高中英語定語從句說課稿
定語從句（Attributive Clauses）在句中做定語，修飾壹個名詞或代詞。它是高中英語學習的重要語法項目之壹，也是歷年高考的熱點。如下是我給大家整理的高中英語定語從句說課稿，希望對大家有所作用。
Ⅰ.概念：
(1) 定語從句：在主從復合句中用作定語的從句叫定語從句。定語從句壹般緊接在先行詞後面。
(2) 先行詞：被定語從句修飾的成份。先行詞可以為壹個詞，短語，或整個主句。
(3) 引導定語從句的詞叫關系詞，分為關系代詞和關系副詞。
關系詞的作用：
1) 引導定語從句，連接主句和從句，相當於壹個連詞；
2) 必在從句中作某個句子成份（可以做主語，賓語，表語，定語，狀語）
常用的關系代詞: that、 which、 who、whom、as , 在從句中作主語，賓語，whose在從句中作定語)
常用的關系副詞（在從句中只作狀語）: when、why、 where
The student who answered the question was John.
I know the reason why he was so angry.
The boy (whom) you are talking to is my brother.
I'd like a room whose window looks out over the sea.
定語從句三步：
第壹找出先行詞；
第二看先行詞在定語從句中的語法功能（做主語、賓語或狀語）；
第三選擇合適的關系詞。
Ⅱ. 幾個關系代詞的基本用法：
●that: 可指人或物；在定語從句中作主語，賓語，表語。(指人時，相當於who或 whom；指物時，相當於which)(不用於非限制性定語從句; 不可置於介詞後作賓語) 如：
1. Do you know the gentleman that/who spoke just now?
2. You can take anything ( that) you like.
3. What is the question (that/which) they are talking about?
4. Here is the man ( who/whom/that ) you want to see.
5. She's no longer the girl ( that) she used to be before.
●which: 指物；在定語從句中作主語，賓語，表語，定語。如：
1. The bookwhich/that was on the desk was bought by my father.
2. The book (which/that) I bought yesterday is very interesting.
3. The factory in which his father works is far from here.
●who, whom, whose:
who: 主格, 在從句中作主語，在口語或非正式用法中作賓語; 只可指人
whom: 賓格，在從句中作賓語; 只可指人
whose: 屬格，在從句中作定語，可指人也可指物。
1. I like the students who/that work hard.
2. All who heard the story were amazed.
(代詞如he, they, any, those, all, one等後多用who.)
3. He's a man from whom we should learn.
= He's a man (whom/who/that) we should learn from.
4. A child whose parents are dead is called an orphan.
5. I'd like a room whose window faces south.
=I'd like a room of which the window faces south.
=I'd like a room the window of which faces south.
關系代詞作介詞賓語： （介詞+ whom / which）
關系代詞在定語從句中用作介詞賓語時, 介詞可放於從句之首, 也可放於從句之末. 但以放於句首較為正式.（介詞前置，必須註意不影響動詞詞組的含義。）
1. This is the book for which you asked. =This is the book (that/which) you asked for.
2. Do you know the person with whom I shook hands？
= Do you know the person (whom/who/that) I shook hands with?
3. Is this the factory to which you paid a visit last week?
4. Is this factory the one to which you paid a visit last week?
5. This is the girl whom they are looking after. (介詞after與look構成固定詞組，不可前置。look at, look for, look after, take care of等)
●as 的.用法:(as 引導定語從句, 在定語從句中作主語、賓語、表語)
①如為限制性的，多用於the same …as ; the same as；such …as …; as many/much as；so …as等結構中。
1. I have the same book as you (have). 我有壹本和妳的壹樣的書。
2. .---Why didn't you mention that in face of the police just now?
--- I thought it was such a minor detail as was hardly worth mentioning.
3. Don't do such things as you are not sure about.
比較：I live in the same house that he used to live in.
I'm wearing the same shirt as you wore yesterday.
