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.

空气污染是当今世界的主要问题之一。在现代化工业国家中，办工厂需要大量的能量。

汽车、火车、飞机和公共汽车需要能量，太。几乎所有这些能量都是由燃烧的燃料产生的。燃烧产生的废物，其中一些留在空气中，造成空气污染。

科学家们正在寻找办法来阻止空气污染，尤其是在大工业区和人口稠密的城市。

他们正在研究新的发电方式，这种方法对环境的破坏性更小。与此同时，许多发电厂正在现代化，以减少污染的物质。

同样，工程师们也正在努力设计新的发电厂，确定新的建厂地点，把对环境的危害减少到最低限度。然而，在我们拥有一个“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防止和控制空气污染。

环境保护主义者的任务似乎没有尽头。人们会不断找到控制污染的新方法。

cars have created a lot of serious problems in our world. all the time, they are pumping huge amounts of waste gases into the atmosphere, causing disease and even death.

one possible solution is to design and develop clean cars and clean fuels. but it may take decades for the new models to completely replace the traditional ones.

another solution is to develop modern public transportation systems and restrict the use of private cars. if the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not drive private cars. on the whole, the elimination of air pollution needs the co-efforts from the government and the public. this problem will be solved only with the help of science and technology.

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.

污染变得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通过屏蔽自己的脸。工厂的有毒气体罚下,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,人们显示出真正的担忧的问题。例如,有一个公共的越来越大声对汽车污染公司行动。

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,我们应该制定具体的解决问题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。

Today, as the economy develops fast, people can buy what they need, the

producers provide them all the new things, so the factory produce many products,

in order to make the biggest profit, they don’t deal with the pollution. Water

gets polluted, it does harm to people’s health, we drink water everyday, the

government controls the producers to figure out some ways to deal with the water

pollution.

Where is my home?

Some fish are forced to leave polluted water and are flying in the sky. But unfortunately, air is also so polluted that they have to wear masks. Each of them is crying, “Where is my home?” What a terrible sight!

Mankind has brought so much pollution. Waste is being poured into rivers and seas. Poisons to kill pests in farming and chemicals go into rivers and seas, too. Poisonous gasses from factories also make the air so dirty. The whole balance of nature is being destroyed as a result of our ignorance of the environmental protection.

Personally, man can not live alone on the earth. Should fish die from serious pollution, so would man! It is high time we did something to prevent such a scene from happening.

【译文】

何处是我家?

一些鱼类被迫离开受污染的水，并在天上飞。但不幸的是，空气污染，也使他们不得不戴上口罩。他们每个人都在哭，“我的家在哪里?”这太可怕了!

人类带来了如此多的污染。废物被排入河流和海洋。毒药杀死农业害虫和化学品进入河流和海洋去，太。从工厂有毒气体也使空气这么脏。整个自然界的平衡被毁坏了我们对环保的无知造成的。

就个人而言，人不能独自生活在地球上。如果鱼死了严重的污染，将男人!现在是时候我们做了一些，以防止发生这样的场面。

each year there is an increasing number of cars on the roads as millions of new cars are produced. one out of six americans works at making cars, driving trucks, building roads or filling up gas. americans couldnt live without cars!

most americans would find it hard to imagine life without a car. however, some have realized the serious problem of air pollution caused by cars. the polluted air becomes poisonous and dangerous to health.

one way to get rid of the polluted air is to make a car without pollution. but to build a clean car is easier said than done. progress in this field is slow.

another way is to replace car engines with something else. inventors are now working on steam cars as well as electric cars. many makers believe that it will take years to develop a practical model for us.

to prevent the world from being polluted by cars, we have to make some changes in our lives. americans, for example, have to cut down on the number of their total cars.they are encouraged to use bicycles, which are thought to help keep the air clean.

Health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out.

We all know that clean air is important to good health. Wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air.

If there are impurities in the air, they may be absorbed by our bodies and make us ill.

We need clean air, but unfortunately, air pollution is globally present, especially in cities.

Many large cities are anything but pollution-free. Our cities have many factories, which we need to make food, clothing and other things.

Every year these factories pour millions upon millions of tons of smog into air.

Power plants and houses that burn coal add greatly to air pollution. Besides, there are more cars in cities now.

Once out on the streets, they will take in fresh air and replace it with poisonous gases.

Our country is trying hard to prevent and control air pollution. As long as every citizen also realizes its importance and makes join efforts, the day will come soon when people will take in only clean air.

Then, the sunlight will no longer be blackened out by smoke and soot.

