I had neither a raincoat nor an umbrella ._______ I got wet through.

问题描述:

I had neither a raincoat nor an umbrella ._______ I got wet through.
为什么用That is why不用It was the reason,这不是句号吗?

肯定是句号才能用 that is why
reason 后面接原因的时候,连接词why一般不可以省略
所以要用就得说it was the reason why那why的先行词不是只有reason吗?那that is why中的reason省略了?
