Early morning,sun farther—in—law showed smiling face,small alarm clock “ bite the bell bites bell “ the ground cries,seem to saying:“Beautiful,should get up!Should get up!!
Li Lixing,see sun farther—in—law came out,asperse on pale green branch full bright sunshine。 Li Li wore a beautiful powdery dress,wore a sky—blue pants again。 At this moment,transmit outside the window “ chirp “ cry,li Li looks up to look,a birdie is crying,seem to saying:“Li Li has breakfast quickly,I and you go to school together。 I and you go to school together。
Li Li eats breakfast rapidly,carry small satchel on the back,go to school together with birdie。
水在许多人的眼里是取之不尽的。可是我在这里提醒你,不错,在地球上确实有许多水,但你知道吗?在地球为人类提供的“大水缸”里,可以饮用的水实际上只有一汤匙。地球有70。8%的面积为水所覆盖,但其中97。5%的水是咸水,无法饮用。在余下的2。5%的淡水中,有87%是人类难以利用的两极冰盖、高山冰川和永冻地带的冰雪。人类真正能够利用的是江河湖泊以及地下水中的一部分,仅约占地球总水量的0。26%。即使如此,总体而言,世界上是不缺水的。但是,世界上淡水资源分布极不均匀,约65%的水资源集中在不到10个国家,而约占世界人口总数40%的80个国家和地区却严重缺水。我们使用水资源的方式以及污染更加剧了水资源的紧张形势。上个世纪90年代中期以来,全世界每年约有5000亿立方米污水排入江河湖海,造成35。5亿立方米以上的水体受到污染。
怎么才能让人们不浪费水呢?这个问题大家说起来容易,做起来却无比艰难。因为有有些人很不自觉,总听不进别人的意见。我就想,可不可以让人们少用自来水还能得到足够的水呢?有一次,妈妈在做饭时,她一个人忙不过来,妈妈见我正悠闲自得地看电视,便说:“别看这么多电视,对眼睛不好,你没事的'话,来帮我烧一壶热开水吧!我等着急用呢!”我听了妈妈的话,无精打采地走进了厨房,把水壶灌满水,眼睛还不禁地向电视机瞄几眼。不一会儿,水壶里就发出“咕噜。咕噜”的声音,水蒸气从水壶里飘了上来,我惊讶地发现水蒸气飘在墙上时,没过一会儿就变成了一滴滴的水珠。这可引起了我的好奇心,我想起老师说过水蒸气遇冷会变成水,我便有了一个大胆的想法:我们可不可以发明一个能把水蒸气化作水的机器呢!我希望它是这样的:底座是一个吸盘可以固定在任何东西上,把它固定好后,要有水蒸气飘出来,它的一个口会把水蒸气“收”回来,另一个口会把新鲜的空气释放出来的同时淡水也会从一个管子里流出来。
我深信只要我们珍惜,爱护水资源,把水合理用好,不滥用,不浪费,不污染水源。这个世界将会更美好。
全世界的水是一个有联系的整体,今天地球上我们拥有的水量和几千年前是一样的。地球表面的水在太阳辐射能和地心引力的相互作用下,不断地蒸发和蒸腾到大气中,并在空中形成云,在大气环流的作用下传播到不同的地域,再以降雨或降雪等形式回到海洋或陆地的表面。这些降水,一部分渗入地下,成为土壤水或地下水;一部分形成地表径流汇入江、海,再经蒸发进入大气圈;还有一部分直接蒸发或经植物吸收而蒸腾进入大气。这种过程循环往复,永无止境。
水循环是自然界自己的净化系统。通过循环,水资源得到不断的更新。在较长时间内,全球范围的蒸发与降水基本保持平衡,但在一定时间、空间范围内,其数量极为有限,并不像人们想象的那样可以取之不尽、用之不竭。不同形态水的循环速率差异很大,除生物水外,大气水和河流水的循环更替期最短,更新利用率高,是最活跃、最重要,也是于人类和生物生长发育最密切的水资源。
来之不易的自来水拧开水龙头,清洁甘冽的水便滚滚而来。其实,自来水来之不易。它们可能取自几百米深的地下,或是引自几十公里、几百公里远的某条江河、某座水库。这些“原水”,首先要在净水厂净化,曝气除去铁质,然后用混凝的办法除去细小的漂浮物、水生物,再沉淀下杂质,用液体氯、漂白粉等消毒剂***死细菌。经过检查化验,符合国家标准后,才能像其他工业产品一样出厂。清洁的水,经过密如蜘蛛网的管道,并且用水泵加压,才保证送到高层建筑或居民院里的千家万户。
社区中的水源如果你仔细观察所在的城市和小镇,就会发现很多从未想到过的水的用处。根据人们居住地点的不同,水源有的来自地下水,有的来自地表水。
地下水:土壤和岩石下隐藏的地层是地球上淡水供及的最大来源,这些水就叫做地下水。在中国,地下水是51%饮用水的来源,在农村是99%饮用水的来源。地下水是雨水沉积的结果。雨、雪和冰雹渗入地下,渗透到土壤和岩石的缝隙中。不同的地质结构(石油和土壤会保持不同量的水源。储存着最多可用水源的那一层就叫做蓄水层。蓄水层是任何可以储存足够的水资源的`自然物质,可以从井中得到。它是重要的水的来源。但是,很多蓄水层或被消耗殆尽,或被污染。这一切都是由人类对土地的滥用造成的。当从蓄水层中抽出的水量超过了水文循环中的水量时,蓄水层枯竭就产生了。
