定语从句用法及注意事项
一 定语：修饰名词或代词的词、短语或从句称为定语。汉语中常用‘……的’表示。 定语主要由形容词担任。此外名词、代词、数词、副词、介词短语以及动词不定式（短语）、分词也可以做定语。
a beautiful city; a bag full of money.注意：汉语的定语无论多长都放在被修饰词的前面，而英语中的定语则不然，是一个词时，放在被修饰词的前面， 若是两个以上的词组、短语或从句则放在被修饰词的后面，
thirty women teachers ; his father; the girl in red. the boy from America
Our monitor is always the first student to enter the classroom.
falling leaves; fallen leaves; the boy playing basketball; the book bought by my mother; a reading room; a swimming pool
He is the man who you are looking for.
二：定义及相关术语
1．定语从句：修饰某一名词或代词的从句叫定语从句。定语从句一般紧跟在它所修饰的先行词之后。
2．先行词：被定语从句修饰的名词或代词叫先行词。
3．关系词：引导定语从句的词叫关系词。关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as等；关系副词有when, where, why.
