定语从句的概念

一、定语从句的概念 在复合句中做定语，修饰某一个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，由关系词引导。定语从句的结构是：先行词+关系词+定语从句。二、定语从句的关系词引导定语从句的关系词有关系代词和关系副词，常见的关系代词 包括(that， which， who，whom， whose）等，关系副词包括(where， when， why)等。关系代词和关系副词放在先行词及定语从句之间起连接作用，同时又作定语从句的重要成分。（主语和宾语等）Eg: 1. Do you know the boy that/who is from Japan.（主语） 2. I dont like the book that/ which is boring. (主语) 3.I dont know the time when we will start.(状语)三、学习关系代词that, who, which, whose的用法先行词关系词代词作用能否省略人that, who主语,宾语否能物that, which主语,宾语否能人或物thatwhose主语,宾语定语否1.
