As excited as all of you are today, there's a group here that is beaming with pride and that deserves a big round of applause – your parents and your families. 今天大家都很兴奋，但现场还有一群人满怀骄傲，值得我们热烈鼓掌——你们的父母和家人。
You've been very lucky to study at a place that attracts some of the brightest minds in the world. And during your time here, MIT has extended its tradition of groundbreaking research and innovation. Most of you were here when LIGO proved that Einstein was right about gravitational waves, something that I – as a Johns Hopkins engineering graduate – claimed all along. 你们很幸运，能在一所汇聚世界上最聪明头脑的学府学习。你们在校期间，麻省理工学院延续了突破性研究和创新的传统。你们多数人都在这里见证了激光干涉引力波天文台证实爱因斯坦关于引力波的论断。而我，作为约翰斯·霍普金斯大学的工程学毕业生，早就说过他是对的。
And just this spring, MIT scientists and astronomers helped to capture the first-ever image of a black hole. Those really are incredible accomplishments for MIT. 就在今年春天，麻省理工的科学家和天文学家还帮助拍摄了史上第一张黑洞照片。这些确实是麻省理工了不起的成就。
All of you are part of an amazing institution that has proven – time and time again – that human knowledge and achievement is limitless. In fact, this is the place that proved moonshots are worth taking. 你们都属于这所非凡的学府。它一次又一次证明，人类的知识与成就没有极限。事实上，正是这里证明了向看似遥不可及的目标发起挑战是值得的。
Fifty years ago next month, the Apollo 11 lunar module touched down on the moon. It's fair to say the crew never would have gotten there without MIT. I don't just mean that because Buzz Aldrin was class of '63 here, and took Richard Battin's famous astro-dynamics course. As Chairman Millard mentioned, the Apollo 11 literally got there thanks to its navigation and control systems that were designed right here at what is now the Draper Laboratory. 下个月，阿波罗十一号登月舱在月球着陆就满五十年了。可以说，没有麻省理工，宇航员根本到不了那里。我说的不仅仅是因为巴兹·奥尔德林是一九六三届校友，还上过理查德·巴廷著名的天体动力学课程。正如米勒德主席所说，阿波罗十一号真能抵达月球，靠的正是在今天的德雷珀实验室所在地设计的导航与控制系统。
Successfully putting a man on the moon required solving so many complex problems. How to physically guide a spacecraft on a half-million-mile journey was arguably the biggest one, and your fellow alums and professors solved it by building a one-cubic-foot computer at the time when computers were giant machines that filled whole rooms. 成功把人送上月球，需要解决许多复杂难题。其中最大的难题，也许是怎样实际引导飞船完成五十万英里的旅程。你们的校友和教授给出了答案：在计算机还是占满整间屋子的庞大机器时，他们造出了一台只有一立方英尺的计算机。
The only reason those MIT engineers even tried to build that computer in the first place was that they had been asked to help do something that people thought was either impossible or unnecessary. 那些麻省理工工程师之所以一开始就尝试制造这台计算机，只因有人请他们协助完成一件当时被认为不可能或没有必要的事。
Going to the moon was not a popular idea back in the 1960s. And Congress didn't want to pay for it. Imagine that, a Congress that didn't want to invest in science. Go figure – that would never happen today. 在二十世纪六十年代，登月并不是一个受欢迎的主意。国会也不愿为它拨款。想象一下，一个不愿投资科学的国会。真奇怪——今天绝不会发生这种事，对吧。
President Kennedy needed to persuade the taxpayers that a manned mission to the moon was possible and worth doing. So in 1962, he delivered a speech that inspired the country. He said, ‘We choose to go to the moon this decade, and do the other things, not because they are easy, but because they are hard.’ 肯尼迪总统必须让纳税人相信，载人登月既可行又值得。因此，一九六二年，他发表了一篇激励全国的演讲。他说：“我们选择在这个十年登上月球，并做其他事情，不是因为它们容易，而是因为它们艰难。”
In that one sentence, Kennedy summed up mankind's inherent need to reach for the stars. He continued by saying, ‘That challenge is one that we are willing to accept, one we are unwilling to postpone, and which we intend to win.’ 肯尼迪用这句话概括了人类探索星空的内在渴望。他接着说：“这一挑战，我们愿意接受，不愿推迟，并决心赢得胜利。”
In other words, for the good of the United States, and humanity, it had to be done. And he was right. Neil Armstrong took a great leap for mankind, the U.S. won a major Cold War victory, and a decade of scientific innovation led to an unprecedented era of technological advancement. 换言之，为了美国和全人类的福祉，这件事非做不可。他说得对。尼尔·阿姆斯特朗迈出了人类的一大步，美国赢得了冷战中的一场重大胜利，而十年的科学创新开启了技术进步空前的时代。
