In order to build a civilized city, we students should try our best to behave well in the activities.

　　It’s a good habit to keep our clothes clean and tidy. Our city should be kept clean every day. Don’t throw litter or spit about. It’s good manners to say “Thank you” and “Please”, and so on. We should never say dirty words. Be friendly to others and always ready to help the people in need. For example, when we are on a bus, we should give our seats to the old and the women with babies. We should also obey traffic rules. When the traffic lights are red, we should stop. And we’d better not talk or laugh loudly in public.

　　If everyone behaves well , our city will be more beautiful and more attractive.

　　为了建设文明城市，我们学生应该尽力在活动中表现良好。

　　保持衣服干净整齐是一个好习惯。我们的城市应该每天保持清洁。不要乱扔垃圾或随地吐痰。说“谢谢”和“请”是礼貌的，等等。我们不应该说脏话。对别人友好，随时准备帮助需要帮助的人。例如，当我们在公共汽车上时，我们应该给老人和有婴儿的妇女让座。我们也应该遵守交通规则。当交通灯是红色的时候，我们应该停下来。我们最好不要在公共场合大声说话或大笑。

　　如果每个人都表现良好，我们的城市将会更美丽更迷人。

　　As is known to us all, the surrounding has a great impact on our study and lives. In recent years, creating a green campus has been a common and popular goal for most universities or colleges. Creating a green campus has a great influence on students because most students spend their much time in campus.

　　However, in my opinion, to create green campus, what we need to do is not only to plant more trees and grasses to beautify our campus’s environment but also to create an energy-efficient and resource-cycled campus. Everyone on campus should be informed to form the habit of using resources properly and saving energy. In addition, the institutions should encourage students to use resources circularly.

　　In a word, creating a green campus needs us to make joint efforts. And we can achieve it by doing pieces of small matters in daily life, such as turning off the light when leaving.
