❶ 英語中從句的語法大全
英語中六大從句用法總結
1.主語從句
1）主語從句可直接位於主語的位置，如果從句較長，謂語又較短，可用it作形式主語，而將從句放在句末。常見的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引導的主語從句表示「...的東西時」，一般不用it作形式主語。
What we lack is experience.
3)what,who,when,why,whether等詞含有各自的疑問意義，但它們引導的主語從句，都用陳述語序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.賓語從句
1）賓語從句可位於及物動詞、介詞和某些形容詞後。連詞that常可省略。介詞後一般接疑問詞引導的賓語從句。in that(因為),except that(除了),but that(只是）已構成固定搭配，其他介詞後一般不接that引導的賓語從句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)賓語從句後如有賓補，要用形式賓語it來代替，而把賓語從句移至賓補之後。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等動詞後的賓語從句中，如果謂語是否定的，一般將否定詞移至主句謂語上，賓語從句則變成肯定形式。
He didn't think that the money was well spent.
3.表語從句
表語從句出現在結構為「主語+系動詞+表語從句」的句子中。表語從句除可用that,what,when,why,whether,how等引導外，還可由because,as if(though)等引導。that常可省略。如主句主語為reason,只能用that引導表語從句，不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位語從句
同位語從句用於對前面出現的名詞作進一步說明，一般用連詞that引導，由於先行名詞的意義不同，也可用whether,who,when,where,what,why,how等引導。常見的先行名詞有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有時由於謂語較短，將同位語從句位於謂語之後。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定語從句
定語從句所修飾的先行詞可以是名詞或代詞，也可以是一個句子。定語從句通常位於先行詞之後，由關系代詞或關系副詞引導。
*限制性定語從句
限制性定語從句修飾先行詞，對先行詞起修飾作用，緊接先行詞之後，無逗號，若省去，原句意思不完整。引導定語從句的關系代詞有who,whom,whose,which,that等。who,whom,whose用於指人，whose有時也可指物，相當於of which；which用於指物；that既可指人也可指物，但只用於限制性定語從句中。關系代詞除了引導定語從句，替代先行詞外，還在從句中擔任主語、賓語、定語等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)當先行詞是all,anything,everything,something,nothing等不定代詞或先行詞前有first,last,any,few,much,some,no,only以及形容詞最高級修飾時，只能用關系代詞that引導從句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)關系代詞的省略
在從句中作賓語的關系代詞常可省略。關系代詞緊跟介詞，作介詞賓語時不可用that，只可用which或whom引導從句，並且不可省略，但當介詞位於賓語從句句末時，作為介詞賓語的關系代詞仍可用that，也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引導定語從句的關系副詞有when,where,why等。關系副詞在從句中作狀語，意義上相當於一個「介詞+which」的結構。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定語從句
*非限制性定語從句
非限制性定語從句既可修飾先行詞，也可修飾整個主句，起補充說明作用，與主句之間有逗號隔開，若省去，原句意思不受影響。不可用that引導非限制性定語從句。關系詞不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*「介詞+which\whom\whose」引導的定語從句
「介詞+which\whom\whose」可引導限制性定語從句，也可引導非限制性定語從句，該結構中介詞的選擇取決於從句謂語動詞的固定搭配，或先行詞的習慣搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引導的定語從句
as引導的定語從句主要用於「such...as」及「the same...as」的結構中，代替先行詞是人或物的名詞。as引導非限制性定語從句時，代替整個主句，從句可位於主句之前、之後或中間。
These are not such problems as can be easily solved.(as代替先行詞problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主語)
6.狀語從句
*時間狀語從句
引導時間狀語從句的從屬連詞和片語有：
1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。
As soon as I sent an e-mail message,I received positive responses.
The moment he heard the good news,he jumped with joy.
*地點狀語從句
引導地點狀語從句的連詞是where,wherever.
Wherever she went,she took her little daughter with her.
*原因、結果和目的狀語從句
1）引導原因狀語從句的從屬連詞有：because,as,since,now(that),seeing that,considering that,in that等。
Considering that he is a freshman,we must say he is doing well.
2)引導結果狀語從句的連詞有：so...that,such...that
,so that,that,so等。
Mickey Mouse is so attractive that the children are reluctant to leave.