The inventions that emerged from that moonshot changed the world: satellite television, computer microchips, CAT scan machines, and many other things we now take for granted – even video game joysticks. 那次登月壮举催生的发明改变了世界：卫星电视、计算机微芯片、计算机断层扫描仪，以及许多我们如今习以为常的东西，甚至包括电子游戏操纵杆。
The world we live in today is fundamentally different, not just because we landed on the moon, but because we tried to get there in the first place. In hindsight, President Kennedy’s call for the original moonshot at exactly the right moment in history was brilliant. And the brightest minds of their generation – many of them MIT graduates – delivered. 今天的世界有了根本变化，不仅因为我们登上了月球，也因为我们当初首先尝试了这件事。回头看，肯尼迪总统在那个历史时刻发出首次登月号召，实在高明。那一代最杰出的人才，其中许多是麻省理工毕业生，也不负所托。
Today, I believe that we are living in a similar moment. And once again, we'll be counting on MIT graduates – all of you – to lead us. 今天，我相信我们正处于一个相似的时刻。我们将再次依靠麻省理工毕业生——你们所有人——引领前路。
But this time, our most important and pressing mission – your generation's mission – is not only to explore deep space and reach faraway places. It is to save our own planet, the one that we're living on, from climate change. And unlike 1962, the primary challenge before you is not scientific or technological. It is political. 但这一次，我们最重要、最紧迫的使命，也就是你们这一代人的使命，并非只是在深空探索，抵达遥远的地方。它是拯救我们居住的地球，使其免受气候变化的危害。与一九六二年不同，你们面前的主要挑战不是科学或技术，而是政治。
The fact is we've already pioneered the technology to tackle climate change. We know how to power buildings using sun and wind. We know how to power vehicles using batteries charged with renewable energy. We know how to power factories and industry using hydrogen and fuel cells. And we know that these innovations don't require us to sacrifice financially or economically. Just the opposite, these investments, on balance, create jobs and save money. 事实上，我们已经率先开发出应对气候变化的技术。我们知道如何用太阳能和风能为建筑供电，如何用可再生能源充电的电池驱动车辆，如何用氢能和燃料电池为工厂和工业供能。我们也知道，这些创新不要求我们付出经济或财务牺牲。恰恰相反，整体而言，这些投资会创造就业并节省开支。
Yes, all of those power sources need to be brought to scale – and that will require further scientific innovation which we need you to help lead. But the question isn't how to tackle climate change. We've known how to do that for many years. The question is: why the hell are we moving so slowly? 没错，所有这些能源都需要扩大应用规模，而这需要进一步的科学创新，也需要你们参与引领。但问题不是如何应对气候变化。多年来，我们一直知道该怎么做。问题是：我们到底为什么行动得这么慢？
The race we are in is against time, and we are losing. And with each passing year, it becomes clearer just how far behind we've fallen, how fast the situation is deteriorating, and how tragic the results can be. 我们正在与时间赛跑，而且正在落后。每过一年，我们落后了多远、局势恶化得多快、后果可能多么悲惨，就变得更加清楚。
In the past decade alone, we've seen historic hurricanes devastate islands across the Caribbean. We've seen ‘thousand-year floods’ hit the Midwestern and Southern United States multiple times in a decade. We've seen record-breaking wildfires ravage California, and record-breaking typhoons kill thousands in the Philippines. 仅在过去十年，我们就看到历史性的飓风摧毁加勒比海各岛屿；所谓“千年一遇”的洪水，在美国中西部和南部十年内多次发生；创纪录的野火肆虐加利福尼亚，创纪录的台风在菲律宾夺去数千人的生命。
This is a true crisis. If we fail to rise to the occasion, your generation, your children, and grandchildren will pay a terrible price. So scientists know there can be no delay in taking action – and many governments and political leaders around the world are starting to understand that. 这是一场真正的危机。如果我们不能迎接挑战，你们这一代、你们的孩子和孙辈都将付出惨痛代价。因此，科学家知道，行动刻不容缓；世界各地许多政府和政治领袖也开始认识到这一点。
