定语从句精讲精练一、定义:在复合句中修饰名词或代词的句子在复合句中充当定语,所以叫作定语从句。

先行词:定语从句所修饰的名词或代词。

二、位置:名词+定语从句代词限制性定语从句:先行词+定语从句三、定语从句的种类:非限制性定语从句:先行词,+定语从句注意:that不能引导非限制性的定语从句。

四、语法术语:1、关系词:引导定语从句的词叫关系词。

关系代词:作主语(who/that/which);作宾语(who/whom/that/which);作定语(whose)关系词关系副词:作状语。

where作地点状语;when作时间状语;why作原因状语;in which/that/x作方式状语词义:相当于先行词的词义或与先行词的词义相关。

关系词的词义和作用作用:连接定语从句;在句中充当成分。

2、先行词:被定语从句所修饰的名词或代词叫先行词。

五、关系词的确定:关键在于先找出定语从句,然后划分定语从句的句子成分。

1、当先行词指人,定语从句中差主语时用who/that,不能省略。

当先行词指物,定语从句中差主语时用which/that,不能省略。

当先行词既指人又指物,定语从句中差主语时用that,不能省略。

如:The man who /that came is Mike.This is the pen which/that was given by my friend.The bike and its rider that had run over (撞倒了)an old man were taken to the police station. 2、当先行词指人,定语从句中差宾语时用who/whom/that,可省略。

当先行词指物,定语从句中差宾语时用which/that,可省略。

The man (who/whom/that) he wanted to see last week is in Shanghai.This is the pen (which/that) my friend gave to me.先行词(人)+介词+whom 如:She is the girl with whom I went there.注意:先行词(物)+介词+which 如:This is the house in which I was born.3、当定语从句中名词前差定语时用whose,不可省略。

如:They rushed over to help the man whose car had broken down.Please pass me the book whose/of which cover is green.4、当先行词为时间名词,定语从句中差时间状语时用when/介词+which,不可省略。

如:I’ll never forget the day when/on which I met you.注意:当先行词为时间名词,定语从句中差宾语时用which/that,可省略。

如:The photo reminds me of the days (which/that) I spent in the countryside.5、当先行词为地点名词,定语从句中差地点状语时用where/介词+which,不可省略。

如:The building where/in which he lives is very old.注意:当先行词为地点名词,定语从句中差宾语时用which/that,可省略。

如:This is the building (which/that) we built last year.6、当先行词为原因名词,定语从句中差原因状语时用why/介词+which,不可省略。

如:Who can tell me the reason wh y /for which Tom wasn’t here today?注意:当先行词为原因名词,定语从句中差宾语时用which/that,可省略。

如:I won’t listen to any reason (which/that) you give me.7、当先行词为the way,定语从句中差方式状语时用in which/that/x。

如:We change the way (in which/that/x) we speak when talking with different people.8、that不能用于非限制性定语从句。

六、只能用that,不宜用which的情况:1、先行词是形容词最高级或者它的前面有形容词最高级时。

This is the best that has been used against air pollution(反对空气污染) in cities.English is the most difficult subject that you will learn during these years.2、先行词是序数词,或它的前面有一个序数词时。

The first thing that we should do is to help him.He is the last person that I want to see.3、主句中已有疑问词时。

Which is the bike that you lost?4、关系代词前有介词时。

The building in which he lives is very old.5、先行词既有人又有物时。

The bike and its rider that had run over (撞倒了)an old man were taken to the police station. 6、先行词是all, much, little, something, everything, anything, nothing, none, the one等代词时。

You should hand in all that you have.We haven’t got much that we can offer you.I mean the one that you talked about just now.7、先行词前面有only, any, few, little, no, all, one of, the same, the very等词修饰时。

The only thing that we can do is to give you some money.Li Ming is the only one that got full marks (满分)in our class.Li Ming is one of the students that want to be teachers in our class.8、有两个定语从句,其中一个关系代词已用which,另外一个宜用thatEdison built up a factory which produced things that had never been seen before.七、学好定语从句的诀窍:学会划分句子成分。
