状语从句
状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔
开。
1. 时间状语从句
(1)时间状语从句常用when, as（当..时候）, while, before, after, since, till, until, as soon as等连词来引导。例如：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，主句用将来时态时，从句通常不用将来时态，用现在时态表示将来的动作或状态。（主将从现）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……”, 谓语动词可用瞬间性动词。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(除非)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。（主将从现）例如：（必考）
I’ll help you with your English if I 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。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.
(2)so…that与such...that可以互换（可能会考）。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：
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.
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（否定not so/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.
6. 目的状语从句
(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)与but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.
易混引导词
while, when的区别：
既可以指"时间点",与瞬间动词连用，也可以指"时间段"，与延续性动词连用（=while）。如：
When he came in, his mother was cooking.
When (While) we were at school, we went to the library every day.
While表示时间段,因此，while 从句的谓语动词要用延续性动词。如：
Please don't talk so loud while others are working. 2．Because,as,since 的区别：
Because用于表示直接原因,回答why提出的问题，语气最强；As用于说明原因, 着重点在主句，常译成"由于"；since表示显然的或已知的理由或事实，常译成"既然"。如：
Water is very important because we can't live without it.
He didn't come yesterday as his mother was ill.
I'll do it for you since you are busy.

时间状语从句 要点: 时间状语从句，由以下连词引导： when while as after before as soon as since till /until by the time 在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。 当。。。的时候 mozart started writing music when he was four years old. (当)莫扎特的时候，开始写音乐作品。 当。。。时 he visited a lot of places while he was traveling.他在旅途中参观了许多地方。 在。。。的同时；一边。。。一边。。。 he smiled as he stood up.他一边站起来一边笑着。 在。。。之后 he left the classroom after he had finished his homework the other day. 前几天做完作业之后回的家。 在。。。之前 mr. brown had worked in a bank for a year before he came here. 布朗先生来这之前已经在一家银行里工作一年了。 soon as 一。。。就。。。(主将从现) we began to work as soon as we got there.我们一到那就开始工作。 i will write to you as soon as i get home.我一到家就给你写信。 自。。。以来到现在 表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。 mr green has taught in that school since he came to china three years ago. 自格林先生来中国以来，他就在这所学校教书。 (还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。) 8 till /until都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。 they walked till /until it was dark.他们一直走到天黑。 xiao ming didn’t leave home till / until his father came back.小明直到他爸爸回来才离开家。 9. by the time 到。。。为止 (所在句子的主句应用完成时) by the time he gets there , his father has already gone.他到家的时候，他爸爸已经走了。 by the time i got to school, the class had already began.我到校时，已经开始上课了。 难点——as when while的辨析 as when while都表示主、从句动作同时发生，三者差异如下： as 表示“一边。。。一边＂的意思 强调两个动作同时进行，并表示对比时 when 1、还可以表示从句动词的动作在主几句动词的动作＂之前＂或＂之后＂发生。 2、when＝and then; at that moment (正在那个时候)
中考英语状语从句考点归纳与例析 【重点讲解】 中考英语试题对状语从句的考查主要涉及引导状语从句的从属连词的用法。单项选择题的四个选项往往是四个连词，这是状语从句最常见的考查形式。另一个考点是状语从句中的时态，因此，在学习状语从句时要弄清状语从句的几个主要类别，如时间、地点、原因、条件、让步、方式、目的、结果等，同时记住它们的“引导词”及其相关意义。 考点一：引导状语从句的连词的选择。 1、引导时间状语从句的连词主要有when, while, as, by the time, before, after, since, till/until, as soon as等。其中when，while和as都可表示"当……时候"，但用法有区别: when意为"在……时;当……时",可表示"点时间"或"段时间",从句谓语可以是终止性动词,也可以是延续性动词。例如: When I got home, he was having supper. as意为"边……边……"或"与……同时",重在表示两个动作同时发生。伴随进行。as从句是终止性动词时,主句通常也必须是终止性动词。例如: They sang as they danced. while只可表示"段时间",从句谓语只限于延续性动词。例如: While I was sleeping, my father came in. 注意：从句谓语是持续性动词时,when，while和as可以互换。主、从句谓语都是终止性动词时，when与as可互换。从句谓语表示状态时，通常用while。 2、引导地点状语从句的常用连词是where。例如： Where there is a will there ia a way. 3、引导原因状语从句的连接词主要有because, as, since, for。例如： Tom was late for school this morning because he didn’t catch the early bus. As he was not well,I decided to go there without him. Since this method doesn't work, let's try another. for表示所说的理由是一种补充说明，因此, for引导的从句一般不放在句子的开头。例如: I decided to stop and have lunch, for I was feeling quite hungry. 注意：because语气最强，as, since, for次之。对于以why开头的问句，一般要用because引导的从句来回答。 4、引导条件状语从句的连接词主要有if, unless, as long as。例如： If I am not busy tomorrow, I will play football with you. Unless you tried it, you can’t imagine how pleasant it is. 5、引导让步状语从句的连接词有although, though, even if, even though。例如： Although (though) I gave him some advice, he didn’t take them.
