请问That's why +陈述句；和That's because+原因状语从句的区别；

that's why +句子（句意为这件事的结果）
that's because+句子（句意为这件事的原因）
比如我们要表达“她没有考过的原因是没有复习”,在两个不同的上下文可译为：
That's why she didn't pass the exam.（这时的that就指“她没有复习”）
That's because she didn't review.（这是的that就指“她没有考过”）
也可译为：
The reason why she didn't pass the exam is that he didn't review.

(1）“That is why...”与“That is the reason why...”同义， 只不过从语法结构上讲， “That is the reason why...”中why引导的是—个定语从句， 将其中的the reason去掉则与“That is why...”结构一样， 例如：
That is (the
reason) why I cannot agree. 这...

第一个翻译成 那就是为什么…… 陈述句说的是结果 比方说that is why i am late 这就是为什么我迟到
第二个翻译成 那是因为…… 后面的状语从句时原因 例如that is because my father foget to wake me up 那是因为我爸爸忘了叫我起来
