Unit4限定性定语从句一
一 定语从句概念-----在主从复合句中，对某一名词或代词起修饰限制作用的从句。
定语从句 | 先行词 | 被定语从句修饰的名词或代词 |
关系词 | 位于先行词和从句之间，引导定语从句的词 |
关系代词 | Who，whom，who，which，that |
| 非限制性定语 关系副词 | When，where，why |
三重功能 | 1、连接功能：连接主、从句 2、指代功能：指代它前面的先行词 3、成分功能：在从句中充当句子成分 |
分类 | 限定性定语从句、 非限定性定语从句 |
| | | |
限定性定语从句：从句对先行词进行必要的描述或说明，缺少它，则句意显得不完整，从句与先行词紧密
相连，无逗号隔开。
非限定性定语从句: 对所修饰的成分(可以为整个主句)作进一步说明,通常和主句间用逗号隔开,将从句拿
自考什么时候出成绩掉后其他部分仍可成立。
I bought a pen yesterday. I am looking for the pen. I am looking for the pen which/that I bought yesterday.
二 限定性定语从句中关系代词的使用
当引导定语从句的关系词在从句中做主语、宾语或者定语时，应使用关系代词。
在从句中作用 | 指人 | 指物 | 指人或物 |
主语 | who | affectedwhich | that |
宾语 dismiss的意思 | whom(口语中可用who，可省略） | which（可省略） | that（可省略） |
定语 | who/of whom | who/of which | |
| | | |
1、who指人，在定语从句中做主语或宾语，做宾语时常省略。
I know the man who spoke to you just now。
