环境问题的英语作文(优秀20篇)

When it comes to the environment, most people believe that now is in the shake head to sigh: water pollution, dust storm raids, white garbage everywhere... However, more and more people just sigh, but no action. Only when the sky is no longer clear our heads, remembered that should protect our environment? When we were at the foot of the land into desert, just regret not cherish the nature? I want to say, no, we can all start from to protect our school environment, from the small start bit by bit.

Go to school that day, I and several classmates said and laughed to sit into the corridor, see at a distance a cordial and familiar figure, when we miss zhao. Suddenly, she paused, with his head down as if found any. All of a sudden, she crouched down... Strange, she do? Is to tie his shoes? Or a sprained foot? We havent stepped forward, but she from his pocket a piece of facial tissue, hand a pinch, picked a piece of chewing gum on the ground up, wrapped up, and then threw it into the dustbin. She turned around and saw us strange eyes, smiled and said: "not surprisingly, dont say the whole school, even if lets class, if a person a piece of gum, we will be glued here. If everyone take good care of our environment, we can live in comfort."

Miss zhao said good, do better. I think I did pretty good also. For example, our class classroom environment, there are flower, grass, helped my contribution! Since as health group leader, I work hard, meticulous work. If I was in this respect "xiao-he only expenses furore," then I class "plant corner" career for me, but made great contributions

In modern society, we tend to become more and more aware of our living environment or physical environment, because we are not clean as before. So many people now choose their house as to its environment but not its location and expenses to afford it. As we all know, the environment pollution is more and more serious during these years, what we could do is to make great efforts in protecting environment gradually. As to government pollution, as to common people. We also try to protect it and make it remain clean. Although we have managed to protect the environment to a certain extent. It is still a very long way to go.

Protect our enviorment The earth is our home,we must take care of it.We shoule make a less pollution as we know everybody in north America makes 1000 kilograms of the garbage everyday. Most of it is packaging Most of garbage turns into soil but not to plastic,plastic keeps for many years it will pollute our environment so we shouldn’t waste thing we should make some things for recycling .

在现代社会中,我们往往更加了解我们的居住环境还是自然环境因为我们不干净如故.现在这么多人选择它作为自己的房子,而不是它的位置和环境费用负担.众所周知,环境污染日趋严重,这些年来,我们可以做的是努力保护环境,逐步实现.至于政府的污染,为百姓.我们也设法保护它,使之保持清洁.虽然我们已能在一定程度上保护环境.它还有很长一段路要走.

保护我们的环境 地球是我们的家园,我们必须照顾好它我们应该使减少污染,如我们所知大家在北美的垃圾进行1000公斤。大多数都是包装大部分垃圾变成土而不是塑料制品,塑料保持多年来它会污染我们的环境,所以我们不应该浪费我们应当做些事情回收利用。

Students, we hope that the motherland can become pure and quiet sunshine, fresh air, such a beautiful and desirable country. How we need such air, how much we love the environment!

As a new generation of Chinese people, we should always cultivate environmental awareness and worry about our country. Some students, however, do not cherish the paper, only to tear up several sheets of paper at the beginning of a composition. Trash and see if there is an opportunity to the school, where two-thirds of all kinds of waste paper, in order to make the paper, we paid a heavy price, consumes large forests. Schoolmates, when we light this pile of paper, our hands shake, and through the light of the fire, we see a piece of green wood.

How should we protect the environment?

First, love nature and be the little leader and little propagandist who protects nature. We should love the grass and trees of the campus and the streets, and strive to be the guardians of the garden. We should not only understand the natural balance of nature. We should also promote the environmental protection of natural environment to students, society and families.

Secondly, starting from me, from now on, protect the surrounding sanitation. Do not spit, pick flowers, do not destroy trees, forests, waste paper, etc. Although our strength is limited, if everyone can start from me and start from now, then our environment can be improved.

Thirdly, we should study the knowledge of culture and science carefully, and make a great effort to protect nature from m. We in the primary school to learn scientific and cultural knowledge, grow up, with our wisdom and hands control waste water, waste gas, waste residue, mountains and desert to governance, to improve soil and water quality. I believe that our home will be better in that time.

