How we can help to keep the school clean

Every body keeps their seat clean and don't throw the rubush on the corridor,so the corridor and the classroom will be very clean.

To keep the toilet clean,you should not throw the wet tissues on the floor,because it will make the florr slippery.

If you see some rubbish anywhere in your school,pick it up and throw it into the bin,so the school will be very clean!!!

串錯字， rubbish, floor. tissues is wrong.