3)引導目的狀語從句的連詞有：so that,in order that,for fear that,lest等，從句常使用may,might,can,could,would等情態動詞。
We got up early this morning so that we could catch the first bus to the railway station.
*條件和讓步狀語從句
1）引導條件狀語從句的連詞和片語有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引導讓步狀語從句的連詞和片語有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引導狀語從句可轉換成含有as的部分倒裝結構，具有強調意義。其結構為「形容詞（副詞、動詞、名詞）+as+主語+謂語」。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式狀語從句
引導方式狀語從句的連詞有as,just as,as if,as though等。as if,as though引導的狀語從句中，謂語動詞常用虛擬語氣，表示與事實相反。
The young man made the experiment just as the teacher had taught him.
Everything went on as usual as if nothing had happened.
❷ 英語中的定語從語，賓語從句，狀語從句的詳解
定語從句就是一個從句在整個句子中充當定語的成分
賓語從句就是一個從句在整個句子中充當賓語的成分
狀語從句就是一個從句在整個句子中充當狀語的成分
定語從句
（一）、定義：在復合句中，修飾某一名詞或代詞的從句叫做定語從句。
定語 定語用來限定、修飾名詞或代詞的，是對名詞或代詞起修飾、限定作用的詞、短語（動詞不定式短語、動名詞短語和分詞短語）或句子，漢語中常用『……的』表示。主要由形容詞擔任，此外，名詞，代詞，數詞，分詞，副詞，不定式以及介詞短語也可以來擔任，也可以由一個句子來擔任。單詞作定語時通常放在它所修飾的詞之前，作前置定語。短語和從句作定語時則放在所修飾的詞之後，作後置定語。
定語從句是指在一個句子中作定語的句子，定語從句要放在所修飾的詞後。
如：1) The man who lives next to us is a policeman.
2) You must do everything that I do.
上面兩句中的man和everything是定語從句所修飾的詞，叫先行詞，定語從句放在先行詞的後面。
引導定語從句的詞有關系代詞that, which, who(賓格who, 所有格whose)和關系副詞where, when、why
關系詞常有三個作用：1、引導定語從句 2、代替先行詞 3、在定語從句中擔當一個成分
（二）、關系代詞引導的定語從句
1.who指人，在從句中做主語
(1)The boys who are playing football are from Class One.
(2)Yesterday I helped an old man who lost his way.
2. whom指人，在定語從句中充當賓語，常可省略。
(1) Mr. Liu is the person (whom) you talked about.
注意：關系代詞whom在口語和非正式語體中常用who代替，可省略。
(3) The man who/whom you met just now is my friend.
3. which指物，在定語從句中做主語或者賓語，做賓語時可省略
(1) Football is a game which is liked by most boys. ( which 在句子中做主語)
(2) This is the pen (which) he bought yesterday. ( which 在句子中做賓語)
4. that指人時，相當於who或者whom；指物時，相當於which。
在賓語從句中做主語或者賓語，做賓語時可省略。
(5) The people that/who come to visit the city are all here. (在句子中做主語)
(6) Where is the man that/whom I saw this morning? (在句子中做賓語)
5. whose通常指人，也可指物，在定語從句中做定語
(1) He has a friend whose father is a doctor.
(2) I lived in a house whose roof has fallen in.
whose指物時，常用以下結構來代替
(3)The classroom whose door is broken will soon be repaired.
=The classroom the door of which is broken will soon be repaired.
(5)Do you like the book whose color is yellow?
=Do you like the book the color of which is yellow?
註：that 用法
(1)不用that的情況
(a) 在引導非限定性定語從句時。
(錯)The tree, that is four hundred years old, is very famous here.
(b) 介詞後不能用。
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作為定語從句的關系代詞的情況
(a) 在there be 句型中，只用that，不用which。
(b) 在不定代詞，如：anything, nothing, the one, all等作先行詞時，只用that，不用which。
(c) 先行詞有the only, the very,the same,the last,just修飾時，只用that。
(d) 先行詞為序數詞、數詞、形容詞最高級時，只用that,不能用which。.
