2013屆高三英語語法要點精講（配最新高考+模擬）
專題01 定語從句
【考綱解讀】
定語從句在歷年的高考全國卷及各地卷的單項填空中，都是考試熱點。在今后的高考試題中，定語從句仍是考查的重點。
定語從句常被考查的知識有：（1）九個不同的關系代詞或副詞引導的限制性定語從句；（2）七個不同的關系代詞或副詞引導的非限制性定語從句；（3）對as，which，that，what代詞的理解區分及運用。考查往往是通過關系代詞或關系副詞實現，并考查定語從句、狀語從句、名詞性從句的區別。總之，對定語從句的考查主要集中在關系代詞和關系副詞的選擇上，我們尤其要注意“介詞+關系代詞”引導的定語從句。
【知識要點】
一、定語從句的意義?
形容詞性從句一般稱為定語從句，在句子中起定語作用，修飾一個名詞或代詞，有時可修飾一個句子。被定語從句修飾的詞叫先行詞。?
定語從句的位置：一般置于先行詞之后，由關系代詞和關系副詞引導。??
二、關系詞的用法?
引導定語從句的關系代詞有which，that，who，whom，whose。?
關系副詞有when，where，why等。?
關系代詞和關系副詞不僅有連接先行詞和從句的作用，而且在從句中擔當一個句子成分。
1.關系代詞的用法：?
1)由who引導的定語從句?
關系代詞who只能指人，在從句中作主語或賓語。如：?
A teacher is a person who passes knowledge to the student.?
教師是傳授知識的人。（關系代詞在從句中作主語）?
The man who can do this work will get 1000 dollars.?
能夠做此工作的人將獲得1000美元。（關系代詞who在從句中作主語）?
2)由whom引導的定語從句?
關系代詞whom只能指人，是who的賓格，在從句中作賓語，在口語中常常省略。如：?
The man whom you met on the street is my father.?
你在街上碰到的那個人是我父親。（關系代詞who在從句中作賓語，可以省略）?
The woman (whom)you talked with yesterday will come here the day after tomorro?
昨天和你談話的那位婦女后天這兒。（關系代詞whom在從句中作賓語，可以?省略）??
3)由that引導的定語從句?
關系代詞that在從句中既可以作主語，又可作賓語；既可指人，又可指物。如：?
She is the woman that often comes here.?
她就是常常這兒的那個婦女。（關系代詞that在從句中作主語，指人）?
The book that is on the desk was written by my grandfather.?
桌子上的那本書是我祖父寫的。（關系代詞that在從句中作主語，指物。此句中的that可以用which替換）?
Is there anything that I can do for you? 我能為你做點什么呢？（關系代詞that在從句中作賓語，指物。此句中的that不能用which替換）?
The passenger and the suitcases that were still waiting had to be transferred to another plane. 仍在等待的乘客和行李只得改乘另一架飛機。(這句的關系代詞that不能用which替換，因為它在此句中既指人又指物)?
4)由which引導的定語從句?
關系代詞which一般指物，在從句中可作主語，也可以作賓語。如：?
He came late，which made the teacher angry.?
他晚了，這使老師很生氣。（which引導非限定性定語從句，在從句中作主語）?
That is the pencil which I lost yesterday.?
那就是我昨天丟失的鉛筆。（which引導限定性定語從句，在從句中作賓語，which可以省略）5)由whose引導的定語從句?
關系代詞whose是who的所有格，在從句中作定語，既可指人，又可指物。如：?
This is the boy whose parents died last year. 這是那個父母去年去世的男孩。 （whose作定語，指人）?
注：“whose+名詞中心詞”這一結構在定語從句中既能作主語，又能作賓語。whose 的先行詞常用指人，但有時也可以用指具體事物或抽象概念，這時可以與of which 結構互換，詞序是：“名詞+of which”。如：?
They came to a house whose back wall had broken down.(= the back wall of which)他們到后墻已經倒塌的一個房子。?
He’s written a book the name of which I’ve completely forgotten.(= whose name)他寫了本書，書的名字我徹底忘了。
2.使用關系代詞引導定語從句時應注意的幾點?
