状语从句
一、定义
充当状语
在整个句子结构中的句子,引导状语从句的连接词就是。同时,根据连词的不同,可以判断出不同类别的状语从句。
状语从句可以修饰谓语、非谓语、定语、其他状语或整个句子。(与副词的作用类似,可以对比记忆、理解。比如,副词一般在句子中作状语,可以修饰动词、形容词、其他副词或整个句子。)
例如:
if
Wewill go for a picnicit doesn’t rain tomorrow.如果明天不下雨,我们就去野炊。
(连词if引导的是条件状语从句,在整个句子中充当状语,修饰整个句子。)
二、初中常见状语从句
(中考常见的引导状语从句的连词,用蓝色字体加粗,一定要掌握)
【注意】
时间/条件状语
从句中,要用一般现在时代替一般将来时,如“主将从现”原则、主情从现、主祈从现原则。(现在完成时表示将来完成时。※不要求必须掌握)
1.时间状语从句
W
,once, by the time,the minute/ the moment(一...就...), every/each time, whenever,...
(1)When & while &as
①When:
表示“当...时”,后面跟时间点、时间段均可,因而从句的动词可以是非延续性动词(又叫短暂性动词)或延续性动词。
例如:
He was watching TV when his mom came back.当他妈妈回来时,他正在看电视。
When his mom was cooking, he was watching TV.当他妈妈做饭的时候,他正在看电视。
②While:
表示“当..时”,后面只能跟时间段,因而从句的动词也只能是延续性动词,且常为进行时态(现在进行时或过去进行时)。
例如:
While his mom was cooking, he was watching TV.当他妈妈做饭的时候,他正在看电视。
③as:
表示“一边...一边...”
【注意】与while区分:当一个人同时进行两个动作时(即主从句的主语是同一个人时),只能用as。
还可表示“随着...”。
例如:
Tom sings as he works. Tom一边唱歌一边工作。
As time went by, I learned how to be strong.随着时间的流逝,我学会了如何变得坚强。
(2)until & till(介词/连词)
until:
表示“直到...”, 表示某个动作或状态一直持续到...为止。
例如:
They waited until/till their mom came back.他们一直等到妈妈回来。
(主句谓语动词为延续性动词)
“not...until”表示“直到...才”。
He won’t go to bed until his father comes back.直到他的父亲回来,他才上床睡觉。
(主句谓语动词为非延续性动词)
(3) since:
表示“自从...”。它引导的从句用一般现在时,主句用现在完成时。
Eric has worked here since he came to Chongqing.自从Eric来到重庆,就一直在这里工作了。
(4)as soon as:
表示“一...就...”(考察“主将从现”较多)
例如:
Lucy will turn on the TV as soon as she gets home. Lucy一到家就会打开电视。
(5)before & after表示“在...之前/之后”
例如:
Before I could say anything, he rushed out of the room.我还没来得及说话,他就从屋子里冲了出去。
(6)其他:
例如:The minute I sat down in front of the TV, my mom came over.我一坐在电视机前,妈妈就过来了。
2. 条件状语从句
If如果, unless除非, as long as只要
,in case that(如果), on condition that(如果)等。
例如:
We’ll go for a picnic if it doesn’t rain tomorrow.如果明天不下雨,我们就去野炊。
=We’ll go for a picnic unless it rains.
【注意】if...not...=unless
3. 原因状语从句
because因为, as由于, since既然,
for因为
例如:
-----Why don’t you like English?你为什么不喜欢英语?
-----Because it’s very hard.因为它很难。
Since everyone is here, let’s begin.既然每个人都到了,咱们开始吧。
As she was not well, I went there alone.她身体不好,所以我单独去了。
He had a great desire to have a home of his own for he had always lived with my grandmother.他强烈渴望拥有一个属于自己的家,因为他一直和我祖母住在一起。
4. 结果状语从句
so...that..(如此..以至于), such...that..., (如此...以至于),
so that结果/以至于
例如:
so
The girl isyoungshe can’t go to school.这个女孩太小了,以至于她还不能去上学。
=The girl isn’t old enough to go to school.
=The girl is too young to go to school.
(so...that...常与not...enough to do和too...to...结构互换)
such
She wasa young girlshe can’t go to school.她是如此小的一个女孩,以至于她还不能去上学。
so that
I got up early,I caught the early bus.我早早就起床了,结果赶上了早班车。
【注意】such与so的区别
口诀:
名前such,形、副so,
多多少少也用so,
little属特殊,“小”用such,“少”用so。
5. 目的状语从句
so that(以便/为了),in order that(为了),
常与情态动词(may, might, can, could, will, would等)连用。
例如:
I’ll run slowly so that you can catch up with me.我会慢慢走,以便你能赶上我。
=I’ll run slowly in order that you can catch up with me.
【注意】
当主、从句的主语一致时,状语从句可用“in order to +do; so as to+ do; to+do”替换,从而将复合句转换成简单句。
例如:
He gets up early so that he can catch the early bus.为了赶上早班车,他很早就起床了。
=He gets up early in order that he can catch the early bus.
=He gets up earlyin order tocatch the early bus.
=He gets up earlyso as tocatch the early bus.
He gets up earlytocatch the early bus.
6. 让步状语从句
t
even if/though即使,
whether...or...(不管是...还是.../不困是否),
no matter what/when/how或“疑问词+ever”(无论...)等。
例如:
Although/Though the plot is weak, (yet) the action is very fantastic.虽然剧情平淡,但是影片动作设计非常精彩。
(although/though不能与but连用,但yet可以。)
Even if you’re successful in your studies, you must still work hard.即使你学业上很成功,你也仍必须努力学习。
Whether
you believe itnot, it is true.不管你信不信,这是真的。
Whatever
the parents do, they wish all the best for their kids.不管父母做什么,他们都希望自己的孩子一切都好。
小拓展:(不要求必须掌握)
部分倒装
as引导的让步状语从句必须以的形式出现,被倒装的部分可以是表语、状语或动词原形,though也可用于这样的结构中(口语)。
例如:
Child as he was, he knew many things that I didn’t know.尽管他还是个孩子 ,但他知道很多我不知道的事。
=Although he was a child, he knew many things that I didn’t know.
7. 比较状语从句
as..as...(和...一样...),not as/so... as...(不如...),that(...比..),the more...the more...(越...就越...)
等。
例如:
than
My sister is tallerme.我的妹妹比我高。
The more
you eat,you’ll be.你吃得越多,长得越胖。
8. 地点状语从句
where, wherever
, anywhere, everywhere
例如:

9. 方式状语从句
