环境污染的英语【合集20篇】

“保护环境，人人有责。”不少的垃圾桶上都有这样一句话。电视和广播等媒体也都倡议要保护环境。可总有些人把这些拒绝在外，还一如既往地随地扔垃圾。有的人也许曾经看到过：一条有很多垃圾桶的马路上，还是有被风吹起的塑料袋。

我见到过一个人，边骑车边吃早饭。早饭吃完，随手一扔，塑料袋就象鸽子一样飞了出去。还有小学生：她吃好桔子，佯装把橘子皮放进口袋，却不小心掉到地上，其实她是故意的。她放进口袋之际，用手拨到了地上，假装不知道它掉了出来。这样扔垃圾的事还不少，真想不出这样能得到什么好处。

世界上有不少地区已经被“白色污染”所笼罩。白色污染其实就是白色塑料袋不腐烂，而长期不去收集，所以塑料袋越积越多形成的污染。外国是靠燃烧塑料袋来发电，而我国是将它埋在地里，对沼气进行影响。所以塑料袋并不是一无是处，但是需要统一管理，使我国不被白色污染包围。

外国曾经有一只海鸥，从高空一下子坠落沙滩。一些关于保护动物的部分人员把海鸥肚子打开，发现海鸥肚子里全是瓶盖.塑料。因为水域被影响，无鱼可吃，就只好吃瓶盖了。看过污染带来的灾害，有些人会认为，没有殃及人，还是可以继续的。千万不要这样想。有些人还在大量毁坏森林，砍伐树木。有本书上写过：要是世界上没有了一草一木，人类只能再活五百天。

因为这样，所以我们要保护环境，拒绝污染。让世界成为环保的大家族!

Today, we read a lot about the passage to protect the environment. I recall ever happened in my side.

Remember last years summer vacation, my father and I went for a walk EHu edge, a way, Im kind of shouted thirsty, so my father on the side of the road store bought me a Popsicle. I ate and go, soon finished eating, carelessly threw the ice sticks into EHu. Dad saw, reminded me immediately; "Coco, cant litter oh! If everyone like you to throw garbage in the lake, the beautiful EHu lake becomes waste." Im ashamed of say: "know, next time I must not litter." Dad smiled and stroked my head and said: "the earth is our home, we should protect it, cherish it, let the sky bluer, the water cleaner, the grass is greener." I naughty to say: "oh, that is, everybody has said, the city is my home, clean environment depends on everybody. I understand." From then on, I no longer throw garbage.

I want to take care of the environment is closely related to everyone, so lets start from everyone!

今天，我们读了很多关于保护环境的小短文。我想起曾经在我身边发生的事情。

记得是去年的暑假，我和爸爸一起去鹅湖边散步，走了一段路，我就一个劲的喊口渴，于是，爸爸就在路边的小店给我买了根冰棍。我边吃边走，一会儿就吃完了，随手把冰棍棒往鹅湖里一扔。爸爸看见了，马上提醒我说;“可可，不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾，这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说：“知道了，我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说：“地球也是我们的家，我们应该保护它，爱护它，让天更蓝，水更清，草更绿。”我调皮的说：“噢，那就是大家一直说的，城市是我家，环境清洁靠大家。我明白了。”让从那以后，我再也不乱扔垃圾了。

我想爱护环境与每个人息息相关，所以要从每个人做起!

Chinahas a very long and brilliant history, whose people are so friendly

and hospitable. But I am wondering why some people pay such little attention to

the environment and nature. In many places of the countryside, rivers have

become stinking sewers and brooks have disappeared. Heaps of garbage obstructs

the scarce flow of dirty water. The grounds are littered with plastic bottles

and bags. People are cutting down trees even though it is illegal. In some

towns, rubbish is hidden behind walls. Garbage cans are often of little use,

making cleaners must rush all day long and also by night to clean the

rubbish.