Students, for the better of our homeland, make a move!

a country maid was walking along with a can of milk upon her head,when she fell into the following train of reflections."the money for which i shall sell this milk will enable me to increase my stock of eggs to three hundred,these eggs,allowing for what may prove addle,and what may be destroyed by vermin,will produce at least two hundred and fifty chickens.the chickens will be fit to carry to market just at the time when poultry is always dear;so that by the new year i cannot fail of having money enough to purchase a new gown.green-let me consider-yes,green becomes my complexion best .and green it shall be, in this dress i will go to the fair,where all young fellows will strive to have me for a parter;but no-i shall refuse every one of them,and with a disdainful toss turn from them."

transported with this idea,she could not forbear acting with her head the thought that passed in her mind,when down came the can of milk!and all her imaginary happiness vanished in a moment.

girl who sat next to me was reading a book, which caught my attention. I asked

her about the book, I found that I had read it before and then we discussed

about the novel. We talked happily, when the train arrived, we got off together.

When we got aparted, we promised to keep in touch. We communicated by the

computer. Now a year has passed, we become good friends and I miss her all the

time. She is a genuine friend. I plan to go to Guilin again and then we will

meet.

Water pollution on the impact of industrial and agricultural production of industrial and agricultural production not only need to have enough water, but also have some requirements for water quality. Otherwise, the industrial and agricultural industry will cause great losses, especially in the industrial and agricultural production process using contaminated water, the human has a great harm. First, the destruction of industrial equipment, a serious impact on product quality. Second, the chemical composition of the soil changes, fertility decreased, leading to crop reduction and serious pollution. Third, the city to increase domestic water and industrial water treatment costs.

Clean air is the necessary material basis for people to survive, an adult to breathe an average of 15 cubic meters of air a day, if people breathe heavily polluted air, no doubt harmful to health. Therefore, the study of the impact of air pollution, awareness of the value of clean air is a very complex frontier research project. And children in the growth and development stage, is the most sensitive to the outside world air pollution, the study of air pollution on children more likely to obtain valuable results. Based on this, the Chinese Academy of Engineering, China Environmental Monitoring Station Chief Engineer Wei Fusheng for the Chinese chief scientist of the Sino-US scientific and technological cooperation projects one by one air pollution on the impact of human respiratory health research, in Guangzhou, Wuhan, Lanzhou, Chongqing and other cities and suburbs The results showed that 8196 questionnaires were used to investigate the pulmonary function of children in the air, including environmental monitoring data, and about 3 million data were obtained. After statistical analysis, Air pollution has a quantitative understanding of the effects of human respiratory health (especially children). The results confirmed that the impact on human health to the fine particles of air pollution is most serious (China has 2/3 of the city exceeded), followed by sulfur dioxide pollution (1/3 of our city exceeded), the impact of nitrogen oxide pollution relative Weak. It can be said that fine particles (respirable particulate matter) is the first killer of human health. According to experts, particulate matter attached to the toxic heavy metals, acidic oxides compared with the soil enrichment hundreds of times, thousands of times, or even tens of thousands of times, and can float in the air up to several days, harmful substances with the inhalation Particles into the human lungs, and may through the alveolar into the blood, directly endanger human health.

Recently, the eight-year research results in Beijing adopted by the State Environmental Protection Administration presided over the expert appraisal. Experts believe that this research results for our understanding of the importance of clean air, improve the public and the leadership of environmental awareness is of great significance. The data of the research results provide a scientific basis for the national air environment legislation, the development and revision of air quality standards, emission standards and air pollution control policies.

November 11 is Bachelor’s Day, it is a joke that shopping can make up the

loneliness on that day, the manufacturers sense the great business, so they give

great discount on that day, people are attracting by the discount, they buy a

lot of things on that special day. But we known that people lose their wisdom

when they buy things, most things are useless.

Today, shopping online brings great discount, the price of the product will

be cheaper online, so people like to shopping online. When the holiday comes,

the products even get cheaper, customers always wait for the chance to pay the

lower price. It is said that as so many buy things on Bachelor’s Day, the

express delivery congested, customers got their stuff very late. It is more

ridiculous that a couple divorced because the wife bought too many things

online.

Now December 12 is coming soon, the discount is being presented, it is a

great lure that customers can’t control themselves. Shopping online should be

rational, we just buy what we need, the rest even is cheaper, but without value,

we must realize is a waste.

Now, we can get cheaper stuff not only online, we should control ourselves,

we buy what we are using, we can use the money to do meaning thing.

From this cartoon, we can see that at the top end of the river,is a chemical factory and a paperrnaking factory which send out and poisonous wastes. And the river has been seriously polluted,n be seen from the color of it. Along this "black" river, there area few people selling fresh water which must have been taken from far away places.