地表水:如果你曾在山上呆过,也许在附近的水库和河流边看到标志,提示你不要游泳,因为种种原因那是与饮用水的一个分水岭,那儿也许还有告示牌提示你不要乱扔垃圾造成环境污染。分水岭是地表水流向水库,湖泊之类的蓄水处要经过的区域,一段山脉或其它高地。在区别一个分水岭与另一个分水岭的高地区域——分水线,一边的溪流与另一边的溪流流向不同的方向。在一个分水岭中,水流会经过渗透过滤进入蓄水层,重新补充地表和地下水源。这个过程会过滤掉油和细菌,沉淀之类的不干净物质。
我是一滴命运多舛的小水珠。
我的历史可是很久远的,我游历过千山万水。我出生在一片“世外桃源”里的小胡里,一棵棵树木挺立,苍翠无边,似一道道绿色的屏障。阳光透过屏障,像钻石一样发闪发亮。树林里鸟儿成群,周边绿草如茵,花香扑鼻。每天会有各种各样的生物陪我玩。呼吸清新的空气,惬意极了。
可是有一天,我的家园里来了一群开着很大很大的车的工人。他们把我和我的同伴装进了一个大大的透明的水桶。听德高望众的爷爷说,他们是要把我们制作成矿泉水,卖掉供人们喝。“矿泉水”难道我们以后就要改这个名了。哎,再见了,我亲爱的“世外桃源”,我们在车里颠簸,但心里却各有所思。
从此,我踏上了未知的旅程。
当我睁开朦胧的睡眼时,自己已处在一个繁华嘈杂的大城市了。我被装在一个透明的瓶子里,瓶子里只剩下我与几位陌生的同类,其他人早已不见踪影,我惊慌失措起来,在这个陌生的城市,没有大团体的温暖,没有亲人在的幸福,没有朋友在的欢乐。我不由自主地哇哇大哭起来。就在这时,我被移动起来,一个小伙子把我们接了过去。并把我们带到了一个神奇的东西面前,只见买我们的小伙子,也就是我们的主人,“啪啪啪”地敲击下面的小方块,那个东西就显示出一排字,不一会儿,主人口渴了,只微微抿了一口,又慌忙盯着那个薄薄的东西。我们等啊等。终于,主人挪动了一下椅子。看样子是要走了,可最终却都没有看我们一眼,就那样走了。我们被孤零零地丢在桌子上,却没有人收留我们。我们欣喜若狂,可那个女人却一把把我们扔进了垃圾箱。
呼吸不到清新空气。我渐渐不适应了,开始头疼脑胀,同伴也是如此。我们被扔到脏乱的垃圾堆。以前清澈的.小水珠不见了,取而代之的是又脏又臭的脏水珠。
我恨我的主人丢下我,恨那个女人扔掉我,更恨那群工人把我送到这里。我不知道这是命运惹的祸,还是时代就是如此,难道就是这般造化弄人,随心所欲的时代吗?
人类可真是可怕,虽然有巨大的权力。拥有我们这些手无缚鸡之力的生物,但是却永远满足不了人类的贪欲与浪费。浪费是多么可恶,无数人的智慧与辛劳,无数物的美好与善良,仅仅毁在浪费两个字间,一贪间,贪欲是多么恐怖,足以让人类失去家园,失去地球。
希望以我的故事,告诉大家:地球仅一个,资源有限多,珍惜各资源,浪费不可要!

As is shown above, a leader father is sitting in the chair with a seal grasping in the hand, and a lot of money beside him. He seriously said to his son that there is more to life than just money -it is power. Simple as the picture is, but a profound truth is reveled in the picture.
I surely disagree with father ’s philosophy. As a leader, he shouldn ’t use his power to make money. It is his duty to serve people wholeheartedly, just one person said “with great power comes great responsibility ”. If he stick to his philosophy. I believe that he will spend the rest of his life in prison. What’s worse, he could affect his son ’s philosophy, guiding him in the opposite direction , nothing can be done to reverse the trend itself. The only solution is to change father ’s philosophy. Because of many greedy officials in China, it is time to reverse the trend itself by establishing new policy. As Chinese always has been our confidence that we can change for the better and better.
In my opinion, there is more to to life than just money -it is happiness, nothing is important than happiness. We can live a colorful life in our spare time.