Yet here in the United States, our federal government is seeking to become the only country in the world to withdraw from the Paris Climate Agreement. The only one. Not even North Korea is doing that. 然而在美国，联邦政府正试图让我们成为世界上唯一退出《巴黎气候协定》的国家。唯一的一个。连朝鲜都没有这样做。
Those in Washington who deny the science of climate change are no more based in reality than those who believe the moon landing was faked. And while the moon landing conspiracy theorists are relegated to the paranoid corners of talk radio, climate skeptics occupy the highest positions of power in the United States government. 华盛顿那些否认气候变化科学的人，与相信登月造假的人一样脱离现实。相信登月阴谋论的人被挤到谈话电台偏执的角落，怀疑气候科学的人却占据美国政府的最高权力职位。
Now, in the administration's defense: climate change, they say, is only a theory. Yeah, like gravity is only a theory. 现在，替本届政府辩护的人说，气候变化终究只是一种理论。是啊，就像重力也只是一种理论。
People can ignore gravity at their own risk, at least until they hit the ground. But when they ignore the climate crisis they are not only putting themselves at risk, they are putting all humanity at risk. 人们可以不理会重力，自己承担风险，至少在摔到地上之前如此。但他们忽视气候危机时，置于危险中的不仅是自己，还有整个人类。
Instead of challenging Americans to believe in our ability to master the universe, as President Kennedy did, the current administration is pandering to the skeptics who, in the 1960s, looked at the space program and only saw short-term costs, not long-term benefits. 肯尼迪总统曾激励美国人相信我们有能力掌握宇宙；现任政府却迎合那些怀疑论者。这些人在二十世纪六十年代看待太空计划时，只看到眼前成本，看不到长远利益。
President Kennedy's era earned the nickname, ‘The Greatest Generation’ – not only because they persevered through the Great Depression and won the Second World War. They earned it because of determination to rise, to pioneer, to innovate, and to fulfill the promise of American freedom. 肯尼迪时代的一代人赢得了“最伟大的一代”这个称号，不只是因为他们熬过大萧条、赢得第二次世界大战，还因为他们决心奋起、开拓、创新，兑现美国自由的承诺。
They dreamed in moonshots. They reached for the stars. And they began to redeem – through the civil rights movement – the failures of the past. They set the standard for leadership and service to our nation's ideals. 他们梦想完成登月般的壮举，伸手摘取星辰，并通过民权运动开始弥补过去的过失。他们为领导力和服务国家理想树立了标准。
Now, your generation has the opportunity to join them in the history books. The challenge that lies before you – stopping climate change – is unlike any other ever faced by humankind. The stakes could not be higher. 现在，你们这一代有机会与他们一道载入史册。摆在你们面前的挑战——阻止气候变化——是人类从未面对过的。其利害之重大，无以复加。
If left unchecked, the climate change crisis threatens to destroy oceanic life that feeds so many people on this planet. It threatens to breed war by spreading drought and hunger. It threatens to sink coastal communities, devastate farms and businesses, and spread disease. 如果任其发展，气候危机可能毁掉养活地球上无数人的海洋生物；可能因旱灾与饥荒蔓延而引发战争；可能淹没沿海社区，摧毁农田和企业，并传播疾病。
Now, some people say we should leave it in God's hands. But most religious leaders, I’m happy to say, disagree. After all, where in the Bible, or the Torah, or the Koran, or any other book about faith or philosophy does it teach that we should do things that make floods and fires and plagues more severe? I must have missed that day in religion class. 有人说，我们应该把这一切交到上帝手中。但令我高兴的是，多数宗教领袖并不同意。毕竟，《圣经》《妥拉》《古兰经》，或其他任何信仰和哲学著作，哪里教导我们去做会加重洪水、火灾与瘟疫的事？也许我在宗教课上漏听了那一天的内容。
Today, most Americans in both parties accept that human activity is driving the climate crisis and they want government to take action. Over the past few months, there has been a healthy debate – mostly within the Democratic Party – over what those actions should be. And that's great. 如今，美国两党多数民众都承认，人类活动正在推动气候危机，也希望政府采取行动。过去几个月，关于该采取什么行动，主要在民主党内部展开了有益的辩论。这很好。
In the years ahead, we need to build consensus around comprehensive and ambitious federal policies that the next Congress should pass. But everyone who is concerned about the climate crisis should also be able to agree on two realities. 未来几年，我们需要就全面而有雄心的联邦政策建立共识，推动下一届国会通过。但每个关心气候危机的人，也应该能够认同两个现实。