1)當先行詞指人時，許多情況下既可以用that也可以用who，但在下列情況下，宜用who而不用that。?
先行詞是one，ones，anyone時，宜用who。如：?
Anyone who breaks the law should be punished.?
任何觸犯法律的人都應該受到?懲罰。??
先行詞為those時，宜用who。如：?
Those who want to see the film sign up here. 想看電影的人在這兒簽名。?
一個句子帶有兩個定語從句時，其中一個定語從句的關系代詞用that，另一個用who。?
The boy that you met at the school gate yesterday morning is our monitor who studies very hard.
昨天早上你在校門口遇到的那個男孩是我們班學習很用功的班長。?
2)當先行詞指物時，許多情況下，既可以用關系代詞which，也可用關系代詞that，但在下列情況中，只能用關系代詞that，而不用which。?
在there+be 的句型中，句子的主語是先行詞，而且又是物。如：?
There are two novels that I want to read.我要讀的有兩本小說。?
There is no work that can be done no 沒有什么工作現在能做的了。?
當先行詞為主句的表語或者關系代詞為從句的表語時。如：?
This is the book that was bought yesterday.這就是昨天買的書。?
Our school is no longer the school that it used to be.我們的學校不再是以前的學校了。
以Here is (are)開頭的句子時。如：?
Here is a film that will move anyone.這是一部將使任何人受感動的電影。?
Here are two books that I will buy.這是我要買的兩本書。?
It is (high)time+定語從句中。如：?
It is time that we should have a rest.我們應該休息了。?
It is high time that they started out.他們該動身了。?
當先行詞是way等詞時，關系代詞用that或者in which在定語從句中作方式狀語時，在口語中，常可省略。如：?
This is the way that my father did this work.這就是我父親做此工作的方式。?
She admired the way in which I answered the questions.她羨慕我回答問題的方式。?
在雙重限定性定語從句中，如果一個從句用who或者which引導時，那么另一個從句用that引導。如：?
He is the student that I have ever see who can jump highest.?
他是我曾經看到過跳的最高的學生。?
y brother studies in the school which is the most beautiful in our city that isn’t far from here.?
我的弟弟在我們的城市最美麗的學校讀書，并且離這兒不遠。?
當先行詞被the last ，the very 和the only修飾時。如：?
This is the very pen that I am looking for.這正是我找的鋼筆。?
The only book I want to read is missing.我惟一想看的書不見了。?
在強調句子中，并且以who，which，what開頭時。如：?
Who was it that was lost ?究竟是誰迷路了？（此句中，最好不用who代替that，避免重復）What was it that you did last week?你上周究竟做什么了？?
當先行詞前有序數詞時。如：?
You are the first person that I want to ask for. 你是我要見的第一個人。?
This is the second book that I have ever written.這是我寫的第二本書。?
當先行詞被all，every，no，some，few，little，much，both等修飾時，如：?
This is all that I want to say at the meeting.這就是我在會上要說的。?
Have you any books that are worth reading? 你有值得看的書嗎？?
當先行詞既指人又指物時。如：?
The professor and his achievement that I heard about are admired by them.?
我聽說的那位教授和他的成就得到他們的贊美。?
Let’s talk about the persons and the things that we can remember.?
讓我們談論能夠想起的人和事。?
當先行詞為anything，everything，nothing時，關系代詞用that,不用which；但用something時，用which或者that均可。如：?
Everything we have seen in China is moving.我們在中國看見的東西感人。?
I have nothing that is worth reading.我沒有什么值得一讀的東西。?
當先行詞是疑問代詞who時。如：?
Who that you have ever seen can beat him in chess? 你曾見過誰能在棋藝上打敗他？?
3)that，which，whom在定語從句中作賓語可以省略。如：?
This is the book (which)you were looking for yesterday. 這就是你昨天找的那本書。?
I don’t like the novel (that)you are reading.我不喜歡你看的這本小說。?
4)定語從句中關系代詞作主語時，從句的人稱、數與先行詞一致。如：?
Those who are in their forties are required to have a physical examination this afternoon.?
請那些年齡在四十幾歲的人于今天下午去進行體檢。?
