"One World One Dream" fully reflects the essence and the universal values of the Olympic spirit -- Unity, Friendship, Progress, Harmony, Participation and Dream. It expresses the common wishes of people all over the world, inspired by the Olympic ideals, to strive for a bright future of Mankind. In spite of the differences in colors, languages and races, we share the charm and joy of the Olympic Games, and together we seek for the ideal of Mankind for peace. We belong to the same world and we share the same aspirations and dreams. "One World One Dream" is a profound manifestation of the core concepts of the Beijing Olympic Games. It reflects the values of harmony connoted in the concept of "People's Olympics", the core and soul of the three concepts -- "Green Olympics, High-tech Olympics and People's Olympics". While "Harmony of Man with Nature" and "Peace Enjoys Priority" are the philosophies and ideals of the Chinese people since ancient times in their pursuit of the harmony between Man and Nature and the harmony among people, building up a harmonious society and achieving harmonious development are the dream and aspirations of ours. It is our belief that peace and progress, harmonious development, living in amity, cooperation and mutual benefit, and enjoying a happy life are the common ideals of the people throughout the world. "One World, One Dream" is simple in expressions, but profound in meaning. It is of China, and also of the world. It conveys the lofty ideal of the people in Beijing as well as in China to share the global community and civilization and to create a bright future hand in hand with the people from the rest of the world. It expresses the firm belief of a great nation, with a long history of 5,000 years and on its way towards modernization, that is committed to peaceful development, harmonious society and people's happiness. It voices the aspirations of 1.3 billion Chinese people to contribute to the establishment of a peaceful and bright world. The English translation of the slogan is distinctive in sentence structure. The two "One"s are perfectly used in parallel, and the words "World" and "Dream" form a good match. The slogan is simple, meaningful, inspiring, and easy to remember, read and spread. In Chinese, the word "tongyi", which means "the same", is used for the English word "One". It highlights the theme of "the whole Mankind lives in the same world and seeks for the same dream and ideal". “同一个世界 同一个梦想”（One World One Dream），集中体现了奥林匹克精神的实质和普遍价值观——团结、友谊、进步、和谐、参与和梦想，表达了全世界在奥林匹克精神的感召下，追求人类美好未来的共同愿望。尽管人类肤色不同、语言不同、种族不同，但我们共同分享奥林匹克的魅力与欢乐，共同追求着人类和平的理想，我们同属一个世界，我们拥有同样的希望和梦想。 “同一个世界 同一个梦想”（One World One Dream），深刻反映了北京奥运会的核心理念，体现了作为“绿色奥运、科技奥运、人文奥运”三大理念的核心和灵魂的人文奥运所蕴含的和谐的价值观。建设和谐社会、实现和谐发展是我们的梦想和追求。“天人合一”，“和为贵”是中国人民自古以来对人与自然，人与人和谐关系的理想与追求。我们相信，和平进步、和谐发展、和睦相处、合作共赢、和美生活是全世界的共同理想。 “同一个世界 同一个梦想”（One World One Dream），文简意深，既是中国的，也是世界的。口号表达了北京人民和中国人民与世界各国人民共有美好家园，同享文明成果，携手共创未来的崇高理想；表达了一个拥有五千年文明，正在大步走向现代化的伟大民族致力于和平发展，社会和谐，人民幸福的坚定信念；表达了13亿中国人民为建立一个和平而更美好的世界做出贡献的心声。 英文口号“One World One Dream”句法结构具有鲜明特色。两个“One”形成优美的排比，“World”和“Dream”前后呼应，整句口号简洁、响亮，寓意深远，既易记上口，又便于传播。 中文口号“同一个世界 同一个梦想”中将“One”用“同一”表达，使“全人类同属一个世界，全人类共同追求美好梦想”的主题更加突出。

奥巴马在上海与青年交流对话会演讲稿:Remarks by President Barack Obama at Town Hall Meeting with Future Chinese LeadersMuseum of Science and Technology, Shanghai, China1:18 P.M. CSTPRESIDENT OBAMA: Good afternoon. It is a great honor for me to be here in Shanghai, and to have this opportunity to speak with all of you. I'd like to thank Fudan University's President Yang for his hospitality and his gracious welcome. I'd also like to thank our outstanding Ambassador, Jon Huntsman, who exemplifies the deep ties and respect between our nations. I don't know what he said, but I hope it was good. (Laughter.)What I'd like to do is to make some opening comments, and then what I'm really looking forward to doing is taking questions, not only from students who are in the audience, but also we've received questions online, which will be asked by some of the students who are here in the audience, as well as by Ambassador Huntsman. And I am very sorry that my Chinese is not as good as your English, but I am looking forward to this chance to have a dialogue.This is my first time traveling to China, and I'm excited to see this majestic country. Here, in Shanghai, we see the growth that has caught the attention of the world -- the soaring skyscrapers, the bustling streets and entrepreneurial activity. And just as I'm impressed by these signs of China's journey to the 21st century, I'm eager to see those ancient places that speak to us from China's distant past. Tomorrow and the next day I hope to have a chance when I'm in Beijing to see the majesty of the Forbidden City and the wonder of the Great Wall. Truly, this is a nation that encompasses both a rich history and a belief in the promise of the future.The same can be said of the relationship between our two countries. Shanghai, of course, is a city that has great meaning in the history of the relationship between the United States and China. It was here, 37 years ago, that the Shanghai Communique opened the door to a new chapter of engagement between our governments and among our people. However, America's ties to this city -- and to this country -- stretch back further, to the earliest days of America's independence.In 1784, our founding father, George Washington, commissioned the Empress of China, a ship that set sail for these shores so that it could pursue trade with the Qing Dynasty. Washington wanted to see the ship carry the flag around the globe, and to