江苏省南京市2018年中考英语语法复习 状语从句
中考语法状语从句1.定义和类型：用来修饰动词，副词和形容词的从句叫状语从句。
状语从句分类较多，中考常考的状语从句可分为1、时间状语从句2、让步状语从句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、比较状语从句（比较级已讲）2.具体分类：3.考点：①时间状语从句最常考的是until，常常和非延续性动词组合。
其次是结合进行时考察when/while/as，再次是结合主将从现考察as soon as/whenever.②原因状语从句，主要考察since作为既然的意思。
③目的状语从句，考察较少。
④结果状语从句常常考察so...that与such...that的辨析，so+many/few/much/little+名词结构用用的是so而不是such是一个重要考点。
⑤条件状语从句最常考的是unless，相当于if…not,意为“除非,如果不”。
其次结合主将从现考察if的用法⑥让步状语从句，主要考察句子的让步关系2016年一模真题组前瞻：2016年的一模试卷中考察了4个unless，1个though，1个since和1个before共7题。
首先，基本上每个区都有一题是关于连词使用的题目，由此可以看出状语从句的重要性。
其次，大部分区的题目都是考察了unless的用法，平常的复习中需要多加关注unless 表达的两句之间的关系。

高中英语语法专项—— 状语从句(九大状语从句详讲+配套练习)
语法专项2——状语从句【状语从句综述】由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。
一、时间状语从句1.表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。
例如：When I came into the office, the teachers were having a meeting.当我进入办公室时，老师们正在开会。
He started as soon as he received the news. 他已得到这个消息，就出发了。
Once you see him, you will never forget him.一旦你见了他，你就不会忘记他。
No sooner had I gone to bed than I went to sleep.我一上床就睡着了。
2.when, while, as的区别这三个词都可以用作连接词，表示时间关系，但有所区别。
(1)when表示时间关系时，意思常常是“当(在)……的时候”。
主句和从句中的动作或事情可以同时发生，也可以先后发生。
例如：When we were at school, we went to the library every day.我们在求学的时候，每天都到图书馆去。
(2)while 用作连接词表示时间关系时，意思也是“当(在)……的时候”，主句中的动作或事情在从句中的动作或事情的进展过程中发生。
它有时可与when通用，但它只能指一段时间(a period of time)，而不能指一点时间的(a point of time)。
中考英语语法专题 原因和让步状语从句讲解+练习
原因和让步状语从句一、原因状语从句用从句来表示主句行为或事件发生的原因，这个从句就是原因状语从句。
常用引导词：because, since, as, for1、because表示人们不知道的直接的原因或理由，着重点在从句；通常用于回答why引出的疑问句，语气最强；除特别强调外，该从句一般位于主句后面；不能与so连用但是可以与so进行同义句转换。
I didn’t go aboard with her because I couldn’t afford it.我没有和她一起出国是因为费用太高。
2、as和since引导的原因状语从句多表示大家众所周知的理由，从句多位于主句之前，since译为“既然”。
如：As I didn’t know the way, I asked a policeman. 我不认识路，因而问警察。
Since traveling by air is much faster, they decided to take a plane. 既然乘飞机旅行快得多，他们就决定坐飞机。
3、for表示的理由是附加的或推断的，并非此原因，通常与主句用逗号隔开，不位于句首，如：He must be not at home, for the telephone isn’t answered.练习（一）用because, as, since, for填空1. We’ll have to go to bed early ________ we’ll start off early tomorrow.2. ________ you know all about it, tell me please.3. ________ all the seats were taken, I had to stand.4. He must be at work, ________ the light in his office is still on.5. Lily didn’t go to school ________ she was ill.二、让步状语从句常用引导词：although, though “尽管虽然”1、两者通常可互换，在口语中，though较为常见。

〔二〕状从句解1.状从句引用法when意“当⋯的候〞。
