定语从句(attributive clause)
根据初中所学知识，请用红笔标出下列**中的定语。
定语从句的定义及其作用：
定语从句是又称形容词性从句，在句子中起定语作用，修饰一个名词或代词，有时也可修饰一个句子。受定语从句修饰的词叫先行词。 定语从句的作用和作定语的形容词、介词词组、分词词组相似，有时可以相互转换，例如：
金发女孩可译作a blonde girl ，a girl with blonde hair或a girl who has blonde hair。定语从句通常由关系代词that/ which/ who/ whom/ which/ as或关系副词when/ where/ why引导，这些词既指代主句中要说明的名词或代词， 又充当从句中的某个句子成分。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。

1. you are the right man whom we are looking for.
2. i’ve spent all the money that was given by my parents.
3. i will never forget the day when i joined the party.