forge new ties with nations like China. This is a common American impulse -- the desire to reach for new horizons, and to forge new partnerships that are mutually beneficial.Over the two centuries that have followed, the currents of history have steered the relationship between our countries in many directions. And even in the midst of tumultuous winds, our people had opportunities to forge deep and even dramatic ties. For instance, Americans will never forget the hospitality shown to our pilots who were shot down over your soil during World War II, and cared for by Chinese civilians who risked all that they had by doing so. And Chinese veterans of that war still warmly greet those American veterans who return to the sites where they fought to help liberate China from occupation.A different kind of connection was made nearly 40 years ago when the frost between our countries began to thaw through the simple game of table tennis. The very unlikely nature of this engagement contributed to its success -- because for all our differences, both our common humanity and our shared curiosity were revealed. As one American player described his visit to China -- "[The]people are just like us…The country is very similar to America, but still very different."Of course this small opening was followed by the achievement of the Shanghai Communique, and the eventual establishment of formal relations between the United States and China in 1979. And in three decades, just look at how far we have come.In 1979, trade between the United States and China stood at roughly $5 billion -- today it tops over $400 billion each year. The commerce affects our people's lives in so many ways. America imports from China many of the computer parts we use, the clothes we wear; and we export to China machinery that helps power your industry. This trade could create even more jobs on both sides of the Pacific, while allowing our people to enjoy a better quality of life. And as demand becomes more balanced, it can lead to even broader prosperity.In 1979, the political cooperation between the United States and China was rooted largely in our shared rivalry with the Soviet Union. Today, we have a positive, constructive and comprehensive relationship that opens the door to partnership on the key global issues of our time -- economic recovery and the development of clean energy; stopping the spread of nuclear weapons and the scourge of climate change; the promotion of peace and security in Asia and around the globe. All of these issues will be on the agenda tomorrow when I meet with President Hu.And in 1979, the connections among our people were limited. Today, we see the curiosity of those ping-pong players manifested in the ties that are being forged across many sectors. The second highest number of foreign students in the United States come from China, and we've seen a 50 percent increase in the study of Chinese among our own students. There are nearly 200 "friendship cities" drawing our communities together. American and Chinese scientists cooperate on new research and discovery. And of course, Yao Ming is just one signal of our shared love of basketball -- I'm only sorry that I won't be able to see a Shanghai Sharks game while I'm visiting.It is no coincidence that the relationship between our countries has accompanied a period of positive change. China has lifted hundreds of millions of people out of poverty -- an accomplishment unparalleled in human history -- while playing a larger role in global events. And the United States has seen our economy grow along with the standard of living enjoyed by our people, while bringing the Cold War to a successful conclusion.There is a Chinese proverb: "Consider the past, and you shall know the future." Surely, we have known setbacks and challenges over the last 30 years. Our relationship has not been without disagreement and difficulty. But the notion that we must be adversaries is not predestined -- not when we consider the past. Indeed, because of our cooperation, both the United States and China are more prosperous and more secure. We have seen what is possible when we build upon our mutual interests, and engage on the basis of mutual respect.And yet the success of that engagement depends upon understanding -- on sustaining an open dialogue, and learning about one another and from one another. For just as that American table tennis player pointed out -- we share much in common as human beings, but our countries are different in certain ways.I believe that each country must chart its own course. China is an ancient nation, with a deeply rooted culture. The United States, by comparison, is a young nation, whose culture is determined by the many different immigrants who have come to our shores, and by the founding documents that guide our democracy.Those documents put forward a simple vision of human affairs, and they enshrine several core principles -- that all men and women are created equal, and possess certain fundamental rights; that government should reflect the will of the people and respond to their wishes; that commerce should be open, information freely accessible; and that laws, and not simply men, should guarantee the administration of justice.Of course, the story of our nation is not without its difficult chapters. In many ways -- over many years -- we have struggled to advance the promise of these principles to all of our people, and to forge a more perfect union. We fought a very painful civil war, and freed a portion of our population from slavery. It took time for women to be extended the right