(e) 先行詞既有人，又有物時。
(f) 先行詞指物，在主句中作表語時．
(g) 為了避免重復．
(h)先行詞是the way或the reason時，that可作關系副詞，也可省略
(i) 主句的主語是疑問詞who /which時
舉例：
Is this the book that you borrowed in the library?
這是你在圖書館借的那本書嗎？
Who that break the window should be punished．
誰打碎了窗戶都要受到懲罰．
All that is needed is a supply of oil.
所需的只是供油問題。
Finally, the thief handed everything that he had stolen to the police.
那賊最終把偷的全部東西交給了警察。
（三）、關系副詞引導定語從句
關系副詞 關系副詞：在句中作狀語
關系副詞=介詞+關系代詞
why=for which
where=in/ at/ on/ ... which (介詞同先行詞搭配)
when=ring/ on/ in/ ... which (介詞同先行詞搭配)
1. where指地點，在定語從句中做地點狀語用來表示地點的定語從句。
(1) Shanghai is the city where I was born.
(2) The house where I lived ten years ago has been pulled down.
2. when引導定語從句表示時間。在定語從句中做時間狀語也可做連接詞用
(1) I still remember the day when I first came to the school.
(2) The time when we got together finally came.
[注]表示時間「time"一詞的定語從句只用when引導，有時不用任何關系代詞，當然也不用that引導。
By the time you arrived in London, we had stayed there for two weeks.
到你到達倫敦的時候，我們在那裡已經待了兩個星期。
I still remember the first time I met her. 我仍然記得我第一次見到她。
Each time he goes to business trip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。
每一次他去出差，他帶來了生活必需品，如毛巾，肥皂，牙刷等，很多。
3. why指原因 在定語從句中做原因狀語
(1) Please tell me the reason why you missed the plane.
(2) I don』t know the reason why he looks unhappy today.
注意：關系副詞引導的從句可以由「介詞+關系代詞」引導的從句替換
(1) The reason why/ for which he refused the invitation is not clear,
(2) From the year when/in which he was going to school, he began to know what he wanted when he grew up.
註：1）介詞後面的關系代詞不能省略。
2）that前不能有介詞。
3） 某些在從句中充當時間，地點或原因狀語的"介詞+關系詞"結構可以同
關系副詞when ,where和why 互換。
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.
賓語從句
（一） 賓語從句的種類
賓語從句是一種名詞性從句，在句中作及物動詞的賓語，或介詞的賓語，或形容詞的賓語。根據引導賓語從句的不同連詞，賓語從句可分為三類。
1. 由that引導的賓語從句。that只有語法作用，沒有實在的意義，在口語
和非正式文體中可以省略。例如：
He said (that) he wanted to stay at home.
She doesn』t know (that) she is seriously ill.
I am sure (that) he will succeed.
2. 由連接代詞who, whom, whose, what, which和連接副詞when, where, why, how引導的賓語從句。這些連接代詞和連接副詞在賓語從句中充當某個成分。例如：
Do you know who (whom) they are waiting foe?
He asked whose handwriting was the best.
Can you tell me where the No.3 bus stop is?
I don』t know why the train is late.
3. 由if或whether引導的賓語從句。if和whether在句中的意思是「是否」。例如：
I want to know if (whether) he lives there.
He asked me whether (if) I could help him.
（二）賓語從句的語序
賓語從句的語序應為陳述句的語序。例如：
I hear (that) physics isn』t easy.
I think (that) you will like this school soon.
Can you tell me how I can get to zoo?
Please tell me when we』ll have the meeting.
（三）賓語從句的時態
1. 如果主句的時態是一般現在時，賓語從句該用什麽時態就用什麽時態。
如： I don』t think (that) you are right.
Please tell us where he is.
Can you tell me how I can get to the railway station?
2. 如果主句的時態是一般過去時，賓語從句只能用相應的過去時態（一般過去時， 過去進行時， 過去將來時，過去完成時）。例如：
He asked what time it was.
He told me that he was preparing for the sports meet.
He asked if you had written to Peter.
He said that he would go back to the U.S. soon.
3. 如果賓語從句所陳述的是客觀真理，其時態常用一般現在時。例如：
Our teacher said that January is the first month of the year.
Scientists have proved that the earth turns around the sun.
