  I will give a speech，and the following is the content.As a middle school student，we should take good care of our campus environment.We should not tread on the grass，or climb trees.We should throw the rubbish into the dustbin.Finally，we shouldn't spit anywhere.Sputum is full of bacteria，don't bring your own germs to others.Let's work together to create a civilized campus.
   Do you have any suggestions for my speech？I look forward to your reply.