to vote, workers to win the right to organize, and for immigrants from different corners of the globe to be fully embraced. Even after they were freed, African Americans persevered through conditions that were separate and not equal, before winning full and equal rights.None of this was easy. But we made progress because of our belief in those core principles, which have served as our compass through the darkest of storms. That is why Lincoln could stand up in the midst of civil war and declare it a struggle to see whether any nation, conceived in liberty, and "dedicated to the proposition that all men are created equal" could long endure. That is why Dr. Martin Luther King could stand on the steps of the Lincoln Memorial and ask that our nation live out the true meaning of its creed. That's why immigrants from China to Kenya could find a home on our shores; why opportunity is available to all who would work for it; and why someone like me, who less than 50 years ago would have had trouble voting in some parts of America, is now able to serve as its President.And that is why America will always speak out for these core principles around the world. We do not seek to impose any system of government on any other nation, but we also don't believe that the principles that we stand for are unique to our nation. These freedoms of expression_r_r_r_r_r_r and worship -- of access to information and political participation -- we believe are universal rights. They should be available to all people, including ethnic and religious minorities -- whether they are in the United States, China, or any nation. Indeed, it is that respect for universal rights that guides America's openness to other countries; our respect for different cultures; our commitment to international law; and our faith in the future.These are all things that you should know about America. I also know that we have much to learn about China. Looking around at this magnificent city -- and looking around this room -- I do believe that our nations hold something important in common, and that is a belief in the future. Neither the United States nor China is content to rest on our achievements. For while China is an ancient nation, you are also clearly looking ahead with confidence, ambition, and a commitment to see that tomorrow's generation can do better than today's.In addition to your growing economy, we admire China's extraordinary commitment to science and research -- a commitment borne out in everything from the infrastructure you build to the technology you use. China is now the world's largest Internet user -- which is why we were so pleased to include the Internet as a part of today's event. This country now has the world's largest mobile phone network, and it is investing in the new forms of energy that can both sustain growth and combat climate change -- and I'm looking forward to deepening the partnership between the United States and China in this critical area tomorrow. But above all, I see China's future in you -- young people whose talent and dedication and dreams will do so much to help shape the 21st century.I've said many times that I believe that our world is now fundamentally interconnected. The jobs we do, the prosperity we build, the environment we protect, the security that we seek -- all of these things are shared. And given that interconnection, power in the 21st century is no longer a zero-sum game; one country's success need not come at the expense of another. And that is why the United States insists we do not seek to contain China's rise. On the contrary, we welcome China as a strong and prosperous and successful member of the community of nations -- a China that draws on the rights, strengths, and creativity of individual Chinese like you.To return to the proverb -- consider the past. We know that more is to be gained when great powers cooperate than when they collide. That is a lesson that human beings have learned time and again, and that is the example of the history between our nations. And I believe strongly that cooperation must go beyond our government. It must be rooted in our people -- in the studies we share, the business that we do, the knowledge that we gain, and even in the sports that we play. And these bridges must be built by young men and women just like you and your counterparts in America.That's why I'm pleased to announce that the United States will dramatically expand the number of our students who study in China to 100,000. And these exchanges mark a clear commitment to build ties among our people, as surely as you will help determine the destiny of the 21st century. And I'm absolutely confident that America has no better ambassadors to offer than our young people. For they, just like you, are filled with talent and energy and optimism about the history that is yet to be written.So let this be the next step in the steady pursuit of cooperation that will serve our nations, and the world. And if there's one thing that we can take from today's dialogue, I hope that it is a commitment to continue this dialogue going forward.So thank you very much. And I look forward now to taking some questions from all of you. Thank you very much. (Applause.)So -- I just want to make sure this works. This is a tradition, by the way, that is very common in the United States at these town hall meetings. And what we're going to do is I will just -- if you are interested in asking a question, you can raise your hands. I will call on you. And then I will alternate between a question from the audience and an Internet question from one of the students who prepared the questions, as well as I think Ambassador Huntsman may have a question that we were able to obtain from the Web site of our embassy.下面的参考资料的链接便是“美国总统奥巴马在上海与中国青年对话”演讲视频

