初中英语语法——状语从句
状语从句一、考点解读今天我们复习状语从句，英语中状语与中文的状语大致相同，分为时间状语、地点状语、原因状语、目的状语、结果状语、条件状语、方式状语等等。
如果一个主从复合句中的从句是用来表示时间，原因等等时，那就称为状语从句。
在主从复合句中修饰主句中的动词、形容词、副词等的从句叫做状语从句，又由于其功能与副词非常相近，又称做副词性从句。
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、比较状语从句和方式状语从句九种。
这节课我们主要复习如下的内容：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．结果状语从句6．条件状语从句7．让步状语从句8．比较状语从句9．方式状语从句二、专题梳理（一）时间状语从句在句子中起时间状语作用的句子称为时间状语从句。
时间状语从句可以放在句首、句中和句尾。
常用来引导时间状语从句的引导词有：when 当……时候while 当……时候as 当……时候、一边after 在……之后before 在……之前since 自从ever since 自从once 一……就……whenever 不管什么时候by the time 到……as long as 长达……as soon as 一……就……till/until 直到……1．when，while，as的用法从属连词when，while，as都可用来引导时间状语从句，意为“在……时候”。
但在具体用法上又不尽相同。
（1）这三个连词中，when用得最广，常可代替while与as。
与while相比，when引导的从句动词既可是延续性的，也可是终止性的。
as在这一点上与when相同，while所引导的从句中，动词只能是延续性的。
在初中阶段，我们几乎很少讲as引导时间状语从句。
是因为as在初中阶段是一种供了解性的内容。
e.g.When the fire broke out, all the studentswere sleeping soundly.（终止性的）当火灾发生时，所有的学生正在熟睡中。

中考英语专项复习：状语从句归纳一、时间状语从句引导时间状语从句的连词有before、after、when、while、since (自从……)、till/until (到……为止)、as soon as (一……就……)、whenever (每当；任何时候)等。
1. 当主句是将来时或祈使句时，在before、after、when、till/until、as soon as等引导的从句中，用一般现在时。
如：I will call you as soon as I get to Beijing. 我一到北京，就给你打电话。
2. when引导的从句中，谓语动词可以是延续性动词，也可以是短暂性动词；while引导的从句中，谓语动词必须是延续性动词。
如：Things were different when I was a child. 我小时候的情况与现在不同。

4. 一般情况下till和until两者可以互换，但till不能放于句首。
结构如下：延续性动词+till/until...。
如果主句中的谓语动词是短暂性动词，该动词就要用否定形式，形成“not...till/until”结构，意为“直到……才……”。
如：Walk till / until you see a white house. 一直走到你看到一座白房子为止。
I didn’t go to bed until I finished my homework. 直到做完家庭作业，我才上床睡觉。

中考初三英语状语从句专题复习初三英语专题复习--状语从句专项练习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 work 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)。

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。

------Why aren't going there?------Because I don't want to.As he has no car, he can't get there easily.3 / 9Since we have no money, we can't buy it. (3)because和so不能同用在一个句子里。

其结构是:“...so+形容词（副词）+that +从句”。
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。
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 madesuch 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.4 / 9=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：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.5 / 9(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 hestill 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.【实例解析】1.
