+ 加入清单

家乡变了,真的变了!天空变暗了;小鸟变少了;小河变浑了,就连鱼虾都“躲”了起来。

家乡变的原因还是冒滚滚浓烟的烟囱和污水。这几年来,工厂不断的生产,废气从烟囱里冒出来,污水不断从管道里淌出来。还有就是人们乱堆垃圾,把地球的“外衣”破坏了。就这样,家乡被污染了。

小河在哭泣,哭泣自己没有伙伴;小鸟在呼吁,呼吁自己美好的家园;地球在痛苦,痛苦自己没了外衣;

我知道,原来家乡不是这样的。原来的家乡天是一片碧蓝,河是清澈见底,鱼虾自由自在,鸟儿成群飞翔。而现在呢?现在的家乡已不是昔日的家乡了,现在……

小鸟呼吁人类:人类,请你们不要把树木砍伐,让我们无家可归,四处流浪。我呼吁人类:请你们不要把垃圾四处乱丢,让空气变的浑浊,请你们为自己想一想,如果哪一天空气没了,你们会怎么样?

让我们一起保护自己的家园,不要让家园的环境再变难看,而要让家乡的环境变得更美!一起行动起来,为自己创造一片蓝天吧!

Everybody is responsible for environmental protection,. I accidentally caught a cold, do not know why, so he went to see the doctor, my mother asked the "flu?" Asked his mother.

The doctor shook his head, said: "because there are too many viruses in the air, is full of garbage, house dust, industrial emissions, and so on, these are the cause of poor air quality, virus." I seemed to understand a lot.

With the development of the society, living standards continue to improve, we drink the tap water, use the TV set, refrigerator, heater, elevators, etc. But in life, we constantly in the waste of resources, clean water, watering the flowers in the water, washing water, waste every day. Water for us to be of much use, irrigate farmland water, building water, plants and trees need water, and peoples life water for industrial water, we cant live without water. However, as we waste water was contaminated. If we use wash bowl of water to water the flowers and clean the water to wash clothes, wash your hands when the water is boiling down a little, that how much we want to save water. Electricity, as usual, we open a lamp less per person a day, watch less TV for an hour, less a elevator, how much we want to save electricity. When we are standing on the street, smell the stench, walking in the street is full of garbage, look up at the sky gray, one after another car emissions both in the exhaust, and people in disorderly cut down trees? Observe, to think of it, our environmental protection consciousness is so bad.

Nature cannot be improved, the life can choose to choose green, environmental protection, everybody is responsible for.

环境保护,人人有责。 我不小心感冒了,不知道是为什么,于是就去看了医生,妈妈问这“是流感吗?”妈妈问。

医生摇了摇头说:“因为空气中有太多的病毒,到处是垃圾,修房子的灰尘,工业排放的废气等,这些都导致空气质量差、病毒多的原因。”我似乎明白了很多。

随着社会的发展,生活水平不断提高,我们喝上了自来水,用上了电视机,冰箱,取暖器,电梯等。但生活中我们不断地在浪费资源:打扫卫生的水,浇花的水,洗衣服的水,每天都在浪费。水对于我们有多大的用处,浇灌农田要用水,修建房屋要用水,花草树木需要水,还有人们的生活用水工业用水等,没有水我们就无法生存。然而水在被我们浪费,被污染。如果我们用洗碗的水来浇花,洗衣服的水来打扫卫生,洗手时水开小一点,那我们要节约多少水。电也一样,我们每天每人少开一盏灯、少看一小时的电视,少座一次电梯,我们要节约多少电。当我们站在街上,闻到的是臭气,走在大街上到处是垃圾,抬头看天空灰蒙蒙一片,一辆接一辆的汽车都在排放着尾气,还有人在乱砍伐树木?注意观察,仔细想想,我们的环保意识实在太差了。

自然不可改良、生活可以选择 选择绿色生活、环境保护,人人有责。

How to develop low-carbon economy

There have been many environmental protection problems in recent years . One of the most serious problem is greenhouse gas emissions have caused climate change ,At the same time ,lots of trees have been used and wasted.So our earth is becoming warmer and warmer . .That brings us illnesses and death.

Luckily ,,many countries have done a lot to stop environmental pollution。Its the most important in the environmental protection today.

In my opinion ,on the one hand ,through education we should make people realize that destroying the environment means destroying ourselves,..On the other hand ,we should try to do something to produce fewer greenhouse gas emissions.

In a word .we must develop low-carbon economy....................

