that is why and that is because 区别!

that is why结尾是why所以接结果
that is because结尾是because所以接原因

that is because后面跟的是原因，译为：“那是因为.......”
that is why? 这种用法很少见的,或者说是错句,
你在哪里看到过吗?
正确的应该是 that is the reason why (he is late)
望引起各位注意.

for example: ....that is because I answered your question, that's why I earned some points.

这就是为什么……
这是因为……

一个是这是为什么
一个是这是因为

that is why后面跟的是结果
that is because后面跟的是原因

that is why后面跟的是结果,译为：“那是（为什么）.的原因”
例如：
Tom overslept this morning.That is why he was late for work.
汤姆今天早晨睡过头了.那是他上班迟到的原因.
that is because后面跟的是原因,译为：“那是因为.”
例如：
Tom was late for work this morning.That is because he overslept.
汤姆今天早晨上班迟到了.那是因为他睡过头了.

that is why后面跟的是结果
that is because后面跟的是原因
这一定要记住哦!