At the first glance, it is very strange to us how can people sell water along the river, but this is the case, because the water in this river is undrinkable. This presents a serious social problem--environmental pollution. With the development of economy, our living standards have been greatly improved. But we can＇ t ignore the fact the air we take in and the water we drink today are not as fresh and clean as they used to be. Some kinds of pollution can even be deadly to people. It is high time that we took some measures to solve the problem.

I think we can first call people＇s attention to this problem so that they will be aware of the serious consequences of it. Then,we can pass certain laws to restrain the factories from sending out wastes. Finally, we can do more resarch work to find out ways to deal with the wastes.

Keep Square Clean, Tidy On Sunday, still on display on Tian＇anmen Square were dozens of floats that were paraded along Chang＇ an Avenue during the NationalDay celebrations. Thousands of people strolled on the narrow lanes be- tween the floats that fragmented the square, busily taking photos. Not far from the noisy crowds, yellow leaves fell nonchalantly from locust trees along the driveway, sending out the first signals of the coming autumn. But even if all the leaves fall, they still cannot cover the brown and black spots on the hitish stones in the huge square.

Such stains of chewing gum, stale oil or some worse blemish have remained a constant pain for city cleaners since the square ＇was re-opened a few months ago after renovations to celebrate the 50th anniversary of the founding of the People＇s Republic of China.

Few renovation project planners likely foresee this discouraging outcome. Originally, they merely intended to give the city a facelift. The square was indeed impeccable when new: The-white terrazzo surface not only looks clean but it was made with materials that help prevent it from becoming slippery.

However, as time goes by, the virtue becomes the vice: the surface attracts and accentuates dirt. As a result, China＇ s most high profile site has to suffer the indignity of being paraded daily efore thepublic in a humiliation state.

While the tourists who litter should bear the bulk of the blame, the renovation designers should also have learned something: including the square＇s sanitary maintenance issue into their consideration.

写作题目

Individuals can do nothing to improve the environment; only governments and large companies can make a difference. To what extent do you agree or disagree?

范文

Nowadays, an increasing number of people are concerned about environmental protection and regard it as one of the most important challenges. However, whether only governments and big firms have resources and powers to preserve our environment is a controversial issue. My view is that every single citizen could also make a huge difference.

In the first place, it is clear that it is human activities that have the greatest impact throughout the history. Both environment contamination and conservation are the long-term process, and no single government or big company can meet this challenge alone. So whoever created the problem should be responsible for solving it; environment protection needs every one of us to continuously participate in.

Moreover, the publics wills and behaviors have critical influence on governments policies and companies strategies. For example, if everyone says no to plastic shopping bags and paper cups, the companies that manufacture such products will switch to environmental-friendly substitutes in order to survive in the market.

保护学校环境（二）

The protection of the border is not a new problem for us, and our government has long proposed clear targets for governance. As every ordinary person in real life, although it is impossible to work directly in environmental protection, we can start from small things and start from me. Can you raise your hand when you see the tap in the bathroom? When the battery runs out, can you classify it instead of throwing it away? How about when shopping doesnt use ultra-thin plastic bags? ...... Small things are small, but they reflect how much environmental awareness we have.

Recycling one ton of waste paper can regenerate 800 kg of paper, can save 17 tree. 20 waste recycling boxes can create a beautiful pen container. Recycling one glass bottle to save the energy, can make the bulb light for four hours. Recycling one aluminum can is to save the half oil cans. So we should place the garbage classification, reproduction by the relevant department after recycling reuse!

As long as we start from oneself, starts from the minor matter, everybody joint efforts, perseverance, we will be for the society, also a piece of clear water, blue sky for yourself, I hope everybody can voluntarily protect the environment, to make our environment more beautiful life.

境保护对我们来说并不是一个新问题，我国政府也早就提出了明确的治理目标。作为现实生活中的每一个普通人，虽然不可能都直接从事环保工作，但我们完全可以从小事做起，从我做起。当看到洗手间的水龙头在滴水时，是不是能够举手关上呢?当电池用完后能否分类收藏处理而不是随手扔掉呢?当购物时能否自觉不使用超薄塑料袋呢?……一件件小事虽然都很不起眼，但却体现我们究竟具备了多少环保意识。

回收1吨废纸可再造出800千克好纸,可以挽救17棵大树.回收20个废餐盒可以造出一个漂亮的笔筒.回收一个玻璃瓶节省的能量,可使灯泡亮4个小时.回收1个铝罐就等于节约了半个铝罐的石油.所以我们应将垃圾分类安放,由有关部门回收后再生产再利用!

