『贰』 关于绿色环保的英语演讲稿

We Only Have One World
As is known to all , we have a beautiful world .We can see the sun shining. We can see the moon in a full view. We can see the birds flying in the sky. We can see the horses running on the plain. However, the world is not as beautiul as before, for human beings have brought a disaster to the world.
So it is high time that we should do something to change this situation. As a citizen, we can do much for it. For example, we could use disposable goods less. And we are supposed to save resources such as water, electricity and so on. Also, we ought to plant more trees to rece the greenhouse effect. In addition, we could try our best to publicize the knowledge of environment protection. Because we only have one world.

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?

（2）
Now, our side of the car constant more up, the environment also increasingly worse! That the air around us there are many harmful substances. Therefore, we want to Sue around things start to do. For example, we can go to school by bike or walk, it can exercise. If you have time can use less elevator, many climb stairs. We can not only physical exercise, but also to protect our environment.

现在，我们身边的汽车不断的多了起来，环境也越来越糟糕！以至于我们周围的空气有很多有害物质。所以，我们要苏身边的小事做起。比如，我们可以骑自行车上学或者步行，这样还可以锻炼身体。有时间的话可以少用电梯，多爬楼梯。我们不仅能锻炼身体,也能保护我们的环境。

文章文体：议论文。 文章要点：1.保护环境的重要性；2.学生在家庭中节约能源的具体做法和感想；3.今后的打算。 文章框架：文章应该是三部分两段式。第一段（包括要点前两部分）1.环保的重要性；2 接着是站在学生的角度谈谈家庭节约能源的具体方法，第二段写第三要点，即谈谈今后打算。 重要句型短语：It is important to protect our environment, the energy in the world is limited. turn off the light and other appliance when you ,re not using them, we'd better not waste the energy, use public transportation, recycle the waste，I can learn more to develop new and clear energy, like the energy from the wind and solar 等。 参考例文： With the development of our society, energy in the world becomes more and more limited, so it is quite important for us to save energy and to protect our environment. As a student, there are a lot of methods we can do to save energy at home. For example, first, we can turn off the light as well as other appliances when we are not using them. Second, recycle the waste water, paper and other waste so that we can reuse them. What's more, it is suggested to use public transportation more instead of private cars. Above all, everyone can make a great contribution to our environment. I hope I can learn more to develop new and clear energy, like energy from the wind and solar.

There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reced with the rapid growth of modern cities.
To protect the environment, governments of many countries have done a lot. Legislative steps have been introced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through ecation. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.
保护环境
目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。
为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。
我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。Hello:
everyone!Now I want to talk about a beatiful world!
When I was young,I always dreamed that I lived in a beautiful country. There were many flowers and trees around our city.We counld hear the birds singing and see the children dancing. The streets were clear and the the air was very fresh! How nice it was!But that only was a dream of mine!How I wish that it would be come true! So I think we should do something to protect our environment. Everyone should make a contribution to protect the environment.
Taking care of our environment is very important.Where ever you live,you can do something around your neighbourhood.
Have you ever thrown any litter onto the ground?Have you ever drawn pictures on public walls? Have you ever cut down trees?If your answers are "No",it means that you have already helped protect our environment.
It is our ty to keep our envionment clean and tidy. You might ask yourself,"Have I ever picked up some rubbish and thrown it into a box?Have I ever collected waste paper or bottles for recycling?Have I ever planted any trees or flowers in or near my neighbourhood?"If your answers are"Yes",it means that you have already done something useful to improve the environment.
Now I want to say :Let`s do our best to make our world more beautiful!望采纳

『柒』 关于环境保护的英语演讲稿

Win Competition of Environment Protection for Beijing

Although the 2008 Olympics are still three years away, another special competition has already started in Beijing. This time, the competitors are not the athletes from all over the world, but the people living in Beijing. The special competition is not held in a stadium, but in every street and every corner of Beijing. I suppose some of you may have already guessed what the special competition is. Yes, it is the competition of protecting our environment and creating a green Beijing for the 2008 Olympic Games.

Someone may ask who is our rival in this competition? The modern Los Angeles, the charming Sydney, or the historic Athens? No, none of them. The real rival is ourselves. It is our bad habits of neglecting to protect environment in our daily life.

Several years ago, I was very lucky to have an opportunity to live in the United States for about two years. I not only enjoyed the beautiful environment there, but also appreciated the American people's active way of protecting their environment. Now, whenever the environment protection is mentioned, a beautiful view of California will arise in my mind: white clouds flying across the blue sky, green grassplot sprinkled with colorful flowers and small animals playing happily among the trees.