（先行詞those是復數，關系代詞who也就看作是復數，所以從句的謂語動詞就用了復數形式are了）?
This is the magazine which was sent to me by post.這是通過郵局寄給我的雜志。?
（先行詞the magazine是單數，關系代詞which也就看作是單數，所以從句的謂語動詞就用了單數形式was sent）?
5)定語從句的時態不要求與主句時態一致。如：?
The story which I read last night is very interesting.?
我昨天晚上看的那則故事非常有趣。
3.關系副詞的用法?
1)when 指時間，在從句中作時間狀語，它的先行詞通常有time，day，morning，night，week，year 等。如：?
I still remember the time when I first became a college student.?
我仍然記得我成為大學生的那個時刻。?
Do you know the date when Lincoln was born? 你知道林肯出生的日期嗎？?
注：when時常可以省略，特別是在某些句型和某些時間狀語中。如：?
Each time he came，he did his best to help us.每次他，都盡他所能幫我們。?
2)where指地點，在從句中作地點狀語。它的先行詞通常有place，spot，street，house，room，city，town，country等。如：?
This is the hotel where they are staying.這是他們住的旅館。?
I forget the house where the Smiths lived.我不記得史密斯先生住過的房子了。?
注：where有時也可以省略。如：?
This is the place (where)we met yesterday. 這是我們昨天見面的地方。?
3)why指原因或理由，它的先行詞只有reason。如：?
That is the reason why he is leaving so soon.那就是他為什么要離開的原因。?
注：why時常也可以省略。如：?
That is the real reason he did it.那就是他做此事的真正原因。
4.使用關系副詞應注意下列幾點：?
1)這三個關系副詞在意義上都相當于一定的介詞+which結構：?
when = on (in，at，during...)+which;?
where = in (at，on...)+which;?
why = for which.如：?
I was in Beijing on the day when (=on which)he arrived.?
他到的時候，當時我正在北京。?
The office where (=in which)he works is on the third floor.?
他工作的辦公室在?三樓。??
This is the chief reason why (=for which)we did it.這是我們做這事的主要原因。?
2)當先行詞是表時間的time，day等和表地點的place，house等時，一定要注意分析從句的結構，如果缺少主語或賓語時，關系詞應該用which或that,缺少時間狀語或地點狀語時，才能用when或where，試比較：?
I’ll never forget the day when my hometown was liberated.?
我將永遠不會忘記我的家鄉被解放的那一天。?
I’ll never forget the days which/that we spent together last summer.?
我將永遠不會忘記去年夏天我們共同度過的那段時光。?
3)when和where既可以引導限制性定語從句，也可以引導非限制性定語從句。而why 只能引導限制性定語從句。??
三、“介詞+關系代詞”引導的定語從句?
在這種結構中，關系代詞若是表示人時，就只能用whom；關系代詞若是表示事物時，就只能用which。
1.當介詞放在關系代詞的前面時，介詞賓語只能用which (指物)或whom 關系代詞不能省略。如：
He has found a good job for which he is qualified.?
他找到了一份他能勝任的工作。?
（qualify + 名詞+for意為“使……具有……資格”）?
The man to whom you talked just noill chair the meeting tomorro?
你剛才與他談話的那個人明天主持那個會議。（ talk to+名詞意為“與某人談話”）?
He is bargaining with the landlord over the monthly price at which the apartment rents. 他在與房東就那套公寓出租的月租金進行磋商。（名詞+rent at+表示價格的詞意為“某物以某價格出租”）
2.當介詞位于定語從句的末尾時，可用that/which(指物)，that/whom/who(指人)作介詞的賓語，而且作介詞賓語的關系代詞往往省略。如：?
This is the hero (that/who/whom)we are proud of.這就是我們引以為豪的英雄。?
This is the pen ( that/which)I wrote the letter with.這就是我用寫信的那枝筆。
3.“復合介詞短語+關系代詞which”引導的定語從句，這種結構引導的定語從句常與先行詞用逗號分開，定語從句常用倒裝語序。?
He lived in a big house，in front of which stood a big tall tree.?
他住在一所大房子里，房前有一棵大高樹。?
