汽车带来的环境污染英语作文【20篇】

The earth is the mother of mankind, the survival of mankind cannot leave her. Earth has taken a knock. How can we stand? He said my house on the west side of the river! Previously, the stream on the bottom, there are a lot of fish, shrimp swimming freely in it, all day live a carefree life, the river is full of vitality. At that time I like to play there. Now, because of the big cities site random discharge of sewage, and people are constantly littering. Disappeared, the vibrant river became a smelly sewage river, I dont like it!

Nowadays, many wild animals become a plate of food. Without these lovely animals, our life will become special boring. Rose up in the morning, cant hear the birds chirping and crisp sound, that is bad!

Patches of forest became less factories. The lawn into a wasteland, beautiful grassland into desert. Why is this? This is because people caused by deforestation.

地球是人类的母亲，人类的生存离不开她。地球受到了破坏，我们又怎么能袖手旁观呢?就说我家西边的小河吧!以前，这条小河清澈见底，有很多小鱼小虾在里面自由自在地游着，整天过着无忧无虑的生活，小河里充满了生机。那时我很喜欢到那里玩。现在，由于大城市的工地随意的排放污水，还有人们不断的乱扔垃圾。那条生机勃勃的小河不见了，变成了一条臭烘烘的污河，我再也不喜欢那里了!

如今，许多野生动物成为了人们盘中的美食。如果没有这些可爱的动物，我们的生活就会变得特别无趣。早晨起来，不能听到小鸟叽叽喳喳清脆的叫声，那多不好啊!

片片森林变成了座座工厂。草地变成了荒原，美丽的草原变成了沙漠。这究竟是为什么?这是因为人们乱砍乱伐造成的。

人类要靠环境生存，环境要靠人类保护。难道人类还要等到地球毁灭的那一刻才醒悟吗?我呼吁：保护环境!大家一起行动吧。

环境污染也使人类自食了苦果，让我们回顾一下历史，看看前人是怎样受到自然的惩罚的，这就是世界著名的八大公害事件

Over the past years, floods, droughts, landslides, and dust-storms have frequented our planet, the only habitat of human beings. Several days ago, tsunami(海啸) has swept the Southeast Asia, which has caused enormous damage. All these have sounded an alarm to human beings.

The destruction which is caused by human beings has aroused people’s concern all over the world. If we pay no heed to the present destructive human activities, our planet will become of tomb instead of cozy home. What’s more, we should realize that only from our planet can we obtain our sheltering, food, cloth and so forth.

Counter-measures must be taken to curb the destruction caused by human beings. Most importantly, laws must be established to punish those who are involved in destructive conducts.

here are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!

But how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live

我们家乡原来有一条清澈见底的小河，河底有许多五彩的鹅卵石，美丽极了，小鱼小虾在河里自由自在地玩耍。夏天到了，活泼的孩子们都来这里游泳、打水仗。冬天来了,河面上结了冰,孩子们又会来这里滑冰。

可是有一天，这幸福、美好的生活被打破了：河边建起了许多工厂，成天向河中排放污水、有毒的化学物质。于是，鱼虾离开了小河的怀抱，河底的鹅卵石被弄的肮脏不堪，小孩子们也不来这儿玩耍了。每当人们从这里经过时，就皱起眉头、捂住鼻子。河里的水把村里的庄稼都害死了。小河现在变得臭气熏天，鱼虾都不见了。孩子们也不再来这里玩耍了。

我建议大家保护自然环境，保护小河，保护我们的家园。

With the rapid development of science and technology, human demand for resources is increasing, causing the Antarctic arctic ice melting speed, rising sea levels, the Antarctic ozone hole, increasing dust storms in Beijing, haze weather, the Japanese earthquake nuclear pollution...

When we enjoy the good life at the same time, the thought of the importance of protecting the environment?

So, please keep an eye on our campus, look! The playground, school gate, stair aisle flying confetti, food bag, bottles; Look, those teeth bared on the white wall graffiti... These are not harmonious scene and our campus civilization!