I remember that at the beginning of my coming to America, I often went to my father's working place, the United States Geological Survey, to have fun. Each time I found a lot of people riding bicycles to their offices. Among the cyclists, an old man with white hair attracted my attention. Curiously, I asked my father," Why does the old man ride his bike to work every day? Doesn't he have enough money to buy a car?" Father laughed, "No, not because of money. Actually, he is one of the greatest scientists in the world. He can afford to buy a motorcade if he likes. He is just an environmentalist and usually doesn't drive unless going shopping, or in bad weather. In America, there are a lot of environmentalists, who actively protect their environment. For example, in Palo Alto city we are living now, there is even a bicycle-to-work day on May 19th every year to encourage people to decrease air pollution caused by cars".

Later, I also learnt another interesting fact of environment protection there. In some states of America, in order to decrease air pollution, save energy and rece traffic jams, state governments encourage people to take buses to work or to share a car among several people. They even set special "diamond lanes" in some main streets, which are only for the vehicles with 2 or more people.

The positive actions of American people and the effective measures the American government takes in environment protection fully won my respects and deeply affected my consciousness in environment protection.

When I was back in China, people often asked me: " What do you think of America?" I always bolt out:" Wonderful, especially the beautiful environment." Frankly speaking, after several years, the faces of my American teachers and friends have graally faded away from my mind, but the blue sky, green grass and lovely animals in California often arise in my mind, and became my dream of visiting there again.

The 2008 Olympics provide us with the opportunity to publicize and practise environment protection in Beijing. Is it possible for Beijing to Is it possible for Beijing to become as beautiful as California? The answer is "yes", but the dream needs every Beijing citizen's full support and active moves to accomplish.

From now on, if every student who is driven to school can take bus or ride bicycle to school once a week, if every car owner goes to work in a car pool once a week, we can make a difference. If everyone can actively protect the environment in our daily life, the blue sky, green grass and lovely animals in California will appear in Beijing.

Tiny streams can combine into a vast ocean, small trees can together be an immense forest. Beijing is often described as a beautiful and aged picture. If every Beijing citizen adds a trait of green on the picture, the whole Beijing will become an ocean of green. Let us unite together to win the competition of environment protection in Beijing, and present the world a big gold medal. That is "Green Beijing, Great Olympics "
给你找了一个中英文对照的,能好理解些.

打好环保比赛、创建绿色北京

尽管2008北京奥运会离我们还有3年之遥，但有一项规模宏大的特殊比赛已经拉开了序幕。这场比赛的参加者并非来自世界各国的体育选手，而是身处北京的每一位公民，比赛的场所就是我们身边的街区小巷。我想大家已经想到了我所说的这项特殊比赛，这就是"创建绿色北京、保护美好环境"。那么在这场环保大赛中，我们究竟要与谁一比高低？是繁华现代的洛杉矶、风光迷人的悉尼、还是古老神奇的雅典？都不是！比赛的对手就是我们自己，就是我们自身淡漠的环保意识。
几年前有幸在美国加州度过的一段时光，既让我享受了那里宜人的环境，更让我领略了当地人民高度的环保意识。每当说到城市环保，我的眼前总会浮现出加州那蔚蓝的天空、明媚的阳光、碧绿的草地以及嬉戏在树枝间的松鼠、彩蝶和百灵鸟。
记得刚到美国时，常去爸爸工作的美国地质调查局玩耍，每次均能看到许多人骑自行车上下班，而其中一位满头白发的骑车老人，引起了我的好奇。我问爸爸，"那个爷爷为什么总骑车上班，是不是没钱买车？"爸爸笑道："没钱买车？嘿，说出来吓死你，他可是世界上顶级的大科学家。要论钱，他可以买一个车队呢。" "那他咋不买车呢？骑车多累呀！" "他有车，但平时除非下雨或购物，一般不去开。在美国有许多人都是环保主义者，为了节约能源和减少汽车尾气对大气的污染，他们用实际行动倡导人们尽量少开车。而我们所居住的这座美国城市，还特别将每年的5月19日定成了'骑车上班日'，以支持和宣传这种有效的环保行为。"
后来，我还在经常的搭车出行中获知了他们的另一件环保趣事：在美国的许多州，政府为了鼓励大家多坐公交车或几人合用一辆车，以节省能源和缓解交通压力，在城市内一些主干道路上开辟有专门的'钻石车道'，只有乘坐了二人或二人以上的车辆才从此通过。美国人民这种自觉的环保意识和政府有效的环保措施使我从内心对他们充满了敬佩。并深刻地影响了我的环保理念。
回国后，常常有人问我："美国好吗？"我总会脱口而出："确实好！最好的是环境。"说句真心话，回国三、四年，美国那边同学和老师的面孔已经逐渐模糊，但加州那宜人的自然环境，却每每清晰地浮现在我的眼前，成为我最深的记忆和期盼故地重游的缘由，也成了我心目中北京环境的蓝图。2008奥运会为我们倡导和实施北京的环保提供了契机，北京能否有朝一日也拥有象加州那样美丽的环境？答案是肯定的。但需要我们以真正的环保之心和切实的环保行动去一步一步地实现。
从现在开始，如果每一位有车的朋友一星期可以少开一、两次车，每个让家长用车接送的同学一周能主动让家长少接送一两趟而改乘公车或骑自行车，我们就会有拥有更多的蓝天……。只要我们每一位北京市民都能够自觉的从身边的环保小事做起，加州的蓝天、白云和绿草地就会在北京安家，美国的松鼠、彩蝶和百灵鸟就会来北京落户。
涓涓细流可以汇成滔滔江海，片片绿叶能够造就莽莽森林。只要我们每一位北京市民都拿起手中的环保之笔，在我们所处的街头巷尾，为北京这幅美丽而古老的画卷添上自己的一抹绿色，就能使北京掩映在绿色的海洋中。让我们一起行动起来，用我们集体的力量来打赢这场环保之赛，向全世界展现一块最大的金牌，这就是"绿色北京、精彩奥运"。

