“Business”除了生意，買賣的意思，在口語中，它使用的范圍非常廣。比如一個固定表達：

None of your business.
雨女無瓜（與你無關(guān)）

這里的business和生意一點關(guān)系都沒有！

那have no business是什么意思呢？

Meaning
1.to do something that you should not be doing
做你不該（無權(quán)）做的事

2.to have no right to be somewhere
不該（無權(quán)）去某個地方

在句中通常用have no business doing sth.

Example Sentences:

You have no business discussing my personal life with your friends.
你無權(quán)和你的朋友討論我的私生活。

You have no business coming to my office.
We will deal with this situation when I get home.
你不該來我辦公室。
回家后我們會處理這個情況。

You have no business telling my boss that I was late to work.
你無權(quán)告訴我老板我上班遲到了。
