状语从句
状语从句用来修饰主句中的动词，副词和形容词的从句叫状语从句。根据其含义状语从句可分为时间状语从句，地点状语从句，条件状语从句， 原因状语从句，结果状语从句，比较状语从句，目的状语从句，让步状语从句。
时间状语从句
一、关于时间状语从句的时态
1.主句一般将来时，从句用一般现在时 (主将从现)
例如：The by will be writer when he grws up.
2.主语含有情态动词，从句用一般现在时(主情从现)
例如：When the lights are red, the traffic must stp.
3.主句为祈使句，从句用一般现在时(主祈从现)
例如： Please dn’t g t bed befre yu finish yur hmewrk.
4.主句为一般过去时，从句也用过去时态(主过从过)
例如：I liked reading when I was yung.
引导词
（时间状语从句常用when, as, while, befre, after, since, till, until, as sn as等连词来引导。）
1.when, while,as引导的时间状语从句的
when和while与过去进行时有着密切的关系，他们作从属连词时都有“当…….时候”之意，
用法稍有不同：
①when引导的从句: 表示主句的动作和从句的动作同时发生, 或从句的动作发生在主句动作之前。
②when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。
③as引导的时间状语从句: 由as引导的时间状语从句, 表示“ 一边……一边……, 随着……”。其从句的主语与主句的主语往往是同一人或物。例如：
(1)I was playing cmputer games when my father gt hme.
= When my father gt hme,I was playing cmputer games.
(2) Mther was cking when/while I was ding my hmewrk.
= When/While I was ding my hmewrk, mther was cking.
He hurried hme, lking behind as he went. 他匆匆回家，一边走一边回头看。
As time ges by, I like China better.随着时间的推移，我更喜欢中国。
2.until和till引导的从句:
①表示“直到……为止”, 主句和从句都用肯定式till和until都可以。
(固定组合里frm mrning till night，till/until是不能替换的)例如:
They wrked until/till it was late. 他们一直工作到天黑。
②表示“直到……才”, 主句主句动词是瞬间动词，主句用否定式, 从句用肯定式。例如:
She didn’t g t bed until she finished her hmewrk. 她一直到写完作业才睡觉。
3.befre引导的从句: 一般表示主句的动作发生在从句动作之前。例如:
I didn’t knw any English befre I came here. 我到这儿来之前, 一点英语都不懂。
4.after引导的从句: 表示主句的动作发生在从句动作之后。例如:
After he lcked the dr, he left. 他锁上门, 就走了。
since引导的从句:
表示“自从……以来”, 从句中的动词一般表示动作的起点, 用一般过去时；主句中的动词表示动作延续的情况, 一般用现在完成时。如果主句中的动词表示的不是延续的动作而是表示目前的状态, 可用一般现在时。例如：
She has taught in this schl since she came t this city in 1989. 自从她1989年来到这个城市以来，她一直在这所学校教书。
it’s+时间+since 从句
例如：
It’s three years since she came t this city. 她来这个城市已经三年了。
5.as sn as引导的从句: 表示“一……就”, 强调动作紧密相连。
例如:
As sn as I arrive in Shanghai, I’ll write t yu. (主将从现)我一到上海，我就给你打电话
As sn as she came t the classrm, she began t read English. 她一到教室, 就开始读英语。
原因状语从句
在句中用来说明主句原因的句子叫作原因状语从句。通常由because, since, as，fr引导。
（1）because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。
------Why aren’t ging there? ------Because I dn’t want t.
I did it because he tld me t.
（2）Since和nw that语气比because弱，常翻译为“既然”一般用来表示明显的原因。由since引导的原因状语从句多放在句首。
Since we have n mney, we can’t buy it.
Nw that yu are busy, let me d it fr yu.
（3）as语气比since弱，表示附带说明的 双方已知的原因，含有对比说明的意味。
As he has n car, he can’t get there easily.
（4）fr引导的，不说明主句行为发生的直接原因，只提供一些辅助性的补充说明，并且只能放于主句之后.
We must start early tmrrw, fr we have a lng way t g.
It must be mrning fr the birds are singing.
目的状语从句
用来补充说明主句中谓语动词发生的目的的状语从句。
(1)目的状语从句通常由 s that, in rder that（为了，以便）引导。例如：
We started early s that we culd catch the first train.
We used the cmputer in rder that we might save time.
(2) 目的状语从句的谓语常含有may ,might , can , culd , shuld , wuld 等情态动词
结果状语从句

经常由s…that, such…that, 引导。
（1）在由引导的结果状语从句中，s是副词，与形容词连用。
... s + 形容词（副词）+ that…
+ 形容词+ a/an + 可数名词单数+that...
He was s glad that he culdn’t say a wrd.
It was s ht a day that we all went swimming.
(2)由such…that引导的结果状语从句中，such是形容词

such+形容词+可数名词复数/不可数名词+ that
It was such a ht day that nbdy wanted t d anything.
He had such lng arms that he culd almst tuch the ceiling.（天花板）
有时上述两种结构是可以互换的。例如：
It is such an imprtant match that nbdy wants t miss it.=The match is s imprtant that nbdy wants t miss it.
(3)如果名词前由many, much, little, few等词修饰时，只能用s, 不用such。例如：
Sn there were s many deer that they ate up all the wild rses.
He has s little time that he can’t g t the cinema（去看电影） with yu.
结果状语从句
结果状语从句的从句部分是补充说明主句中谓语动词发生的结果的，通常位于主句之后。结果从句中通常不用情态助动词，但must,can,culd除外。such用在（形容词）名词之前；而s要用在形容词/副词之前，s或that有时会省略掉。以下逐一介绍中考中常见的引导结果状语从句的词：
1. s that可以引导目的状语从句， 也可以引导结果状语从句。
例如：

if引导的条件状语+表示禁止做某事的结构

如果你来北京，一定要顺便拜访一下我。

N shuting.请勿喧哗。
(2)N+名词

条件状语从句
条件状语从句就是用以表示“在某种条件下，会……”，引导词主要有 if, unless, as/s lng as, n cnditin that, prvided, suppse, suppsing 等..
主句用一般将来时，if或unless引导的条件状语从句用一般现在时。
