语法专题十四、状语从句（必考）一个句子做整句话的状语，这个句子就叫做状语从句。

状语从句根据从句在整句中表示的含义不同又可细分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句、让步状语从句、比较状语从句、方式状语从句等。

接下来我们重点复习几类状语从句。

一、时间状语从句定义和特征英语里如果用从句来表达一件事情或者一个动作发生的时间，那么这个从句就叫时间状语从句。

时间状语从句通常由when, while, as, before, after, since, as soon as, till/until等词引导。

【特征】含有时间状语从句的复合句，如果主句用一般将来时，从句用一般现在时表示将来。

（主将从现）(2021·全国·单元测试)—Daddy, when will we go out to fly a kite？—As soon as the rain _____．A. is stoppingB. stoppedC. will stopD. stops【答案】D【解析】句意：——爸爸，我们什么时候出去放风筝？——雨一停下（我们就去）。

as soon as 一……就……，引导时间状语从句，主句用一般将来时，从句用一般现在时。

故选D。

几种常见时间状语从句。

1.when引导：when表示“当……时候”。

既可表示在某一时间点发生的事，又可表示在某一时间段发生的事。

主句与从句描述的动作或事情可以是同时发生，也可以先后发生。

✧When I got home, I found my baby girl singing in the living room.当我到家时，我发现我的小女儿正在客厅里唱歌。

✧Things were different when I was a child.我小时候情况与现在不同。

【注意】when从句中的谓语动词可以是延续性动词，也可以是短暂性动词。

专题11 状语从句概念：指的是在主从复合句中作状语的从句，修饰主句中的动词、形容词或副词等。

状语从句由从属连词引导。

状语从句放在主句之前时，常用逗号分开；若放在主句之后，一般不用逗号。

基本分类：1.时间状语从句：When Susan goes to town, she will visit her grandma.2.条件状语从句：If he works hard, he will surely succeed.3.结果状语从句：Waste must be treated so that it does not become a danger to life.4.目的状语从句：They worked hard in order that they might succeed.5.原因状语从句：Mary didn't go shopping because I advised her not to.6.让步状语从句：Though we are all different, we need never be separate.7.比较状语从句：I was happier than I had ever been in my life.8.地点状语从句：I will go where I am needed.9.方式状语从句：I have changed it as you suggest.考点一：让步状语从句(1)让步状语从句通常由although, though 等连词引导。

例如：Though he is young, he knows a lot.Although I am tired, I must go on working.注意：although 只能用在句首，而though 既可以放句首也可以放句末。

(2)although(though)不能和but 用在同一个句子中。

例如：Though it was raining hard, but he still went out. （╳）应该说：Though it was raining hard, he still went out.或It was raining hard, but he still went out.考点二：时间状语从句时间状语从句常用when, as, while, before, after, since, till, until, as soon as等连词来引导。
