As we all know,it's very important for us to keep our school clean and tidy,because we are junior students,it's our duty to keep the school clean.However,we can still see that there are many wastes on the ground,such as plastic bags,cans,old batteries and so on.
Therefore,we have to protect the environment as soon as possible,such as we can't spit anywhere and we shouldn't throw rubbish anywhere,for it's very rude.We also need to try our best to do some cleaning.In this way,I'm sure that our school will be more and more beautiful in the future.
