环境污染话题英语作文（通用20篇）

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.

阳光明媚的早晨，我坐在草坪上，一边倾听着鸟儿的鸣叫，一边喜滋滋地望着报纸的头条傻笑。如果你听到了这个喜讯，也一定会为我喝彩的。那就是本人设计的一款环保节能汽车获得了科技创新一等奖。 The sunny morning, I sat on the lawn, listening to the birds tweet, while looking at the headline of the newspaper with joy.If you hear this good news, you will definitely applaud me.That is, an environmentally friendly energy -saving car designed by himself has won the first prize of scientific and technological innovation.

这种环保节能汽车包括了飞机、直升机、汽车、电动汽车等功能。首先要介绍它的第一大特点“飞”。我们常能看见马路上交通拥挤的现象。这时你就可以驾驶着环保节能汽车飞过这拥堵的马路，或在天空暂时停留。那你一定会担心：汽车在天上飞来飞去，会不会造成什么不良影响。这个问题你可以放宽一百二十个心。它的外壳是用钢化隐形玻璃制成的。只要按一下“隐形”按钮，它就会立刻“隐身”起来。不过坐在驾驶室里，透过玻璃却能看见外面的世界，也能看见外面的隐形汽车。

那你一定会担心：汽车在天上飞，如果遇到刮风下雨天可怎么办呢?这个问题就是环保节能汽车作用的精华所在。它的外壳如钢铁般坚硬，不仅大风刮不倒，也可以发出电磁波阻挠雷电的攻击。这样你就可以放心大胆地在天空翱翔。

忧心忡忡的你一定会有新的问题接踵而至：既然是环保节能汽车，那节能、环保又体现在哪儿呢?这种汽车内部安装有太阳能发电机、风力发电机、吸收二氧化碳发电机可以提供能源，所以你不用担心能源耗尽的问题。

环保节能汽车在天上飞、在地上跑都是不会发生交通事故的。在环保节能汽车的周围有一层隐形的防护罩。这种防护罩只有在汽车启动后才开始保护。这种防护罩以汽车的长为直径到汽车的顶部是一个半圆。如果有障碍物触碰到了防护罩，那汽车将会立刻自动躲闪。

我相信这种汽车一定会受到人们的广泛欢迎，为人类生活提供更多方便。

I have my own room.It is big and nice.There is a bed,a desk and a shelf.The doll is on the bad.The lamp is on the desk.The books are on the shelf.The trash bin is behind the door.The clothes are in the closet.There is a air-conditioner over the closet.Look!There are many pictures on the wall.I love my room very much.

There are more high-rise apartment buildings built in the city we live to accommodate more city dwellers. To make room for these constructions, a large number of trees are cut down. We have to be constantly afflicted with the noise and air pollution everyday. Obviously, we are paying the cost of the development.

Even the most developed countries are troubled with environmental issues. In fact, the more developed the country is, the severer the problem has. To maintain our economy prosperity and stability, we have to be in full operations and spread the workload in industry fields. As a result, we may seek temporary economic development at the expense of the environment and resources. The consumption of natural resources has been a big problem. It is admitted that the world economy is booming with the satisfaction of environment. However, we have made a blunder by equating material prosperity with better living standards.

A better life should be a life closer to nature. The modern lifestyle is best characterized by hectic, mass-productive and seemingly comfortable. But actually something originally natural and invaluable has been lost. We are no longer able to breathe fresh air, take a walk in the woods or even look at the stars in the sky as the stars are obscured by smog and artificial lights.

Hence, we need to curb the quick tempo of life in order to protect our environment and ironically improve our life. Science and technology thus should be employed to create a harmonious relationship between mankind and nature. A better environment means much more than material comforts. Besides, by slowing down a little bit, our life would turn out to be less stressful. To have a better life, we need take effective measures right now.

The current environment damage stems from the misguided conception that material wealth is equivalent to a better life. In reality, environmental protection serves as the catalyst of our very pursuit of better life rather than a deterrent 关于环境保护的英语作文2

Many people believe that we have developed into a “throw-away society” which is filling with plastic bags and rubbish. What do you think?

Wind blows up bags higher and higher in the sky. It is a scary thought that some day the earth will turn into a huge garbage land. Wastes, if not treated properly, will make our life a living nightmare.

