Thank you, Miami Dade! Thank you. Please, everyone, be seated. 谢谢，迈阿密戴德！谢谢。请大家就座。
Hafeeza, thank you for that wonderful introduction. To Dr. Padron, Dr. Vicente, to the board of trustees, the faculty, parents, family, friends, and, most important, the class of 2011, congratulations -- congratulations on reaching this day. 哈菲扎，感谢你精彩的介绍。帕德龙博士、比森特博士、各位校董、教职员工、家长、朋友们，最重要的是，2011届的毕业生们，祝贺你们——祝贺你们迎来了这一天。
And thank you for allowing me the profound honor of being a part of it. And thank you for my first honorary associate degree. One of the perks of this job is that degrees come free these days. Not that it impresses anybody at home. Now Michelle just says, "Hey, Doctor, go take that dog for a walk." 感谢你们给予我莫大的荣誉，让我成为这一天的一部分。也感谢你们授予我的第一个荣誉副学士学位。这份工作的福利之一就是如今学位都是免费的。不过这在家里可没什么了不起。现在米歇尔只会说："嘿，博士，去遛狗吧。"
It is such a thrill to be at one of the largest, most diverse institutions of higher learning in America -- one that just this week was named one of the top community colleges in the nation. More than 170,000 students study across your eight campuses. You come from 181 countries, represented by the flags that just marched across this stage. You speak 94 languages. About 90 percent of you are minorities. And because more than 90 percent of you find a job in your field of study, it's fitting that your motto is "Opportunity changes everything." 能来到美国最大、最多元化的高等教育机构之一，我感到无比激动——就在本周，这里被评为全国顶尖社区大学之一。超过17万名学生在你们的八个校区学习。你们来自181个国家，刚才走过这个舞台的旗帜就代表着你们。你们使用94种语言。你们中大约90%是少数族裔。而且因为你们中超过90%的人在自己的专业领域找到了工作，你们的座右铭"机会改变一切"是再合适不过了。
As someone who's only here because of the chances my education gave me, I couldn't agree more. Opportunity changes everything. 作为一个仅仅因为教育赋予的机会才站在这里的人，我完全赞同。机会改变一切。
America will only be as strong in this new century as the opportunities that we provide you -- the opportunities that we provide to all our young people -- Latino, black, white, Asian, Native American, everybody. America will only be as strong as our pursuit of scientific research and our leadership in technology and innovation. 在这个新世纪，美国的强弱取决于我们为你们提供的机会——我们为所有年轻人提供的机会——拉丁裔、黑人、白人、亚裔、原住民，每一个人。美国的强弱取决于我们对科学研究的追求以及我们在技术和创新领域的领导力。
And I believe that community colleges like this one are critical pathways to the middle class that equip students with the skills and the education necessary to compete and win in this 21st-century economy. And that's why I've made community colleges a centerpiece of my education agenda, along with helping more students afford college. I couldn't be prouder of the work we've done in community colleges. And your accomplishment today is vital to America reclaiming the highest proportion of college graduates in the world by 2020. So I am proud of you. I am proud of you. 我相信像这样的社区大学是通往中产阶级的关键途径，它为学生提供了在21世纪经济中竞争和获胜所需的技能和教育。这就是为什么我将社区大学作为我教育议程的核心，同时帮助更多学生负担得起大学学费。我为我们所做的社区大学工作感到无比自豪。你们今天的成就对于美国到2020年重新夺回全球最高大学毕业生比例至关重要。所以我为你们感到骄傲。我为你们感到骄傲。
I know that for many of you reaching this day wasn't easy. 我知道对你们中的许多人来说，迎来这一天并不容易。
AUDIENCE: No. 观众：不容易。
THE PRESIDENT: See? I got some amens there. 总统：看到了吗？我得到了一些回应。
