高中英语从句大全
句子成分：英语句子成分分为七种：主语、谓语、宾语、定语、状语、表语、宾语补足语。
定义：主从复合句中的从句在整个句子中担任什么成分，就叫做什么成分从句。
构成：关联词+简单句（定语从句还有先行词）
状语从句还分很多种，比如条件状语if从句，原因状语because 从句，目的状语so that 从句等；
定语从句分限定性定语从句和分限定性定语从句
1、主语是句子所要说的人或事物,回答是“谁”或者“什么”。通常用名词或代词担任。如：I’m Miss Green.(我是格林小姐)
2、谓语动词说明主语的动作或状态,回答“做(什么)”。主要由动词担任。如：Jack cleans the room every day. (杰克每天打扫房间)
3、表语在系动词之后,说明主语的身份或特征,回答是“什么”或者“怎么样”。通常由名词、代词或形容词担任。如：My name is Ping ping .(我的名字叫萍萍)
4、宾语表示及物动词的对象或结果,回答做的是“什么”。通常由名词或代词担任。如：He can spell the word.(他能拼这个词)
有些及物动词带有两个宾语,一个指物,一个指人。指物的叫直接宾语,指人的叫间接宾语。间接宾语一般放在直接宾语的前面。如：He wrote me a letter . (他给我写了一封信)
有时可把介词to或for加在间接宾语前构成短语,放在直接宾语后面,来强调间接宾语。如：He wrote a letter to me . (他给我写了一封信)
5、定语修饰名词或代词,通常由形容词、代词、数词等担任。如：
Shanghai is a big city .(上海是个大城市)
6、状语用来修饰动词、形容词、副词,通常由副词担任。如：He works hard .(他工作努力)
7、宾语补足语用来说明宾语怎么样或干什么,通常由形容词或动词充当。如：They usually keep their classroom clean.(他们通常让教室保持清洁) / He often helps me do my lessons.(他常常帮我做功课) / The teacher wanted me to learn French all by myself.(老师要我自学法语)
☆同位语通常紧跟在名词、代词后面,进一步说明它的情况。如：Where is your classmate Tom ?(你的同学汤姆在哪里？)
1）表语从句
.引导表语从句的关联词的种类：
（1）从属连词that.如：
The trouble is that I have lost his address.麻烦是我把他的地址丢了。
（2）从属连词whether，as，as if.如：
He looked just as he had looked ten years before.他看起来还与十年前一样。
The question is whether they will be able to help us.问题是他们是否能帮我们。
注：从属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：
All this was over twenty years ago，but it’s as if it was only yesterday.
这都是20多年前的事了，但宛如昨天一样。
能跟表语从句的谓语动词一般为系动词be，seem，look等。如：

2.在一些表示“建议、劝说、命令”的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如：
My suggestion is that we （should）start early tomorrow.我的建议是我们明天一早就出发。2）主语从句
引导主语从句的关联词有三类：
（1）从属连词that.如：That they were in truth sisters was clear from the facial resemblance between them.

E.It+doesn’t matter（makes no difference，etc.）+连接代词或连接副词引起的主语从句。如：
It doesn’t matter whether she will come or not.她是否来这无关紧要。
It makes no difference where we shall have the meeting.我们在哪里开会毫无区别。
F.当that引导的主语从句出现在疑问句中时，要以it作形式主语，而把主语从句后置。如：
Is it true that the scientist will give us a lecture next week？下周那位科学家将给我们作报告是真的吗？
Does it matter much that they will not come tomorrow？他们明天不来很要紧吗？
G.当主语从句出现在感叹句中时，要以it作形式主语，而把主语从句后置。如：
How strange it is that the children are so quiet！孩子们这么安静真奇怪！
2.注意连接代词whoever，whatever，whichever等引导主语从句的含义。
Whoever comes will be welcome.（whoever=the person who）来的人将受到欢迎。
Whatever he did was right.（whatever=the thing that）他所做的事情是正确的。
Whichever of you comes in will receive a prize.（whichever=anyone of you who）你们当中不论哪个进来将会得到奖
3）宾语从句
引导宾语从句的关联词有三类：
（1）从属连词that.如：
He told us that he felt ill.他对我们说他感到不舒服。
I know he has returned.我知道他已经回来了。
注：that在引导宾语从句时也并不是任何情况下都可以省略。在以下情况下，that不能省略。
1.Everybody could see what happened and that Tom was frightened.（and连接两个宾语从句，that宾语从句放在and的后面时，that不能省略。）
大家都会看出所发生的事情并知道Tom非常害怕。
2.I know nothing about him except that he is from the south.（that引导的宾语从句作介词宾语时，that不能省略。）
对他我一无所知，只知道他是南方人。
3.That he ever said such a thing I simply don’t believe.（that从句位于句首时，that不可省略。）
我简直不相信他曾说过这样的话。
4.We decided，in view of his special circumstances，that we would admit him for a probationary period.（主句谓语动词与that从句之间有插入语，that不可省略。）鉴于他的特殊情况，我们决定应允他一段试用期。
（2）从属连词if/whether.如：
I doubt whether he will succeed.我怀疑他是否会成功。
I don’t know if you can help me.我不知道你能否帮助我。
（3）连接代词who，whom，whose，what，which，whoever，whatever，whichever 连接副词where，when，how，why.