我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。以下是小编给大家整理的形势与政策论文：城市水环境的问题探讨的内容，欢迎大家查看。

摘要: 随着经济快速发展，城市生态形势压力也与日俱增，水环境问题已成为制约社会发展的大问题，环保基础设施建设严重落后，城市生活污染物未得到有效控制，工业污染源未得到严格治理，农业污染日益突出，部分河段水质受污染严重，河水发黑发臭，完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词：城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分，城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响，我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失，造成了城市生态环境、水环境的进一步恶化。针对这样的情况，我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发，恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型，由于城市人员密集、工业化生产程度高，所以，城市用水需要较高的质量、较大的供水量、稳定的供给，这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高，所以，单纯依靠城市区域的供给和开采往往难于满足城市发展的需要，因此，大众城市往往需要从城区周边或外地调水来满足城市的用水需要，“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方，城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中，在日积月累的大量污染的影响下，城市水环境受到了严重破坏，并且这一现象有蔓延和恶化的趋势，造成水环境的脆弱和生态的破坏，影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个，一是，城市生产和生活中大量污染源渗入地下，造成对地下水资源和水环境的破坏;二是，城市地表硬化导致城市地面下渗量的减少，在大量开采地下水的同时，没有必要的补充，出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本，科学发展

把维护广大人民群众的根本利益作为第一点，把群众最关心、最直接和现实的水环境保护问题为重点，转变发展观念，重视生态文明建设，加快建设资源节约和环境友好社会，走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品，水环境治理应突出重点，优先保护饮用水源，确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩，把COD削减量考核指标纳入到区县水环境治理目标体系中，明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标，即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金，对节能减排效果明显，有一定经济基础，技术条件成熟，符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集，污染来源复杂。为此，河道治理将坚持“先截污、后清淤、先治理、后换水”的原则，周密排查河道沿线污染来源，大力实施清淤、截污、生态护坡、河岸绿化等措施，加强河道水体自净和生态修复功能;在突出截污治理的同时，各区县还将坚持污水处理厂、配套管网同步建设，大力提升现有污水处理厂运行负荷率，妥善解决污水出路，切实提高河道水环境质量。

5、加强协作，落实责任

市水务局于去年成立了河道水环境考核办公室，将清水工程已治理河道纳入考核范围，各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制，有效巩固水环境治理成果。此外，目前市政府已正式批准本市河道水环境实施“河长制”管理意见，即将公布全市主要河道“河长”名单，构建完善的河道水环境管理长效机制，为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述，我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。

In recent years,we can clearlyfeelthe environment around usis more and moreobviouspollution,environmentalsafety problems have beenvery serious.Because of ourpreviouspolicy isheavy economic development,light environmental protection,resulting inenvironmental pollution,ecological damage is very serious,mainly manifested in the following aspects:

近几年来，我们可以明显的感觉到我们身边的环境污染愈显明显，环境安全问题已十分严重。因为我国以往的政策方针是重经济发展，轻环境保护，所以造成环境污染、生态破坏十分严重，主要表现为以下几个方面：

In the atmosphereof security,since the middle of the twentieth Century,industry andthe rapid development of transportation,causingairpollution is increasing.Air pollutionisharmful to human health,but alsoaffectthe growth of plants and animals,destruction ofbuilding materials,serious when canalter the earths climate.According to the survey,China each yearfrom air pollutionand economiclosses amounted to about 100000000000 yuan.

在大气安全方面，20世纪中叶以来，工业和交通运输迅速发展，造成了大气污染的日益加重。大气污染既危害人体健康，又影响动植物的生长，破坏建筑材料，严重时会改变地球的气候。据调查显示，我国每年因大气污染造成的经济损失高达1000多亿元。

In the water security,waterpollution in Chinais very serious,widespread around thedrinking watersafety problems,a direct threat tohuman and animalsurvival.In recent years,although theinvestmentfund managementa lot ofHuaiheand other waters,but the effect is not obvious,the overall situationis still deteriorating.

在水安全方面，我国水污染问题十分严重，各地普遍存在着饮用水安全问题，直接威胁到人畜生存。近几年虽然投入大量的资金治理淮河等水域，但效果并不明显，整体情况仍在恶化。

In a biologicalsafety,the invasion of alien speciesmass,a serious threat to thebiological diversity of china.In fact,the blind introduction of foreign species,damage the environmentbalance,serious and evenlead to disastrous consequences.At the same time,because ofthe destruction of the ecological environmentandwildlifehunting,biologicalextinctionrateis rapidly increasing.