Perhaps you're the first in your family to go to college. Some of you have had to overcome big obstacles, defeat your own doubts, prove yourself to everyone who ever believed that you couldn't make it because of what you look like or where you came from. And, of course -- of course, for so many of you, this day represents the fulfillment of your family's dreams when you were born. This is their achievement as well, so give it up for your parents and your grandparents, your cousins and your uncles and your aunties. This is their day, too. This is their day, too. 也许你是家里第一个上大学的人。你们中的一些人不得不克服巨大的障碍，战胜自己的疑虑，向每一个因为你的外貌或出身而认为你不行的人证明自己。当然——当然，对你们中的许多人来说，这一天代表着你们出生时家庭梦想的实现。这也是他们的成就，所以为你们的父母、祖父母、表亲、叔叔和阿姨们鼓掌吧。这也是他们的日子。这也是他们的日子。
See, the diploma you're about to receive stands for something more than the investment you made in yourselves. It's the result of an investment made by generations before you; an investment in that radical yet simple idea that America is a place -- the place -- where you can make it if you try. That's the ideal that has made this country -- that's the idea that's represented by that one flag that all of you cheered for; that's what has made us a shining light to the world. 看，你们即将获得的文凭代表着比你们对自己的投资更重要的东西。它是前几代人投资的结果；投资于那个激进而简单的理念——美国是一个地方——那个地方——只要你努力就能成功。这就是造就这个国家的理想——这就是那面你们为之欢呼的旗帜所代表的理念；这就是让我们成为世界灯塔的原因。
And preserving this idea -- keeping the American Dream alive from one generation to the next -- that's never been an easy task. It's an even greater test in times of rapid change. 维护这个理念——让美国梦代代相传——从来都不是一件容易的事。在快速变革的时代，这是一个更大的考验。
And all of you are graduating at a moment when change is coming faster than ever before. We're emerging from an economic downturn like we haven't seen since the 1930s. Massive shifts in technology have shifted profoundly what our economy looks like. Massive shifts abroad geopolitically have swift and dramatic impacts not only overseas but also here at home, from markets on Wall Street to wallets on Main Street. 你们都在一个变革比以往任何时候都来得更快的时刻毕业。我们正从一场自20世纪30年代以来前所未见的经济衰退中复苏。技术的巨大变革深刻地改变了我们的经济面貌。海外地缘政治的巨大变化不仅在国外，而且在国内也产生了迅速而戏剧性的影响，从华尔街的市场到普通人的钱包。
Just as advances in technology have the power to make our lives better, they also force us to compete with other nations like never before. Tackling big challenges like terrorism and climate change require sustained national effort, and yet too often, our politics seems as broken, as divided as ever. 正如技术进步有能力改善我们的生活，它们也迫使我们以前所未有的方式与其他国家竞争。应对恐怖主义和气候变化等重大挑战需要持续的国家努力，然而我们的政治常常看起来和以往一样破碎，一样分裂。
So I know that for many of you it's an intimidating time to be marching out into the world. Everything seems so unsettled. The future may seem unclear. But as you make your way in this ever changing world, you should take comfort in knowing that as a country, we've navigated tougher times before. We've sailed stormier seas. 所以我知道对你们中的许多人来说，踏出校门走向世界是一个令人生畏的时刻。一切看起来都不确定。未来看起来不明朗。但当你们在这个不断变化的世界中前行时，你们应该感到安慰，因为作为一个国家，我们以前经历过更艰难的时期。我们航行过更汹涌的大海。
Earlier today, I spent some time in Tuscaloosa, Alabama. And some of you have seen what happened there as a consequence of the tornadoes that struck. The mayor and I visited a community where the devastation from this storm was simply heartbreaking -- entire homes and blocks just gone, wiped away. Some families lost everything. Some families lost family. 今天早些时候，我在阿拉巴马州的塔斯卡卢萨度过了一段时间。你们中的一些人看到了龙卷风袭击后发生的事情。市长和我访问了一个社区，这场风暴造成的破坏简直令人心碎——整个房屋和街区都不见了，被夷为平地。一些家庭失去了一切。一些家庭失去了亲人。
