As middle school students, we should save recourses and protect environment of the school and the city. We should reuse the reusable things, such as paper and glass. We should sort the rubbish. When we leave the place, we should turn off the lights and after using the tap, turn it off. We shouldn’t step onto the grass, and we shouldn’t pick the flowers. We can’t burn the useless things. Try to go to school by bike or on foot. Don’t use paper cups. Every year we can plant many trees. If we all try our best, the environment will be better and better.
