Teachers always ask us to save¹ as much water as possible², but most students just forget it quickly. Imagine³ there is no water on earth⁴, there will be no life⁵, because we need water to keep living⁶. The animals and plants also need water to be alive⁷. So we must cherish⁸ the water and use them in the proper⁹ 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。
