假如你叫Sandy，你收到了你的英文笔友Lucy的来信。请你用英文给她写—封回信，针对她的问题，谈谈你的看法，并给出可行的建议。
Dear Sandy,
I am very glad to enter my school. I enjoy the life here except for the school lunch. I prefer hamburgers,ice creams and potato chips,but we are not allowed to order them according to the school rules. I usually have little for lunch and I often feel tired and can't follow the teachers in the afternoon classes. What should I do? Do you have any good ideas? Please write to me as soon as possible.
Yours sincerely,
Lucy
