初中定语从句讲解

1、初中定语从句总结一、定义：在复合句中，修饰某一名词或代词的从句叫做定语从句。定语 定语用来限定、修饰名词或代词的，是对名词或代词起修饰、限定作用的词、短语（动词不定式短语、动名词短语和分词短语）或句子，汉语中常用的表示。主要由形容词担任，此外，名词，代词，数词，分词，副词，不定式以及介词短语也可以来担任，也可以由一个句子来担任。单词作定语时通常放在它所修饰的词之前，作前置定语。短语和从句作定语时则放在所修饰的词之后，作后置定语。 定语从句是指在一个句子中作定语的句子，定语从句要放在所修饰的词后。如：1) The man who lives next to us is a policeman.

2、2) You must do everything that I do. 上面两句中的man和everything是定语从句所修饰的词，叫先行词，定语从句放在先行词的后面。引导定语从句的词有关系代词that, which, who(宾格who, 所有格whose)和关系副词where, when、why关系词常有三个作用：1、引导定语从句 2、代替先行词 3、在定语从句中担当一个成分二、关系代词引导的定语从句1.who指人，在从句中做主语(1)The boys who are playing football are from Class One.(2)Yesterday I helped a

3、n old man who lost his way.2. whom指人，在定语从句中充当宾语，常可省略。(1) Mr. Liu is the person (whom) you talked about. 注意：关系代词whom在口语和非正式语体中常用who代替，可省略。(3) The man who/whom you met just now is my friend.3. which指物，在定语从句中做主语或者宾语，做宾语时可省略 (1) Football is a game which is liked by most boys. ( which 在句子中做主语) (2) This i

4、s the pen (which) he bought yesterday. ( which 在句子中做宾语)4. that指人时，相当于who或者whom；指物时，相当于which。在宾语从句中做主语或者宾语，做宾语时可省略。 (5) The people that/who come to visit the city are all here. (在句子中做主语) (6) Where is the man that/whom I saw this morning? (在句子中做宾语)5. whose通常指人，也可指物，在定语从句中做定语 (1) He has a friend whose

5、father is a doctor. (2) I lived in a house whose roof has fallen in. whose指物时，常用以下结构来代替(3)The classroom whose door is broken will soon be repaired.=The classroom the door of which is broken will soon be repaired.(5)Do you like the book whose color is yellow?=Do you like the book the color of which i

6、s yellow?注：that 用法 (1)不用that的情况 (a) 在引导非限定性定语从句时。 (错)The tree, that is four hundred years old, Is very famous here. (b) 介词后不能用。 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作为定语从句的关系代词的情况 (a) 在there be 句型中，只用that，不用which。 (b) 在不定

7、代词，如：anything, nothing, the one, all等作先行词时，只用that，不用which。 (c) 先行词有the only, the very,the same,the last,just修饰时，只用that。 (d) 先行词为序数词、数词、形容词最高级时，只用that,不能用which。. (e) 先行词既有人，又有物时。 (f) 先行词指物，在主句中作表语时 (g) 为了避免重复 (h)先行词是the way或the reason时，that可作关系副词，也可省略 (i) 主句的主语是疑问词who /which时 举例： Is this the book tha

8、t you borrowed in the library? 这是你在图书馆借的那本书吗？ Who that break the window should be punished 谁打碎了窗户都要受到惩罚 All that is needed is a supply of oil. 所需的只是供油问题。 Finally, the thief handed everything that he had stolen to the police. 那贼最终把偷的全部东西交给了警察。 三、关系副词引导定语从句 关系副词 关系副词：在句中作状语 关系副词=介词+关系代词 why=for which

9、where=in/ at/ on/ . which (介词同先行词搭配) when=during/ on/ in/ . which (介词同先行词搭配) 1. where指地点，在定语从句中做地点状语用来表示地点的定语从句。 (1) Shanghai is the city where I was born. (2) The house where I lived ten y ears ago has been pulled down. 2. when引导定语从句表示时间。在定语从句中做时间状语也可做连接词用 (1) I still remember the day when I first