The first one is given opposition in the Senate and White House, there is virtually no chance of passing such policies before 2021. And the second reality is we can't wait to act. We can't put this mission off any longer. Mother Nature does not wait on the election calendar – and neither can we. 第一，鉴于参议院和白宫的反对，二〇二一年之前通过这类政策几乎没有可能。第二，我们不能等到那时才行动。不能再推迟这项使命。大自然不会等待选举日程，我们也不能。
Our foundation, Bloomberg Philanthropies, has been working for years to rally cities, states, and businesses to lead on this issue – and we've had real success. Just not enough. 我们的基金会——彭博慈善基金会——多年来一直推动城市、各州和企业在这一议题上发挥带头作用，也取得了实实在在的成果。只是还远远不够。
So today, I'm happy to announce that, with our foundation, I am committing $500 million to the launch of a new national climate initiative, and I hope that you will all become part of it. We are calling it Beyond Carbon. The last one was Beyond Coal, this is Beyond Carbon because we have greater goals. 所以今天，我很高兴宣布，我将通过我们的基金会投入五亿美元，启动一项新的全国气候倡议。我希望你们都能参与。我们称它为“超越碳排放”。上一项倡议叫“超越煤炭”；这一次叫“超越碳排放”，因为我们的目标更远大。
And our goal is to move the U.S. toward a 100 percent clean energy economy as expeditiously as possible, and begin that process right now. We intend to succeed not by sacrificing things we need, but by investing in things we want: more good jobs, cleaner air and water, cheaper power, more transportation options, and less congested roads. 我们的目标是尽快推动美国迈向百分之百清洁能源经济，而且现在就开始。我们打算通过投资于人们想要的东西来取得成功，而不是牺牲人们需要的东西：更多好工作，更清洁的空气和水，更便宜的电力，更多交通选择，以及更不拥堵的道路。
To do it, we will defeat in the courts the EPA's attempts to rollback regulations that reduce carbon pollution and protect our air and water. But most of our battles will take place outside of Washington. We are going to take the fight to the cities and states – and directly to the people. And the fight will take place on four main fronts. 为此，我们将在法庭上挫败美国环保署撤销那些减少碳污染、保护空气和水的法规的企图。但我们的大部分行动将在华盛顿之外展开。我们会把斗争带到城市和各州，直接面向公众，并从四条主要战线推进。
First, we will push states and utilities to phase out every last U.S. coal-fired power plant by 2030 – just 11 years from now. Politicians keep making promises about climate change mitigation by the year 2050 – hypocritically, after they're long gone and no one can hold them accountable. Meanwhile, the science keeps moving the possible inflection point of irreversible global warming closer and closer. We have to set goals for the near-term – and we have to hold our elected officials accountable for meeting them. 第一，我们将推动各州和公用事业企业在二〇三〇年前逐步关闭美国最后一座燃煤电厂，也就是从现在起只剩十一年。政客们不断许诺要到二〇五〇年才实现减缓气候变化的目标；那时他们早已离任，没人能追究责任，这很虚伪。与此同时，科学研究不断把全球变暖可能发生不可逆转拐点的时间提前。我们必须制定近期目标，并要求民选官员对实现目标负责。
We know that closing every last U.S. coal-fired power plant over the next 11 years is achievable because we're already more than half-way there. Through a partnership between Bloomberg Philanthropies and the Sierra Club, we've shut down 289 coal-fired power plants since 2011, and that includes 51 that we have retired since the 2016 presidential election despite all the bluster from the White House. As a matter of fact, since Trump got elected the rate of closure has gone up. 我们知道，在未来十一年关闭美国所有剩余燃煤电厂可以做到，因为任务已经完成了一半以上。通过彭博慈善基金会与塞拉俱乐部的合作，自二〇一一年以来，我们已促使二百八十九座燃煤电厂关闭，其中五十一座是在二〇一六年总统选举后退役的，尽管白宫一直高调叫嚷。事实上，特朗普当选后，电厂关闭的速度反而加快了。
Second, we will work to stop the construction of new gas plants. By the time they are built, they will already be out of date – because renewable energy will be cheaper. Cities like Los Angeles are already stopping new gas plant construction in favor of renewable energy, and states like New Mexico, Washington, Hawaii, and California are working to convert their electrical systems to 100 percent clean energy. 第二，我们将努力阻止新建天然气发电厂。等到它们建成，就已经过时了，因为可再生能源会更便宜。洛杉矶等城市已经停止新建天然气发电厂，转而选择可再生能源；新墨西哥州、华盛顿州、夏威夷州和加利福尼亚州等也在努力把电力系统转向百分之百清洁能源。