The environmental issue is getting worse almost every day in cities with very large population. As is often the case, city development outpaces environmental protection. People consume great amount of natural resources and produce wastes. To effectively address such problems, cities need to spend big money. In addition, they need to call to the attention of people to become more environmentally responsible.

Many people are becoming less responsible and easily influenced by bad behaviors. “Why should I care while others shouldn’t?” Such idea makes some people only concern with places where they live and work. Furthermore, people sometimes even purposely litter for revenge to other people.

Although media promotes environmental awareness, good people are often snubbed as posers who try to set up a superior image in real life. Consequently, they are intimated of receiving negative comments for doing the right thing. Wrong as it is, such phenomenon is widespread especially among youngsters and people with low income and little education.

However, our society is waging a campaign against environmental pollution. People learn the harms of un-degradable lunch boxes and other polluting wastes. Laws in many countries prohibit or limit excessive use of polluting bags. Companies are continually replacing the old materials with more environmental friendly and recyclable kinds. Scientists have developed more effective technologies in waste treatment. As time goes by, more and more people put high priority on the protection of environment for a healthier life.

To sum up, people produce huge amount of garbage and the environment is seriously polluted because of lack of financial resources, sense of responsibility, or efforts. But the world will not turn into a “throw away” society if people put in sufficient efforts to protect our environment

Today the quality of our natural environment has become an

important issue. The world population is rising so quickly that the world has become too crowded. We are using up our natural resources and at the same time polluting our environment with dangerous chemicals. If we continue to do this, life on earth cannot survive.

Concerned people have made some progress in environmental protection. Governments of many countries have established laws to protect the air, forests and sea resources and to stop environmental pollution.

Still more measures should be taken to solve environmental problems. People should be further educated to recognize the

importance of the problems, to use modern methods of birth control, to conserve(保存） our natural resources and recycle（再循环） our products. We are sure that we can have a better and cleaner place in the future.

When we talk to other people, we will be pleased to chat with them if they are nice to us. On the contrary, if the person is rude and impolite, we will not want to listen to them. Manner matters so much in the communication. It reflects what kind of person we are. We need to form the manner and make us a polite person. First, we should be considerate. When people talk to us, we should think of the problem in their position, so that we will be patient and understand them. Second, we should not speak rude words. Impolite words will destroy the good impression. Manner is the mirror of who we are.

【参考译文】

当我们和他人交谈时， 如果他们很友善，我们就会喜欢跟他们聊天。相反，如果这个人是粗鲁和不礼貌的，我们就会不想听他们讲话。礼貌非常的重要，它反映了我们是什么样的人。我们需要养成礼貌，做一个有礼貌的人。首先，我们应该体贴一点。当别人跟我们讲话的时候，我们应该站在他们的立场想问题，这样我们就会有耐心、理解他们。第二，我们不应该说粗鲁的话。不礼貌的话会破坏好印象。礼貌是反应我们的镜子。

面对“上下天光，一碧万顷”的洞庭湖，范仲淹说“登斯楼也，则有心旷神怡，把酒临风，其喜洋洋者矣”；而面对“阴风怒号，浊浪排空”的洞庭湖，范仲淹又说有“去国怀乡，忧谗畏讥，满目萧然，感极而悲者矣”，话题作文《心态与环境》。这就是不同的环境对心态的不同影响，另一方面，心态也能够影响环境，并且在一定条件下创设环境。

君不见，“出淤泥而不染，濯清涟而不妖”，不利的环境并没有改变君子气节，反而留清白芬芳于人间；“结庐在人境，而无车马喧。问君何能尔，心远地自偏。”陶渊明并没有因喧嚣的环境而心浮气躁，反而能够用“心远”而致“地自偏”的效果，用良好的心态创设美好的环境。反之，如果心态不好，也会“良辰好景虚设”，“暮霭沉沉楚天阔”。在“力尚足以入，火尚足以明”的条件下，如果怀着从众的心态而“随而止”，也会“不得极夫游之乐也”，不会发现“世之奇伟、瑰怪、非常之观”。这说明心态和环境是互相影响的，所以我们在不利的环境中，要发挥主观能动性，化不利为有利；在有利的环境下，要“居庙堂之高，则忧其民”“思谦冲以自牧”。要知道环境影响心态，心态也会影响环境，二者互相作用，相辅相成。有位名人说得好：我们在无法改变周边环境的情况下，可以改变自己的心态。面对浮躁的周边环境，我们有必要学学“心远地自偏”的陶渊明，切不可“扬其波”而“啜其醨”。不但要远离尘垢，而且要改变不利环境，创设美好环境。