怎样发展低碳经济

现在这些年已经有很多关于保护环境的问题。其中最严重的一个问题就是温室气体排放已经造成了气候改变。同时,很多树木被砍伐掉了,而且大量别的资源已经被用完或者浪费。所以我们的地球变得越来越温暖(热)。这样带给我们的是疾病和死亡。。

幸运的是,很多国家已经采取了很多措施来控制环境污染问题。如今,这是最重要保护环境的措施。

我认为,一方面,虽然教育我们应该让人们意识到破坏环境就是伤害人类自己。另一方面,我们应该尽力做一些事情来控制温室气体增长。

总之,我们必须发展低碳经济。。。

人类一直以为地球上的所有资源都是取之不尽的,没有担心过自己所做的一切是否会对地球造成伤害,从不担心把千万吨废气送到天空去,又把数以亿吨计的垃圾倒进海洋。大家都认为世界这么大,这一点废物算什么?我们错了,其实地球虽大,但生物只能在海拔8千米到海底11千米的范围内生活,而占了95%的生物都只能生存在中间约3公里的范围内,人竟肆意地从三方面来弄污这有限的生活环境

海洋污染:主要是从油船与油井漏出来的原油,农田用的杀虫剂和化肥,工厂排出的污水,矿场流出的酸性溶液;它们使得大部分的海洋湖泊都受到污染,结果不但海洋生物受害,就是鸟类和人类也可能因吃了这些生物而中毒。

陆地污染:垃圾的清理成了各大城市的重要问题,每天千万吨的垃圾中,好些是不能焚化或腐化的,如塑料、橡胶、玻璃、铝等废物。它们成了城市卫生的第一号敌人。

空气污染:这是最为直接与严重的了,主要来自工厂、汽车、发电厂等等放出的一氧化碳和硫化氢等,每天都有人因接触了这些污浊空气而染上呼吸器官或视觉器官的毛病。我们若仍然漠视专家的警告,将来一定会落到无半寸净土可住的地步。

环境污染是指人类直接或间接地向环境排放超过其自净能力的物质或能量,从而使环境的质量降低,对人类的生存与发展、生态系统和财产造成不利影响的现象。具体包括:水污染、大气污染、噪声污染、放射性污染等。水污染是指水体因某种物质的介入,而导致其化学、物理、生物或者放射性污染等方面特性的改变,从而影响水的有效利用,危害人体健康或者破坏生态环境,造成水质恶化的现象。大气污染是指空气中污染物的浓度达到有害程度,以致破坏生态系统和人类正常生存和发展的条件,对人和生物造成危害的现象。噪声污染是指所产生的环境噪声超过国家规定的环境噪声排放标准,并干扰他人正常工作、学习、生活的现象。放射性污染是指由于人类活动造成物料、人体、场所、环境介质表面或者内部出现超过国家标准的放射性物质或者射线。例如,超过国家和地方政府制定的排放污染物的标准,超种类、超量、超浓度排放污染物;未采取防止溢流和渗漏措施而装载运输油类或者有毒货物致使货物落水造成水污染;非法向大气中排放有毒有害物质,造成大气污染事故,等等。

随着科学技术水平的发展和人民生活水平的提高,环境污染也在增加,特别是在发展中国家。环境污染问题越来越成为世界各个国家的共同课题之一。

由于人们对工业高度发达的负面影响预料不够,预防不利,导致了全球性的三大危机:资源短缺、环境污染、生态破坏.人类不断的向环境排放污染物质。但由于大气、水、土壤等的扩散、稀释、氧化还原、生物降解等的作用。污染物质的浓度和毒性会自然降低,这种现象叫做环境自净。如果排放的物质超过了环境的自净能力,环境质量就会发生不良变化,危害人类健康和生存,这就发生了环境污染。

环境污染会降低生物生产量,加剧环境破坏。

环境污染源主要有以下几方面:

1)工厂排出的废烟、废气、废水、废渣和噪音;

2)人们生活中排出的废烟、废气、噪音、赃水、垃圾;

3)交通工具(所有的燃油车辆、轮船、飞机等)排出的废气和噪音;

4)大量使用化肥、杀虫剂、除草剂等化学物质的农田灌溉后流出的水。

5)矿山废水、废渣。

珍惜我们共同的家园,爱护地球的环境,减少对环境的污染,从你我做起!

尊敬的校领导:

你们好!

