关于地球的论文1000字开头怎么写

那天,我做了一个梦,梦见自己成为最后一批离开地球要去火星生活的移民。再见吧,生我养我的地球。再见吧,蓝色的海洋,再见吧,曾经的绿洲。这一切从今不会再有了,我要离开你,去一个陌生的星球,虽然我不想离开,一直留到最后,但是,我们始终要分别。 飞船吐出明亮的火焰,在灰暗的空中如此耀眼。我透过舷窗的玻璃俯瞰地球,我不敢相信,这就是我曾经住过的地方,只见地球上一块块突起的黑色土堆,就像癞蛤蟆那难看的脊背,不见了昔日葱葱的绿野——那是山;一汪汪都是不用工厂加工的碳素墨水,太阳掉进去也没有了光辉——那是海;空中飘浮的是一条条黑色的丝带,像是为了寄托无限的哀伤,轻轻裹在地球的周围——那是云。 这是我们曾以拥有的地球吗?是谁让她变得如此狼狈?是我们,是我们没有保护好她。曾经我们向河里排放污水,向海里倾倒垃圾,向空中排放有毒废气,对动物痛下杀手,对树木森林毫不珍惜……哎——飞船已经离开了地球的大气层。地球离我也越来越远。渐渐地我只能看到一个模糊的黑影,像迷雾,又像魔鬼。不知不觉我已进入了梦乡。 我又看到了地球,我看到了地球上绿色的田野,我闻到了野草的清香,我嗅到了水果的香味。啊,你看,那是小鸟在自由地飞翔,还有美丽的蝴蝶;再看大海,碧波荡漾,波光四射,海鸟在争抢食物,鱼儿在嬉戏,海上的船儿随波逐流,船上的人正在瞌睡;一片片的白云悠闲的飘荡在地球周围,像棉花,像积雪,盖住山头,看着草原上白色的羊群,轻轻拥抱着空中忙碌的飞机,默默地守护着大地;地上一片片欢声笑语,人们在跳着,笑着,在庆祝幸福的生活,在呼吸着清新的空气…… 我笑了,是最开心的笑,我见到了我的家。 突然一阵振动。我不想睁开眼睛,我想留住梦中美好的一刻。我醒了,这样我可以记住我想的一切了。飞船着陆了,我们要下船到自己的新家啦。大家都吵起来了,争着要下飞船,有一个人拉着我的手,要我走了。 我睁开眼睛,怎么是妈妈呢?怎么会是这样呢?我还在床上,“起床要上学啦——”我看看表,哦,是上学的时间了。 我一边走一边想着刚才奇怪的梦。一路上是黄黄的树叶,吵闹的汽车声、人声、机器声,臭水沟……我要是直能上火星多好啊,火星上一定比地球好。 不,我还是要在地球上。地球本来是好好的,只是我们人为的破坏让她变成了今天的样子,既然是我们破坏了地球,我们有责任让我们的地球变得更美丽。地球是生我养我的地方,我为什么要走呢?我们不能破坏地球,要好好保护她,因为我们只有一个地球。是地球养育了我们。

地球是神圣的,美丽的。她是人类的母亲,是生命的摇篮。原来的天是蔚蓝色的,可以清晰地看见白云朵朵,地面上干净清爽,四处飘来鸟语花香,这是多么美丽的景色啊! 现在天不是那么蓝,据专家介绍是人为造成的。有工厂排放的废气,汽车排放的尾气。地上有污水成积。时常有那么些不讲卫生的人随处乱扔果皮、纸屑,日久堆积,没有人去管就那么睁眼闭眼的从旁边走过,这就给害虫制造了生存的有利条件。有许多水利资源被污染,鱼儿可怜地浮在水面上,这样的水还可以让我们安全饮用吗?如今我的地球母亲已经严重生病了。 我们人人都知道保护环境,讲究卫生,人人有责,让我们来爱护环境保护美丽的地球吧!地球永远是我们的家!

