Thanks to my parents, I have been to many places. I feel so lucky to

witness the scenery by my eyes. I love to travel since I was very small. I have

made up my mind that I must continue my journey on my own. As I grow up, I have

planned some trips and learned a lot.

Travel helps me to be independent. For many people, they trend to travel by

groups, which is very convenient. The companies plan everything for them, and

they just need to follow the schedules. But as for me, I only enjoytraveling

freely, so I will scan a lot of information and select the useful message. I

learn the history and culture of the countries and get to know all kinds of

applications.

The most important thing of travel is to broaden my vision. When my friends

talk about the beautiful places from the textbook, I will tell them that I have

been there and can give them my opinion. The way I talk and the knowledge I

offer to them make me stand out and I am so proud of myself.

I study in the No.1 Primary School. Its one of the best primary schools in my city. There are four buildings in campus.Two of them are teaching buildings. The other two are library and gym. The teaching buildings are huge and the classroom is large and bright. There are plenty of books in the library. I like reading books in the library. After class, students like playing in the gym. It’s a popular place after class. Besides, our teachers are great. They care much about students. I am happy to study in my school.

我就读于我们市的第一小学，那是我们这最好的一所小学。学校共有四栋建筑，两栋是教学楼，另外两栋分别是图书馆跟体育馆。我们的教学楼非常宏伟壮观，教室也是又宽敞又明亮。图书馆里面有很多藏书，所以我非常喜欢在那读书。课间时候，同学们都喜欢在体育馆里玩，那儿可是个热闹场所。另外，我们的老师也非常好，对学生都很关心。我喜欢在这所学校读书!

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,whichgreatly improves our living standard.We easily drive cars for traveling.In second place,When we have something urgent to do,cars are quick than other vehicles in some extent.Last but not least,the car industry can boost economy by creating many job opportunities.

However,there are also many arguments against cars.First of all,they pollute the environment by emitting harmful gases.What’s more,cars cause a large number of traffic accidents,which bring great misery to their family.

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 mass society.

The campus environment is becoming more and more serious, the plastic bags are strewn all over the floor, the scraps of paper are flying, and there is a smell of smoke from time to time. As a result of this, it is conceivable that the school will be what it will be, and no one will dare to imagine it again.

Therefore, in order to make the campus more beautiful and clean, as long as we work together, we will take care of the plants and trees as they do to our lives. Dont litter the peel and plastic bags. We want to be like a cleaning worker, and when the plastic bags and the scraps of paper are thrown on the ground, whether you throw it or not, you must always pick it up. In school, it is hard to prevent spitting or snot.

The students put out their hands, let us protect the campus together, let those bad phenomena which harm the classmate bad, the harm to the classmate disappear forever! In this way, the sunshine will be brighter tomorrow, the air will be clearer and the campus will be more beautiful and tidy.

Marine lives in fish and all kinds of chemical substances,is very important for human.But many people like throwgarbage into the sea,the sea will pollution.Cause fishdeath,water depletion.We should keep our environment,to protect the beautiful sea.

海洋里生存着鱼和各种化学物质,对人类很重要.但是许多人类喜欢向海里投垃圾,海水就会污染.导致鱼儿死亡,海水枯竭.我们应该保持环境,一起保护美丽的大海.

Desert, rose water, cancer... With humans dont care for the environment, damage to the environment has a lot to do. Like a clear brook became black stink; Dense woods turned into bare land; A variety of animals also slowly become extinct. The earth mother is sick!

Fish said to the bird, "you know what? This small pools has been dead for more than a dozen fish!" , the bird said, "yeah! Dont fresh the air here, all want to put my stuffy dead!" .

Trees in the forest, said: "life now is very dangerous, or by some naughty children bend the branches up; or that has been cut off. In short is having a hard time."

Reptiles are also said: "ah! Our days sad ah, also is afraid of people eat, or in the zoo, or be in the circus show. Its really a terrible world!"

We these uncivilized habits will not only bad for plants, animals, also not be good to oneself. Some people just because of air pollution, some people get sick because of water pollution, and mother born child is abnormal, there are some men smoking lit trees, also caused the fire, forest were destroyed, ecological destruction. In this way, the earth slowly turned into a garbage dump in the universe.

The earth is our survival homeland, destroy the earths environment, is destroying our human oneself. So, we human beings should protect the environment. Protect the environment, our children to start small, put the rubbish into the dustbin, and sent him to the correct boxes. Hope everyone is less by car and more riding a bicycle, advocate green travel. Save water, reduce waste. Let the earth mothers illness get better gradually. Let the sky bluer, the water cleaner, the grass is greener and more colourful flower. Become the most beautiful and good earth!

The fish in the water is much more slowly, and thrive on the trees of the forest, the animals also have a happy home! This should be our beautiful home, changed the original bad habits, protect the environment.

