二、 One possible version:
A week before Earth Day, posters were put up around our school, calling upon us to join in the actions for a greener earth.
Our class came up with the idea to make better use of used materials. We brought to our classroom worn-out clothes, pieces of cardboard and empty plastic bottles, and turned those into dolls, handbags, issue boxes and small vases. That weekend, we went to a nearby neighborhood and gave them away to the people there. All were very happy with those unexpected gifts, especially little kids and elderly people. We did so well that we were invited to share our idea and experience with all the students of our school.
We are very proud of ourselves and believe we can do more for a better world.
