水资源的利用和保护论文结语
节约用水,人人有责,我们每个人都应该有这种意识,只有每个人行动起来,从自己做起,从身边的一点一滴做起,爱护我们周围的环境,珍惜地球上的资源,我们的生活才会更美好。
开头:现在,中国科技发展日新月异:发明了核武器、神七升天、成功举办了奥运会……人们都过上了幸福安康的生活。但是,人门是否想过祖国的环境正在一步一步的恶化? 就拿水资源来说,虽然地球上8%的面积被水覆盖,但世界水资源中有2%是海,剩下的70%是固体冰川,也就是说,真正可以被利用的水资源还不到1%。这真是少得可怜。尤其是我国人口众多,淡水资源并不丰富,每到秋冬季节,就有几十个省市,几千万人口受到干旱的威胁。结尾:珍惜水资源,保护水资源,节约水资源。让我们从现在做起,从我做起,从点点滴滴做起,珍惜地球母亲赐予我们的一切自然资源,使我们的家园年年春光灿烂…… 希望你们能研究并采纳我的建议
开头:水是人类赖以生存的的宝贵资源,是一切生态环境所必需的重要因素,因此次我们要珍惜水资源。结尾:让我们携起手来珍惜自然资源,共营生命绿色!
保护水资源 水,我们生活中所必需的物资。没有了它,任何生物都不可能生存下来,据资料记载我们地球的71%空间都被水所占据,可是在这数量巨大的水资源中,最终能被我们真正利用的,却极少极少。 淡水与咸水 地球的71%都被水覆盖,其中海洋是地球上最大的水体,在海洋中,水分不断蒸发,河水从地球各处带去的盐分留了下来,浓度不断增加,形成了咸水。冰盖、冰川和永久积雪是陆地上主要淡水水体,冰川在两极和两极至赤道带的高山都有分布,由于大多数是难以利用的极地冰川,所以最终可以为我们所用的大约只占现在发现水资源的4%。与其他资源不同,水,这种由氢和氧组成的物质,作为一种资源有着唯一性,有着不可替代性, 必须利用科学手段将咸水转化成淡水。 水的循环 水存在三种形态——气态、液态、固态。常温下,水以液态的形态存在;高温时水分子活跃开始上升,成为气态;低温时,水就成了固态的冰。大自然中排除生物因素,水不会消失。可是现实中人类、动物、植物甚至机械所耗费的水、污染的水不计其数。原本,水以天为周期不断地在海洋、陆地、天空,三处循环。而现在,因为人类的破坏,水循环也开始减慢,循环周期越来越长,已经有停滞的可能。 人体中的水 水还是我们人类也是所有生物必需的物质。在人体中水大约占70%,人脑中的80%也是水连骨骼和牙组织中都有10%的水血液中更是有90%。看了这些数据,我们不难发现水是人体中最多的物质,它在人体中有着平均体温保证新陈代谢的重大功能。可见,水在人体中也有着如同大自然中一样的循环,这不得不说是一个巧合。 我国地大却水却不“博”,是一个水资源十分稀缺的国家,许多地方的人甚至还喝不到水。水,人人都需要,人人必须珍惜。让我们行动起来,从身边的小事做起,从节约每一滴水开始。为了更多的地方,更多的人们可以喝到水用到水,让我们珍惜自然之水,保护生命之水。因为我们深知------水,不只属于人类,它同样属于地球上的一切生物。让我们保护水资源,共营生命绿色。
水资源利用与保护论文结语英文
People can't imagine life without Without it, the earth we live on would be a dead There would be no trees, no crops, no animals and no So water is considered to be next to oxygen in Although nearly three quarters of the earth's surface is covered with water, it is sea water and The demand for water is increasing, while water resources are Agricultural production needs enormous amounts of water, so does Besides,the rapid growth of population makes it more and more difficult for people to survive because of the water So water shortage has become one of the most serious Fortunately, people have realized this pressing problem and are trying to find ways to salve First, people are urged to economize on Second, measures are taken to protect water Third, circulating water is used for industrial purposes over and over in factovies and treated sewage water is used for irrigation in farming Directions: For this part, you are allowed 30 minutes to write a composition on the topic Global Shortage of Fresh W You should write at least 100 words and you should base your composition on the outline (given in Chinese) below:1.人们以为淡水是取之不尽的(提示:雨水、河水、井水……);2.实际上淡水是非常紧缺的(提示:人口增长、工业用水增加、污染……);3.我们应该怎么办。Global Shortage of Fresh Water There is fresh water in rain, in rivers and This fact leads us to think that fresh water is everywhere and it will never be used up in the But the fact is that such a belief is unfortunately wrong and possibly 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 Yet the demand for fresh water in our daily life and in industry seems Moreover, with the expansion of the population and development of industry, the amount of the fresh water needed will increase even It is estimated that if such a trend continues, the fresh water on earth will be exhausted very What is worse, more and more water resources are being polluted, making the water unfit to We still have time if we begin to act right We must warn the people of the importance of fresh water and the danger we are We should control the wastes produced by We should also develop new ways to use our limited fresh water more economically and recycle the used In short, the global shortage of fresh water can be solved if some measures are taken right
Water is very important to the human But now many rivers and lakes are And what shall we do ? We can do like this: First we must prevent the factory from pouring waste water into the river Second we should stop people from throwing litter into the Many kinds of litter may pollute the Finally we can tell the visitors how important the water After doing these things,I think water will become cleaner sooner or 水是对人类非常重要但是现在许多河流和湖泊受到污染。而我们该怎么办?我们可以这样做:首先,我们必须防止工厂将污水倒入河流。其次,我们应该阻止人们把垃圾扔进河流各种垃圾会污染环境。最后,我们可以告诉参观者,水是多么重要。做了这些事情后,我认为水将迟早变得更清洁。

水资源利用与保护论文结语格式
呵呵,晚了,写了也不得学分了。小样
据分析,家庭只要注意改掉不良的习惯,就能节水70%左右。与浪费水有关的习惯很多,比如:用抽水马桶冲掉烟头和零碎废物;为了接一杯凉水,而白白放掉许多水;先洗土豆、胡萝卜后削皮,或冲洗之后再摘蔬菜;用水时的间断(开门接客人,接电话,改变电视机频道时),未关水龙头;停水期间,忘记关水龙头;洗手、洗脸、刷牙时,让水总是流着;睡觉之前、出门之前,不检查水龙头;设备漏水,不及时修好。
节水短文大家都应该知道,中国是一个水资源贫乏的国家,许多地方的人饮水问题都很难解决,有时喝的水还不达标,患上一些难以治愈的疾病。而我们身为中国人,就应该节约用水。姥姥家养了两大缸鱼,最大的一缸把我放进去都绰绰有余,但姥姥从来都不浪费水。她每次把从缸里换出来的水分为两盆,一盆流着冲厕所,一盆浇花,一举两得。而有些人却不在乎浪费的这些水,身为小学生应该告诉周围其他邻居节约用水,做到:1不浪费水。2节约用水。3利用水。比如:洗衣服的水,洗米的水……都可以再利用。这样才是一个身为北京人应该提倡的,为了更多的人喝上干净的水,让我们一起为了这个目标努力吧!