君不见，项羽面对敌强我弱的恶劣环境，破釜沉舟，示士卒以必死之心，结果楚军“以一当百”，终克强秦；还是这个楚军，在“四面楚歌”的心理战中，风声鹤唳，土崩瓦解。

这种心理战的功率于今发挥到了极致，球队之间进行心理攻防已到白热化程度，心理素质较弱的球队战斗力会大打折扣。商战中的营销心理学是克敌制胜的法宝。美伊战争中的双方不也都利用了心理战术且收到了实效吗？我国首次载人航天飞行杨利伟在几位备选航天员中脱颖而出，良好的心理素质不正是胜出的必要条件吗？为什么心理素质如此重要？就因为在主观和客观这两大因素中，主观因素发挥着能动作用，在一定条件下会转化为物质力量，。在现代社会竞争中，如果你周边的环境不好，那就要更好的发挥主观能动性，争取事物向相反的方面转化，而不要一味抱怨环境。二次大战盟军一位著名将军在困难面前总是抱着乐观向上的心态。有人问他为什么能够这样，他回答说：“我小时候在家中打扑克牌时，有时为抓到的牌很不好而恼怒，这时我的母亲告诉我，不要抱怨自己的牌不好，而要充分利用手中的几张牌。”

中国有句古话说“运用之妙，存乎一心”，人人手中都会有几张牌，每个人手中的牌又是不一样的，这就如同面对的环境。可以改变的是自己的心态，把现有的优势发挥到极致，从而改变环境。我国航天工业集团有个著名的“三刀师傅”，那是由于他在为一个国防工业关键部件加工时，最关键的只有三刀，多一刀或少一刀，那么几十万人几十年的心血就要付之东流。这位师傅虽然全身湿透，但是仍然用良好的心态圆满完成了任务，这不就是良好的心态转化为物质条件了吗？不就改变了我国高科技环境了吗？高位截瘫的史铁生和只能坐在轮椅中度日的霍金尚且用他们良好的心态为创设美好世界作出了巨大贡献，我们有什么理由不努力改变心态去创设美好环境呢？

现实环境无论怎样糟糕，我都不会沮丧，我会努力调整心态，努力创设美好环境，我不因世界的阴影而苦恼，世界因我的笑容而灿烂。法国作家菲利普·德朗说“目光决定世界。”我要说：“心态创设环境。”

Hello, everyone. I’m am a student in No.1 Middle School. I’m very proud that I have been chosen to speak to you all today.How to protect/save our environment/world?

The environmental pollution is worse and worse /more and more seriously today. Water is polluted ,we have no clean water to drink Many trees are cutting down, some animals is getting less and less.Some factories is poring dirty air in the sky , the population is increasing faster and faster ,resources is getting less and less…etc. Not only does it affect our lives and health, it also has a great affection in the future.

The first fact I worry about is noise pollution. People can"t sleep well if there is too much noise. That"s why so many people prefer to live in the countryside rather than live in the noisy city. I suggest all the factories and cars shouldn"t make terrible noises. If they make terrible noise that isn"t allowed, they will be fined, and we can also produce the cars which can"t make terrible noise.

The other pollution is rubbish pollution. If everyone makes so much rubbish, one day we may live in a world filled with rubbish. Some people throw the waste paper about. I suggest rubbish should be put into different kinds of dustbins or paper bags.

[关于环境污染的英语小作文

人类从诞生之日起，就不断地从大自然中获取资源和能量。从人类发展的历程来看，生产力的每一次重大改革，都使人类的生活水平迅速提高，但同时，也给人类世界带来了严重的环境恶化问题。

环境污染给人类的生活带来严重的危害，我认为，在现代科技发展的今天，我们可以利用科技来解决一些生活中的垃圾污染。

首先，一次性筷子的浪漫是我们国家的一大问题，餐馆里，小巷中随处可见一次性筷子。我们国家最好可以在垃圾箱腾出一小块空间来专门存放一次性筷子，接着最好能把一次性筷子清洗干净，再打成纸浆，重新制作纸张，最好，国家能够不再用本国极为宝贵的森林资源制作一次性筷子，最好能在餐馆中普遍应用家常用的可多次使用的筷子。

