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.
一个炎热的中午,我准备打电话给爸爸,叫他回家的时候给我买雪糕。“嘟—嘟—嘟”电话很快就拨出去了,我心里砰砰地跳,不知道爸爸会不会同意。
哪知,电话那边传来一个熟悉的声音。我对那个人说:“我找向XX。”“对不起,他不在。”我觉得很奇怪,向XX是我爸爸,怎么可能不在?经过反复询问,原来电话线出了问题,我跟13年后的自己通上了电话。
于是,我好奇地问:“你现在是什么职位?”“不算好哇,只是一个公司的普通职员。”电话那边用遗憾的语气回答到。顿时,我脑袋一片空白,无言以对。电话那边又说:“就因为你读小学不用功,读高中不用功,最后没考上理想的大学。”
我又问:“那总经理是谁?”
“是叶梓。”
“可他学习还不如我呢!”
“虽然他没有你聪明,但他进步非常快,被董事长看重,所以他当上了总经理!”
我脑海里突然出现叶梓在课堂上的表现,每当老师提问时,他总是把手举得高高的,虽然偶尔会回答错误,但他总是在课间休息时,安安静静地在教室里,仔细思考课堂上不理解的问题。想到这儿,我感到无比惭愧。
未来的我又说;“你知道为什么我只是一名普通员工吗?虽然我学习成绩比叶梓好一点儿,但我少了一股努力和坚持的劲头。”
我和未来的自己聊了很久,直到傍晚才挂断电话。我又回到小书桌前,已经忘掉了叫爸爸买冰淇淋的事。我握住笔,自己对自己说:“我一定要努力,把握住自己的未来。”
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。