The monkey crossed the river，in the middle of which he was almost killed.?
那只猴子過了河，在河中央它差點淹死。?
注意：在一些固定搭配的動詞短語中，由于動詞和介詞不可分割，因此不能把介詞置于關系代詞之前。如：?
This is the pen which I’m looking for.這正是我在尋找的那枝筆。?
The boys he is looking after are very healthy. 他照看的那些小男孩都很健康。
4.介詞+關系代詞=關系副詞?
1）這就是我們去年住過的房間。?
This is the room which we lived in last year.?
This is the room in which we lived last year.?
This is the room where we lived last year.?
2)我仍然記得我入黨的那一天。?
I still remember the day on which I joined the Party.?
I still remember the day when I joined the Party.?
通過對上述知識的掌握，對于一個句子我們可用不同的表達方法表達。如：?
那就是他工作的大學。?
四、定語從句的種類以及區別
1.定語從句分為限制性定語從句和非限制性定語從句，現將它們之間的用法及區別列表如下
限制性定語從句非限制性定語從句
和先行詞的關系密切（刪去后，影響整個句子意義的表達）和先行詞的關系不密切（是一種補充說明，刪去后不影響整個句子意義的表達）
不用逗號分開一般使用逗號分開
可用關系代詞that引導不可用關系代詞that引導
可以省略（that，who，which在從句中擔當賓語時可以省略）不可以省略
可以替代（whom作賓語時，可用who或that替代）不能替代
只可以修飾先行詞，不可以修飾主句或主句的一部分修飾整個主句或主句的一部分，此時定語從句前有逗號分開，只能用which或as引導。
請看下面例句的不同含義：?
限制性：她有兩個當解放軍的兒子。?
She has two sons who are P.L.A.men.?
(aybe she has other sons who are not P.L.A.men.)?
非限制性：她有兩個兒子，他們都是解放軍。?
She has two sons，who are P.L.A.men.?
(She has only two sons.They are both P.L.A.men.)?
體會下列非限制性定語從句?
Yesterday I met Li Ping，who seemed to be busy.?
昨天我遇到了李平，他看起?很忙。??
We will put off the meeting until next week，when we won’t be so busy.?
我們將把會議推遲到下周舉行，到那時我們就不會這么忙了。
2.關系代詞which與as引導定語從句的區別?
which與as都可以引導定語從句，但它們有許多用法上的區別，現就此簡要分析如下：??
1)which與as引導非限定性定語從句的區別：?
which只能放在主句后面，而as引導的從句位置相對較靈活，可在前，可在后。如：?
As he realized，I was very useful to him.?
（在前）正像他所意識到的那樣，我對他非常有用。?
Air，as we know，is a gas.（在中）空氣，眾所周知，是一種氣體。?
He was a foreigner，as I know from his accent.?
(在后)他是個外國人，正像我從他的口音判斷的那樣。?
He came late again，which made his boss angry.?
（在后）他又晚了，這一點使得老板很生氣。?
在which引導的定語從句中，謂語動詞若是am，is，are，則這些系動詞不能省略，而as后面若是這種情況，則可以省略。如：?
He is a teacher，as (is)clear from his manner.(is可以省略)他是個老師，這從他的言談舉止可看清楚。?
He said he had never seen her before，which was not true.?
（was 不可省略）他說他從沒見過她，這一點不對。?
當which引導的從句在意義上近乎并列關系時，可以用and this，and that代替，意思是“這事”。如：?
He changed his mind，which (and this，and that)made me very angry.?
他改變了主意，這使我很生氣。?
She has married again，which (and this，and that)was unexpected.?
出乎意料的是，她又結婚了。?
而as主要起與上下連接的作用，表達說話人的看法、觀點，并指出主句內容的出處或根據等。如：?
Einstein，as we know，is a famous scientist.愛因斯坦，眾所周知，是位偉大的科學家。?
As is announced in today’s newspaper，we must improve our style of work.?
今天的報紙上說，我們必須改進工作作風。?
作主語時，which既可以作系動詞be的主語，也可以作實義動詞的主語，而as只可以作系動詞be的主語。如:?