对于塑料，一直是人们都很头疼的问题，塑料被自然分解常常需要几十年，几百年，而焚烧则会产生污染空气的气体，对于塑料，我们最好能从根本上解决问题，即塑料的生产材料是一种以高分子量有机物质为分子的制作材料，其实它的成分主要是树脂，我想可不可以不用树脂制作，改用几种植物，最好能利用小草的茎叶来制作，同时，也要专门根据所对应的制作材料找到如何分解的方法，从而不会污染环境。

在家庭生活中经常有很多废纸，扫起来很麻烦。在我们家庭生活中经常用到吸尘器，来把那些细小颗粒，小灰尘吸进去，我们可不可以发明一种吸纸器，大家都知道一些场电体能够吸引轻小的物体，甚至发摩擦带电后也会吸引小碎屑，我们可以利用这个特性，使一些物体带电（自然电荷），放入机器中，参照吸尘器的制作方法，来制造一种吸纸器，这样，一些使人类疼的碎纸问题就可迎刃而解了。

生活中还存在许多污染，它们正一步步侵蚀我们的生态环境，破坏我们的美丽家园，处理污染需要我们每一个人的智慧，需要我们付出与努力，劳动与心血。

为了我们人类能世世代代生活在这美丽的家园，就让我们从现在做起，从一点一滴的小事做起，做护生态环境，建设美丽家园吧！

What is my ideal? This question has been in my mind for a long time. Well, everyone will laugh and say that I just want to be a security guard.

If you dont believe me, I am a small officer who cant reach the 14 products, but if you dont believe me, please listen to me.

Our community is famous for "thieves". I used to have a very good bike, because I didnt have a lock, so I had to stop in the small village. The next day I woke up to the garage, and my car didnt even have a shadow. At first I thought my mother was riding, and then I asked, it was stolen. Another time, we were not at home, the thief even climbed into our house and stole over 500 yuan!

The madness of the thief has made it impossible for the inhabitants to live in peace, so I resolved that I must defend our community when I grow up. I promise you that I alone will never let anyone who destroys the community get away with a precious thing.

Although this position is small, but without security, our homeland will not be peaceful and harmonious.

寒冷的冬天过去了，小燕子和妈妈从南方往以往那个环境优美、空气新鲜的家园飞去。一路上小燕子一会飞到这、一会飞到那，开心地说：“太好啦！太好啦！要回家啦！想想那儿的环境真让我怀念。蔚蓝蔚蓝的天空上，太阳公公每天都对着我笑；一排排树木郁郁葱葱，一阵风儿吹来，它们沙沙作响，就像一位音乐家在演奏；河岸边的小草生机勃勃，最重要的是，在那清澈见底的小河里，有我的好朋友小鱼儿，和它在一起的那些快乐时光，真让我怀念……”小燕子越说越兴奋，高兴地上窜下跳。“小燕子，你别高兴得太早，”燕妈妈心事重重地说，“你看，原来的天空那么的纯洁湛蓝，可现在却有不少的黑斑点。我的直觉告诉我，家里出事了。”

它们飞啊飞啊，终于来到了那条熟悉的小河边，但眼前的景象却让它们惊呆了：原本蔚蓝的天空变成了笼罩着一片片乌云的阴天，太阳公公躺在一个角落里默默地哭泣着，大树没有了以前的生机，小草也低下了头。清澈的小河变成了浑浊的臭水沟，里面还堆着垃圾。

不时的有浓烟飘来，把它们呛得直咳嗽。这时一个哀伤的声音从垃圾里传来：“小燕子……”小燕子一听，心里一惊，这不是小鱼吗？”小鱼，你在哪？”小燕子急切地问。“我在这！”小鱼儿从垃圾堆里探出了脑袋。小燕子急忙飞过去问小鱼儿：“这里怎么变成这个样子？”“哎，都是人类的错啊！”小鱼叹了口气继续说道：“他们在附近建了好多工厂，把污水排到小河里；烟囱里升起的黑烟笼罩了天空，污染了空气；还有些人为了图方便，竟然把垃圾扔到这里！害得我们时时刻刻要提防这些炸弹。”“这些人真是太可恶了！”小燕子愤怒地喊道。“就是就是！”小鱼儿也噘起小嘴愤愤不平地抱怨：“一点都不关心我们这些小动物，难道我们可有可无吗？再说了，破坏环境对他们自己也有害啊！”

