教学准备：课本、教辅资料
教学过程：
step1.Lead-in
a beautiful girl (adj做定语)
a teacher in the front of our classroom(介词短语做定语)
a falling leaf (现在分词做定语)
a leaf fallen from the tree (过去分词做定语)
some housework to do (不定式做后置定语)
小结：修饰n或pron.的词或短语都是做定语
引入提问：若用一个句子修饰n或pron.且放于其之后，使用一个连词来连接，就是一个定语从句。
含义：被修的n/pron.就是先行词
连接定语从句的词叫关系词
关系词分为关系代词：that, who, whose, which, as
关系代词：why, when, where
其中what, how不引导定语从句，关系词和先行词在从句中所做成分一致
