人民公社的特点是（    ）

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