The classmates, if we all take action, to be the master of environmental protection, do not throw confetti, peel, graffito of the scribble not, casually picked up confetti trash on the ground, take good care of the environment, our campus is dressed up beautifully and. When we walk on the tree-lined campus path, will feel relaxed and happy; When we study in bright classroom, will concentrate; When we study in the clean and elegant environment, will feel better.

Beautiful environment, let us know how to cherish, learn to cherish; Beautiful environment, let us knowledgeable and more civilized; Beautiful environment, let us learn to obey, learn to be a person; Beautiful environment, let our moral, make our learning more progress!

随着科技的高速发展，人类对资源的需求越来越多，致使南极北极冰雪融化的速度加快、海平面日渐上升、南极出现臭氧空洞、北京的沙尘暴、雾霾天气不断增加、日本大地震后造成的核泄漏污染……

当我们在享受美好生活的同时，是否想到保护环境的重要性呢?

那么，请同学们关注一下我们的校园，看!操场上、校门口、楼梯过道上漫天飞舞的纸屑、食品袋、饮料瓶;瞧，雪白的墙壁上那些张牙舞爪的涂鸦……这些都是和我们校园文明不和谐的一幕啊!

同学们，如果我们大家都行动起来，争当环保的主人翁，不乱扔纸屑、果皮，不乱涂乱画，随手捡起地上的纸屑垃圾，爱护环境，把我们的校园装扮的漂漂亮亮。当我们在绿树成荫的校园小道上漫步时，一定会感到心旷神怡;当我们在窗明几净的教室里读书时，一定会全神贯注;当我们在整洁优雅的环境中学习时，一定会心情舒畅。

优美的环境，让我们懂得珍惜，学会爱护;优美的环境，让我们知书达理，更加文明;优美的环境，让我们学会谦让，学会做人;优美的环境，让我们道德高尚，使我们的学习更加进步!

首先，我先给大家讲一个真实的事件。那是我随我的外公从宜昌坐船前往三峡时发生的一件事。

那天早晨，船上的人都起来了，正准备打水洗淑。可是船上的水龙头半天也只下来几滴水，一询问，原来是船上的水用完了！所以，大家只有排着长长的队伍，慢慢的等。我望着船下，船下虽然有着流不尽的江水，但却没有一个人愿意来使用它。因为江水太脏了，是那么的浑黄，又有谁敢去使用呢？只有慢慢的排队，慢慢的等！

如今科技虽然在高速发展，但这影响到了我们的环境。河流污染，大气污染，树木的减少，沙漠的增多……这一切的一切都是拜人类所赐！国家虽然在重视，世界虽然在重视，什么环境保护日，这些事又有多少人影起了注意呢？在我看来，是极少的。国家虽然在这么说，可是光说不做又有什么用呢？做了也只是少数罢了！根本没有从主要原因抓起！你看，黄河的水不是还在被污染吗？工厂不照样还在污染大气吗？抓，就应该从小抓起，从人们的素质，品质抓起，可是国家乃至世界这么做了吗？没有！即使做了也只是做样子罢了。环境不是照样还在被污染吗？

动物还在灭绝，山洪还在爆发，沙尘暴照样存在……这都充分说明了环境还在污染！国家只会去赈灾，而不去根本抓起，只会去赈灾，这又有什么用呢？各种灾难不还是照样在发生吗？我们应该像鲁迅一样。他当初从医是为了拯救中国人，而他发现，这解决不了根本，所以，他当了作家，去拯救人们的精神。因为这就是根本！所以，我们作为21世纪的小主人，就应该明白，什么是破坏环境的根本，从要点去解决它。努力吧――21世纪的我们

I am a child of the suns mother, my name is called the earth. I used to live happy, wake up in the morning, light rain "hua" to give me a bath; People planted many trees and flowers in my body, to get dolled up on me, then, clean running around the sun mother I, let the sun mother look at my new skirt. In the afternoon, the children from school, and I do homework together and play with me together. At night, people also make me very beautiful, they gave me the street lamp, make me golden... The mother said: "the human also is really good, not only your dress is very beautiful, also play with you, you are so blessed, so lucky!"

