定语从句
定语从句：
1.在复合句中，修饰某一名词或代词，并充当其定 语的从句叫做定语从句。
2.被定语从句修饰的 名词或代词叫做 先行词。
定语从句常放在先行词的后面，由关系代词 who, which, that等引导。
先行词：是被定语从句所修饰的词 （通常是名词或代词）
关系词的作用：
1.引导定语从句
2.在从句中替代先行词，在定语从句中充当一定的成分，通常是主语或宾语，作宾语时常可以省略。
定语从句：
先行词+关系词(that/which/who)+从句
修饰
3.关系代词的使用取决于先行词,
当先行词是人用 who / that （作主语或宾语）
当先行词是物时,用that或which(作主语或宾语）(关系代词作宾语时可以省略,作主语不能省略)
4.当先行词是物，介词之后只能用which,不能用that.