I wonder what he’s writing to me about.我不知道他要给我写信说什么事。
I’ll tell you why I asked you to come.我会告诉你我为什么要你来。
You may do what you will.你可做任何你想做的事。
介词宾语从句
宾语从句也可用作介词的宾语。如：
He was deeply displeased by what had occurred that day.
他对那天发生的事感到很不快。
I walked over to where she sat.我走向她坐的地方。
I am curious as to what he will say.我很想知道他要说什么。
Your success will largely depend upon what you do and how you do it.
你是否成功将主要取决于你做什么和怎样做。
有时介词可以省略。如：
I don’t care （for）who marries him.我不管谁跟他结婚。
Be careful （as to）how you do that.你要注意做这件事的方式。
解释：
1.如果宾语从句后还有宾语补足语，则用it作形式宾语，而将宾语从句后置。如：
We thought it strange that Xiao Wang did not come yesterday.
我们认为小王昨天没来是奇怪的。
He has made it clear that he will not give in.
他已表明他不会屈服。
2.作介词的宾语：连词that引导的名词性从句很少作介词的宾语，只用在except，but，in后。其他一些介词的宾语从句如果由连词that引导，则需用it先行一步，作形式宾语。如：
He is a good student except that he is careless.
他是一个好学生，只是有点粗心。
You may rely on it that I shall help you.你可以指望我会帮助你的。
介词宾语不可以用which来引导，而要用what来引导。如：
Are you sorry for what you’ve done？
你为你所做的一切感到内疚吗？
3.某些形容词或过去分词后常接宾语从句，这类形容词或过去分词有sure，glad，certain，pleased，happy，afraid，surprised，satisfied等，连词that可省略。如：
I am not sure what I ought to do.
我不能确定我该做什么。
I’m afraid you don’t understand what I said.
恐怕你没领会我说的意思。
I’m surprised that I didn’t see all that before.
我好奇怪，我以前没看到过。
Mother was very pleased her daughter had passed the exams.
妈妈为她的女儿通过了考试而感到高兴。
4.连词whether （…or not）或if引导的宾语从句
if和whether引导的宾语从句可以互换使用，但whether常和or not连用，if一般不与or not连用。如：
I wonder whether it is true or not.我不知它是真是假。
用if引导宾语从句如果会引起歧义，应避免使用if而用wheter.试比较：
Please let me know if you want to go.
Please let me know whether you want to go.
if从句可理解为宾语从句，意为“请告诉我你是否想去”；此句又可理解为条件状语从句意为“如果你想去的话，请告诉我一声”。
5.宾语从句的否定转移。在think，believe，suppose，expect等动词后的宾语从句，有时谓语尽管是否定意思，却不用否定形式，而将think等动词变为否定形式。如：
I don’t think you are right.我认为你错了。
I don’t believe they have finished their work yet.我相信他们还未完成他们的工作。
I don’t suppose he cares，does he？我想他不在意，是吗？
6.宾语从句的时态变化规律：
（1）当主句是一般现在时态时，从句可根据需要用任何时态。
（2）当主句是一般过去时态时，从句只能使用过去范围内的任何时态。但客观真理除外。如：
The teacher said that the earth goes round the sun.
老师说地球绕着太阳运行。
4）同位语从句
1.定义：用作同位语的从句叫做同位语从句。
2.用法：同位语从句的先行词多为fact，news，idea，thought，question，reply，report，remark等，关联词多用从属连词that.如：
They were all very much worried over the fact that you were sick.
对你生病这件事，他们都很焦虑。
Where did you get the idea that I could not come？
你在哪儿听说我不能来？
Early in the day came the news that Germany had declared war on Russia.