He married her，which was natural.?
（可用as代替which）他和她結婚，這是很自然的事。??
He won a/the Nobel Prize in chemistry，which made him illustrious.?
(不可用as代替which)他獲得了諾貝爾化學獎，這使他名揚天下。?
當定語從句位于主句之后，純粹表示主句所述的內容，不帶有“如……那樣”的意思時，往往用which，而不用as。如：?
They were invited to the state banquet，which was a great honor to them.?
他們被邀請參加國宴，這對他們說是莫大的榮幸。?
We had to sleep in our wet clothes，which was most uncomfortable.?
我們不得不穿著濕衣服睡覺，這簡直太不舒服了。?
ummy always treats me just like a baby，which I can’t bear.?
媽媽老把我當成小孩子對待，這讓我無法忍受。?
當定語從句有“如同……那樣”的意思時，用as比用which更常見，而這些從句幾乎成為固定說法。如：
Things will turn out contrary to one’s wishes，as is often the case.?
事與愿違，這是常有的事。?
As was natural， this inordinate hope was followed by an excessive depression.?
這種過分希望之后，接著是極度的沮喪，是很自然的事。?
Chaucer is buried in “Poet’s Corner”，as might have been expected.?
正如人們已經預料的，喬叟被葬在“詩人角”。?
The material is elastic，as is show in the figure.這種材料有彈性，如圖所示。?
as we know眾所周知?
as has been said above/before正如前所述?
as has been pointed out正如已經指出的?
as might be imagined可以想像得到?
當定語從句的關系代詞指的是先行詞本身時，只能用which。如：?
These apple trees，which I planted three years ago，have not borne any fruit.?
這些蘋果樹是我三年前種下的，沒結出任何果實。?
The Thames，which is now clean enough to swim in，was polluted for over a hundred years.?
泰晤士河，現在已經很干凈，可以在里面游泳，它曾被污染了一百多年。?
帶介詞的典型的定語從句，必須用which，不能用as。如：?
There is a great deal of oxygen around us，without which we could not live.我們周圍有許多氧氣，沒有它我們就無法生存。?
The shed in our garden，in which we often played，has lasted for a long time.?
我們經常玩耍的花園里的那個棚子，已經有很長時間了。?
2)引導限制性定語從句時which與as的區別：?
先行詞如為表示物的名詞或代詞，在從句中又作介詞的賓語時，只能用which。如：?
This is the pan in which I boiled the milk. 這就是我煮牛奶的鍋。?
前面有as時,引導定語從句的關系代詞用as，不用which。如：?
There are as many dictionaries as are needed.所需要的字典都有了。?
前面有such時，引導定語從句的關系代詞用as,不用which。如：?
Such women as know Tom thought he was charming.?
認識湯姆的女人都認為他很?迷人。??
I have never heard such stories as he tells.他講的那些故事我從沒聽過。?
He is not such a man as I expected.他不是我期望的那種人。?
前面有the same時，引導定語從句的關系代詞用as而不用which。如：?
We are facing the same problems as we did years ago.?
我們正面臨著和多年以前同樣的困難。?
This is the same wallet as I lost.這只錢包與我丟失的那只相同。?
I have the same trouble as you have.我和你有著同樣的困難。?
總之，which與as引導定語從句的區別要在實踐中多體會，體會多了，才能正確運用。??五、定語從句中的謂語動詞與先行詞保持一致的問題
1.one of+復數名詞+關系代詞+復數形動詞。如：?
Titanic is one of the most wonderful movies that have been produced in Hollywood.《泰坦尼克號》是在好萊塢拍的最好的電影之一。?
2.the (only)one of+復數名詞+關系代詞+單數形動詞。如：?
The Great Wall is the (only)one of the buildings on the earth that is seen from the moon.?
長城是地球上惟一一個從月球上能夠看到的建筑。?
3.當關系代詞as或which引導非限制性定語從句，修飾主句內容時，若as或which作主語，則從句的謂語動詞用單數形式。如：?
Great changes have taken place in China，as is known to all.?
中國發生了巨大的變化，眾所周知。?
4.其他情況?