『捌』 关于环保的英语演讲稿（带翻译的）

The world we live in is becoming more and more intolerable because of environmental destruction. For example , forest destruction results in decrease of planting land and unpleasant weather. In addition, man is faced with problems of water pollution and air pollution.
A lot of measures have been taken. Planting trees helps improve and beautify the environment. Besides, laws concerning environmental protection have been put into effect and achieved good results.
However, the problem of environmental protection remains far from being solved. On the one hand, the environment pollution and destruction are getting worse and worse in the modern world. On the other hand, the lack of knowledge about the importance of protecting environment hinders the solving of the problem. In a word, there is a long way to go before we enjoy a clean and comfortable world.
我们生活的世界变得越来越难以忍受,因为环境破坏的原因。例如,森林的破坏导致减少种植的土地和令人不快的天气。此外,人类正面临的问题和被污染的空气污染的水。
很多已经采取措施。植树有助于提高和美化环境。除此以外,环境保护法律已经实施,取得了良好的效果。
然而,问题的环保仍难以解决。另一方面,污染、破坏环境越来越糟在现代世界中。另一方面,缺乏知识的环境保护问题求解的制约。一言以蔽之,还有很长的路要走,我们享受了干净、舒适的世界。

『玖』 绿色环保英语演讲稿

英语绿色环保演讲稿 Now more and more people are focusing on the nature. It is no doubt that the nature is important to every human being. No nature, no life. Because of the supplies of the nature, we have lived happily for a long time. And we started to gain every thing available from the nature. And this lasted so long a time. Today, people have discovered that the nature around is getting worse and worse. What is threatening the nature? Air and water pollution, overharvesting of plant and animal species, overpopulation and so on. Overpopulation is the biggest source of pollution. Let's take overpopulation as an example. What does overpopulation feel like? When we move slowly through the city in a tazi. When we enter a crowded slum district. When the temperature is high and when the air is thick with st and smoke. The streets are crowded with people. The streets seem alive with people. People eating. People washing. 绿色奥运，绿色北京，你我同行 Improving Beijing's environment for the Olympics Ladies and gentlemen: Good morning! Today, the title of my speech is Improving Beijing's environment for the Olympics. Have you ever seen animals cry? Do you know what makes them cry? It's the polluted world, a dirty world, caused by our irresponsible behaviors, that makes those lovely animals cry. Many of us are smart enough to know how terrible it is to have a world without animals and plants. But some people still persist in making the same errors and harming the environment. What's worse is that people are eating wild animals. Those people don't know, and more importantly, they don't want to know. This kind of behavior has caused some specific problems. For example, medical experts have suggested that eating wild animals helped spread the terrible disease SARS. Now, our world is no longer clean and beautiful. Why? Because air, water, and noise pollution has become more and more serious. Noise pollution makes us talk more loudly and become angry more easily. Water pollution makes our rivers and lakes very dirty. Air pollution is the most serious kind of pollution. Both air