We have only one world
It's our duty to protect the environment. I think we should keep our schools and cities clean and tidy.
以下是我的一些看法：
Here are some of my views:
不要在公共场所吐痰和到处乱扔垃圾。我们应该在城市周围种树种花。回收纸张和水是很重要的。离开房间时别忘了关灯。我们最好步行或骑自行车上学，以保持我们的街道清洁。我们必须尽力使我们的世界在未来变得越来越美丽。你这么认为吗？
Don't spit in public and throw rubbish everywhere .And we should plant trees and flowers around the city. It's important to recycle paper and water. Don't forget to turn off the lights when we leave the room. We had better walk or ride bikes to school to keep our streets clean. We must do our best to make our world more and more beautiful in the future. Do you think so ?
