水是生命起源和存在的基本前提,古人称它为“万物之源”。人类和其他生物的新陈代谢和生活离不开水,人类的生产活动高不开水,没有水就没有生命。然而世界上有许多国家面临缺水的危机,我国的人均淡水资源还不到世界平均水平的四分之一。近年来,由于用水方式落后等原因造成水资源惊人的浪费和严重的水体污染,使我国缺水的形势更为严峻。节约用水,保护水资源,是我们教育者的艰巨任务。
Water is the basic premise of the origin and existence of life, which the ancients called “the source of all things.” The metabolism and life of human beings and other living things are inseparable from the water. The productive activities of mankind are not high in boiling water, and there is no life without water. However, many countries in the world are facing a crisis of water shortage. Our country’s per capita freshwater resources are less than one quarter of the world average. In recent years, the alarming waste of water resources and serious pollution of water bodies caused by backward water and other causes have made the situation of water shortage in our country more severe. To save water and protect water resources is a daunting task for our educators.
