reason that后面是同位语吧，由于that后面的句子非常完整，但教程里却说reason是先行词，难道这是定语从句？
这两个tha t引导的从句都是定语从句，that是关系副词，在从句中作缘由状语。而且这个that可以省略掉的。这是非正式语体的使用方法。稍微正式的语领会用 why 来取代 that。
reason 后接关系副词 that 引导的定语从句还是后接从属连词that引导的同位语从句需要靠逻辑判断。仔细领会下面两个reason后的that引导的从句的逻辑关系。
You failed in the exam. The reason is that you didnt study hard.
You failed in the exam. You cant deny the reason that you didnt study hard. 同位语从句，翻译为“……这个缘由”。
You didnt study hard, which is the reason /why you faided in the exam.定语从句，翻译为“……是什么原因”。
目前你剖析你提问的句子中的逻辑关系，看reason后的that从句到底是同位语从句还是定语从句。
