“今天下雨”用英语怎么说

It will rain today.
It is going to rain today.
It's rainy today.
It is to rain today.
It is about to rain today.

Today is rainy
Today is raining
It is rainy today!
It is raining today!

It's going to rain today.
这个问题对中国人来说不难却易错。仔细看中文，里面没有主语，所以我们就 容易把"今天"当成主语：Today is going to rain. 实际上，英语里面通常用it当作老天爷，刮风下雨下雪等都用it. 而把today当作时间状语， 放在最后。

It will rain today.
It is going to rain today.
It's rainy today.

Rainy today.
It's raining today.
