【答案】Dear Mr Principal，
    Our class has been studying some knowledge about first aid. We are all interested in it and feel that being able to give first aid when needed can make a difference before proper medical treatment is given.
    Therefore， we suggest that courses on first aid should be offered in our school. Posters about the treatment for different injuries can be put up in every corner of our campus. What's more， our school can organize the rescue drills to provide a stage for students to practice and gain experience in first aid.
    I believe having a knowledge of first aid is of vital importance. I would appreciate it if you could take our suggestions into consideration. Best regards!
 Yours sincerely，
  Li Hua
