初中英語定語從句是怎麼回事啊
⑴ 英語定語從句是怎麼回事呀
定語從句（Attributive Clauses）在句中做定語，修飾一個名詞或代詞，被修飾的名詞,片語或代詞即先行詞。定語從句通常出現在先行詞之後，由關系詞（關系代詞或關系副詞）引出。
關系代詞有：who, whom, whose, that, which等。
關系副詞有：when, where, why等。
18.1 關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，並在句中充當主語、賓語、定語等成分。關系代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。
1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想見的人嗎？（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.
他就是我昨天見的那個人。（whom/that在從句中作賓語）
2) Whose 用來指人或物，(只用作定語, 若指物，它還可以同of which互換）, 例如：
They rushed over to help the man whose car had broken down. 那人車壞了，大家都跑過去幫忙。
Please pass me the book whose (of which) cover is green. 請遞給我那本綠皮的書。
3）which, that
它們所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等，例如：
A prosperity which / that had never been seen before appears in the countryside. 農村出現了前所未有的繁榮。（which / that在句中作賓語）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作賓語）
18.2 關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。
1）when, where, why
關系副詞when, where, why的含義相當於"介詞+ which"結構，因此常常和"介詞+ which"結構交替使用，例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的時候。
Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 這就是他拒絕我們幫助他的理由嗎？
2）that代替關系副詞
that可以用於表示時間、地點、方式、理由的名詞後取代when, where, why和"介詞+ which"引導的定語從句，在口語中that常被省略，例如：
His father died the year (that / when / in which) he was born. 他父親在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住過的地方。
18.3 判斷關系代詞與關系副詞
方法一： 用關系代詞，還是關系副詞完全取決於從句中的謂語動詞。及物動詞後面無賓語，就必須要求用關系代詞；而不及物動詞則要求用關系副詞。例如：
This is the mountain village where I stayed last year.
I'll never forget the days when I worked together with you.
判斷改錯（註：先顯示題，再顯示答案，橫線；用不同的顏色表示 出。）
（錯） This is the mountain village where I visited last year.
（錯） I will never forget the days when I spent in the countryside.
（對） This is the mountain village (which) I visited last year.
（對） I'll never forget the days (which) I spent in the countryside.
習慣上總把表地點或時間的名詞與關系副詞 where, when聯系在一起。此兩題錯在關系詞的誤用上。
方法二： 准確判斷先行詞在定語從句中的成分(主、謂、賓、定、狀)，也能正確選擇出關系代詞/關系副詞。
例1. Is this museum ___ you visited a few days age?
A. where B. that C. on which D. the one
例2. Is this the museum ____ the exhibition was held.
A. where B. that C. on which D. the one
答案：例1 D，例2 A
例1變為肯定句： This museum is ___ you visited a few days ago.
例2變為肯定句： This is the museum ___ the exhibition was held.
在句1中，所缺部分為賓語，而where, that, on which都不能起到賓語的作用，只有the one既做了主句的表語，又可做從句的賓語，可以省略關系代詞，所以應選D。
而句2中, 主、謂、賓俱全，從句部分為句子的狀語表地點，既可用副詞where，又因 in the museum片語，可用介詞in + which 引導地點狀語。而此題中，介詞on 用的不對，所以選A。
關系詞的選擇依據在從句中所做的成分，先行詞在從句中做主、定、賓語時，選擇關系代詞 (who, whom, that, which, whose)； 先行詞在從句中做狀語時，應選擇關系副詞 ( where 地點狀語，when 時間狀語，why 原因狀語) 。
18.4 限制性和非限制性定語從句
1) 定語從句有限制性和非限制性兩種。限制性定語從句是先行詞不可缺少的部分，去掉它主句意思往往不明確；非限制性定語從句是先行詞的附加說明，去掉了也不會影響主句的意思，它與主句之間通常用逗號分開，例如：
This is the house which we bought last month. 這是我們上個月買的那幢房子。（限制性）
The house, which we bought last month, is very nice.這幢房子很漂亮，是我們上個月買的。（非限制性）
2) 當先行詞是專有名詞或物主代詞和指示代詞所修飾時，其後的定語從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，他曾經是我的老師。
My house, which I bought last year, has got a lovely garden. 我去年買的的那幢房子帶著個漂亮的花園。
This novel, which I have read three times, is very touching. 這本小說很動人，我已經讀了三遍。
3) 非限制性定語從句還能將整個主句作為先行詞, 對其進行修飾, 這時從句謂語動詞要用第三人稱單數，例如：
He seems not to have grasped what I meant, which greatly upsets me. 他似乎沒抓住我的意思，這使我心煩。
Liquid water changes to vapor, which is called evaporation. 液態水變為蒸汽，這就叫做蒸發。
說明：關系代詞that和關系副詞why不能引導非限制性定語從句。
18.5 介詞+關系詞 P>
1）介詞後面的關系詞不能省略。
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 和where 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?
