在晚上用英语怎么说

在晚上用英语可以说“at night”。这个说法源于英语中“night”一词本身，意思是“夜晚”。例句如下：

I always sleep well at night.
The stars are beautiful at night.
The city is quiet at night.

请注意，虽然“at night”可以用来表示“在晚上”的意思，但它并不是唯一的表达方式。比如说，也可以用“in the night”或“during the night”来表达同样的意思。例句如下：

I always sleep well in the night.
The stars are beautiful during the night.
The city is quiet during the night.
