定语从句讲解与练习

1、定语从句 定语从句在句中相当于一个形容词，起定语的作用，修饰说明名词、代词或主语的全部内容。通常在被修饰的词语（即先行词）之后，由“关系词”引导。定语从句的三种功能：1.连接功能：连接从句，引导一个定语从句2.指代功能：指代先行词3.语法功能：在定语从句中充当句子成分(定语从句中的关系词分为关系代词和关系副词两种)that which who whom whose when where why语法关系词指代主语宾语定语表语指人whothatwhomthatwhosethat指物whichthatwhichthatwhosethat注: 关系代词在句中充当主语、宾语，因此定语从句中不能再出现关系
