短语、从句作定语时则放在所修饰的词之后，作后置定语。
二、1.先行词的定义：被定语从句修饰的名词、代词称为先行词。
如“The man”、“The book”。
2.先行词的位置：先行词之后。
三、关系代词1.关系代词所代替的先行词是人或物的名词或代词，并在从句中充当主语、宾语、定语等成分。
关系代词在定语从句中作主词保持一致。

一般whom作为宾语。
关系代词在从句中作主语，宾语，表语，定语等，关系副词在从句中作地点状语（where）时间状语（when），原因状语（why）。
四、例句1.who, whom, that这些词代替指人，“whom”作宾语指人，“that”既可作主语又可作宾语（作宾语可以省略），可以指人也可以指物。

定语从句相关知识点总结
定语从句相关知识点总结一、定语从句的概念。
1. 在复合句中，修饰某一名词或代词的从句叫定语从句。
被修饰的名词或代词叫先行词，定语从句一般放在先行词的后面。
- 例如：I like the book which/that is very interesting. 其中“book”是先行词，“which/that is very interesting”是定语从句，用来修饰“book”。
二、关系代词的用法。
1. that.- 既可以指人也可以指物，在从句中作主语或宾语。
- 当先行词是all, much, little, something, everything, anything, nothing, none等不定代词时，关系代词用that。
- 例如：All that can be done has been done.（先行词是“All”，关系代词“that”在从句中作主语）- 当先行词被序数词或形容词最高级修饰时，关系代词用that。
- 例如：This is the best film that I have ever seen.（先行词“film”被最高级“the best”修饰，关系代词“that”在从句中作宾语，可省略）- 当先行词被the only, the very, the same等修饰时，关系代词用that。
- 例如：This is the very book that I want.（先行词“book”被“the very”修饰，关系代词“that”在从句中作宾语）2. which.- 指物，在从句中作主语或宾语。
- 例如：The book which/that is on the desk is mine.（“which/that”在从句中作主语）；I like the book which/that you lent me.（“which/that”在从句中作宾语）- 在非限制性定语从句（从句与主句之间用逗号隔开）中，只能用which，不能用that。

定语从句知识点归纳
定语从句知识点归纳一、定语从句的定义定语从句（Adjective Clause）又称定语性从句，是由关系代词和关系副词所引导的，修饰名词或代词的一个从句。
定语从句一般在句中充当定语，但也有某些句型会将它置于句首，起补充说明之用。
二、定语从句中引导词的分类定语从句引导词有关系代词（口语中称为“指示代词”）和关系副词。
1.关系代词：定语从句中常用的关系代词有：who，whom，whose，which，that。
（1）who，whom，that指人，作主语、宾语均可。
（2）whose指人，作定语，表示所有格或“某人的”。
（3）which指物，特指物；作主语、宾语或表语；不可指人。
定语从句的关系副词主要有where，when，why，以及how，且多放于句首。
关系副词where（地点）、when（时间）指一段日期和地点，why（原因）指原因；how（方式）指方式、程度、顺序等。
三、空位句式定语从句中只有关系词，且关系词前无先行词时，叫做空位句式。
关系词就是用来做定语从句补充说明和替换先行词，所以如果没有先行词，关系词就有空位，里面什么都没有。
这种句式得特别注意：关系代词只能用that，不能既用which又用that，也对关系副词没有特别要求。
四、定语从句的用法及归纳定语从句一般在句中充当定语，但也有某些句型会将它置于句首，起补充说明之用，所以用法也就分为两大类：定语从句用法和补充说明用法。
（一）定语从句用法先行词用来修饰它所引导的定语从句，表示关系。
对于关系代词，依据作用位置和性质，分为定语从句作名词性定语，形容词性定语，和状语性定语：1、名词性定语，即修饰句中的名词或代词，先行词一般为名词和代词。
3、状语性定语，先行词一般为动词、形容词、副词，表示“时间、原因、地点、方式、条件、目的等状语”，关系代词一般是when, where, why, how等。
（二）补充说明用法定语从句也可用作补充说明，其用法也分两种：1、空位句式作补充说明，即在句首加入关系代词或副词，将定语从句放在句首，表示补充说明，而不定语性。

Step 3：找从句及主句
从句也有主语和谓语部分，从句须由一 个关联词引导，起到联系从句和主句 的作用。
关联词之后的主谓结构与关联词构成从 句。
My ambition is to work for a firm that develops computer software. 从句
非限定性定语从句，关系词在从句h came after 40 years of research by Professor Geoff Raisman, who found that cells had the possibility to repair damage to nasal(鼻腔的)nerves, the only part of the nervous system that constantly re-grows.
当一个句子只包含一个主谓结构时称为简 单句。
含有两个或两个以上独立分句的句子叫并 列句，这些独立分句处于平等的、互不依 从的并列地位。
复合句是一个主句和一个或一个以上的 从句构成。主句是全句的主体，通常 可以独立存在；从句则是一个句子成 分，不能独立存在。但是从句也有主 语和谓语部分。所不同在于，从句须 由一个关联词引导，起到联系从句和 主句的作用。
