定语从句的三要素口诀定语从句，哎呀，听起来有点复杂，其实它并不难掌握哦。

只要你记住三个要素，就能轻松搞定。

那这三个要素是什么呢？快跟我一起来看看吧！1. 定语从句的基本概念1.1 定义定语从句就是用来修饰名词的从句，简单来说，就是给名词“加点料”。

就像你做菜时加点调料一样，它让句子更加丰富、具体。

比如，“The book that I bought yesterday is interesting.” 这句中的“that I bought yesterday”就是定语从句，它给“book”加了个特别的描述。

1.2 功能定语从句的主要功能就是对名词进行详细说明。

就像你介绍朋友时，不仅说他们的名字，还会提到他们的特点一样。

通过定语从句，你可以让听者对名词有更清楚的了解。

2. 定语从句的三要素要搞定定语从句，你得抓住三个关键点。

听好了，这可是核心要素哦！2.1 关系词关系词就是把定语从句和主句连接起来的“桥梁”。

常见的关系词有“who”、“which”、“that”等。

比如，“The girl who is singing is my sister.” 这里的“who”就是关系词，它把“is singing”这个信息传递给“girl”。

2.2 先行词先行词是定语从句修饰的对象，简单来说，就是“定语从句要给谁加料”。

比如在句子“The car that I want to buy is too expensive.”中，“car”就是先行词。

你可以理解为，定语从句是为了给先行词提供更多信息。

2.3 定语从句的内容内容部分就是定语从句的核心，包含了关于先行词的具体信息。

这部分描述了先行词的特征或动作，比如“who is singing”就是对“girl”的详细描述。

这是定语从句的“主菜”，要把重点放在这部分哦！3. 例子分析好了，现在我们来看看一些例子，把理论变成实际操作，确保你能掌握得更牢靠！3.1 短句子练习1. “I have a friend who lives in New York.”关系词：who先行词：friend内容：lives in New York。

定语从句巧记口诀1.定从分类有奥妙, 限与非限看逗号;定前必有先行词，名代两类最适宜；定从先行很紧密，代副两词拉关系；2.关系代词有六个，听我逐一来说破；which表物人用who,人物都有that顾；which用在逗号后，意表前句你要know;who做主语很称职，whom用到宾语里；3.that用法真有趣，两个地方它不去；逗号后边它不去，介词之后不考虑；4.That which代表物，区别听我来叙述；先行若是不定代，that就把which 踹；先行词前有两数，就用that定无误；先行词前最高级，还用that必无疑；句中若有there be, that应把which替；先行主中做表语，避免重复从句里；（Just the only very same last, 其后也要用that;）5.指人可用that who, 以下情况多用who;Those people做先行，There be的结构中；先行指人不定代，从中做主who要在；两个定从一起来，不要重复你有才；6.定从之中少定语，whose为你唱一曲；Whose指人又指物，所属关系要记住。

7.As/which在句末，若有否定as错；句首只能用as,还有认知猜想词；固定结构用as, the same /such/so/as;So /such …that宾不离，so/such…as宾要弃；8.关系代词到这里，主宾表定作用起；关系代词做宾语，省与不省全靠你；9.关系副词when/where/why, 从中做状莫懈怠；时间用when原因why,地点where经常在；关系副词可替换，介词加上关系代；关系代，关系代，that与who要除外；挑选介词要聪明，必看动词和先行；聪明反被聪明误，只因乱用关系副；关系副，关系副，定缺主宾它不住；它不住，它不住，关系代词来玩酷；10.只记上边不可以，特殊情况告诉你；先行用way 做状语, in which/ that /略可以；one of +复做先行，从中谓语复数明，one前若有only/very, 从中谓语定用单；定从名从可转换，all that被what换；定语从句巧记口诀分段解析：1. 定从分类有奥妙, 限与非限看逗号;定语从句分为两大类：限制性定语从句和非限制性定语从句，区分它们有两个标准：1）从内容上看，限制性定语从句与它所修饰的先行词关系紧密，不可去掉，去掉后意思就不完整了；非限制性定语从句只对先行词起补充说明的作用，去掉后不影响句子的完整性。

一、定语从句的定义和作用1.1 定语从句是修饰名词或代词的句子，用来对其进行进一步的说明和限定。

1.2 定语从句通常由关系代词(如which, that, who, whom, whose)引导。

二、which 和 that 的用法2.1 which 和 that 都可以用来引导非限制性定语从句。

例如：The book, which/that is on the table, belongs to me.2.2 which 和 that 都可以用来引导限制性定语从句，但在口语中通常只用 that。

例如：The book that/which is on the table belongs to me.三、which 和 that 的区别3.1 用法上的区别：3.1.1 which 在非限制性定语从句中的常用形式为“，which + 句子”，而 that 通常只用在限制性定语从句中。

例如：The book, which was published in 2001, is very popular. (非限制性定语从句)The book that was published in 2001 is very popular. (限制性定语从句)3.1.2 which 用在以介词开头的非限制性定语从句中时，不能被省略，而 that 可以。

例如：The house in which I live is very old. (介词+which的非限制性定语从句)The house that I live in is very old. (以介词开头的限制性定语从句)四、which 和 that 的语法特点4.1 which 和 that 都可以用在表示物的名词前的定语从句中。

4.2 which 和 that 都可以用在表示人的名词前的定语从句中。

例如：The man who/whom/that we met yesterday is a doctor.4.3 which 和 that 在从句中所起的作用是主语、宾语、或表语时，其用法是一样的。