沙漠、涨水、癌症……都是跟人类不爱护环境，破坏环境有很大的关系。像清澈的小河变成了乌黑发臭;茂密的树林变成了裸露的土地;一种种动物也慢慢灭绝了。地球妈妈生病了!

小鱼对小鸟说：“你知道吗?我们这个小水池已经死了十几条鱼了!”，小鸟说”对呀!这里的空气一点儿也不清新，都要把我闷死了!”。

树木们在森林里谈到：“现在的生活很危险，要不就是被一些顽皮的孩子把树枝弄弯;要不就是被人们砍伐掉。总之就是不好过。”

爬行动物们也说：“哎!我们的日子也难过呀，就怕被人们吃了，或被关进动物园里，或被放进马戏团里表演节目。这真是一个可怕的世界呀!”

我们这些不文明习惯不光会对植物、动物不好，对自己也没什么好处。有些人就是因为空气污染而死亡的，有些人因为水污染而得病，还有的妈妈生下来的孩子就是畸形的，还有一些男人吸烟把树木点燃，还引发大火，森林被烧毁、生态被破坏。就这样，地球慢慢变成了宇宙中的垃圾堆。

地球是我们生存的家园，破坏地球环境，就是破坏我们人类自己。所以，我们人类要保护环境。保护环境，我们小孩要从小事做起，把垃圾丢到垃圾箱里，还要把他送到正确的箱子里。希望每个人都少坐汽车，多骑自行车，倡导绿色出行。节约用水，减少浪费。让地球妈妈的病渐渐好起来。让天更蓝、水更清、草更绿、花更艳。变成最美好的地球!

水里的小鱼也慢慢多了，森林里的树木也旺盛起来了，动物们也有一个幸福的家园了!这应该才是我们美丽的家园，把原来的坏习惯改了，保护环境。

The earth is our common homeland, we will not be able to live without the earth, so we should protect our home, cant let those greedy people destroy the earth.

Due to the deforestation of people, from underground oil, coal, discharge of sewage, chemical plant, built the earth has been scarred, because the tree is his bones and muscles, underground oil is his blood, the coal is his insides, the earth must be very painful, very hate him sons and daughters, should treat him so, but people did a show of indifference, said: "the earth is not to provide us with resources, hearing this, I am very sympathetic to the earth, feel sad for the earth."

And better homes in my heart is like this: people living in wooden houses, the home use is very of environmental protection, the source of all is depend on the sun can, as long as the sun will have electricity, car is the solar energy, environmentally friendly, green city, the birds come here to live and work in peace and contentment, singing a happy song, people no longer deforestation, wont hurt the earth, all living a happy good life, also wont kill some innocent little animals, the earth saw it all, happy smile, his scar is finally good, again is a fresh world.

While people used to hurt the earth, but now most people realize his mistake, and the country will also from time to time to do a publicity, to remind people to protect the environment, to become a good citizen, if people correct mistakes, I think my homeland in my heart, can come true soon.

由于人们的乱砍乱伐、从地下抽油、挖煤、排放污水、建化工厂，地球已经伤痕累累，因为树木就是他的筋骨，地下油是他的血液，那煤就是他的五脏六腑呀，地球一定很痛，很恨他的儿女们，竟然这样对待他，可人们却一副无所谓的样子，说：“地球不就是给我们提供资源的吗，听了这话，我非常同情地球，为地球感到悲伤。”

而在我心中的美好家园是这样的：人们都住着木头房子，家里用的东西都是很环保的，一切都是靠太阳的源能，只要有太阳就会有电，车都是太阳能的，很环保，城市里绿树成荫，鸟儿们都来这安居乐业，唱着愉快的歌声，人们不再乱砍乱伐，不会再伤害地球，都过着幸福美好的生活，也不会再杀害一些无辜的小动物，当地球看到了这一切，高兴的笑了，他的伤痕终于好了，又是一个精神焕发的地球了。

虽然人们以前伤害了地球，但现在大部分人都认识到自己的错误了，而且全国也会时不时的做一做宣传，时刻提醒人们要保护环境，做一个好公民，如果人们都改正错误的话，我想我心中的美好家园，不久就能成真的了。

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。

Important to save water

Water is a kind of liquid. It has no taste or smell. It is transparent, too. Water is useful and is important to us. Why? For example, we use water to water the plants. We use water to wash our face or to have a bath. We drink water or we will die…Water is also very important for China. There are 2.8 hundred millions of steres of water in China, but everyone can only use 2300 steres. It is only twenty–five per sent in the world.

Not too long ago, there was a man called Jacques Cousteau. He loved the beautiful colors, and the beautiful fish in the sea. However, when he returned some years later, the colorful coral reefs were dead and grey because the factory near the sea poured waste water into the sea. Jacques Cousteau decided to tell people how important it was to save the environment under the sea. He started the“ Cousteau Society ” to help protect life in the sea. Now there are over 30000 members all over the world. Since water covers most of the earth, Cousteau knew that we should keep the sea clean. We should not litter the sea, and should clean up the dirty parts. As water is very important to our environment, he encouraged everyone to take part in protecting our lakes, rivers, sea and ocean.