This lack of consideration for nature in general is extremely detrimental

to children’s education, toChina’s image, to public health, to tourism and to

the future.Chinais the common treasure of all Chinese, and we should live up to

be a member of this big family, a descendant of 5000-year-plus ancient civilized

country. I think the environment must absolutely be strictly protected by all

means. This protection should go at the same pace as the marvelous development

of the nation.

In this respect,Germanyis a rare model and leaves me a very deep

impression. After you have an exciting tour around in this country for a week or

so, it is unnecessary for you to polish your leather shoes. Personally, first of

all, the strong awareness of people’s environmental protection; then, the

advanced technology applied in the field of preserving the nature; We can learn

form others in building China into one of the most environmentally friendly

places in the world.

电视里经常播放着湖州的迷人风光，古色古香的房屋,干净整洁的街道,风风火火的商店,事实是不是这样呢?

为了了解家乡环境，我对家乡的环境做了一下调查。调查的对象主要是工厂、河流、公共场所等。

一、空气污染

在我们的家乡，空气污染已十分严重。例如：工厂排放的烟尘废气，汽车、火车、轮船排放的烟尘废气，都含有许多对我们人体有害的物质，是空气的主要污染源。随着社会的进步，人们生活水平的不断提高，许多家庭中也有了各式的交通工具，如汽车、摩托车等，它们给我们的生活带来了方便，但是排出的废气却污染了我们周围的空气。

二、水污染

在我们家乡的小河，几乎全都受到了污染。家庭中的脏水，这些都会流进附近的小河，给我们的生活带来了影响。鱼类难以生存，其他生物的繁殖生长也受很大影响。比如奶奶家门前的小河吧!听爸爸说以前的小河，河水清澈见底，他们常去捉小鱼。而现在我来到了河附近，看到的却是另一番景象，河水的两边堆满了垃圾，甚至在河中也漂着一些白色垃圾。河水又黑又浊，哪里还有个小鱼的影子呢?而且河中还发出臭味。这哪里还是清澈见底的小河，简直是个“臭水沟”。

三、噪音污染。

家乡的噪音污染也十分的严重。噪音能影响人们的生活和工作，对听觉和身心健康都有损害，还会影响少年儿童智力发展，影响我们的思考和学习。噪音的主要来源是工厂、街道、建筑工地、公共场所等。在大街上，汽车、摩托车喇叭的声音，以上的三种污染，对我们的正常生活会有很大的影响，如果继续这样下去，还会威胁着我们的身体健康，以及造成其它方面的损失。

Although the world develops much faster and better, the resources on the earth get fewer and fewer. In order to protect them,something must be done.

尽管世界发展得更快，更好，地球上的资源越来越少。为了保护它们，必须做些什么。

Save water. Water is the source of life. No water, no life. So its very important for us to do so.Not only should we protect drinking water and stop polluting it, but also make full use of it.

节约用水。水是生命之源。没有水，就没有生命。所以，我们这样做是非常重要的。我们不仅要保护饮用水和停止污染，而且充分利用它。

Save electricity. It is crucial. We cant imagine what the life will be like without it. Everyone should do his best to save electricity. Dont forget to turn off lights or other electric machines when we finish working.

节约用电。这是至关重要的。我们无法想象的生活就会像没有它。每个人都应该尽自己的最大努力节约用电。不要忘记关灯或其他当我们完成工作的电机。

Save forests. They are useful .Please stop cutting them down and use recycled paper instead. Make our world a green one to live in.

拯救森林。他们是有用的。请停止切割下来，用再生纸代替。使我们的世界成为一个绿色的生活。

Recycle useful rubbish. Plenty of rubbish can be recycled like cans,paper, bottles, and so on. We can save resources in this way.

