高中英语定语从句(限制性、非限制性定语从句)
高中英语定语从句详解限制性定语从句非限制性定语从句限制性定语从句：Ⅰ. 概念：(1) 定语从句：在主从复合句中用作定语的从句叫定语从句。
定语从句一般紧接在先行词(antecedent)后面。
(2) 先行词：被定语从句修饰的成份。
先行词可以为一个词，短语，或整个主句。
(3) 引导定语从句的词叫关系词，分为关系代词和关系副词。
一、关系代词:关系词的作用：1) 引导定语从句，连接主句和从句，相当于一个连词；2) 必在从句中作某个句子成份（可以做主语，宾语，表语，定语，状语）常用的关系代词: that、which、who、whom、whose、as常用的关系副词（在从句中只作状语）: when、why、whereThe student who answered the question was John.The boy (whom) you are talking to is my brother.定语从句三步：第一找出先行词；第二看先行词在定语从句中的语法功能（做主语、宾语或状语）；第三选择合适的关系词。
Ⅱ. 几个关系代词的基本用法：●that: 可指人或物；在定语从句中作主语，宾语，表语。
(指人时，相当于who 或whom；指物时，相当于which)(一般不用于非限制性定语从句; 不可置于介词后作宾语) 如：1. A letter that/which is written in pencil is difficult to read. (主语)2. Do you know the gentleman that/who spoke just now?3. You can take anything ( that) you like. （宾语）●which: 指物；在定语从句中作主语，宾语，表语，定语。
如：1. The book which/that was on the desk was bought by my father.（主语）2. The book (which/that) I bought yesterday is very interesting.（宾语）●who, whom, whose:who: 主格, 在从句中作主语，在口语或非正式用法中作宾语; 只可指人whom: 宾格，在从句中作宾语; 只可指人whose: 属格，在从句中作定语，可指人也可指物。

高考英语语法复习之限制性定语从句和非限制性定语讲义
高中英语语法复习之限制性定语从句和非限制性定语定义和用法在英语语法中，定语从句是用来修饰名词或代词的句子成分，通常分为限制性定语从句和非限制性定语从句两种。
限制性定语从句和非限制性定语从句是英语语法中两个重要的概念。
限制性定语从句是指用来修饰一个名词或代词的从句，这个从句在句子中充当定语的作用，对名词或代词起限定、说明的作用。
与之相反，非限制性定语从句通常用来进一步说明被修饰的名词或代词，起到补充说明的作用，它不能充当主语、宾语等成分，并且通常可以被省略。
限制性定语从句通常由that、which、who、whom、whose等引导词引导，也可以由as、when、where、why等引导词引导。
限制性定语从句通常与主句之间需要用逗号隔开，而且通常放在主句之后。
例如:The book, which I read last week, is really interesting.(限制性定语从句)The man, who is a doctor, can help you.(限制性定语从句)非限制性定语从句则没有这些限制，它可以充当主语、宾语、表语、定语等成分，并且通常可以被省略。
非限制性定语从句通常由that、which、who、whom、whose等引导词引导，也可以用as、when、where、why等引导词引导。
例如:The book, that I read last week, is really interesting.(非限制性定语从句)The man, who is a doctor, can help you.(非限制性定语从句)需要注意的是，非限制性定语从句和限制性定语从句在句子中的作用不同，因此需要根据具体情况来选择合适的定语从句类型。
限制性定语从句是先行词在定语从句中充当主语或宾语，对先行词起修饰和限制作用，二者缺一不可。
限制性定语从句和非限制性定语从句是英语语法中的两个重要概念。