在生物安全方面，大规模的外来物种入侵，严重威胁了我国的生物多样性。事实证明，盲目引进外来物种，会破坏环境平衡，严重时甚至带来灾难性的后果。同时，由于生态环境的破坏和对野生动植物的滥捕滥猎，生物消亡的速度正在迅速增加。

In the security of land,theland desertification and soil erosionis very serious.In addition,the cultivated landquality in Chinadecreased very rapidly,at the same time,because of the seriousland pollutionphenomenoncaused byexcessive use ofpesticides,is directly related tofood safety problemof residents in our country.China is adeveloping country,in the face ofenvironmental pollutionpressure not only fromChinaitself,andappliedpressurefromsome developed countries abroad.Therefore the development ofeconomy andenvironmentis a need for us toissuelongface,and it alsoneed to rely on theparticipationof each and every one of us.

在土地安全方面，我国土地荒漠化和水土流失的情况已十分严重。另外，我国耕地质量下降非常迅速，同时由于过度使用农药等造成的严重的耕地污染现象，直接关系到我国居民的食品安全问题。我国是一个发展中大国，面对环境污染方面的压力不仅来自国内本身，还有来自国外一些发达国家施加的压力。因此发展经济和治理环境是一个需要我们长久面对的问题，而这也需要靠我们每个人的共同参与。

our lives. Americans, for example, have to cut down on the number of their total cars.They are encouraged to use bicycles, which are thought to help keep the air clean.

But this change does not come easily. A large number of workers may find themselves without jobs if a car factory cioses down. Thus the problem of air pollution would become less important than that of unemployment. Although cars have led us to a better life, they have also brought us new problems.

每年有越来越多的汽车在新车的人数以百万计的生产道路。出六个一工程美国人制造汽车，驾驶卡车，修建道路或填补气体。美国人不能没有车！

大多数美国人将很难想象没有汽车的生活。然而，一些已经认识到空气污染严重的问题，汽车造成的。污浊的空气变成有毒的和危险的健康。

一个办法让污浊的空气，就是自己做，无污染的汽车。但要建设一个清洁汽车谈何容易。在这一领域的进展非常缓慢。

另一种方法是别的东西取代汽车发动机。发明者现正蒸汽汽车以及电动汽车。许多厂商认为，这将需要几年发展为我们实践模式。

为了防止世界被污染的汽车，我们要在我们的生活有所改变。例如，美国，不得不削减对它们的总人数下降cars.They鼓励使用自行车，这被认为有助于保持空气清洁。

但是，这一变化来之不易。阿大批工人可能会发现自己没有工作，如果汽车厂cioses了。因此，空气污染问题将变得并不重要，重要的失业问题。虽然汽车已使我们更好的生活，他们也给我们带来了新的问题。

[英语作文：汽车污染环境

More than half of Beijings adult single children dont intend to have two kids, even though national policy allows them to do so.

The countrys family planning policy of the late 1970s restricted urban families from having more than one child to control population growth.

However, a new survey by the Beijing Administrative Institute shows 52 percent of those now-grown-up single children, who are allowed two offspring, do not want a second child.

Many cited economic pressures as a factor.

The results were released on Sunday at the Beijing Forum, organized by Peking University.

Beijing has roughly 2 million only-child adults.

More than 1,100 people from only-child families, aging 20 to 34, were polled.

Only 24 percent of respondents said they would like to have two children.

More than a quarter of respondents would opt for a "DINK" (double income, no kids) lifestyle.

Survey figures showed that respondents with a primary education wanted 1.1 children on average, those with a bachelor degree wanted 1.3, and those with masters or higher degrees wanted 1.5 children.

"Beijing has maintained a super low birth rate - less than 1.3 children in a family in average - for nearly 20 years, posing increasing pressure on the countrys aging population," Hou Yafei, a professor with the institute, said.

Hou said that the top four factors that determined peoples intentions to have children were "income, child care, housing and policy conditions".

"The government should encourage couples from one-child families to have a second child and should provide better welfare services."

This would promote population sustainability, Hou said.

The survey also found that people with higher education backgrounds intend to have more children because they are more confident with their financial security.

In my hometown, the air is polluted seriously. However, in recent years,

the pollution gets from bad to worse, because of the increasing number of

private cars. Especially during the rush hours, too many private vehicles move

slowly on narrow roads, emitting a large amount of waste gas. Moreover, the

poisonous gas sent by the nearby factories is also one of the main causes of

pollution. Therefore, it’s demanded that immediate and effective measures must

be taken to restrict private cars and public transportation must be developed to

the largest extent. Besides, we should use renewable and clean energy

recourses.