I，who am your teacher，will try my best to help you.我，你的老師，要盡全力幫助你。?
To own a colour TV set in each family，which we thought was impossible twenty years ago，now becomes true.?
每家擁有一臺彩電，這在20年前我們認為不可能的事情，現在變成了現實。?
Have you heard of the persons and things that are being talked about??
你聽說了他們談論的人和事了嗎？??
【考點詮釋】
定語從句
考點1 “介詞+關系代詞which/whom”中介詞和關系代詞的選擇
介詞后作賓語的關系代詞為歷年高考考查的重點，一般講有兩個：指人時只能用whom，指物時只能用which。當然關系代詞作定語時也可用whose。如：
①The pen with which he wrote was made in China．他寫字用的鋼筆是中國制造的。
②The train on which Tom travelled to Canada was very fast．湯姆到加拿大去時乘坐的火車速度非常快。
③The teacher in front of whose house stands a tall tree is very patient with his students．那位老師對他的學生非常有耐心，他家的房子前面有一棵大樹。
考點2 as與which引導的非限制性定語從句的判定
1．as引導的從句表示說話人對話語的看法、態度、解釋或評論。
(1)此時的as意為“正如……，正像……”。翻譯時有時可不必譯出。如：
You are clever，as all those who know you can see．你很聰明，所有認識你的人都能看出。
(2)在句法上，as常用作一些實義動詞(如see，know，hear，watch，remember，say，tell，show，expect，guess等)的賓語，這類動詞與as幾乎成了一種固定搭配。如：
As we all know，China is becoming stronger and stronger．眾所周知，中國正變得越越強大。
(3)as引導的從句可以前置(而which引導的從句則不可)。如：
As is a fact，ike is expected to make a top student．這是一個事實，邁克有望成為一名頂尖的學生。
特別提示
主句中出現the same，such，so修飾先行詞時，要選擇as作關系代詞，在定語從句中作主語或賓語，此時as引導的是限制性定語從句。另外要注意：
(1)the same…that與the same…as引導的定語從句在意義上的區別：前者修飾的名詞與原物是同一個東西；而后者修飾的是與先行詞同類型的另一樣東西。試比較：
①This is the same bag that I lost yesterday．這正是我昨天丟失的那個書包。(同一個書包)
②This is the same bag as I lost yesterday．這個書包和我昨天丟失的那個一樣。(同類型的另一個)
(2)such/so…as…和such /so…that…結構不同，as引導定語從句，而that引導狀語從句。如：
①They talked in such simple English as children could understand．他們用孩子們能聽懂的簡單的英語交談。(定語從句，as代替先行詞simple English作understand的賓語)
②He shut the windoith such a force that the glass broke．他如此用力地關窗，結果玻璃碎了。(結果狀語從句，that引導的從句表示用力關窗導致的結果)
2．which引導的此類從句對主句所敘述的事情進行補充說明，表明事物的狀態或結果。
(1)which此時指前面主句所提到的，常譯為“這一點，這事”等。主句與從句通常要用逗號隔開，且從句只能位于被修飾句子的后面。如：
He works very well，which makes his boss satisfied．他工作干得不錯．，這使得他的老板很滿意。
(2)which在句法上一般用作實義動詞的主語，這時它所引導的從句與主句之間常含有并列、因果關系。如：
She succeeded in the competition，which satisfied her parents．她在比賽中取得成功，這使得她的父母很滿意。
(3)在從句中作定語或介詞的賓語時，要用which。如：He often works far into the night，by which time everyone else has left the office．他通常工作到深夜，到那時其他人
已下班了。
特別提示
高考一般不考查as與which引導非限制性定語從句的區別，但近年高考試題中出現過這個考點。一般說，如果從句的含義是順接主句的敘述，那么這兩個詞都可以使用；如果從句的含義是對主句的否定，或者語意不是順接的，則只能用which。如：
