One Possible Version
Recently, the “Building a green campus” program has been launched in our school, aiming at calling on us students to save energy and lead a lowcarbon life.
Right now wasting can be seen on campus. Some food is thrown away in the school canteen and plastic bags and disposable chopsticks are seen everywhere. Electricity and water is also being wasted in the dormitory.
It is everyone's responsibility to build a green campus. First of all, we'd better eat up what we buy. Secondly, we should resist disposable chopsticks. Besides, we should form the good habit of turning off the light and water tap when we don't use them.
If we change our way of life, we can build a green campus and make the earth a better place.
略。
