If There Is No Water On Earth 如果地球上没有水

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.
老师总是让我们要节约用水，但是大多数学生很快会把老师的话抛之脑后。想象一下如果地球上没有水，那就就没有生命了，因为我们需要水来维持生命。动物和植物也需要水才能存活。所以我们一定要珍惜水资源，合理用水。
