Pollution: a Social Problem
When we read newspapers, we often come across the word pollution. This word was not familiar to the people some decades ago. But now, it is a serious threat to us because.it means the poisoning of the air, seas, rivers and lands, which would do harm to our health. There are many factories that bring pollution to us. We can not have fresh air in the morning. This is mainly because of the poisonous smoke coming from factories, especially chemical ones. In rivers, seas and oceans, there are industrial wastes. Some factories just throw their wastes into seas or let them flow into rivers. When people drink the water from such rivers, they get poisoned. Besides, there is rubbish from ships and when sometimes an accident occurs in an ocean, oil flows out from tankers. On land, the accumulation of rubbish in the streets may dirty the city and ruin our health. This is mainly due to the improper disposal of rubbish by people. If we do mot fight against pollution, surely one day all of us will be killed. Some people like to put the blame on the industrial revolutions. On the contrary, the pollution problem will be solved only with the help of modem science and technology.

写作,能提高你的观察能力,看到什么景物、什么事情都会仔仔细细、认认真真,看出它的端倪,品出它的韵味。看看以下家乡的大气污染英语作文吧!
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. 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.
Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities. 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. 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.
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.

大海孕育了我们的生命,每一个地球人都应为保护海洋环境贡献自己的力量。下面一起随读文网小编欣赏一下海洋污染范文吧!
以前,我们的海洋是那样的美丽,波光粼粼,令人心旷神怡,流连忘返。但现在呢!这些海洋已遭受严重污染,无论是亚龙湾,还是浏阳河,都可以看到成堆的垃圾,散发出难闻的味道。
那这又是因为什么造成的呢?这都只能怪我们自己。它们主要是从油船与油井出来的原油,农田用的杀虫剂和化肥。工厂排出的污水,矿产流出的酸性溶液,它们使得大部分的海洋,湖泊受到污染,结果不但生物不能生长,就是鸟类和人类也可能因吃了这些生物而中毒死亡。这是一个难以置信但千真万确的数字,每24小时便有2.5万人(包括儿童)死亡于吃了被污染的海水里的鱼虾。还不仅仅这样,中国工程院院长,湖泊环境研究主席,科学家刘鸿量教授对全国
5500千米河段进行研究调查,报告显示,百分之二十三点三的河水段水质污染严重而不能用于灌溉,百分之四十五的河段里鱼虾绝迹,百分之八十五的河段不符合人类饮水用水标准量,而且河流自洁等生态功能也严重衰退,形势异常严峻。当我们的宇航员飞上太空,目睹我们的地球,映入眼帘的是一个晶莹的球体,上面蓝色和白色的纹痕相互交错。但是如果我们再这样让海水受到污染,那么蓝色会渐渐消失,地球将变得一片白!
为了我们有一个美好明天,为了我们的子孙后代能够更好的生活,让我们共同努力吧!

我们的环境污染我们的环境污染我们现在的生活比以前好得多,但环境跟以前简直就不能比。下面一起随读文网小编欣赏一下环境污染范文吧!
在21世纪的今天,人类的科学经济发展已经达到了很高的水平。然而我想问:你们有没有意识到人类的活动对环境会造成怎样的影响呢?
森林的乱砍滥伐不就是一个严峻的问题吗?据调查全世界森林面积正以每年上千万公顷的速度在消失。造成大量的水土流失,使许多地区成为沙漠。人类的活动范围在不断减少,这不可怕吗?
人类除了破坏森林之外,难道就没有什么破坏环境的问题了吗?不是这样的。现在我们应该看到水污染的严重性,目前世界上60%的地区面临供水不足,已有20%的人口难以得到清洁水,51%的人无法得到卫生用水。这是什么造成的呢?是我们人类自己造成的,现在的工厂及我们生活中的污水,没有通过处理就排出去。这不是最好的证明吗?据研究,每排放1立方米污水,就污染14立方米天然水。想一想,这是多么可怕的数字?
在工厂排出的浓烟里,我们不知道浓烟是污染大气的吗?科学家发现,至少有100种大气污染物对环境产生极大危害,直接影响人们的健康。
难道我们想在这种环境中生活吗?当然不想;那让我们用行动来证明吧!我们可以从我做起,从现在做起,从身边做起。树立爱自然、爱护环境的意识吧!来做宣传环保的使者!让我们一起为保护环境行动起来吧