But now, the human is not as great as the sun mother said. They throw rubbish in my body, I got into a lot of dirty, human "car" still love discharge of tail gas, the rain is full of dirty water, the more I to wash the dirty; People still love the disorderly cut down trees flowers and plants, destruction of street lamp, make clothes and they gave me a bad bad, dirty... The sun mother urged me to say: "you still get rid of those humans!" But the good and I dont have the heart to leave them. Because it make me a bad meal every day, sleep well, so, I got sick, floods, earthquakes often... Some said 2012 could be the end of me. People in the disaster, are aware of this they destroy me, and they began to care about me, love me! I believe in the days that followed, I will become more beautiful, beautiful!

我是太阳妈妈的孩子，我的名字叫地球。我以前生活的很快乐：早上一醒来，小雨就“哗啦啦”地给我洗澡;人们在我身上种了很多花草树木，把我打扮得漂漂亮亮的，然后，干干净净的我就围着太阳妈妈转来转去，让太阳妈妈看看我的新裙子。下午，孩子们放学了，就和我一起写作业，一起和我玩。晚上，人们也把我打扮的很漂亮，他们给我身上安上路灯，把我打扮的金灿灿的……太阳妈妈说：“人类还真好，不仅把你打扮的很漂亮，还和你一起玩，你真是太有福气，太幸运了!”

可是现在，人类也不像太阳妈妈说的那么好了。他们在我身上乱扔垃圾，把我搞得浑身脏兮兮的，人类的“车”还爱排放尾气，雨下下来的全是脏水，把我越洗越脏;人们还爱乱砍伐树木花草，破坏路灯，把他们给我的衣服也搞得的烂烂的，脏脏的……太阳妈妈劝我说：“你还是摆脱那些人类吧!”可是好心的我又不忍心丢下他们。因为这件事让我每天吃不好饭，睡不好觉，所以，我就生病了，经常发洪水、地震……还有人说2012年可能是我的末日。人们在这些灾难中，意识到了这都是他们破坏我而造成的，于是他们又开始关心我，爱护我了!我相信以后的日子里，我一定会变得更加美丽、漂亮的!

国庆期间，我们班上的红领巾小队组织了一些为社区服务的集体活动，因为我没有接到小队成员的电话，所以没有参加活动，觉得真遗憾!但妈妈给我讲解了许多关于环保的知识，并带我在我们小区收捡垃圾，让我亲身体会白色污染的严重性。

妈妈告诉我：深圳到处可见快餐盒、塑料袋等垃圾，这些垃圾不仅影响城市的美观，更会危害人体的健康，这些白色垃圾对环境的破坏就是白色污染。 妈妈还告诉我：深圳是美丽的，但没有废弃物、没有白色污染的深圳会更美丽。

听了妈妈的这些话，我心里有些难过。心想：我们每一个人都应该从现在开始保护环境。

于是，我和妈妈把家中的旧报纸、旧课本、废纸片等集中起来，送往废品收购站。 然后我们把小区内的各种塑料袋、塑料泡沫、一次性塑料餐盒餐具捡起来扔进垃圾箱，把捡起来的易拉罐和矿泉水瓶也送往废品收购站， 妈妈说这些东西叫可回收垃圾。

通过妈妈与我的这次合作回收， 我觉得非常快乐和自豪，我会和同学们一起拒绝白色污染。

人类在生产生活的过程中，每天都要产生大量的废弃物、垃圾和排泄物。这些物质若果得不到有效处理，就排放出来，就会造成环境污染。

人们产生大量的废弃物、垃圾和排泄物进入大气，就会形成大气污染，尘埃降低能见度，影响生产，还会造成人类呼吸系统疾病;进入河流湖泊，就会造成水质恶化，破坏水生生态，影响工厂、城市、居民用水;进入土壤，破坏耕地，污染物还会通过植物生长积累毒性，最终影响人类健康。

