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 person who visited our classroom yesterday was our new headmaster。
The man who you just talked to is Tom。
4。
whom 指人，在从句中作宾语。
That is the professor whom you want to know。
5. whose 指人，物，在从句中作定语,相当于先行词+ ’s，后接一名词.I know the boy whose parents are dead。
I don’t like those cities whose roads are dirty.注:关系代词在从句中作宾语时可以省略。

初中英语语法梳理和提高---定语从句总结与精讲（含答案）定语从句在复合句中，修饰某一名词或代词的从句叫做定语从句。
知识梳理：提纲挈领，抓住重点和难点！定语从句所修饰的词叫先行词。
定语从句放在先行词后面。
定语从句分为限定性定语从句和非限定性定语从句。
本章只介绍限定性定语从句。
引导定语从句的词有关系代词that、which、who、which、whose和关系副词where 、when，关系代词和关系副词是引导词，在定语从句中担当某一成份。
关系代词和关系副词的作用：先行词指物时，关系代词用that 或which（在句中作主语或宾语）。
如：China is a country which / that has a large population.The computer game which/ that he is playing is his favorite.先行词指人时，关系代词用（who）作主语或宾语，whom (作宾语)，whose (作定语)，that (作主语或宾语)。
如：The man who is mending the machine has been retired.This is the policeman who/ whom t hey were talking about yesterday.I like the girl whose mother is an actor.注意：下列情况下关系代词只用that 而不用which 或who。
先行词是指物的不代词，如：all, little, few, much, none, anything, nothing, everything等时。
如：I didn’t understand t he words all that he said.2．先行词由最高级、序数词以及any, very, only, all, no, just 等所修饰。
初中英语语法——定语从句用法总结归纳定语从句是一种引导句，用来修饰主句中的其中一元素，它可以放在
句子的末尾也可以放在句子的中间，它可以表示人或物的属性、行为，也
可以表示特定的时间、地点，其可以紧挨主语或主句元素。
关于定语从句
用法，可以总结如下：
一、定语从句的关系词
1. 一般情况下，用that 或which来引导定语从句。
2. 当定语从句修饰人的时候，用who或whom来代替that或which。
二、定语从句的排列方式
1.无论是放在句首、句中还是句末，定语从句的顺序是：关系词+主
语+谓语+其他成分。
2.在句尾，定语从句可以省略关系词，但同时必须有清楚的上下文逻
辑关系，以保证语意的正确表达。
三、定语从句使用的特殊情况
1. 当定语从句改变主句的主语时，要使用as 引导定语从句。
2. 当定语从句修饰不明确的物体时，可以用whatever, whichever, who或whom来引导定语从句。
3. 当定语从句的内容被省略时，可以用all, some, any, none, little, few, much, many等来引导定语从句。

定语从句一、考点解读我们主要复习如下内容：1．先行词与关系词2．限制性定语从句与非限制性定语从句3．关系代词的用法4．关系副词的用法5．定语从句需注意的事项6．初中阶段学习定语从句的要点二、专题梳理（一）什么是定语从句定语可以由形容词、名词、代词、数词、分词、副词、不定式以及介词短语等来充当，也可以由一个句子来充当。
充当定语功能的句子称为定语从句。
定语从句在句中的作用相当于形容词，故又称为形容词性从句。
定语从句用来修饰名词、代词或整个主句。
e.g.Tom is a hardworking student who always gets first in his class.汤姆是一个用功的学生，他在班里总是第一名。
（修饰名词student。
）Football is played over 80 countries, which makes it popular.80多个国家都在踢足球，因此足球很流行。
（修饰整个主句Football is played over 80 countries。
）（二）先行词与关系词1．什么是先行词：被定语从句修饰的名词、代词称为先行词。
可以这样理解，之所以称它为先行词，是因为先行词总是出现在定语从句之前，而不同于普通形容词修饰名词，形容词常位于名词之前。
e.g.Don’t forget the book that I told you to bring.别忘了我让你带的书。
（the book为先行词。
）2．先行词与关系词的关系：引导定语从句的词被称为关系词。
关系词根据其在定语从句中的功能可分为关系代词和关系副词。
关系代词在定语从句中作主语、宾语、表语、定语等，关系副词在定语从句中作状语。
含有定语从句的句子一般分为两层：即主句层（第一层），定语从句层（第二层）。
特别提示：①关系词一般紧跟在先行词之后引导定语从句。
定语从句总在被修饰的先行词后面。
②在定语从句中，关系代词起着代词和连词的作用，关系副词起着副词和连词的作用。

初中定语从句全解（含真题答案和解析）关于定语从句的考点分析其实之前已经给大家讲过。
今天，小简老师又添加了一些更细的内容，比如关系代词只能用that的情况等，并且将40道历年真题及其答案解析直接附在考点讲解后面，便于同学们学习/复习并巩固。
定语从句没有想象中难，一起来学吧！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，引导定语从句的词叫关系词，定语从句一般放在先行词的后面。
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）等，关系副词包括where， when， why等。
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。
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。
非限制性定语从句与主句之间有逗号分开，起补充说明作用，如省去，意思仍完整。
四、关系代词的用法1. that 既可以用于指人，也可以用于指物。
在从句中作主语、宾语或表语。
作主语时不可省略，作宾语可省略。
例如：Mary likes music that is quiet and gentle.玛丽喜欢轻柔的音乐。
（that作主语）The coat （that） I put on the desk is blue.我放在桌子上的那件外套是蓝色的。
（that作宾语）2.which用于指物，在句中作主语、宾语或表语。
作主语不可省略，作宾语可省略。
例如：The building which stands near the train station is a supermarket.位于火车站附近的那座大楼是一家超市。
（作主语）The film （which） we saw last night was wonderful.我们昨天晚上看的那部电影很好看。

2．B解析：B【解析】【详解】句意：瑞安广场后面有个图书馆，里面有很多书。
我们经常喜欢读书。
考查意义一致。
A. a museum that is open in the day time白天开放的一个博物馆；B. a library that has a lot of books有许多书的一家图书馆；C. a market which sells delicious fruit出售美味水果的一家市场；D. a restaurant which will be built in 2 years两年以后将会建成的一家饭店。
根据We often enjoy reading books.可知，我们经常在那里读书，所以那是一个图书馆，里面有好多书。
故选B。
3．B解析：B【解析】【详解】句意：——你认识和我们老师说话的那个人吗？——哦，他是托尼的父亲。
which哪个；who谁；whose谁的；what什么。
根据 is talking with our teacher作the man 的定语，先行词man是人物，连接词在从句中作主语，所以用连接词who或者that，结合选项，故选B。
【点睛】定语从句用来充当句中定语的成分，被修饰的名词叫先行词，连接主从句的是关系词。
关系词分：1关系代词：who , whom , whose , which , that 。
2 关系副词：where,when why 等。
一般的who 用于指代人的先行词，which 用来指代物的先行词，that既可指人又可指物．关系代词在从句中作主语、宾语。
作宾语时可以省略，作主语时不可以省略。
解析：A【解析】【详解】句意：Lily 不知道她和她的朋友们能做些什么，来帮助那个父母为了钱离开家乡的小男孩。
考查宾语从句和定语从句。
A. what什么；whose谁的；B. how如何；who谁；C. how如何； whose谁的。
根据she and her friends can do可知，此处do后面缺宾语，即“做的事情”，所以第一空用what；根据parents have left their hometown for making money是boy的后置定语，是对boy的进一步解释说明，且parents和boy之间是“所属”关系，所以第二空用whose。