But what was striking is the way that damaged community has come together, how they've rallied around one another. The mayor there, young man doing wonderful work, Mayor Maddox, he put it best. He told me that when disasters like this strike, all our grievances seem to go away. All our differences don't seem to matter. All our political disagreements seem so petty. We help each other, we support one another, as one country, as one people. 但令人震撼的是，那个受灾社区是如何团结在一起的，他们是如何互相支持的。那里的市长，一个做着出色工作的年轻人，马多克斯市长，他说得最好。他告诉我，当这样的灾难来袭时，我们所有的怨恨似乎都消失了。我们所有的分歧似乎都不重要了。我们所有的政治分歧似乎都变得微不足道。我们互相帮助，互相支持，作为一个国家，作为一个民族。
That's the American spirit. No matter how hard we are tested, we look to our faith and our faith in one another. No matter what the challenge, we've always carried the American Dream forward. That's been true throughout our history. 这就是美国精神。无论我们受到多大的考验，我们都依靠信仰和对彼此的信仰。无论面对什么挑战，我们总是将美国梦推向前进。这在我们整个历史中都是如此。
When bombs fell on Pearl Harbor, when an Iron Curtain fell over Europe, when the threat of nuclear war loomed just 90 miles from this city, when a brilliant September morning was darkened by terror -- in none of those instances did we falter. We endured. We carried the dream forward. 当炸弹落在珍珠港，当铁幕降落在欧洲，当核战争的威胁就在这座城市90英里之外，当一个灿烂的9月清晨被恐怖笼罩——在这些时刻，我们都没有退缩。我们坚持了下来。我们将梦想推向前进。
We've gone through periods of great economic turmoil, from an economy where most people worked on farms to one where most people worked in factories to now one fueled by information and technology. Through it all, we've persevered. We've adapted. We've prospered. 我们经历了巨大的经济动荡时期，从一个大多数人在农场工作的经济体，到一个大多数人在工厂工作的经济体，再到一个由信息和技术驱动的经济体。在这一切中，我们坚持不懈。我们适应了。我们繁荣了。
Workers found their voice, and the right to organize for fair wages and safe working conditions. We carried forward. 工人们找到了自己的声音，获得了为公平工资和安全工作条件而组织的权利。我们继续前进。
When waves of Irish and Italian immigrants were derided as criminals and outcasts; when Catholics were discriminated against, or Jews had to succumb to quotas, or Muslims were blamed for society's ills; when blacks were treated as second-class citizens and marriages like my own parents' were illegal in much of the country -- we didn't stop. We didn't accept inequality. We fought. We overcame. We carried the dream forward. 当爱尔兰和意大利移民浪潮被嘲笑为罪犯和弃儿；当天主教徒受到歧视，犹太人不得不屈服于配额，穆斯林被指责为社会弊病的根源；当黑人被视为二等公民，像我父母这样的婚姻在全国大部分地区都是非法的——我们没有停止。我们没有接受不平等。我们战斗了。我们克服了。我们将梦想推向前进。
We have carried this dream forward through times when our politics seemed broken. This is not the first time where it looked like politicians were going crazy. 在我们的政治看起来已经破碎的时代，我们也一直将这个梦想推向前进。这不是政客们看起来发疯的第一次。
In heated debates over our founding, some warned independence would doom America to "a scene of bloody discord and desolation for ages." That was the warning about independence. One of our greatest Presidents, Thomas Jefferson, was labeled an "infidel" and a "howling atheist" with "fangs." Think about that. Even I haven't gotten that one yet. 在关于我们建国的激烈辩论中，有人警告独立将使美国陷入"长达数代的血腥冲突和毁灭的场景"。这就是对独立的警告。我们最伟大的总统之一，托马斯·杰斐逊，被贴上了"异教徒"和"嚎叫的无神论者"的标签，说他有"尖牙"。想想看吧。连我都没被这样说过。
Lincoln -- Lincoln, FDR, they were both vilified in their own times as tyrants, power hungry, bent on destroying democracy. And of course, this state has seen its fair share of tightly contested elections. 林肯——林肯、富兰克林·德拉诺·罗斯福，他们在各自的时代都被诋毁为暴君、权力饥渴者、蓄意破坏民主的人。当然，这个州也经历了许多势均力敌的选举。
