定语从句详解及练习附答案第一部分:基础知识（一）．定语从句概述定语可以由形容词，代词，数词,名词，不定式,介词短语来充当。
如果是一个句子担任定语，那么这个句子就叫做定语从句,又可称为形容词性从句。
定语从句通常修饰某一名词或代词，被定语从句修饰的这一名词或代词叫先行词，它位于定语从句之前，定语从句在先行词后面，应尽量紧跟先行词。
定语从句的作用即在于对先行词进行限定说明或补充说明。
(二）．定语从句的引导词.定语从句的引导词分为两类，关系代词（that, which, who, whom, whose ）和关系副词( when, where，why ），引导词在先行词和定语从句之间，既起连接作用，即连接先行词和定语从句，更重要的是,它又在定语从句中作一个成分。
（三）．关系代词1。
that 指人，物，在从句中作主语，宾语，表语.This is the photo that I took in the country.He is the singer that I met yesterday。
2。
which 指物，在从句中作主语,宾语，在非限定定语从句中充当定语，或者代替前句The film which we saw last night was moving.3. who 指人，在从句中作主语,宾语。

The man who you just talked to is Tom。

定语从句练习题附答案解析1．Han Yan is the only student ________ gets a chance to take part in the final drawing match.A．that B．which C．when D．whose【答案】A【解析】【详解】句意：韩燕是唯一一个有机会参加绘画比赛决赛的学生。
考查定语从句关系词。
that先行词指人或物；which先行词指物；when先行词指时间；whose先行词既可指人也可指物。
根据题干中“the only student”可知题中先行词有the only修饰，且在从句中作主语，关系代词只能用that。
故选A。

——是的，他正在搜索他文章所需的信息。
考查定语从句。
根据英语语法，whether和what不可以引导定语从句，B、C选项可排除。
根据句子结构，定语从句的先行词information指物，关系代词who 指人，D选项可排除，故选A。
【点睛】关系代词that既可以指人也可以指物，在从句中作主语、宾语或表语；关系代词who指人，在定语从句中做主语，作宾语时应用whom。
此处先行词information指物，且关系代词在定语从句中作宾语，故应用关系代词that。

定语从句的用法定语从句在英语阅读材料里处处可见。
它是初中阶段的重要语法内容，也是学好英语的难点。
我们先来了解一下定语：一本有趣的书an interesting book形容词interesting做定语修饰名词book一位漂亮的女孩a beautiful girl形容词beautiful做定语修饰名词girl定语就是在句子中修饰名词或代词的词。
我们还可以说成：a book that is interestingthat is interesting这个句子做定语修饰名词booka girl who is beautifulwho is beautiful这个句子做定语修饰名词girlinteresting 和that is interesting作用是相同的,都是用作定语来修饰名词book.一、定语从句的概念在复合句中,修饰某一名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词,定语从句一般放在先行词的后面。
要区分复合句中的主句和从句，下面每个句子中的黑体字部分都为主句，注意体会。
二、定语从句的关系词引导定语从句的关系词有关系代词和关系副词,常见的关系代词包括that, which, who，宾格whom,所有格whose,关系副词包括where, when, why。
关系代词和关系副词放在先行词及定语从句之间起连接作用,同时又作定语从句的重要成分。
注: 关系代词在句中充当主语、宾语，因此定语从句中不能再出现关系代词所替代的名词或代词。
三、定语从句的分类根据定语从句与先行词的关系,定语从句可分为限制性定语从句及非限制性定语从句。
限制性定语从句紧跟先行词,主句与从句不用逗号分开,从句不可省去。
非限制性定语从句，主句与从句之间有逗号分开,起补充说明作用,如省去,意思仍完整。
He helped me when I was in trouble, which made me very moved.(非限制性定语从句,which 指代前面整个句子)四、关系代词的用法1.（1）that 既可以用于指人,也可以用于指物。
