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。
1. 时间状语从句
(1)时间状语从句常用when, as, while,
before, after, since, till, until,
as soon
as等连词来引导。例如:
It was raining hard when got to
school yesterday.
While he was doing his
homework, the telephone rang.
As he walked
along the lake, he sang happily.
He had
learned a little Chinese before he came to China.
After he finished middle school, he went to
work in a factory.
(2)在时间状语从句里,通常不用将来时态,用现在时态表示将来的动作或
状态。例如:
I’ll ring you up as soon as I get to New York.
I will tell him everything when he comes back.
He won’t believe it until he sees it with his
own eyes.
(3)在带有till或until引导的时间状语从句的主从复合句里,如果主
句用
肯定式,其含义是“一直到……时”,谓语动词只能用延续性动词。如果主
句用否定式,其
含义是“直到……才……”, “在……以前不……”, 谓语
动词可用瞬间动词。例如:
The young man read till the light went out.
Let’s wait until the rain stops.
We won’t
start until Bob comes.
Don’t get off until the
bus stops.
2. 条件状语从句
(1)条件状语从句通常由if,
unless引导。例如:
What shall we do if it snows
tomorrow?
Don’t leave the building unless I
tell you to.
(2)在条件状语从句里,谓语动词通常用现在时态表示将来的动作或状态。
例如:
I’ll help you with your English if am free
tomorrow.
He won’t be late unless he is ill.
(3)“祈使句 + and (or)+ 陈述句”
在意思上相当于一个带有条件状语从
句的复合句。例如:
Hurry up, or
you’ll be late.
=If you don’t hurry up, you’ll
be late.
Study hard and you will pass the
exam.
=If you study hard, you will pass the
exam.
3. 原因状语从句
(1)原因状语从句通常由because,
since, as引导。例如:
He didn’t come to school
because he was ill.
As it is raining, we shall
not go the zoo.
Since you can’t answer the
question, I’ll ask someone else.
(2)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。As和since语气较弱,
一般用来表示明显的原因。由as和since引导
的原因状语从居多放在句首。
例如:
------Why aren’t going
there?
------Because I don’t want to.
As
he has no car, he can’t get there easily.
Since we have no money, we can’t buy it.
(3)because和so不能同用在一个句子里。
4. 结果状语从句
(1)结果状语从句由so…that, such…that, so that引导。例如:
He is so poor that he can’t buy a bike for his
son.
She is such a good teacher that everybody
likes her.
My pencil fell under the desk, so
that I couldn’t see it.
(2)so…that语such...that可以互换。例如:
在由so...that引导的结果状语从句中,so是副词,与形容词连用。其结构
是:
“...so + 形容词(副词)+ that + 从句”。例如:
He was so
glad that he couldn’t say a word.
The hall is
so big that it can hold 2,000 people.
Mother
lives so far away that we hardly ever see her.
在由such…that引导的结果状语从句中,such是形容词,它修饰的可以是
单数或复数可数
名词,也可以是不可数名词;名词前面可以带形容词,也可
不带。如果是单数可数名词,前面需加不定冠
词a或an。例如:
It was such a hot day that nobody
wanted to do anything.
He had such long arms
that he could almost touch the ceiling.
He
made such rapid progress that he did very well in
the mid-term.
有时上述两种结构是可以互换的。例如:
It
was such a wonderful film that all of us wanted to
see it again.
=The film was so wonderful that
all of us wanted to see it again.
It is such
an important match that nobody wants to miss it.
=The match is so important that nobody wants
to miss it.
(3)如果名词前由many, much, little,
few等词修饰时,只能用so, 不用
such。例如:
Soon
there were so many deer that they ate up all the
wild roses.
He has so little time that he
can’t go to the cinema with you.
5. 比较状语从句
比较状语从句通常由as…as, 比较级 + than…等连词引导。例如:
Tom
runs faster than John does.
This classroom is
as big as that one.
6. 目的状语从句
(1)目的状语从句通常由
so that, in order that引导。例如:
We started early
so that we could catch the first train.
He
studies hard so that he could work better in the
future.
We used the computer in order that we
might save time.
(2)so that既可引导目的状语从句,又可引导结果状语
从句。区别这两种从
句的办法有两个:1)目的状语从句里往往带有情态动词can, could,
may,
might等。2)从意思上看,目的状语从句往往表示的目的很明确。例如:
Speak clearly so that they may understand you.
(目的状语从句)
Jack is badly ill so that he has to
rest. (结果状语从句)
7. 让步状语从句
(1)让步状语从句通常由although, though等连词引导。例如:
Though he is young, he knows a lot.
Although I am tired, I must go on working.
(2)although(though)不能用在同一个句子中。例如:
我们不能说:Though it was raining hard, but he still
went out.
应该说:Though it was raining hard, he
still went out.或It was raining
hard, but he
still went out.
8. 地点状语从句
地点状语从句常常由where来引导。例如:
Go where you like.
Where there is a will, there is a way.

more exercise, such as running
and walking.

on working?

have a rest.

though

A. when
B. until C. after D. though
答案:B。该题考查的是引导状
语从句的从属连词选择。本句的意思是“在……

意思应用“not…until” 这一句型。
4.---I hope you’ll
enjoy your trip, dear!
---Thank you, mum.
I’ll give you a call _________ I get there.
A. until B. as soon as C. since D. till
答
案:B。该题考查的是引导状语从句的从属连词的选择。本题的意思是“一
到那里,我就给你打电话。”
