1、Unit15 定語從句語法考點超級歸納
在復合句中作定語的句子叫作定語從句（Attributive Clause）。引導定語從句的有關(guān)系代詞who, that, which等，關(guān)系副詞when, where, why等。定語從句一般放在它所修飾的名詞、代詞等之后，這個名詞或代詞被稱作先行詞。定語從句可分為限制性定語從句和非限制性定語從句。
考點一：關(guān)系代詞引導的定語從句
關(guān)系代詞代替前面的先行詞，并且在定語從句中充當句子成分，可以作主語、賓語、定語等。常見的關(guān)系代詞有：who, that, which。它們的主格、賓格和所有格如下表所示：

關(guān)系副詞
用法說明
例句
when
關(guān)系副詞when代替的先行詞表示的是時間，when在定語從句中作時間狀語

13、months）

This is the place where Li Bai once
15、 lived.這是李白曾經(jīng)生活過的地方。（where先行詞是place）（此句不可將where改為that，因為that不能作為表示地點的關(guān)系副詞。試比較：This is the place that Li Bai once visited.這是李白曾經(jīng)游覽過的地方。that的先行詞同樣是place，但這個that是關(guān)系代詞，在定語從句中作賓語，可省略，還可用which替換）
Stephen Hawking believes that the earth is unlikely to be the only planet wherelife has developed gradually.斯
16、蒂芬.霍金認為地球不可能是唯一有生命的星球。

The reason why I am phoning you is to ask you whether you have got my email.我打電話給你的原因是想問問你是否收到了我的電子郵件。（why先行詞是reason，當代英語里why可以用that替代，這時關(guān)系代詞that就變成了表示原因的關(guān)系副詞，還可以將why省略）

這就是他為什么上學遲到的原因。（w
17、hy先行詞是reason，why可用that替代，還可以省略）
注意：如果上面的句子將the reason省略，那么這個句子就變成了（This is why he came late to school. ）表語從句，句子意思絲毫未變。
小貼士：
一句多譯：他出生的那天是元旦。
① The day on which he was born was New Year’s Day.
② The day which he was born on was New Year’s Day.
③ The day that he was born on was New Year’s Day.

④ The day he was born on was New Year’s Day.
⑤ The day when he was born was New Year’s Day.
⑥ The day that he was born was New Year’s Day.

1）關(guān)系副詞when, where, why有時可以省略。例如：She will never forget the day (when) her mother died. 她永遠也忘不了她母親去世的那一天。This i
19、s the factory (where) I worked three years ago. 這是我三年前工作過的工廠。The reason (why) he came late was that he got up late. 他來得晚的原因是起床晚了。

當關(guān)系代詞作介詞賓語時，就出現(xiàn)了“介詞＋關(guān)系代詞”引導的定語從句。作介詞賓語的關(guān)系代詞通常用which和whom，不能用that。“介詞＋wh
21、ich”引導的定語從句修飾指物的先行詞，“介詞＋whom”引導的定語從句修飾指人的先行詞。

注：
1）“介詞＋關(guān)系代詞”結(jié)構(gòu)中介詞的確定：介詞的確定遵循兩個原則：一是根據(jù)從句中的謂語動詞與先行詞的習慣搭配，二是根據(jù)介詞與先行詞的習慣搭配。例如：It was a prison from which no one escaped. 那是一個任何人也逃不了的監(jiān)獄。The other two areas in which the two varieties differ are spelling and pronunciation. 兩種英語中另外兩個領(lǐng)域的區(qū)別是拼寫和發(fā)音。
注：
2）“介詞＋whic
24、h”有時可與相應的關(guān)系副詞互換。例如：Is this the school in which (=where) you studied ten years ago? 這就是你10年前學習過的學校嗎？I’ll never forget the day on which (=when) I first met her. 我永遠不會忘記我第一次遇見她的那一天。The reason for which (=why) she was absent was that she missed the train. 她遲到的原因是沒有趕上火車。