德国已对俄国宣战的消息一大早就传来了。
注：同位语从句偶尔由从属连词whether引导。如：
I have no idea whether he’ll come or not.我不知道他是否来。
连接代词who，which，what和连接副词where，when，why，how亦可引导同位语从句。
The question who should do the work requires consideration.
谁该干这项工作，这个问题需要考虑。
We haven’t yet settled the question where we are going to spend our summer vacation.
到哪儿去度暑假，这个问题我们还没有决定。
It is a question how he did it.
那是一个他如何做了此事的问题。
解释：
1.that引导的同位语从句与定语从句之区别
that引导的同位语从句
that引导的定语从句
句法功能上
that只起连接从句的作用，无意义。在从句中不充当句子成分。不可省。
that替代先行词在从句中不仅起连接作用，还充当一个句子成分。如在从句中作动词的宾语时可省略。
意义上
从句是被修饰名词的内容。
从句起限定作用，是定语
如：The news that Mr.Li will be our new English teacher is true.（同位语从句，that不可省。）李先生将是我们的新英语老师这个消息是真的。
The news （that）he told me yesterday is true.（定语从句，that在从句中作told的宾语，可省。）
他昨天告诉我的消息是真的。
2.一些表示“建议、命令、要求”的名词后所跟的同位语从句中，谓语动词用虚拟语气should+动词原形表示。should可省。如：
This is our only request that this （should）be settled as soon as possible.
这就是我们唯一的请求：尽快解决这个问题。
5）状语从句
由从句担任的状语，在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子，它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等。状语从句是一较大的语法项目，也是近几年高考题中常见的一个重要试点。高考中已考查了时间、让步、地点、条件、目的等状语从句，这些从句仍是今后高考热点，应作充分准备。同时对方式状语从句也应引起重视。
（一）时间状语从句
表示时间的状语从句可由when, as, while, whenever, after, before, till (until), since, once, as soon as (或the moment ), by the time, no sooner … than, hardly (scarcely) … when, every time等引导。
e.g. When I came into the office, the teachers were having a meeting.
He started as soon as he received the news.
Once you see him, you will never forget him.
No sooner had I gone to bed than I went to sleep.
（二）原因状语从句
原因状语从句是表示原因或理由的，引导这类从句的最常用的连词是because, since, as , now that（既然）等，for 表示因果关系时（它引导的不是从句）为并列连词，语气不如because 强。
e.g. He is disappointed because he didn't get the position.
As it is raining, I will not go out.
Now that you mention it, I do remember.
（三）地点状语从句
引导地点状语从句的连词是where 和wherever等。
e.g. Sit wherever you like.
Make a mark where you have a question.
（四）目的状语从句
引导目的状语从句最常用的词（组）是so, so that（从句谓语常有情态动词）, in order that, in case（以防，以免）等。
e.g. Speak clearly, so that they may understand you.
She has bought the book in order that she could follow the TV lessons.
He left early in case he should miss the train.
（五）结果状语从句
结果状语从句是表示事态结果的从句，通常主句是原因，从句是结果。由so that （从句谓语一般没有情态动词）, s o … that, such … that等引导。
e.g. She was ill, so that she didn’t attend the meeting.
He was so excited that he could not say a word.
She is such a good teacher that everyone admires her.
（六）条件状语从句
条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句。引导条件状语从句的词（组）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：条件从句中的if 不能用whether 替换。
e.g. If he is not in the office, he must be out for lunch.
You may borrow the book so long as you keep it clean.
So far as I know（据我所知）, he will be away for three months.
You can go swimming on condition that ( = if ) you don’t go too far away from the river bank.
If he had come a few minutes earlier, he could have seen her.
（七）让步状语从句
让步状语从句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引导。注意：as引导的让步状语从句一般是倒装的。
e.g. Though he is a child, he knows a lot.
Child as he is, he knows a lot.
Whatever ( = No matter what ) you say, I’ll never change my mind.
（八）方式状语从句
方式状语从句常由as, as if (though), the way, rather than等引导。
e.g. You must do the exercise as I show you.
He acted as if nothing had happened.
（九）比较状语从句
比较状语从句常用than, so (as) … as, the more … the more等引导。
e.g. I have made a lot more mistakes than you have.
He smokes cigarettes as expensive as he can afford.
The busier he is, the happier he feels.
使用状语从句时要注意的几个问题
1、在时间和条件（有时也在方式、让步等）从句中，主句是一般将来时，从句通常用一般现在时表示将来。
e.g. We’ll go outing if it doesn’t rain tomorrow.
