定语从句(I)关系代词的用法定义—复合句中修饰名词或代词的从句基本用法：1. who 指人，在从句中作主语、宾语、表语2. whom指人，在从句中作宾语3. whose 指人或物，在从句中作定语4. which 指物，在从句中作主语、宾语、表语5. that 指人或物，在从句中作主语、宾语、表语一、定语从句的定义与关系词的分类1.在复合句中，修饰某一名词或代词的从句叫定语从句。
引导定语从句的词叫关系词，被修饰的名词或代词叫先行词。
2. 关系词分为关系代词(that, which, who, whom,whose, as等)和关系副词(when, where, why 等)两类。
主句关系主语代词Beijing, which is the capital of China is a very beautiful city.先行词定语从句主句中的表语中国的首都北京是一座非常美丽的城市。
二、关系代词的基本用法1. who 指人，在定语从句中可以作主语、宾语或表语，作宾语时可省略The children who were injured in a car accident are being treated in the hospital now.在车祸中受伤的孩子们现在正在医院接受治疗。

定语从句是我们初中学过的一项语法，上面这些句子与你初中学的有差别吗？是不是有点不同呢？从这个单元开始，我们将学习定语从句的升级版，但还是从头开始学哟。
语法点拨【定语从句一P1】，定语从句的定义Do you know the girl who came here yesterday? 你认识昨天来的那个女孩吗？The book which he bought the day before yesterday is very good.他前天买的那本书很棒。
He is the man whom we should learn from. 他就是我们应该学习的人。

其中粗体的部分就是定语从句，划横线的部分叫做先行词，也就是被定语从句修饰的词。
定语从句：修饰一个名词或代词的从句称为定语从句，一般紧跟在它所修饰的先行词后面。
先行词：被定语从句修饰的名词或代词。
关系词：上面例子中的关系代词who, whom, which, that是用来引导定语从句的连接词。
这些连接词代替先行词在从句中担任一个成分，如主语、宾语或表语。
例如：Those students who study in this school are good at football.（who代替先行词students在从句中充当主语）There is still much homework which we must finish.（which代替先行词homework在从句中充当宾语）关系代词引导的定语从句I. who和whom1. who和whom代表人, 当先行词在从句中作主语时用who引导，作宾语时用whom引导。
