高中定语从句讲解与练习（附答案）
高中定语从句讲解与练习（附答案）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。
高考英语定语从句讲解+习题-
在复合句中充当定语的从句叫定语从句。
定语从句的作用相当于形容词，用来修饰主句中的某一名词或代词或整个主句，所以，也称作形容词性从句。
被定语从句修饰的词叫先行词，定语从句一般紧跟在它所修饰的先行词之后。
在先行词和定语从句之间起连接作用的词叫关系词。
关系词有关系代词和关系副词两种。
提示：关系词在定语从句中有三大作用1. 连接作用——连接先行词和定语从句。
I I . 我把我所有的钱都给了她。
（连接先特词和定语从句I ）2. 替代作用——在定语从句中替代从句所修饰的先行词。
a . 住在隔壁的那个人是个名师。
（替代）3. 成分作用——在定语从句中作主语、宾语、定语或状语。
I . 我喜欢传统的中国画。
（在定语从句中作主语）一、关系代词引导的定语从句引导定语从句的关系代词主要有, , , , 等。
它们分别代替前面的先行词，并在定语从句中作主语、宾语或定语。
A．指人，在定语从句中作主语。
借钱给你的那人叫什么名字？（定语从句修饰先行词）. 谁笑到最后谁笑得最好。
（定语从句修饰先行词）会议主席坐在我右边，他先发言。
（定语从句修饰先行词）B．指人，在定语从句中做宾语。
在口语或非正式文体中，可省略或可用来代替，但在介词后面以与在非限制性定语从句中只能用。
有些人我们是喜欢的，有些人则是我们讨厌的。
（定语从句分别修饰先行词, ）I .和我一起工作的人都很友好。
（定语从句修饰先行词）. , I , .. , I , .昨晚我在里和卡特先生交谈过，他对我们的计划很感兴趣。
（非限制性定语从句中不能用代替）, I , .两个人来到我的办公室，我以前从未见过他们。
（在介词后面不用）C．人、物皆可，做定语，后面要紧跟被修饰的名词，先行词和后面的名词之间往往是从属关系。
有些人，他们的脸你永远难以忘怀。
（定语从句修饰先行词）I .我看见一些树的树叶由于空气污染而发黑。
（定语从句修饰行词）D．1．指物，在定语从句中做主语或宾语。
做宾语时常可省略。
高中英语定语从句讲解及练习
高中英语定语从句讲解及练习定语从句是高中重点知识，也是高考常考点，大家也不容易掌握，这篇文章主要教你关系代词引导的定语从句关系副词引导的定语从句判断关系代词与关系副词限制性和非限制性定语从句等内容，有例题讲解定语从句在句中做定语，修饰一个名词或代词，被修饰的名词词组或代词即先行词。
定语从句通常出现在先行词之后，由关系词（关系代词或关系副词）引出。
关系代词有：who, whom, whose, that, which等。
关系副词有：when, where, why等。
18.1 关系代词引导的定语从句关系代词所代替的先行词是人或物的名词或代词，并在句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主语时，从句谓语动词的人称和数要和先行词保持一致。
1）who, whom, that 这些词代替的先行词是人的名词或代词，在从句中作主语和宾语。
例如：Is he the man who/that wants to see you? 他就是你想见的人吗？（who/that在从句中作主语）He is the man whom/ that I saw yesterday. 他就是我昨天见的那个人。
（whom/that在从句中作宾语）2）whose 用来指人或物，（只用作定语, 若指物，它还可以同of which互换）。
例如：They rushed over to help the man whose car had broken down.那人车坏了，大家都跑过去帮忙。
Please pass me the book whose （of which）cover is green.请递给我那本绿皮的书。
3）which, that所代替的先行词是事物的名词或代词，在从句中可作主语、宾语等。
例如：A prosperity which / that had never been seen before appears in the countryside.农村出现了前所未有的繁荣。
高中英语定语从句语法精讲练习(带答案)
高中英语语法讲解——定语从句(名师精讲必考语法知识点+实战训练，建议下载练习)一、先行词、关系代词和关系副词1．先行词(antecedent)就是被定语从句所修饰的名词。
在英语中，定语从句跟在被修饰词之后，所以被修饰词就是“先行”的词。
eg. The lovely girl often helps the old lady.She lives next door to our school.→The lovely girl who lives next door to our school often helps the old lady.→The lovely girl often helps the old lady who lives next door to our school.The lovely girl often helps the old lady.You met her at school yesterday.→The lovely girl (whom)you met at school yesterday often helps the old lady.→The lovely girl often helps the old lady (whom) you met at school yesterday.2．连接定语从句，要用关系代词(relative pronoun)和关系副词(relative adverb)。
关系代词和关系副词与连接词不完全相同，因为它们除了连接主句和定语从句，还在定语从句中代替一定的成分。
eg. The book which I bought yesterday is very interesting.← The book is very interesting. I bought the book yesterday.I have visited the house where Andersen wrote The Emperor’s New Clothes.←I have visited the house. Andersen wrote The Emperor’s New C lothes in the house.二、关系代词1．who的先行词是“人”，在从句中代替主语。

定语从句与高考定语从句是高考的热点，主要考查关系代词和关系副词的正确运用，特别是它们在非限制性定语从句中的运用。
主要考点有：1.关系代词who, which, that, whom, as, whose的基本用法。
2.关系副词when, where, why的基本用法。
3.定语从句中关系词的特殊用法。
4.定语从句中“介词＋关系代词”介词的确定。
5. which/ as引导的非限制性定语从句的区别。
一、定语从句的分类限制性定语从句定语从句非限制性定语从句二、限制性定语从句和非限制性定语从句的区别区别一：形式不同限定性定语从句主句和从句之间不用逗号隔开；而非限定性定语从句与主句之间通常____用___逗号隔开。
区别二：功能不同限定性定语从句用于对先行词的意义进行修饰、限制和识别，如果去掉，就会造成句意____不明确___；而非限定性定语从句用于对先行词起补充说明作用，如果省略，句意不影响。
如：People who take physical exercise live longer. 进行体育锻炼的人活得长些。
(若把从句去掉句子就失去意义)His daughter, who is in Boston now, is coming home next week. 他女儿现在在波士顿，下星期回来。
(若把从句去句子意义仍然完整)比较下面的两个句子：I have a sister who is a doctor. 我有一个当医生的姐姐。
(姐姐不止一个)I have a sister, who is a doctor. 我有一个姐姐，她是当医生的。
(只有一个姐姐)区别三：翻译不同在翻译定语从句时，一般把限定性定语从句翻译在它所修饰的先行词之前，而把非限定性定语从句与主句分开。
如：He is the man whose car was stolen. 他就是汽车被窃的那个人。
I’ve invited Jim, who lives in the next flat. 我邀请了吉姆，他就住在隔壁。
