在复合句中修饰主句中的动词、形容词或副词， 起状语作用的从句叫状语从句。状语从句可置主语之 前，也可置主语之后。前置时，从句后用逗号与主句 分开；后置时，与主句之间无标点符号。 状语从句可分为时间、原因、目的、结果、条件、 比较、地点、让步、方式等九类。
1.时间状语从句 (1)引导词：when,while,as,before,after, as soon as,until,since. (2)主句为将来时，从句用一般现在时代替。 (3)not...until的同义句替换。 2.条件状语从句 (1)引导词：if,unless. (2)主句为将来时，从句用一般现在时代替。 (3)if...not与unless及or的同义句转换。
3.原因状语从句 (1)引导词:because, since, as. (2)对because 原因状语提问用“why”。 (3)because 不能与so连用。 (4)because,since，as,for的区别： because 从句所表示的是对方不知道的直接的原因， 因此在回答以why引导的特殊疑问句时只可用 because,而as,since 引导的从句却不可；as， since从句所表示的往往是对方已知的原因；for往 往用于附加理由证明。
4.目的状语和结果状语 (1)引导词：so that.从句中常用情态动词。 (2)结果状语从句引导词：so...that,such...that. (3)so与such的区别 ①so+形+a/an+名 such+a/an+形+名 ②so+many/much/few/little+形+名 ③such+形+不可数名词/可数名词复数 (4)so...that与too...to和...enough to间转换
5.比较状语从句 (1)引导词：as...as,not as (so)...as,than (2)not as (so)...as与than的同义句替换。 (3)as...as,not as (so)...as中间用形容词或副词的 原形。 6.让步状语从句 (1)引导词：though,even though. (2)though不能与but连用。 7.地点状语从句 (1)引导词where,wherever. (2)wherever=no matter where 8.方式状语从句 引导词：as if,as though.
