The students of the first three groups will help the workers to collectthe rubbish such as waste paper , cigarette ends, plastic bags and so on. Thestudents of Group4 are going to set up five signs, which are used to tell people to take care of the flowers and trees and not to walk on the grass. The students of Group5 will keep on telling the visitors the importance of protecting the environment.
