高考英语语法考点

高中英语定语从句说课稿

答如下：

1. 宾语从句置于及物动词或介词之后，作动词或介词的宾语。引导宾语从句的词有连接词(that, if, whether) 、连接代词(what , which, who, whom, whose等)和连接副词how, when, where, why等)。例如：

I know that he is ill.

Can you tell me where he lives?

I wonder if / whether he will go.

We don't know whose wallet it is.

Tom is interested in what you said.

注意：that或if从句通常不作介词的宾语(except除外)。例如：

I am not sure about whether (不用if) he will go.

The house is beautiful except that it is a little small.

2. 定语从句置于所修饰的名词或代词之后 ，它在句中用来作定语，修饰前面的名词。被定语从句修饰的名词叫先行词。引导定语从句的词有关系代词(that , which,who, whom, whose等)和关系副词(when, where, why等)。关系代词指代前面的名词，在定语从句中可以作主语、宾语和定语; 关系副词在定语从句中可以作状语，表示时间、原因、地点等。

高中英语定语从句说课稿

　定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词。它是高中英语学习的重要语法项目之一，也是历年高考的热点。如下是我给大家整理的高中英语定语从句说课稿，希望对大家有所作用。

　 Ⅰ.概念：

　(1) 定语从句：在主从复合句中用作定语的从句叫定语从句。定语从句一般紧接在先行词后面。

　(2) 先行词：被定语从句修饰的成份。先行词可以为一个词，短语，或整个主句。

　(3) 引导定语从句的词叫关系词，分为关系代词和关系副词。

　关系词的作用：

　1) 引导定语从句，连接主句和从句，相当于一个连词；

　2) 必在从句中作某个句子成份（可以做主语，宾语，表语，定语，状语）

　常用的关系代词: that、 which、 who、whom、as , 在从句中作主语，宾语，whose在从句中作定语)

　常用的关系副词（在从句中只作状语）: 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.

　定语从句三步：

　第一找出先行词；

　第二看先行词在定语从句中的语法功能（做主语、宾语或状语）；

　第三选择合适的关系词。

　 Ⅱ. 几个关系代词的基本用法：

　●that: 可指人或物；在定语从句中作主语，宾语，表语。(指人时，相当于who或 whom；指物时，相当于which)(不用于非限制性定语从句; 不可置于介词后作宾语) 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；在定语从句中作主语，宾语，表语，定语。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, 在从句中作主语，在口语或非正式用法中作宾语; 只可指人

　whom: 宾格，在从句中作宾语; 只可指人

　whose: 属格，在从句中作定语，可指人也可指物。

　1. I like the students who/that work hard.

　2. All who heard the story were amazed.

　(代词如he, they, any, those, all, one等后多用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.

　关系代词作介词宾语： （介词+ whom / which）

　关系代词在定语从句中用作介词宾语时, 介词可放于从句之首, 也可放于从句之末. 但以放于句首较为正式.（介词前置，必须注意不影响动词词组的含义。）

　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. (介词after与look构成固定词组，不可前置。look at, look for, look after, take care of等)

　●as 的.用法:(as 引导定语从句, 在定语从句中作主语、宾语、表语)

　①如为限制性的，多用于the same …as ; the same as；such …as …; as many/much as；so …as等结构中。

　1. I have the same book as you (have). 我有一本和你的一样的书。

　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.

　比较：I live in the same house that he used to live in.

　I'm wearing the same shirt as you wore yesterday.

　比较：Here is so big a stone as no one can lift. （定语从句）

　Here is so big a stone that no one can lift it.（结果状语从句）

　②如为非限制性的，多单独引导一个定语从句，这种定语从句可置于句首，句中或句尾，译为"正如，这一点"。（动词常为know, see, expect, point out, etc.）

　As we all know, smoking is harmful to one's health . (as 作宾语)

　=As is known to all, smoking is harmful to one's health . （as 作主语）

　=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 作宾语）

　=Smoking, as we all know, is harmful to one' health.

　He was a foreigner, as I knew from his accent. (宾语, 先行词是前面整个句子)

　 Ⅲ. 关系副词引导的定语从句:

　●When 指时间，在定语从句中作时间状语。其先行词是表时间的名词（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.

　注意：先行词为"时间名词"，可用when引导定语从句，when在定语从句中作状语；还可以用which或that 引导，which或that在从句中作主语或宾语。

　比较:1. I still remember the day when /on which my brother joined the army.（作状语）

　2. I still remember the days which/that we spent together. （作宾语）

　3. I shall never forget the day when Shen Zhou Ⅴ was launched, which has a great effect on my life.

　●Where 指地点，在定语从句中作地点状语。其先行词是表示地点的名词，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.

