. Create a green campus With the development of scientific conductions, our daily life is becoming more and more convenient. But everything has both its good and bad sides, pollution has become a hot topic while the science’s building up. So the word “green” has been paid great attention among us .So do our campus. Creating a green campus is very important to build up a wonderful atmosphere. ”Green campus ” does not only means green environment, but also means positive study atmosphere, good personal qualities and refer to that the students should be educated and have an environmental sense in their mind. What’s more, what I want to stress is that it sets goals toward the future of the world. To bring “green campus” to its full play, effective measures should be taken. First, learning is the most important thing, which can strength our personal qualities. Second, we should take care our daily actions about manners and pick up waste papers here and there as we can do. Third , when you make mistakes or someone help you, you should say “sorry” or “thank you” to people with your sweet smile… Green campus make us live in a soft and warm environment. So we ought to do our best to build green campus. As we all know, a better result of study can be brought by a better study environment. As a result, it is necessary for us to build the green campus. The green campus can not only provide a good environment for our study, but also be a part of build the harmonious society. The green campus is not only the environmental being green, but also the sprite being green, which means we should do other things like helping each other or caring each other. Therefore, we should both beautify the campus environment and create a campus culture. As students, we enjoy the campus time while we have responsibility to build our green campus. In spiritual term, we should respect teachers, classmates and other people work for the school. In environmental term, we should have good habits to keep campus in a clean surrounding. 翻译: 正如我们所知,一个更好地学习环境能带来更佳的学习成绩。所以,创建绿色校园对我们而言就很有必要了。绿色的校园不仅能为我 们提供优良的学习环境,同时也能为构建和谐社会做出贡献。 绿色校园不仅仅指绿色的校园环境,也包括绿色的精神,即我们 应该互相帮助、互相关心等。因此,我们不仅要美化校园,也要创造 崭新的校园文化。 作为中学生,我们在享受美好校园时光的同时,也应该对创建绿 色校园富有责任。专业地说来,我们应该尊敬老师、同学和校园里的 其他人,应该养成良好的习惯以维持清新的校园环境。 As time goes by,the importance of constructing a green campus is gradually executed in current society,not only for that the campus is the place which aimed at developing talents,but also for the campus is a symbol to a city. The green campus not only refer to green environment,but also refer to a new idea about the ways of educating and managing the students,mainly letting them accept the knowledge and build up the spirit of loving nature and being responsible for the environment,also,letting them take an active part in the actions of protecting the environment and keep the idea of sustainable development in mind. In order to construct the green campus,we should do from two aspects.First of all,we should make every effort to study hard,aimed at becoming the knowledgeable ones with high qualities as well.Secondly,we should make ourselves more comprehensive,doing from the team-work spirit,the environmental consciousness and so on.Besides,we should be concerned about society,our motherland and the whole world,as well as learning to innovate and actively practice.