随着各地区的经济迅猛发展,环境污染问题也越来越严重,保护环境,维持生态平衡也成为了我们每个公民应尽的责任和义务,也是为了社会更好发展的一项重要举措!下面一起随读文网小编欣赏一下环境污染的范文吧!
我们的环境污染我们的环境污染我们现在的生活比以前好得多,但环境跟以前简直就不能比。以前的空气清香并掺和着花草的芳香,河水清澈见底.........而现在呢?汽车排出的废气和工业废气相当多,河水臭气直出.........我们大家为了过上好生活,都买汽车,但车主们有没有想过这样的量使用汽车的后果。有些地方之间的距离非常近,但车主们不想跑,就直接开汽车。假如一辆汽车一天排放一千克废气,那么中国每天大约有几千万辆汽车在行驶,那么一天就要排放几千万千克的废气。
这个数目仅显示一天一千克的废气排放量和仅计算中国的废气排放情况。工厂的污染更严重,水和空气都要被污染。大量的废水排入大海和河流之中,以致大量的鱼虾、水中植物死亡和大量的水资源被污染.........我们地球上的资源也在一天一天的减少。大量可回收的品中只有3﹪是被回收并再生的。许多白色垃圾造成了白色污染。我心中的家园是和以前差不多的,可是这是很难挽回的。为了我么大家共同生活了几千万年的蓝色星球?——地球的美好未来而努力吧!

Some people, especially teenagers, are easily fall for Smartphone for these reasons. First of all, nowadays, people are under great pressure, while cell phone provides a platform for people to relax themselves.

Lack of good self-control, they are fragile to the smart phone addiction, while they supposed to focus on their study and work.
一些人,特别是青少年,极容易被智能手机吸引。原因有这些:首先,当今社会人们压力很大,智能手机提供了一个给人们放松的平台。通过玩小游戏,与朋友语音聊天,看电影听音乐,人们很容易暂时忘记他们的烦恼。其二,手机上总有新鲜事。有趣的、神秘的、种类繁多的信息吸引着大家打开手机,去了解周围到底发生了什么。当人们花了太多的时间在手机上时,就没有足够的机会去与朋友父母聊天沟通。他们的注意力已被虚拟世界所吸引。缺乏好的自控能力,他们在手机成瘾面前弱不禁风。他们理应集中精力在学习和工作上的。
I think people should take smart phone addiction seriously. Quitting addiction needs time and patience. People should turn off their phones, go outside and communicate with others face to face. Do more exercise and form optimistic attitude towards life!
我认为人们应重视把智能手机成瘾症。戒掉它需要时间和耐心。人们应该关掉手机,走出家门与他人面对面的沟通交流。多做运动,培养乐观积极的心态!

空气污染,又称为大气污染。大家写过空气污染为主题的英语作文吗?以下是小编为大家整理推荐关于描写空气污染的话题英语作文,希望对大家有所帮助。
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 arestill 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.

Dear Sir,
Hello!
My name is Nick. I’m in Grade 9. Today, I really want to join this activity, because I really want to do something to help people.
I joined a volunteer activity when I was young. I really enjoyed it. For example, I did many good things for old people, such as cleaning up the yards, washing the vegetables and so on. They are all things that I can do them well. So I have realized showing your warm heart to the old is very important. Of course, donating your kindness is helpful a lot.
In my opinion, making them happy is one of the best ways to help them. So if I have this chance, I can clean up their rooms, cheer them up and sing songs or tell stories for them. As we all know, on the one hand, we can help the old people to live better. On the other hand, helping others is helping ourselves.
If I can join this activity, I believe I can do better than before. Please write TO me soon.
Yours,
Nick

由于人类活动或自然过程,向大气中排进了一些有害物质(称污染物),当排入量够多(污染物浓度达一定限度),则使原来洁净空气的品质下降,若这种情况维持时间 够长,便会对人类、动物、植物和大气中的物品产生危害和不良影响,这种大气状态 称为空气污染。组成空气污染有三个要素:污染源、污染物浓度、对人和生物有危害。
洁净大气是人类赖于生存的必要条件之一,一个人在五个星期内不吃饭或5天内不 喝水,尚能维持生命,但超过5分钟不呼吸空气,便会死亡,人体每天要吸10—12立方 米的空气。由此可见,消除空气污染或保持污染浓度低于某个限度之下,是何等重要。
大气有一定的自净能力,现代大工业发展以前,因自然过程等排进大气的污染物, 与由大气自净过程而从大气移除的量基本平衡。但是20世纪五、六十年代以后,现代 大工业迅速发展,人类排进大气的污染物量大大超过了大气的自净能力,致使目前全 球大气都遭到不同程度的污染。这引起了各国的关注,我国已把保护环境(大气环境、 水环境等)作为国家的基本国策。

