让你提防的。
注：if only 引导的状语从句有时可以不依附于主句而独立存在，表示说话人的希望、愿望或遗憾等心情，如：
If only he comes in time. (= I hope he will come in time.)
If only he didn’t drive so fast.(= I wish he didn’t drive so f ast.)
If only I hadn’t been late for work.
(= I wish I hadn’t been late for work.)
4、在真实条件句中，从句动词通常用一般现在时表示将来时间，主句通常带有情态动词，如：
If you move, I’l l shoot you.
If I press this button, what will happen?
If you come, you can see it.
If you finish early, you may go.
注①当从句表示将来已经完成或正在进行的动作时，动词用现在完成时或现在进行时，如：
I will return the book on Monday if I have read it.
Th e police won’t take your car away if you are sitting in it.
注②如果从句表示现在的意图、意愿、决心等，则可以用will / shall，如：
If you will read the book, I’ll let you have it.
If you will help me, we can finish by six.
If you will give up smoking / drinking, your health will improve.
5、有一种条件句，其从句动词不管主语的人称和数如何，一律用“should + 不定式”，主句动词可根据意义需要采取不同形式，如：If he should hear of your marriage, he would be surprised.
If you should hear the news, please let us know.
If you should be interested, I’ll tel l you the whole story.
If it should rain, we had better stay indoors.
If he should come tomorrow, I would tell him everything.
注：在正式文体中，可用should I (we, you etc) 代替If I (we, you etc.) should …，如：
Should I be free tomorrow, I will come.
Should you see Mike, will you ask him to ring me up?
Should you see my mother, tell her I am quite well.
6、非真实条件句：
①当从句表示与现在事实相反的条件时，从句动词用一般过去时或were型虚拟式，主句动词用would / should / could / might + 不定式，如：
If I were you, I should consult a doctor.
If I lived in the twenty-first century, my life might be different in a number of ways.
②当从句表示与过去事实相反的条件时，从句动词用过去完成时，主句动词用would / should / could / might +不定式完成式，如：
If he had tried hard last term, he would have succeeded.
If he had taken his doctor’s advice, he might not have died.
③当从句表示将来不大可能实现的条件时，从句动词用一般过去时或were / was to +不定式，主句动词用would / should / could / might +不定式，如：
What would you do if it snowed tomorrow?
He wouldn’t do it unless you were to order him to.
④在正式文体中可用“were +主语”等倒装结构代替“if +主语+ were”等结构；“had +主语+ ed分词”代替“if +主语+ had + ed分词”结构，如：
Were I in your place, I would be very worried.
Were John to go to the university, he would have to work hard.
Had the captain been more careful, his ship would not have been sunk. Had it not been for the expense, I should have gone to Italy.
7、unless 与if …not 的用法比较：
If you do n’t start at once, you will miss the train.
Unless you start at once, you will miss the train.
unless 在意义上相当于if …not ，在有些场合两者可以交替使用，但在有些场合又不可以互换，以下是不可互换的情况：
①当if…not 引导非真实条件状语从句时，一般不可以改用unless，例如：
If she weren’t so silly, she would understand. (事实上她很傻，改成Unless she were so silly…含义为她不傻)
If I hadn’t stopped her, she would have jumped into the river. (事实上我阻止了她，改成Unless I had stopped her…含义为我没有阻止她。)
②unless 表示除外的唯一条件，因此通常不能用and 连接两个unless 从句，而if …not 则不受此限，如：
She won’t lose weight if she does not keep a diet and if she does not
take exercises every day.
She won’t lose weight unless she keeps a diet and takes exercises every day.
(不说：unless she keeps a diet and unless she takes exercises every day.)
③unless 从句中可用否定词，而if …not 从句中不可再加否定词，因此在unless 引导的否定从句中，不可用if …not 代替unless ，如：
I will go unless no one else does.
I will go if no one else doe sn’t. ×
Don’t ask me to explain unless you really don’t understand.
D on’t ask me to explain if you really not don’t underst and. ×
④在if…not 从句中通常用非肯定词，而在unless 引导的肯定形式的条件从句中，通常用肯定词，而不用非肯定词，如：
I will be very angry if you haven’t spoken to her yet.
I will be very angry unless you have already spoken to her.
九、让步状语从句
1. 引导让步状语从句的主要连词有although, though, as, even though / if等。
He is unhappy though he has a lot of money.
虽然他很有钱，但他不快乐。
They will stand by you even if you fail.
即使你没成功，他们也会支持你。
注意：although/though不可与but连用，但可与yet, still等连用。例如。
Though it was raining hard, yet they went on playing football. 虽然雨下得很大，但他们仍然继续踢足球。
2. as引导让步状语从句时，需倒装，从句中的表语和状语或动词原形要置于句首；though引导时，倒装或不倒装皆可。如表语是名词，不可加冠词；若动词原形前置，从句要有may或might。例如：Child as he is, he knows a lot. 尽管是个孩子，他却懂得很多。Try as he might, he could not find a job.
不管怎么努力，他还是找不到工作。
3. when和while也可引导让步状语从句，意为“虽然”。例如：While they are my neighbors, I do not know them well.
虽然他们是我的邻居，但我并不很熟悉他们。
4. whet her…or…可引导让步状语从句，意为：不管是……还是……，不论是否……。例如：
You will have to attend the ceremony whether you are free or busy. 不管你忙不忙，你都要参加这个典礼。
5. whatever, whoever, whichever, however, when-ever, wherever等与no matter w hat/ who/ which…等也可引导让步状语从句，意为“不管……, 不论……”。
Whatever/ No matter what you say, he will not believe you.
不论你说什么，他都不会相信你。
5) 其它引导短语：granted/granting that, admitting (that), in spite of /despite the fact that
Granted(假定;就算)that he has enough money to buy the house, it doesn’t mean he’s going to do so.
He went out in spite of the fact that he had a bad cold.
十、比较状语从句
比较状语从句一般由从属连词as或than来引导，这种从句常采用省略句的句型，如：
He worked as fast as a skilled worker.
The project was completed earlier than we had expected.
He is as young as you (are young).
Please come as soon as (it is) possible.
区别：We know you better than he (knows you).
We know you better than (we know) him.
注①在否定句中，用as…as 或so…as 均可，但后者语气更强调，如：
He is not as / so young as you.
注②the…the…句型也是比较状语从句的一种，例如：
The harder we work, the better we shall serve the people.
其中the 为连接副词，既起连接作用，又修饰后面的副词。
注意省略：
The sooner he comes, the better (it will be).
The higher the ground (is), the cooler the air (will be).
十一、as far as 或so far as 可以引导状语从句，有些语法书将其称之为“限制状语从句”。
as far as/ So far as表示“在……的范围内”，引导限制状语从句。多用于下列结构：as far as /so far as I know（据我所知），
as far as /so far as I can see,
as far as /so far as I’m concerned（依我看）。
例如：
As far as / So far as I know, the couple have been abroad for about five years. 据我所知，这对夫妇已经出国约五年了。
There’s only one thing to be done now, as far as I can see.
依我看。现在只有一件事情要做。
As far as / So far as I can see, this is a thorny(棘手的)problem.