And we've made it through those moments. None of it was easy. A lot of it was messy. Sometimes there was violence. Sometimes it took years, even decades, for us to find our way through. But here's the thing. We made it through. We made it through because in each of those moments, we made a choice. 我们已经度过了那些时刻。没有一件事是容易的。很多事情都是混乱的。有时还有暴力。有时我们花了几年甚至几十年才找到出路。但关键是，我们走过来了。我们走过来了，因为在每一个那样的时刻，我们都做出了选择。
Rather than turn inward and wall off America from the rest of the world, we've chosen to stand up forcefully for the ideals and the rights we believe are universal for all men and women. 我们没有向内收缩，将美国与世界隔绝，而是选择坚定地为我们认为对所有男女普遍适用的理想和权利而战。
Rather than settle for an America where everybody is left to fend for themselves, where we think only about our own short-term needs instead of the country that we're leaving to our children, we have chosen to build a nation where everybody has a shot at opportunity, where everyone can succeed. 我们没有满足于一个人人都只能自谋生路的美国，在那里我们只考虑自己的短期需求，而不是我们留给子孙后代的国家，我们选择建设一个人人都有机会、人人都能成功的国家。
We've chosen to invest in our people and in their future -- building public schools, sending a generation to college on the GI Bill, laying highways and railroads, building ports all across the country. 我们选择投资于我们的人民和他们的未来——建设公立学校，通过退伍军人法案送一代人上大学，铺设公路和铁路，在全国各地建设港口。
Rather than turn on each other in times of cultural upheaval, we've chosen to march, to organize, to sit-in, to turn out, to petition our government for women's rights and voting rights and civil rights -- even in the face of fierce resistance -- because we are Americans; and no matter who we are or what we look like, we believe that in this country, all are equal, all are free. 我们没有在文化动荡时期互相攻击，而是选择游行、组织、静坐、动员、向政府请愿，争取妇女权利、投票权和公民权利——即使面对强烈的抵抗——因为我们是美国人；无论我们是谁，无论我们长什么样，我们相信在这个国家，所有人都是平等的，所有人都是自由的。
Rather than give in to the voices suggesting we set our sights lower, downsize our dreams, or settle for something less, we've chosen again and again to make America bigger, bolder, more diverse, more generous, more hopeful. 我们没有屈服于那些建议我们降低目标、缩小梦想或安于现状的声音，我们一次又一次地选择让美国变得更大、更勇敢、更多元、更慷慨、更有希望。
Because throughout our history, what has distinguished us from all other nations is not just our wealth, it's not just our power. 因为在我们的整个历史中，使我们区别于所有其他国家的不仅仅是我们的财富，不仅仅是我们的力量。
It's been our deep commitment to individual freedom and personal responsibility, but also our unshakeable commitment to one another -- a recognition that we share a future; that we rise or fall together; that we are part of a common enterprise that is greater, somehow, than the sum of its parts. 而是我们对个人自由和个人责任的深刻承诺，以及我们对彼此不可动摇的承诺——认识到我们共享一个未来；我们同甘共苦；我们是某种比各部分总和更伟大的共同事业的一部分。
So, yes, class of 2011, change will be a constant in your lives. And that can be scary. That can be hard. 所以，是的，2011届的毕业生们，变化将是你们生活中的常态。这可能令人恐惧。这可能很困难。
And sometimes you'll be tempted to turn inward; to say "What's good enough for me is good enough." Sometimes you'll be tempted to turn on one another; to say "My problems are the fault of those who don't look like me or sound like me." Sometime you'll be tempted to give into those voices that warn: "too hard," "don't try," "no, you can't." 有时你们会受到诱惑，向内收缩；说"对我够好的就够了。"有时你们会受到诱惑，互相攻击；说"我的问题都是那些看起来或听起来不像我的人的错。"有时你们会屈服于那些警告"太难了"、"别试"、"不，你不行"的声音。
But I have faith you will reject those voices. I have faith you will reject those impulses. Your generation was born into a world with fewer walls; a world educated in an era of information, tempered by war and economic turmoil. 但我相信你们会拒绝那些声音。我相信你们会拒绝那些冲动。你们这一代人出生在一个墙壁更少的世界；一个在信息时代受教育、经受战争和经济动荡考验的世界。
