Question:

　　Miss ABC:

　　I am very glad to have the chance to talk to you here.I have two questions.First,can you tell me the differences between the university and college? Second,what's"How d'ye do"mean?

　　I look forward your reply. Thank you very much.

　　NANCY

　　Answer:

　　Dear nancy,

　　university一般指综合性的大学，比如哈佛，北大这些包罗万象的大学；college一般指学院，专门性很强的大学，也可以是university下的一个学院。

　　你的第二个问题其实是一个口语化的句子，how do you do？

　　Yours abc
