估计你是忙中出错,你问题中的“状语从句”和“定语从句”正好说反了：
the reason why 或 the reason that 属于定语从句；而以 where、when 等词引导的从句多为状语从句.
关于 the reason why 还是 the reason that 的问题,在咱们国内的英语教学中到底哪个正确的讨论中常常争论不休.其实两个说法在现实生活中都很常见,没有应该用哪一个争论的必要.学习中的关键注意点是从句所修饰的先行词在从句中是否起语法功能.如果从句在没有先行词的情况下就是一个完整的句子（所谓“同位语从句”）,why 和 that 可以换用.如：
I don't know the reason why/that his car broke down on his way to school yesterday.
当先行词在从句中起着某个语法作用时,只能用 that（有时可以省略）.如：
I don't remember the reason (that) you told me about his car breaking down on his way to school yesterday.（此句先行词 the reason 是从句的宾语.）
where只用来引导状语从句.
when 可以用来引导状语从句,也可以用来引导定语从句.当用作定语从句时,可以用that替换.
状语从句：I started my education when I was two.
定语从句：I still remember the time when/that I first went to school.
in the place 是一个介词短语作句子的状语.而in the place + that 中的 that 则是引导一个定语从句来修饰 the place 的. 估计你是忙中出错,你问题中的“状语从句”和“定语从句”正好说反了：