小燕子和小鱼儿相互安慰着，它们望望天空、望望小河、望望大树和小草，最后望望那些罪恶的工厂，异口同声地说：“人类啊，救救我们吧，爱护环境也是爱护你们自己呀！”

在十年前的中国，大气污染问题对于普通民众来说可能是个比较飘渺的话题。正如空气本身的性质一样，看不见摸不着却无处不在。而专家学者们则主要关注的是对于工业生产，燃煤发电所产生的硫氧化物的处理和汽车尾气中氮氧化物的处理。十年时间飞逝，随着中国经济的迅速发展，人们生活水平的不断提高，人们开始关注生活的质量问题。与其同时越发严重的正是中国以牺牲环境为代价发展经济所带来的环境问题，其中大气污染问题尤其明显。这几年来关于温室气体和温室效应的话题被讨论得沸沸扬扬，专家们各有其立场，但对于普通百姓来说，全球变暖问题似乎仍很遥远。对于温室气体所带来的全球变暖，海平面上升，冰川融化，动植物灭亡的问题，人们大多数是在电视新闻或报刊杂志上看到，恶劣天气的频发也并不是发生在世界每个角落。相比于温室气体所带的大气污染问题，人们开始关注更多的便是最近发生在北京，广州，武汉等多地的灰霾问题。尤其是在北京持续很久的灰霾严重影响了当地人们的日常生活和身体健康，更是引起了广大专家学者和普通民众的高度关注。而其实对于灰霾现象，国外专家学者很多年前便开始研究。

那么何为灰霾？灰霾是导致近地面大气浑浊的多种空气污染物的混合体。构成灰霾的主要污染物是硝酸盐、硫酸盐、有机碳、元素碳、等固体细颗粒物（PM2.5）和臭氧()、二氧化氮（）、二氧化硫（）、挥发性有机物（）等气态污染物。灰霾往往与天然污染源的排放和二次污染污染物的形成有关，还与一定的气象条件和地形有关。我们现在最关注的同时也最难解决的室外污染物之一是可吸入颗粒物。可吸入颗粒物被分类为两种，直径小于2.5微米的颗粒物（PM2.5）和直径小于10微米的颗粒物（PM10）。虽然两种形式的颗粒物都对人类健康有极大的危害，PM2.5被普遍认为是更危险的，因为它的体积小，大约只有人类头发宽度的1/30。人们在呼吸时，PM2.5可以进入人类肺组织深处，甚至进入血液，造成严重的健康问题。同时更小的颗粒物在大气中可以有较长的停留时间。因此，PM2.5可以传播的更远，停留在空气的时间越长，影响更大的人口。PM2.5和PM10的主要来源包括机动车，电厂和其他工业源，以及生物质的燃烧。其中一个主要的来源是柴油为动力的车辆。这些污染源相结合，可以在城市或农村地区天空一片阴霾，而且往往发生在下午时段。

对于容易形成灰霾的城市,除了城市当地工业污染,汽车尾气的影响以外,特定的地形导致污染物的难以扩散也是灰霾形成的主要原因，像美国的洛杉矶,还有前面提到的受灰霾影响的北京和武汉都受到了地形的影响。洛杉矶市三面被群山包围，当地空气干燥，白天阳光充足。到了晚上，地表面冷却很快。地面附近的空气变冷，而上层空气都比较热，形成逆温。北京市位于华北平原的西北边缘，背靠太行山余脉和燕山山脉，面对辽阔的华北平原，东南距渤海约150公里, 地处暖温带半湿润地区，气候属于暖温带半湿润大陆性季风气候,四季分明，春季多风和沙尘，夏季炎热多雨，秋季晴朗干燥，冬季寒冷且大风猛烈。武汉市则居于内陆、距海洋远，周围地形如盆地，集热容易散热难，河湖多、晚上水汽多，城市热岛效应和伏旱时副高控制明显。通过比较以上3个城市的情况可以发现它们都是较大的工业城市，而且城市海拔较低，周围至少有一面是高地，都分布在低于南北纬50度的地方。这些地区夏季阳光明媚，天气温暖干燥。在城市的盆地地区，逆温现象十分普遍。夏季的阳光使地面温度升高，城市街道和建筑物迅速升温，与炎热的物体表面接触的空气温度升高。通过对流空气向上运动，但它却不能穿透逆温层，因为上面的空气温度更暖且密度更小。空气聚集，但连续的对流形成了垂直的循环，使空气完全混合在一起。从建筑物和汽车废气释放出的气体和颗粒也都聚集在逆温层下，通过对流把聚集的空气彻底混合。这样导致污染物无法快速扩散而聚集，大大增加了当地的污染物浓度。

