1、时间状语从句
连词：when, before, after, as soon as, as, while, hardly had…when, scarcely had …when, no sooner had … than, till / until, since, the moment, by the time 等，
I loved history when I was at school.
Why do you want a new job when you’ve got such a good one already？
Strike while the iron is hot．
The students took notes as they listened．
when可以和延续性动词连用，也
可以和短暂性动词连用；而while
和as只能和延续性动词连用
固定句型：sb. was/were doing sth when sth. did.
某人正在做某事的时候，某事正在发生。
The students (play) football outdoors when the educator arrived.
sb. be about to do when sth did
sb. be on the point of doing when sth did
sb. had just done sth. when sth did
were playing
before相关句子：

before相关句子：

before相关句子：

until与till的用法与区别：
①until/ till 修饰的谓语动词为延续性动词。在句首时多用until.
Let’s wait till / until the rain stops
Until then, I knew nothing at all about it.
②主句谓语动词为非延续性动词时，应用 not….until….句型
She didn’t come back until this morning.
I fell asleep the moment I closed my eyes.
Everytime I hear that song, I feel happy.
the moment/minute/instant, the day, the year, each time/every time, next time, the first time, by the time起连词作用，引导时间状语从句
△ 如果把no sooner, hardly, scarcely, barely置于句首，它所连带的这部分就要倒装，如：
No sooner had she heard the news than she fainted.
(She had no sooner heard the news than she fainted.)
since的用法：
since表从过去某一时间或动作、事情起
到目前为止，“自….以 来”
①、引导状语从句时，主句用现在完成时（或现在完成进行时）时，从句中用一般过去时。
I’ve been living here since I came to Beijing.
.
②、常用句型： it is (has been)…..+ since +一般过去时
It is five years since I began to learn English.
as
①多用于动作发生时间较短时，常有“正当….之时”之意
She fell of the bus as she got down.
② 表“边…边…”或“随着….”之意时常用as
He whistled as he rode on.
As time went on, he became less active.
③ as表 “由于….” 引导原因状语从句
I’m not going out as I have a lot to do.
④ as用于表“虽然”的倒装句中。
Young as she is, she is already a professor.
Child as he is, he knows a lot.
2、地点状语从句
连词：where, wherever (no matter where)
注意：都和where相关

Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。
Bamboo grows well where it is warm and wet.
You may go wherever you like.
Everywhere they went, they were kindly received / warmly welcomed.
We’ll go anywhere the Party directs us.
3、原因状语从句
(1) 连词： because, since, as , now that
(2) because, since, as, for 用法比较：
一）. because: 语气最强，回答why时用because，所表示的是直接理由，因果关系不能同so连用。
Why are you late Because there is a traffic jam.
二）. since: “既然…..” 表对方已知的事实或理由，常放在句首。
Since you have got enough money with you now, you can come and buy it next time.
三）. as: “由于….” 语气较弱，较口语化，表明显的原因或已知的事实，常放在句首。
As he had been ready for the worst, he was not disappointed at the result.
四）. for是一个等立连词，连接的是两个并列的分句，其他三个引导的是状语从句；for不能放在句首。
It must have rained last night, for the ground is wet.
4、条件状语从句
连词：if, unless, (if not) , on condition that , as long as。
注意：有时可以把祈使句作为条件状语从句 Give him an inch and he’ll take a mile.
(= If you give him an inch, he’ll take a mile. )
但：
当表示否定的条件时，可用连词or 或otherwise
Start at once, or / otherwise you’ll miss the train.
(= If you don’t start at once, you’ll miss the train.)
5、目的状语从句
连词：so that, in order that, lest, for fear that, in case
She made a detailed plan so that everything could go smoothly.
He emphasized this point again and again, for fear that she should forget it.
当目的状从主语和主句主语相同时候，
可以用不定式短语或介词短语替换状从
He set out early so that he could attend the class on time.
=He set out early so as to attend the class on time.
He left two hours early for fear that he should miss the train.
=He left two hours early for fear of missing he train.
6、结果状语从句
连词：so that, so...that..., such...that...
She finished her work so that she left the office on time.
It was such terrible weather that we couldn’t go for a walk.
so that引导让步状从和结果状从区别：
目的状从：为了，以便
句子有can, could, may, might, would, should
结果状从：因此，所以
句子没有情态动词
She took a short cut so that she could catch up with her friends.
她抄了近道，以便能追上她的朋友们。
She took a short cut, so that she caught up with her friends.
她抄了近道，因此追上了她的朋友们。
7、让步状语从句
连词：though/although, even if/ even though, no matter who/ what/ when / where/ which / how ( whoever, whatever, whenever, wherever, whichever, however)
疑问词+ever=no matter+疑问词，“无论......”
No matter what he did, nobody liked him.
=Whatever he did, nobody liked him.
在名词性从句中，不能用no matter+疑问词
I will eat whatever you give me.
while（尽管）
while放句首表转折
While he is a little boy, he can help his mom a lot.
while放句中表对比
There is plenty of rain in the southeast, while there is little in the northwest.
Although/Though he was tired, he still went on with his work.
①although和but不能连用
②although放句首不倒装，as/though需要倒装
倒装原则：将从句最后一个词或短语放在句首，although改为as、though
Tired though/as he was, he still went on his work.
8、方式状语从句
as, as if, as though 来引导
You must do the exercises as I show you.

the way (that) , how, like等来引导

主要用在形容词、副词的原级、比较级、最高级。
原级： as …as … not so / as …as
比较级: 比较级+ than …
最高级： 最高级+in / of / among …