我是六年级的一名学生,在这个多姿多彩的学校里学习、生活已有两年之久。校园是授予我们知识、赋予我们欢乐的地方,在干净整洁的校园里学习生活的学生都感到很快乐,这里有我们的小伙伴,我们一起学习、玩耍,每天的广播播放着我们身边的有趣的事,让我们知道了一些科学小常识和许许多多的课外故事。学校里不时地开展一些有意义的课外活动,我们都很积极参与。每当我们走近校园,优美的校园景色让我们感到无比的舒心和愉快。有长方形花坛、大树的枝叶无比茂盛、小草生机勃勃、富有活力,这些不仅美丽、葱郁,给学校增添了不少活力。

可是今天却躺着一大片的枯枝败叶,那些枯枝败叶上还不时伴着一个个报废的垃圾袋、食品袋,咀嚼完后随地乱吐的口香糖随处可见,地上散落着的树叶片、草根都是一些淘气的同学们的佳作。还有被塞到各个角落的看不见的垃圾,美丽的校园变成一个遍地垃圾的“垃圾场”!

为了能让我们的校园恢复以往的美丽,我向学校提出以下建议:

1、继续开展“争当绿色环保小卫士”的活动,主要向在校学生宣传环保活动、呼吁环保,纠正同学们乱丢乱扔垃圾的恶习。

2、通过广播电视节目里播一些环保小常识,让同学们认识到浪费资源、污染环境是在污染我们自己生活的环境,从而自愿加入到保护环境的行列中来。

3、加强校园环境管理,不随意丢弃乱扔,对爱护环境、不乱抛撒废弃物的班级进行适当的奖励,对危害环境、破坏植被行为作出合理的批评。

希望校领导能在百忙之中抽空看一看我写的这份环保建议书,采取我的一些建议。我衷心希望我的这份建议书能为学校的环保作出一份贡献。

祝:工作顺利,身体健康!

作文【一】

One day Sun Wukong together with his master and brothers was walking across a river. Suddenly his master fell off the horse by the bad smell of river water. They found the water so dirty that they could hardly breathe.

A lot of factories along the river always poured their waste water and rubbish straight into the river which made the river water polluted. In this way most of the fish in the river were killed. If the river water all over the country is polluted like this, no living things will exist in the water. Now more and more people have come to realize how serious this problem is. Our government is doing her best to take measures to fight against pollution. We expect that the water in every river will be made cleaner and cleaner before long.

作文【二】

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.

To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

作文【三】

Dear editor,

Environmental problems are becoming more and more serious all over the world. _________________________________________________________

Yours truly

Li Hua

Dear editor,

Environmental problems are becoming more and more serious all over the world.

With the development of industry and agriculture, cars make great noises and give off poisonous gas. Because of population expansion and overdevelopment, resources has become less and less. Trees on the hills have been cut down, and waste water is being poured continuously into rivers. The whole ecological balance of the earth is changing. Massive destruction of environment has brought about negative effects and even poses a great threat to man’s existence.

We must face the situation that exists and take actions to solve our environmental problems. We hope that all these measures will be effective and bring back a healthful environment.

There are still many environmental protection problems in recent years. One of the most serious problems is the air, water and soil serious pollution. Air pollution seriously damage peoples health. Polluted water causes diseases and death. Whats more, vegetation has been greatly reduced, with the rapid growth of modern cities.

In order to protect the environment, governments in many countries have done a lot of work. This paper introduces the legislative measures to control air pollution, to protect forest resources and Marine resources, to stop any environmental pollution. Therefore, governments are play a most important function of the environmental protection today.

I think, in order to protect the environment, the government must take more concrete measures. First of all, the government should let people fully realize the importance of environmental protection, through education. Second, more efforts should be made to put the population planning policy, because more people means more people means more pollution. Finally, those who intentionally damage the environment should be punished severely. We should let them know that destroying environment means destroying mankind themselves.

仍然有很多环保问题在近几年。最严重的问题之一是空气,水和土壤的严重污染。污染的空气严重损害人们的健康。污染的水引起的疾病和死亡。更重要的是,植被已大大减少,随着现代城市的快速增长。

为了保护环境,许多国家的政府都做了很多工作。介绍了立法措施控制空气污染,保护森林资源和海洋资源,制止任何环境污染。因此,各国政府正在发挥环保今天最重要的作用。

我认为,为了保护环境,政府必须采取更具体的措施。首先,政府应该让人民充分认识到环境保护的重要性,通过教育。第二,更应努力把人口规划实施的政策,因为更多的人意味着更多的人意味着更多的污染。最后,那些故意破坏谁应该受到严厉惩罚的环境。我们应该让他们知道,破坏环境就是毁灭人类自己。