18.6 as, which 非限定性定語從句
由as, which 引導的非限定性定語從句，as和which可代整個主句，相當於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.
典型例題
1）Alice received an invitation from her boss, ___came as a surprise.
A. it B. that C. which D. he
答案C. 此為非限定性從句，不能用 that修飾，而用which.，it 和he 都使後句成為句子，兩個獨立的句子不能單以逗號連接。況且選he句意不通。
2）The weather turned out to be very good, ___ was more than we could expect.
A. what B. which C. that D. it
答案B。which可代替句子，用於非限定性定語從句，而what不可。That 不能用於非限定性定語從句，it不為連詞，使由逗號連接的兩個句子並在一起在英語語法上行不通。
3）It rained hard yesterday, ____ prevented me from going to the park..
A. that B. which C. as D. it
答案B.
as 和which在引導非限制性定語從句時，這兩個關系代詞都指主句所表達的整個意思，且在定語從句中都可以作主語和賓語。但不同之處主要有兩點：
(1） as 引導的定語從句可置於句首，而which不可。
(2） as 代表前面的整個主句並在從句中作主語時，從句中的謂語必須是系動詞；若為行為動詞，則從句中的關系代詞只能用which.。
在本題中，prevent由於是行為動詞，所以正確選項應為B。
As 的用法
例1. the same… as；such…as 中的as 是一種固定結構, 和……一樣……。
I have got into the same trouble as he (has).
例2. as可引導非限制性從句，常帶有'正如'。
As we know, smoking is harmful to one's health.
As is known, smoking is harmful to one's health.
As是關系代詞。例1中的as作know的賓語；例2中，它充當從句的主語，謂語動詞know要用被動式。
18.7 先行詞和關系詞二合一
1)Whoever spits in public will be punished here.
(Whoever 可以用 anyone who 代替)
2)The parents will use what they have to send their son to technical school.
(what 可以用all that代替)
18.8 what/whatever;that/what; who/whoever
1）what = the thing which；whatever = anything
What you want has been sent here.
Whatever you want makes no difference to me.
2) who= the person that whoever= anyone who
（錯）Who breaks the law will be punished.
（錯）Whoever robbed the bank is not clear.
（對）Whoever breaks the law will be punished.
（對）Who robbed the bank is not clear.
3) that 和 what
當that引導定語從句時 ，通常用作關系代詞，而引導名詞性從句時，是個不充當任何成分的連接詞。賓語從句和表語從句中的that常可省略。What只能引導名詞性從 句， 用作連接代詞，作從句的具體成分，且不能省略。
I think (that) you will like the stamps.
What we need is more practice.
18.9 關系代詞that 的用法
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, much, few, any, little等作先行詞時，只用that，不用which。
c) 先行詞有the only, the very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。.
e) 先行詞既有人，又有物時。
舉例：
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。
⑵ 初中英語定語從句
不用啊。定語從句，你有先行詞了啊，先行詞在從句中充當成分
⑶ 初中英語定語從句講解
定語從句即用句子來做定語，被修飾或被限制的詞稱作先行詞，例如
1.I don't know the girl who is talking there.
2.I don't know the girl who you met just now.
3.Give me the book that you read just now.
4.Give me the book ,which you read just now.
5.Give me the pen that you write with.
6.Give me the pen with which you write .
仔細看句子專中的book 和pen就是先行詞，他們後面屬的who that which 就是引導定語從句的關系代詞，當先行詞是人用who,先行詞是物用that,先行詞後出現介詞或逗號用which.
