定语从句语法详解(最新整理)
1. 限定性定语从句：限制性定语从句是先行词在意义上不可缺少的定语，如果去 掉，主句的意思就不完整或者失去意义。从句和主句的关系 十分密切，不可用逗号隔开，也不可省略。
eg She has found the necklace that she lost two weeks ago. That 代替先行词 necklace，在从句中充当 lost 的宾语 The man who spoke last was Dr Li. Who 代替先行词 man 在从句中充当主语
That，which 可互换，下列情况勿照办 That 情况比较多，先来对你说一说 不定代词这一伙，全用 that 准没错 先行词前有修饰，千万不要用 which 要用 which 别着急，介词提前逗隔离
五．介词+which/whom 结构用法
介词 + which 物 whom 人
1. “介词+关系代词”引导定从时，介词的宾语只能用 which 或 whom 介词+which 在定从作时间，地点，原因状语，相当于 when，where，why。 She still remembers the day on which （when）she won the prize。 Potatoes can be grown in places in which (where)it is too cold to grow rice. 有些地方太冷不能种水稻，但可以种马铃薯。 This is the reason why he came late。 This is the reason for which he came late。

定语从句超详细讲解什么是定语从句定语从句是一种修饰名词或代词的从句，用来对所修饰的名词或代词进行进一步的说明或限制。
定语从句通常由关系词引导，在句中充当修饰成分。
关系词的种类常见的关系词有：who, whom, whose, which, that。
关系词根据在从句中的作用，可分为主格关系词、宾格关系词和属格关系词。
- 主格关系词：who, which- 宾格关系词：whom, which- 属格关系词：whose, of which定语从句结构定语从句的基本结构为：关系词 + 主语 + 谓语 + 其他成分。
根据所修饰的名词在定语从句中的作用，可分为三种结构：1. 主语关系从句：关系词在从句中作主语，修饰前面的名词。
- 例：The book which is on the table is mine.（在桌子上的那本书是我的。
）2. 宾语关系从句：关系词在从句中作宾语，修饰前面的名词。

- 关系词在从句中可省略，但要根据上下文的需要决定是否省略。

完整版)定语从句详解+例句定语从句是修饰名词或代词的从句。
也就是说，名词或代词后面的从句就是定语从句，而被定语从句修饰的名词、代词、甚至词组或句子叫做先行词。
引导定语从句的词叫做关系词，其中包括关系代词和关系副词。

关系副词有when（先行词为时间）、where（先行词为地点）和why （先行词为原因），它们是介词和which/whom的组合。
定语从句分为限制性和非限制性两种。
当先行词与关系词之间没有逗号隔开时，就是限制性定语从句；而当先行词与关系词之间有逗号隔开时，就是非限制性定语从句，而且一般由which引导。
唯一可以置于先行词之前的定语从句由关系代词as引导。

谓语动词则是指定语从句中的主干动词，宾语则是指谓语动词所接受的动作对象。
其他成分则包括状语、补足语等，用于修饰谓语动词或补充说明整个句子的意义。