狀語從句
狀語從句
狀語從句用來修飾主句中的動詞，副詞和形容詞的從句叫狀語從句。根據其含義狀語從句可分為時間狀語從句，地點狀語從句，條件狀語從句， 原因狀語從句，結果狀語從句，比較狀語從句，目的狀語從句，讓步狀語從句。
1. 時間狀語從句
(1)時間狀語從句常用when, as, while, before, after, since, till, until, as soon as等連詞來引導。例如：
It was raining hard（rain hard 下大雨） when got to school yesterday.
While he was doing his homework, the telephone rang.
As he walked along（沿著走） 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)在時間狀語從句里，通常不用將來時態，用現在時態表示將來的動作或狀態。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)在帶有till或until引導的時間狀語從句的主從復合句里，如果主句用肯定式，其含義是「一直到……時」，謂語動詞只能用延續性動詞。如果主句用否定式，其含義是「直到……才……」, 「在……以前不……」, 謂語動詞可用瞬間動詞。例如：
The young man read till the light went out（熄滅）.
Let』s wait until the rain stops.
We won』t start until Bob comes.
Don』t get off（從下來） until the bus stops.
【Till是指直到某一特定事件發生的時候，而在那個時刻之後，該事情或狀況仍將持續。 Until是指直到某一特定事件發生的時候，而講話的人在自己心裡認為，在那個時刻之後，該事情或該狀況將中止（不怎麼可能持續）。固定組合里from morning till night，till/until是不能替換的，】
2. 條件狀語從句
(1)條件狀語從句通常由if, unless引導。例如：
What shall we do if it snows tomorrow?
Don』t leave the building unless I tell you to.
(2)在條件狀語從句里，謂語動詞通常用現在時態表示將來的動作或狀態。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)+ 陳述句」 在意思上相當於一個帶有條件狀語從句的復合句。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. 原因狀語從句
(1)原因狀語從句通常由because, since, as引導。例如：
He didn』t come to school because he was ill.
As it is raining, we shall not （不得；不應該）go the zoo.
Since you can』t answer the question, I』ll ask someone else.
(2)because表示直接原因，語氣最強。Because引導的原因狀語從句多放在主句之後。回答由why提出的問題，只能用because。As和since語氣較弱，一般用來表示明顯的原因。由as和since引導的原因狀語從居多放在句首。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不能同用在一個句子里。
4. 結果狀語從句
(1)結果狀語從句由so…that, such…that, so that引導。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語such...that可以互換。例如：
在由so...that引導的結果狀語從句中，so是副詞，與形容詞連用。其結構是: 「...so + 形容詞（副詞）+ that + 從句」。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（幾乎不，從來不） see her.
在由such…that引導的結果狀語從句中，such是形容詞，它修飾的可以是單數或復數可數名詞，也可以是不可數名詞；名詞前面可以帶形容詞，也可不帶。如果是單數可數名詞，前面需加不定冠詞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.（天花板）
He made such rapid progress that he did very well in the mid-term.
有時上述兩種結構是可以互換的。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)如果名詞前由many, much, little, few等詞修飾時，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（去看電影） with you.
5. 比較狀語從句
比較狀語從句通常由as…as, 比較級 + than…等連詞引導。例如：
Tom runs faster than John does.
This classroom is as big as that one.
6. 目的狀語從句
(1)目的狀語從句通常由 so that, in order that（為了，以便）引導。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既可引導目的狀語從句，又可引導結果狀語從句。區別這兩種從句的辦法有兩個：1)目的狀語從句里往往帶有情態動詞can, could, may, might等。2)從意思上看，目的狀語從句往往表示的目的很明確。例如：
Speak clearly so that they may understand you. (目的狀語從句)
Jack is badly ill so that he has to rest. (結果狀語從句)
7. 讓步狀語從句
(1)讓步狀語從句通常由although, though等連詞引導。例如：
Though he is young, he knows a lot.
Although I am tired, I must go on working.
(2)although(though)不能用在同一個句子中。例如：
我們不能說：Though it was raining hard, but he still went out.
應該說：Though it was raining hard, he still went out.或It was raining hard, but he still went out.
8. 地點狀語從句
地點狀語從句常常由where來引導。例如：
Go where you like.