人类的科技正在飞速发展,对能源的需求也越来越大,据科学家推测,再以这样的速度开采下去,我们最为依靠的能源——石油将在本世纪末彻底枯竭,像石油、天然气、煤这样的不可再生能源,用一点,少一点,寻找新型能源,已是我们人类迫在眉睫的任务。 让我们大胆的想像一下,未来世界的人类,使用的能源将会是怎样的匪夷所思呢? 让我们在头脑中构建一个神奇的国度,河上有水车——水能;田野上耸立这无数的巨大风车——风能;城市里的所有楼房的房顶都是太阳电池板——太阳能;所有的马路、人行道、走廊的地面,都是一种奇怪的材料铺成的,把汽车、人、动物运动时产生的电能、热能收集起来——摩擦能。有一种工厂,用植物生产植物燃料;有一种交通工具,上天下海,遨游宇宙,无所不能,他的燃料竟是太阳能和生物燃料。有一种灯,只要河流不息,它就可以永远明亮。 幻想一下未来孩子的生活。阳光洒在小女孩乌黑的头发上,迎着晨曦,小女孩睁开了眼睛,粉嫩的小手从柔软的鹅绒被里探出来,按了一下床头的第三个红色按钮,楼下厨房中,传送带从冰箱里取出食材,用电热炉加热,送到了餐桌上。这一切都是依靠地面收集来的热能和电能完成的。 享用完美食,背上书包,坐进了智能××车中,点了一下荧幕学校的位置,××车用早上收集来的太阳能结合了植物燃料的等量,瞬间来到了学校门前…… 未来,这个充满希望的词语,让我们无限憧憬,未来,人类会更加辉煌吗?人类在不断的前进,未来人类要依靠什么样的能源呢?让我们畅想未来,去发现更多的环保能源来造福世界。

When I first conceived of Earth Day, a global holiday to celebrate the wonder of life on our planet, I thought long and hard about the day on which it should It must be One that might be accepted universally for all of   When the Vernal Equinox dawned on me, I immediately knew it was The Earth tremor that shook our California dwelling at that moment seemed an omen of What could be more appropriate than the first moment of Spring, when day and night are equal around the world and hearts and minds can join together with thoughts of harmony and Earth's Just as a single prayer can be siginificant, how much more so when hundreds, thousands, millions of people throughout the world join in peaceful thoughts and prayers to nurture neighbor and   And so it came to pass we initiated the celebration of Earth Day on March 21, The first Proclamation of Earth Day was by San Francisco, the City of Saint Francis, patron saint of Designating the First Day of Spring, March 21, 1970 to be Earth Day, this day of nature's equipoise was later sanctioned in a Proclamation signed by Secretary General U Thant at the United Nations where it is observed each Earth Day was firmly established for all time on a sound basis as an annual event to deepen reverence and care for life on our   While other dates have been called Earth Day it is obvious that a singular Earth Day is needed and that the original choice of nature's day is More attention for this fact will increase the influence of Earth Day and its   Every effort to encourage Earth care is to be But just as more than one birthday each year for an individual would diminish the real birthday, calling other dates Earth Day detracts from the authentic day -- which can provide a more meaningful focus and obtain more unity in our The nature of the March equinox provides a reason for an event at the same time all over the   Other events leading up to or following could be called Earth Festivals, or given other Then events can complement each other and increase awareness and care for our planet and its In the midst of this will be Earth Day, where the United Nations Peace Bell rings at the moment Spring begins and hearts and minds join all over the

Earth Day was first observed in Spring of An estimated 20 million people nationwide attended festivities out of which came the largest grassroots environmental movement in US history, and the impetus for national legislation like the Clean Air and Clean Water A By the twentieth anniversary of that event, April 22, 1990, more than 200 million people in 141 countries participated in Earth Day Since the first Earth Day, however, the environmental movement has increasingly transformed itself from a largely grassroots, citizen crusade to a professionally-organized, established special