环境污染弄脏了我们的大气和水，破坏了大地，损害了我们的健康。我们应该防止和治理环境污染。

Through the ages, the earth mother milk with sweet nurtured a countless generations. The original she was the XiaoBei decorated lovely. But, now human to its own interests, tortured her eyes out. There is only one earth; And the earth is facing serious environmental crisis. "Saving the earth" has become the worlds strongest voice. The deterioration of the environment around, I feel heartache, I think: as the future successors of teenagers, if dont understand the gravity of the environmental problems, ignoring the laws and regulations concerning environmental protection, not to strengthen environmental protection consciousness, our lives will be destroyed in his hands, and god will make serious punishment for us.

Therefore I determined to start from me good care environment, protect our homes, the survival of a environmental protection guard. In just the past year, I actively participate in school activities for planting trees, leading us six (2) squadron of the class cadre created the "green angel" plant green armor, encourage players green groups on campus adoption a young trees, use after school time for it to dress for its towering trees, grow and lay the foundation. In the school organization "let the earth vibrant" signature activity, I solemnly in signing their names above, and wrote his determination and expectations for environmental protection, the vision of the future. I actively participate in school in the world environment day, serious prize held consulting, collect got all kinds of material, to make social investigation, writing about environmental management idea articles, I often go to school organization environmental lecture, watch the footage of environmental protection, actively contributing to environmental protection knowledge interlocution survey, fill in every item questions.

I participated in the "red scarf plant green protect green team" website construction, in the above picture released a lot of environmental protection and environmental protection knowledge, as well as about environmental protection all aspects of legal knowledge in environmental protection in China, developing tendency, the situation of environmental protection in countries around the world; Every month I have used the Internet, newspapers, find some latest different projects and plate "environmental information" to tell everybody; Also making some XuanChuanBan regularly to promote environmental protection knowledge and life in environmental sense. Improve everyones environmental protection consciousness; Calls for students from different aspects to love his home, start from around things, and for the environment around dedicated an own strength!

I actively mobilize people around him come according to law, protect and construction human common is also the only home, in order to promote the sustainable development of economy and society for human civilization to make the contribution. I also jointly sponsored students and "raise a potted flower, adopted a tree, sparing the every piece of green space, let us surrounded by green" and "with a small plastic bags dont use foam lunch box and disposable chopsticks, let us from white pollution" initiative. Let us down convenience bag, took food basket, let us common to a wonderful green tomorrow, to glory, the bright future!

古往今来，地球妈妈用甘甜的乳汁哺育了无数代子孙。原来的她被小辈们装饰得楚楚动人。可是，现在人类为了自身的利益，将她折磨得天昏地暗。人类只有一个地球；而地球正面临着严峻的环境危机。“救救地球”已成为世界各国人民最强烈的呼声。

我为周围环境的恶化而感到心痛，我想：作为未来接班人的青少年，如果不了解环境问题的严重性，无视有关环境保护的法律法规，不去增强环境保护意识，我们的生命将毁在自己的手中，老天将对我们作出严厉的惩罚。为此我下定决心要从我做起爱护环境，保护我们这个赖以生存的家园，做一个保护环境的卫士。

