可以回答：
1、Whats up？反问对方
2、Not much just busy.没什么，就瞎忙。
3、You know, just life.你知道的，活着呗。
4、告知对方当下在做的事情
Whats up? =Whats happening? =Whats new? 见面时随口问候的话"最近在忙什么？有什么新鲜事吗？
What's up 的使用条件：必须是熟人。
如：He looked at me and said: what's up, eat fast, good way ah.他看着我说：怎么了，快吃，好赶路呀。
对于初次见面或是很久没碰面的朋友，用How's everything?或How's it going?
如：How's everything going with you?你一切情况如何？
Back at his dorm, he greeted his roommate with a "Hi, how's it going? "
回到寝室，他边想着事情边和室友打招呼“嘿，怎么样？”
