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<
br>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.
易混引导词while, when, as的区别:
既可以指时间点与瞬间动词连用,也可以指时间段,与延续性动词连用
(=while)。如:
When he came in, his mother was cooking.
When (While) we were at school, we went to
the library every day.
While表示时间段,因此,while
从句的谓语动词要用延续性动词。如:
Please don't talk so loud
while others are working.
As与when用法相似,但着重强调主
句动作与从句动作同时发生,有随着……或
一边……一边……之意。如:
As you
get older, you get more
knowledge.随着年龄的增长,你获得的知识就越多。
2.Because,as,since 的区别:
Because用于表示直接原因,回答why提出的问题,语气最强;As用于说明原因,
着重
点在主句,常译成由于;since表示显然的或已知的理由或事实,常译成既然。如:
Water is very important because we
can't live without it.
He didn't come
yesterday as his mother was ill.
I'll do it
for you since you are busy.
3.such…that,
so…that, so that 引导结果状语从句的区别:
such是形容词,修饰名词;
so 是副词,修饰形容词或副词。其结构如下:
1) such + a (n)+
形容词+单数可数名词+that……
2) such+形容词+复数可数名词+that ……
3) such +形容词+不可数名词+that……。如:
This was
such a good film that I went to see it several
times.
It was such good books that they sell
well.
It was such bad weather that I had to
stay at home.
He spoke so fast that I
couldn't follow him.
He is such a lovely boy
that we all like him.
=He is so lovely a boy
that we all like him.
注:在形容词+可数名词复数不可数名词结构中,当名词前有many, much, few,
little
表示数量的多少时,名词前用so。如:
She made so
many mistakes that she didn't pass the exam.
