Hello everyone, I think there are some bad manners in our class.
First, the lights are still on while there is nobody. We have to turn off the lights when we leave the classroom.
Second, there is too much waste paper around. We shouldn’t throw rubbish about. And we should pick it up.
Third, The students on duty can’t clean the blackboard on time. That makes our teacher unhappy.
Fourth, there is so much noise in the classroom. It’s impolite.
At last, some students sleep in class. We should listen to the teacher carefully.
We must pay attention to them, and do our best to do well.
