要是我的美国人同学和我打招呼，说what✀s up, man ,我要怎么回答，可以回答I✀am good 么

除了I'am good。说法可培盯以或中清很多，what'up 本就是对话虚指，可以直接回答，也可以间接。衫前
Not much.
Just chillin. (俚语，relaxing doing nothing special. )

Nothing. Yourself?
I'm good, yourself
Good. How are you?

Doing good. (and you/yourself?)

Everything is fine.

How (are) you doing. --> How'dy
或干脆也What's up.

："What's up?"和"How are you doing?""How's it going?"以及"What's new?"……，都是美国人常说的寒暄语，一般认为是从黑人语言中而来樱渗弊，是很常脊族用的打招呼方式。

"What's up?"就是问对方近来如何，有点像中文里的“最近怎样”，通常没什么事就会回答"喊信Not much"或者"Nothing"。

-What's up?
-What's up.
老外也这样一问一答