在刚过去的一年中，我积极参加学校开展的植树活动，带领我们六（2）中队的班干部创立了“绿色天使”植绿护绿小组，鼓励队员们在校园里认养了一棵小树苗，利用课余时间给它梳妆打扮，为它长成参天大树打下了基础。在学校组织的“让地球充满生机”的签字活动中，我郑重地在上面签下自己的名字，并写下了自己对环保的决心和期望，对美好未来的憧憬。我积极参加学校在世界环境日举行的有奖征稿，认真查阅、收集各类资料，进行社会调查，撰写有关环境治理设想方面的文章，我经常去参加学校组织的环保讲座，观看环保方面的录相带，积极参预环保知识问答调查活动，认真填写每一项提问。我参与了“红领巾植绿护绿队”的网站建设，在上面发布大量的环保图片和环保知识，以及关于环保的各方面的法律知识，我国在环保方面发展动向、世界各国的环境保护情况；每个月我都利用网络、报纸，查找一些最新的不同的专题和板块“环保资讯”来告诉大家；还定期制作一些宣传板来宣传环保知识和生活中的环保常识。提高了大家的环保意识；号召同学们从不同的方面来关爱自己的家园，从身边的小事做起，为周围的环境奉献自己的一份力量!我积极动员身边的人一起来依法保护和建设人类共有的同样也是仅有的家园，为促进经济和社会的可持续发展，为人类的文明做出贡献。我还和同学们共同发起“养一盆花，认养一棵树、爱惜每一片绿地，让我们周围充满绿色”和“小用塑料袋不使用泡沫饭盒和一次性筷子，让我们远离白色污染”的倡议。让我们放下方便袋，拿起菜篮子，让我们共同走向美好的绿色的明天，走向辉煌、灿烂的未来!

我的家乡在朝阳，是一个非常美丽的城市，是世界上第一朵花绽放的地方，是世界上第一只鸟起飞的地方。有非常著名的东北佛教名山-凤凰山，还有蜿蜒曲折沿着城市流过的母亲河-大凌河，这里树木郁郁葱葱，天空湛蓝深远，空气清新甜润，景色非常优美。

近 几年，随着家乡经济的发展，很多企业来到家乡投资，家乡建起了很多的高楼大厦和工厂，但是也随之出现了一些污染问题。去年，我跟着妈妈的朋友一起参加了徒 步母亲河的活动，在徒步过程中，我看到好几个地方都有黑色的污水流进了大凌河，母亲河的被污染了，黑色的污水随着水流一直流向我们的城市。妈妈说，我们喝 的自来水就是取自大凌河，天哪，我们的水源被污染了，真着急啊。我们在路上还看到许多塑料袋，挂在树上非常的难看。

回家的路上，我跟妈妈 说，我一定要保护环境，妈妈问我，你觉得要怎么做呢？我想我要不乱扔果皮纸屑，不乱扔废旧电池，不使用一次性的塑料袋，还要向更多的人宣传保护环境的重要 性。妈妈指着湛蓝的天空说，这几年，朝阳市为环境发展做了很多事，在中国的很多城市，你是看不到这么蓝的天空的，但是我们今天也看到很多的工厂偷偷排放污 染物，城市的白色垃圾污染了我们的环境，破坏家乡的美丽景色，这就要我们每个人都有环保的意识，从一件件小事做起，让我们家乡的环境越来越好，我们的家乡越来越美。

Now, our living conditions more and more high, the environmental protection consciousness is more and more poor.

Everyone in the school pays much attention to health, the ground a piece of paper scraps, a piece of peel, a waste bottles are conveniently pick up, processing and classification, this much good!

But outside, everybody had changed. Lots of things to eat anywhere throw. By bus, eating snacks, threw it into bags. What paper bowl, beverage bottle, and the skin sunflower seeds, want to throw them. The bus drove past, leaving a scenery line of garbage.

Say again lets road along the river park. There was a tree-lined, charactizing a fine spring day. Today, so I can smell a strange smell. Approached a look, floating on the river some trash bags, convenient bowl, not many name of garbage, how the unchanged smelly! More let a person cant imagine that someone broke the river railing chain deliberately, how dangerous! The children walk also shake, more attention point.

Park is also a good place to go for a walk along the river, but Jiang Po edge is often the cattle eat grass there freely, defecate indiscriminately, attracted a lot of flies and bugs, disgusting. You walk tired, want to have a rest, but the road of four legs stone benches into three legs, stagger, garbage better stool, call a person how to sit?

Still another is not beautiful place, some ads posted everywhere, even on the telegraph poles, on the sidewalk with colorful paint brush an advertisers contact phone number, looking at is not pleasing to the eye. These are known as "city psoriasis" phenomenon, who for a treat!

