　　I have some advices. First, get more people to form good habits by putting posters around the hall asking them to protect our environment. Second, make people pick up their own litter. Thrid, We can ask some students to walk around the hall and watch out for those that drop litter. Then, we make them tidy up the hall after the meal.
