A meaningful Activity
Our school has now started an activity called “Build Civilized Classes and a Harmonious Campus.” The topic is “ Get Rid of Bad Habits and Greet Civilization”.
Bad habits do exist. Some students throw rubbish everywhere or spit in public. Some wear long hair. Others are even addicted to smoking and drinking. We require that the students break away from these bad habits.
We urge the students to wear their school uniform and be polite to others.
During the activity, we’ll hold a picture show, a competition of classroom and dormitory decorations and so on.
We all hope that we’ll build each class into a civilized one and our campus into a harmonious place.