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
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。

高中英语状语从句用法详细解析 一、定义： 在句中作状语的从句是状语从句，修饰主句中的动词、形容词或副词等。状语从句由从属连词引导，从属连词在句中不充当句子成分，只起连接作用，状语从句放在句首时，要用逗号，放在句尾时不用。 二、分类 根据意义上的不同，状语从句可分为：①时间状语从句②地点状语从句③原因状语从句④目的状语从句⑤条件状语从句⑥结果状语从句⑦让步状语从句⑧方式状语从句⑨比较状语从句 三、时间状语从句 （一）引导时间状语从句的连词有：as, when(whenever), before, after, as soon as, until(till), since, every time, once. （二）、“as” as, when, while都有“当……的时候”，可以互用When she was a child. While she was a child. She Lived in Paris. As she was a child. as有“一边…一边”的意思 He sang as he walked. “when” When the clock struck twelve, all the lights went out. I was sleeping when she came in. 动补 When we arrived at the station, the train had left. “while” 主、从句动作或状态同时发生。用while引导的从句用延续性动词，常表示较长的时间或一个过程。 While we were having supper, all the lights went out. Please keep quiet while others are studying. While I was writing letters last night, he was watching TV. when, while并列连问。when和while都可用作并列连问，连接并列分句。When表示“就在……的时候”, while意反而，可是，表示转折。
让步状语从句的讲解与用法(精选课件)
让步状语从句的讲解与用法让步状语从句是状语从句中的一种，其本身也是状语从句.一般翻译为“尽管……”或“即使……"，就是我们日常生活中用的“退一步说……"的感觉。?使用的连词?引导让步状语从句的连词主要有以下这些:thouｇh, ａlthｏｕgh，wｈiｌe, as； eｖen if, eｖｅn though； wｈeｔheｒ．..ｏr。.。；ｎo matter+疑 问词，疑问词－eｖer，regａｒdless oｆ+名词/名词 短语／名词从句,ｄespite，in spite of.切记alｔｈougｈ不可与bｕｔ连用 用法 （1)ｔｈough， although表示“虽然，纵然"之意。这两个连词意思大致相同，在一般情况下可以互换使用.在口语中，thoｕgh较常使用，alｔhouｇh比thｏugｈ正式，二者都可与ｙｅt，ｓtｉll或never，the less连用，但不能与but连用。 例如：Alｔhoｕｇｈ/Ｔｈｏuｇh ｈe ｗas ｅｘhａｕsｔeｄ, (stｉlｌ） he ｋept on worｋｉng。虽然他已经精疲力竭了,但仍然继续工作. (2)as， tｈoｕgｈ表示“虽然……但是",“纵使……"之意。 aｓ引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动

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. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，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和特殊的连接词即考点。现分别列举如下: 1．时间状语从句 常用引导词：when, as, while, as soon as, while, before, after, since , till, until 特殊引导词：the minute, the moment, the second, the instant, immediately , directly, every time, the day，no sooner …than, hardly …when, scarcely …when （1）Tell him I need to see him the minute he arrives. 他一到就告诉他我要见他。 （2）The children ran away from the orchard(果园) the moment they saw the guard.

She was standing exactly where you are standing now那时他就站在你现在站的地方。 Stay where you are.呆在原地别动。 Wherever you go, you should work hard. Sit anywhere you like 随便坐吧 3．原因状语从句
