"You have to get the pickled watermelon," Mahin, who was stuck at her day job, said. "Elina, what was the word you taught me yesterday?" "russki."

“你必须得拿到那个腌制的西瓜”Mahin遇到了麻烦，“米勒，你昨天教我的词是什么来的？”

Ll: We both know I wasn't really born yesterday. What I meant was that I have known you for so long that I can tell you are looking forward to a romantic Valentine's day gift.

我明白了，you said you weren ' t born yesterday，是因为你觉得我肯定想要你送情人节礼物给我。

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！

What day was it yesterday? It was Wednesday.

昨天是星期几？是星期三。
