我努力嗅着四周弥漫着的绿色的泥土芳香，真没想到在城市的喧嚣与浮躁下竟有这么一处路边公园。周围都是绿的在公园正中有一个大水塘，水塘里的水碧绿的，清澈见底，使人总怀疑水底藏着翡翠，不然叫它哪儿去吸收那么多纯净的碧绿?一眼望下去能看到水中一簇随着水波飘荡着的绿色水草。咦?在水草中怎么会有点点橘红?原来是金鱼藏在水草中休息呢!瞧，那边还有几只在自由嬉戏，有的还正吃着水上飘浮着的点点浮萍。水塘面上绽放着几朵红色的荷花，在硕大的荷花的衬托下，它们显得更加妩媚，荷花娇嫩的花瓣上还留着透明的水珠，我的心为之一颤，深深地被这生命的娇艳陶醉了。

水塘周围都是绿草和绿树，有柳树，桦树，榕树，松树等，还有很多不知名的树。它们的枝干，叶子纵横交错，形成了一个绿色的凉棚，阳光透过绿叶照到草地上都变成了绿色。枝叶中跳跃着，闪烁着迷离的光点，像一个个绿色的小精灵。一天的劳累之后，人们在“凉棚”下的石椅上休息，该是多么的惬意啊。

走过石桥，来到了水塘旁边的草地上，草翠绿翠绿的像一块绿色的绒毯，草丛中点缀着朵朵野花。这是小朋友们的天堂。他们可以在这里荡秋千，滑滑梯。野花丛中有一朵粉色的花兀自静静地开放着，它那随着清风微微摇的婀娜的身影，透出了生命的活力与柔美。一个穿着一袭绿色连衣裙的小女孩跑了过来，小手正伸向那朵可爱的花儿，或许听到旁边稍大姑娘的“别摘”的阻止声，或许她头上的蝴蝶结与那花儿一样的柔美，或许，小女孩缩回了手，笑呵呵地蹦跑到玩伴中间，那绿裙一颤一颤地融在了翠绿的草丛中，一串串银铃般的笑声荡漾在充溢草香花香的空气里，在这绿和花的世界里，在小朋友们的笑声和丛林中的鸟啼声交织的乐曲里，在我的身心得到了极大的放松，课业负担的烦躁似乎都消失在这绿色的世界里。

啊，绿色多好，如果世界永远都像这样绿，那该有多好呀!朋友们，让我们好好地爱护环境，永远生活在绿色世界之中。

导语：随着人们生活水平的提高，私家车数量不断增加。下面是yuwenmi小编为大家整理的优秀英语作文，欢迎阅读与借鉴，谢谢!

Private cars have become an important aspect of people‘s life in many parts of our country, especially in large cities such as Beijing, Shanghai and Guangzhou. While they bring much convenience to people, they are also widely criticized. There are some arguments for owning private cars. In the first place, cars allow people to move around freely, which greatly improves our living standard. We can easily drive cars for sightseeing on weekends. In the second place, cars are a comfortable way to travel, especially in bad weather. Last but not least, the car industry can boost economy by creating many job opportunities in production of steel, rubber, glass and so on. However, there are also many good arguments against cars. First of all, they pollute the environment by emitting harmful gases and giving out loud noises. In addition, cars cause a large number of traffic accidents, which bring great misery to the victims‘ families. As far as I am concerned, we should limit the number of private cars by providing better mass transportation and better service for the people. Everyone should sacrifice his or her own interest for the common good of the society.

【参考译文】

私家车已成为我国许多地区人民生活的一个重要方面，特别是在北京、上海和中国等大城市。虽然他们给人们带来很多方便，但他们也被广泛批评。有一些理由拥有私家车。首先，汽车可以让人们自由走动，这大大提高了我们的生活水平。周末我们可以很容易地开车观光。其次，汽车是一种舒适的旅行方式，尤其是在恶劣的天气里。最后但并非最不重要的是，汽车工业可以通过创造钢铁、橡胶、玻璃等的就业机会来提振经济。然而，也有许多好论据反对汽车。首先，他们通过排放有害气体和发出大声的噪音来污染环境。此外，汽车造成了大量的交通事故，给遇难者家属带来了极大的痛苦。就我而言，我们应该通过提供更好的大众运输和更好的服务来限制私家车的数量。为了社会的共同利益，每个人都应该牺牲自己的利益。

It never be explained why so many students on campus cheat in their examinations nowadays, regardless of the danger that teachers find their secret, as it did in the case of the boy student in the cartoon/photo above. What is conveyed in the drawing is most thought-provoking and should arouse our social concern.

The implied meaning of the picture is worth discussing. Firstly, the youngs always become quite illogical when they try to descide what can be done and what can not be done. In the light of this statement, some students are often willing to sacrifice their credibility for the privillage of getting more points and being regarded as outstanding students. Furthermore, some one is afired that he can‘t pass the final exams leading to his degree, in the fruit of being absorbed into computer games or disappointment in love.

Consequently, only by cheating can they graduate and get the degree on time. Although many reasons share the problem of this drawing, one of them can be singled out for recognition: the conditions of our sociaty. Such is human nature, that we can‘t avoid being influenced by environment. In short, the root of cheating in examinations and credibilililess on campus is combinition of many factors.

There is no blinding at the fact that, in dealing with a challenge on such scale, some strong, effective and necessary counter-measures should be put on our agenda. To the begin with, a widespread education campaign should be launched to make students realize the importance of credibility. What‘s more, the government departments at different levels and related orgnizations should make joint efforts and coordination of programs to creat a more credit environment for us. Only by this package deal, can build up a harmonious and healthy sociaty.