pollution and water pollution are not only dangerous to our health, but also dangerous to animals and plants. We're destroying our only world. A large number of trees have been cut down, so a lot of lands have been turned into deserts. Pollution can be seen everywhere! Unquestionably it is essential that we clean up our environment. Sadly, we've not always appreciated the importance of protecting the environment. On the streets, you can see cars procing smog. In the bathrooms, you can see students leaving the water tap on after using them. Not only the young people, but also the elderly ones throw things everywhere without thinking it's wrong, even in a beautiful park. these things are taking place every day, even in modern cities like Beijing. We can't do that any more. We must learn how to protect the environment. If everyone is aware of protecting it instead of destroying it, the world can become cleaner, more beautiful, and more peaceful. The theme of Beijing 2008 Olympic Games is "New Peking, New Olympic". It's the target owned by every Chinese. We should try our best to improve Beijing's environment for Olympics. , let's begin to act! First, start with the things around you. Don't throw rubbish onto the road. Don't talk loudly when you are outdoors. Turn off the water tap after using it. Go to school by bike or by bus instead of by private car. Save your pocket money and contribute to environmental protection organizations. Take me as an example, I take action in order to make our only world full of happiness. I pick up rubbish and throw it into a trashcan. I collect waste paper or bottles for recycling. I plant more trees and flowers, and so on. If you do all these things just like me, it means you have done something useful to improve the environment. We're grateful, because the emblem of the Beijing 2008 Olympic Games is a precious treasure dedicated to the Olympic Movement by the people of China. Under the guidance of the Olympic spirit, let us do a better job in all fields of our preparation and venue construction work in an efficient way. We will combine the Olympic Movement with the latest technology and advanced culture to make the Beijing Games the best Olympic Games ever! Welcome to Beijing! Thank you. 绿色北京 绿色奥运 你我同行 你可曾见到过动物哭泣？你可曾知道它们为什么哭泣？正是因为我们不负责任的行为，让世界变得肮脏，让这些可爱的动物们哭泣不止。我们清楚的知道，如果没有了动物和植物，我们的世界将会变得多么死寂，多么灰暗但是有些人仍然固执的犯着同样的错误??破坏环境，执迷不悟！ 更糟糕的是，人们热衷于品尝野生动物。食用野生动物的人不知道，更不会想知道，正是这种行为导致了很多特殊问题的出现。例如：医学家已经证实，举世瞩目的SARS疾病，正是由于食用野生动物传播的。 如今，我们的世界已经不再整洁，不再美丽。为什么呢？ 因为空气，水和噪声等污染已经变得越来越严重了。噪声污染让我们的脾气变得极易暴躁；水污染让河流和湖泊不再清澈，大气污染让天空变得不再蔚蓝。环境污染，无处不在！ 无疑，清洁我们的环境势在必行。然而可悲的是，许多人不能时刻领悟到保护环境的重要性。在街道上，你可以目睹汽车尾气四处弥漫；在洗手间，你可以目睹有人用后却不及时关闭水龙头；甚至是在环境优美的公园，有人随意的丢弃垃圾，但他们从来没有意识到这种行为是错的。 我们必须学会保护我们的环境。如果我们每个人都能伸出双手，那么我们的世界将会变得更整洁，更美丽，更和平。2008年奥运会的主题是"新北京，新奥运"，这也正是我们每个人的目标。 为了让我们的家园充满欢笑，我们必须立刻行动！从我做起，从今做起，从身边小事做起。如果你还在随意丢弃废弃物；如果你还在公共设施上随意刻画；如果你还在公共场所随地吐痰，那么请你赶快改正！我们每个人都应该为改善环境做出努力，让我们的家园变得像春天一样美丽！ 2008年奥运会对我们来说，既是机遇，又是挑战。我们衷心希望2008年的北京能够，春风裁柳，碧如丝绦，红日东升，光辉灿烂；夏雨过后，绿叶晶莹，禾苗秀美，青松斜生；秋风习习，桂香飘飘，碧海蓝天，秋水潺潺；冬梅傲骨，众芳独暄，白雪纷飞，覆压枝头。 让我们沉醉于上苍所给予的美景，流连忘返；让我们迷恋于自然所散发的清香，沁人心脾。 让我们以奥运为契机，呼唤环境意识，聚焦环境保护，弘扬绿色文明，分享绿色体验！ 让我们携手，共建美好家园！ 绿色奥运，绿色北京，你我同行！ 第二篇自己修改一下就好了，加油，祝你好运！Good Luck！