I’ll write to you as soon as I get to Shan ghai.
2、有些时间、地点、条件、方式或让步从句，如果从句的主语与主句主语一致（或虽不一致，是it），从句的谓语又包含动词be ，就可省略从句中的“主语+ be”部分。
e.g. When (he was) still a boy of ten, he had to work day and night.
If (you are) asked you may come in.
If (it is) necessary I’ll explain to you again.
3、注意区分不同从句：引导的是什么从句，不仅要根据连词，还要根据句子结构和句意来判别。以where为例，能引导多种从句。
e.g. You are to find it where you left it.（地点状语从句）
Tell me the address where he lives.（定语从句，句中有先行词）
I don’t know where he came from.（宾语从句）
Where he has gone is not known yet.（主语从句）
This place is where they once hid.（表语从句）
6）定语从句
定语从句及相关术语
1.定语从句：定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
2. 先行词:是定语从句的关系词前面的被定语从句所修饰的名词、代词.在定语从句中充
当一定的成分.
2.关系词：引导定语从句的关联词称为关系词，关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有where, when, why等。关系词常有3个作用：1，引导定语从句。2，在定语从句中担当一个成分。3，代替先行词。
Note：
关系词的选择依据在从句中所做的成分，先行词在从句中做主、定、宾语时，选择关系代词(who, whom, that, which, whose)；先行词在从句中做状语时，应选择关系副词( where 地点状语，when 时间状语，why 原因状语)
先行词和关系词二合一
A)Whoever spits in public will be punished here.(Whoever 可以用anyone who 代替)
B)The parents will use what they have to send their son to technical school. (what 可以用all that代替)
限定性定语从句
一、关系代词（在句中作主语、宾语或定语）
1. that既可代表事物也可代表人，which代表事物；它们在从句中作主语或宾语，that 在从句中作宾语时常可省略关系词，which在从句中作宾语也可以省略。[eg：this is the book （which）you want。]而且，如果which在从句中作“不及物动词＋介词”的介词的宾语，注意介词不要丢掉，而且介词总是放在关系代词which的前边，但有的则放在它原来的位置
2. which作宾语时，根据先行词与定语从句之间的语义关系，先行词与which之间的介词不能丢
3. 代表物时多用which，但在带有下列词的句子中用that而不用which，这些词包括当先行词是anything, everything, nothing , none等不定代词时，或者是由every, any, all, some, no, little, few, much等修饰时等，这时的that常被省略还有先行词前有序数词或形容词最高级修饰时,或先行词就是序数词或最高级时.以及先行词中既有人又有物时.还有句中前面有which时,都只能用that
4. who和whom引导的从句用来修饰人，分别作从句中的主语和宾语，whom作宾语时，要注意它可以作动词的宾语也可以作介词的宾语
5. whose是关系代词，修饰名词作定语，相当于所修饰成分的前置所有格.它引导的从句可以修饰人和物, 当它引导的从句修饰物体时, 可以与of which 调换,表达的意思一样。
二、关系副词（在句中作状语）
关系副词=介词+关系代词
why=for which
where=in/ at/ on/ ... which (介词同先行词搭配)
when=during/ on/ in/ ... which (介词同先行词搭配)
1. where是关系副词，用来表示地点的定语从句。
2. when引导定语从句表示时间［注］值得一提的是，表示时间“time"一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。
By the time you arrive in London, we will have stayed there for two weeks. I still remember the first time I met her. Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。
3. 当从句的逻辑主语是some, any, no, somebody, anybody, nobody, something, anything, everything或nothing时，常用there is来引导
There is somebody here who wants to speak to you. 这里有人要和你说话。
非限定性定语从句
非限定性定语从句的作用是对所修饰的成分作进一步说明，通常是引导词和先行词之间用逗号隔开，将从句拿掉后其他部分仍可成立
1. which引导的非限定性定语从句来说明前面整个句子的情况或主句的某一部分
2.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
4. 有时as也可用作关系代词
5. 在非限定性定语从句中，不能用关系副词why和关系代词that，而用who, whom代表人，用which,whose代表事物.；
注意
2.当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如：
Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。
My house, which I bought last year, has got a lovely garden.我去年买的的那幢房子带着个漂亮的花园。
This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。
3.非限制性定语从句还能将整个主句作为先行词, 对其进行修饰, 这时从句谓语动词要用第三人称单数，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。
Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。
4. 有时as也可用作关系代词
5. 在非限定性定语从句中，不能用关系副词why和关系代词that，而用who, whom代表人，用which,whose代表事物.；
关于：介词+关系词
介词+关系代词引导的定语从句关系代词在定语从句中做介词宾语时
从句常由介词+关系代词引导
(1) The school (that/which) he once studied in is very famous.
