『貳』 關於綠色環保的英語演講稿

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?
與我們的生活水平的提高,越來越多的人都買得起汽車的。因此,道路往往沒有堆滿了汽車。然而,隨著越來越多的廢氣排放是汽車、空氣污染問題變得更加嚴重。所以現在我們提倡過低碳的生活。
我的建議是我們應該更經常騎自行車而不是開車騎一輛自行車,我們不僅能鍛煉身體,也能保護我們的環境。為什麼不試試,我親愛的朋友?

（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.

現在，我們身邊的汽車不斷的多了起來，環境也越來越糟糕！以至於我們周圍的空氣有很多有害物質。所以，我們要蘇身邊的小事做起。比如，我們可以騎自行車上學或者步行，這樣還可以鍛煉身體。有時間的話可以少用電梯，多爬樓梯。我們不僅能鍛煉身體,也能保護我們的環境。

（3）
文章文體：議論文。 文章要點：1.保護環境的重要性；2.學生在家庭中節約能源的具體做法和感想；3.今後的打算。 文章框架：文章應該是三部分兩段式。第一段（包括要點前兩部分）1.環保的重要性；2 接著是站在學生的角度談談家庭節約能源的具體方法，第二段寫第三要點，即談談今後打算。 重要句型短語：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。 參考例文： 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.

Recently we have held a class meeting to discuss what is considered to be honorable behavior and what is shameful. (最近我們班開了個班會討論什麼是光榮和恥辱。)It is really a pity to see all this in our school.(很遺憾在學校看到這些現象)Some students don』t respect their teachers or parents. (不尊敬老是和父母)Some don』t take their studies seriously and cheat in exams. (作業不認真，考試作弊)Some throw wastes everywhere and pollute the environment . (到處亂扔垃圾污染環境。)It is honorable to obey the law and rules , care much about our class and study hard.(關心班級、努力學習、遵紀守法是光榮)It is shameful to break school rules, to be selfish or to make little effort to achieve success.(違反學校紀律、自私 驕傲是可恥的)We should respect others and think more of them than of ourselves.(我們應該尊敬別人經常關心別人)We should work hard and make much more progress to repay the society.(我們應該努力學習取得更大進步從而回報社會。)We should try our best to keep the environment clean。(我們應該想方設法保持干凈的環境。)

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.
保護環境
目前環保還存在著許多問題。最嚴重的問題就是空氣、水和土壤的嚴重污染。污染的空氣對人類的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，隨著現代社會的迅速擴建，植被大大的減少。
為了保護環境，各國政府做了大量的工作。採用了立法措施控制大氣污染，保護森林資源和海洋資源，制止任何環境污染。因此，在當今的環保中政府起著最重要的作用。
我的看法是，為了保護環境，政府應當採取更具體的措施。首先，應當通過教育的方法使人們充分謒到環境保護的重要性。第二，應更加努力把計劃生育政策付諸實施，因為人口多就意味著污染嚴重。最後，要嚴懲那些故意破壞環境者。使他們破壞環境就是毀滅人類自己。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!望採納

『柒』 關於環境保護的英語演講稿

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 "
給你找了一個中英文對照的,能好理解些.

打好環保比賽、創建綠色北京

盡管2008北京奧運會離我們還有3年之遙，但有一項規模宏大的特殊比賽已經拉開了序幕。這場比賽的參加者並非來自世界各國的體育選手，而是身處北京的每一位公民，比賽的場所就是我們身邊的街區小巷。我想大家已經想到了我所說的這項特殊比賽，這就是"創建綠色北京、保護美好環境"。那麼在這場環保大賽中，我們究竟要與誰一比高低？是繁華現代的洛杉磯、風光迷人的悉尼、還是古老神奇的雅典？都不是！比賽的對手就是我們自己，就是我們自身淡漠的環保意識。
幾年前有幸在美國加州度過的一段時光，既讓我享受了那裡宜人的環境，更讓我領略了當地人民高度的環保意識。每當說到城市環保，我的眼前總會浮現出加州那蔚藍的天空、明媚的陽光、碧綠的草地以及嬉戲在樹枝間的松鼠、彩蝶和百靈鳥。
記得剛到美國時，常去爸爸工作的美國地質調查局玩耍，每次均能看到許多人騎自行車上下班，而其中一位滿頭白發的騎車老人，引起了我的好奇。我問爸爸，"那個爺爺為什麼總騎車上班，是不是沒錢買車？"爸爸笑道："沒錢買車？嘿，說出來嚇死你，他可是世界上頂級的大科學家。要論錢，他可以買一個車隊呢。" "那他咋不買車呢？騎車多累呀！" "他有車，但平時除非下雨或購物，一般不去開。在美國有許多人都是環保主義者，為了節約能源和減少汽車尾氣對大氣的污染，他們用實際行動倡導人們盡量少開車。而我們所居住的這座美國城市，還特別將每年的5月19日定成了'騎車上班日'，以支持和宣傳這種有效的環保行為。"
後來，我還在經常的搭車出行中獲知了他們的另一件環保趣事：在美國的許多州，政府為了鼓勵大家多坐公交車或幾人合用一輛車，以節省能源和緩解交通壓力，在城市內一些主幹道路上開辟有專門的'鑽石車道'，只有乘坐了二人或二人以上的車輛才從此通過。美國人民這種自覺的環保意識和政府有效的環保措施使我從內心對他們充滿了敬佩。並深刻地影響了我的環保理念。
回國後，常常有人問我："美國好嗎？"我總會脫口而出："確實好！最好的是環境。"說句真心話，回國三、四年，美國那邊同學和老師的面孔已經逐漸模糊，但加州那宜人的自然環境，卻每每清晰地浮現在我的眼前，成為我最深的記憶和期盼故地重遊的緣由，也成了我心目中北京環境的藍圖。2008奧運會為我們倡導和實施北京的環保提供了契機，北京能否有朝一日也擁有象加州那樣美麗的環境？答案是肯定的。但需要我們以真正的環保之心和切實的環保行動去一步一步地實現。
從現在開始，如果每一位有車的朋友一星期可以少開一、兩次車，每個讓家長用車接送的同學一周能主動讓家長少接送一兩趟而改乘公車或騎自行車，我們就會有擁有更多的藍天……。只要我們每一位北京市民都能夠自覺的從身邊的環保小事做起，加州的藍天、白雲和綠草地就會在北京安家，美國的松鼠、彩蝶和百靈鳥就會來北京落戶。
涓涓細流可以匯成滔滔江海，片片綠葉能夠造就莽莽森林。只要我們每一位北京市民都拿起手中的環保之筆，在我們所處的街頭巷尾，為北京這幅美麗而古老的畫卷添上自己的一抹綠色，就能使北京掩映在綠色的海洋中。讓我們一起行動起來，用我們集體的力量來打贏這場環保之賽，向全世界展現一塊最大的金牌，這就是"綠色北京、精彩奧運"。

