Today is Friday. It's time to do a general cleaning. Our classmates are divided into two groups. Today it turns to my group. As usual, we clean the blackboard, doors, windows and the floor. And we rearrange the desks and chairs to make them orderliness. Besides, we plant a couple of bonsais in our classroom. So, we must water them. They are beautiful sceneries of our class. We all take good care of them.
