英语中的分句，是指主从复合句，也就是指名词性从句、形容词性从句和副词性从句三大类型的从句。主从复合句各自的构成和用法，教材教辅中都有，本文不作赘述。本文仅就各类型分句在实际运用中常见的细小问题，做一次归纳，但愿本文能对今后将要参加高考的学子们有所帮助。
I. 分句运用中的若干细节
一、名詞性从句 （主语从句、宾语从句、表语从句和同位语从句）
1.
名词性从句通常为陈述句语序。
2. 名词性从句的引导词that， 无词意，也无语法功能，但有时却不能省略，如主语从句或宾语从句置于句首时;
当一个动词带有两个或两个以上的并列的宾语从句时， 第二个that不能省略。
3. 引导名词性从句表示疑问时，常用whether不用if
（宾语从句有时可例外）。 whether引导名词性从句时可以和or not 连用，而if则不能。
The question is whether
they can work out the difficult math problem.
Whether she comes or not
makes no difference.
4. what引导名词性从句，其意要视上下文而定。
What she said at
the meeting surprised us greatly.
She is not what she was 5 years
ago.
This is what they call Salt Lake City.
Our income now is
double what it was ten years ago.
I have no idea what we should do
next.
（一）主语从句
1.
what引导主语从句，在从句中作主语或宾语，而that引导主语从句时，不作句子成分，也没有任何含义，仅起连接作用但又不可省略，该句句意完整。
What really interested the children was how to use the computer.
What he
said surprised all of us.
That he is famous as an English teacher is
well known.
2. who可以引导主语从句，但往往具有疑问的意义;而whoever则没有疑问的意义，相当于anyone
who。
Who will give us a speech is unknown now.
Whoever leaves
the room last should lock the door.
3.
由于主语从句放在句首，句子常显得笨重，因此常使用it作形式主语，然后把主语从句移至句子后面。
It is known to us how he
became a writer.
It is a pity that you didnt come to Marys party last
night.
（二）宾语从句
1. 当主语是第一人称I / we
时，谓语动词think，believe，suppose，expect，guess等后面宾语从句中的否定词要转移到主句中，即主句的谓语动词用否定式，而从句的谓语动词用肯定式。
I dont believe he will come.
We dont think you are here.
注意：若谓语动词为hope，宾语从句中的否定词不能转移。如：I hope you werent ill.
2. 特殊疑问句由“特殊疑问词
do you think （believe / expect / suppose / say等） 陈述句语序”构成。
Mum is
coming. What present do you expect she has got for your birthday？
3.
如果在动词find， feel， think， make等后的宾语从句后有宾语补语时， 则可用it 作形式宾语，然后将用做宾语的从句后置。
We
must make it clear that anyone who breaks the law will be punished.
Some
students just take it for granted that theyll pass the exams.
4.
whatever 等引导宾语从句，也可引导状语从句，而no matter what只能引导状语从句。
I believe whatever he
says. （宾语从句）
Whatever （=No matter what） you say， I will not change my mind. （状语从句）
5. whoever引导宾语从句并在从句中作主语时，不能用whomever。
He wants to
become a friend of whoever shares the same interest.
6.
whether引導宾语从句，可作介词宾语，而if不可。
It all depends on whether they will support
us.
（三）表语从句
1. 表语从句用that引起，that仅起连接作用，无词义。表语从句也可用连接词how， when，
where， why， what引起，他们有词义又担任语法成分。
One thing I admire most about them is
that they are hospitable.
She works too hard;That is why she is
exhausted.
2. The reason why... is...句型中，应用that
引导表语从句，表示“……的原因是……”。不能用because引导。
The reason why I went was that I
wanted to meet my friends.
（四）同位语从句
1. 在某些名词 （如demand， wish，
suggestion， resolution等） 后面的同位语从句要用虚拟语气。
They were faced with the
demand that this tax be abolished.
The suggestion that the new rule be
adopted came from the chairman.
2.
当同位语从句意义不完整，需增加“是否”的含义时，应用whether引导同位语从句，if不能引导同位语从句。
Well discuss the
problem whether the sports meeting will be held on time.
3.
当同位语从句意义不完整，需增加“什么时候”“什么地点”“什么方式”等含义时，应用when， where， how等词引导同位语从句。
You
have no idea how worried I was！
4.
为了保持句子结构平衡，同位语从句有时可以与其同位的名词分开。
The news got about that he had won a car
in the lottery.
二、定语从句
定语从句由关系代词that， which， who， whom， whose， as 引导，且在定语从句中做主语或宾语，whom， which和that在从句中做宾语时，常可省略，但介词后的关系代词不能省略，as常与 such，the
same连用。
1. 关系代词在从句中作主语时，从句的谓语动词用单数还是用复数应由先行词决定。
The man who
lives downstairs speaks English fluently.
The students who are in Grade
Three are going to climb the hill tomorrow.
2. that与which， who，
whom的用法之区别：
1） 只用that的情况
① 先行词为all， everything， anything，
nothing， little， much等不定代词时。
He told me everything that he
knows.
② 先行词被all， any， every， each， much， few， little， no，
some等修饰时。
All the books that you offered has been given out.
③
先行词有形容词最高级或序数词修饰时。
This is the best film that I have ever read.
④ 有两个先行词，一个指人而另一个指物时。
We talked about the persons and things that we
remembered.
⑤ 先行词被the only， the very修饰时。
He is the only man that
