状语从句知识点详解（初中英语专项复习）状语从句的概念: 用一个句子作状语来修饰动词和形容词，以表明动作发生或状态存在的时间、地点、原因等，这个句子就叫做状语从句。
状语从句的分类：状语从句共分为九大类，包括：时间、地点、原因、条件、让步、目的、结果、方式、比较状语从句。
下面分别讲解：一、时间状语从句概念：用来表示时间的状语从句，由when, while, as, till, until，before, after, since等引导。
由于时间状语从句的引导词所表示的意思并非一致，不同引导词表达不同的时间，它们在句子中对应的时态、语态等也有所不同。
例如：when /while引导的时间状语从句when引导的从句的谓语动词通常是瞬间动词，也可以是延续性动词。
从句动作可与主语动作通常先后发生也可同时发生。
I was writing when my sister came back.( come是瞬间动词，只能用when引导，不能用while)He often wrote me when/while he studied in Shanghai International Studies University.( study 是延续性动词，while可代替when)While my mother was cooking , I was playing chess with dad. (cook是延续性的动词，cook和play同时发生)I like playing chess while my sister likes reading stories.我喜欢下棋，而我姐姐喜欢看小说。
(while表示对比)when和while的区别还有：while引导的时间状语从句多用于进行时态，而when引导的时间状语从句多用于一般时态。
While we were playing games, our headmaster called me .我们正在做游戏的时候，校长叫我了。

八种状语从句
八种状语从句状语从句在句中作状语，修饰主句中的动词、形容词和副词等。
按其作用和意义可分为时间、原因、目的、结果、条件、让步、方式、比较八种。
下面对这八种从句的要点加以总结。
一、各类状语从句的引导词及易混词的区别。
1. 时间状语从句1) 引导词（1）表示“当……时候”：when, while, as, whenever（2）表示“一……就……”：as soon as（3）其它：after, before, since, until, by the timeWhenever he comes, he brings a friend. 他每次来都带个朋友。
I want to see him as soon as he arrives. 他一来我就要见他。
I went to bed after I finished my homework. 我做完家庭作业之后才睡觉。
2) 易混引导词when, while, as 的区别when既可指“时间点”，与瞬时动词连用，也可指“时间段”，与延续性动词连用（这时可与while互换）。
如：When he came in, his mother was cooking. 他进来时，他妈妈正在烧饭。
When（While）we were at school, we went to the library every day. 我们在校求学时，每天都到图书馆去。
while 只表示时间段，因此while从句的谓语动词要用延续性动词。

as 与when 用法相似，但着重强调主句动作与从句动作同时发生，有“随着……”或“一边……一边……”之意。
She sang as she went along. 她边走边唱。
As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。

原因状语从句与结果状语从句的区别
原因状语从句与结果状语从句的区别原因状语从句和结果状语从句是复合句中常见的两种从句类型，它们用于表示动作或事件之间的因果关系。
尽管它们的作用相似，但是在使用和表达上存在一些区别。
本文将详细探讨原因状语从句与结果状语从句的区别。
一、原因状语从句原因状语从句用于表示某个动作或事件的原因，或者引导由原因引起的结果。
原因状语从句通常由连词“因为”、“由于”、“由”等来引导。
以下是一些例子：1. 因为下雨，所以我带了伞去上班。
2. 由于他没有学习，所以考试不及格。
3. 他迟到了，由此引起老师的不满。
4. 他思考了很久，因而做出了明智的决定。
从上述例子可以看出，原因状语从句一般位于主句之前，因为它们是表达动作或事件的原因，需要先进行说明。
另外，原因状语从句中的主谓结构完整，与主句独立存在，即使没有主句，也能够完成一个完整的句子。
二、结果状语从句结果状语从句用于表示某个动作或事件的结果或后果，或者引导由某个原因产生的结果。
结果状语从句通常由连词“以致于”、“以至于”、“结果”等来引导。
以下是一些例子：1. 他准备得很充分，结果获得了第一名。
2. 天气太冷了，结果我们决定取消野餐。
3. 他努力学习，以致于考试取得了好成绩。
4. 他为了赶火车，结果摔倒了。
与原因状语从句不同，结果状语从句一般位于主句之后，因为它们是描述动作或事件的结果，需要在主句之后进行说明。
与原因状语从句类似，结果状语从句中的主谓结构也是完整的，独立存在的。
三、区别与联系尽管原因状语从句和结果状语从句都是表示因果关系的从句类型，它们在使用和表达上存在一些区别。
首先，位置不同。
原因状语从句一般位于主句之前，而结果状语从句一般位于主句之后。
其次，引导词不同。
原因状语从句常用连词“因为”、“由于”等引导，而结果状语从句常用连词“以致于”、“以至于”等引导。
再次，表达形式不同。
原因状语从句通常表达一个动作或事件的原因，因此强调原因之间的因果关系。
而结果状语从句则表达一个动作或事件的结果，强调结果与原因之间的联系。
