Teachers always ask us to save as much water as possible, but most students just forget it quickly. Imagine there is no water on earth, there will be no life, because we need water to keep living. The animals and plants also need water to be alive. So we must cherish the water and use them in the proper way.

老師總是讓我們要節約用水，但是大多數學生很快會把老師的話拋之腦后。想象一下如果地球上沒有水，那就就沒有生命了，因為我們需要水來維持生命。動物和植物也需要水才能存活。所以我們一定要珍惜水資源，合理用水。
