Air pollution is one of the major problems of the modern world. A great deal of energy is needed to run the factories of modern industrial nations.
现代社会空气污染的.一个主要的原因是,现代工业园区的工厂需要大量的能源。
Automobile, trains, planes and busses need energy, too. Nearly all of this energy is produced by burning fuels. The burning produces wastes, some of which remain in the air, causing air pollution.
汽车、火车、飞机和公共汽车都需要能量,几乎所有的能量通过燃烧燃料产生,燃烧产生的废汽造成空气污染。
Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities.
科学家们正在寻找阻止空气污染的方法,尤其是在大工业区和人口稠密的城市的。
They are studying new ways of generating electricity that may be less damaging to the environment. In the meantime, many power plants are being modernized to give off less polluted material.
他们正在研究发电的新途径,可以减少对环境的损害.与此同时,许多发电厂正在实现现代化以减少污染物质.
Also, engineers try to design and locate new power plants to do minimum damage to the environment. However, it may be that we still have a long way to go before we have a "clean" world. Nearly all of the countries are trying hard to prevent and control air pollution.
同时,工程师们尝试和找到对环境的损害最小的新型能源。然而,在我们有一个“干净”的世界之前我们还有很长的路要走。几乎所有的国家都在努力预防和控制空气污染。
There indeed seems to be no end to tasks that environmentalists will be required to do. People will continually find new ways to control pollution.
看来环保主义者要做的任务乎没有尽头,人们会不断地寻找新的方法来控制污染。
Pollution is becoming more and more serious all over the world. As is shown in the cartoon, two cars are giving off waste gas and three people are trying to avoid breathing in the poisonous gas by masking their face with their hands. The poisonous gas sent off by factories, domestic appliances and automobiles has made the air unhealthy for people to breathe.
There is no denying that automobiles are indications of civilization, progress and development; nevertheless , automobiles cause the serious problem of air pollution. Scientists have warned that unless effective measures are taken, the problem of pollution will eventually get out of hand. Actually, people are showing a real concern over the problem. For example, there is an increasingly loud voice from the public for firm action against pollution from automobiles.
Indeed, the earth is our home and we have the duty to take care of it for ourselves and for our descendants. In my opinion, we should work out concrete solutions to the problem of pollution from poisonous gas given off by automobiles. For example, the automobiles should be equipped with a device which can dispose of waste gas so as to prevent it from polluting air. Only in this way can we really solve the problem of air pollution caused by automobiles.
污染是越来越严重的世界各地。这幅漫画所示,两辆车散发废气和三个人正试图避免吸入有毒气体,掩盖自己的脸用手。工厂的有毒气体被罚下,家用电器和汽车污染的'空气影响了人们的呼吸。
不可否认,汽车文明的迹象,进步和发展;然而,汽车造成空气污染的严重问题。科学家们警告说,除非采取有效措施,污染的问题最终会失控。实际上,人们展示一个真正的担忧这个问题。例如,有一个越来越大声对汽车污染公众公司行动。
事实上,地球是我们的家园,我们有责任照顾它为我们自己和我们的后代。在我看来,我们应该找出问题的具体解决方案的有毒气体污染的汽车。例如,汽车应该配备一个设备可以处理废气,以防止污染空气。只有用这种方法我们才能真正解决由汽车引起的空气污染的问题。

Air pollution comes from factories, power stations and cars. Chemicals in the smoke from power stations cause a lot of damage. They can travel hundreds of miles in the wind before falling to the ground in the rain. But this "chemical rain" gradually destroys trees in the forests and kills fish in the lakes. In Germany, over 50% of the country's trees had been damaged by the year 1986.??? Time and time again there are serious accidents that pollute the air.? In 1986 there was a bad accident at a nuclear power station in Russia.? A cloud of radiation crossed the whole of Europe. It is said that 125,000 people died in Russia as a result of illnesses caused by this accident.In 1984 there was a serious accident at a factory in India and a cloud of dangerous gas covered the town of Bhopal. Over 2,500 people were killed that night, and hundreds of thousands of people were injured.? Many of the injured lost their sight.