城市内部灰霾的形成也同样受到了这种类似地形的影响，学者称它为街谷模型。随着城市化的加速，城市及城市周边的自然生态系统逐渐被人工生态系统取代，取而代之的是钢筋混凝土浇筑的高楼与马路,很容易形成城市街道峡谷。这种城市街道峡谷是指两侧有连续，高大建筑物的狭长城市街道空间。在这种地形下,上层大气在进入城市时，风速迅速降低并产生特殊的湍流，使街谷内的流场完全不同于上层大气。而气流对污染物具有显著的运输、稀释、和扩散作用，因此，对城市街谷内污染物的浓度、分布有着很大影响。北京的灰霾现象正是因为污染物积聚难以扩散而导致北京的灰霾持续了如此之久。有相关专家的研究发现,除了通过控制排放源,增大扩散和增加沉积率来降低大气中污染颗粒物的浓度以外,地面的性质也影响着颗粒物的浓度。有研究表明植被对城市空气质量能有接近5%的提高。在城市，尤其是在城市街谷地带种植植被能通过增加沉积作用而降低60%的可吸入颗粒物（PM）浓度和40%的二氧化氮（NO2）浓度。因此，通过对植被的合理利用能过创造一个有效的城市污染过滤膜，对密集城市地带空气质量的提高有着快速有效并且持续性的影响。

灰霾问题不是一个暂时性的问题，相反它是一个长久的问题，从它如何形成，加剧到我们如何解决治理并消除都需要一段很长的时间。

灰霾现象，它只是地球环境污染的一个缩影。我们更应该探究它的根源问题，什么才是它形成的根源，什么才是它加剧的根源。我们没法通过改变天然的气候和地形来解决城市灰霾问题，但我们可以通过减少排放源，通过增加植被，加强城市绿化来阻止灰霾的加剧。人类的不断进步使得人们在追求高科技的同时却忘记了自然本身的无穷力量。越来越高的大楼，越来越发达便利的交通，相反的却是城市越来越差的生活环境。在灰色的钢筋水泥世界里生活久了，人们是否会怀念那晴朗的蓝天，向往呼吸新鲜的空气和在那充满生机的绿色大自然世界里生活。

Cars and Air Pollution

Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars 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 buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

How to protect the environment?

Nowadays, more and more people realize it`s necessary and important to protect the environment. Also,there are some people who don`t pay attention to hygiene and they can`t stop littering the rubbish casually or spitting everywhere all the time.And in addition, there are a few factories often cutting down the trees, discharging chemicals and dirty water and so on.And it causes many problems like the Greenhouse Effect.If they do these day by day and our life will be harder and harder,so we have to stop them. To stop them we can put up commonweal advertisements and tell them the detriment of destroying the environment.So we can start from now to make a beautiful life.

如何保护环境?

现在，越来越多的人意识到保护环境是必要和重要的。同时，也有一些人不`不注意卫生，他们可以`停止乱扔垃圾垃圾随便或随地吐痰的时候。此外，还有一些工厂经常砍伐树木，排放的化学物质和脏水。这引起了诸如温室效应等问题。如果他们天天这样做，我们的生活会变得很困难，所以我们必须阻止他们。为了阻止他们，我们可以提出公益广告，并告诉他们破坏环境的危害，所以我们可以从现在开始做一个美好的生活。

Do you still remember the “Guo Meimei Scandal” which has aroused national fury and mistrust toward Red Cross Society of China in 2011? However, it was just a start of the influence of network public opinion of China in changing the society. Now, nearly every day or two, there will be a new event heatedly commented by Chinese netizens through online facilities.

Actually, network public opinion is the co-product of the interaction between two factors. For one thing, the highly developed internet has brought the explosion of information to everybody’s life. Each piece of information can potentially be an “event”. For another thing, democratic consciousness has grown stronger in minds of Chinese people. Network is the democratic outlet where their free speech can be fully realized.

