水是一切有机体的主要组成部分,全球动植物和40亿人体内含有约11200亿吨水。人类社会依赖水而生存发展。古代,人类对水取利避害,适应水而生存;近代,人类对水兴利除害,兴建工程,开发水利,控制水害;现代,随着社会和生产的发展,地球上可资利用的水日趋短缺,水体受到污染,严重影响人类生存的环境,人类逐渐认识到水是一种重要资源和环境因素,从而在更高的水平上开始对水开展了新的兴利避害活动。
世界气象组织1996年初指出:缺水是全世界城市面临的首要问题,估计到2050年,世界2/3以上的人口将生活在城市,而全球有46%的城市人口缺水,必须平衡社会经济发展和城市淡水供应管理二者之间的关系,进行水资源的储存、输送和管理的大规模工程建设。

as we know , water is very important to man, we can’t live without water. the amount of water which is suitable to drink is less and less. but some people don’t care about it .they waste a lot of water in their daily life. even worse, they pour dirty water in to rivers. they throw rubbish into rivers , too. many rivers and lakes are seriously polluted.something must be done to stop the pollution. only in this way can we live happily. if we don’t save water, the last drop of water will be a tear-drop of us.
we know that despite the fact that seventy percent of the earth's surface is covered with water, only a little part of it is fresh water. yet the demand for fresh water in our daily life and in industry seems great. moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even rapidly. it is estimated that if such a trend continues, the fresh water on earth will be exhausted very soon. what is worse, more and more water resources are being polluted, making the water unfit to use.
in addition,we must warn the people of the importance of water and the danger we are facing.for example, in most asian societies where rice is the staple food, the water used after cleaning rice contains various nutrients for plant growth and is an excellent detergent to flush the toilet. furthermore, the intriguing idea of converting the inexhaustible sea water to fresh water supplies will be the ultimate solution.

水——我们的朋友 平达曾说过:“自然界的一切事物中,唯有水最珍贵。”是啊,水是我们的朋友,没有了水,就没有了我们。让我们一起与水做个好朋友吧! 水看见人们不节约用水,伤心地说:我对人类的所作所为感到不满,我为人类做了那么多的贡献,可人类总是滥用我。这样既会导致水源的\'流失,又会严重影响生态环境。 在生活中,处处都要用到水。洗菜要用水,洗车要用水,洗澡要用水??,这往往会浪费很多水。其实,请把水龙头开小一点,把废水再次利用,这样我们就能与水做好朋友了。比如:洗菜水可以浇花;洗澡水可以冲马桶??这样,不仅能节约用水,还对别的事物有好处呢! 如果水能这
样一滴一滴的节约起来,虽然不是太多,但是全世界人民都这样做,怎么会没有水呢? 人们可知道,世界上有许多地方水都很少,有些人,因为喝不上水,而死去,他们说:“请他们喝酒,不如请他们喝水。”下雨天,曾是他们最快乐的日子,他们可以用雨水洗澡,还能接水,以后用。他们把水当做奇珍异宝, 每次喝水都要去很远的井里去挑,那井里的水比黄河水还浑浊,比海水还难喝。由此可见,他们是多么爱水啊!如果我们能节约用水,他们的生
活难道会这样吗? 不节约用水,不但会导致水源的流失,还会影响生态环境。 有些工厂既不节约用水,还排放污水放到河流中,这样,水不仅流失了,还会影响生态环境。