I called him by the wrong name, for which mistake I
26、should apologize. 我把他的名字叫錯了，對此錯誤我應當?shù)狼浮?
5）way（方式）為先行詞時，并且關(guān)系詞在從句中作狀語，則定語從句的引導詞用in which, that或者省略。例如：I don’t like the way (in which / that) you talked to me. 我不喜歡你和我講話的方式。
6）time（次數(shù)）為先行詞時，定語從句用that引導，或?qū)hat省略。例如：It was the first time (that) Helen had understood such a complex word – a word for somet
27、hing she couldn’t touch. 海倫第一次理解了這樣一個復雜的單詞——一個她不能觸摸不到的代表某物的單詞。
小貼士：
一句多譯：剛才我們校長同他談話的那個人是我們的英語老師。
① The man to whom our headmaster talked just now is our English teacher.
② The man whom our headmaster talked to just now is our English teacher.
③ The man who our headmaster talked to just now is
28、 our English teacher.
④ The man that our headmaster talked to just now is our English teacher.
⑤ The man our headmaster talked to just now is our English teacher.
第⑤句簡潔、自然，所以口語中較常用。
考點四：關(guān)系代詞as引導的定語從句
as是個比較特殊的關(guān)系代詞，一是用在某些句型搭配里；二是獨立于主句之外。
用法說明
例句
在固定搭配as…as, so…as, such…as, the same…as中，as引導
29、定語從句
You may take as many books as you want.你想要拿多少書就拿多少。（第一個as是副詞，修飾many的；第二個as才是關(guān)系代詞，代替先行詞books，在定語從句中作賓語）
I have got such a computer as yours.我有一臺你這樣的電腦。（as是關(guān)系代詞，代替先行詞computer，在定語從句中作表語，因為yours后省略了is ）
I have never seen so beautiful a place as Guilin.我從未見過像桂林那樣美麗的地方。（as是關(guān)系代詞，代替先行詞place，在定語從句中作表
30、語，因為Guilin后省略了is ）
獨立于主句之外，as引導定語從句
As we know,
the earth turns around the sun.正如我們所
知，地球圍繞太陽旋轉(zhuǎn)。

31、

注：
as和which引導非限制性定語從句的區(qū)別：
1）as 引導的非限制性定語從句可置于主句前，而which不可置于主句前。試比較：
As you know, if you do the same thing over and over again, you begin to do it automatically. 你知道，如果你反復做同樣的事，你就會自動地去做了。
And our porters carry yo
32、ur luggage, which means that you can simply enjoy the experience. 有搬運工為你搬運行李，這意味著你能盡情地享受旅行。
2）as引導非限制性定語從句時有“正如”之意，而which沒有此意。
3）as在從句中作主語時，謂語中一般有系動詞be。否則用關(guān)系代詞which。試比較：
It was raining heavily last night, which prevented me from going to the party. 昨夜雨下得很大，使得我無法參加晚會。
Smoking is harmful to one’s
33、health, as is known to us all. 正如我們大家所知道的，吸煙有害健康。
考點五：限制性定語從句和非限制性定語從句

36、s grandfather. 小時候，杰克上的是鄉(xiāng)村學校，這個學校是以他祖父命名的。

His brother, who is nineteen years old, is serving in the army now.他的哥哥，今年十九歲，現(xiàn)在部隊服役。（表明他只有一個哥哥）
注：
1）關(guān)系代詞that不能引導非限制
37、性定語從句。
2）在非限制性定語從句中，關(guān)系代詞作賓語時不能省略。例如：She was eager to see her mother, whom she hadn’t seen for two years. 她急于見到她的母親，她有兩年沒見到母親了。
3）定語從句的位置
定語從句一般置于先行詞之后。有時，定語從句與先行詞之間插入其他成分。例如：

38、ds that consists of gestures, facial expressions and body movements that greatly add to – and sometimes even replace – spoken language. 這是一種沒有詞語，由手勢、面部表情和身體動作組成的語言，它極大地豐富了——有時甚至取代了——口頭語言。
4）that引導的定語從句和同位語從句的區(qū)別
在定語從句中，that作主語或賓語；在同位語從句中，that不作任何成分。試比較：

39、an. 沒有跡象表明查爾斯是個有錢人。（同位語從句）
They find signs that make them believe other humans before them have traveled to the Earth’s centre. 他們發(fā)現(xiàn)了一些跡象，這使他們相信，在他們之前已經(jīng)有其他人到地心旅行過。（定語從句）
5）定語從句與強調(diào)句型的區(qū)別
去掉強調(diào)句型中的It is / was和that / who后，句子成分仍然完整；去掉定語從句中的It is / was和that / who后，句子成分殘缺不全。試比較：
It was at this time yesterday that we pulled up at a mountainside store. 昨天的這個時候我們在山腰上的商店旁停了車。（強調(diào)句型）
