What day was it yesterday? It was Wednesday.

昨天是星期几？是星期三。

It was raining for the whole day yesterday and so what should have been a tranquil bath for the capital of China turned the city into a mud bath thanks to the abundance of dust particles in the air.

北京一整天都在下雨，本来下完雨北京应该感觉更干净一点的，但是一下雨把整个城市搞得到处都是泥浆。

What a cold day it was yesterday!

昨天真是一个大冷天！
