如何回答?

Hello, David!

Hey, James!

　
How are you doing?
How are you?
Howdy?



美国的店员在你结账的时候都会问这一句, 所以要有心里准备, 只要答一声, good 就好, 不用再反问.

Good! (Pretty good)
I am great.
I am Fine.
I am all right.
I am doing good.
I am wonderful.
Not bad.
Well, a little bit tired.

礼貌上, 你答完之后, 要再反问: How are you doing?

What's up?

有没有什么事啊?

Not much!
Nothing much!
Nothing special
没什么

How is everything going?
How is going?
How have you been?
第二句是第一句的简称, 如在路上遇到, 匆匆走过, 就说第二句就好了!

Not much.
Tired.
Good!
你当然也可以回答其它的, 如 Busy, 但 Not much 或 Tired 比较常听老美说.

Happy weekend?

星期一见面时可以问这一句.

I had homework on my head!

我满脑子都是功课! (这句可视情况回答)

How was your trip?
How was your flight?
How was your party?

如果知道别人昨天做了什么事, 可以关心一下, 记得这个句型,   How was your xxx ? 很有用. 不要划蛇添足!

Well, That's good.
Well, That's ok.
Well, That's all right.

Well 是发语词, 没什么意思, 但常用. 如果想继续跟对方聊下去, 可以把经过讲给对方听, 不然这样讲就够了