篇12:环境污染原因环境污染的根源

在十年前的中国,大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样,看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产,燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝,随着中国经济的迅速发展,人们生活水平的不断提高,人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题,其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬,专家们各有其立场,但对于普通百姓来说,全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖,海平面上升,冰川融化,动植物灭亡的问题,人们大多数是在电视新闻或报刊杂志上看到,恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题,人们开始关注更多的便是最近发生在北京,广州,武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康,更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象,国外专家学者很多年前便开始研究。

那么何为灰霾?灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物(PM2.5)和臭氧()、二氧化氮()、二氧化硫()、挥发性有机物()等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关,还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种,直径小于2.5微米的颗粒物(PM2.5)和直径小于10微米的颗粒物(PM10)。虽然两种形式的颗粒物都对人类健康有极大的危害,PM2.5被普遍认为是更危险的,因为它的体积小,大约只有人类头发宽度的1/30。人们在呼吸时,PM2.5可以进入人类肺组织深处,甚至进入血液,造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此,PM2.5可以传播的更远,停留在空气的时间越长,影响更大的人口。PM2.5和PM10的主要来源包括机动车,电厂和其他工业源,以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合,可以在城市或农村地区天空一片阴霾,而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因,像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围,当地空气干燥,白天阳光充足。到了晚上,地表面冷却很快。地面附近的空气变冷,而上层空气都比较热,形成逆温。北京市位于华北平原的西北边缘,背靠太行山余脉和燕山山脉,面对辽阔的华北平原,东南距渤海约150公里, 地处暖温带半湿润地区,气候属于暖温带半湿润大陆性季风气候,四季分明,春季多风和沙尘,夏季炎热多雨,秋季晴朗干燥,冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远,周围地形如盆地,集热容易散热难,河湖多、晚上水汽多,城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市,而且城市海拔较低,周围至少有一面是高地,都分布在低于南北纬50度的地方。这些地区夏季阳光明媚,天气温暖干燥。在城市的盆地地区,逆温现象十分普遍。夏季的阳光使地面温度升高,城市街道和建筑物迅速升温,与炎热的物体表面接触的空气温度升高。通过对流空气向上运动,但它却不能穿透逆温层,因为上面的空气温度更暖且密度更小。空气聚集,但连续的对流形成了垂直的循环,使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下,通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集,大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响,学者称它为街谷模型。随着城市化的加速,城市及城市周边的自然生态系统逐渐被人工生态系统取代,取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续,高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时,风速迅速降低并产生特殊的湍流,使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用,因此,对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市,尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物(PM)浓度和40%的二氧化氮(NO2)浓度。因此,通过对植被的合理利用能过创造一个有效的城市污染过滤膜,对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题,相反它是一个长久的问题,从它如何形成,加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象,它只是地球环境污染的一个缩影。我们更应该探究它的根源问题,什么才是它形成的根源,什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题,但我们可以通过减少排放源,通过增加植被,加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼,越来越发达便利的交通,相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了,人们是否会怀念那晴朗的蓝天,向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

The earth is the mother of mankind, the survival of mankind cannot leave her. Earth has taken a knock. How can we stand? He said my house on the west side of the river! Previously, the stream on the bottom, there are a lot of fish, shrimp swimming freely in it, all day live a carefree life, the river is full of vitality. At that time I like to play there. Now, because of the big cities site random discharge of sewage, and people are constantly littering. Disappeared, the vibrant river became a smelly sewage river, I dont like it!

Nowadays, many wild animals become a plate of food. Without these lovely animals, our life will become special boring. Rose up in the morning, cant hear the birds chirping and crisp sound, that is bad!

Patches of forest became less factories. The lawn into a wasteland, beautiful grassland into desert. Why is this? This is because people caused by deforestation.

Human survival depends on the environment, the environment depends on human protection. Do humans have that moment didnt wake up until the end of the earth? I call on: to protect the environment! We act together.

地球是人类的母亲,人类的生存离不开她。地球受到了破坏,我们又怎么能袖手旁观呢?就说我家西边的小河吧!以前,这条小河清澈见底,有很多小鱼小虾在里面自由自在地游着,整天过着无忧无虑的生活,小河里充满了生机。那时我很喜欢到那里玩。现在,由于大城市的工地随意的排放污水,还有人们不断的乱扔垃圾。那条生机勃勃的小河不见了,变成了一条臭烘烘的污河,我再也不喜欢那里了!