這是一種捷徑，細節問題找本語法書慢慢學。
⑷ 英語的定語從句是怎麼回事，好心人告訴下
定語概述
定語是用來修飾、限定、說明名詞或代詞的品質與特徵的。 主要有形容詞此外還有名詞、代詞、數詞、介詞短語、動詞不定式（短語）、分詞、定語從句或相當於形容詞的詞、短語或句子都可以作定語。 漢語中常用『……的』表示。定語和中心語之間是修飾和被修飾、限制和被限制的關系。在漢語中，中心語與定語二者之間有的需要用結構助詞「的」，有的不需要，有的可要可不要。 「的」是定語的標志。
[編輯本段]英語中的定語
The little boy needs a blue pen.(little修飾名詞boy；blue修飾名詞pen.）/小男孩需要一支藍色的鋼筆。
Tom is a handsome boy./Tom是個英俊的男孩。
There is a good boy./有個乖男孩。
數詞作定語相當於形容詞：Two boys need two pens./兩個男孩需要兩支鋼筆。
The two boys are students./這兩個男孩是學生。
There are two boys in the room./房間里有兩個男孩。
代詞或名詞所有格作定語：
His boy needs Tom's pen./他的男孩需要Tom的鋼筆。
His name is Tom./他的名字是湯姆。
There are two boys of Tom's there./那兒有Tom家的兩個男孩。
介詞短語作定語：
The boy in the classroom needs a pen of yours./教室里的男孩需要你的一支鋼筆。
The boy in blue is Tom./穿藍色衣服的孩子是湯姆。
There are two boys of 9,and three of 10./有兩個9歲的，三個10歲的男孩。
名詞作定語：
The boy needs a ball pen./男孩需要一支圓珠筆。
It is a ball pen./這是一支圓珠筆。
There is only one ball pen in the pencil box./這鉛筆盒裡只有一支圓珠筆。
副詞作定語：
The boy there needs a pen./那兒的男孩需要一支鋼筆。
The best boy here is Tom./這里最棒的男孩是Tom。
不定式作定語：
The boy to write this letter needs a pen./寫這封信的男孩需要一支鋼筆。
The boy to write this letter is Tom./將要寫這封信的男孩是湯姆。
There is nothing to do today./今天沒有事要做。
分詞（短語）作定語：
The smiling boy needs a pen bought by his mother./那個微笑的男孩需要一支他媽媽買的鋼筆。
The pen bought by her is made in China./她買的筆是中國產的。
There are five boys left./有五個留下的男孩。
定語從句：

The boy you will know is Tom./你將認識的男孩叫湯姆。
There are five boys who will play the game./參加游戲的男孩有五個。
定語的位置一般有兩種：用在所修飾詞之前的叫前置定語，用在所修飾詞之後的叫後置定語。
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。
1）定語前置
在英語里,一般定語前置時的次序為:限定詞，形容詞、分詞、動名詞和名詞性定語。但當幾個形容詞同時出現在名詞短語之前,我們要注意其次序。其形容詞遵循的詞序為：限觀形齡色國材，指：限定詞（一般指數量）；外觀（美麗等）；形狀（大小，高矮，肥瘦）；年齡；顏色；國籍；材料；用途。如：
1限定詞 2 外觀 3形狀 4年齡 5顏色 6國籍 7材料 8用途
A famous American university.
An interesting little red French oil painting.
A new plastic bucket.
A purple velvet curtains
An elegant German clock
另外,有些形容詞也有特殊的次序:
(1) 描述身體特徵的形容詞先於表示情感和性格特徵的形容詞
例如:a small lovely girl , a long patient queue , a pale anxious patient ;
(2) 表示顏色的形容詞放在表示情感和性格特徵的形容詞之後
例如:a kindly black teacher ,an inquisitive brown dog ;
(3) little ,old 和young 有時可以作為名詞短語不可分割的一部分,所以可以直接放在名詞之前,
例如:a lovely little girl
(4) 表示性格特徵的形容詞可以放在old young 之前,也可放在old young 之後,例如:
a young ambitious man (強調年齡) ,an ambitious young man(強調雄心勃勃) 。
當然,三個以上形容詞連用作定語,就顯得累贅,因此上面所說的情況一般較少出現.
