你家很普通可以用英语表达为 "My home is ordinary."

这个短语的来源是源自拉丁语的 "ordinarius",意思是普通的,平常的。在英语中,"ordinary" 也可以表示平凡,不特别的意思。

下面是一些英文例句:

"I don't have anything special planned for the weekend. Just some ordinary household chores."(我周末没有什么特别计划,只有一些普通的家务。)
"The hotel room was nothing special. Just an ordinary room with a bed, a table, and a chair."(酒店房间并不特别,只是一间普通的房间,里面有床、桌子和椅子。)
"She doesn't want a fancy wedding. Just a simple and ordinary ceremony with a few close friends and family members."(她不想要一场豪华的婚礼,只想要一场简单的、普通的仪式,只有几个亲密的朋友和家人参加。)
