Dear President，

　　I'm a Senior 3 student and I'm going to university next year.But I'm worried about the university life and I'm afraid I can't adjust to the new environment.So I am writing to ask you for some advice on how to adapt myself to the new life in a short time.

　　Most freshmen are said to be confused by the sudden change of their environment，not knowing how to deal with it.They can't take care of themselves and always feel lonely and homesick.What is more，they may sometimes lose their money，mobile phones and many other things.The new climate and food don't agree with them，which sometimes even leads to their falling ill.In addition，some students would rather live out of campus for they tend to feel uneasy to live with others.

　　As a preuniversity student，I want to live a meaningful life at university.Could you tell me how to deal with the problems mentioned above and make my university life more wonderful?

　　I'm looking forward to your reply at your earliest convenience.

Yours sincerely，