10、came to the school. (2) The time when we got together finally came.注表示时间“time一词的定语从句只用when引导，有时不用任何关系代词，当然也不用that引导。 By the time you arrived in London, we had stayed there for two weeks. 到你到达伦敦的时候，我们在那里已经待了两个星期。 I still remember the first time I met her. 我仍然记得我第一次见到她。 Each time he goes to business t

11、rip, he brings a lot of living necessities, such as towels, soap, toothbrush etc。 每一次他去出差，他带来了生活必需品，如毛巾，肥皂，牙刷等，很多。 3. why指原因 在定语从句中做原因状语 (1) Please tell me the reason why you missed the plane. (2) I dont know the reason why he looks unhappy today. 注意：关系副词引导的从句可以由“介词+关系代词”引导的从句替换 (1) The reason why/

12、for which he refused the invitation is not clear, (2) From the year when/in which he was going to school he began to know what he wanted when he grew up. 注：1）介词后面的关系代词不能省略。 2）that前不能有介词。 3） 某些在从句中充当时间，地点或原因状语的介词+关系词结构可以同关系副词when ,where和why 互换。 This is the house in which I lived two years ago. This i

13、s 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? This is the reason why he came late. This is the reason for which he came late. 四、关系代词和冠词副词引导的从句有什么区别？关键点：1、关系副词在从句中是做状语，记住，只做状语，不能做其他的成分。2、关系副词引导的从句可以由“介词

14、+关系代词”引导的从句替换。如：the reason why he refused the invitation is clear.=The reason for which he refused the invitation is clear.Great changes have taken place in the city where I was born.=Treat changes have taken place in the city in which I was born.The time when we got tegether finally came.=The time

15、in which we got together finally came.样板题一：1、He has forgotten the day _ he arrived. A. when B. where C. that D. which解题思路：此题中，从句是he arrived，它已经是一个完整的句子，因此，这里要填一个在从句中充当状语的成分，C选项和D选项都不能做在从句中作状语，因此排除掉，the day指的是时间，因此，要填上表示时间的关系副词when。练习题：1、The moon is a world _ there is no life.A.that B. which C. where

16、 D. why2、Nobody knows the reason _ she didnt come to the meeting. A. that B. which C. why D. when3. This is the place _I have ever visited. A. there B. when C. where D. which4.

This is the house _ our beloved Premier Zhou once lived and worked. A. which B. that C. when D. where8. He didnt tell me the place _ he was born. A. th

18、at B. which C. when D. Where样板题二：用关系代词或关系副词将下列每对句子连成一个复合句The boy is my younger brother. He was here a minute ago.解题思路：所谓定语从句，就是把两句话压缩成一句话，而且，这两句话肯定辉提到同一个东西，因此，首先要找两句话都提到了的东西，此题中，两句话都提到了同一个东西一个人（the boy ,he）这就是共同点，人我们是用who或whom表示，两句话都是做主语，因此，只能用在从句中作主语的who,不能在从句中做宾语的whom，因此，答案是：The boy who was here a

19、 minute ago is my younger brother.练习题：1. The old man is a professor. He teaches chemistry in a college.2. The car was going 90 miles an hour. The car just passed us.3. The woman is here now. You were talking about her.4. The man waved to us. The man was my uncle.样板题三：用关系代词或关系副词将下列每对句子连成一个复合句 This is

20、 the hall. We listened to the report in it the other day.解题思路：还是找两句话都提到了的那个共同点，是the hall（it）,在第二句话中in it是做定点状语，因此可以用where代替，因此，答案是：This is the hall where we listened to the report the other day.=This is the hall in which we listened to the report the other day.练习题：1、Beijing Hotel is near Tian An Men

21、 Square. The foreign visitors live there.2、I enjoyed reading the book. You gave me a book last week.3、I prefer the subject. The subject is science.4、I spoke to the man.

26、 talking is of great importance.练习题：1. He lived in a small village, _ was a long way from the railway station. A. that B. which C. where D. when练习(一)请分析一下定语从句：( 请划出定语从句，并标出先行词)1.
