做宾语的句子叫宾语从句 做定语的句子叫定语从句 首先你要明白什么是 宾语什么是定语 宾语就是谓语后面的成分 定语就是修饰名词的成分. 通常宾语从句的引导词是that(陈述句)what(疑问句)等 而定语从句的引导次几乎都是which 如果后面有介词一般都前置如in which on which I don't know that you are 18year. 主语 谓语 宾 语 这句中that之后的就是宾语从句,that在从句中做一个宾语一般都省掉不写 The pen which my mather bought with my father. Which 之后的就是定语从句.修饰PEN!
