The Story of Li Hua
Last Friday，when my classmate Li Hua took a bus back home from school．

He saw someone eating oranges and throwing the orange skins on the car．Then Li Hua picked them up and put it in the dustbin．The passengers took photos with their mobile phones and posted them online．After knowing that，the teacher praised Li Hua．But Li Hua said that was what he should do．
I think Li Hua has set us a good example for us and we should all learn from him．It is our duty to care and protect the environment in．If everyone does something to protect the environment，the world will be more beautiful．
