【答案】Dear Mr.Principal，
I am Li Hua，a senior 2 student of our school.I am writing to draw your attention to some improper behaviour among us students：littering and scribbling.
I would like to put forward some suggestions.First，it makes our school dirty and does harm to the image of our school.I always feel ashamed whenever I see this.What's more，it is clearly not appropriate for a student to litter and scribble everywhere.Therefore，I wonder if the school could place more dustbins around and set up specific rules against such behaviour.At the same time，students should be encouraged to develop good habits and better behave themselves.I'm convinced that，with the joint efforts of both teachers and students，our school will become a more enjoyable place in the near future.
Thank you for your consideration.
Yours sincerely，
Li Hua