回收有用的垃圾。大量的垃圾可以回收罐一样，纸，瓶，等。我们以这种方式可以节省资源。

We all know it is becoming more and more important to protect our environment well.We should stop cutting down trees ,dropping litter everywhere and throwing waste before it is processed. It has caused lots of problems such as much rich land becomes desert;Rivers become dirty ;The air is becoming worse and worse ;The temperature is becoming hotter and hotter.So we must do something to change the situation.Wed better walk or ride bikes to work or go to school instead of driving a car,We mustnt use plastic bags.Our government must take some measures to prevent factories producing smoking etc.

henry ford didn’t always pay attention in school. one day ,he and a friend took a watch apart. angry and upset, the teacher told him both to stay after school. their punishment was to stay until they had fixed the watch. but the teacher did not know young ford’s genius. in ten minutes, this mechanical wizard had repaired the watch and was on this way home..

ford was always interested in how things worked. he once plugged up the spout of a teapot and placed it on the fire. then he waited to see what would happen. the water boiled and, of course, turned to steam. since the steam had no way to escape, the teapot exploded. the explosion cracked a mirror and broke a window. the young inventor was badly scalded

ford’s year of curiosity and tinkering paid off. he dreamed of a horseless carriage. when he built one, the world of transportation was changed forever.

air pollution comes from factories, power stations and cars. chemicals in the smoke from power stations cause a lot of damage. they can travel hundreds of miles in the wind before falling to the ground in the rain. but this "chemical rain" gradually destroys trees in the forests and kills fish in the lakes. in germany, over 50% of the country’s trees had been damaged by the year 1986.

time and time again there are serious accidents that pollute the air. in 1986 there was a bad accident at a nuclear power station in russia. a cloud of radiation crossed the whole of europe. it is said that 125,000 people died in russia as a result of illnesses caused by this accident.

in 1984 there was a serious accident at a factory in india and a cloud of dangerous gas covered the town of bhopal. over 2,500 people were killed that night, and hundreds of thousands of people were injured. many of the injured lost their sight.

The drawing portrays a tragic scene in which people are still polluting and leaving about the rubbish. Lots people show bad manners , entirely indifferent to the environment of the world we are living in.

The aim of the painter is assailing the serious environmental problem——pollution, for which several factors are responsible. Population as by far increased, our country is marked by the surpassing growth of economy; living standards are high up. But the environment leaves much to be regretted.

How miserable it is to live in such an environment! Who is to blame for the tragic？ Everybody should be responsible. we must prevent garbage from being thrown away into rivers, ponds, and lakes. With the water pollution going on someday we shall die with no water to drink at all. The scenery spots waiting to be re-beautified. Wild realization of what is our environment responsibility should be awakend. The must be exercises of our authority over the tourists to punish them sternly when they are found defiling our nature. Only in this way may can we cure the problems drastically, and regain perfect environment to live in.

这幅图画描绘了一幅悲惨的景象，人们仍在污染和留下垃圾。许多人表现不好的举止，对我们生活的世界环境漠不关心。

画家的目的犯了严重的环境问题——环境污染，所负责的几个因素。人口比我国的人口增长更为显著，我国的经济增长率明显超过了国民经济的增长，生活水平也很高。但是环境让许多遗憾。

生活在这样的环境中是多么的可悲！谁是谁的悲剧？每个人都应该负责。我们必须防止垃圾被扔进河里，池塘，湖泊。有一天我们会死，没有水喝的水污染。景点等待重新美化。我们的环境责任是什么野生的实现应该唤醒。必须锻炼我们的权力者的严厉惩罚他们，当他们发现玷污我们的本性。只有这样，我们才能彻底治愈这些问题，重新获得理想的生存环境。

[ 环境污染英语作文带翻译

污染环境是我们常见的事了。下面这篇就是围绕污染环境来写的。

我们村是一个工厂加工基地。有很多拉锯的。他的声音很让人烦。我的家就在一个工厂的后面，从前，工厂里特别脏，工人们这一天下来就成了土人，现在，科学了，老板把他们改造了，锯末通过管道抽到一个定点儿，但是他们还有一个换气的地方，是开着的。每到刮风或者锯末满的时候，被吹到四面地方，当我吸新鲜空气的时候，就能闻到一股味道，那就是锯末的味道，这时候你摸栏杆，就能看到锯末。那些锯末又脏又细的。而且跑到树上也很脏。要是飘得花里就不好办了。因为人们摸花的时候一不注意就会有细菌了。那这样也是很脏的。最主要的是，这时候我妈妈就不能晾衣服了，他们细小的尘土飞到衣服上，让人穿上是什么样的感觉。

从这件事我知道了锯末是多么有污染呀！

Now, people dont speak hygiene, make the earth became very clean.