This year, with the high speed development of economy in our country, the improvement of peoples living standards. In this environment, the deterioration of ecological environment is gradually in our country.
In the case of priority to the development of the economy. But at the expense of the environment. We are in urgent need to change the status quo. In the past, in order to develop the economy, our countrys forest area is not reduced, cut down trees. Soil and water loss. Desertification is expanding fast. Amidst the city, and farmland. Every spring, Beijing sandstorm struck by the Mongolian plateau. PM2.5 table. Chemical companies in order to save costs, will not be processed into the river sewage, and makes the water undrinkable. Now almost impossible to find not polluted river in China.
We should realize the seriousness of the problem now. Effective measures must be taken. First, change ideas, should pay more attention to environmental protection. Should the economy and environment simultaneously. Now in China is taking measures to change the status quo. In the second. , through legislation, our country has now been made in the history of the most severe "environmental law" in the third, the governments regulation. Environmental protection bureau should really law enforcement. I believe our country environment will get better.
过去,人们不必担心保护环境的问题。
因为那时地球上人口稀少,自然资源似乎取之不尽。
如今,一切都改变了。世界变得拥挤异常。我们正在耗尽我们的自然资源,有毒化学制品的使用也正污染着环境。如果我们继续这样下去,地球上的生命将不复存在。
我们都知道如果从海里捕捉太多的鱼,海里就不会再有鱼了。但是,现代化的捕鱼技术使得捕鱼量越来越大。我们都知道如果砍伐太多的树木,森林就会消失。但是,我
们仍旧使用强大的机械砍伐越来越多的`树木。我们都知道如果河水被废弃物污染的话,我们只有死路一条。但是废弃物仍然源源不断地进入河里
我们知道,人口继续照现在这个速度增长的话,不出几年,就会发生食物短缺。我们该如何解决这些问题呢?
如果我们多吃蔬菜,少吃肉类的话,我们就会有更多的食物。因为同样大小的土地如果种庄稼的话会比养殖动物多养活五倍多的人。
如果我们学会再利用的话,自然资源就能持续更久。
如果人们使用现代化的生育控制方法,世界人口就不会增长如此迅猛。
最后,如果我们能够教育人们都意识到这些问题的话,未来我们就会有一个更好、更洁净的星球。
Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.
Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.
We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are
still put into rivers.
We know that if the population continues to rise at the present rate, in a few years, there won't be enough food.What can we do to solve these problems?
If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycie them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.
空气污染不管是对我们还是对植物危害都很大,为什么这么说?这是我通过一次研究发现的,至于是什么研究,就听我慢慢跟大家说。
在庭园里种些花草,不仅能美化我们的家,还能净化我们四周的空气,让我们呼吸的空气更清新。因此有人说,一个具有一定规模的庭园就像一个不停工作的天然“氧吧”,能提供我们所需的清新空气。但*几天我发现我家的天然“氧吧”“*”了,每天清早我到院子里,再也呼吸不到以前那种清新的空气了。这是怎么回事呢?是什么令到我家的天然“氧吧”停止工作呢?我下定决心,一定要把那个“凶手”揪出来!
针对上述事件,我查阅了大量资料,综合我对花草、树叶的连日观察,发现嫌疑最大的是*日车辆的频繁来往,造成了严重的空气污染,加上附*的一些食店排放出来的油烟因*日风势不强,得不到有效的散解,被花草、树叶过量地吸收,造成叶片表面气孔被尘粒堵塞,以至它们不能“工作”。我咨询了自然老师,老师认为这种可能性很高,让我回家去试验一下。于是我回去采了一些花草样本,把它们栽在室内,定期让它们照射阳光,浇水次数加密,几天后,和其他的比较一下,发现经我“悉心照顾”的那些花草比外面的生长得好多了。根据我的实验结果,我把每天浇水的次数加密到每天3次,经过我一个多星期“苦心经营”,“天然氧吧”终于又恢复了正常的'工作,每天为我们提供着清新的空气。
综合以上所述,我得出了结论:“天然氧吧”的停止工作,是因为周围空气污染的日趋严重,使花草过量地吸收了空气中的一氧化碳、碳氢化合物、氮氧化物以及空气中的悬浮粒子,以至花草、树叶中用于进行光合作用的气孔被堵塞,机能超荷,停止工作。我终于把这个“凶手”揪了出来!
