Oct. 17 was Sunday and we went on an excursion to the hills nearby on that day. We played lots of games among our classmates. We were very happy at the games and got a close contact with the nature. We enjoyed the beautiful views of the nature. At our departure, the class president asked us to pick up the garbage. Most classmates started doing that, but some of the classmates thought it was not necessary to pick up the garbage left by them. I think we should pick up the garbage left by us as well as by others, because all of us need a beautiful and clean surrouding to live.