2）定語後置
(1）短語作定語一般後置
It was a conference fruitful of results. 那是一個碩果累累的會議。
He gave me a basket full of eggs. 他給我一個裝滿雞蛋的籃子。
English is a language easy to learn but difficult to master. 英語是一門容易學但是難精通的語言。
The boys hardest to teach are all in his class.最難教的男生都在他的班裡了。
（2）修飾some，any，no，every等詞構成的不定代詞的定語都後置
Let』s go somewhere quiet. 咱們去找個安靜一點的地方吧。
There is nothing important in today's newspaper. 今天報紙上沒有什麼重要的東西。
Do you have anything more to say? 你還有什麼話要說嗎?
（3）副詞作定語
The people here are very friendly. 這里的人很友好。
They lived in the room above.他們住在樓上的房間。
（4）動詞、名詞轉化而來的以-able,-ible 結尾的形容詞作定語
He is a person dependable. 他是一個可以依靠的人
This is the only transportation means available. 這是唯一可行的交通工具。
（5）起強調用的單個分詞
Everybody involved should stay here.
The college mentioned.
（6）特殊詞
Could you tell me something imporpant.
3) 定語從句
英語里有大量的定語從句,而漢語里卻沒有定語從句的說法。英語中定語從句中甚至還可能包含定語從句,即多重定語從句。如： A healthy diet includes enough but not too many kinds of foods that provide the body with the nutrients that it needs to function properly. (健康的飲食包括的食物應該充足但又不過多。這些食物提供身體正常活動所必需的營養)
(1）英語的復合句中,分句以其主句為基幹,通過連接手段,一層一層地展開,就好像一棵樹的樹幹上長出大枝子,大枝子上再長出小枝子。漢語的分句則更多按照時間發生的順序出現,依次展開。
如： 「偉大領袖和導師毛主席領導中國共產黨進行了艱苦卓絕的斗爭,建立了新中國,人民得到了解放,科學得到了解放。」這句話,譯成英語便成了With the founding of new China (which was) born of arous struggles (which were) waged by the Chinese Communist Party (which was) under the leadership of our great leader and teacher Chairman Mao , our people , and science as well , won emancipation.（王良蘭，2003）
(2）英語中的非限制性定語從句所表達的信息,在漢語里一般由另一個小句來表達。用非限制性定語從句時，前應加逗號，並且非限制性定語從句引導詞只能用which，不能用that。
例如:She asked for his help which he gladly gave. 她要求他幫忙,他愉快地幫助了她。
再如: It was a century ring which the country suffered continuously from wars.
一個世紀過去了,在這期間這個國家不斷遭受戰亂之苦。
⑸ 初中英語：定語從句的用法
1.what不能引導定語從句.
2.關系詞的分析須考慮它在定語從句中的成分。
一.指人的關系代詞有who、whose、whom、that. 試分析：
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. （=The man who/whom that my father shook hands with just now is our headmaster.）註：
A．指人時有時只用who不宜用that。
1．先行詞為one、ones或anyone
（1）The comrade I want to learn from is the one who studies hard and works hard.
（2）Anyone who breaks the law should be punished.
2．先行詞為these時
These who are going to Beijing are the best students of our school.
3．在there be 開頭的句子中
There is a student who wants to see you.
4．一個句子中帶有兩個定語從句，其中一個定語從句的關系代詞是that，另一個宜用who，以免重復。
The student that won the first prize is the monitor who works hards.
5．在非限制性定語從句中
A。I met a friend of mine in the street, who had just come from Japan.
B．主句以who開頭的句子中,只用that,不用who。
二．指物的關系代詞有which、whose(=of which)、that. 試分析：
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
註：
A. 介詞如果位於作為其賓語的關系代詞之前時，只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短語動詞中的介詞不可與動詞拆開，在定語從句中其介詞不可前置，只能放在其動詞之後。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping』s son.
C．指物時，下列情況下只能用that ，不宜用which。
（1）先行詞為不定代詞，如All、much、anything、everything、nothing、something、none、the one等。
We are willing to do anything that is good to the people.
I have told them all (that) I know.
All that can be done has been done.
（2）先行詞是序數詞或被序數詞、修飾時。
The first book that I read last night was an English novel.
（3）先行詞是形容詞最高級或被最高級修飾時。
This is one of the most interesting films that I have ever seen.