Last Sunday my father and I went fishing along a river. We found the water so dirty that we could hardly catch fish in it.

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. As we all know， environmental pollution does great harm to living things and human beings. 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.

What are the purposes of places such as museums and how should they be funded?

Nowhere in the world has the issue of museums progress been so much debated as in our society. Nowadays, more and more museums have to face the serious economic problem. Therefore, many people doubt museums existent signification. In this essay we will discuss the existent signification of museum and the solutions, such as buying by government and supporting by society

Firstly, museum is considered the historical symbol that it exhibits traditional culture of a nation. Nations of difference have different culture and history. The museum is the best way to let the younger generation savvy their ancestors history and let visitors and foreigners know varied culture and tradition.

Secondly, museum could save plenty of cultural relics that they are not destroyed and lost. The equipments of museum could perfectly save all kinds of displays.

As a result of the future of museum, the outlook is somewhat grim. People already realize this problem exists and are trying to solve it.

For one solution, the government ought to buy all museums. If museum belong to government, it will means main economic problem of museum is solved.

The second solution is that society ought to donate lots of money to maintain development of museum. The museum protects our history and culture, so we have obligation to support progress of museum.

The important thing is to protect current museums before its too late. Otherwise we will lose them.

[中考英语关于博物馆的发展问题作文

The pictures symbolically illustrate pollution is becoming increasingly serious around the globe. In the first cartoon， a man is scorching the earth on a chimney. In the second one， a famous ancient Chinese poet， Wang Bo is astonished by the heavy smoke poured by chimneys into the air and dirty river polluted by a factory. We are informed that “the autumn river is the same color with the sky”。

The drawer is sending a message about the significance of the need for everyone to fight against the danger of environmental pollution. There is no denying that the industry is indications of civilization， proGREss and development. Unfortunately， as industry develops， so will the number of factories， and the amount of industry pollutants. We are so development-oriented that we almost can sacrifice our blue sky and pure water in order to obtain a little material gain.

As a consequence， it is imperative for us to take drastic actions. On the one hand， the factories should be equipped with devices which can dispose of waste gas and water so as to prevent them from polluting our planet. On the other hand， there should be an increasingly loud voice from the public for firm actions against poisonous gas sent off and unhealthy water polluted by factories.

As we all known,food safety problems are more and more popular in our country,because

more cases about food safety problem have appeared.

Firstly,As the old saying goes,the food is what matters to the people.Food plays an important role in peoples life.So food safety influences peoples health and life.Secondly,some producers only think about earning money without thinking about ensuring food safty.they produce unqualified food.Thirdly,some food supervisory departpents dont perform their duty completely.This behavior make some producer ignore the safety of production.

If we want to solve problems that is illustrated former,we must call on the supervisory department to manage the food market.And the producers must paly their roles.Lastly,we hope that there is law that punish illegal acts.

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.

Population expansion is one of the most serious problems in the world. With better hygienic conditions and better medical care, fewer babies die today. But the birth rate remains unchanged. Moreover, the death rate has been lowered considerably by various kinds of progress. People generally live longer than they used to. All these contribute to a series of problem: shortage of national resources and food supply crowded cities and high rate of unemployment.

To solve all these problems, we must take measures to control birth rate. The first important step is to educate people-to help them understand the advantages of small families. Another important measure is to raise peoples living standards. When people full understand the consequences of population expansion, and when their standard of living is raised, the birth rate will decline without compulsion.

Though it is a difficult task, we should try in a thousand and one ways to carry out birth control If we fail to do so, the world will be too crowded to live in, and the natural resources will be used up. Then we will no longer survive on earth.

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.

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。

[关于环境污染的英语小作文

The two charts show that the increase in the U.S. population has been accompanied by a corresponding decline in the number of wildlife species. Far too many species have been lost already. This poses a danger to ecological balance.

As the human population expands, more and more wild animals are hunted for food, or because they are thought to present a threat to man. But studies show that one of the primary causes of the disappearance of wildlife is pollution, which is one of the consequences of population growth and economic development. This makes us wonder if man is able to share this planet in harmony with other life forms.

In my opinion, it is imperative to take steps to reverse the disturbing trend illustrated in the charts. One measure would be to forbid the building of cities in areas where wild life is threatened with extinction. But, more imporantly, man must learn to stop polluting the environment, or he himself will become extinct.

depending on personal experience, personality type and emotional concern, we find that some people hold the idea of living in the country, while others prefer living in the city. in my opinion, i prefer the city life, though it has advantages and disadvantages.

first of all, city life is very colorful. city is the center of the surrounding area. so, it is also the most booming place having the best things. there are many great things and wonderful activities in the city, while there isn’t in the country. for example, there are kfc, wonderful shopping mall, delicious food from various places, dancing club, different kinds of activities and so on. we can also learn the culture from all the countries. despite city life is so wonderful, it still has many disadvantages. nowadays, with the improvement of people’s living standard, people have more cars and more people come to city, and then the city becomes more and more crowd. as a result, traffic jam emerges, which makes great inconvenience for people to go out. what’s worse, the air pollution becomes serious day by day, which is bad for people’s health.

to sum up, every coin has two sides. living in the city also has good side and bad aspect. whether like living in city or not depends on individual thinking. as myself, i like living in city though i know the disadvantage of living in city.

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.