We don't want to replace one fossil fuel with another. We want to build a clean energy economy – and we will push more states to do that. 我们不想用一种化石燃料取代另一种。我们要建立清洁能源经济，也会推动更多州这样做。
Third, we will support our most powerful allies – governors, mayors, and legislators – in their pursuit of ambitious policies and laws, and we will empower the grassroots army of activists and environmental groups that are currently driving progress state-by-state. 第三，我们将支持最有力的盟友——州长、市长和议员——推行雄心勃勃的政策与法律；也将赋能正在逐州推动进步的基层活动人士和环保组织。
Together, we will push for new incentives and mandates that increase renewable power, pollution-free buildings, waste-free industry, access to mass transit, and sales of electric vehicles, which are now turning the combustion engine – and all of its pollution – into a relic of the industrial revolution. 我们将共同推动新的激励措施和强制规定，扩大可再生能源、无污染建筑、零废弃工业、公共交通覆盖和电动汽车销售。电动汽车正在让内燃机及其造成的污染，成为工业革命时代的遗物。
Fourth, and finally, we will get deeply involved in elections across the country, because climate change is now first and foremost a political problem, not a scientific quandary, or even a technological puzzle. 第四，也是最后一点，我们将深入参与全国各地的选举，因为如今的气候变化首先是一个政治问题，而不是科学难题，甚至也不是技术谜题。
Now, I know that as scientists and engineers, politics can be a dirty word. I'm an engineer – I get it. But I'm also a realist so I have three words for you: get over it. 我知道，作为科学家和工程师，你们可能觉得政治是一个肮脏的词。我也是工程师，我理解。但我也看重现实，所以送你们三个词：克服这种顾虑。
At least for the foreseeable future, winning the battle against climate change will depend less on scientific advancement and more on political activism. 至少在可预见的将来，打赢应对气候变化的战斗，更多取决于政治行动，而不是科学进步。
That’s why Beyond Carbon includes political spending that will mobilize voters to go to the polls and support candidates who actually are taking action on something that could end life on Earth as we know it. And at the same time, we will defeat at the voting booth those who try to block action and those who pander with rhetoric that just kicks the can down the road. 因此，“超越碳排放”计划也包括政治支出，用来动员选民投票，支持真正对这项可能终结我们熟悉的地球生命的威胁采取行动的候选人。与此同时，我们会在投票箱前击败阻挠行动的人，以及那些用空话敷衍、不断把问题往后拖的人。
Our message to elected officials will be simple: face reality on climate change, or face the music on Election Day. Our lives and our children's lives depend on it. And so should their political careers. 我们给民选官员的信息很简单：正视气候变化的现实，否则就在选举日承担后果。我们和孩子的生命取决于此，他们的政治前途也应该取决于此。
Now, most of America will experience a net increase in jobs as we move to renewable energy sources and reductions in pollution. In some places jobs are being lost – we know that, and we can’t leave those communities behind. 随着我们转向可再生能源、减少污染，美国大部分地区的就业岗位净数将增加。但有些地方正在失去工作，我们知道这一点，不能把这些社区抛在后面。
For example, generations of miners powered America to greatness – and many paid for it with their lives and their health. But today they need our help to change with technology and the economy. 例如，几代矿工曾为美国的发展提供动力，许多人为此付出了生命和健康。今天，他们需要我们的帮助，以适应技术和经济的变化。
And while it is up to the federal government to make those investments, Beyond Carbon will continue our foundation's work to show that progress really is possible. So we will support local organizations in Appalachia and the western mountain states and work to spur economic growth and re-train workers for jobs in growing industries. 虽然进行这些投资是联邦政府的责任，“超越碳排放”仍将继续基金会的工作，证明进步确实可以实现。因此，我们会支持阿巴拉契亚地区和西部山区各州的地方组织，推动经济增长，帮助工人接受再培训，进入正在发展的行业。