This is the best that can be done now.
（4）如果有兩個或兩個以上分別表示人和物的先行詞時(先行詞既有人又有物)，定語從句的關系代詞用which和who都不合適，只能用that。
We know nothing about the doctors and the hospitals that you are talking about.
There are sheep and men that can be seen on the hill.
（5）如果先行詞被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修飾時。
This is the only book that can be lent to you.
（6）當主句是以which開頭的特殊問句時，關系代詞只用that。
Which is the dictionary that he used yesterday ?
D．只物時，下列情況下只能用which，不宜用that。
（1）關系代詞放在介詞之後
This is the factory in which we once worked.
（2）非限制性定語從句中
This is the book, which is written by Lu Xun.
（3）that，Those作主語時
Those which are on the desk are English books.
E．先行詞前有such、the same、 as時, 關系代詞用as，不用that, 但the same…as…表示同樣的, the same…that…表示同一的
He knows as many people as are present at the meeting.
Such people as you refer to are rare nowadays.
三．比較When/which、where /which、why.
which I still never forget.
This is the day when I joined the party.
which he spent reading the books.
where I found the book.
which makes machines.
This is the place which we once visited.
which I will never forget.
which I am looking for.
限制性定語從句與非限制性定語從句的區別：
限制性定語從句
非限制性定語從句
All the students who study hard have passed.學習努力的學生都考試及格了。(只有努力的及格了，不努力的沒及格。) All the students ,who study hard have passed.所有的學生都及格了，他們學習努力。（沒有人不及格，這些學生都很努力。）
從句是先行詞不可缺少的定語（如去掉，主句意思就不完整或不正確。）從句是對先行詞的附加說明（如去掉，主句意思仍清楚，不受影響。）與主句關系密切，不用逗號與主句關系不十分密切，用逗號與主句隔開譯為漢語時，從句譯在先行詞前，與先行詞用「的」連接譯為漢語時，從句放在主句後面關系代詞that可以代替who、whom(指人)、which(指物) 關系代詞不用that,只用who、whom(指人)、which(指物) 關系代詞代替賓語時可以省略關系代詞不能省略關系代詞as和which
先研究下面兩個例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出來，這頭象像條蛇。
○2.Tom didn』t pass the physics exam, which made his parents very angry. Tom物理考試不及格，這使得他父親很生氣。
這兩個例句中，as和which所代表的都是整個主句所表示的內容。但有兩點不同之處：
1．在形式上as引導的非限制性定語從句可位於主句的後面，也可位於主句的前面；而which引導的非限制性定語從句只能位於主句的後面，不能位於主句的前面。
2．在意義上，as引導的定語從句和主句的關系一般為一致關系，常譯為「正如……」，「就像……」，而which引導的定語從句和主句的關系是因果關系，或which引導的定語從句是對主句的評論。因此，在意思通順的情況下，which可代替as，而as許多時候不能代替which，如句○2。再如：
1．He was late again, as / which we had expected. =As we had expected, he was late again. 正如我們所料，他又遲到了。/他又遲到了這是我們早就料到的。
2． The street hasn』t been cleared for weeks, which makes it very dirty. 街道好多星期沒有打掃了，因此整條街很臟。（不用as）
3．The young man cheated his friend of much money, which was disgraceful. 那年輕人詐騙了他朋友許多錢財，這是不光彩的。（不用as）
4．He takes exercise everyday, which has done a lot of good to his health. 他每天運動，這對他的身體很有好處。（不用as）
5．As has already been pointed out, English is rather difficult for a foreigner. 正如已經指出的那樣，英語對於初學者說，是相當難學的。在such…as…、the same…as…、 as…、 as many…/much as…等結構中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 這樣的書對於初學的人來說是太難了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大樓里。
3.He knows as many people as are present at the meeting. 他認識所有到會的人。
4.That day we all got up early as usual. 那天我們和平時一樣，都起得很早。
「One of the +復數名詞」後面定語從句中謂語單復數情況
這一結構後面的定語從句的謂語動詞通常用復數形式，跟定語從句所靠近的那個復數名詞在數上保持一致。如：
1． That is one of the books that are required for study at school.
2． This is one of the most wonderful novels that have been published since 1990.