And what we're going to do is I will just -- if you are interested in asking a question, you can raise your hands. I will call on you. And then I will alternate between a question from the audience and an Internet question from one of the students who prepared the questions, as well as I think Ambassador Huntsman may have a question that we were able to obtain from the Web site of our embassy.So let me begin, though, by seeing -- and then what I'll do is I'll call on a boy and then a girl and then -- so we'll go back and forth, so that you know it's fair. All right? So I'll start with this young lady right in the front. Why don't we wait for this microphone so everyone can hear you. And what's your name?Q My name is (inaudible) and I am a student from Fudan University. Shanghai and Chicago have been sister cities since 1985, and these two cities have conduct a wide range of economic, political, and cultural exchanges. So what measures will you take to deepen this close relationship between cities of the United States and China? And Shanghai will hold the World Exposition next year. Will you bring your family to visit the Expo? Thank you.PRESIDENT OBAMA: Well, thank you very much for the question. I was just having lunch before I came here with the Mayor of Shanghai, and he told me that he has had an excellent relationship with the city of Chicago -- my home town -- that he's visited there twice. And I think it's wonderful to have these exchanges between cities.One of the things that I discussed with the Mayor is how both cities can learn from each other on strategies around clean energy, because one of the issues that ties China and America together is how, with an expanding population and a concern for climate change, that we're able to reduce our carbon footprint. And obviously in the United States and many developed countries, per capita, per individual, they are already using much more energy than each individual here in China. But as China grows and expands, it's going to be using more energy as well. So both countries have a great interest in finding new strategies.We talked about mass transit and the excellent rail lines that are being developed in Shanghai. I think we can learn in Chicago and the United States some of the fine work that's being done on high-speed rail. In the United States, I think we are learning how to develop buildings that use much less energy, that are much more energy-efficient. And I know that with Shanghai, as I traveled and I saw all the cranes and all the new buildings that are going up, it's very important for us to start incorporating these new technologies so that each building is energy-efficient when it comes to lighting, when it comes to heating. And so it's a terrific opportunity I think for us to learn from each other.I know this is going to be a major focus of the Shanghai World Expo, is the issue of clean energy, as I learned from the Mayor. And so I would love to attend. I'm not sure yet what my schedule is going to be, but I'm very pleased that we're going to have an excellent U.S. pavilion at the Expo, and I understand that we expect as many as 70 million visitors here. So it's going to be very crowded and it's going to be very exciting.Chicago has had two world expos in its history, and both of those expos ended up being tremendous boosts for the city. So I'm sure the same thing will happen here in Shanghai.Thank you. (Applause.)Why don't we get one of the questions from the Internet? And introduce yourself, in case --Q First shall I say it in Chinese, and then the English, okay?PRESIDENT OBAMA: Yes.Q I want to pose a question from the Internet. I want to thank you, Mr. President, for visiting China in your first year in office, and exchange views with us in China. I want to know what are you bringing to China, your visit to China this time, and what will you bring back to the United States? (Applause.)PRESIDENT OBAMA: The main purpose of my trip is to deepen my understanding of China and its vision for the future. I have had several meetings now with President Hu. We participated together in the G20 that was dealing with the economic financial crisis. We have had consultations about a wide range of issues. But I think it's very important for the United States to continually deepen its understanding of China, just as it's important for China to continually deepen its understanding of the United States.In terms of what I'd like to get out of this meeting, or this visit, in addition to having the wonderful opportunity to see the Forbidden City and the Great Wall, and to meet with all of you -- these are all highlights -- but in addition to that, the discussions that I intend to have with President Hu speak to the point that Ambassador Huntsman made earlier, which is there are very few global challenges that can be solved unless the United States and China agree. So let me give you a specific example, and that is the issue we were just discussing of climate change. The United States and China are the world's two largest emitters of greenhouse gases, of carbon that is causing the planet to warm. Now, the United States, as a highly developed country, as I said before, per capita, consumes much more energy and emits much more greenhouse gases for each individual than does China. On the other hand, China is growing at a much faster pace and it has a much larger population.
