求英语作文！假如你是李华，你有一位英国网友mary。从她发来的电子邮件中，她十分爱吃零食，现在非常胖。

Dear Mary,
I am sorry to read in your e-mail about your weight problem.Do you know that why you become fat?Because you eat too many snacks,drink too many soft drinks and do not do any activity.If you want to lose weight you must eat plenty of frush fruit and vegetables,drink a lot of water every day and do more activities.Then you will be fit and healthy.
Your,
Li Hua