如今,许多野生动物成为了人们盘中的美食。如果没有这些可爱的动物,我们的生活就会变得特别无趣。早晨起来,不能听到小鸟叽叽喳喳清脆的叫声,那多不好啊!

片片森林变成了座座工厂。草地变成了荒原,美丽的草原变成了沙漠。这究竟是为什么?这是因为人们乱砍乱伐造成的。

人类要靠环境生存,环境要靠人类保护。难道人类还要等到地球毁灭的那一刻才醒悟吗?我呼吁:保护环境!大家一起行动吧。

如今的地球姑娘已经是头发稀疏,脸儿黄黄,衣服脏脏。树木大片砍伐,江和污染,这一切实在太严重了!所以,我为地球姑娘想了一个装扮她的好方案,使她能在宇宙千年选美大赛中获得冠军。

方法一:增加头发。把树苗栽进地球姑娘的头上,每年都要加以保护,春天、夏天喷撒防虫剂,不能让可恶的虫子破坏树苗,更不能让人们滥砍滥伐。这样十几年后,小树苗长成绿绿的大树,地球姑娘的头发又长起来了。

方法二:改变地球姑娘肤色。多种植绿草,把大片沙漠变成绿洲,这样沙尘暴军队就不会出现了,地球姑娘黄黄的脸蛋又变得好看。

方法三:穿漂亮衣服。赶快把脏脏的衣服脱下,穿上漂亮衣服。怎样换呢?看那城市乡镇,高高耸立在烟囱每天喷放着“灰色病毒”,大小工厂的排污管,每时都排放着污水。这是地球姑娘受到损害的主要原因,要彻底根除这些污染,让天空变蓝,河水变清。鸟儿尽情地歌唱,鱼儿自在地游泳。地球姑娘穿上最美丽的衣裳。根据我的这些方案,地球姑娘在宇宙千年选美大赛中准能获得冠军环境污染治理作文作文。

Directions:For this part, you are allowed 30 minutes to write a composition on the topic:

Pollution: An Increasing Concern in China You should write at least120 words following the outline below in Chinese.

1. 中国的污染的现状

2. 造成污染的原因

3. 解决的办法

Pollution: An Increasing Concern in China

It is reported that ten big cities in China are being ranked among the top twenty cities with the highest pollution index in the world. This means it is high time we did something to bring the situation under control.Many factors are contributing to the deteriorating situation: industrial wastes pumped into the air, the lakes and rivers; a increasing number of automobiles crowding into the streets; the widespread use of plastic bags etc.

To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. What’s more, the media should play an important role in implanting a sense of environmental consciousness into people’s mind. If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.

Everyone should protect the environment, this is the law of nature, if not protect the environment, the world will be contaminated.

To protect the environment from every bit of small start, and I have not done well. Have a New Year, we went to shun feng mountain park, riding a bicycle, we were hungry, we bought a small bag of snacks to eat, while I, eat snacks, I happy too much because it is over, so casually took me to once eat 7 packet snacks packaging thrown on the ground, and then I went in a convenience store in watching TV, while todays TV is very good-looking, half an hour later, I put the mother with all I said before, all my thoughts are indulged in the drama. After 30 minutes, I didnt think of it, but, at that time, his mother angry of say: "you this smelly wenches, didnt I tell you before to protect the environment, you forget?" I said: "Im not forget, I just from watching TV." Mother said: "some important watching TV, or picking up litter some important?" I said: "rubbish." Mother said: "you hurry up to pick up."

And then, I picked up a small pile of junk, throw in the trash, I apologized to his mother not only, I also to shun feng mountain park, sweep the floor every aunt to recognize the fault. Because, if everyone throw a piece of garbage on the ground, and then will add burden to clean the aunt. If you see a piece of garbage on the ground, then you are curved waist, and activities, do a man to protect the environment, is to clean the aunt to reduce burden...

, although it has been over the past year, I learned about it, if the world all throw a piece of garbage on the ground, the whole earth will become a waste, so each of us should protect the environment, protect the earth, the world will be more beautiful!