Where there is a will, there is a way.
總結：狀語從句分類及常用連詞：
類別連詞
時間狀語從句when, whenever, while, as, before, after, since, till, once（一旦）
地點狀語從句where, wherever
原因狀語從句because, since, as, for, now that（既然，由於）etc. （et cetera，等於and so on）
目的狀語從句in order that(為了，以便), so that, that, etc.
結果狀語從句so…that, so that, such…that, that, etc.
條件狀語從句if, unless, as(so)long as, etc.
讓步狀語從句though, although, even if, even though, however, whatever, as, etc.
比較狀語從句as…as, so…as, than, etc.
方式狀語從句as, as if, as though, etc.
❸ 英語語法中的從句
大致有下面幾種（以下是我個人總結的，僅供參考）：
一、名詞性從句
其中又包括主語從句、同位語從句、賓語從句、表語從句
What I have is only a piece of bread.(What引導的主語從句)
News spread in the village that he came back.(that引導的同位語從句)
I think that you are right.(that引導的賓語從句)
What I appreciate is that you are brave.(that引導的標語從句)
二、形容詞性從句
也就是定語從句
The mountain is beautiful from the top of which we can see our school.(which 引導的定語從句)
三、狀語從句
主要有時間狀語從句、地點狀語從句、原因狀語從句、條件狀語從句、目的狀語從句、讓步狀語從句、比較狀語從句、程度狀語從句、方式狀語從句、結果狀語從句
I will call you as soon as I arrive in Beijing. （as soon as引導的時間狀語從句）
You should have put the book where you found it.(where引導的地點狀語從句)
I hate you because you hurt me.(because 引導的原因狀語從句)
If it is convenient,I will help you.(if引導的條件狀語從句)
You must speak louder so that you can be heard.（so that 引導的目的狀語從句）
She passed the examination though she had not studied very hard.(though引導的讓步狀語從句)
She finds it easier to read than to write．（than引導的比較狀語從句）
❹ 英語語法中什麼是從句，賓語從句壯語從句和其他從句呢解釋清楚點謝謝。通俗點也沒關系能懂就行了，最...
答：從句與主句的關系，好比是子公司和總公司的關系。一個公司有經理和工作人員。一個句子有主語和謂語兩部分組成。子公司是總公司的一個組成部分。從句是主句中的一個句子成分。按功能分，有名詞性從句（包括主語從句、賓語從句、表語從句和同位語從句）、形容詞性從句（即定語從句）和副詞性從句（即狀語從句），按句子成分分有主、賓、表、同、定、狀語從句
例：That the earth goes around the sun is know to us all. 主語從句。
We all know that the earth goes around the sun. 賓語從句。
What we all know is that the earth goes around the sun. 主語從句， 表語從句。
The fact that the earth goes aroung the sun is known to us all. 同位語從句。
This is the best film I have even seen. 定語從句。
Where there is a river, there is a big city. 狀語從句。
❺ 英語語法中從句有幾種，要詳細的。
英語中六大從句用法總結
1.主語從句
1）主語從句可直接位於主語的位置，如果從句較長，謂語又較短，可用it作形式主語，而將從句放在句末。常見的句型有：
*It is a fact\a pity\a question\good news that...
*It seems\appears\happened\has turned out that...
*It is clear\important\likely\possible that...
*It is said\reported\estimated\has been proved that...
It is said that comic books create a connection between people of the same generation.
It seems that the performance is very useful.
2)what引導的主語從句表示「...的東西時」，一般不用it作形式主語。
What we lack is experience.
3)what,who,when,why,whether等詞含有各自的疑問意義，但它們引導的主語從句，都用陳述語序。
How the plan is to be carried out should be discussed again.
I did know why I felt like crying.
2.賓語從句
1）賓語從句可位於及物動詞、介詞和某些形容詞後。連詞that常可省略。介詞後一般接疑問詞引導的賓語從句。in that(因為),except that(除了),but that(只是）已構成固定搭配，其他介詞後一般不接that引導的賓語從句。
*I promised that I would change the situation.
*All this is different from what American young people would say about friendship.
*He is certain that watching so much television is not good for children.
*This article is well-written except that it is a bit too long.
