水是生命之源 .地球上所有的生命都起源于水 ,也依赖于水 .所以中国古老的“五行”之中才有水的一席之地 ;美国的太空探测器到达火星后最先寻找的也是水 .全球性的水荒已闹了多年 ,虽然我国有黄河、长江等大江大河 ,但分布不均 .中国是缺水国家 ,但水资源浪费现象比比皆是 ,致 Water is the source of life. All life on earth is derived from water, and it also depends on water.

China is a water-scarce country, but the phenomenon of waste of water resources abounds.
