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.
巍巍呼高山,汤汤乎流水。飞涧旁这段以诚相待,曲论相和的一瞬定格为千古佳话。知音难求,伯牙奏琴为子期,摔琴亦为子期。这情意如何不令人感动。而今,披肝沥胆的知音再也难觅。只缘人们拥有的纯洁太少。没有水的纯净,没有透明敞开的胸怀,着世间就无真诚可言。何不收其虚伪,展示真诚。
看着这透明如水晶的水,我们那颗被世俗之尘掩埋得太久的心,怎能没有冲见天日呼吸真诚的冲动。拥抱纯真,拥抱真诚,去成就一段马克思恩格斯般高尚的友谊,去结交一位誓友,莫逆,忘年,只要心相知,手相牵,意相同。
水教人真诚,正如叶尖那滴雨露,透明纯洁,折射出太阳的光芒。
天下之柔莫过于水。昼夜不舍的滴坠去赋予水无穷的力量。因渺小而被忽视,因忽视而暗中积攒着力量,直到将万年磐石一点点磨蚀,在世人惊叹的注目中有了穿石的壮举。
明白了持之以恒,竺可桢数十年如一日,观察记录天气情况,终成举世著名的气象学家,懂得了锲而不舍,贝多芬在静寂的世界中,用心灵演奏了命运交响曲的豪壮,有了水刚柔相济的力量,这世上多了几份执着,几份坚持。
水教人执着,正如那穿石得滴水,下坠,下坠,最终拥有成功的欢悦。
水,这就是水,水以其博大,纯净,力量感动着我,而我亦将用博大,纯净和力量去书写自己的人生,我不敢奢求拥有一段辉煌的人生,我只企盼今生无悔。
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。

车到梅西水库岸边。一下车,徐徐的清风迎面吹来,顿感神清气爽。放眼望去,只见好大好大的一个湖泊就在眼前。湖水蓝湛湛的,在阳光下波光粼粼,像眼睛一样一眨一眨。微风吹拂下,水面就起了一层一层的皱纹,一荡一漾由近及远地扩展开去。湖的中心,还有三两只小艇嵌在湖面,不响也不动。湖的对岸,是青翠的树木,因为刚长出不久的新叶,竟然在阳光下闪闪发光呢!转过身来,堤岸这边,斜斜的大草坪上嵌着四个大字梅西水库,把堤岸衬托得愈发雄伟。
我们沿着堤坝往前走,轰隆隆的水流声撞击过来,只见大坝出水口的水喷涌而出,一股股吐着白沫争先恐后地冲了出来。有趣的`是,刚好有一条鱼不小心被洪水卷了出来,只见它在湍急的水花里扑腾着尾巴却无可改变地被水卷走了。真奇妙啊,坝里的水文静如兔子,坝外的水却凶猛如老虎!
转过大坝,是一条观景长堤。这里是个绿树红花的小公园。坝外打了平台,有许多人在钓鱼呢。而最特殊的垂钓者是一棵松树!只见这树就长在岸边,树干往湖里倾斜,枝叶都快碰到湖面了,它不也在垂钓么?!
天又暗下来了,我们都担心下雨,便草草结束了这段旅程,但被关压在盒子里的心却被释放了,真好!
