状语从句
1. 在主从复合句中修饰主句中的动词，形容词，副词等的从句叫状语从句。可分为，时间状语
从句，地点状语从句，原因，目的，结果，条件，让步，比较和方式状语从句。
2. 时间状语从句
起时间状语作用的句子；可放在句首，句中和句尾
常用引导词：when，while, as, after, before, since, till, until, the moment, hardly … when , no sooner … than
when, while, as的用法
1) when 用法最广，常可代替while和as, 在while 引导的从句中，动词只能是延续性的
When the fire broke out, all the students were sleeping soundly.
The telephone rang while I was taking a bath.
2) 当两个表示时间延续的动作同时发生而又有对比意味的时候，用while，在这样的复合
句中，主句从句的时态通常是相同的。
Father was preparing a report while I was playing PC games.
3) 常用as的情况：一边…一边；表示随着短暂动作的发生，另一行为伴随发生
As he talked on, he got more and more excited.
They talked as they walked along the river.
My cap was blown away as I sat down.
until和till的用法
表示“一直到…”时，主句和从句都用肯定式；
I will wait until/ till the concert is over.
表示“直到…才…”是，主句用否定，从句用肯定式。They can’t go until Sunday.
since的用法
He has written to me frequently since he was ill. 自从他病好以来，他常写信给我。
主将从现。时间状语从句一般不用将来时。因此如果主句是将来时，时间状语从句一般
要用现在时。
We’ll start when the team leader comes.
一…就…的几种常用的表示方法
1） as soon as
As soon as he heard the news, he jumped with joy.
2） Immediately
I’ll give you an answer immediately I’ve finished reading your file.
3） Directly
Directly you feel any pains, you must go to the doctor.
4） Instantly
Please give me a phone call instantly you arrive.
5） no sooner than
No sooner had I begun to talk than he rang offl
I had no sooner begun to talk than then he rang off.
6）hardly…when
Hardly had I told him my name when he stopped listening.
I had hardly told him my name when he stopped listening.
3. 地点状语从句
引导词where, wherever, anywhere, everywhere, nowhere
一般情况下，只要在where前面加上to/in/from the place，就可以变为定语从句
We live where the road crosses the river.
We live in a place where the road crosses the river.
4. 原因状语从句
引导词：单词—because，as, since 短语—now that, for the reason that, in that, seeing that Because, as, since, for
1）because 的语气最强，用以回答why 引起的提问，可表示已知或未知的世事。可与only ,merely, just ,not 连用，所引导的从句常用于主句之后，在表示强调的时候可置于主句之前（可用于强调结构）
He was punished only because he broke the law.
It was because that I went to town yesterday.
2）as 的语气最弱,不可用于强调，常至于主句之前。
As he was in a hurry, he left this bag home.
3）since的语气也比较弱,常表示对方已知的事实，往往相当于汉语的既然。不用于强调。
常置于主句之前。
Since she can’t answer this question, it is better to ask someone else.
4）for连接并列句
We should be more careful, for it is already dark.
now that
用于口语，表示较弱的原因，主从句因果关系不明显。既然，that可省略。
Now（that）you are grown up, you should not rely on your parents.
for the reason that
后跟一个同位语从句。
in that
This experience is worth trusting in that it is based on scientific facts.
when（既然）
I can’t tell you anything when you won’t listen.
How can he succee d when he won’t work?
5. 目的状语从句
in order that /so that
I hurried through my work in order that I could be in time for wonderful TV programs.
for fear that
I’m working hard for fear that I should fail.
in case I stayed all day at home in case you called.
6. 结果状语从句
so that so + 副词、形容词+that
The text was so boring that I fell asleep.
so+ many/few/much/little+that
He has got so little money that his family had to live on welfare.
such + a + 形容词+可数名词单数、复数+that
It was such a terrible day that none of us would find an excuse for going out to play.
They are such good children that we all love them.
such+形容词+不可数名词+that
This was such fine music that it was worth listening to twice.
7. 条件状语从句
引导词：if, unless, as/so long as, once, in case, on condition that, supposing (that), providing (that), provided (that), given (that) 写作的时候，学会在文章里添加几个状语从句。
Providing/Supposing/Given/Provided that you promise not to tell anyone else, I’ll explain the secret.
In case it rains, do not expect me. 如果下雨，就不要等我了。
真实条件句与非真实条件句
Unless you go at once, you will be late.