Factory waste water into the river discharge, discharge waste water will not think about it, if people drink the water, what will happen?

Also, people cut down trees, on the lawn, people will think of these things, without the trees, how do we have the fresh air and oxygen, no grass we how green home! Besides, if sandstorm comes, without the trees blocking, what will become of our home.

Why are both street trash can, this is to remind people not to throw rubbish everywhere, put the rubbish in the garbage can. But, a lot of people love throwing garbage everywhere, this kind of behavior not only damage the image of our home, what also polluted the earth again.

I want to tell everyone: "protecting the environment is to love life!" To protect the environment, we should start from the side, starts from me, to build our homes more beautiful!

现在，人们都不讲卫生，使地球变得很不干净。

工厂里的废水向河里排，排废水的人会不会想想，如果人类喝了那些水，会怎么样?

还有，人们砍伐树木，踏入草坪，做过这些事的人会不会想想，没有了树木我们怎么有新鲜的空气和氧气，没有了小草我们怎么绿化家园啊!再说，如果沙尘暴来了，没有了树木的阻挡，我们的家园会变成什么样。

为什么街道旁都有垃圾桶，这是提醒人们不要随地乱扔垃圾，把手中的垃圾扔进垃圾桶里。但是，很多人都爱随地扔垃圾，这种行为不仅损坏我们家园的形象，还让地球再一次的被污染。

我想告诉大家：“保护环境就是爱护生命啊!”要想保护环境，就要从身边做起，从我做起，把我们家园建设得更加美丽吧!

From June1, 2008, shops and supermarkets are forbidden from offering free plastic bags to customers, according to a new law. A nation-wide campaign against plastic bags has been launched.

Nowadays, Chinese people use up to three billion plastic bags a day. While being very convenient to shoppers, plastic bags also cause serious white pollution” and waste resources.

Though the ban may cause some inconvenience to shoppers, it can help reduce the use of plastic bags when people have to pay for them. Besides, the ban, in away, can promote public awareness of environmental protection.

So I think it necessary to forbid shops and supermarkets from offering free plastic bags. When shopping, we can use cloth bags or baskets instead of plastic bags as we used to.

There are still many environmental protection problems in recent years. One of the most serious problems is the air, water and soil serious pollution. Air pollution seriously damage peoples health. Polluted water causes diseases and death. Whats more, vegetation has been greatly reduced, with the rapid growth of modern cities.

In order to protect the environment, governments in many countries have done a lot of work. This paper introduces the legislative measures to control air pollution, to protect forest resources and Marine resources, to stop any environmental pollution. Therefore, governments are play a most important function of the environmental protection today.

I think, in order to protect the environment, the government must take more concrete measures. First of all, the government should let people fully realize the importance of environmental protection, through education. Second, more efforts should be made to put the population planning policy, because more people means more people means more pollution. Finally, those who intentionally damage the environment should be punished severely. We should let them know that destroying environment means destroying mankind themselves.

仍然有很多环保问题在近几年。最严重的问题之一是空气，水和土壤的严重污染。污染的空气严重损害人们的健康。污染的水引起的疾病和死亡。更重要的是，植被已大大减少，随着现代城市的快速增长。

为了保护环境，许多国家的政府都做了很多工作。介绍了立法措施控制空气污染，保护森林资源和海洋资源，制止任何环境污染。因此，各国政府正在发挥环保今天最重要的作用。

我认为，为了保护环境，政府必须采取更具体的措施。首先，政府应该让人民充分认识到环境保护的重要性，通过教育。第二，更应努力把人口规划实施的政策，因为更多的人意味着更多的人意味着更多的污染。最后，那些故意破坏谁应该受到严厉惩罚的环境。我们应该让他们知道，破坏环境就是毁灭人类自己。

Environment is all the attention to the topic, also is a hot spot of all people. Good environment, good for our healthy growth, feel better, both study and life comfortable, everyone wants to live in a good environment. Therefore, to protect the environment, everyone duty.

