I signed up for a competition on garbage sorting on the Monday and I participated in the first round, a written test. Though there was many candidates, I succeeded entering the final with another student from my class. Last Friday where the final was held, my classmate and I played with the participants from other four classes, and answers all of the questions accurately. Finally, we won out! We were extremely happy what we brought honor to our class. When interviewing by the school TV station after the award ceremony, I expressed my prides in protecting our environment. The competition not only broadened my knowledge on the garbage sorting and increased the awareness of environmentally protection.
