"Where have you been?" is a common way to ask someone about their recent activities or whereabouts in Engpsh. This phrase is used to inquire about a person's activities or location during a specific period of time, such as the day, week, or month.

Here are some examples of this phrase in context:

"Hey, I haven't seen you in a while. Where have you been?"
(嘿，我很久没见到你了。你去了哪里？)

"I've been trying to reach you for days. Where have you been?"
(我已经设法联系你好几天了。你去了哪里？)

"I was starting to worry about you. Where have you been?"