The school in which he once studied is very famous.
(2) Tomorrow I will bring here a magazine (that/which) you asked for.
Tomorrow I will bring here a magazine for which you asked.
1）介词后面的关系词不能省略。
2）that前不能有介词。
3）某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when ,where和why 互换。This is the house in which I lived two years ago.
This is the house where I lived two years ago.
Do you remember the day on which you joined our club?
Do you remember the day when you joined our club?
This is the reason why he came late. This is the reason for which he came late.
关于as/which
as,which引导的非限定性定语从句
由as, which 引导的非限定性定语从句，as和which可代整个主句，相当于and this或and that。As一般放在句首，which在句中。
As we know, smoking is harmful to one's health.The sun heats the earth, which is very important to us.
一、“as / which”特殊定语从句的先行成分
1. 形容词或形容词短语作先行成分, 具有形容词意义的介词短语也可以充当先行成分，如：My grandmother’s house was always of great importance to me, as my own is.
在一定的语言环境里，有些名词可以具有形容词的性质。这些名词主要是那些表示人的身份、职业、状态的名词。值得一提的是，在这些具有形容词性质的名词之后，引导定语从句的关系代词不能用who / whom.
2. 动词短语先行成分
这种动词短语既可是限定形式也可是非限定形式。如果是动态动词短语，它们在从句中就一般有限定或非限定形式的替代动词do和as / which一起代替。do可以出现，也可以不出现，但不能用其它动词代替。
3. 句子作先行成分
这句子可以是整个主句也可以只是主句中的一个从句。有时是连续几个句子，有时甚至可以是一个完整的故事。
二、“as/which”特殊定语从句在句中的位置
由于先行成分的构成成分不同，“as/which”特殊定语从句在句中的位置有以下几种情况：1. 形容词做先行成分时：形容词或形容词短语（含具有形容词性质的名词）作先行成分，“as / which”特殊定语从句置于先行成分之后。
2. 动词短语作先行成分时：动词短语作先行成分时，“as / which”特殊定语从句置于先行成分之后。但是，当从句中含有表示主观意志的插入成分时，“as”特殊定语从句可以移至句子之首。
3. 句子作先行成分时：“as”特殊定语从句的位置较灵活，可以置于先行成分之前、之中或之后。但如果先行成分是直接引语，“as”特殊定语从句多在先行成分之前。如果先行成分是否定句，“as”特殊定语从句与否定词的相对位置不同可以使它产生不同的意义。由于“as”特殊定语从句具有这一特点，所以有时它的位置不能随便移动。在非正式的文体里，“which”特殊定语从句可以出现在先行成分之中。
三、“as/which”特殊定语从句的语义功能
一般说来，as与which的语义功能相同，可以相互替换。但先行成分为句子时，它们的语义功能则有差异。
1. 表示结果
表示结果的特殊定语从句与其先行成分之间存在着一定的因果关系，从句中往往使用有结果意义的词，如动词result, make, enable, cause和形容词interesting, surprising, delightful, disgraceful等。
2. 表示评注
表示评注的特殊定语从句对其先行成分所述事实的正确性有肯定的倾向，它通常与那些表示客观事实，普遍真理或某种习性的先行成分连用；从句中则常用一些表示“合乎自然规律”“众所周知”或“经常发生”等意义的词语，如natural, known to all, usual等。
3. 有无状语意义
“as”特殊定语从句具有状语意义（主要是方式状语意义），而“which”特殊定语从句则无状语意义。“as”特殊定语从句的状语意义要求它在语义上与其先行成分的语义保持一致，“which”特殊定语从句则不受这种限制。
四、关系代词as与which的句法功能
1. as / which 在特殊定语从句中作主语。
as作主语时，谓语动词常为连系动词（主要是be, seem），主语补语为usual、a rule、a matter of fact等时，系动词be习惯经常省略。行为动词作“as”特殊定语从句的谓语时一般用于被动语态（其中助动词be常略），不及物的行为动词在“as”特殊定语从句中作谓语的极少，常见的有happen一词。如：
Freddie, as might be expected, was attending the conference.
Which作主语时，谓语动词不限，主语被动皆可，只是谓语动词为被动语态时助动词be省略。
2. as和which都可以在特殊定语从句中宾语。
3. as和which在特殊定语从句中作补语。如：We thought him a gentleman, as/which he could never be.
