While our Nation is safer than it was seven years ago, the gravest threat to our people remains another terrorist attack. Our enemies are patient and determined to strike again. America did nothing to seek or deserve this conflict. But we have been given solemn responsibilities, and we must meet them. We must resist complacency. We must keep our resolve. And we must never let down our guard.

　　尽管我们的国家要比7年前更为安全，但目前美国最严峻的威胁仍然是另一场恐怖袭击。我们的敌人十分耐心，并且决心要再次发动袭击。美国没有故意挑起冲突。但是我们肩负着庄严的责任，必须同恐怖主义作斗争。我们不能骄傲自满，我们要坚定决心，我们绝不能放松警惕。

　　At the same time, we must continue to engage the world with confidence and clear purpose. In the face of threats from abroad, it can be tempting to seek comfort by turning inward. But we must reject isolationism and its companion, protectionism. Retreating behind our borders would only invite danger. In the 21st century, security and prosperity at home depend on the expansion of liberty abroad. If America does not lead the cause of freedom, that cause will not be led.

　　与此同时，我们必须带着信心和清晰的目标参与世界事务。面对来自海外的威胁，在国内寻求安慰是一种诱人的举措。但是我们必须拒绝孤立主义与保护主义。退缩只会找来危险。在21世纪，国内的安全和繁荣需要依靠国外自由的扩展。如果美国不领导自由事业，那么自由事业就将无所适从。

　　As we address these challenges - and others we cannot foresee tonight - America must maintain our moral clarity. I have often spoken to you about good and evil. This has made some uncomfortable. But good and evil are present in this world, and between the two there can be no compromise. Murdering the innocent to advance an ideology is wrong every time, everywhere. Freeing people from oppression and despair is eternally right. This Nation must continue to speak out for justice and truth. We must always be willing to act in their defense and to advance the cause of peace.

　　一方面我们在处理这些眼前和未来的挑战，另一方面美国必须保持自己在道义上的明确性。我经常谈及善恶问题，这令一些人颇感不适。但是目前这个世界确实存在着善恶双方，而且双方之间无法达成妥协。通过谋杀无辜来宣扬某种意识形态无论在何时何地都是错误的。将人们从压迫与绝望中解救出来是永远正确的。美国必须坚持为正义与真理而呼喊，我们必须保护正义与真理，并且推动和平事业的发展。

　　President Thomas Jefferson once wrote, "I like the dreams of the future better than the history of the past." As I leave the house he occupied two centuries ago, I share that optimism. America is a young country, full of vitality, constantly growing and renewing itself. And even in the toughest times, we lift our eyes to the broad horizon ahead.

　　托马斯-杰斐逊曾写到：“相比于过去的历史，我更喜欢未来的梦想。”随着我马上要离开白宫，我赞同杰斐逊这样的乐观精神。美国是一个年轻的国家，充满了活力，不断发展与更新。即便在最艰难的时候，美国仍然没有放弃对未来的梦想。

　　I have confidence in the promise of America because I know the character of our people. This is a Nation that inspires immigrants to risk everything for the dream of freedom. This is a Nation where citizens show calm in times of danger and compassion in the face of suffering. We see examples of America's character all around us. And Laura and I have invited some of them to join us in the White House this evening.

　　我了解我们民族的特质，因此我也相信美国的明天会更美好。这是一个鼓励移民们为自由的梦想而去尝试一切事情的国家，这是一个在面对危险使仍然镇定的国家，这是一个面对苦难仍抱有同情心的国家。我们在身边的每一个人身上都可以看到美国的特征。今晚，受我和夫人劳拉的邀请，一切代表也来到了白宫。

　　We see America's character in Dr. Tony Recasner, a principal who opened a new charter school from the ruins of Hurricane Katrina. We see it in Julio Medina, a former inmate who leads a faith-based program to help prisoners returning to society. We see it in Staff Sergeant Aubrey McDade, who charged into an ambush in Iraq and rescued three of his fellow Marines.

　　我们看到里卡斯钠博士的美国特质，这位校长在卡特里娜飓风的废墟中开办一所新的特许学校。我们看到麦地那身上的美国特质，这位前囚犯带领一个以信仰为基础的项目，帮助囚犯重回社会。我们在上士麦达德身上的美国特质，他负责伊拉克的一次埋伏并拯救了三名同伴的海军陆战队队员。

　　We see America's character in Bill Krissoff, a surgeon from California. His son Nathan, a Marine, gave his life in Iraq. When I met Dr. Krissoff and his family, he delivered some surprising news: He told me he wanted to join the Navy Medical Corps in honor of his son. This good man was 60 years old – 18 years above the age limit. But his petition for a waiver was granted, and for the past year he has trained in battlefield medicine. Lieutenant Commander Krissoff could not be here tonight, because he will soon deploy to Iraq, where he will help save America's wounded warriors and uphold the legacy of his fallen son.

　　我在外科医生克里索夫身上看到了美国人民的伟大个性。克里索夫的儿子，一名海军，在伊拉克光荣地献出了自己的生命。当我见到克里索夫和他家人的时候，他告诉了我一个惊人的消息：他告诉我，为了缅怀儿子，他希望加入美国海军医疗团。克里索夫已经60岁了，超过了年龄限制，但是他的申请得到了批准。在过去的一年中，克里索夫接受了良好的训练，但已经荣升少校的他今晚不能来到这里，他很快就会前往伊拉克，在那里他可以救助我们受伤的勇士并继续他儿子为完成的事业。

　　In citizens like these, we see the best of our country – resilient and hopeful, caring and strong. These virtues give me an unshakable faith in America. We have faced danger and trial, and there is more ahead. But with the courage of our people and confidence in our ideals, this great Nation will never tire … never falter … and never fail.

　　同时，从美国公民身上，我看到了我们国家优秀的一面-我们的国家充满关怀和希望，这样的优点令我对国家有着坚贞的信念。我们面临着危险和审判，而且在未来我们仍将需要应对更多的挑战。然而，依靠你们的勇气和信心，伟大的美国永远会稳如磐石，从来不会走向没落。

　　It has been the privilege of a lifetime to serve as your President. There have been good days and tough days. But every day I have been inspired by the greatness of our country and uplifted by the goodness of our people. I have been blessed to represent this Nation we love. And I will always be honored to carry a title that means more to me than any other: citizen of the United States of America.

　　对我来说，能够担任你们的总统，是我一生的荣耀。我有过欢乐也有过困苦。但是，每天我都会受到伟大祖国的鼓舞，并且我也一直在为我们的国家祈祷。在以后的时光里，我会永远珍视这样一段话：美利坚合众国的公民。

　　And so, my fellow Americans, for the final time: Good night. May God bless this house and our next President. And may God bless you and our wonderful country.

　　我亲爱的同胞们，我的演说就到这里了，晚安！愿上帝保佑奥巴马！愿上帝保佑你和我们美好的国家！