In the 21st century, humans science economic development has reached a very high level. But I want to ask: do you have any aware of human activities on the environment will be what kind of impact?

The deforestation of the forest is not a serious problem? According to the survey the world forest area is in at an annual rate of millions of hectares of disappear. Caused a lot of water and soil loss, make many areas become desert. Scope of human activities in the declining, its not scary?

What human besides destroying forests, dont damage the environment problems? It is not. Now, we should see the seriousness of water pollution. At present, 60% of the country in the world face the shortage of water, 20% of the population is difficult to get clean water, 51% of the people do not have access to sanitary water. This is caused by what? Is, that we are causing ourselves now factories and sewage in our life, not by processing is out. This is not proof of that? According to research, each 1 cubic meter of sewage discharge, 14 cubic meters of natural water pollution. Think of it, this is what a terrible number?

In the discharge of smoke in the factory, we dont know the smoke is atmospheric pollution? Scientists have found that there are at least 100 species of air pollutants produced great harm to the environment, directly affect peoples health.

Do we want to live in such an environment? Certainly dont want to; Then let us use action to prove it! We can start from me, start from now, start from the side. Love nature, the consciousness of environment protection! To do propaganda environmental protection angel! Lets take action to protect the environment

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

导语：近年来我国多地雾霾天气不断增多，极大地影响了人们的健康与生活。下面是yuwenmi小编为大家整理的相关作文，欢迎阅读与借鉴，谢谢!

With the broadcast of smog,this long-standing environmental problems,become the hot discussion once again.According to some reports,the frequent appearances of smog obscure the clarity of the sky recently.Some people drove slowly on the road because they could not see clearly. They also suffered from many illnesses caused by smog.

Smog is the general expression of various higher-than-permitted suspended particulate matter (such as PM2.5) in the atmosphere,which express the state of air pollution .It contains fog and haze,both of them are disastrous weather. Fog consists of a large number of tiny water or ice crystals.Its actually a harmless natural phenomena that makes visibility worse .Haze is air pollution in which is mixed up with dust, smoke and other dry particles. The components that make up haze may have negative effect on peoples health, especially for children and the old.

So its necessary to find out the reason why leads to smog and work out the resolution.If we trace the cause for smog weather ,the main points are natural causes that include windblown dust and manmade causes which include three aspects.Firstly,china s air quality standards are rather lax and evaluation factors are limited.Secondly,some enterprises just go for economic interests instead of observing relevant law and regulations.Obsolete equipment、industrial fuel burning and manufacturing operations are high likely to emit much wasted air.Thirdly,across our society ,relevant protection awareness has not built up.Just for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for smog.

To settle this problem,a series of meaures should be taken as follows.Primarily,we should establish a sound control system of smog. Not only can environmental protection departments strengthen air monitor,but government should enact more strict laws and regulations.Moreover,Reduce pollution sources is the fundamental solution to cut air pollutants. For example,we can reduce the amount of fuel vehicles or close down high polluting enterprises.Developing green and energy-saving energy can lower the emission of smog.Last but not least, People should do personal protection.They need to reduce the time for outdoor sports and pay attention to rest in smog days.Everyone all over the country should take measures to reduce the smog weather. We can use more public transport such as the bus and the underground so that the number of cars will be limited.Also,people should plant more trees. As far as Im concerned ,if we work together to do such measures ,smog weather will vanish completely and we will get clear and blue sky.

随着烟雾的传播，这个长期存在的环境问题再次成为人们讨论的热点，据一些报道，烟雾的频繁出现模糊了最近天空的清晰度，有些人因为看不清楚而在路上缓慢行驶。他们也遭受了许多由烟雾引起的疾病。

烟雾是大气中各种高达允许悬浮颗粒物(如PM2.5)的普遍表现，它表示大气污染的状态，含有雾和霾，两者都是灾害性天气。雾由大量的细小的水或冰晶组成，实际上是一种无害的自然现象，它使能见度变得更糟。Haze是空气污染，它与灰尘、烟雾和其他干粒子混合在一起。构成雾霾的成分可能对人们的健康产生负面影响，特别是对儿童和老年人。