人人都要保护环境,这是大自然的规律,如果不保护环境,世界就会被污染。

保护环境是从一点一滴的小事做起,而我却没有做好。有一次过新年,我们去顺峰山公园游玩,骑完自行车,我们个个都饿了,我们买了一小包零食来吃,而我,吃完零食,我因为高兴过头了,所以随手就把我吃过的7包零食的包装扔在地上,然后我进去便利店里面看电视,尽管今天的电视剧很好看,过了半个小时,我把以前妈妈跟我说的话忘得一干二净,我所有的心思都沉迷在这个电视剧里面。在过了三十分钟,我才想起来,可是,这时候,妈妈生气的走过来说:“你这个臭丫头,难道我以前跟你说的要保护环境,你都忘了吗?”我说:“我不是忘了,我只是顾着看电视。”妈妈说:“看电视重要一些,还是捡垃圾重要一些?”我说:“捡垃圾。”妈妈说:“那你快点捡呀。”

然后,我捡起一小堆垃圾,扔进垃圾桶,我不但向妈妈认错了,我也向顺峰山公园的每一个扫地阿姨认了错。因为,如果每个人都扔一块垃圾在地面,那么就会给清洁阿姨增加负担。如果你看见一块垃圾在地面,那你就弯弯腰,动动手,做一个保护环境的人,那么就会给清洁阿姨减少负担……

虽然这件事已经过去一年了,但是,这件事让我学会了,如果世界上都扔一块垃圾在地面,那么整个地球就会变成一片废区,所以我们每个人都要保护环境,保护地球,世界才会更美好!

Dear John,

Im glad to hear from you. Now let me tell you something about our city. Nantong is trying to set up a national civilized city. We middle school students are also doing some things for it. We are all polite to our teachers. (In class, we listen careful to them./When we meet them, we always say hello to them./…)We also respect the old. For example, we help them cross the streets.

We are always ready to help each other.(When one has difficulty with his studies, others will help him at once./...)We often show our love to those in trouble. Last month, the students of my class donated money to the earthquake-hit areas.

Besides, we plant trees to protect the environment and make our city more beautiful.

Nantong is my hometown. I will do my best to turn Nantong into a civilized city.

篇20:污染环境建议书

全文共 953 字

+ 加入清单

环保局长:

如今十分发达的地球,虽然环境情况看起来十分乐观,但是却有十分重大的隐患,这都是人为制造出来的,大肆砍伐树木、建立化工厂、胡乱排放有害液体。“对人类威胁较大的气体,世界每年的排放量达6亿多吨。。。。。估计到下个世纪中叶,地球表面有三分之一的土地面临沙漠化的危险,每年有6平方公里的土地沙漠化,威胁着60多个国家。。。。。”看见这一组组令人触目惊心的数字,人类,你们有何感想?从2300万年到1800万年前森林古猿的出现到现在人类高度发达的文明时代,对于每个人从未停止过的索取,大自然都是“有求必应”的,这更滋长了人类的贪欲。

举一个例子:我国的木兰溪,在50年代初本是一个清澈见底的河流,但现在它已是鱼虾绝迹的污河,又为我们的地球母亲添多一道疤痕。这,不是给人类重重地敲响了警钟吗?

由此,我郑重地向仍未觉悟的人们建议:

第一,人类要想征服可怕的大自然,就必须尊重自然。对于改造自然理应慎之又慎,又要大刀阔斧,勇于实践和改良,才能控制自然,使自身利益与自然协调发展,决不能重蹈西方发达国家“先污染,后治理”的覆辙。

第二,要从我做起,首先选择有利于保护环境的生活方式。善待我们的家园、善待地球,共创一个美好的生活环境。

1。节约资源减少污染

(1)节水为荣,随时关上水龙头,防止滴漏。

(2)慎用清洁剂,尽量用肥皂,减少洗涤剂中的化学物质对水的污染。

2。绿色消费环保选择

(1)用无铅汽油、无镉铅电池、无磷洗涤剂,减少水与空气的污染。

(2)购买低砩家用制冷器具、无砩发用摩丝,减少对臭氧层的污染。

3。重复使用多次利用

尽量少使用一次性用品,多使用耐用品。如不使用一次性塑料和餐盒,减少白色污染;不使用一次性筷子;自备购物口袋或提篮。

4。分类回收循环再用

不乱丢弃废电池、废塑料等垃圾、废物;将垃圾分类投放,变废为宝,使资源循环再生,造福人类。

5。保护自然万物共存

不猎杀、使用珍稀动物和受保护的动物,关爱与保护野生动植物;植树造林,爱护我们身边的每一寸绿地、每一株花草、每一片树木。

6。讲究卫生保护环境

不随地吐痰,不乱扔垃圾,不在公共场所吸烟,不制造噪音。

作为新时代的小学生,我倡导同学门提高保护环境的意识,也建议叔叔阿姨们加入我们的队伍中来,为保护环境、造福后代贡献自己的力量。因为:保护环境,刻不容缓!
