英語中的從句語法

Ⅰ 英語中從句有幾種類型

英語中從句有6類，分別為：主語從句、表語從句、賓語從句、同位語從句、定語從句和狀語從句。

1、主語從句（Subject Clause）

用作主語的從句叫主語從句。引導主語從句的關聯詞有從屬連詞、疑問代詞、疑問副詞、縮合連接代詞、縮合連接副詞等。

2、表語從句（Predicative Clause）

用作表語的從句叫做表語從句。引導表語從句的關聯詞與引導主語從句的關聯詞很多都一樣。

3、賓語從句（Object Clause）

在句子中起賓語作用的從句叫做賓語從句。賓語從句分為三類：動詞的賓語從句、介詞的賓語從句和形容詞的賓語從句。

4、同位語從句

是名詞性從句(主語從句、表語從句、賓語從句、同位語從句)中的主要從句之一，從句作同位語表示與之同位的名詞(短語)的實際內容，它的作用相當於名詞，對前面的名詞(短語)加以補充說明或進一步解釋，相當於一個表語從句，它們之間的關系就是同位關系，即主表關系。

5、定語從句

是由關系代詞或關系副詞引導的從句，其作用是作定語修飾主句的某個名詞性成分，相當於形容詞，所以又稱為形容詞性從句，緊跟在它所修飾的先行詞後面。

6、狀語從句

用作狀語的從句叫作狀語從句，其關聯詞是一些從屬連詞。修飾主句中的動詞、形容詞和副詞，通常由從屬連詞引導，按其意義和作用可分為時間、地點、 條件、 原因、讓步、目的、結果、 方式、比較狀語從句等。

Ⅱ 英語語法中的 關系從句 和 從屬從句 有什麼區別

1. 英語中的關系詞，指的就是定語從句中的連接主句和從句的中間的那個代詞或副詞，具體相關的定義如下：
復合句中，用一個句子作定語修飾某一名詞或代詞，有時也可以用來修飾一個名詞性短語，也可以修飾一個句子，這樣的從句叫定語從句(attributive clause)。定語從句修飾的詞叫做先行詞或中心詞(antecedent)；連接定語從句的詞叫關系詞(relative)。先行詞與關系詞之間實質上是互等關系。也就是說，關系詞的作用就是將先行詞所表達的意義代到從句中來起作用。定語從句必須放在先行詞/中心詞之後，而引導定語從句的詞有關系代詞：as, that, which, who, whom, whose(特殊句式中but, than也作關系代詞)和關系副詞：when,where, why等。
This is the house where/in which we lived last year.這就是我們去年住的房子。
I still remember the day when/on which I first came to Beijing.我仍記得第一次去北京的那一天。
His parents wouldn't let him marry anyone whose family was poor.他父母不讓他和家庭困難的人結婚。
Finally, the thief handed everything (that) he had stolen to thepolice.最後，那個小偷向警察交出他偷的所有的東西。
In the dark street, there wasn't a single person to whom she could turnfor help.在那個黑暗的街道上，沒有她可以求助的人。
In 1519 another traveler who went to America from Europe discoveredthe tomato.1519年另一位從歐洲去美洲的旅行家發現了西紅柿。

2. 從屬從句的概念就比較廣了，名詞性從句的主語從句、表語從句、賓語從句、同位語從句；起副詞作用的狀語從句；起定語作用的定語從句。這些都是從屬從句。
引導主語從句的關聯詞有三類：
(1) 從屬連詞that，放於句首，不可省略，用形式主語it的主語從句中口語中可以省略that。
That they were in truth sisters was clearfrom the facial resemblance between them.很明顯，她們確是親姐妹，她們的臉型很相似。
→It was clear from the facial resemblance between them (that) theywere in truth sisters.
(2) 從屬連詞whether(不可以用if)表示「是否」。
Whether he'll come here isn't clear.他是否會來這里還不清楚。
(3) 連接代詞what, whatever, which, whichever, who, whom, whoever, whose等。
(4) 連接副詞how,when, where, why等。
Whoever comes is welcome.不論誰來都歡迎。
What she did is not yet known.她幹了什麼尚不清楚。
How this happened is not clear to anyone.這事怎樣發生的，誰也不清楚。
Wherever you are is my home - my only home.你所在的任何地方就是我的家—我唯一的家。

3. 狀語從句根據它們的含義分為時間、地點、原因、目的、結果、方式、讓步、條件、比較(也叫程度)等九種。狀語從句連詞有：
① 時間(time): after, as,as soon as, before, every(each) time, hardly(scarcely)…when,immediately, no sooner…than, once, since, the day, the minute, the moment, the second,till, until, when, whenever等。
② 地點(place):everywhere, where, wherever等。
③條件(condition): as/so long as, if, if only, in case, on condition that,only if, providing/provided that, suppose/supposing that, unless等。
④原因(cause): as, because, considering that, in that, in view of the factthat(鑒於), now that, seeing that, since等。
⑤讓步(concession): though, although, as, despite the fact that, evenif(though), for all that, granting/granted, however, in spite of the fact that,no matter + wh-, whatever, wherever, whether…or, while, whoever等。
⑥比較/程度(compare/degree): as…as, not so…as, not the same as, than等。
⑦方式(manner): as, as if(though), the way等。
⑧目的(purpose): for fear that, in order that, in case, lest, so that,that等。
⑨結果(result): but that, so that, so…that, such…that等。

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

1）when,whenever,while,as,after,before,since,till,until,once等。

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.