3． She is one of the few persons who know Spanish .
4． This is one of the most famous plays that were written in the thirties,
如果one of +復數名詞這一結構前面帶有the only、the very之類的限定語，後面定語從句的謂語動詞則要用單數形式，這是因為定語從句在意義上修飾的是而不是那個復數名詞。如：
1.He is the only one of the teachers who knows French in our school.( 修飾the only one)
He is one of the teachers who know French in our school.( 修飾the teachers)
2.This is the only one of the rooms that is free now. (修飾the only one)
This is one of the rooms that are free now. (修飾rooms)
as與which引導的定語從句
兩者均可引導非限制性定語從句，有時可以互換，但下列情況多用as。
1. 關系代詞引導的定語從句居句首時。 As we all know, the earth is round.
2. 當與such或the same連用時，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 當從句和主句語義一致時，用as，反之則用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在從句中作主語時，後面常接行為動詞的被動語態，如be known，be said，be reported等，如從句中行為動詞是主動語態，一般要用which作主語。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
⑹ 初中英語定語從句問題
這句話有兩種說法
一是 All that 這是定語從句 先行詞是all 如果只有that 那就沒有先行詞了 當然也回不對答了
二是 What 這句話就是賓語從句 和in是介賓結構 What是賓語從句里做賓語
若有疑問 歡迎來問我 望採納
⑺ 初中英語定語從句的用法
1.what不能引導定語從句.
2.關系詞的分析須考慮它在定語從句中的成分。
一.指人的關系代詞有who、whose、whom、that. 試分析：
The old man who/whom /that we visited yesterday is a famous artist.
Miss Wang is taking care of the child whose parents have gone to Beijing .
The man with whom my father shook hands just now is our headmaster. （=The man who/whom that my father shook hands with just now is our headmaster.）註：
A．指人時有時只用who不宜用that。
1．先行詞為one、ones或anyone
（1）The comrade I want to learn from is the one who studies hard and works hard.
（2）Anyone who breaks the law should be punished.
2．先行詞為these時
These who are going to Beijing are the best students of our school.
3．在there be 開頭的句子中
There is a student who wants to see you.
4．一個句子中帶有兩個定語從句，其中一個定語從句的關系代詞是that，另一個宜用who，以免重復。
The student that won the first prize is the monitor who works hards.
5．在非限制性定語從句中
A。I met a friend of mine in the street, who had just come from Japan.
B．主句以who開頭的句子中,只用that,不用who。
二．指物的關系代詞有which、whose(=of which)、that. 試分析：
1. I like the books which / that were written by Lu Xun.
2. The desks (which/that) we made last year were very good.
3. This is the house in which we lived last year. (= This is the house which /that we lived in last year.)
4. I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)
註：
A. 介詞如果位於作為其賓語的關系代詞之前時，只能用whom、 which不能用who或that.
(1). The girl about whom they were talking is our monitor.
(2). The book in which there are many interesting things was written by Li Ming.
B. 部分短語動詞中的介詞不可與動詞拆開，在定語從句中其介詞不可前置，只能放在其動詞之後。
Is this the book which she is looking for?
The old man who/whom they are waiting for is Professor Li.
The child who/whom she is looking after is Wang Ping』s son.
C．指物時，下列情況下只能用that ，不宜用which。
（1）先行詞為不定代詞，如All、much、anything、everything、nothing、something、none、the one等。
We are willing to do anything that is good to the people.
I have told them all (that) I know.
All that can be done has been done.
（2）先行詞是序數詞或被序數詞、修飾時。
The first book that I read last night was an English novel.
（3）先行詞是形容詞最高級或被最高級修飾時。
This is one of the most interesting films that I have ever seen.
This is the best that can be done now.
（4）如果有兩個或兩個以上分別表示人和物的先行詞時(先行詞既有人又有物)，定語從句的關系代詞用which和who都不合適，只能用that。
We know nothing about the doctors and the hospitals that you are talking about.
There are sheep and men that can be seen on the hill.
（5）如果先行詞被the only、the very、the last、the same、any、 few 、little、no、 all 、one of、 just修飾時。
This is the only book that can be lent to you.
（6）當主句是以which開頭的特殊問句時，關系代詞只用that。
Which is the dictionary that he used yesterday ?
