有人下楼英语怎么说

"有人下楼"可以用英文表示为"someone is going downstairs"或者"someone is coming downstairs"。

这个表达来源于英语中"downstairs"一词的含义，它指的是楼梯的下面或者楼房的一楼。因此，当有人要离开楼上的房间并去到楼下的房间或地方时，就可以用"going downstairs"或者"coming downstairs"来表达。

下面是一些例句：

I'm going downstairs to get something to drink. (我要下楼去找点儿喝的。)
Can you come downstairs and help me with this box? (你能下楼来帮我搬这个盒子吗？)
I heard someone coming downstairs, so I went to see who it was. (我听到有人下楼，所以我去看看是谁。)
We need to go downstairs and check the mail. (我们需要下楼去看看邮件。)