只要我们从自己做起，从小事做起，大家共同努力，持之以恒，就一定能为社会、也为自己留下一片碧水蓝天，我希望人人都能自觉保护环境，让我们的生活环境更加美好。

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.

The environment is the harbor of the mind; The artist said: "the environment is the source of inspiration. The military says that the environment is the key to success. Educationalists say that the environment is the cradle of creation. Students say: the environment is a necessary condition for our study. Each of us is the master of this campus and has the duty and responsibility to safeguard the campus environment.

The quality of campus environment directly affects the work, study and life of teachers and students. Nowadays, on our campus, we still have the food packaging bags, scraps of paper, and beverage bottles scattered by our classmates. Every time the wind blows, the rubbish will dance on our campus, all of which is out of proportion to the green environment on our campus. "Campus is my home, cherish the people", believe no teacher, the classmate hope to learn in the environment that rubbish everywhere, life.

So from now on, we should take good care of the campus environment and conscientiously maintain the cleanliness and hygiene of the campus. Develop good hygienic habits, and make the rubbish into bins and bagged garbage. Pick up scraps from the ground at any time, throw them into the trash, make sure the ground is clean, and remind and stop littering. Take good care of the campus public goods, not messy painting and so on.

However, the reality is very cruel and in our campus, always can see some disharmonious white trash, always can see the ground of debris-brick, I sad for it.

Today, who is destroying our campus environment, who has taken away the beauty of the campus? Everyone should know that it is us who destroy the campus environment. There are a lot of students who learn to "paint" on a clean wall. These bad behaviour, has attracted many students, however, we are always at the bottom of the moan, hardly anyone can bent down and picked up the ground of debris-brick; Few people can voluntarily erase the footprints on the wall.

I believe that as long as we everyone involved in protecting the environment, our campus will be bright blue sky, the wall of our campus more white, our campus will be beautiful and clean.

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 our daily life, we often leave the tap on after cleaning hands. Sometimes we often drop litter in the river. So the water was polluted by us. I think we could use a bottle of water two or three times. We have to turn off the tap after cleaning hands.

Let’s try to form a good habit and save things around us. Let’s do it from now on!

Fish can’t live without water. Plants can’t live without water. People can’t live without water, either. As you can see, the water is very important to us. But now drinking water is leand less. The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do nowI think we can plant trees, clean the banks of the river, water the plants by using used water. Turn off the shower while we are washing hair. And we shouldn’t drop litter into the river and so on.

It’s our duty to try our best to protect and save water. And don’t forget that if we don’t save water, the last drop of water will be our tear

让我们试着养成一个好习惯，把东西存起来。让我们从现在开始!

鱼离开水就不能生存。植物没有水不能生存。没有水，人们就不能生存。正如你所看到的，水对我们很重要。但现在的饮用水是少少。水被严重污染了。

所以我们将迅速采取行动以节约水，但是我们必须做什么我想我们可以种树，清洁的河岸，浇花用的水。我们洗头发的时候关上淋浴器。我们不应该把垃圾扔到河里，等等。

尽我们最大的努力保护和节约用水是我们的责任。别忘了，如果我们不节约用水，最后一滴水就会成为我们的眼泪。

Nowadays environmental protection has become the first thing we have to do, because now the earths environment is under threat.

Now, we know that the earth has been warming, cold place has melted the ice, the water level becomes more and more high, let many coastal countries. More land desertification, disasters are hit, make our life is no longer so carefree.

First of all, we must start from the side.

Forests have been cut down, automobile exhaust emissions... The first will directly affect our lives, because they let we dare not breathe. So, the best way to deal with these problems is to drive less, ride bikes, and riding a bike is good for you! . But although it has been said that and said more than once, but why there are so many cars on the road? So, this method really, a bit not practical.

The simplest is to plant trees, the trees are humans good friends, they can help mankind to many things, such as clean air, and so on. So, a variety of trees, this method is very practical!

In short, our earth wanted us to take good care of yourself, to protect, want to use practical actions to help the earth, make the environment more beautiful!

先如今环保已经成为了我们必做的事，因为现在地球上的环境正受到威胁。

现在，我们知道地球已经开始变暖，寒冷地方的冰已经开始融化，变成的水使水平面越来越高，让许多沿海的国家被淹没。更多的土地沙漠化，天灾不断来袭，使我们的生活不再那么无忧无虑。

首先，我们必须从身边做起。

大片森林被不断砍伐，汽车尾气不断排放……这些首先就会直接影响到我们的生活，因为这些让我们“不敢呼吸”。所以，这些问题最好的解决方法就是少开车，多骑自行车，而且，骑自行车也很有益身体健康!。可虽然一直这样说，而且说了也不只一次，可为什么还是有那么多的车在路上呢?所以，这个方法实在，有点不实用。

最简单的就是种树了，树是人类的好朋友，他们能帮助人类许多事，比如净化空气啦，等等。所以，多种树，这个方法很实用!

