During the winter vacation, the students in our class joined in a meaningful activity in which all of us did our bit for the community.
Fist we went to visit an old lady who lived all alone. While we were in her home, one of us chatted with her and the rest helped do a thorough cleaning. We swept the floor and dusted the table. When the work was done, the house looked really neat and tidy then we went to the sports center, where different sports facilities needed polishing. We set out to work at once. In no time everything was dust-free. To make the environment clean, we also picked up the litter on the grass and along the paths. As the Spring Festival was around the corner, we put up New Year decorations on the billboard and a poster with the characters Happy Chinese New Year on it.
Having done all these, we saw a more pleasant community. Tired as we were, we felt happy as all of our work paid off.
