定义 状语从句是指在句子中用作状语、起副词作用的句子，修饰谓语、非谓语动词、定语、状语或句子。
连接词：when, while, as, befre, after, until/till, since, as sn as, by the time
连接词: because, since(因为，既然), as, fr
fr连接的并列句分句前常有逗号，其引导的分句不可放于句首。 例：It must have rained last night, fr the grund is still wet.
【注】because不能与s同时使用。
2.遵循“主将从现，主祈从现，主情从现”的原则
1.连接词：if, unless, as lng as(只要)
e.g. If I am free, I will call yu.
e.g. We shall g there tmrrw unless it rains. = We shall g there tmrrw if it desn’t rain.
e.g. Yu will succeed as lng as yu wrk hard.
连接词：s that, in rder that
E.g. Speak slwly s that/in rder that we can understand yu.
s that和in rder that后常接含can/culd, may/might, shall/shuld, will/wuld等情态动词的从句
如果目的状语从句的主语与主句的主语相同，可用in rder t 转化为简单句。
E.g. I’ll write dwn yur phne number s that I may nt frget. = I’ll write dwn yur phne number in rder nt t frget.
连接词：s that, s… that…, such …that…
名用such，形、副s，多多少少也用s。
s…that与such…that的区别
总结: ① s +形容词/副词+that… s+形+a/an+名(单数)+that… such+a/an+形+名(单数) +that… ② 用s不用such: s+many/much/few/little+形+名 ③ 用such不用s: such+形+不可数名词/可数名词复数
s…that…引导的结果状语从句可与t…t…或enugh…t…构成的简单句转换。
例句：The by is s yung that he can’t g t schl. =The by is t yung t g t schl. =The by is nt ld enugh t g t schl.
转换时t放在所修饰词之前。 t+adj./adv.enugh放在所修饰词之后。 adj./adv.+enugh
It was _______________(如此好的天气) that we decided t g fishing.All f us feel surprised that such a little by can eat _____________(如此多的食物).他以前从没见过如此宏伟的一处自然景观。4. 孩子们在夏令营里的生活是如此丰富，所以他们都想再次参加。
such gd weather
He has never seen such a wnderful natural wnder befre.
The children are having such clrful life in the camp that they all want t jin in the camp again.  
连接词：than, , nt , the+比较级…, the +比较级
注意：, nt 中间用形容词或副词的原级。
例句：1. The earth is bigger than the mn. 2. He writes as carefully as his sister. 3. The mre exercise yu take, the healthier yu will be. The harder yu wrk, the greater prgress yu will make.
1.连接词： thugh, althugh, even if, even thugh
例：Althugh/Thugh he is yung, he knws a lt. I’ll g even if/thugh it rains tmrrw.
【注】althugh和thugh可与yet或still连用，但不能与but连用。
连接词：where, wherever
Where there is water, there is life. 哪里有水，哪里就有生命。Wherever yu g, yu must bey the law.无论你到哪里，你都必须遵守法律。
地点状语从句 vs. 定语从句
where引导定语从句时，从句前应有一个表示地点的名词作先行词；状语从句前则无需先行词。
G back where yu came frm.(地点状语从句）你从何处来到何处去。
G back t the village where yu came frm.(定语从句，修饰village) 回到你来的那个村子里去。
连接词：as（正如，像……）, as if, as thugh（好像）
as if/thugh从句所表示的情况是事实或有很大可能用陈述语气，是主观想象或与事实相反时用虚拟语气。
例句：It lks as if it is ging t rain. (非虚拟语气) He talked as if he had seen the accident. (虚拟语气)
They dn’t knw if it _____________(rain) tmrrw. If it ________________(nt rain), they’ll g camping. 2.