　注意：先行词是"地点名词"，定语从句可用where引导，还可用which或that引导，which/that 在从句中作主语或宾语。

　比较: ※1. This is the factory where /in which he worked last year. （作状语）

　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. （作宾语）

　●Why 指原因，在定语从句中作原因状语。先行词为reason 时，可用for which指代；当关系词在从句中作主语或宾语时，则用which或that 引导。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. （作宾语）

　3. Have you asked him the reason that may explain his success? （作主语）

　当先行词为way时，the way在从句中作状语时，定语从句常用that, in which,或how引导，that常可以省略。

　the way在从句中作主语或宾语时，则用which或that 引导。如:

　This is the way (that) /in which I do such things.

　比较: Please do the experiment in the way （that/which）I have shown you.

　 Ⅳ. 限制性定语从句与非限制性定语从句的区别：

　1. 形式上，非限制性定语从句往往用逗号隔开。

　2. 语法上，非限制性定语从句一般不用that.

　3. 语义上，限制性定语从句与先行词关系紧密，起限定作用，如果去掉了这个定语从句，整个句子就不完整或者会改变意思；而非限制性定语从句与先行词关系不是很紧密，对先行词起补充说明或描述的作用。

　This is the book I like best. 这就是我最喜欢的那本书。

　Beijing, which has been China's capital for more than 800 years, is rich in cultural and historic relics. 北京是中国八百年之久的古都，它有着丰富的文化和历史遗产。

　4. 翻译时，限制性定语从句可译为一句（较短的一般译为"的"字结构）；而非限制性定语从句可译为两句。（见上句翻译）

　比较: He has a sister, who is a musician.

　He has a sister who is a musician.

　引导非限制性定语从句的关系代词，指人时用who, whom, whose , 指物时用which , whose; 关系副词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. 几个易混淆的关系代词的比较:

　●that & which:

　在定语从句中，which 和that 在指代事物时，一般可以互换使用，但并非在任何情况下都是这样，这里介绍宜用that, 而不宜用which 的情况.

　①先行词为不定代词,all, much, something, everything, anything, nothing, none, the one等,

　2.The rider and his bike that had run over an old woman were held up by the police.

　⑥被修饰词为数词时.

　1.Yesterday I caught two fish and put them in a basin of water .Now you can see the two that are still alive .

　⑧疑问词是who或which，关系代词宜用that，以避免重复。

　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 结构，修饰其主句的定语从句宜用that 作关系代词. 如：

　1. There is still a seat in the corner that is still free.

　⑩被修饰成分为表语时，或者关系代词本身是定语从句的表语时,该关系代词宜用that .

　1. That's a good book that will help you a lot.

　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.

　高中英语定语从句句型总结

　一、疑问句中考查定语从句

　1. Is this the farm ________ you visited last week？

　A. whereB. the oneC. on whichD. /

　解析答案是D。命题人经常利用疑问句的特殊结构来干扰学生的正确选择。遇到这类定语从句时，最好的办法是先把疑问句还原成陈述句，然后判断谁是先行词，再看关系词在定语从句中所充当的成分，最后确定正确答案。

　二、倒装句中考查定语从句

　2. We came to a place， ________ stood a big tower.

　A. whichB. thatC. /D. where

　解析正确答案是D。为了保持句子平衡，句子用了倒装语序。倒装的使用使定语从句的结构变得较为特殊，因此对于使用倒装语序的定语从句，应先把倒装语序还原成正常语序，这样句子结构就比较清晰了。

　三、 拆分词组和固定搭配

　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

　解析正确答案分别是D和A。一些词组和搭配被拆开后，句子的含义就变得难以理解。首先把拆开的词组复原是理解此类定语从句的关键。上述句子中包含以下词组：make use of， play a part (in)。

　四、添加插入语或状语

　5. The scientist has made another discovery， _______ I believe is of great importance.

　A. thatB. /C. whichD. why

　解析应选择C。这类句子主要利用插入语或状语的添加来增加试题的难度。常见的插入语有：I think (suppose， expect， believe， imagine)， in my opinion， to tell you the truth等。做这类题目时，最佳的办法是先删去插入语或状语，这样句子的主干部分就一目了然了。

　五、插入非谓语动词

　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项正确。非谓语动词是英语中难度较大的语法项目之一，因而在定语从句中加入非谓语动词就成了学生最易失分的题目。对付这类题目最有效的办法就是将句子还原。如：我们可以把几个句子中的定语从句进行还原，还原后的句子应是：You want to have the man repair the radio for me.
