几个概念
1. 定语从句 担任定语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， 所以又称为形容词性从句。 e.g. ※ The boy whose father is a doctor studies very hard. ※ This is the best book that I have ever read. 2. 先行词 被定语从句修饰的名词、代词称为 先行词。先行词的名称的来源可以理解为：先 行词总是出现在定语从句之前。
小 结
关系词 that who whom 作 用 主语， 宾语， 表语 先行词 例句 Do you know the girl who/that has got an A in the exam? She got a computer which/that her parents bought for her.
请你分别分析出以下定语从句 的关系词、从句部分、先行词。
1. The English-Chinese dictionary which/that my father bought for me many years ago is still of great value. 2. I hate the people who talk much but do little.
2. 关系词 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 以分为关系代词 (that,who,whom,which,whose)和关系副词 (when,wherer,why)。关系代词在定语从句 中做主语、宾语、表语、定语等，关系副 词在宾语从句中做状语。 e.g. ※ A doctor is a person who looks after people’s health. ※ This is a factory where my father works.

作用使句子表达更具体、生动，有助于读者或听者更准确地理解所表达的内容。
前置定语通常将定语从句放在被修饰词的前面，如“漂亮的花园”中，“漂亮的”就是前置定语。
将定语从句放在被修饰词的后面，用逗号隔开，如“花园，漂亮的”中，“漂亮的”就是后置定语。
对被修饰词进行必要的限定，使句子意思更明确，如“我喜欢那本红色的书”中，“红色的”就是限定性定语从句。
对被修饰词进行补充说明，去掉后不影响句子意思的完整性，如“我昨天买了本书，它是关于历史的”中，“它是关于历史的”就是非限定性定语从句。
后置定语限定性定语从句非限定性定语从句结构形式与其他从句区别与名词性从句区别名词性从句在句子中充当主语、宾语等成分，而定语从句则充当定语成分，修饰名词或代词。
与状语从句区别状语从句表达主句动作发生的时间、条件、原因等背景信息，而定语从句则对名词或代词进行修饰、限定。
与同位语从句区别同位语从句对前面的名词进行解释说明，两者处于同等地位；而定语从句则对前面的名词进行修饰、限定，处于从属地位。

今天的话题就是定语从句，即一个句子放在一个词的后面修饰 该词，这个句子就叫定语从句。 学习定语从句需要牢牢把握三点：
第一，定语从句和被修饰词之间要有一个连接词连接，该词
在语法上被称之为“关系代词或副词”；
第二，被定语从句修饰的词语，在语法上被称之“先行
词”，该“先行词”的作用是：在后面的定语从句中充当某
以下情况只能用“that”作关系代词：
1.先行词既有指人又有指物； 2.当先行词前有序数词或形容词最高级 时或有the only, the very等修饰时； 3.先行词是all, much, anything, something, nothing等不定代词； 4.主句是以who/which开头的特殊疑问句 时；