Ⅶ 英語語法英語從句

主要是賓語從句和狀語從句，如果說考的稍微難一些的話就是定語從句以及名詞性從句，一般考的話後兩者的難度不會很大。
賓語從句在句中作及物動詞或介詞的賓語，從句放在主句之後，前後不用逗號分開。

賓語從句：
引導賓語從句的詞有：

連詞that(在口語中that常可省略)，if, whether,如：

He knows that Jim will work hard.

連接代詞who, whom, which等，如：

Do you know who (whom) they are waiting for?

連接副詞when, where, how, why等，如：Could you tell me how we can get to the station?

3.whether和if都有「是否」的意思，一般情況下兩者可以換用，但在介詞之後，

不定式之前，與or not連用，在句首或在引導表語從句，同位語從句時，只能用whether,如：I want to know if/whether the news is true. He doesn't know whether to stay or not?

4.賓語從句要用陳述句語序。

5.賓語從句一定要注意時態呼應，即：當主句謂語動詞是過去式時，從句中謂語動

詞也要用過去范疇的時態，但若從句陳述的是真理或客觀規律，其謂語的時態仍用一般現在時，如：

He asked who could answer the question.

My father told me that the earth goes around the sun.

6.一個賓語從句只能用一個連詞。

7.當主句謂語動詞是think, believe等動詞時，賓語從句的否定意義要放到主句中。另外，當主句主語為第一人稱時，後面若接附加疑問句，那麼附加疑問句的主語、謂語應與從句中的主謂語保持一致。如：

I don't think he looks like his father, does he?

8.直接引語和間接引語也是賓語從句，直接引語是引述別人的原話，放在引號內，

不用連詞聯接；間接引語是用自己的話轉述別人的話，通常用連接詞與主句聯接。

(1)陳述句變為以that引導的賓語從句，如：

He said,「I'm happy.」[FY()[FY]]He said that he was happy.

(2)一般疑問句變為if(whether)引導的賓語從句，如：

He asked me,「Does his father know Mr Green?」

---He asked me if his father knew Mr Green.

(3)特殊疑問句變為由who, what, where, how等疑問詞(連接代詞或連接副詞)引導的賓語從句，如：

He asked me,「Where is Mr Wang?」

---He asked me where Mr Wang was.

注意上述例句中連詞、時態、語序等變化

Ⅷ 英語的各種從句的語法問題、、、

最常見的就是：賓語從句；還有就是：狀語從句、定語從句；高中的話，還有：同內位語從句、容主語從句、表語從句。
其實，判斷是哪種從句就是看它在句子中作什麼成分，就叫什麼從句。
賓語從句 注意其 語序！！ 用陳述語序；即：主語+can/will/should...+謂語+賓語。
狀語從句主要有條件狀語從句和時間狀語從句等，遵循「主將從現」原則，即主句用將來時，從句用一般現在時代替將來時。
定語從句：首先判斷先行詞，再判斷用哪個引導詞；
同位語從句就是看從句是不是對從句前的名詞的解釋說明，是的話就叫同位語從句；
表語從句就是作句子的表語；
主語從句顧名思義，作句子的主語；一般由what來引導。

Ⅸ 英語中各種從句的例子和用法

定語從句概要： （這是有關定語從句的精要介紹，涵蓋了有關定語從句的各個方面，供參考：） 引導定語從句的關聯詞包括關系代詞和關系副詞。關系代詞有that, which, whose, who, whom, as；關系副詞有when, where, why。關系代詞和關系副詞在定語從句中都充當一定的句法成份。關系代詞在從句中充當動詞的賓語時一般可以省略。 關系代詞的選用比較復雜，受下列條件的制約： (1) 要看先行詞是指人還是指物， (2) 要看關系代詞在從句中句法功能， (3) 要看定語從句是限定性的還是非限定性的。 在定語從句中充當的成分 ↓ 用於限定性或非限定性從句 只用於限定性從句 指人 指物 指人或指物 主語 who which that 賓語 whom which that 謂語 whose whose (of which) That 只能用在限定性定語從句中，而who, whom, which, which 既可用於限定性定語從句中，也可用於非限定性定語從句。 I know that he is a man who means what he says. I know that he is a man that means what he says. 【我知道他是一個守信用的人。】 The gentleman whom she met addressed her with courtesy. The gentleman that she met addressed her with courtesy. 【她遇到的那位先生很有禮貌地向她打了招呼。】 The gentleman she met addressed her with courtesy.（在從句中充當動詞賓語的關系代詞，可以省略。） The watch which was lost has been found. The watch that was lost has been found. 【丟了的表找到了。】 Here is the material which you need. (註：現代美語中不允許這樣用) Here is the material that you need. Here is the material you need. 【你要的材料在這兒了。】 You are the only one whose advice he might listen to. 他也就是聽你的話吧。 關系副詞的選用相對來說比較簡單，如果先行詞是表示時間的名詞，如time, day 等，則用when, 如先行詞為表示地點的名詞，如place, house, area 等等，則選用where。如果先行詞為reason 則選用why I will never forget the mountain village where I spent my childhood. I will never forget the mountain village in which I spent my childhood. 我永遠也不會忘記我度過童年的那個小山村。 I don』t know the reason why he did that. I don』t know the reason for which he did that. 【我不知道他為什麼這么做。】 當先行詞是all, something, nothing 等不定代詞時，或者先行詞的前面有first, last, only, few, much, some, any, no 等詞修飾時，或者先行詞的前面有最高級修飾時，一般只用that 而不用which 來引導定語從句： I have explained everything that I can to you. I have explained everything I can to you. 【我已經盡一切可能把事情向你解釋得一清二楚。】 具體詳情請上網路查詢。從句—請點擊此連接就可查詢各種從句的具體解釋 http://ke..com/view/138129.htm