“as”特殊定语从句中可以主谓倒装，“which”从句中则不能主谓倒装。
如果先行成分不是主语补语或宾语补语，关系代词用which而不用as。如：He talked like a native, which/as he hardly was.
4. which在特殊从定语句中作定语。
which可以在特殊定语从句中作定语，修饰fact, matter, thing 等名词。这些名词代表先行成分表达的意义，有时将其略去句义仍然完整。as不能作定语。如：I was told to go not by train but bus, which advice I followed.
关于关系代词that 的用法
(1)不用that的情况
(a) 在引导非限定性定语从句时。(错)The tree, that is four hundred years old, Is very famous here.
(b) 介词后不能用。
We depend on the land from which we get our food.We depend on the land that/which we get our food from.
(2) 只能用that作为定语从句的关系代词的情况
(a)在there be 句型中，只用that，不用which。
(b)在不定代词，如：anything, nothing, the one, all, much, few, any, little等作先行词时，只用that，不用which。
(c)先行词有the only, the very,the same,the last,just修饰时，只用that。
(d)先行词为序数词、数词、形容词最高级时，只用that。.
(e)先行词既有人，又有物时。
(f) 先行词指物，在主句中作表语时．
(g) 为了避免重复．
(h)先行词是the way时
举例：Is this the book that you borrowed in the library?这是你在图书馆借的那本书吗？
Who that break the window should be punished．谁打碎了窗户都要受到惩罚．
All that is needed is a supply of oil. 所需的只是供油问题。
Finally, the their handed everything that he had stolen to the police.那贼最终把偷的全部东西交给了警察。

高考英语主语从句讲解
高考英语主语从句 定义：用作主语的从句叫主语从句，它是名词性从句之一。主语从句的时态：不受主句的时态影响和限制。引导主语从句的连接词有： 从属连词: that, whether； 连接代词: who (whoever), whom, whose, what (whatever)和which (whichever)； 连接副词: when, where, how和why。 连接词： 1. 从属连词：that，whether 1）that引导主语从句只起引导作用，在主语从句中不充当任何成分，that本身无实际意义，但不能省略。2）whether意为“是否”，放在句首句末皆可。由whether引导的名词从句做主语，表语，介词宾语，同位语时！不可用if代替。 a.That price will go up is certain. b. Whether they would support us was a problem. 他们是否会支持我们还是一个问题。 2. 连接代词who ，what ，which, whatever, whichever, whoever (Who, whom, which, what可以和ever构成合成词，和what一样引导从句，ever起到强调作用。此类主语从句不能用形式主语it引导，它们在句子中担任成分，不能省略，语序为陈述语序，既有疑问含义,又起连接作用,同时在从句中充当各种成分。 Which side will win is not clear. Whoever breaks the law will be punished. Whatever he did is right. Who killed the scientist remains a question. 1）What和that引导的主语从句的区别：that 只起引导作用，不充当任何成分，没有意思。What 不仅起引导作用，还要充当一定成分(主语、宾语或表语)，意思是：“什么”。 What we need is money. That he will come is certain. 2）whatever / whoever的用法（~ever=no matter ~---让步状语从句中） whatever / whoever可以引导主语从句,并在句中作主语、宾语、表语等,不含疑问意义。whatever相当于anything that; whoever 相当于anyone who。例如: Whoever(Anyone who) wants to enter into this school must take the exam. Whatever(Anything that) she did was right. 3. 连接副词when，where，how，why等。既有疑问含义,又起连接作用,同时在从句中充当各种成分。How this happened is not clear to anyone. When he will be back depends on the weather. When we’ll start tomorrow will be told soon. Where the test will be given is not yet decided. 4. 主语从句后置：为了避免主语冗长,句子头重脚轻,经常用it 作形式主语,主语从句放在后面作真正的主语. 