【英语】初中英语状语从句试题经典 一、初中英语状语从句 1． the journey was tiring，Jeff thought it was worth both the time and the money. A．As B．Since C．Unless D．Although 【答案】D 【解析】 【详解】 句意：虽然旅途很累，杰夫认为时间和金钱都值得。 A. As当……的时候； B. Since 自从； C. Unless除非； D. Although尽管。根据下文Jeff thought it was worth both the time and the money.可知上文是让步状语从句，这里用Although引导。根据题意，故选D。 2．-- Can’t I park my car free here? -- You can, for four hours, __________ you spend over 100 yuan in this supermarket. A．though B．if C．unless 【答案】B 【解析】 【详解】 句意：-我不能把车免费停在这里吗？- 如果你在这家超市花费超过100元，你可以免费停车四个小时。though 虽然；if 如果；unless 除非。这里是形容一种条件，如果消费超过100元，就能免费停车，故选B。 3．My English teacher has taught English she came to the school. A．since B．as C．when D．for 【答案】A 【解析】 【详解】 考查连词辨析，句意：我的英语老师自从来到这个学校就教英语．结合语境推断句意是"我的英语老师自从来到这个学校就教英语．"，此句中的谓语动词用了现在完成时，本题设空处后面的时间状语从句用了一般过去时，所以结合句意用现在完成时的标志词since引导，故选A 4．He made a serious mistake, but he took immediate action to change that ______ it got worse.

初中英语状语从句知识点总结（一） 用来修饰主句中的动词，形容词或副词等而充当状语的从句叫做状语从句。状语从句常用从属连词来引导，与主句连接起来。若置于句末，则前面不加逗号。根据意义和作用，状语从句可分为时间原因条件等几种。下面我们就来分析一下这几种状语从句。 1时间状语从句 时间状语从句常用从属连词when,after,until,as soon as,等来引导。 当主句是祈使句或谓语动词是一般将来时态或情态动词时，其时间状语从句中的谓语动词常用一般现在时态表示将来发生的动作或存在的状态。这就是我们常说的“主将从现”。 如：Please call me when you get there.当你到那时，请给我打个电话。 I will write to you as soon as I arrive in Beijing.我一到北京就给你写信。 <温馨提示>since引导时间状语从句表示“自从…以来”，从句中的动词一般表示动作的起点，用过去时;而主句的动作延续的情况则用一般现在时或现在完成时。常用的句型为： It has been/is+一段时间+since+过去时。 如：I has been/is three years since we met last time.自从我们上次见面，已经三年了。 2条件状语从句 引导条件状语从句的连词或词组有：if(如果),unless(除非),as long as(只要)等。如果主句是将来时，条件状语从句也用一般现在时来表示。 如：I will stay at home if it rains tomorrow.如果明天下雨，我就待在家。 You can’t learn English well unless you wo rk hard. 除非你努力学习，否则是学不好英语的。 <温馨提示>由if引导的条件状语从句，若从句表达的是与现在事实相反的事实，则常用虚拟语气，即用过去时态表示(如果涉及到be动词，一律都用were)。此时，主句则用过去将来时。
