11、structure of restrictive relative clauses定义:在复合句中,修饰名词或代词的从句叫定语从句。Two thirds of the people who lived there were dead or injured.先行词关系词从句关系代词关系副词which,who,whom,whose,that,aswhere,when why关系代词指代从句中的成分that人/物主语/宾语/表语which物主语/宾语/表语who人主语/宾语/表语whom人宾语whose人/物定语关系代词有三个作用：1）连接作用：引导从句，把从句和它所修饰的内容连接起来；2）替代作用

12、：在从句中替代被从句所修饰的先行词；3）在从句中充当成分：作主语、宾语、表语、定语。判断定语从句的关系代词的方法：如果名词或代词后有一个句子，并且该名词或代词在句子中充当成分，则该句 子就是定语从句。主要按照以下三步来判断：1.找准先行词（定语从句前的名词或代词）。2.把先行词还原到定语从句中，看充当什么成分。3.根据先行词在定语从句中所充当的成分以及句意来选用适当的引导词。定语从句的基本用法关系代词 指代范围在从句中所作成分例句who人主语、宾语And then，how many adults，who now complain(抱怨)about the long drives to work