例: That we shall be late is certain. -- It’s certain that we shall be late. 1）用it 作形式主语的结构 A. It + be + 形容词+ that 从句 (obvious, true, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.) 如：It is certain that she will do well in her exam. B. It + be + 名词词组+ that 从句(an honour, a fact, a pity, etc）如： It is a pity/shame that... 遗憾的是…… It is a surprise that…令人惊奇的是… It is a fact that… …是事实It is common knowledge that… …是常识 It’s a pity that we can’t go. C. It + be + 过去分词+ that 从句(said, reported, thought, expected, decided, announced, etc。）如：It is said that Mr. Green has arrived in Beijing. D. It + 不及物动词或短语+ that 从句( seem，happen, doesn’t matter ,turn out）。如： It happened that I was out that day. It doesn’t matter whether she will come or not. 2) 对于以连接代词(副词)引导的主语从句,可以使用形式主语代主语从句,也可直接在句首使用主语从

英语让步状语从句用法总结
英语让步状语从句用法总结（一） 让步状语从句的用法一（表示“虽然，即使，尽管”） 1. although，though，even though，even if都表示“虽然，即使，尽管”之意，though 和although 语气较弱(其中的though 比although 通俗, 不如although 正式)，even if和even though 带有强调意味而显得语气更强。例如：Although they are poor, they are happy. 虽然他们很穷，但很快乐。天气虽然很冷, 但他没有穿大衣就出去了。即使他们可能不会成功，但他们仍努力尝试。那篇文章虽然很短，但很重要。他好一点了，虽仍未痊愈。即使下雨，她也是走着去工作的。今晚我将去拜访他，即使我只能停留一小会儿。 注意：though 引导的让步状语从句的用法比较特殊，它可以倒装，也可以不倒装，具体用法参见as引导让步状语从句的用法。 2. as引导让步状语从句表示“虽然、即使、尽管”，其引导的让步状语从句必须采用倒装结构，as引导的倒装形式的让步状语从句的基本结构为：形容词/副词/名词(单数可数名词前一般不带冠词，有时也可见单数可数名词前形容词与不定冠词连用、形容词放在不定冠词前)/动词/过去分词＋as＋主语＋谓语的其他部分。注意体会下列典型例句：Great as the author was, he proved a bad model. 这位作者尽管了不起，到头来却成了一个坏榜样。这个故事看似荒唐，却是真的。虽然他很富有，但他并不幸福。倒装时要省去单个名词前的冠词)尽管还是个孩子，他却能分辨黑白。他尽管勇敢，可见到蛇还是发抖。尽管伤势很重，他仍然十分乐观。虽然尽了最大努力，但是他仍然不能搬动那块石头。 ［考题1］We had to wait half an hour ____ we had already booked a table. A. since B. although C. until D. before ［答案］B ［解析］下划线处之后所述的“我们已经预订了一桌”与前面所述的“我们已经不得不等了半个小时”之间语意相反，四个选项中although表示“即便……”，引导让步状语从句最为合适。 ［考题2］____ most of the earth’s surface is covered by water, fresh water is very rare and precious. A. As B. Once C. If D. Although ［答案］D ［解析］句意为：虽然地球表面覆盖着水，但是纯净水仍然很稀有、珍贵。下划线处应引导让步状语从句，填入although最为合适。 ［考题3］____ he has limited technical knowledge, the old worker has a lot of experience. A. Since B. Unless C. As D. Although ［答案］D ［解析］下划线处应引导让步状语从句，填入although最为合适。 ［考题4］Although he is considered a great writer, ____. A. his works are not widely read B. but his works are not widely read C. however his works are not widely read D. still his works are not widely read ［答案］A ［解析］英语不允许在连词although、though引导的让步状语从句之后的主句句首重复使用连词，如果要在复合句中强调某种特别的意义，可以在主句的句首加上yet、still等副词。例如：Although she has a lot of money, (yet/still) she is not happy. 虽然她很有钱，但是她并不快乐。
高中英语从句大全汇总!