因此有必要找出原因，导致烟雾和工作的决议。如果我们追溯雾霾天气的成因，主要是自然原因，包括风沙和人为原因主要有以下三个方面：首先，中国的空气质量标准是相当宽松的评价因素是有限的。其次，一些企业只是去代替观察相关的法律和法规的经济利益。设备陈旧、工业燃料燃烧和生产经营高可能发出多浪费空气。然后，在我们的社会中，相关的保护意识还没有建立起来。只是为了方便出门的缘故，人们越来越依赖旅行和工作的汽车，而汽车是主要原因烟雾。

为了解决这个问题，应采取一系列措施如下。首先，我们应该建立一个健全的烟雾控制系统。环保部门不仅要加强大气监测，而且要制定更加严格的法律法规，减少污染源是减少大气污染物的根本途径。例如，我们可以减少燃料量或关闭高污染企业，发展绿色、节能的能源可以降低烟雾排放。最后但并非最不重要的，人们应该做好个人防护。他们需要减少户外运动的时间和关注在烟雾天休息。全国各地的人应该采取措施减少烟雾天气。我们可以使用更多的公共交通工具，如公共汽车和地铁，这样汽车的数量将是有限的，人们也应该种植更多的树。就我而言，如果我们共同努力，采取这样的措施，烟雾天气将完全消失，我们将得到明确和蓝天。

presently, the world is faced with serious water problems. but these problems witt become more intense and more comple in the future. our increasing population witt tremendously increase urban waters, primarily sewage. on the other hand, increasing demands for water witt decrease substantially the amount of water available for diluting wastes.

rapidly epanding industries which involve more and more comple chemical processes will produce large volumes of liquid wastes. many of thesewitt contain chemicals that are poisonous. to feed our rapidly epanding population, agriculture will have to be intensified.

this will involve ever increasing quantities of agriculture chemicals. from this, it is apparent that drastic steps must be taken immediately to develop corrective measures for the pollution problems.

there are two ways by which these pollution problems can be lessened. the first relates to the treatment of wastes to decrease their pollution hazard. this involves the processing of solid wastes "prior to" disposal and the treatment of liquid wastes to permit the reuse to the water or best reduce pollution upon final disposal.

the second approach is to develop an economic use for all or part of the wastes. farm manure is spread in fields as a nutrient. wastes from sewage disposal plants are used in some areas both for irrigation and for the nutrients contained.

liquid wastes from other processing plants may also be used as a supplemental source of water. only by doing these promptly now can we epect to solve the serious water problems in the future.

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.

据报道,在中国十个大城市被排名前二十的城市污染指数最高的国家。这意味着是时候我们做了一件控制局势。许多因素导致恶化的形势:工业废物注入空气,湖泊和河流,越来越多的汽车涌入街头,塑料袋的广泛使用等。

就我看来,更严格的法律法规必须实现检查污染。释放废弃物未经许可的行业应该是严重的罚款。汽车应该配备最小化他们释放的废气到空气中。和使用塑料袋和一次性餐箱应被禁止。更重要的是,媒体应该发挥重要作用在植入的环境意识到人们的心灵。如果每个人都朝着一个共同的目标工作的环境更好,我们可以创造一个更清洁和更可爱的世界,为我们和未来的一代。

In order to build a civilized city, we students should try our best to behave well in the activities.

It’s a good habit to keep our clothes clean and tidy. Our city should be kept clean every day. Don’t throw litter or spit about. It’s good manners to say “Thank you” and “Please”, and so on. We should never say dirty words. Be friendly to others and always ready to help the people in need. For example, when we are on a bus, we should give our seats to the old and the women with babies. We should also obey traffic rules. When the traffic lights are red, we should stop. And we’d better not talk or laugh loudly in public.

If everyone behaves well , our city will be more beautiful and more attractive.

为了建设文明城市，我们学生应该尽力在活动中表现良好。

保持衣服干净整齐是一个好习惯。我们的城市应该每天保持清洁。不要乱扔垃圾或随地吐痰。说“谢谢”和“请”是礼貌的，等等。我们不应该说脏话。对别人友好，随时准备帮助需要帮助的人。例如，当我们在公共汽车上时，我们应该给老人和有婴儿的妇女让座。我们也应该遵守交通规则。当交通灯是红色的时候，我们应该停下来。我们最好不要在公共场合大声说话或大笑。

如果每个人都表现良好，我们的城市将会更美丽更迷人。

Create a Green Campus

It is of great importance to make and maintain a green campus in our university or college. Obviously， a growing number of people are beginning to realize that it is our duty to do that in the present days， since the concept of “a green world” has become the focus of the society. The idea of “a green campus” is beyond a green environment. To begin with， the development on the campus is to be sustainable and recyclable. Some of the authorities’ budget should be on how to reduce of the waste. What’s more， we’d better be aware of the seriousness of pollution around us. Thus the idea of environmental protection may become a common occurrence in our daily life. It is necessary that effective actions should be taken to protect our campus from waste and pollution， and hence these activities are to play an increasingly important role in our day-to-day life. Certainly， there is little doubt that further consideration must be paid to our green campuses.