比較：Here is so big a stone as no one can lift. （定語從句）
Here is so big a stone that no one can lift it.（結果狀語從句）
②如為非限制性的，多單獨引導壹個定語從句，這種定語從句可置於句首，句中或句尾，譯為"正如，這壹點"。（動詞常為know, see, expect, point out, etc.）
As we all know, smoking is harmful to one's health . (as 作賓語)
=As is known to all, smoking is harmful to one's health . （as 作主語）
=It's known to all that smoking is harmful to one's health .
=Smoking is harmful to one's health, as we all know .（as 作賓語）
=Smoking, as we all know, is harmful to one' health.
He was a foreigner, as I knew from his accent. (賓語, 先行詞是前面整個句子)
Ⅲ. 關系副詞引導的定語從句:
●When 指時間，在定語從句中作時間狀語。其先行詞是表時間的名詞（如：time, day, week, tear, month, etc.）
He came last night when I was out.
We will put off the picnic until next week, when the weather would be better.
註意：先行詞為"時間名詞"，可用when引導定語從句，when在定語從句中作狀語；還可以用which或that 引導，which或that在從句中作主語或賓語。
比較:1. I still remember the day when /on which my brother joined the army.（作狀語）
2. I still remember the days which/that we spent together. （作賓語）
3. I shall never forget the day when Shen Zhou Ⅴ was launched, which has a great effect on my life.
●Where 指地點，在定語從句中作地點狀語。其先行詞是表示地點的名詞，如：place, school, factory, room, etc.
This is the place where I was born.
I live in the room where /in which he used to live.
註意：先行詞是"地點名詞"，定語從句可用where引導，還可用which或that引導，which/that 在從句中作主語或賓語。
比較: ※1. This is the factory where /in which he worked last year. （作狀語）
2. I think you have got to the point where a change is needed, or you would fail.
3. He's got himself into a dangerous situation where he's likely to lose control of the plane.
4. This is the park which/that they visited last year. （作賓語）
●Why 指原因，在定語從句中作原因狀語。先行詞為reason 時，可用for which指代；當關系詞在從句中作主語或賓語時，則用which或that 引導。如：
1. The reason why / for which / (that) he didn't attend the meeting was that he was ill.
2. I don't believe the reason (that/which) he gave me. （作賓語）
3. Have you asked him the reason that may explain his success? （作主語）
當先行詞為way時，the way在從句中作狀語時，定語從句常用that, in which,或how引導，that常可以省略。
the way在從句中作主語或賓語時，則用which或that 引導。如:
This is the way (that) /in which I do such things.
比較: Please do the experiment in the way （that/which）I have shown you.
Ⅳ. 限制性定語從句與非限制性定語從句的區別：
1. 形式上，非限制性定語從句往往用逗號隔開。
2. 語法上，非限制性定語從句壹般不用that.
3. 語義上，限制性定語從句與先行詞關系緊密，起限定作用，如果去掉了這個定語從句，整個句子就不完整或者會改變意思；而非限制性定語從句與先行詞關系不是很緊密，對先行詞起補充說明或描述的作用。
This is the book I like best. 這就是我最喜歡的那本書。
Beijing, which has been China's capital for more than 800 years, is rich in cultural and historic relics. 北京是中國八百年之久的古都，它有著豐富的文化和歷史遺產。
4. 翻譯時，限制性定語從句可譯為壹句（較短的壹般譯為"的"字結構）；而非限制性定語從句可譯為兩句。（見上句翻譯）
比較: He has a sister, who is a musician.
He has a sister who is a musician.
引導非限制性定語從句的關系代詞，指人時用who, whom, whose , 指物時用which , whose; 關系副詞when，where, why, etc.
1. He studied hard at school when he was young, which leads to his success in his later life.
2. Tom's father, who arrived just now, is a famous scientist.
Ⅴ. 幾個易混淆的關系代詞的比較:
●that & which:
在定語從句中，which 和that 在指代事物時，壹般可以互換使用，但並非在任何情況下都是這樣，這裏介紹宜用that, 而不宜用which 的情況.
①先行詞為不定代詞,all, much, something, everything, anything, nothing, none, the one等,
1.We should do all that is useful to the people .
