怎样判定一个句子是定语从句
定语从句在句中做定语,修饰一个名词或代词,被修饰的名词,词组或代词即先行词.定语从句通常出现在先行词之后,由关系词（关系代词或关系副词）引出.
定语从句是由关系代词或关系副词引导的从句,其作用是作定语修饰主句的某个名词性成分,相当于形容词,所以又称为形容词性从句,一般紧跟在它所修饰的先行词后面.在复合句中,修饰某一名词或代词叫做定语从句.
引导定语从句的关联词称为关系词,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,绝对没有what；关系副词有where,when,why等.关系词常有3个作用：①连接作用,引导定语从句.②代替主句中的先行词,甚至可能是主句中的一部分或者整个主句.③在定语从句中充当一句子成分.注：关系代词有主语、宾语之分.一般whom作为宾语.关系代词在从句中作主语,宾语,表语,定语等,关系副词在从句中作地点状语,时间状语,原因状语等.
而在复合句中,修饰前面名词的从句叫定语从句
定语从句可以修饰名词或代词,还能修饰整个主句或主句的一部分.
可用that,who,which,why,when,whose,where,whom,as等词引导,
that,who,which,why,when,whose,where,whom,as,这些词一定要在句子中做成分,简单的说就是一个句子做前面名词或代词的定语,这个名词和代词就是先行词.先行词后面通常是紧跟着引导词：关系代词或关系副词.他们起着以下作用：一是引导从句,作为从句的重要标志；二是代替先行词;三是在从句中充当成分.
