He does not understand/know the cause that/which makes him commit such a mistake.
定语从句用于修饰定于,原因 cause, 主句为他不明白(原因)
也就是说按照主句为一级,从句为二级的规定来看这个句子的话,排列应该是如下
He does not understand/know the cause(一级)。 The cause makes him commit such a mistake.(一级)
然后用定语从句连接词that或者which将句子转换为一级加二级的形式如下
He does not understand/know the cause (一级)that/which makes him commit such a mistake(二级).
这差不多就是定语从句,从句起定于作用,修饰的是宾语