When you are passing the trash can, you can pick up the cola bottles beside? When you see someone scribble carving in the tree, you will not to stop at the meeting? When you are in the stalls to eat small, can you come up with their own spare chopsticks instead of disposable chopsticks?

Now, a lot of people cut down a tree in the forest, the trees to make chopsticks, chairs, tables, etc., can cause soil erosion, flood will often and bring us unfortunately. We should act to prevent them.

In the supermarket, we can see a lot of people still use money to buy a pocket, although a pocket as long as 2 cents, but to protect the environment is every citizens responsibility and obligation. Even if the pockets dont money, we should also have the mindset of environmental protection, environmental protection bag.

On my way to school, we saw someone throw rubbish on the road, disorderly spit phlegm, we should teach him methods: spitting in the tissue, then throw in the trash. We cant learn the somebody else, be sure to write "environmental protection" moment in their heart, and reflect in action, starts from me, starts from the minor matter.

I believe that through the efforts of everyone, the environment will become better and better, "mother" will become more beautiful earth.

环境是目前所有人关注的话题，也是所有人关注的一个热点。好的环境，有利于我们健康成长、心情舒畅，无论学习和生活都特别舒服，所有人都希望生活在一个好的环境下。因此，保护环境，人人有责。

当你路过垃圾桶的时候，你会不会捡起旁边的可乐瓶?当你看见有人在树上乱刻乱画，你会不会上前去阻止?当你在小摊吃小面的时候，你会拿出自己的备用筷子而不用一次性筷子呢?

现在，很多人在森林里砍树，把树木做成筷子、椅子、桌子等等，就会造成水土流失，洪水也会经常冲来，带给我们不幸的危险。我们应该立刻行动，阻止他们。

在超市里，我们会看到很多人还用钱来买口袋，虽然一个口袋只要2角钱，但是保护环境是每一个公民的责任和义务。即使口袋不要钱，我们也应抱有保护环境的心态，用环保口袋。

在上学的路上，我们看见有人在路上乱扔垃圾，乱吐口痰，我们应该教给他方法：吐在纸巾里，然后扔进垃圾桶。我们更不能学人家，一定要把“保护环境”时刻记在心里，并体现在行动中，从我做起，从小事做起。

我相信，通过大家的努力，环境会变得越来越好，地球“妈妈”也会变得更加美丽。

放眼望去，眼前一片迷茫，不管是清晨，中午或傍晚，雾霾整天围绕着我们，属于我们的新鲜空气不知为何早已销声匿迹。

清晨，看着以前太阳升起时的方向，眼前只是灰蒙蒙的一片依稀看到太阳的轮廓，天空不在湛蓝属于我们的只是一片灰蒙蒙的雾霾，这到底是为何？随着工业的高速发展，设施的不完善都是造成环境污染的原因，但最主要的原因还是我们缺乏保护环境方面的知识。一些地区的工厂随便把污水在河流里排放，因此导致河水变成污水，鱼儿的家园变成鱼儿的噩梦。还有一些工厂为了利益不顾一切，私自排放污气和污水，使我们生活的环境和空气变得如此苦不堪言。污染环境给我们带来了不小的危害。第一，因空气污染人们的身体健康受到了威胁。是白血病，鼻癌，结肠癌，脑瘤的主要根源。听着这些字眼我不由害怕，这些字眼对于我们来说是晴天霹雳，是死亡的代词，是不治之症，可我们明明知道这些对我们人体有害为何不知悔改呢！第二，随着环境污染，被污染的地方将寸草不生，属于我们的绿洲我们将亲手摧毁。最后随着污气的排放，天空不再湛蓝属于我们的蓝天变成灰蒙蒙的一片，我们的生命安全将受到威胁。给我们带来日出行动不便。严重的地区五米外的物体看不清楚，车祸更是家常便饭了。

为了我们的身体健康，为了让社会多一个圆满的家庭，为了让世界有一个美好的明天，从现在开始《保护环境，人人有责》。

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 f 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.