Taken together, these four elements of Beyond Carbon will be the largest coordinated assault on the climate crisis that our country has ever undertaken. 综合起来，“超越碳排放”的这四项行动将构成我国有史以来针对气候危机规模最大的协同攻势。
We will work to empower and expand the volunteers and activists fighting these battles community by community, state by state. It's a process that our foundation and I have proved can succeed. After all, this isn't the first time we've done an end run around Washington. 我们将帮助那些逐个社区、逐个州投入这场斗争的志愿者和活动人士增强力量、扩大队伍。我和基金会已经证明，这种方式能够成功。毕竟，绕过华盛顿另辟道路，这并不是我们第一次做。
A decade ago no one would have believed that we could take on the coal industry and close half of all U.S. plants. But we have. 十年前，没有人会相信我们能挑战煤炭行业，关闭美国一半的燃煤电厂。但我们做到了。
A decade ago no one would have believed we could take on the NRA and pass stronger gun safety laws in states like Florida, Colorado, and Nevada. But we have. 十年前，没有人会相信我们能挑战全国步枪协会，并在佛罗里达、科罗拉多和内华达等州通过更严格的枪支安全法律。但我们做到了。
Two decades ago, no one would have believed that we could take on the tobacco industry and spread New York City's smoking ban to most of America and to countries around the world. But we have. 二十年前，没有人会相信我们能挑战烟草业，把纽约市的禁烟规定推广到美国大部分地区以及世界各国。但我们做到了。
And now, we will take on the fossil fuel industry to accelerate the transition to a clean energy economy. I believe we will succeed again – but only if one thing happens and that is: you have to help lead the way by raising your voices, by joining an advocacy group, by knocking on doors, by calling your elected officials, by voting, and getting your friends and family to join you. 现在，我们将挑战化石燃料行业，加快向清洁能源经济转型。我相信我们还能成功，但有一个前提：你们必须带头。你们要发声，加入倡议团体，上门动员，致电民选官员，参加投票，并带动亲友一起行动。
Back in the 1960's, when scientists here at MIT were racing to the moon, there was a popular saying that went: if you're not part of the solution you're part of the problem. Today, Washington is a very, very big part of the problem. 二十世纪六十年代，麻省理工的科学家争相奔向月球时，有句流行的话：如果你不是解决问题的一分子，你就是问题的一分子。今天，华盛顿在很大程度上正是问题的一部分。
We have to be part of the solution through political activism that puts the screws to our elected officials. Let me reiterate, this has gone from a scientific challenge to a political one. 我们必须通过政治行动成为解决方案的一部分，向民选官员施加压力。我再说一遍：这已经从科学挑战变成了政治挑战。
It is time for all of us to accept that climate change is the challenge of our time. As President Kennedy said 57 years ago of the moon mission: we are willing to accept this challenge, we are unwilling to postpone it, and we intend to win it. We must again do what is hard. 现在是我们所有人承认气候变化是这个时代重大挑战的时候了。正如肯尼迪总统五十七年前谈到登月使命时所说：我们愿意接受这一挑战，不愿推迟，并决心赢得胜利。我们必须再次选择艰难的事。
Graduates, we need your minds and your creativity to achieve a clean energy future. But that is not all. We need your voices. We need your votes. And we need you to help lead us where Washington will not. It may be a moonshot – but it's the only shot we've got. 毕业生们，要实现清洁能源的未来，我们需要你们的才智和创造力。但这还不够。我们需要你们发声，需要你们投票，需要你们在华盛顿不愿引领的地方带领我们。这或许是一次登月般的壮举，但也是我们唯一的机会。
As you leave this campus I hope you will carry with you MIT's tradition of taking – and making – moonshots. Be ambitious in every facet of your life. And don't ever let something stop you because people say it's impossible. Let those words inspire you. Because just trying to make the impossible possible can lead to achievements you never dreamed of. And sometimes, you actually do land on the moon. 离开校园时，我希望你们带着麻省理工敢于发起、也善于完成登月壮举的传统。在生活的各个方面都怀有雄心。不要因为有人说一件事不可能，就让自己止步。让这句话激励你们。因为仅仅是尝试把不可能变成可能，就能带来你从未梦想过的成就。有时，你们真的能登上月球。
Tomorrow start working on the mission that, if you succeed, will lead the whole world to call you the Greatest Generation, too. 明天，就开始为这项使命工作吧。如果你们成功，全世界也会称你们为“最伟大的一代”。
Thank you, and congratulations. 谢谢大家，祝贺你们。