2.There's nothing that can be said about it .
3.Do you mean the one that was bought yesterday?

2.The rider and his bike that had run over an old woman were held up by the police.
⑥被修飾詞為數詞時.
1.Yesterday I caught two fish and put them in a basin of water .Now you can see the two that are still alive .
⑦如果有兩個從句，其中壹個關系代詞已用which ,另壹個關系代詞宜用that，以避免語言的單調或重復。
Edison built up a factory which produced things that had never been seen before.
⑧疑問詞是who或which，關系代詞宜用that，以避免重復。
1. Which is the book that you like best?
2. Who is the man that is standing at the gate?
⑨主句是There be 結構，修飾其主句的定語從句宜用that 作關系代詞. 如：
1. There is still a seat in the corner that is still free.
⑩被修飾成分為表語時，或者關系代詞本身是定語從句的表語時,該關系代詞宜用that .
1. That's a good book that will help you a lot.
2. My home village is no longer the place ( that ) it used to be .
定語從句中宜用which而不宜用that 的情況:
①當關系代詞的前面有介詞時.

●as & which:
as & which 引導非限制性定語從句的區別：
①位置的不同：
which 引導的定語從句只置於所限制的句子後；as 位置較靈活，也就是說as可置於所限制的句子前面；插在句子中或放在句子後。如：
1. He was late again, which made his teacher very angry.
2. Jack, as you know, is an honest man. 或Jack is an honest man , as you know.
或As you know, Jack is an honest man.

1. She was very patient towards the children, which her husband seldom was.
2. He was proud, which I dislike very much.（先行詞是壹個句子）
3. He is an honest man, as is known to all.

as we all know；as you know; as is known to all; as you see; as we can see; as has been expected; as we have imagined.
高中英語定語從句句型總結
壹、疑問句中考查定語從句
1. Is this the farm ________ you visited last week？
A. whereB. the oneC. on whichD. /
解析答案是D。命題人經常利用疑問句的特殊結構來幹擾學生的正確選擇。遇到這類定語從句時，最好的辦法是先把疑問句還原成陳述句，然後判斷誰是先行詞，再看關系詞在定語從句中所充當的成分，最後確定正確答案。
二、倒裝句中考查定語從句
2. We came to a place， ________ stood a big tower.
A. whichB. thatC. /D. where
解析正確答案是D。為了保持句子平衡，句子用了倒裝語序。倒裝的使用使定語從句的結構變得較為特殊，因此對於使用倒裝語序的定語從句，應先把倒裝語序還原成正常語序，這樣句子結構就比較清晰了。
三、 拆分詞組和固定搭配
3. The second is connected with the use ________ the body makes of food.
A. of whichB. whereC. to doD. that
4. Why can’t you realize the part ________ they have played in our life？
A. whichB. on whichC. whenD. where
解析正確答案分別是D和A。壹些詞組和搭配被拆開後，句子的含義就變得難以理解。首先把拆開的詞組復原是理解此類定語從句的關鍵。上述句子中包含以下詞組：make use of， play a part (in)。
四、添加插入語或狀語
5. The scientist has made another discovery， _______ I believe is of great importance.
A. thatB. /C. whichD. why
解析應選擇C。這類句子主要利用插入語或狀語的添加來增加試題的難度。常見的插入語有：I think (suppose， expect， believe， imagine)， in my opinion， to tell you the truth等。做這類題目時，最佳的辦法是先刪去插入語或狀語，這樣句子的主幹部分就壹目了然了。
五、插入非謂語動詞
6. Is this the man ________ you want to have ________
the radio for me？
A. who；repairedB. that；repaired
C. whom；repairingD. that；repair
解析D項正確。非謂語動詞是英語中難度較大的語法項目之壹，因而在定語從句中加入非謂語動詞就成了學生最易失分的題目。對付這類題目最有效的辦法就是將句子還原。如：我們可以把幾個句子中的定語從句進行還原，還原後的句子應是：You want to have the man repair the radio for me.