地球形成时基本上是各种石质物的混合物,如果积聚过程持续~年,则短寿命放射性元素的衰变和固体颗粒动能的影响都不大。初始地球的平均温度估计不超过1000℃,所以全部处于固态。形成后,由于长寿命放射性物质的衰变和引力位能的释放,内部慢慢增温,以致原始地球所含的铁元素转化成液态,某些铁的氧化物也将还原。  When the earth was formed basically is a mixture of various stone, if the accumulation process continues in ~, short life of radioactive elements decay and solid particle kinetic energy are The average temperature of the earth's initial estimate does not exceed 1000 degrees, so all in solid After the formation, due to the release of long-lived radioactive substances decay and gravitational potential energy, internal slowly warming, that the primitive earth contains iron is converted to liquid form, some iron oxides will also be   液态铁由于密度大而流向地心,形成地核(这个过程何时开始,现 在已否结束,意见颇有分歧)。由于重的物质向地心集中,释放的位能可使地球的温度升高约2000℃。这就促进了化学分异过程,由地幔中分出地壳。地壳岩石受到大气和水的风化和侵蚀,产生了沉积和沉积岩,后者受到地下排出的气体和溶液,以及温、压的作用发生了变质而形成了变质岩。  The liquid iron because of its high density and flow into the heart, to form the core (this process began when, now has not ended, have different opinions) Due to the heavy material to the concentration of released potential can make the earth's temperature is about 2000 DEG C This promotes the chemical differentiation process, separated by mantle Crustal rocks by weathering and erosion of air and water, the sedimentary and sedimentary rocks, the latter by the gas and solution discharged from the underground, the effect of temperature, pressure and metamorphism and the formation of metamorphic   这些岩石继续受到以上各种作用,可能经受过多次轮回的熔化和固结,先形成一个大陆的核心,以后增长成为大陆。原始地球不可能保持大气和海洋,它们都是次生的。海洋是地球内部增温和分异的结果,但大气形成的过程要更复杂。  These rocks continue to be above all, may be subjected to melting and consolidation of cycle times, to form the core of a continent, later to become the mainland The original earth may not keep the atmosphere and oceans, they are The oceans are the result of a moderate increase in the earth's interior, but the process of the formation of the atmosphere is more   原生的大气可能是还原性的。当绿色植物出现后,它们利用太阳辐射使水气(H2O)和CO2发生光合作用,产生了有机物和自由氧。当氧的产生多于消耗时,自由氧才慢慢积累起来,在漫长的地质年代中,便形成了主要由氮和氧所组成的大气。  The primordial atmosphere may be When green plants appear, they use the sun's radiation to make water vapor (H2O) and CO2 photosynthesis, resulting in the production of organic and free When oxygen is produced more than consumption, the free oxygen is slowly accumulated, in the long geological time, it formed the main nitrogen and oxygen in the

保护资源资源是有限的,随着我国工业生产快速发展,不要以为环境资源取之不尽,用之不竭。珍惜资源也成了造福于人类的一大举措。为此国务院颁发了一些法令,规划了我国5年到15年间的资源保护,标志着我国环境资源工作进入了新的发展阶段。目前,我国已经有9部以保护和节约土地资源为主的法制管理体系,为创建我们的资源保护意识奠定了坚实基础。我国为了保护环境资源,已建立如生态省生态示范区、“绿色学校”等各种设施。我国正在一步一步地迈向一条资源消耗低、环境污染少的道路上。需要我们重新连接人与自然的和谐。因为人类不珍惜资源,在人口不断增长的情况下,矿物、土地、淡水、森林、野生动植物等自然资源逐渐显现出紧缺的趋势。对于悲观派来说,资源是有限的,消耗一部分,就减少一部分;而可再生资源的再生总量也是有限的,承受不了日益增长的需求。资源也就成为经济增长的一个限制因素,最终要使经济增长停止下来。而乐观派则认为,由于技术进步,可利用自然资源的范围将不断扩大;人类工业对资源利用的效率将会提高,资源不足的局面总会改观。虽然他们讨论资源问题存在“矛盾”。但土地、淡水、森林等资源部分地区呈现出来的紧缺趋势不容忽视。它给这些地区的经济发展造成的困难是不言而喻的。但总而言之,资源确实是人类生活中不可小视的一部分。为了解决资源匮乏的危机,人类已经千方百计地从太阳能、水能、风能、生物能中寻找新的替代能源。但技术问题却是一大障碍,并且太阳能随昼夜、晴雨、季节的变化很大,难以成为大规模的工业能源,只能满足家庭以及一些特殊需要;水能增长的速度跟不上能耗增长速度,并对生态、生物链产生难以估量的影响。为此,人们正在致力于研究开发可控核聚变发电,人们对此寄于巨大希望,将它比作“人造太阳”,称之为“21世纪的人传给后代的纪念碑”。但需要我们重新连接人与自然的和谐。促进人与自然和谐,则需维护环境生态与人类生产工作和谐统一。人类的生产工作废气排放量大,资源的耗费也很严重,以污染环境和破坏生态来换取一时经济繁荣。环境生态创造的环境资源的丰富必然为人类的生产生活提供了坚实的原动力。因此,促进人与自然和谐,就要要求我们人类生产工作与环境生态的矛盾极速消减,在全社会树立起新的生态观,强力推进绿色科技技术,努力推进人们形成科学、节能、绿色、健康的生活方式,为生态文明建设和经济社会的发展提供精神动力、实际支持和科技保障,保持人类与自然的平衡、和谐。让我们一同保护好地球这个今日唯一可供生息的家园。