你看,这就是空气污染的危害。空气污染其实伤害的不仅仅是我们自己,也伤害了地球上的许许多多的生物,还有我们的地球母亲……让我们一起行动起来,减少空气污染,一起保护我们的生存环境吧!
现在,空气污染是一个很让人头疼的问题,我的家乡临汾就是一个空气污染很严重的城市,我为我的家乡的环境感到很揪心。
其实,空气污染的主要原因有汽车尾气、燃烧物品、开采矿产等。最为严重的就是开采矿产。大部分城市都有一些矿产资源。在提炼过程中,会产生一氧化碳、总悬浮颗粒物、二氧化硫等对人类健康有害的物质。汽车尾气的危害是大家都知道的,但用较洁净的天然气燃烧,也会产生二氧化碳,使气候变暖。长期生活在空气被污染的环境下,会引发哮喘、喘鸣等疾病,危害生命。
我的家乡临汾,以前曾有“花果城”的美称。可现在“花果城”变成了以“脏、乱、差”闻名的城市。就是因为过多的挖煤、炼钢、发电。20xx年,河西电厂向市区排放了2万多吨粉尘颗粒物、2600多吨二氧化硫。这还只是一部分。还有一个“最魁祸首”是开采煤矿、铁矿。因为开采煤矿、铁矿会产生总悬浮颗粒物、二氧化硫。
我自己也深有体会。每天早晨起来,大多看到的都是灰蒙蒙的天空以及飞扬的尘土。太阳每天出来的时间也推迟到了9点30分。我都不敢穿浅色衣服,因为假如穿浅色衣服的话,回家后衣服上可以“堆尘土人”了;放学回家后,必须要擦一遍桌子,才可以写作业,不然作业就会穿上“尘土外衣”了;吃完饭如果把剩下的菜放在桌子上,那么菜就会盖上泥被子……
临汾正在治理中,我相信临汾一定可以拾回它以前的“花果城”的称号。虽然这个过程不知道会有多久,但是我很有信心,我的家乡一定可以回到我心目中的样子,那是一个天蓝气清,没有污染的美丽的花果之乡。
周六上午,我和爸爸妈妈一起骑车感受一下濮阳市的空气质量。虽然天气寒冷,但我也感觉不到冷,因为我要做一次小小的空气调查员。
一路上我们有说有笑,当走到黄河路西段时,一股难闻的气味扑鼻而来。我便问爸爸:“爸爸,这是什么气味呀,这么臭。”爸爸对我们说:“这里是我市的化工厂区,化工厂产生的废气气味。”
爸爸妈妈又带我来到马夹河边,看到河水的颜色发黑,并有一阵阵的恶臭,我问爸爸:这是为什么呢?爸爸给我讲:这是因为化工厂的污水和家庭的废水排向河流的缘故。
现在的空气污染太严重了,化工厂产生的废气,家庭的废水不经过处理直接排向空中和河流,汽车、摩托车等机动车数量迅速增加,尾气排放量加大。由此造成严重的空气污染。
为了缓解空气污染,请大家从身边的小事做起,不要乱扔垃圾,不要在野外烧火,尽量不要用尾气排放量高的.汽车……相信有了大家的支持,空气污染造成的危害一定会消失!
In general, there are two ways of traveling, private cars and public transportation. Chinese people should regard public transportation as their first traveling opinion.
一般来说,有两种旅游方式,私家车和公共交通工具。*人应该把公共交通工具作为旅游的第一选择。
First, there are so many people living in this countries that make it so crowded. If each chinese people own a car, there will be far more traffic jams and accidents, which increase you impatience.