①He came late to school，which/as was what we had expected．他上學遲到了，這是我們意料中的。
②He came late to school，which surprised US a11．他上學遲到了，這讓我們所有人都很驚訝。(不可用as)
考點3 關系代詞、關系副詞引導定語從句的辨別
關系代詞在定語從句中充當主語、賓語或表語；而關系副詞在定語從句中充當時間、地點、原因等狀語。一般說，關系副詞在語義上相當于”介詞+which”結構。試比較：
①I’ll never forget the days which I spent with you．我不會忘記我們在一起度過的歲月。(which在定語從句中作spent的賓語)
②I’ll never forget the days when(=in which)we studied in Beijing．我永遠不會忘記我們一起在北京學習的時光。(when在定語從句中作時間狀語，studied在此處為不及物動詞，后面不再接賓語)
考點4 定語從句的間隔現象
定語從句一般緊接被它修飾的先行詞，但有時候它和先行詞之間有可能插入其他成分，使它與先行詞分隔開，這種定語從句叫做被分隔的定語從句。在這種情況下，對關系詞的準確判斷顯得相當重要，而且在閱讀時會經常遇到這種情況，在閱讀時要注意識別。一般說，定語從句被分割開大致有以下三種情況：在先行詞與定語從句之間插入一個狀語、定語，或被謂語動詞分隔開。如：
①Do you remember one afternoon ten years ago when I came to your house and borrowed a diamond necklace?你還記得十年前的一天下午，我到你家，找你借了一條鉆石項鏈嗎?
(先行詞one afternoon與定語從句被狀語ten years ago分隔開了)
②A new teacher will eOlTle tomorroho will teach you German．明天，一位新老師將教你們德語。(先行詞a new teacher與定語從句被謂語部分和時間狀語will come tomorrow隔開了)關系代詞在下列情況下常省略：(1)作及物動詞的賓語時；(2)作介詞的賓語，當關系代詞與介詞分開使用時，可以省略。但若是關系代詞與介詞連用，則不能省略。如：
①The coat(that)I put on the desk is blue．我放在桌子上的那外套是藍色的。(作動詞put的賓語)
②who is the teacher(whom)Li ing is talking to?正在與李明談話的老師是誰?(作介詞to的賓語)
③Please tell me from whom you borrowed the English novel．請告訴我你從誰那兒借的這本英小說。(關系代詞不能省略)
有些句型結構如同位語從句、狀語從句和強調句與定語從句結構較相似，稍不認真就會出錯。
1．定語從句與同位語從句的區別
定語從句是對其先行詞的修飾或限制，屬于形容詞性從句的范疇；而同位語從句是對前面抽象名詞的進一一步說明和解釋，屬于名詞性從句的范疇。如：
①He makes a promise that if he Call get the job，he will work hard to make as much money as he can for the eompany．他許諾如果他能獲得那份工作，他將努力為公司掙盡可能多的
錢。(that引導的同位語從句是對先行詞a promise的進一步解釋和說明)
②ike’s parents made a special promise to Tom that surprisedTom．邁克的父母對湯姆許下了一個特別的諾言，這使得湯姆很驚奇。(that引導的定語從句是對先行詞promise的修飾和限制)
2．定語從句與強調句的區別
定語從句和強調句的判斷方法：若將句中的“It is/was…that/who”去掉，而句子不缺成分，結構完整，說明原句是強
調句。如：
It was in 1 998 that the flood destroyed many houses in Jiangxi．在1998年，洪水毀壞了江西地區很多的房屋。(強調句)
(判斷方法：如果去掉it was和that，剩下in 1998 the flood destroyed many houses in Jiangxi，句子結構完整，可判定原句為強調句)
3．定語從句與狀語從句的區別
定語從句在句子中作定語，修飾名詞、代詞或句子；并且，這個被修飾的名詞、代詞或句子稱為先行詞，通常放在定語從句之前。狀語從句在句子中作狀語，修飾動詞；通常不同的狀語從句有不同的連詞，位置較靈活，通常放在句首或句末，有時也放在句中。
以where為例說明：
①Let’s have a short meeting where we met last time．我們在上次見面的地方開個短會吧。(Where we met last time是地點狀語從句，在句中作地點狀語，表示開會的地方)
②This is the place where we had a meeting last time．這就是我們上次開會的地方。(Where we had a meeting last time是定語從句，在句中作定語修飾the place)
