状语从句指句子用作状语时，起副词作用的句子。它可以修饰谓语、非谓语动词、定语、状语或整个句子。根据其作用可分为时间、地点、原因、条件、目的、结果、让步、方式和比较等从句。状语从句一般由连词(从属连词)引导，也可以由词组引起。从句位于句首或句中时通常用逗号与主句隔开，位于句尾时可以不用逗号隔开。
二、知识讲解
知识点：
【考查点1】 让步状语从句
所谓让步，就是我们日常生活中“退一步说??”的意思，有一种转折关系在里面。引导让步状语从句的连词主要有以下这些：though, although,while, as; even if, even though; whether...or...; no matter+疑问词，疑问词-ever，一般翻译为“尽管??”或“即使??”，“无论??”。用法如下：
1、though, although表示“虽然，纵然”之意。这两个连词意思大致相同，在一般情况下可以互换使用。在口语中，though较常使用，although比though正式，二者都可与yet， still或never，the less连用，但不能与but连用。例如：
Although/Though he is very old, (yet) he is quite strong. 他虽然年纪大了，身体还很健壮。

值得注意的是，although引导的让步状语从句位于主句之前的情况较多，though引导的让步状语从句可位于主句之前或主句之后。
2、as，though表示“虽然??但是”，“纵使??”之意。as引导的让步状语从句必须以部分倒装的形式出现，被倒装的部分可以是表语、状语或动词原形，though也可用于这样的结构中，但although不可以这样用。例如：
Hard as/ though he works, he makes little progress. (=Though he works hard, he makes little progress.)尽管他学习很努力，但几乎没取得什么进步。
3、 even if, even though 表示“即使??”，“纵使??”之意，含有一种假设。 这两个复合连词的意思基本相同。它们常互换使用，但意义有细微差别。even if引导的让步从句含有强烈的假定性，可用来表示与事实相反的假设，但不能用来描述已经发生的事实。而even though引导让步状语从句时，是以从句的内容为先决条件的，即说话人肯定了从句的事实，表示已经发生了的事。例如：
We’ll make a trip even if/though the weather is bad. 即使天气不好，我们也要作一次旅行。 4、whether...or...表示“不论是否??”，“不管是??还是??”之意。由这一个复合连词引导的让步状语从句旨在说明正反两方面的可能性都不会影响主句的意向或结果。例如： You'll have to attend the ceremony whether you're free or busy. 不管你忙不忙，都要参加这个典礼 。
5、“no matter+疑问词”或“疑问词-ever”的含义为“??都??；不管??都??”它们引导的让步状语从句可以互换。例如：
No matter what happened, he would not mind. (=Whatever happened, he would not mind.)无论发生了什么，他都不会介意的。
但“no matter+疑问词”结构只能引导让步状语从句，而“疑问词-ever”还可以引导名词性从句。例如：Whatever (=No matter what) you say, I won’t believe you. (Whatever 引导让步状语从句)无论你说什么，我都不会相信你。
I'll eat whatever (≠no matter what) you give me. (whatever引导宾语从句)你给我吃什么，我就吃什么。

二、比较状语从句
比较状语从句一般是指含有比较级的句子中由as或than引起的从句。从某种角度上说，它也是一种方式状语从句，例如：
He moves more slowly than his sister does. 他行动起来比他妹妹慢。 He works as hard as his brother（does）. 他学习和他哥哥一样努力。 常见考法
对于让步和比较状语从句的考查，多以单选和完形填空的形式，从连词的意义角度让大家选择连词。 误区提醒
用though/although, as 引导让步状语从句时，句中不能用but表示转折语气。例如： 不能说：Though he looks weak, but he is healthy. 而要说：Though he looks weak, he is healthy. 或者说：He looks weak, but he is healthy.