Secondary school students as our primary task is to do a good job learning that is the protection of the environment on the basis of the knowledge you learn in their own minds, they can form a sense of environmental protection only do you have about your sense of action in order to have the idea then you have to do our best to influence People around to learn about the environment to understand the importance of environmental protection and you will make every effort to persuade friends and family and You fight side by side together to protect our common Earth

with the improvement of our living standard, more and more people can afford a car. as a result, our roads are more often than not crammed with cars. however, with more and more waste gas being discharged by the cars, the problem of air pollution becomes even more serious. so nowadays we advocate to lead a low-carbon life.

my suggestion is we should ride bikes more often instead of driving cars.by riding a bike, we can not only exercise our body but also protect our environment. why not have a try, my dear friends?

与我们的生活水平的提高,越来越多的人都买得起汽车的.因此,道路往往没有堆满了汽车.然而,随着越来越多的废气排放是汽车、空气污染问题变得更加严重.所以现在我们提倡过低碳的生活.

我的建议是我们应该更经常骑自行车而不是开车骑一辆自行车,我们不仅能锻炼身体,也能保护我们的环境.为什么不试试,我亲爱的朋友?

尊敬的市领导：

你们好!我是**小六年级二班的一名学生。

在这个美丽的城市里，我们快乐地成长着，幸福的生活着。以前，走在街道上，看到的是干干净净的马路，风儿吹过来，树叶发出“哗哗”的响声，那声音真悦耳，使人心情舒畅。大桥下是清澈见底的剑江河，犹如一面明亮的镜子。我喜欢以前的都匀城，因为它干净，漂亮，繁华，可爱。

可是近些年来，我们走在街道上，经常会看到被人们抛弃的白色垃圾，还有吃剩的香蕉皮、罐头，还有人们随地吐痰这些不文明的现象。人们一点也不珍惜清洁工的劳动成果。剑江河里的垃圾也逐渐多了起来。河面上漂浮着很多垃圾;有人们吃剩下的苹果核，还有人们喝饮料用的塑料杯，还有人们吃完烧烤后剩下的竹签......让人看起来感到很不舒服!

就这样，这个城市失去了昔日的辉煌与灿烂。

我们生活在这个城市，就有责任保护它。这个城市原本应该在人们的保护下变得更加美好，越发辉煌，可是为什么会变成这个样子呢?都是因为人们不保护环境而造成的。我认为人们应该保护环境，在此我建议人们做出以下改善：

(一)像塑料袋等可以重复利用的化学物品，不要把它扔在地上，更不要把它们埋在土里。

(二)不要乱扔垃圾。把垃圾归类放好后放在相应的垃圾箱里。

(三)变废为宝。在我们生活中有许多废电池，可以把废电池汇集起来，送到生产厂，重新加工。使电池能够再次为我们做出贡献。同时也保护了环境，珍惜了资源。

(四)多弯腰。当我们弯起腰捡地上的垃圾时，心里一种自豪的情感油然而生，多做了一件好事，保护了环境。

(五)珍惜资源。我国人口已经超过十三亿，由于人口的剧增，促使人们为了生存不断向大自然索取，为了满足自身的需求而破坏环境。我们应该多栽树木，不要乱砍伐树木，保护生态环境更是刻不容缓。

以上建议是我的片面之词，如有不恭，请谅解。但我仍要呼吁人们要保护环境：“人类啊，醒悟吧!保护环境就如同保护自己。让我们一起努力，共同创造更加美丽的明天!”

