状语：表示时间、地点、结果、原因、目的的成分。（不是句子的必须组成）

状语从句：把状语变成句子。说明谓语动作的时间，地点，方式，手段，条件，程度，比较，原因，目的，结果等 I get up at six.

I get up when it is dark.

1. 时间状语从句:常用when, as, while, before, after, since, till, until, as soon as等连词来引导。

eg.While he was doing his homework, the telephone rang.

※ while 表示对比

While I was sleeping,the teacher came in. When the teacher came in,I was sleeping.

难点：以上 时间句+条件句 +主句祈使句 时态：主将从现 Eg: I will tell him everything when he comes back. I’ll help you with your English if I am free tomorrow. Let him call me as soon as he comes back

3.原因状语从句 常用：because, since, as引导 Eg.;He didn’t come to school because he was ill.

------Why aren’t going there?

------Because I don’t want to.

※ because和so不能同用在一个句子里。

4.结果状语从句由so…that, such…that, so that引导。

so + adj/adv+ that + 从句

5.比较状语从句 由as…as, 比较级 + than…等连词引导

6.目的状语从句由 so that, in order that引导。例如：