And as our globe has grown smaller and more connected, you've shed the heavy weights of earlier generations. Your generation has grown up more accepting and tolerant of people for who they are, regardless of race or gender or religious belief; regardless of creed or sexual orientation. That's how you've grown up. You see our diversity as a strength, not a weakness. 随着我们的地球变得更小、更紧密相连，你们已经摆脱了前几代人的沉重负担。你们这一代人在成长过程中对人们的接纳和包容程度更高，无论他们的种族、性别或宗教信仰如何；无论信条或性取向如何。这就是你们的成长方式。你们将我们的多样性视为力量，而非弱点。
And I believe those life experiences have fortified you, as earlier generations were fortified, to meet the tests of our time. Everything I have seen of your generation has shown me that you believe, as deeply as any previous generation, that America can always change for the better. 我相信这些生活经历已经使你们坚强起来，就像前几代人一样，能够应对我们这个时代的考验。我所看到的关于你们这一代人的一切都向我表明，你们和任何前几代人一样深信，美国总是可以变得更好。
Class of 2011, you and your generation are now responsible for our future. I'm only going to be President a little bit longer. You are going to be leaders for many years to come. You will have to make choices to keep our dream alive for the next generation. 2011届的毕业生们，你们和你们这一代人现在对我们的未来负责。我只会在总统职位上再待很短一段时间。你们将在未来许多年里成为领导者。你们必须做出选择，为下一代保持我们的梦想。
Choices about whether we'll stack the deck against workers and the middle class, or whether we make sure America remains a place where if you work hard you can get ahead. You're going to have to make a choice about whether we'll say we can't afford to educate our young people and send them to college, or whether we continue to be a country that makes investments that are necessary to keep those young people competitive in this new century. 关于我们是打压工人和中产阶级，还是确保美国仍然是一个只要你努力工作就能取得进步的地方。你们必须做出选择，关于我们是说我们负担不起教育年轻人并送他们上大学，还是继续成为一个做出必要投资以保持这些年轻人在新世纪竞争力的国家。
It will be up to you to choose whether we'll remain vulnerable to swings in oil prices or whether we invest in the clean energy that can break our dependence on oil and protect our planet. It will be your choice as to whether we break our promise to seniors and the poor and the disabled and tell them to fend for themselves, or whether we keep strengthening our social safety net and our health care system. 由你们来选择我们是继续受制于油价波动，还是投资于能够打破我们对石油的依赖并保护地球的清洁能源。由你们来选择我们是违背对老年人、穷人和残疾人的承诺，让他们自谋生路，还是继续加强我们的社会安全网和医疗保健系统。
And it will be up to you whether we'll turn on one another, or whether we stay true to our values of fairness and opportunity, understanding that we are a nation of immigrants -- immigrants that built this country into an economic powerhouse and a beacon of hope around the world. 由你们来决定我们是互相攻击，还是坚守我们对公平和机会的价值观，理解我们是一个移民国家——移民们将这个国家建设成为经济强国和世界各地的希望灯塔。
I know this last issue generates some passion. I know that several young people here have recently identified themselves as undocumented. Some were brought here as young children, and discovered the truth only as adults. And they've put their futures on the line in hopes it will spur the rest of us to live up to our most cherished values. 我知道这最后一个议题引发了一些热情。我知道这里的几位年轻人最近表明自己是无证移民。他们中的一些人在年幼时被带到这里，直到成年才发现真相。他们冒着自己未来的风险，希望这能激励我们其他人践行我们最珍视的价值观。