There are still a few people who are not protecting the water now in the world. For example, some factories pour waste things into the rivers, lakes or into the sea near by. The water there has become very dirty and we can’t use them at all. Although there are seventy–five per sent of water in the world, we can only use fresh water, that there is only a little. So we should use little water when we need to use it. For example, I do not use too much water when I am washing my face or having a bath… It is important for us to keep the water clean. You may ask yourself, have I ever poured or thrown dirty things into the water? If your answer is “No”, that means you have already helped to protect the environment. It is our duty to protect the environment. You may ask yourself again, have I ever helped to clean up the water? If your answer is “Yes”, that means that you have already done something useful to improve the water. If we use up all the water, it is difficult for us to get it from anywhere, including the universe. It is terrible to think that people are too thirsty to live! I believe, that if everyone helps to protect the water, the water must be protected. You do not want to “kill” your son or your grandson, do you? So now let us to protect the water! Please don’t let the last drop of water on the earth is we human’s tear!

Environmental Pollution

Write a passage with the words and phrases given:

the problem of pollution, cause, artificial substances, release, waste products, industrial production, consumption of goods, bring it under control, agriculture, chemical substancea.

Environmental Pollution

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial

production and increased consumption of goods. Bedsides, the use of chemical substances

in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

环境污染

最近我读了一则消息说在日本，许多商人向顾客出售新鲜空气，现在这种情况越演越烈，Environmental Pollution-环境污染，四六级写作《Environmental Pollution-环境污染》。为什么呢? 因为在日本新鲜空气越来越少，在美国也是如此。

事实上，环境污染是整个世界正在面临的一个严重问题。这主要是由于人造物质，工业生产过程中所产生的废料以及消费商品的增长造成的。另外，在农业中使用化学物品也造成了环境污染。看看天空，你可以看到浓烟从高大的烟囱中释放出来，这些脏而有毒的物质流入我们赖以饮水的河流，数百万吨废物正堆积在我们周围。

怎样改变这种状况呢？越来越多的国家正在试图拟定出一些有效措施控制环境污染，但至今成效不大。

[环境污染英语作文附翻译

Harmony with the environment is that we live in on Earth,who is a natural son,and not only to natural persons as the conqueror,as we all know,there is only one earth and the mountains on Earth,the animals.Plant human cells,if it damaged,destroyed nature organizations,to the eradication of mankind.Therefore,the environment must be linked with social ethics,character education and practice acts as an important element of it.Everyone must fulfil its responsibilities and obligations to protect the environment.

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

At present, the reform and development of our country is at a critical juncture, and we should strive to achieve the goal of building a moderately prosperous society in all respects. But there are still some problems -- our living environment is seriously polluted; And the green resources are falling.

We do a lot of what the environment, such as: on one occasion, in a clean small garden, there have been some rubbish, gradually where there are a lot of people throw garbage, there is a garbage dump. It turned out that the trees were green and the flowers and grass were blooming. The bees and the butterflies were there, and there was a smell of enchantment. But now, there was nothing to do with it, and the smell of it was so bad that no one was willing to stay there any longer. Alas! It is a pity that such a beautiful garden is gone. If people notice that they dont pollute the environment, now, by the way, its a kind of escape. And, what a wonderful thing for people to have a rest and take advantage of the cold. But now its a junkyard, and the consequences of polluting the environment are terrible.

And there are a lot of factory waste is also pollute the environment, but the most serious is the pollution of water, I heard of such a story: there was a village, there was a clear pool. There were lotus flowers in the water and the goldfish, and it was so beautiful that visitors to the village would not forget to take a look at the scene. And people in the village wash and cook and drink water and water, so the water is very precious. One day, a businessman opened a factory near the pond, and the factory shut down a lot of waste water and garbage and went into the pond... The result can be imagined: the goldfish died, the water side became the sewage, the tourists no longer came, the people in the village moved away... Alas! The little pond has disappeared. The factory severely polluted the environment and made the environment in the village very bad and affected peoples lives. Its a story, but there are a lot of these things in everyday life, and the results are very serious, not just simple consequences.

In fact, there are many things that can seriously pollute the environment: litter, spitting, grass and so on. The consequences are severe. But the waste of resources cannot be ignored. The worst is the waste of water.

Now, Beijing is a city of severe water shortages, but there are a lot of people in the waste water, such as: there are a lot of people out of the water to wash the dishes and laundry water and reuse. In fact, although can only save a little water, economy is a lot of!

Also, people who sell fish in the market love to put a faucet on the side of the water, and when they use water, they will let the water flow freely. How much water they would waste if they went on like this!

The drink, the wine, etc., are now made with water. Some factories use a lot of water, so some of the water is wasted. Thats a lot of wasted water. This water can do a lot if you save it! You can also avoid a little water.