D．只物時，下列情況下只能用which，不宜用that。
（1）關系代詞放在介詞之後
This is the factory in which we once worked.
（2）非限制性定語從句中
This is the book, which is written by Lu Xun.
（3）that，Those作主語時
Those which are on the desk are English books.
E．先行詞前有such、the same、 as時, 關系代詞用as，不用that, 但the same…as…表示同樣的, the same…that…表示同一的
He knows as many people as are present at the meeting.
Such people as you refer to are rare nowadays.
三．比較When/which、where /which、why.
which I still never forget.
This is the day when I joined the party.
which he spent reading the books.
where I found the book.
which makes machines.
This is the place which we once visited.
which I will never forget.
which I am looking for.
限制性定語從句與非限制性定語從句的區別：
限制性定語從句
非限制性定語從句
All the students who study hard have passed.學習努力的學生都考試及格了。(只有努力的及格了，不努力的沒及格。) All the students ,who study hard have passed.所有的學生都及格了，他們學習努力。（沒有人不及格，這些學生都很努力。）
從句是先行詞不可缺少的定語（如去掉，主句意思就不完整或不正確。）從句是對先行詞的附加說明（如去掉，主句意思仍清楚，不受影響。）與主句關系密切，不用逗號與主句關系不十分密切，用逗號與主句隔開譯為漢語時，從句譯在先行詞前，與先行詞用「的」連接譯為漢語時，從句放在主句後面關系代詞that可以代替who、whom(指人)、which(指物) 關系代詞不用that,只用who、whom(指人)、which(指物) 關系代詞代替賓語時可以省略關系代詞不能省略關系代詞as和which
先研究下面兩個例句：
○1.This elephant is like a snake, as /which everybody can see. =As everybody can see, this elephant is like a snake. 任何人都看得出來，這頭象像條蛇。
○2.Tom didn』t pass the physics exam, which made his parents very angry. Tom物理考試不及格，這使得他父親很生氣。
這兩個例句中，as和which所代表的都是整個主句所表示的內容。但有兩點不同之處：
1．在形式上as引導的非限制性定語從句可位於主句的後面，也可位於主句的前面；而which引導的非限制性定語從句只能位於主句的後面，不能位於主句的前面。
2．在意義上，as引導的定語從句和主句的關系一般為一致關系，常譯為「正如……」，「就像……」，而which引導的定語從句和主句的關系是因果關系，或which引導的定語從句是對主句的評論。因此，在意思通順的情況下，which可代替as，而as許多時候不能代替which，如句○2。再如：
1．He was late again, as / which we had expected. =As we had expected, he was late again. 正如我們所料，他又遲到了。/他又遲到了這是我們早就料到的。
2． The street hasn』t been cleared for weeks, which makes it very dirty. 街道好多星期沒有打掃了，因此整條街很臟。（不用as）
3．The young man cheated his friend of much money, which was disgraceful. 那年輕人詐騙了他朋友許多錢財，這是不光彩的。（不用as）
4．He takes exercise everyday, which has done a lot of good to his health. 他每天運動，這對他的身體很有好處。（不用as）
5．As has already been pointed out, English is rather difficult for a foreigner. 正如已經指出的那樣，英語對於初學者說，是相當難學的。在such…as…、the same…as…、 as…、 as many…/much as…等結構中,as不能用which代替。如：
1.Such books as this are too difficult for beginners. 這樣的書對於初學的人來說是太難了。
=Books such as this are …
=Books like this are …
2.I live in the same building as he (does). 我和他住再同一座大樓里。
3.He knows as many people as are present at the meeting. 他認識所有到會的人。
4.That day we all got up early as usual. 那天我們和平時一樣，都起得很早。
「One of the +復數名詞」後面定語從句中謂語單復數情況
這一結構後面的定語從句的謂語動詞通常用復數形式，跟定語從句所靠近的那個復數名詞在數上保持一致。如：
1． That is one of the books that are required for study at school.
2． This is one of the most wonderful novels that have been published since 1990.
3． She is one of the few persons who know Spanish .
