(word完整版)高中定语从句讲解与练习

定语从句专项讲解与练习1、定语从句在句中修饰某个名词或代词，被定语从句修饰的词叫先行词。

定语从句需用下列关联词：关系代词和关系副词。

它们起连词作用，本身做从句的主语、宾语、表语或定语，本身在从句中作时间、地点或原因状语。

主要有who, whom, that, whose, which, as, when, where, why。

PS:what 不能引导定语从句. 指人的关系代词有who、whose、whom、that. 指物的关系代词有which、whose(=of which)、that.The old man who/whom /that we visited yesterday is a famous artist.Miss Wang is taking care of the child whose parents have gone to Beijing .The man with whom my father shook hands just now is our headmaster. （=The man who/whom/ that my father shook hands with just now is our headmaster.）I like the books which / that were written by Lu Xun.The desks (which/that) we made last year were very good.This is the house in which we lived last year. (= This is the house which /that we lived in last year.)I live in the room whose windows face south. (= I live in the room ,the windows of which face south.)2、掌握以上关系代词、关系副词的含义及使用时，要特别注意以下几点：1）指人时宜用who 的情况：a. 当先行词是one, ones, anyone 或those , these 时，关系代词用who。

The comrade I want to learn from is the one who studies hard and works hard. Anyone who breaks the law should be punished.Anyone who goes there will be punished.These who are going to Beijing are the best students of our school.b. 在there be 开头的句子中。

There’s a beautiful girl who came to see you this morning.There is a student who wants to see you.c. 先行词后有一个较长的定语。

I met a foreigner in the city last week who could speak Chinese well.d. 一个句子中带有两个定语从句，其中一个定语从句的关系代词是that，另一个宜用who，以免重复。

The student that won the first prize is the monitor who works hards.e. 在非限定性定语从句中。

She has a brother, who worked at that factory ten years ago.2) 指物时宜用that 的情况：a. 当先行词为all, none, much, little, few, something, anything, everything, nothing 等不定代词时。

All that can be done has been done.b. 当先行词既指人又指物时。

He spoke of the men and the thing (that) he had seen abroad.c. 当先行词是疑问词who, what, which 时或者句子以疑问词who , what , which 打头时。

Who that has such a home doesn’t love it?d. 先行词是序数词、形容词最高级或者当先行词被序数词或形容词的最高级修饰时。

This is one of the best films that I have ever seen.This is the best that can be done now.e. 当先行词被the very, the only, the last, the same , just, one of , any, every , few , little , no , all , one of 等修饰时。

This is one of the very book that I am looking for.f. 关系代词在从句中作表语。

Mary is no longer the girl that she used to be.3) 只能用which 不能用that 的情况。

a. 引导非限定性定语从句修饰某物或整个句子。

Bruce went towards the fire, which was still smoking.Tom came back late, which made his parents very angry.b. 关系代词作介词的宾语。

This is the house in which Lu Xun once lived.c. that，those作主语时Those which are on the desk are English books.4) 关系代词as 和which都能引导非限定性定语从句代表整个句子的内容，as 引导的从句可位于句首或句末，which引导的定语从句则不能位于句首。

Which you know, he is a good man. (×)As you know, he is a good man. (√)5)关系副词when, where, why其含义相当于on which, in which , for which等，可以互换：The day when /on which I met him first was May 1st.I don’t know the reason why /for which he didn’t come.6)whose指物时，可以与of which等结构互换，但应注意与冠词的位置关系：This is the book the cover of which / of which the cover / whose cover is blue. 7)有时可用that代替关系副词。

在口语中常省略。

This is the reason (why / for which / that) he came late.8)先行词是专有名词、整个句子或世界上独一无二的物质名词时，一般用非限定性定语从句修饰。

The sun, which gives us light and heat, is very big.9)在先行词和定语从句之间有无逗号有时会引起名义的变化：He said nothing that made her angry. 他没说使她生气的话。

He said nothing, which made her angry. 他一言不发，这使她很生气。

10)部分短语动词中的介词不可与动词拆开，在定语从句中其介词不可前置，只能放在其动词之后。

Is this the book which she is looking for?The old man who/whom they are waiting for is Professor Li.The child who/whom she is looking after is W ang Ping’s son.11) 先行词前有such、the same、as时, 关系代词用as，不用that, 但the same…as…表示同样的, the same…that…表示同一的。

He knows as many people as are present at the meeting.Such people as you refer to are rare nowadays.3、定语从句与强调结构It is the place where they lived before.It is in the place that they lived before.第一个句子为定语从句，where指代the place，在定语从句中作状语，第二个句子为强调结构，强调in the place, that没有意义，把放回后面句子，句子意思完整。

Where is it that he found the lost watch? (强调句型，强调疑问副词where.) Where is the watch he found yesterday? (定语从句，that指代the watch.)4、定语从句中的先行词Is this book the one that you bought yesterday?Is this the book that you bought yesterday?第一个句子中，this book是主句的主语，the one是先行词。

在第二个句子中this是主句的主语，the book是先行词。

一定要避免出现：Is this book that you bought yesterday?5、定语从句与同位语从句定语从句相当于形容词，它对先行词起修饰、描述或限制作用，而同位语从句则相当于名词，对其前面的词给予说明或作进一步解释，即说明该词所表示的具体内容。

例如：The news that we heard is not true. (定语从句)The news that he won the prize is not true. （同位语从句）另: 在“have no idea ＋从句”结构中，其从句都作idea的同位语。

例如：I have no idea when she will be back.6. 限制性定语从句与非限制性定语从句的区别：All the students who study hard have passed.学习努力的学生都考试及格了。
