In English, people often say ‘what's up?’ instead of ‘hello’ or ‘how’s it going?’ when
meeting someone they know well.

我们都知道，问候是英语学习中最基本的礼仪。那么在口语中what's up?是什么意思呢？

what's up?的意思是你怎么样了？你好吗？相当于我们说:

Hi,hello.

或者

how's it going?

意思是你最近过得怎么样？

下面方向标给大家举3个例子：

For example:

1. Hey, bro! What’s up? I haven’t seen you for a long time.

2. What’s up with you? You look just like you’ve seen a ghost.

3. Can someone please tell me what’s up with the photocopy machine?
Did you get it?

See you soon!