01 有关概念 由一个主句和一个或一个以上从句构成的句子叫做复合句。所谓主句，就是在复合句中起统领作用 的句子，它是全句的主体，通常可以独立存在；而从句则是复合句的一个句子成分，不能独立存在。 如： You’ll feel better after you take the pills. 吃完药丸后你会感到好一些。 The police learned that he wasn’t there at that time. 警察获知他那时不在场。 这两句都是复合句，第一句的主句是You’ll feel better，从句是after you take the pills，由after 引导，在整个复合句中用作状语，表示时间；第二句的主句是The police learned是主句，that he wasn’t there at that time是从句，由that引导，在整个复合句中用作宾语。 注意，英语的复合句不是简单句的反面，不要将它误解为“复杂句”。事实上，英语的简单句有时 也可以比较“复杂”，而复合句也可以比较“简单”。如： He stopped because he was tired. 他停下来是因为他累了。 这个句子比较“简单”，却是一个典型的复合句，其中的he stopped是主句，because he was tired 是从句，在复合句中用作状语，表示原因。 02 从句的分类 前面我们说到从句是整个复合句的一个句子成分，它可以用作主语、宾语、定语、状语等。一般说 来，一个从句在复合句充当什么成分我们就叫它为什么从句——从句在复合句用作主语，我们就叫 它为主语从句；从句在复合句用作宾语，我们就叫它为宾语从句；从句在复合句用作状语，我们就 叫它为状语从句；等等。 如： He answered that he knew nothing about it. 他回答说他不知情。 The trouble is that I have lost his address. 麻烦的是我把他的地址丢了。 He was rather pleased when he won that prize. 他获奖后相当高兴。 She was not in the train that arrived just now. 她不在刚到的那列车上。
As引导让步状语从句倒装的用法
As引导让步状语从句倒装的用法 为了帮助同学们全面掌握让步状语从句的倒装用法，本文将这类语法现象归纳为以下五种句型： 一、名词+ as / though + 主语+ 动词 King as he was，he was unhappy. 他虽是国王，但他并不幸福。 Child as he is，he knows to help other. 他虽是个孩子，却知道帮助别人。 【说明】其中的动词通常为连系动词，也就是说位于句首的名词是其后连系动词的表语。另外，要特别注意位于句首的名词前习惯上不用冠词，即使其前有形容词修饰也不用冠词。比较： Boy as ［though］he is，he likes to play with girls.=Though he is a boy，he likes to play with girls. 他虽是男孩，却喜欢与女孩子玩。 Strong man as ［though］he is，General Botha has been severely put to the test during the past few weeks.= Though he is a strong man，General Botha has been severely put to the test during the past few weeks. 波赛将军虽然坚强，但在过去的数周里也受到了严峻的考验。 二、形容词+ as / though + 主语+ 动词 Successful as he is，he is not proud. 他虽然成功，但不骄傲。 Improbable as it seems，it’s true. 虽然看起来不太可能，但却是真的。 Stupid as it sounds，I was so in love with her that I believed her. 尽管听起来很愚蠢，我是如此爱她竟然相信了她的话。 Patient as he was，he didn’t like waiting that long. 他虽说有耐心，也不愿等这么长。 Beautiful though the necklace was，we thought it was over-priced. 那条项链虽然很漂亮，我们认为价钱太高。 【说明】其中的动词也通常为连系动词，也就是说位于句首的形容词是其后连系动词的表语。 三、副词+ as / though + 主语+ 动词 Much as I like Paris，I couldn’t live there. 尽管我喜欢巴黎，但我不能住在那里。 Hard though they tried，they couldn’t make her change her mind. 尽管他们做了很大努力，却没法让她改变主意。 Fast as you read，you can’t finish the book in two days. 尽管你读得很快，你总不能在两天之内就读完这本书。 He was unable to make much progress，hard as he tried. 尽管他做了努力，却未能取得很大进步。 【说明】有的词典将much as 作为习语看待，认为它是一个用以引导让步状语从句的复合连词。再如： Much as I admire him as a writer，I do not like him as a man. 他作为一名作家我很佩服他，但我却不喜欢他这个人。 Much as I like you，I couldn’t live with you. 我尽管很喜欢你，却不能和你在一起生活。 四、动词原形+ as / though + 主语+ 动词 Object as you may，I’ll go.纵使你反对，我也要去。
高中英语状语从句讲解
高中状语从句讲解+练习 状语通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3.

The moment he saw me, he ran away. 他一看见我，就跑了。 He said he’d call you the moment he got home. 他说他一到家就给你打电话 （3）The instant I saw him, I knew he was the man from the restaurant. （4）Immediately you begin to speak, he gives you his full attention.你只要一开始说话，他就全神贯注地听。 （5）My sister came directly she got my message. 我妹妹一收到我的信息就来了。 （6）Every time I listen to your advice, I get into trouble. （7）no sooner... than... ，"一...就..." ，引导时间状语从句,主句用过去完成时,"than"后面的从句用一般过去时.(从这里可以知道,no sooner后面是主句;than后面是从句) 例: I had no sooner reached home than it began to rain. 我一到家天就下起雨来 No sooner ...than...常放在句首,表示强调.这时主句要倒装. 例:No sooner had I reached home than it began to rain. （8）He had hardly sat down when the telephone rang.他刚坐下电话就响了。 He had scarcely sat down when there was a knock at the door. 他刚坐下就有人敲门 另外，如果把hardly放于句首，主句要用倒装结构。如： Hardly had I finished eating when he came in. 我刚吃完他就进来了。 2．地点状语从句 常用引导词：where 特殊引导词：wherever, anywhere, everywhere Generally, air will be heavily polluted where there are factories.