『捌』 關於環保的英語演講稿（帶翻譯的）

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.
我們生活的世界變得越來越難以忍受,因為環境破壞的原因。例如,森林的破壞導致減少種植的土地和令人不快的天氣。此外,人類正面臨的問題和被污染的空氣污染的水。
很多已經採取措施。植樹有助於提高和美化環境。除此以外,環境保護法律已經實施,取得了良好的效果。
然而,問題的環保仍難以解決。另一方面,污染、破壞環境越來越糟在現代世界中。另一方面,缺乏知識的環境保護問題求解的制約。一言以蔽之,還有很長的路要走,我們享受了干凈、舒適的世界。

『玖』 綠色環保英語演講稿

英語綠色環保演講稿 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. 綠色奧運，綠色北京，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. 綠色北京 綠色奧運 你我同行 你可曾見到過動物哭泣？你可曾知道它們為什麼哭泣？正是因為我們不負責任的行為，讓世界變得骯臟，讓這些可愛的動物們哭泣不止。我們清楚的知道，如果沒有了動物和植物，我們的世界將會變得多麼死寂，多麼灰暗但是有些人仍然固執的犯著同樣的錯誤??破壞環境，執迷不悟！ 更糟糕的是，人們熱衷於品嘗野生動物。食用野生動物的人不知道，更不會想知道，正是這種行為導致了很多特殊問題的出現。例如：醫學家已經證實，舉世矚目的SARS疾病，正是由於食用野生動物傳播的。 如今，我們的世界已經不再整潔，不再美麗。為什麼呢？ 因為空氣，水和雜訊等污染已經變得越來越嚴重了。雜訊污染讓我們的脾氣變得極易暴躁；水污染讓河流和湖泊不再清澈，大氣污染讓天空變得不再蔚藍。環境污染，無處不在！ 無疑，清潔我們的環境勢在必行。然而可悲的是，許多人不能時刻領悟到保護環境的重要性。在街道上，你可以目睹汽車尾氣四處彌漫；在洗手間，你可以目睹有人用後卻不及時關閉水龍頭；甚至是在環境優美的公園，有人隨意的丟棄垃圾，但他們從來沒有意識到這種行為是錯的。 我們必須學會保護我們的環境。如果我們每個人都能伸出雙手，那麼我們的世界將會變得更整潔，更美麗，更和平。2008年奧運會的主題是"新北京，新奧運"，這也正是我們每個人的目標。 為了讓我們的家園充滿歡笑，我們必須立刻行動！從我做起，從今做起，從身邊小事做起。如果你還在隨意丟棄廢棄物；如果你還在公共設施上隨意刻畫；如果你還在公共場所隨地吐痰，那麼請你趕快改正！我們每個人都應該為改善環境做出努力，讓我們的家園變得像春天一樣美麗！ 2008年奧運會對我們來說，既是機遇，又是挑戰。我們衷心希望2008年的北京能夠，春風裁柳，碧如絲絛，紅日東升，光輝燦爛；夏雨過後，綠葉晶瑩，禾苗秀美，青松斜生；秋風習習，桂香飄飄，碧海藍天，秋水潺潺；冬梅傲骨，眾芳獨暄，白雪紛飛，覆壓枝頭。 讓我們沉醉於上蒼所給予的美景，流連忘返；讓我們迷戀於自然所散發的清香，沁人心脾。 讓我們以奧運為契機，呼喚環境意識，聚焦環境保護，弘揚綠色文明，分享綠色體驗！ 讓我們攜手，共建美好家園！ 綠色奧運，綠色北京，你我同行！ 第二篇自己修改一下就好了，加油，祝你好運！Good Luck！