首先,这个国家住着很多人,使得它非常拥挤。如果每个*人都拥有一辆私家车,将会有更多的交通堵塞和事故,这会让你变得更加的不耐烦。
Moreover, there will be far more pollution resulted from cars. Once a car started, it release huge amount of dirty gas and heat, which lead to great pollution and result in green house effect.
再者,由于私家车将会有更多的污染。一旦汽车起动,它释放大量的脏气和热量,这会导致很大的污染和温室效应。
All in all, Chinese people should take public transpotation into consideration first。
总之,*人应该以公共交通工具为第一选择。
In recent years, banning fireworks in a large number of Chinese cities has aroused a heat discussion among the public. Some are against it while some are for it. As far as I am concerned, banning fireworks is necessary and advantageous.
*年来,在*许多大城市都有禁止燃放烟花的政策,这一禁令已引起社会大众的热烈讨论。有些人支持也有人表示反对,我认为禁止燃放烟火是很有必要且有益的。
There are a few points accounting for my view. First, banning fireworks is good for keeping air quality. Setting off fireworks is one of the sources of air pollution because it will produce a lot of sulfur dioxide and other hazardous gases, which may lower air quality if they are emitted unlimitedly. Second, banning fireworks is helpful for people’s health. The hazardous gases from setting off fireworks are a potential harm for people’s health because these gases are the causes of some serious disease like respiratory diseases. Besides, fireworks are also a threat for people. The explosion of fireworks is so fast that people will be hurt without awareness. In addition, setting off fireworks will produce noise, which has a negative influence on people’s health and life.
我的理由有如下几点。首先,禁止燃放烟火有利于保证空气质量。燃放烟火是一大空气污染的来源,因为燃放烟火会释放出大量的二氧化硫和其他有害气体, 如果这些有害气体不能得到控制将降低空气质量。其次,禁放烟火有助于人们的身体健康。燃放烟火而释放出的有害气体对人们的身体健康有潜在危害,因为这些有害气体会导致人们患上严重的疾病,例如呼吸道疾病。另外,烟火还会威胁到人们的安危。烟火燃爆十分迅猛,无警觉的人们常常会受到伤害。最后,燃放烟火爆竹会产生噪音,会对人们的身体健康和日常生活带来负面影响。
For above reasons, I consider that banning fireworks is advantageous. In addition, I think that other healthy and meaningful ways of celebrating festivals should replace setting off fireworks.
综上所述,我认为禁止燃放烟火是十分有利的。此外我想应该有比燃放烟火更好、更有意义地庆贺方式。
The cartoon presents the Earth with a personified human face that seems quite unhappy. A examination of the picture immediately reveals that the source of its mood is the air pollution resulting from a huge number of automobiles spread around its surface.
The cartoon, no doubt, aims at alarming humans of the heavy load we have exerted on Earth by our insatiable production and usage of automobiles. However, the majority of people merely indulge in the celebration of the convenience brought by cars, while forgetting or sim* neglecting their harmful impact on the atmosphere. Admittedly, there are various factors contributing to the current worldwide air pollution, but it is undeniable that the exhaust from automobiles is categorized as one of the major elements. I would like to make the following proposals to solve this problem: firstly, we should ap* the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. It should also be guaranteed that the clean energy be inexpensive so that it can be widely accepted. Besides, there should be attempts to develop possible transportation means, so that citizens can be diverted from dependence on cars. In short, it is humans‘ responsibility to resume clean air for Earth.
空气污染的建议书
在快速变化和不断变革的新时代,越来越多人会去使用建议书,建议书是就某项工作提出某种建议时使用的一种常用书信,也叫意见书。你写建议书时总是没有新意?下面是小编整理的空气污染的建议书,欢迎大家分享。
罪恶的人类:
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*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!
尊敬的*:
您好!