在一片茂盛的丛林里住着许多小动物，它们每天自由地生活、歌唱，别提多快乐了。可日子一长，丛林里的垃圾越来越多、青草越来越少：小松鼠在树上边啃边扔下的松果核；小白兔到处啃青草，连草根都吃得一截不留；野猪随处大小便；老虎吃了一半的食物……时间一久，那些东西便发出了阵’阵恶臭，招引来无数的苍蝇和蚊子。动物们纷纷向环境保护协会提出了抗议。

为此，青蛙会长召集动物代表进行了一场有关如何改善生活环境的会议，青蛙会长坐在生椅子上慢悠悠地说：“朋友们，最近大家都反映丛林的生活环境很差，我经过调查发现问题还是在于大家，比如说野猪……”

“这不能怪我，我们一直以来都是随便找个地方解决大小便的。”青蛙会长的话还没说完，野猪就红着脸大声吼叫起来。

“可现在不行了，你们数量众多，每只都这样，对环境的污染太严重了！”小白兔们大声喊道。

“胡说，难道只是我们的错？猎狗也时常这样，凭什么只说我们？”野猪龇着牙，怒气冲冲地跳起来，“再说，你们这几只小东西，别以为自己长得可爱就可以到处啃草皮，丛林里的草皮越来越不像样了，不是你们干的，是谁？”

“野猪，你别冲动！”啄木鸟出来劝说。

“你！破鸟，待一边去！尖牙利嘴的，连树皮也不放过，你有什么资格发言。”野猪可能是急红了眼，破口大骂起来。

“啪！”会场突然安静了下来，原来是青蛙会长扔了一张大口罩在野猪的大嘴上，那是一张神奇的口罩，只要一捂到嘴上，就要过两个小时后才会自动脱落。

野猪涨红了脸，拼命地撕扯口罩，却怎么也扯不下来，只能气呼呼地坐着一言不发。

会议进行了很久，动物们总是相互指责，青蛙会长的神奇口罩飞了一张又一张，最后所有动物的嘴都被牢牢地捂了起来。会场再也没有吵闹声了。青蛙会长也累了，躺在椅子上睡着了。

最终会议没有取得任何进展，动物们仍然我行我素，丛林里的环境依旧一日不如一日。后来不知从哪一天开始，动物们都陆续搬离了那里。那片丛林成了一片垃圾场。

染色馒头the industrial dye of steamed bun 毒奶粉the notorious milk powder

It is universally acknowledged that the safety of food is closely related to our health. As the famous saying goes, “we are what we eat.” However, things often go contrary to our wishes since we are faced with a series of food safety problems at present, ranging from the industrial dye of steamed bun to the notorious milk powder.

There are several reasons for this severe problem. First and foremost, many manufactures produce fake food of poor quality in order to get higher profits. In addition, the relevant laws and regulations are imperfect and even ineffective. Last but not least, the public especially customers from poor families, are not alert enough to the safety of food.

In view of the seriousness of the problem, effective measures must be taken to improve the situation. Firstly, it is essential that relevant laws and regulations on food safety should be enforced. Secondly, the relevant department should attach more importance to supervising监督 the manufacturers.

导语：端午节是中国的传统节日，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!

Dragon Boat Festival， often known as Tuen Ng Festival or Duan Wu Festival， is a traditional Chinese festival held on the fifth day of the fifth month of the Chinese calendar. It is also known as the Double Fifth.[citation needed] It has since been celebrated， in various ways， in other parts of East Asia as well， most notably Korea.

The exact origins of Duan Wu are unclear， but one traditional view holds that the festival memorializes the Chinese poet Qu Yuan of the Warring States Period. He committed suicide by drowning himself in a river because he was disgusted by the corruption of the Chu government. The local people， knowing him to be a good man， decided to throw food into the river to feed the fishes to prevent them from eating Qus body. They also sat on dragon boats， and tried to scare the fishes away by the thundering sound of drums aboard the boat and the fierce looking dragon-head in the front of the boat.

In the early years of the Chinese Republic， Duan Wu was also celebrated as "Poets Day"， due to Qu Yuans status as Chinas first poet of personal renown.

Today， people eat zongzi (the food originally intended to feed the fishes) and race dragon boats in memory of Qus dramatic death.