2)賓語從句後如有賓補，要用形式賓語it來代替，而把賓語從句移至賓補之後。
He has made it clear that he would not change his mind.
3)在think,believe,suppose,expect等動詞後的賓語從句中，如果謂語是否定的，一般將否定詞移至主句謂語上，賓語從句則變成肯定形式。
He didn't think that the money was well spent.
3.表語從句
表語從句出現在結構為「主語+系動詞+表語從句」的句子中。表語從句除可用that,what,when,why,whether,how等引導外，還可由because,as if(though)等引導。that常可省略。如主句主語為reason,只能用that引導表語從句，不可用because.
Perhaps the most important thing to remember is that there is no one common type of life in America.
The reason why so many people died there is that there were not enough food supplies.
It looks as if successful international cultural communication will make the world smaller.
4.同位語從句
同位語從句用於對前面出現的名詞作進一步說明，一般用連詞that引導，由於先行名詞的意義不同，也可用whether,who,when,where,what,why,how等引導。常見的先行名詞有fact,idea,belief,news,hope,conclusion,evidence,suggestion,order,problem,report,decision.有時由於謂語較短，將同位語從句位於謂語之後。
She finally made the decision that she would join the fashion show.
I had no idea how many books I could borrow at a time.
The news came that their team had won the championship.
5.定語從句
定語從句所修飾的先行詞可以是名詞或代詞，也可以是一個句子。定語從句通常位於先行詞之後，由關系代詞或關系副詞引導。
*限制性定語從句
限制性定語從句修飾先行詞，對先行詞起修飾作用，緊接先行詞之後，無逗號，若省去，原句意思不完整。引導定語從句的關系代詞有who,whom,whose,which,that等。who,whom,whose用於指人，whose有時也可指物，相當於of which；which用於指物；that既可指人也可指物，但只用於限制性定語從句中。關系代詞除了引導定語從句，替代先行詞外，還在從句中擔任主語、賓語、定語等。
The computers and cables which make up the Internet are owned by people and organizations.
Those who live alone or who are sick may have trouble in getting close to other people.
The girl whose parents died in an accident is living with her grandmother.
1)當先行詞是all,anything,everything,something,nothing等不定代詞或先行詞前有first,last,any,few,much,some,no,only以及形容詞最高級修飾時，只能用關系代詞that引導從句。
That is all that I've heard from him.
He's the first person that I'm going to interview this afternoon.
2)關系代詞的省略
在從句中作賓語的關系代詞常可省略。關系代詞緊跟介詞，作介詞賓語時不可用that，只可用which或whom引導從句，並且不可省略，但當介詞位於賓語從句句末時，作為介詞賓語的關系代詞仍可用that，也可省略。
This is one of those things with which we have to put up.
This is one of those things (which\that) we have to put up with.
3)引導定語從句的關系副詞有when,where,why等。關系副詞在從句中作狀語，意義上相當於一個「介詞+which」的結構。
Even in comic books where(=in which) there are no words,the stories are fully expressed through the drawings.
No one knows the reason why(=for which) he was so angry that day.
5.定語從句
*非限制性定語從句
非限制性定語從句既可修飾先行詞，也可修飾整個主句，起補充說明作用，與主句之間有逗號隔開，若省去，原句意思不受影響。不可用that引導非限制性定語從句。關系詞不可省略。
Every object has a gravitational pull,which is rather like magnetism.
*「介詞+which\whom\whose」引導的定語從句
「介詞+which\whom\whose」可引導限制性定語從句，也可引導非限制性定語從句，該結構中介詞的選擇取決於從句謂語動詞的固定搭配，或先行詞的習慣搭配。
This is the computer on which he spent all his savings
It is written by a person with whom we are all familiar.
*as引導的定語從句
as引導的定語從句主要用於「such...as」及「the same...as」的結構中，代替先行詞是人或物的名詞。as引導非限制性定語從句時，代替整個主句，從句可位於主句之前、之後或中間。
These are not such problems as can be easily solved.(as代替先行詞problems)
As is mentioned above,no single company or group can control what happens on the Internet.(as代替主語)
6.狀語從句
*時間狀語從句
引導時間狀語從句的從屬連詞和片語有：
1）when,whenever,while,as,after,before,since,till,until,once等。
We have learnt quite a lot about it since we came here.