I strongly believe we should fix our broken immigration system. Fix it so that it meets our 21st-century economic and security needs. And I want to work with Democrats and Republicans, yes, to protect our borders, and enforce our laws, and address the status of millions of undocumented workers. And I will keep fighting alongside many of you to make the DREAM Act the law of the land. 我坚信我们应该修复我们破碎的移民制度。修复它，使其满足我们21世纪的经济和安全需求。我想与民主党和共和党合作，是的，保护我们的边境，执行我们的法律，解决数百万无证工人的身份问题。我将继续与你们中的许多人一起奋斗，使梦想法案成为国家法律。
Like all of this country's movements towards justice, it will be difficult and it will take time. I know some here wish that I could just bypass Congress and change the law myself. But that's not how democracy works. See, democracy is hard. But it's right. 就像这个国家所有争取正义的运动一样，这将是困难的，也需要时间。我知道这里有些人希望我能绕过国会，自己修改法律。但民主不是这样运作的。看，民主很难。但它是正确的。
Changing our laws means doing the hard work of changing minds and changing votes, one by one. And I am convinced we can change the laws, because we should all be able to agree that it makes no sense to expel talented young people from our country. They grew up as Americans. They pledge allegiance to our flag. And if they are trying to serve in our military or earn a degree, they are contributing to our future -- and we welcome those contributions. 修改法律意味着做艰苦的工作，一个接一个地改变想法和改变投票。我确信我们可以改变法律，因为我们应该都能同意，将有才华的年轻人驱逐出我们的国家是毫无意义的。他们作为美国人长大。他们向我们的国旗宣誓效忠。如果他们试图在我们的军队服役或获得学位，他们就是在为我们的未来做贡献——我们欢迎这些贡献。
We didn't raise the Statue of Liberty with its back to the world; we raised it with its light to the world. Whether your ancestors came here on the Mayflower or a slave ship; whether they signed in at Ellis Island or they crossed the Rio Grande -- we are one people. We need one another. Our patriotism is not rooted in ethnicity, but in a shared belief of the enduring and permanent promise of this country. 我们竖起自由女神像时不是让它背对世界；我们让它面向世界，照亮世界。无论你们的祖先是乘坐五月花号还是奴隶船来到这里；无论他们是在埃利斯岛登记入境还是穿越格兰德河——我们是一个民族。我们需要彼此。我们的爱国主义不是植根于种族，而是植根于对这个国家持久和永恒承诺的共同信念。
That's the promise redeemed by your graduation today. That's the promise that drew so many of you to this college and your parents to this country. And that's the promise that drew my own father here. 这就是你们今天的毕业所兑现的承诺。这就是吸引你们这么多人来到这所学院、吸引你们的父母来到这个国家的承诺。这就是吸引我父亲来到这里的承诺。
I didn't know him well, my father -- and he lived a troubled life. But I know that when he was around your age, he dreamed of something more than his lot in life. He dreamed of that magical place; he dreamed of coming to study in America. 我不太了解我的父亲——他过着坎坷的生活。但我知道当他在你们这个年纪时，他梦想着比他的命运更多的东西。他梦想着那个神奇的地方；他梦想着来美国学习。
And when I was around your age, I traveled back to his home country of Kenya for the first time to learn his story. And I went to a tiny village called Alego, where his stepmother still lives in the house where he grew up, and I visited his grave. And I asked her if there was anything left for me to know him by. 当我在你们这个年纪时，我第一次回到他的祖国肯尼亚，去了解他的故事。我去了一个叫阿莱戈的小村庄，他的继母仍然住在他长大的房子里，我参观了他的坟墓。我问她是否还有什么能让我了解他的东西。
And she opened a trunk, and she took out a stack of letters -- and this is an elderly woman who doesn't read or write -- but she had saved these letters, more than 30 of them, written in his hand and addressed to colleges and universities all across America. 她打开了一个箱子，拿出了一叠信件——这是一位不识字的老妇人——但她保存了这些信件，超过30封，是他亲笔写的，寄给美国各地的学院和大学。