If we had enough time yesterday, we could have done the work.
其实属于一种虚拟语气。第一种是真实条件句，表示可以实现，第二句是非真实条件句，实现的可能性不大。
8. 让步状语从句
Though和although 基本相同，但是though可以当副词，although不可以
Young though she is, she has travelled to many countries to put on shows.
I’ve bit of headache. It’s nothing much, though.
Even though 和even if
Even though the learning is slow and painful, the result is wonderful.
Even if/ though you say so, I do not believe.
As Pop star as she is, she still needs to improve.
Fail as I did, I would never give up.
whether (…) or not 和whether … or …
wh-ever类的用法
引导名词性从句，只能用wh-ever，不能用no matter wh-
I’ ll wait for you however late it is. = I’ll wait for you no matter how late it is.
9. 比较状语从句
As…as not as/ so … as , than , the +比较级，the+ 比较级
His handwriting is not as good as yours (is).
The sooner you are back, the better it will be.
10. 方式状语从句
As 正如，像
Will you please do the experiment as I am doing.
as if 和as though
(1) 如果表述内容可能性很大，则用陈述语气look/seem/taste /smell 等词连用
It looks as if it is going to rain.
(2) 表述的不是事实，则用虚拟语气
The young man with long hair looks as if he were a girl.

高考英语状语从句八类常考考点 状语从句是高考英语的必考考点，综观近年来各省市状语从句的考题情况，我们发现以下八类状语从句特别值得关注： 一、in case引导的状语从句 根据语境的不同，in case既可表示“如果”“万一”，引导条件状语从句；也可表示“以防(万 一)”，引导目的状语从句。下面两道真题均选in case： 1. Leave your key with a neighbor ______ you lock yourself out one day. (北京卷) A. ever since B. even if C. soon after D. in case 2. My parents live in a small village. They always keep candles in the house ______ there is a power cut. (重庆卷) A. if B. unless C. in case D. so that 【解析】两道题都选in case，均表示“以防万一”。 二、before引导的状语从句 尤其要注意“it+be+一段时间+before…”这一句型。如： 1. The field research will take Joan and Paul about five months; it will be a long time ______ we meet them again. (安徽卷) A. after B. before C. since D. when 2. He was told that it would be at least three more months ______ he could recover and return to work. (江西卷) A. when B. before C. since D. that 【解析】两道题均before。第1题涉及的句式为：It will be a long time before…，意思是“要过很久才会……”；第2题涉及的句式为：it was some time before…，意思是“在……之前过了一段时间”，通常可转译为“要过一段时间才会……”。 三、while引导的状语从句 尤其要注意while表示“尽管”“虽然”时的用法（此时它引导的不是时间状语从句，而是让步状语从句——此用法许多同学并不熟悉，值得特别注意！）。如： ______ I really don’t like art, I find his work impressive. (山东卷) A. As B. Since C. If D. While 【解析】答案选D。while在此表示“尽管”“虽然”，又如：While the work was difficult, it was interesting. 尽管工作有难度，但很有趣。/ 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。 另外，while表示对比的用法也值得注意（此时它表示“而”）。如： The cost of living in Glasgow is among the lowest in Britain, ______ the quality of life is probably one of the highest. (天津卷) A. since B. when C. as D. while

专题十一状语从句 状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。状语从句 1. 时间状语从句 常见的连词(组)： when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。 可以引导时间状语从句的副（介）词（短语）或名词短语： directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。 注意点如下： (1) when, while, as引导的时间状语从句 as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。 She came up as I was cooking.(同时) 在我做饭时，她走了过来。 When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。 While they were watching TV, I was preparing myself for the coming examination. 他们在看电视，而我在为即将到来的考试做准备。 Strike while the iron is hot. 趁热打铁。( 不可用as或when，这里的while意思是“趁……”) (2) before引导状语从句时的常见重点句型 ①It will (not) be ...before ... 还要……才，要不了多久就…… It was (not) ...before ... 过了……才(没多久就……) It was a long time before I got to sleep. 过了好长时间我才睡着了。 It wasn t long before he told me about the news. 没多久他就告诉了我那条新闻。 ②不等……就……；在……之前就…… The telephone rang off before I could answer it. 我还没来得及接电话，电话就挂断了。 ③刚……就…… He hardly entered the room before he heard the telephone ring. 他刚进屋电话铃就响了。
