美国知音记者MARTIN和STEFAN在咖啡馆见面了，他们落座后：
MARTIN：Hi,Stefan.Please sit down.
STEFAN:Hello,Mr learner.(MARTIN的名)
MARTIN：Oh,Please call me Martin,ok?
STEFAN:MARTIN,ok.
WAITRESS:Morning,What`re yu gonna have?
Martin:Tow coffees,please?
WAITREES:What~s it!?Ok.
STEFAN:What did she say?
MARETIN:She said:"What are you going to have?"
What"re yu gonna have?What are you going to have?
STEFAN:Ah,What are you going to have? Sometimes,I don"t understand waiters.
MARTIN:Sometimes,I do not understand!
WAITERSS:Here"y are.Two coffees.
MARTIN：THanks,she said:"Here you are !"
STEFAN:I understand.

请问：1 WAITRESS:Morning,What`re yu gonna have?服务员是说的啥意思？
2 What are you going to have?"又是啥意思？
3 这马丁到底是对斯的夫说的啥意思？是说笑话吗？

MARTIN：Hi,Stefan.Please sit down.
咳，斯蒂芬，请坐。
STEFAN:Hello,Mr learner.(MARTIN的名)
你好，勒呐先生！
MARTIN：Oh,Please call me Martin,ok?
嗷，请叫我马丁，好吗？
STEFAN:MARTIN,ok.
好的。
WAITRESS:Morning,What`re yu gonna have?
早晨好！你们想要点什么？
Martin:Tow coffees,please?
两杯咖啡怎样？
WAITREES:What~s it!?Ok.
什么？啊，好的。
STEFAN:What did she say?
她说什么？
MARETIN:She said:"What are you going to have?"
她说“你准备叫点什么”？
What"re yu gonna have? 就是 What are you going to have? 的意思。

STEFAN:Ah,What are you going to have? Sometimes,I don"t understand waiters.
哈，你想叫点什么？我有时真不懂这些侍者。
MARTIN:Sometimes,I do not understand!
有时，我也不懂。
WAITERSS:Here"y are.Two coffees.
来了。你们的两杯咖啡。
MARTIN：THanks,she said:"Here you are !"
谢谢。她说 "Here you are !"（你们在这）。
STEFAN:I understand.
我懂。（是给你们的意思）

我想看完了译文，你就理解了后面的问题了。