在我们的家乡,由于经济较为发达,几乎每家每户都拥有车子。汽车已经成为人们不可缺少的交通运输工具。它给我们们的生活和工作带来了极大的便利。但是，由于汽车数量的不断增多，汽车排放出来的尾气，也给地球妈妈带来了极大的危害。趁着周末，我们决定对“汽车尾气的危害”做一个调查。

通过上网查找资料，我们了解到汽车排出的废气中含有1000多种气体成分，其中对人体健康和环境危害最大的有一氧化碳、碳氢化合物、氮氧化物、二氧化碳等。一氧化碳是汽车排放废气中浓度最大的污染物，是无色、无味、无臭的窒息性气体。吸入过多一氧化碳会使人体缺氧，使中枢受损，引起功能性障碍，直至死亡。氮氧化物是各种含氮化合物的总称，汽车尾气中以一氧化氮居多，并有少量二氧化氮。氮氧化物的毒性很高，有强烈的刺激作用，会导致胸闷、咳嗽、气喘、肺炎乃至肺水肿。二氧化碳是大气主要的温室气体之一。排放过多，会使全球的气温升高，引起气候的不断恶化。

为了证实这一危害，我们把要做实验的意图跟家长说了，并征得了他们的支持。我们叫周旻晖爸爸发起车子，不要前进，原地不动。又拿出一盆开得正旺的菊花放在小板凳上，将小板凳拿到了汽车排气管后。一股股臭熏熏的黑烟从花瓣间飘过，一两分钟过去了，花儿还和原先的差不多；五分钟过去了，有几片花瓣已经凋谢了，十分钟后，那原先湿润的土壤都变得非常干燥，没有水分了。二十分钟后，那原先饱满、充满活力的茎都变得紧绷绷的，好像一根电线。通过这个试验我们明白了汽车尾气对植物的危害确实是很大的。

但是，为了进一步证明汽车尾气对动物有没有危害，我们又做了个实验。我们去王哲奶奶家的鸡窝里抓来了一只小鸡。那只小鸡一直望着我们，我们心想：为了证明汽车尾气排放对人类有哪些危害，已经牺牲了一盆花了。现在要拿这只可怜的小鸡做实验，真是有点于心不忍呢。但是为了寻找问题的答案，我们咬咬牙，还是决定坚持做下去。和上次差不多，我们先把小鸡用一个笼子关着，摆放在排气管后面，然后又叫叔叔将汽车发动。一股股黑烟又从排气管里冒出来了，一会儿功夫，小鸡的绒毛就被熏成灰色了。10分钟后，我们看到小鸡被熏得奄奄一息了。为了保住小鸡的性命，我们赶紧将它拿开，放在地上。看到小鸡跌跌撞撞的，我们心里一阵阵酸痛。我们对叔叔说，原来汽车的尾气对植物和动物的危害真的是这么大的呀。周旻晖爸爸语重心长的说：“任何事物都有两面性的。汽车作为人类进步的产物，它给人们带来了许多的便利，但同时也给人们带来了很多的危害啊。现在我们们国家也是很注重环境保护的，有很多城市都已经在开展‘无车日’活动了。”

是呀，为了我们这个赖以生存的地球，我们要争做环保小卫士，积极宣传汽车尾气对人类的危害，请爸爸妈妈们少开车，能步行的尽量步行，不仅环保，而且还可以锻炼身体，这样是不是一举两得呢？

Environmental problems are becoming more and more serious all over the world.With the development of industry and agriculture,cars make great noises and give off poisonous gas.Trees on the hills have been cut down,and waste water is being poured continuously into rivers.Furthermore,wherever we go today,we can find rubbish carelessly disposed.The whole ecological balance of the earth is changing.Massive destruction of environment has brought about negative effects and even poses a great threat to mans existence.

We must face the situation that exists and take actions to solve our environmental problems.For instance,new laws must be passed to place strict control over industrial pollution,the public must receive the education about the hazard of pollution and so on.We hope that all these measures will be effective and bring back a healthful environment.
