题目

I work in a restaurant与I work at a restaurant区别?
work in和work at区别在哪?
我看到的大多数句子都用work in,不是work at
he's a waiter at a restaurant.
这里为什么用in?

答案

in 指大地方,at 指小地方,at也可以理解为在旁边.
He works at a restaurant in New York.
他在一间餐馆工作,在纽约.
这里 restaurant 是小地方,New York 是大地方.
He is sitting at the table.他坐在桌子旁边.
He is at Paris in France now.他现在在法国,巴黎.