4． This is one of the most famous plays that were written in the thirties,
如果one of +復數名詞這一結構前面帶有the only、the very之類的限定語，後面定語從句的謂語動詞則要用單數形式，這是因為定語從句在意義上修飾的是而不是那個復數名詞。如：
1.He is the only one of the teachers who knows French in our school.( 修飾the only one)
He is one of the teachers who know French in our school.( 修飾the teachers)
2.This is the only one of the rooms that is free now. (修飾the only one)
This is one of the rooms that are free now. (修飾rooms)
as與which引導的定語從句
兩者均可引導非限制性定語從句，有時可以互換，但下列情況多用as。
1. 關系代詞引導的定語從句居句首時。 As we all know, the earth is round.
2. 當與such或the same連用時，一般用as。 Such books as you tell me are interesting. I have the same plan as you.
3. 當從句和主句語義一致時，用as，反之則用which。 She has married again, as was expected. She has married again, which was unexpected.
4. as在從句中作主語時，後面常接行為動詞的被動語態，如be known，be said，be reported等，如從句中行為動詞是主動語態，一般要用which作主語。
She has been late again, as was expected.
Tom has made great progress, which made us happy.
⑻ 英語的定語從句是怎麼回事的呀!!!
定語從句（Attributive Clauses）在句中做定語，修飾一個名詞或代詞，被修飾的名詞,片語或代詞即先行詞。定語從句通常出現在先行詞之後，由關系詞（關系代詞或關系副詞）引出。
關系代詞有：who, whom, whose, that, which等。
關系副詞有：when, where, why等。 18.1 關系代詞引導的定語從句
關系代詞所代替的先行詞是人或物的名詞或代詞，並在句中充當主語、賓語、定語等成分。關系
代詞在定語從句中作主語時，從句謂語動詞的人稱和數要和先行詞保持一致。
1）who, whom, that
這些詞代替的先行詞是人的名詞或代詞，在從句中所起作用如下：
Is he the man who/that wants to see you?
他就是你想見的人嗎？（who/that在從句中作主語）
He is the man whom/ that I saw yesterday.
他就是我昨天見的那個人。（whom/that在從句中作賓語）
2) Whose 用來指人或物，(只用作定語, 若指物，它還可以同of which互換）, 例如：
They rushed over to help the man whose car had broken down. 那人車壞了，大家都跑過去幫忙。
Please pass me the book whose (of which) cover is green. 請遞給我那本綠皮的書
3）which, that 它們所代替的先行詞是事物的名詞或代詞，在從句中可作主語、賓語等，例如：
A prosperity which / that had never been seen before appears in the countryside. 農村出現了前所未有的繁榮。（which / that在句中作賓語）
The package (which / that) you are carrying is about to come unwrapped. 你拿的包快散了。(which / that在句中作賓語 18.2 關系副詞引導的定語從句
關系副詞可代替的先行詞是時間、地點或理由的名詞，在從句中作狀語。
1）when, where, why
關系副詞when, where, why的含義相當於"介詞+ which"結構，因此常常和"介詞+ which"結構交替使用，例如：
There are occasions when (on which) one must yield. 任何人都有不得不屈服的時候。
Beijing is the place where (in which) I was born. 北京是我的出生地。
Is this the reason why (for which) he refused our offer? 這就是他拒絕我們幫助他的理由嗎？
2）that代替關系副詞
that可以用於表示時間、地點、方式、理由的名詞後取代when, where, why和"介詞+ which"引導的定語從句，在口語中that常被省略，例如：
His father died the year (that / when / in which) he was born. 他父親在他出生那年逝世了。
He is unlikely to find the place (that / where / in which) he lived forty years ago. 他不大可能找到他四十年前居住過的地方。
用關系代詞，還是關系副詞完全取決於從句中的謂語動詞。及物動詞後面無賓語，就必須要求用關系代詞；而不及物動詞則要求用關系副詞。例如：
This is the mountain village where I stayed last year.
I"ll never forget the days when I worked together with you.
判斷改錯（註：先顯示題，再顯示答案，橫線；用不同的顏色表示出。）
（錯） This is the mountain village where I visited last year.
（錯） I will never forget the days when I spent in the countryside.
（對） This is the mountain village (which) I visited last year.
（對） I"ll never forget the days (which) I spent in the countryside.
習慣上總把表地點或時間的名詞與關系副詞 where, when聯系在一起。此兩題錯在關系詞的誤用上。
