Although the world develops much faster and better，the resources on the earth get fewer and fewer.In order to protect them，something must be done.

　　Save water. Water is the source of life. No water，no life. So it's very important for us to do so.Not only should we protect drinking water and stop polluting it，but also make full use of it.

　　Save electricity. It is crucial. We can't imagine what the life will be like without it.Everyone should do his best to save electricity. Don't forget to turn off lights or other electric machines when we finish working.

　　Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.

　　Recycle useful rubbish. Plenty of rubbish can be recycled like cans，paper，bottles，and so on.

　　We can save resources in this way. I believe we can make the world a better place to live in.

　　尽管世界发展更快、更好,地球上的资源得到越来越少。为了保护他们,必须得做点什么。

　　要节约用水,水是生命之源。没有水,就没有生命。所以这对我们来说是非常重要的。我们不仅应该保护饮用水和停止污染,但也充分利用它。

　　节约用电。它是至关重要的。我们无法想象没有它的生活将是什么样子。每个人都应该尽力节约用电。别忘了关掉灯或其他电动机器当我们完成工作。

　　拯救森林。他们是有用的。请停止切割下来,转而使用再生纸。让我们的世界一个住在绿色。

　　回收有用的垃圾。大量的垃圾可以回收罐、纸、瓶子、等等。

　　以这种方式我们可以节省资源。我相信我们可以让世界变得更美好。