Just turn a turn to the street, cant see too many beautiful place, this is the result of a people unconsciously. The Olympic Games is coming, if you still do not pay attention to the environment, will be foreign friends made fun of.

Protection of the environment depends on everybody, we must start from oneself, all hands to protect our homeland.

现在，我们的生活条件越来越高，可环境保护意识却越来越差了。

大家在学校里十分注意卫生，地面一片纸屑、一块果皮、一个废瓶罐都随手捡起，并分类处理，这多好啊!

可在校外，大家都变了个样。吃不完的东西随地乱扔。乘公交车时，一边吃零食，一边往外扔包装袋。什么纸碗啦、饮料瓶啦，还有果皮瓜子壳啊，想扔就扔。公交车开过，留下一道垃圾风景线。

再说说咱们的沿河路公园吧。那里本来绿树成荫，鸟语花香。如今，老远就闻到一股怪味。走近一看，河面上漂着一些垃圾袋、方便碗，还有许多叫不出名字的垃圾，河水怎么不变臭啊!更让人无法想象的是，有人把河边栏杆上的铁链故意弄断了，那多危险!小孩走路还摇、要多留心点。

沿江公园也是散步的好地方，可是江坡边常有牛儿自由地在那里吃草，随地大小便，引来许多的苍蝇和臭虫，真恶心。大家走累了，想休息一会儿，可路边四条腿的石条凳变成三条腿，东倒西歪的，好点儿的凳上有垃圾，叫人怎么坐啊?

还有个不美的地方，就是一些校广告到处贴，连电线杆上，人行道上都用五颜六色的油漆刷出广告人的联系电话，看着就不顺眼。这些被人们称作“城市牛皮癣”的现象，谁来治一治啊!

到街上随便转一转，就看到太多不美的地方，这都是大家不自觉造成的。奥运会就要来临了，要是大家还不注意环境，就要被外国朋友取笑了。

环境保护靠大家，我们一定要从自己做起，人人动手来保护我们的家园。

Since the winter last year,the smog has occurred a lot of times.it has done great harm to our daily life.many traffic accidents happened just because of the heavy smog weather,more and more people have to go to see the doctor because the serious disease caused by the smog,quite a lot of flights have to be put off,a great number of people have to stay at home for fear of the poisonous air caused by the smog.

People have realized the great harm caused by the smog and the importance of protecting the environment.people all over the country are taking measures to reduce the smog weather.the government suggests people go to work or school with the public traffic, such as the bus and the underground.Also we should plant more trees.

According to me, I will go to school by bike or on foot, and I won’t throw the waste anywhere.in addition, I will tell the people I meet to protect the environment as possible as they can.would you like to tell me some good ideas?i’m looking forward to your reply.

Yours,

Li Hua

I went to the gate of the primary school in shangjia city, and I was like walking into my other home, where I studied, lived, grew up, and my school was my home.

Lush trees, clean corridors, white walls. However, there are a few students on our campus who break the beautiful environment at will. The campus stairs and the various food packaging bags in the hallway, the various drink bottles of the flowers, the prunes in the classroom, the melon seed shells... The environment that makes us beautiful is destroyed, and it feels like a blank sheet of white paper. Taking care of the campus environment is the duty and responsibility of each of us.

So what can we do to make our campus environment civilized?

To set up the campus is the idea of home, the campus is my home, everyone loves it. Students should love the campus as much as they love their new clothes.

On the campus, the behavior should be standardized, from the little things, from a little bit, the daily behavior standard is every day, every time, everywhere.

We will comply with the regulations of the elementary school childrens daily behavior and strictly observe the institutions of the school. Be a good boy at home, be a good student at school, and be a civilized citizen in society.

4, do not break the environment of the school carelessly, should not throw waste to the ground; You shouldnt leave a mark or a handprint on a white wall. Consciously pick up every piece of paper or food bag on the floor; Stop unethical behavior.

