what a happy day_200字

It’s the last term for us to study in our school. Thinking back on the past three years, I have taken part in many activities with my classmates. But I think the Clean-up Day is the most unforgettable of all the things that have happened. 　

　　On the afternoon of a sunny day, all of my classmates took the tools and went to the playground. Some of us swept the flour, some picked the litter up and the others watered the flowers. 　

　　At last, the whole school became brighter and cleaner. All of us felt very tired but we still felt very happy, because we all gave our own energy to make the school become better and better.