总而言之，我们的地球要我们自己去爱护，去保护，要用实际行动来帮助地球，让环境更美好!

Nowadays, house husband has become a hot phenomenon in modern society. As

we all know that no matter what country, it’s a tradition that men play a core

role in family who always take the burden to earn money to support their family.

But things are kind of different as society develops, more and more men are

beginning to take over housework while women go out from house. In my point of

view, I think this is not a big deal.

In the first place, house husband may be a shame title for men, but when it

comes to money, there is no room for reputation. As society develops, the life

standard are rising, and everything for living is much expensive than before, if

couples want to guarantee their life quality, then they should let the one who

earn better to work, although the one is female.

In the second place, it’s fine for women to support family as long as they

earn better than men. In the past, women always were treated very badly, and

they got no rights to be educated, to work. In some countries, they can’t even

show their face to others. A traditional female role is to stay at home, taking

care of children and do all of the housework. But now, lots of women have a good

job, so that they totally have the ability to be the economic backbone.

Therefore, in order to take good care of family, men are likely to stay at home

to do housework. I don’t think it’s a shame for men, because no matter what you

do, as long as you do it well, you are successful.

To sum up, people should change their opinion about core role of a family.

It’s acceptable for women to support the family, and there is no shame for men

to do the housework. As long as you remember life quality comes first.

Nowadays, an increasing number of people are willing to serve as volunteers

especially the university students in that they consider that volunteering is

not only a great contribution to our society and those who are in need, but also

improves themselves in many aspects.

For one thing, there is no doubt that volunteering makes contribution to

our society and people in need. The volunteers provide their assistance without

requiring any financial rewards. Their contributions have a great impact on

harmony society contribution.

For another, serving as a volunteer is also beneficial to the volunteers

themselves. They can improve their communication skills when providing help for

others. One of the examples is that the university students who serve in Canton

Fair will get a great chance to practical their English and get in touch with

different kinds of people as well as broad their horizon. In addition, by

serving as different kinds of volunteers, they are easier to understand

themselves and know in which fields they are interested.

In a word, volunteering has brought many benefits to our society, those who

are in need as well as the volunteers themselves. Therefore, let us enjoy the

time when serving as a volunteer.

Dear headmasters,teachers,classmates and friends:

I’m very proud that I have chosen to speak to you all today, I’m a bit nervous as I’ve never made a speech before to so many people ,so please forgive me if it shows.

As we all know,the environmemt around us is getting worse and worse .In some places we can’t see fish swimming in the river or trees on the hills. Some people even have no clean water to drink. So I think we must do something to protect the environment. .But what can we do? How to protect our environmemt ?For example ,we can go to school on foot or by bike . we can use shopping basskets not plastic bags .when we go shopping and we can use both sides of the paper when we write .In a word ,if everyone pays more attention to our environment ,there will be less pollution and our life will be better.

“There is only one earth”,I hope everyone will protect our environment well. Thanks!

同学们，我们现在的生活过得是越来越好了，几乎所有的人们都过上了幸福快乐的生活，人们安居乐业。

但是，当你有一天行走在宽阔的道路上，欣赏着旁边的緑树红花，突然闻到扑鼻而来的是污水的臭味时，你不觉得恶心吗?当你心情无比舒畅的走在干净的校园里，突然一个塑料袋飞到你的脸上，你不觉得扫兴吗?相信同学们也有同感。人类和动物的生存环境已经受到严重的破坏。使许多珍贵的动物面临灭绝的危机。所以保护我们唯一的地球，保护我们的家园，是我们这一代青少年的责任。

我真想对那些破坏环境的人大声的说一句：“请停下你们的行为。”虽然我个人的“力量”很弱小，但是我可以号召所有的同学们一起和破坏环境的人做“斗争”，来净化我们的家园。还人类和动物一片干净的蓝天。让小朋友们在阳光下茁壮成长，让鸟儿们在天空中自由飞翔。

在这里，我再一次号召同学们从个人做起，从我做起，不要乱扔垃圾，不随地吐痰，爱护花草树木，节约用水用电。坚决和破坏环境的人做“斗争”做一个环保“小勇士”。