To correct bad behavior, we cant just rely on our teachers and consciousness. Use concrete actions to protect and protect our campus environment. Start by myself, start by yourself, start every day, protect the campus environment.

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.

As time goes by,the importance of constructing a green campus is gradually executed in current society,not only for that the campus is the place which aimed at developing talents,but also for the campus is a symbol to a city.

The green campus not only refer to green environment,but also refer to a new idea about the ways of educating and managing the students,mainly letting them accept the knowledge and build up the

spirit of loving nature and being responsible for the environment,also,letting them take an active part in the actions of protecting the environment and keep the idea of sustainable development in mind.

In order to construct the green campus,we should do from two aspects.First of all,we should make every effort to study hard,aimed at becoming the knowledgeable ones with high qualities as well.Secondly,we should make ourselves more comprehensive,doing from the team-work spirit,the environmental consciousness and so on.Besides,we should be concerned about society,our motherland and the whole world,as well as learning to innovate and actively practice.

As is known to all, waste on campus has become a more and more serious problem. We can easily see many students dump a lot of food in the garbage can. Some students spend thousands of yuan buying fashionable clothes and so on.

The negative effects of waste can be shown in the following aspects. In the first place, it makes some students dependent on their parents for money, which is harmful to their development.

If they don’t learn to support themselves, they will be “useless people” when they graduate. In the second place, it is not easy for our parents to arrange for our schooling. Last but not the least important, there is no denying the fact that our country is still poor. There are many people who cannot go to university and many poor people still need our help.

As far as I am concerned, I should set a good example to reduce waste on campus. First of all, I will refrain from wasting anything, from food to stationery. What’s more, I’m determined to call on more schoolmates to fight against waste. Only through these measures can we hope to reduce waste on campus.

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。

One day after school, I carry bag cheerfully ran to the door.

Havent that take the door, can smell a stinking smell, turned out to be someone throw rubbish in the beside a little tree, I hurriedly will cover your nose, really want to breath ran to the third floor, left the flashpoint. But when I saw the red scarf before the bosom, it seemed to be in severe criticism I. I quickly ran home, the bag would not have time, picked up the broom and CuoJi to ran downstairs.

Ill use a broom and wielding a few times, this style was scared away a lot of flies, little fly, destroy the rubbish is much more relaxed, I put the rubbish swept into all CuoJi, in the trash.

I thought that has been accomplished, but, a few of wrappers are stuck on the ground, the part that the dense "" seems to be said to me:" ha ha, see what you can put me?" Had, water a blunt again and not line, I immediately end the basin of water, it worked, all dry I stamped out quietly, and finally restored the former days the ground clean.

Although the work of the accident was too tired to my waist sour backache, but think I for the earth environmental protection out of a force, let me very happy, as long as we care for the environment, the world will become more beautiful!

一天放学，我背着书包高高兴兴地向家门口跑去。

还没进门，就闻到一股臭气熏天的怪味，原来是有人把垃圾丢在了一颗小树旁，我赶紧将鼻子捂住，真想一口气跑到了三楼，离开了这个是非之地。可当我看到胸前的红领巾时，它仿佛在严厉的批评我。我急忙跑回家，书包也来不及放，拿起扫帚和撮箕向楼下跑去。

我先用扫帚使劲地挥舞几下，这招式果然吓走了不少苍蝇，少了苍蝇的捣蛋，消灭这些垃圾就轻松多了，我把垃圾全扫进撮箕里，倒入垃圾桶。

我以为已经大功告成了，可没想到，几张糖纸还粘在地上，这些“顽顾份子”似乎在对我说：“哈哈，看你能把我怎么办?”有了，用水一冲再扫不就行啦，我立马端了盆水，这招果然奏效，一下子全都被我消灭的干干静静，地面终于又恢复了往日的洁净。

虽然这次意外的劳动累得我腰酸背痛，但是想着我为地球环保出了一份力，让我十分高兴，只要我们大家爱护环境，世界一定会变得更加的美好!
