1、专题语法课Attributive clause 定义及其作用：定义及其作用：定语从句是中学阶段英语语法中十分重要的一个语法项目，它在句子中出现的频率很高。对正确理解句子的意义起着举足轻重的作用。定语从句可分为：限制性定语从句和非限制性定语从句。定语从句一般都紧跟在它所修饰名词后面，所以如果在名词或代词后面出现一个从句，根据它与前面名词或代词的逻辑关系来判断是否是定语从句。定语从句定语从句先行词的作用先行词的作用被定语从句所修饰的名词或 代词叫做“先行词”。引导定语从句的词叫“关系词”。关系词有两个作用：一、引导定语从句二、代替先行词在其引导的定语从句中充当一定的句子成份。理解和牢记这两条概念，

2、弄清楚关系词在定语从句中充当什么成分，是掌握定语从句的关键。v修饰物体时关系代词修饰物体时关系代词that和和 which的区分的区分v使用that的情况：v1、当先行词是nothing,something,anything,all,each等不定代词时。veg.Do you have anything that is important to tell me?v2、当先行词被all,any,some,no,not,every,each等修饰时。veg.I have some books that are very good.v3、当先行词被形容词最高级、序数词所修饰时。veg.This is
