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。

　　盡管世界發展更快、更好,地球上的資源得到越來越少。為了保護他們,必須得做點什么。

　　要節約用水,水是生命之源。沒有水,就沒有生命。所以這對我們來說是非常重要的。我們不僅應該保護飲用水和停止污染,但也充分利用它。

　　節約用電。它是至關重要的。我們無法想象沒有它的生活將是什么樣子。每個人都應該盡力節約用電。別忘了關掉燈或其他電動機器當我們完成工作。

　　拯救森林。他們是有用的。請停止切割下來,轉而使用再生紙。讓我們的世界一個住在綠色。

　　回收有用的垃圾。大量的垃圾可以回收罐、紙、瓶子、等等。

　　以這種方式我們可以節省資源。我相信我們可以讓世界變得更美好。
