状语从句的高考考点
1:时间状语
When,while,as
Before, after,Until,since
when a man loves a woman,
he can‘t keep his mind on nothing else.
When you see him, please say hello to him.
I’ll call you when I get there.
When the film ended, people went back.
Please don’t talk so loud while others are working.
I met her while I was at school.
总结:
When既可引导持续的动作,也可以是短暂的动作,主句和从句的动作同时发生或从句的动作先与主句动作。
While引导的从句,必须是持续的动作,侧重主句动作和从句同时发生,相对比。
As she sang, tears rolled down her cheeks.
As years go by, China is getting stronger and richer.
总结:
As 用于主句从句动作同时发生,“一边…一边”
As “随着”
1.be doing …..when
2.be about to do ….when
3.be going to ……when
When的特殊用法
He was about to give up when he suddenly found the answer.
When 表示原因“既然”,“如果”
Why did you ask the teacher when you had already known the answer

How can we explain it to you when you won’t listen
They kept trying when they knew it was hopeless.
When:“尽管”
When in Rome, do as Romans do.
When (we are ) young, we are full of hope.
总结:
由 when 等引导的状语从句,如果主语与主句的主语一致或是 it ,谓语动词又含 be 动词时,主语和 be 动词常常被省略,就变成“ when + V-ing/ V-ed/ adj/ 介词词组”的结构。
He is tall while she is short.
Before, after, since
He usually drinks a cup of tea before he goes to school.
(He usually drinks a cup of tea before going to school. )
He usually drinks a cup of coffee after he comes back from school.
(He usually drinks a cup of coffee after coming back from school.)
Before they reached the station, the train had gone.
他们(还没)到火车站前,火车已开走了。
总结:
Before 从句中的谓语不用否定式。
It will be half a year before I come back.
It won’t be long before we meet again.
It is ten days since the earthquake broke out.
It is three years since I became a teacher.
总结:
It will be+段的时间+before从句
“多久以后才…”
It is +段的时间+since从句
“从…以来多长时间”
Great changes have taken places since you left here.
I have been here since two years ago.
Until, till, not…until

Wait till I call you.
The teacher had been ignorant of it until he was told the truth yesterday.
The teacher will not give the answers until we have finished the exercise.
I didn’t understand until you had explained it.
总结:
Until肯定句中,动词为延续性动词(walk,work,wait, live等)
Until否定句中,动词可以是瞬间的,心理状态(come,go,arrive,leave, know, understand, realize等)
Until否定句中,有before(在…以前的时候)意思。
Until you told me , I had heard nothing of what happened.
-Until when are you staying
-Until next Monday.
总结:
Until可放句首,till 不可以。
Until+ when 构成疑问句
地点状语从句
Where there is a will, there is a way.
Where there is smoke, there is fire.
Where there is life, there is hope.
Where there is water, there is life.
Wherever you go, whatever you do, I will be right here waiting for you.
区分
He lives where his uncle lives.
He lives in the room where his uncle lives.
总结区分:
1:地点状语从句是对谓语动词的补充说明
定语从句是对先行词的一种修饰(形容词对名词的修饰)
2:有无先行词
so that/in order that/in case/lest / for fear that