They weren't that different from the letters that I wrote when I was trying to get into college, or the ones that you wrote when you were hoping to come here. They were written in the simple, sometimes awkward, sometimes grammatically incorrect, unmistakably hopeful voice of somebody who is just desperate for a chance -- just desperate to live his unlikely dream. 它们和我上大学时写的信没什么不同，也和你们希望来这里时写的信没什么不同。它们是用简单、有时笨拙、有时语法不正确的、但无疑是充满希望的语气写的，出自一个极度渴望机会的人——一个极度渴望实现他不太可能的梦想的人。
And somebody at the University of Hawaii -- halfway around the world -- chose to give him that chance. And because that person gave a young man a chance, he met a young woman from Kansas; they had a son in the land where all things are possible. 而夏威夷大学的某个人——在地球的另一端——选择给他那个机会。因为那个人给了一个年轻人机会，他遇到了一位来自堪萨斯的年轻女子；他们在一切皆有可能的国度生了一个儿子。
And one of my earliest memories from growing up in Hawaii, is of sitting on my grandfather's shoulders to see the astronauts from one of the Apollo space missions come ashore after a successful splashdown. You remember that no matter how young you are as a child. It's one of those unforgettable moments when you first realize the miracle that is what this country is capable of. And I remember waving a little American flag on top of my grandfather's shoulders, thinking about those astronauts, and thinking about space. 我在夏威夷长大的最早记忆之一，是骑在外祖父的肩膀上，看阿波罗太空任务的宇航员在成功溅落后上岸。无论你小时候多小，你都会记住那一刻。那是你第一次意识到这个国家所能创造的奇迹时的难忘时刻之一。我记得在外祖父的肩膀上挥舞着一面小小的美国国旗，想着那些宇航员，想着太空。
And today, on this day, more than 40 years later, I took my daughters to the Kennedy Space Center. And even though we didn't get to see the Space Shuttle Endeavour launch, we met some of the astronauts, and we toured the Space Shuttle Atlantis. And looking at my daughters, I thought of how things come full circle. I thought of all that we've achieved as a nation since I was their age, a little brown boy sitting on my grandfather's shoulders -- and I thought about all I want us to achieve by the time they have children of their own. 今天，在这一天，40多年后，我带我的女儿们去了肯尼迪航天中心。虽然我们没能看到奋进号航天飞机发射，但我们见到了一些宇航员，还参观了亚特兰蒂斯号航天飞机。看着我的女儿们，我想到了事物是如何回到原点的。我想到了自从我在她们这个年纪——一个骑在外祖父肩膀上的棕色皮肤的小男孩——以来我们作为一个国家所取得的一切成就，我想到了我希望在她们有了自己的孩子之前我们能取得的一切成就。
That's my proof that the idea of America endures. That's my evidence that our brave endeavor on this Earth continues. And every single day I walk into the Oval Office, and for all the days of my life, I will always remember that in no other nation on Earth could my story be possible, could your stories be possible. That is something I celebrate. That is something that drives every decision I make. 这就是美国理念经久不衰的证明。这就是我们在这个地球上勇敢探索仍在继续的证据。每一天我走进椭圆形办公室，在我生命的每一天，我都将永远记住，在地球上没有其他国家能让我的故事成为可能，能让你们的故事成为可能。这是我庆祝的事情。这是我做出每一个决定的动力。
So what I ask of you, graduates, as you walk out of here today is this: Pursue success. Do not falter. When you make it, pull somebody else up. Preserve our dream. 所以我要求你们，毕业生们，当你们今天走出这里时：追求成功。不要犹豫。当你成功时，拉别人一把。保护我们的梦想。
Remember your life is richer when people around you have a shot at opportunity as well. Strive to widen that circle of possibility; strive to forge that big, generous, optimistic vision of America that we inherited; strive to carry that dream forward to future generations. 记住，当你周围的人也有机会时，你的生活会更加丰富。努力扩大可能性的圈子；努力锻造我们继承的那个宏大、慷慨、乐观的美国愿景；努力将这个梦想传递给后代。
Thank you. Congratulations. May God bless you. May God bless the United States of America. 谢谢。祝贺你们。愿上帝保佑你们。愿上帝保佑美利坚合众国。