2)as soon as,hardly(scarcely)...when,no sooner...than,each(every) time,the moment,immediately(that)等。

*條件和讓步狀語從句
1）引導條件狀語從句的連詞和片語有if,unless,as(so) long as,on condition that,in case,provided(providing) that,supposing等。
As long as you have the right equipment,you can use a telephone line to transmit computer data.
2)引導讓步狀語從句的連詞和片語有though,although,whether,even though,even if,no matter what(when,how...),whatever(whenever,wherever,however....)等。though,even if等引導狀語從句可轉換成含有as的部分倒裝結構，具有強調意義。其結構為「形容詞（副詞、動詞、名詞）+as+主語+謂語」。
No matter what you may say,I would not change my mind.
Young as he is,he is quite experienced in this work.(=though he is young)
Child as he is,he can speak English fluently.(=though he is a child)
*方式狀語從句
引導方式狀語從句的連詞有as,just as,as if,as though等。as if,as though引導的狀語從句中，謂語動詞常用虛擬語氣，表示與事實相反。

❽ 高中的英語語法，從句部分的講解
高三英語語法重點難點點撥 <<陳老師課堂>>
高中英語狀語從句講解
一．原因從句
1. 由as／because／since 引導的原因從句：
We camped there as／because／since it was too dark to go on．我們在那裡露宿是因為天太黑，不能再繼續往前走了。
As／Because／Since it was too dark to go on，we camped there．因為天太黑不能再繼續往前走，我們就在那兒露宿了。
2. in view of the fact that可用as／since／seeing that來表示，但不能用because： As／Since／Seeing that you are here，you may as well give me a hand．既然你在這兒，就幫我個忙吧。
As／Since／Seeing that Tom knows French，he』d better do the talking．既然湯姆懂法語，最好讓他來談。
二．結果從句
結果狀語從句——引導結果狀語從句的連詞有：so that, so…that, such that, such…that, that等。當從句前面有逗號時，so that中that可省略，如：
It was dark, so (that) we could see nothing in front of us.
「So + 形容詞 / 副詞 + that」是引導結果狀語從句的常用結構，如：
He talked so loud that he annoyed the speaker. He was so brilliant that he made a lot of inventions.
「such (a) + 形容詞 + 名詞 + that」與「so…that」的意義相同，如：
It was such a hot day that people could not go out. He painted such beautiful pictures that the visitors were lost in admiration.
such／so…that引導的結果從句
A such是形容詞，用於形容詞+名詞結構之前：
They had such a fierce dog that no one dared to go near their house．他們有一條如此兇猛的狗，以致沒人敢靠近他們家。
He spoke for such a long time that people began to fall asleep．他說了這么長時間，以致在座的人都犯困了。
B so是副詞，用於副詞和不帶名詞的形容詞之前：
The snow fell so fast that our footsteps were soon covered up．雪下得這么快，以致我們的腳印很快就被雪蓋住了。
His speech went on for so long that people began to fall asleep．他的講話這么長，以致在座的人都開始犯困了。
Their dog was so fierce that no one dared come near it．他們的狗太兇猛了，所以沒人敢靠近它。
such不能用於much和many之前，so可用於後跟名詞的much和many之前：
There was so much st that we couldn』t see what was happening．灰塵太大了，使得我們看不清發生了什麼事。
So many people complained that they took the programme off．抱怨的人太多，所以他們取消了那個節目。
C 注意：such＋a＋形容詞＋名詞可由so＋形容詞＋a＋名詞來代替，所以such a good man可由so good a man來代替。這只能在名詞前面有a／an的情況下使用。
熱點之一：含有否定意義的副詞放在句首引起的部分倒裝
此類副詞有：not，never，seldom，hardly，rarely，little等。例如：
Not a single word did he say at the meeting．（在會上，他什麼也沒說。）
熱點之二：含有否定意義的連接詞置於句首引起的部分倒裝
此類連接詞有：not only．．．but also，neither．．．nor．．．，no sooner．．．than，scarcely．．．when，hardly．．．when等。請看例句：
No sooner had she gone out than the telephone rang．（她一出門電話就響了。）