所谓“大气污染”是指有害物质进入大气,对人类和生物造成危害的现象。如果对它不加以控制和防治,将严重的破坏生态系统和人类生存条件。本文是读文网小编为大家整理的关于空气污染的作文精选,欢迎阅读。
今天,我和几个同学一起去社区采访老人,目的是想了解一下他们眼里杭州的空气质量。
我们找到的第一位访问者是一位和蔼可亲的老奶 奶,于是我们赶紧走上前说:“老奶奶,您好!我们是天长小学三(5)班的学生,我能问您几个问题吗?”老奶奶面带微笑地说:“当然可以!”我马上高兴地 问:“您觉得杭州的空气质量是现在好,还是以前好呢?”“当然是现在好!”老奶奶兴奋地回答。“为什么呢?”我紧接着又问。“现在政府重视绿化,你看 看!”老奶奶边说边往旁边绿化带指了一下,“而且呀,现在的工厂都迁到郊区去了,自然污染气体就少了。”我鞠了个躬,说“谢谢!”
后来我们又陆续采访了几位大人,他们都对现在的环境比较满意,可也有两位老人说以前的空气好,理由是以前的池水清。
我想:空气质量不管是现在好,还是以前好,对于我们来说,只有从身边的小事做起,保护好一草一木,才能让我们杭州的空气质量越来越好!

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。本文是读文网小编为大家整理的空气环境污染小学生作文,欢迎阅读。
所谓“大气污染”是指有害物质进入大气,对人类和生物造成危害的现象。如果对它不加以控制和防治,将严重的破坏生态系统和人类生存条件。
大气污染有的是由于森林火灾、火山爆发等自然因素造成的;有的则是由汽车尾气、工业废气、烟尘、爆炸等人为因素造成的,其中人为因素对大气的污染是主要的,尤其是现代交通运输和工业生产对城市大气造成的污染更为严重。因此人们对大气污染问题越来越关切。
造成大气污染的物质有:一氧化炭CO、二氧化硫SO2、一氧化氮NO、臭氧O3以及烟尘、盐粒、花粉、细菌、苞子等。
距地面几十米的近地面层大气,是人类和生物的生存空间。这一层空气质量的好坏直接影响着人类的生产和生活。近年来,由于交通运输业的发展,排放出的大量汽车尾气与空气中的一些物质成分发生化学反应,生成对人体十分有害的一氧化氮、臭氧 、乙醛等新物质。
悬浮在大气中的各种气溶胶粒子,按其大小可分为降尘和飘尘。其中降尘的粒子较大,直径大于10微米,它的自然沉降率较快。它与人类支气管炎的死亡率和农业减产有很大关系;飘尘粒子较小,直径一般在0·1—1·0微米。其自然沉降率很小,故悬浮在大气中的生命史较长。随着粒子的减小有毒元素的浓度将增加。通常小于0·3微米的飘尘能直接吸入肺泡,如长期积累,会损害呼吸机能,引起哮喘、 肺气肿、 矽肺和肺癌等不治之症。由于飘尘的污染期长和毒性强,因此它的危害性大。当大气中气溶胶粒子增加到一定程度以后,就会出现烟雾弥漫,能见度降低,太阳辐射减弱等现象。
近地面层大气污染程度与气象条件密切相关,存在着明显的季节变化和日变化。一般冬季的早晨和傍晚在无风的天气条件下空气污染最为严重。夏季由于空气层结不稳定,污染物易向高空扩散,因此一般污染不会太严重。

Water is very important for living things. Without water there can be no life on earth.
As we can see, the world population is growing rapidly day by day. So enough fresh water is needed to feed such a big population. What's more, with the development of industry, factories and vehicles produce poisonous gases or wastes, which consequently results in the pollution of water. Though fresh, a good amount of it can no longer be used. Only quite limited fresh water resource is available to human beings. So it's high time for us human beings to take quick action to protect water resource. Stop pollution and save water, otherwise, we cannot survive on the earth.
With fresh water, the world will be prosperous.