I want to see.
⑥ 句中已有who或which时，为了避免重复时。
Who is the man that is
making a speech？
2） 只用which， who， whom的情况 ①
在非限制性定语从句中，只能用which指代物，用who / whom指人。
He has a son， who has gone abroad
for further study.
② 在由“介词 关系代词”引导的定语从句中，只能用which指物，whom指人。
I
like the person to whom the teacher is talking.
③ 先行词本身是that时，关系词用which，
先行词为those， one， he时（指人时）用who。
Those who respect others are usually
respected by others.
特别提醒：
先行词为situation， case，point， stage，activity，age等，意指某人或某事所处的“某种情景或状态”，或指某事所发展或达到的“某种地步或程度”;他们都是指“在这种情景、状态下”
或“在某个时间”，因此，需用where， when等关系副词来引导定语从句。
The accident had reached to a
point where both their parents are to be called in.
We have entered into
an age when dreams have the best chance of coming true.
三、状语从句
（一）让步状语从句
1. “疑问词 ever”或“no matter 疑问词”表示“不管……”的含义，引导让步状语从句。
However （= No matter how） much I tried， I failed to work out the maths
problem.
Whatever （=No matter what） you say， I will not change my
mind.
Whenever （=No matter when） you come， you will be warmly
welcomed.
Wherever （=No matter where） you go， you will find the same
thing.
Whoever （=No matter who） you are， you have no right to do such a
thing.
2. “whether... or...” 可以引导含选择范围的让步状语从句，意为“不管……”。
I shall
go， whether you come with me or stay at home.
Whether she wins or loses，
this is her last chance.
（二）时间状语从句
表示“一……就……”的句式：
1. hardly / scarcely / rarely... when / before， no sooner... than和as soon
as都可以表示“一……就……”的意思。
I had hardly / scarcely got home when it began to
rain.
I had no sooner got home than it began to rain.
As soon as
I got home， it began to rain.
注意：如果hardly， scarcely 或no
sooner置于句首，句子必须用倒装结构。
Hardly / Scarcely had I got home when it began to
rain.
No sooner had I got home than it began to rain.
2. immediately， directly， instantly， the moment， the instant， the
minute等引导的时间状语从句，表示“一……就……”。
I will go there directly I have finished my
breakfast.
The moment I heard the news， I hastened to the spot.
3. while 的多用途
① 引導时间状语从句，从句中的谓语动词应用延续性动词或表示状态的词。
While the
discussion was still going on， George came in.
Strike while the iron is
hot.
② 引导让步状语从句，多用于句首，意为“尽管，虽然”。
While I admit his good points I can see his bad ones.
③ while作并列连词用，意思为“而，然而”，表前后意义上的对比或转折。
Theres plenty of rain in the southeast， while theres little in the
northeast.
（三）方式状语从句通常由as， （just） as... so...， as if， as
though引导。
1. as， （just） as...so...引导的方式状语从句通常位于主句后，但在 （just）
as...so...结构中位于句首，这时as从句带有比喻的含义，意思是“正如……”，“就像”，多用于正式文体。
Always do to the
others as you would be done by.
As water is to fish， so air is to
man.
Just as we sweep our rooms， so we should sweep backward ideas from
our minds.
2. as if， as though
两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。意为“仿佛……似的”“好像……似的”。
He looks as if （as though） he had been hit by lighting.（与事实相反，谓语用虚拟语气。）
（四） 结果状语从句常由so... that 或 such... that引导
so是副词，只能修饰形容词或副词。 so 还可与表示数量的形容词many， few， much， little连用，形成固定搭配。such 是形容词，修饰名词或名词词组， so...
that与such... that之间的转换即是so与such之间的转换。
The boy is so young that he cant
go to school.
He is such a young boy that he cant go to school.
II. 分句与分词（非谓语动词）间的转换
一、与动词不定式间的转换
1） 名词性从句与动词不定式之间的转换

→ They set out
early in order to（so as to）arrive in time.
She was so excited that she
couldnt go to sleep. （结果）
→ She was so excited as not to sleep.

that引导的主语从句可转换成Ving作主语

learning French.

too much on him.

④
当状语从句的主语和主句的主语一致时，从句可以将主语和be动词简化掉。
常用：连词 形容词 / ving / ved / to do
/名词/介词短语
Work hard when （you are） young， or youll regret.
Although （he was） a farmer， now he is a famous director.
Although （he
is） doing his best in maths these days， he has still got no good marks.
He wont go there with us unless （he is） invited.
He stood up as if （he
were） to say something.

trouble.
注意：当状语从句主语和主句主语不一致时， 从句部分常用独立主格结构来表达。

was over， we continued our journey.

continued our journey.
If all things are considered， her paper is better
than yours.
