定语从句 笔记整理
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。
定语从句小知识点总结
定语从句小知识点总结一、关系代词1. who/whom/whose：用来指人，who做主语，whom做宾语，whose做定语，也可指代事物。
2. which：用来指事物，既可以作主语又可以作宾语。
3. that：用来指人或事物，可以作主语也可以作宾语。
4. where: 用来指地点，在定语从句中作状语，表示地点。
5. when: 用来指时间，在定语从句中作状语，表示时间。
6. why: 用来指原因，在定语从句中作状语，表示原因。
以上是关系代词的主要用法，我们可以根据名词或代词的性质和引导定语从句的需要来选择相应的关系代词。
二、定语从句的引导词的省略1. 当定语从句的引导词在从句中作宾语时，可以省略。
例如：I have a friend (who/that) I like very much.2. 当定语从句的引导词指人时，可以省略。
例如：This is the man (whom/who/that) you wanted to see.3. 当定语从句的引导词在从句中作主语时，不可省略。
例如：I like the book which/that you recommended.三、定语从句的位置定语从句的位置通常紧跟在被修饰的名词或代词之后。
例如：The man who is speaking is my father.四、引导定语从句的介词在定语从句中，如果介词位于关系代词之后，其宾语必须是定语从句的第一个词。
例如：The pen with which you are writing was made in China.五、定语从句的关系代词与先行词的关系定语从句的关系代词指的是先行词，通过关系代词引导的定语从句与先行词构成了逻辑上的关系。
关系代词在定语从句中既起代词的作用，又充当引导词的作用，起连接作用。
六、定语从句的特殊结构1. “all, everything, something, nothing, none, anything”等不定代词和“the + 名词”的定语从句，其关系代词用“that”。
定语从句语法知识点总结
定语从句语法知识点总结定语从句是用来修饰一个名词或代词的句子，常常用来给出进一步的描述或限定。
以下是一些定语从句的语法知识点总结：1. 引导词：定语从句通常由关系代词（that, which, who, whom, whose）或关系副词（where, when, why）引导。
2.关系代词的选用：- that: 可以引导限定性和非限定性定语从句；用于人和物；- which: 用于非限定性定语从句，用于物；- who/whom: 用于人，在从句中作主语时用who，作宾语时用whom；- whose: 用于人和物，表示所属关系。
3.关系副词的选用：- where: 用于地点，在从句中作地点状语；- when: 用于时间，在从句中作时间状语；- why: 用于原因，在从句中作原因状语。
4.限定性定语从句和非限定性定语从句：-限定性定语从句用来限定所修饰名词或代词的范围，不能省略，不用逗号与主句分开；-非限定性定语从句用来对前面的名词或代词进行补充说明，可以省略，用逗号与主句分开。
5.关系代词作宾语的省略：- 当关系代词在定语从句中作宾语时，可以省略：即省略关系代词that/which/who/whom，但要保留动词的宾语位置。
6.关系代词和关系副词在定语从句中的不同作用：-关系代词在定语从句中充当一个成分，可以作主语、宾语、表语等；-关系副词在定语从句中充当一个状语，只能作时间、地点或原因状语。
7.先行词和定语从句的一致性：-关系代词的单复数和人称应与其在定语从句中的先行词保持一致；- 关系代词whose引导的定语从句是表示所属关系的，后面的先行词是被关系代词修饰的名词。
需要注意的是，定语从句的位置可以是句首、句中或句尾，要根据具体情况进行调整。
定语从句笔记
• 无逗号即限,有逗号非限 • 关系所用词 （who;whom;whose;which;that）
随着先行变 (先行：即被从句修饰的指人或物的 词是先行词 )
• 限定先(行)指人 who; whom要当先, that紧跟前 eg: We know the students (who/that are very naughty in our school).
as we all know; as we expected as everyone knows, as everyone can see as is known to all; 特殊： 限制性定从中先行词被so, such 修饰，关代用as
定语从句特殊用法归纳
as引导的非限制性定语从句 1) 位置灵活，可以置于主句的句首、句中或句末； 2) 先行词不可是一个词，必须是整个主句或主句的部
eg:The doctor (who/whom/that)we are talking about can speak French.
eg:The person (whom/who) I spoke to just now is our teacher 。
若前有介词 只许which;whom接，并且不省略。 eg:The teacher for whom you are waiting is coming. eg: This is the book to which I referred in my talk.
非限先(行)指人 who;whom两可兼， that滚一边 eg:His father , whom he loved dearly , died last year. eg:He has a sister , who works in Shanghai is called Liping.

定语从句授课人：Prof. WoodenPart 1 定语从句定义及概述什么是定语从句？(1)定语从句：在复合句中作定语修饰主句中某一名词或代词的从句叫定语从句。