View of two children

now, our country the number of straight line rise, because the two population increasing, a series of problem, here, Ill give you something about with that!

The current family planning policy is unfair, urban residents having only one child, rural residents the first child is female of, can have two children. To have two children, however, leads to the housing problem, population increase, also takes more house, now scientists show that Chinas housing life for 30 years, while western countries housing service life is 2 times of our country, therefore, our countrys house of fast, down too fast, the house is always not enough, so a few people who are facing problems dont have a house to live.

Today, our countrys arable land has also been a lot of problems, such as: 1, due to the large area reclamation woodland lawn, cultivated land is widening. 2, due to the large-scale afforestation, reduce cultivated land quickly. 3, due to water loss and soil erosion, land desertification, human development blindly, arable land decrease quickly. 4, due to the impact of foreign agricultural products, a large number of cultivated land desolate. Because of population increase, to a large number of land reclamation, to a large number of occupation of land, only in this way can we have a new technology, will have a house to live in. So, our countrys land area is greatly reduced. But, our country a lot of land is occupied, can continuously reduce the cultivated land area, arable land decrease, many kinds of food less, even some people starve to death. Two population increase, the employment problem also more and more competition, such as: 1, the our country population base is big, need more employment, employment peak last a long time. 2, needs to improve employment mechanism, talent market, labor market development has yet to be perfected, labor elements configuration has not yet reached full optimization. 3, employment concept updating, lack of initiative entrepreneurial enthusiasm, "such as" "by" the ideas of the "to" still exist, not from their own and realistic environment, employment expectations are too high. So, young people in employment in our country may not work, cant bring home the bacon. In order to themselves and others in the future, please have fewer, eugenics. Boy or girl, is the backbone of the motherland in the future.

对二胎的看法

现在，我国的人数直线上升，因为生二胎人口增多，造成的一系列问题，下面，我给大家加讲一讲吧!

现行的计生政策不公平，城市居民只能生一胎，农村居民第一孩字是女的，能生二胎。可是，生二胎会导致住房问题，人口增多，需要的房子也多，如今科学家证明我国的住房寿命达30年，而西方国家的住房寿命是我国的2倍以上，所以，我国的房子修的快，拆的也快，房子始终不够，因此少数人正面临没有房子住的问题。

如今，我国的耕地也受到了很大的问题，如：1、由于大面积垦林地草地，耕地不断扩大。2、由于大规模造林，使耕地迅速减少。3、由于水土流失，土地沙漠化，人类盲目开发，耕地面积迅速减少。4、由于外国农产品冲击，大批耕地荒芜。就是因为人口增多，才大量的开垦，才大量占用土地，就只这样我们才能有新科技，才会有房子住。所以，我国的耕地面积大大减少。可是，我国大量的土地都被占用，耕地面积就只能不断的减少，耕地减少，种的菜就少了许多，甚至有些人被饿死。生二胎人口增多，就业问题竞争的人也越来越多，如：1、我国人口基数大，需要就业人员多，就业高峰持续时间长。2、就业机制有待完善，人才市场、劳动力市场发育还有待完善，劳动力要素的配置还未达到完全优化。3、就业观念有待更新，缺乏主动择业创业的积极性，“等”“靠”“要”的思想仍然存在，不从自身和现实环境出发，就业期望值过高。所以，我国年青人在就业方面有可能没有工作，就不可以养家糊口。为了自己和他人的未来，请少生、优生。生男生女都一样，都是祖国未来的栋梁。

with the improvement of our living standard, more and more people can afford a car. as a result, our roads are more often than not crammed with cars. however, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. so nowadays we advocate to lead a low-carbon life.

my suggestion is we should ride bikes more often instead of driving cars.by riding a bike, we can not only exercise our body but also protect our environment. why not have a try, my dear friends?

与我们的生活水平的提高,越来越多的人都买得起汽车的.因此,道路往往没有堆满了汽车.然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重.所以现在我们提倡过低碳的生活.

我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境.为什么不试试,我亲爱的朋友?
