在考研英语的备考中总不可避免地与各式各样的句式结构打交道，对于常规的英语句式结构，大多考生一般都能应对，但是对于一些比较特殊的结构（如强调结构、完全倒装结构、部分倒装结构等），可能会因为平时不太留心句子结构的细节或对英语中的一些特殊结构未进行过统一的整理和归纳等而在面对这些特殊结构时有时会无从下手。在这里华慧考研带大家一起来了解下考研英语中常见的几种状语从句。
状语从句
1.状语从句中以下四种从句考得较多，这里给予简单介绍。
1)时间状语从句
时间状语从句主要由以下连词引导：when,whenever,as,while,since,until,till,before,after,as soon as,once,hardly(scarcely)…when,no sooner…than。
I will discuss the matter with you when we meet tomorrow.
He didn’t go to sleep until he finished doing his homework.
You have changed a lot since we met last time.
时间状语从句还可由某些可充当连词的名词(the moment,the instant,every time,等)和副词(instantly,directly等)引导：
I will tell you the news the instant I know.
Directly the teacher came in everyone was quiet.
Note:
①before除了可表示“在…之前”外，还可用来强调主句所表达的时间、距离很长或花费的力量相比较大，可译为“…才”。(not…before可用来强调主句所表达的时间、距离很短或花费的力量相比较小，可译为“…就”)。
It was a long time before I got to sleep again.
They had not been married a month before they quarreled.
②如果位于when引导的分句之前的主句使用过去进行时、过去完成时或was/were about to,was/were on the point of等结构时，when表示突然发生某事，可译为“正在…突然”或“刚…就”等。这时，不能够用as或while来代替when。
I was walking on the street when I ran into my old friend John.
She had just fallen asleep when the telephone rang.
We were about to leave when it began to rain.
2)条件状语从句
条件状语从句主要由以下连词引导：if,unless,providing/provided(that),suppose/supposing(that),on condition(that),as/so long as,in case等。
So long as you work hard,you will surely achieve good results in examinations.
I shall return next Thursday unless something unexpected happens.
I will go provided that you go with me.
Please give this letter to John in case he comes.
3)让步状语从句
让步状语从句主要由以下连词引导：though,although,even if,even though,whatever,however,whoever,wherever,no matter how/what/where/when等。以下介绍几种较特殊的让步状语从句。
(1)while引导的让步状语从句多放在句首，while相当于although，表示“尽管”，“虽然”。
While I admit I did it,I didn’t intend to.
While I understand what you say,I can’t agree with you.
(2)短语even now/then/so相当于though it is/was true，表示“尽管如此”，“尽管这样”。
The fire was out,but even so,the smell of smoke was strong.
I’ve tried my best,but even now/then she is not satisfied.
(3)as引导的让步状语从句要倒装。
Child as he was,he could speak four languages.
Hard as she tried,she failed to get the job.