我是济南市的一名小学生。济南是历史名城,山美水秀,72名泉享誉中外,被称为"泉城"。但是,也有许多不尽人意的地方,我谨去信向您指出济南市的不足之处,并提出改进的建议,供您参考。
济南南部是秀丽的山区,北部是黄河的滩区,地势的特点造成了济南空气流通不畅,再加上济南最*几年空气污染严重,因此,济南的空气质量在全国47个重点城市中一直排在倒数第一!您还记得9月26日的那场狼烟吗?那天泉城弥漫着烟雾,能见度极差,人连10米内都看不清,引起道路堵塞和多起车祸,飞机更是没法起飞,民航山东空管分局局长说:"因为跑道能见度低于350米的起飞标准,有12架飞机延误起飞半个小时,另外到港的14个航班,因为跑道视程不到150米,只能在空中等待降落,其中一个航班在空中待了一小时。
您看,*,空气污染的危害有多大啊!它不但造成不可估量的经济损失,而且还给市民的身体健康造成极大危害,刺鼻的烟雾,使许多老人呼吸困难,有的还发生气管炎。
这起狼烟事件的原因是烧秸秆和汽车排放尾气造成的,因此,我提出以下建议:
1.把秸秆回收,做成工艺品。
2.倡议大家外出如果目的地不远的话步行或骑车去,这样既锻炼了身体又保护了环境。
3.严禁烧秸秆。
4.秸秆可以加工成肥料入土。
5.秸秆还可以加工成为一些动物的饲料。
6.多植树,让树来净化空气。
7.把秸秆绞成碎末,涂抹在广告牌上。
8.改进公交车排气气管,减少公交车的尾气排放。
9.增加公交车。
希望以上意见您能慎重考虑。
敬爱的老师,亲爱的同学们大家好:
你们每天都能看到一辆辆汽车在你的眼皮下串来串去,却曾想过这些汽车对我们的呼吸的空气造成了多大的伤害呢!
而产生这些烟的最根本的原因就是:
1.人们不进行检查车辆,结果导致发动机出故障
2.驾驶员的操作不够熟练,结果出来一大团烟雾
3.人们使用的油品质量问题
4.像黄标车(车况不佳,到年份的车辆)不及时淘汰的问题
5.车辆保养的不够到位或不进行保养,将直接影响到排出的烟雾的多少和浓度
这些问题都是导致空气指数下降的原因,看到天空中的空气一天不一天变坏,我们做为地球的一份子,我们又该怎么做呢?我们应该让驾驶员去做好5点,空气就会变好了,那5点就是:
1.每天都应该检查车辆的车况
2.加正规油品的油,不应该用不正规的油,如有买到的话,就要立刻更换
3.定期对自己的车做好相对力度的保养
我们生活在钢筋水泥的森林里,我们对生机勃勃的树木远离了。现在的交通工具、建筑物或复杂的机械都给空气带来极大的污染,它们虽然都给我们带来方便,但大家有没有想到,它们也会污染空气对人体有害的。
此时此刻某些科学家已经研制发明出许多可以净化空气的物品和机器,人们可以利用这些东西将空气中的有害物体吸走,然后将新鲜空气排出,让空气更加清新。可我们人类不能依赖这些工具,并不是有了这些工具就可以乱砍滥伐树木。因为每一棵树木都是对我们很重要的,没有大树保护土壤,泥土就会被河流冲走;没有大树美化环境,人们就生活在乌烟瘴气的地球里;没有大树维持生态环境,动物就会渐渐稀少……这样一来再多机器也没用。大家看,现在空气污染这么厉害,大家也听说过“空气污染,全球变暖”吧!如果空气污染得太厉害的话,地球就会逐渐暖和,那时南极和北极的.冰川就会融化,我们的家园会被淹没,这样整个地球都是茫茫大海,我们就会像神话一样,乘坐着“诺亚方舟”在海上漂流。所以说净化空气对我们很重要,我们要多植树让空气更清新。
让我们共同去植树,保护美好的大自然,爱护一草一木,让沙漠中的绿洲增加,大家行动起来吧!
