状语从句在复合句中作状语，修饰动词、形容词或副词等。状语从句可以表示时间、条件、原因、地点、目的、结果、让步、方式、比较等意义。 知识梳理：提纲挈领，抓住重点和难点！ 各类状语从句连接词（短语）一览表：

原因 As, because, since，as/so long as(既然,因为) 地点 Where

方式状语从句：

The work isn't as easy as I thought.这项工作比我想象得难。 例题解析：举一反三，学的更轻松！ 1. 易混引导词while, when, as的区别：
when可以和延续性动词连用，也可以和短暂性动词连用；而while和as只能和延续性动词连用。如： When he came in, his mother was cooking.
When (While) we were at school, we went to the library every day.
when从句的谓语动词可以在主句谓语动作之前、之后或同时发生；while和as从句的谓语动作必须是和主句谓语动作同时发生。
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.
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。如：
As you get older, you get more knowledge.随着年龄的增长，你获得的知识就越多。
在将来时从句中，常用when，且从句须用一般时代替将来时。
①You shall borrow the book when I have finished reading it．在我读完这本书后，你可以借阅。
②When the manager comes here for a visit next week，Ill talk with him about this．下周，经理来这参观时，我会和他谈谈此事。
when用于表示“一……就……”的句型中（指过去的事情）。
sb．had hardly（＝scarcely） done sth．when．．．＝Hardly ／ Scarcely had sb．done sth．when．．．
①I had hardly ／scarcely closed my eyes when someone knocked at the door．＝Hardly ／ Scarcely had I closed my eyes when someone knocked at the door．我刚一闭上眼，就有人在敲门了。
②I had hardly ／scarcely entered my room when the telephone rang．＝Hardly ／Scarcely had I entered my room when the telephone rang．我刚一走进房门，电话就响了
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.
3．such…that, so…that, so that 引导结果状语从句的区别：
such是形容词，修饰名词; so 是副词，修饰形容词或副词。其结构如下： 1) such + a (n)+ 形容词+单数可数名词+that……
2) such+形容词+复数可数名词+that …… 3) such +形容词+不可数名词+that……。如：
This was such a good film that I went to see it several times. It was such good books that they sell well. It was such bad weather that I had to stay at home. He spoke so fast that I couldn't follow him. He is such a lovely boy that we all like him. =He is so lovely a boy that we all like him.
注：在\形容词+可数名词复数/不可数名词\结构中，当名词前有many, much, few, little表示数量的多少时，名词前用so。如：
She made so many mistakes that she didn't pass the exam. so that 既可以引导目的状语从句又可以引导结果状语从句
引导目的状语从句时可译为\为了\引导结果状语从句时可译为\以便\如I speak loudly so that all the students can hear me clearly.(目的状语从句) Maria likes the woolen dress so that she decides to buy it immediately .(结果状语从句) (1) so that引导目的状语从句时表示“以便为了”从句中常使用can /could /may /might /will /would /should等情态动词或助动词引导结果状语从句时从句中一般不用can和may等词。
(2) So that引导的目的状语从句之前不用逗号而so that引导的结果状语从句与主句之间往往有逗号相隔开即略作停顿意思是“因此;所以”。请比较 He worked hard at his lessons so that he could gain high grades in the exams.他努力学习功课取考试能获得好成绩。
He worked hard at his lessons, so that he gained high grades in the exams.他努力学习获得了好成绩。