熱點之三：搞清so（nor ，neither）＋助動詞＋主語與so（nor ，neither）＋主語＋助動詞之間的區別
前者表示重復前句部分的內容，譯為「也是如此」。而後者表示對前句內容的進一步肯定或證實，譯為「確實如此」。例如：
Lily can't answer the question．Neither can I．莉莉不能回答這問題。我也不能。
Tom was late for school yesterday．So he was. 湯姆昨天上學遲到。他確實如此。
熱點之四：省略if的虛擬條件句以had ／were ／should開頭引起的部分倒裝
這是虛擬語氣中比較特殊的一種，其實質就是省略if後引起的變化。如：
Had he worked harder，he would have got through the exams．（要是他努力學習的話，他是會通過考試的。）
熱點之五：not until置於句首引起後面句子的部分倒裝
not until意為「直到……才……」，位於句首時引起後面的主句倒裝。如：
Not until the teacher came did he finish his homework．老師來了他才完成作業。
熱點之六：only短語置於句首引起的部分倒裝
only放在句首，修飾副詞、介詞短語或狀語從句，常引起後面句子部分倒裝。如：
Only in this way can you learn English well．只有通過這種方式，你才能把英語學好。
讓步從句
它們由下列詞來引導：although，though，even though，even if，no matter，however有時也可以使用whatever。as也可以，但是只限於形容詞＋as＋be結構。
Although／Though／Even though／Even if you don』t like him you can still be polite．盡管／即使／縱然／即使你不喜歡他，你仍可有禮貌一些。
No matter what you do，don』t touch this switch．無論怎樣，都別碰這個按鈕。
However rich people are，they always seem anxious to make more money．無論人們多麼富有，他們似乎總還渴望賺到更多的錢。
However carefully you drive，you will probably have an accident eventually．無論你開車多小心，最後你大概還會出車禍。
Whatever you do，don』t tell him that I told you this．無論如何，別跟他說這件事是我告訴你的。
Patient as he was，he had no intention of waiting for three hours．哪怕他再有耐心，也不打算等上三個小時。
比較從句
He didn』t play as well as we expected／as well as you（did）．他打得不如我們預料的好／你打得好。
He sings more loudly than anyone I』ve ever heard／than anyone else （does）．他唱得比我聽到的任何人唱得都響／比任何人都聲音響。
You work harder than he does／than him／than I did at your age．你比他幹得賣勁／我在你這個年齡時幹得賣勁。
時間從句
A 時間從句由下列表示時間的連詞來引導：
after immediately till／until no sooner…than when as soon as since whenever before the sooner while hardly…when the minute the moment
B 時間從句中不用將來時態。
1 如將下列將來時態放入時間從句中，須將它變為一般時態。
You』ll be back soon．I』ll stay till then．= I』ll stay till you get back．你會很快回來，我一直等到那時。
C since從句
since從句後面常跟完成時態
They』ve moved house twice since they got married．／Since they got married，they』ve moved house twice．他們結婚後已搬了兩次家。
He said he』d lived in a tent since his house burnt down．他說自從他的房屋被燒毀後，他就一直住在帳篷里。
It』s ages since I sailed／have sailed a boat．我未駕駛帆船已有好多年了。
I haven』t sailed a boat since I left college．自從我大學畢業後就沒再駕駛帆船了。
D after從句
after從句之後常跟完成時態：
After／When he had rung off I remembered… 等他把電話掛斷後，我才想起……
After／When you』ve finished with it，hang it up．你用完了之後，請把它掛起來。
E hardly／scarcely… when，no sooner… than
The performance had hardly begun when the lights went out．= Hardly had the performance begun when the lights went out．演出剛開始就停電了。
這里可以用scarcely代替hardly，但不常見。
He had no sooner drunk the coffee than he began to feel drowsy．= No sooner had he drunk the coffee than he began to feel drowsy．他喝咖啡沒多一會兒，就犯困了。
He no sooner earns any money than he spends it．= Immediately he earns any money he spends it．他錢一掙到手，就花光了。
注意the sooner…the sooner的用法：
The sooner we start，the sooner we』ll be there．我們動身得越早，到那兒就越早。
