OBAMA: My fellow citizens:

I stand here today humbled by the task before us, grateful for the trust you have bestowed, mindful of the sacrifices borne by our ancestors. I thank President Bush for his service to our nation, as well as the generosity and cooperation he has shown throughout this transition.

Forty-four Americans have now taken the presidential oath. The words have been spoken during rising tides of prosperity and the still waters of peace. Yet, every so often the oath is taken amidst gathering clouds and raging storms. At these moments, America has carried on not simply because of the skill or vision of those in high office, but because we the people have remained faithful to the ideals of our forebears, and true to our founding documents.

So it has been. So it must be with this generation of Americans.

That we are in the midst of crisis is now well understood. Our nation is at war, against a far-reaching network of violence and hatred. Our economy is badly weakened, a consequence of greed and irresponsibility on the part of some, but also our collective failure to make hard choices and prepare the nation for a new age. Homes have been lost; jobs shed; businesses shuttered. Our health care is too costly; our schools fail too many; and each day brings further evidence that the ways we use energy strengthen our adversaries and threaten our planet.

These are the indicators of crisis, subject to data and statistics. Less measurable but no less profound is a sapping of confidence across our land, a nagging fear that Americas decline is inevitable, and that the next generation must lower its sights.

Today I say to you that the challenges we face are real. They are serious and they are many. They will not be met easily or in a short span of time. But know this, America, they will be met.

On this day, we gather because we have chosen hope over fear, unity of purpose over conflict and discord.

On this day, we come to proclaim an end to the petty grievances and false promises, the recriminations and worn out dogmas, that for far too long have strangled our politics.

We remain a young nation, but in the words of scripture, the time has come to set aside childish things. The time has come to reaffirm our enduring spirit; to choose our better history; to carry forward that precious gift, that noble idea, passed on from generation to generation: the God-given promise that all are equal, all are free and all deserve a chance to pursue their full measure of happiness.

In reaffirming the greatness of our nation, we understand that greatness is never a given. It must be earned. Our journey has never been one of shortcuts or settling for less. It has not been the path for the faint-hearted -- for those who prefer leisure over work, or seek only the pleasures of riches and fame. Rather, it has been the risk-takers, the doers, the makers of things -- some celebrated but more often men and women obscure in their labor, who have carried us up the long, rugged path towards prosperity and freedom.

For us, they packed up their few worldly possessions and traveled across oceans in search of a new life.

For us, they toiled in sweatshops and settled the West; endured the lash of the whip and plowed the hard earth.

For us, they fought and died, in places like Concord and Gettysburg; Normandy and Khe Sahn.

我的同胞们，

今天我站在这里，看到眼前面临的重大任务，深感卑微。我感谢你们对我的信任，也知道先辈们为了这个国家所作的牺牲。我要感谢布什总统为国家做出的贡献，以及感谢他在两届政府过渡期间给与的慷慨协作。

迄今为止，已经有44个美国总统宣誓就职。总统的宣誓有时面对的是国家的和平繁荣，但通常面临的是乌云密布的紧张形势。在紧张的形势中，支持美国前进的不仅仅是领导人的能力和远见，也在于美国人民对国家先驱者理想的信仰，以及对美国立国文件的忠诚。

前辈们如此，我们这一代美国人也要如此。

现在我们都深知，我们身处危机之中。我们的国家在战斗，对手是影响深远的暴力和憎恨;国家的经济也受到严重的削弱，原因虽有一些人的贪婪和不负责任，但更为重要的是我们作为一个整体在一些重大问题上决策失误，同时也未能做好应对新时代的准备。

我们的人民正在失去家园，失去工作，很多且要倒闭。社会的医疗过于昂贵、学校教育让许多人失望，而且每天都会有新的证据显示，我们利用能源的方式助长了我们的敌对势力，同时也威胁着我们的星球。

统计数据的指标传达着危机的消息。危机难以测量，但更难以测量的是其对美国人国家自信的侵蚀——现在一种认为美国衰落不可避免，我们的下一代必须低调的言论正在吞噬着人们的自信。

今天我要说，我们的确面临着很多严峻的挑战，而且在短期内不大可能轻易解决。但是我们要相信，我们一定会度过难关。

今天，我们在这里齐聚一堂，因为我们战胜恐惧选择了希望，摒弃了冲突和矛盾而选择了团结。

今天，我们宣布要为无谓的摩擦、不实的承诺和指责画上句号，我们要打破牵制美国政治发展的若干陈旧教条。

美国仍是一个年轻的国家，借用《圣经》的话说，放弃幼稚的时代已经到来了。重拾坚韧精神的时代已经到来，我们要为历史作出更好的选择，我们要秉承历史赋予的宝贵权利，秉承那种代代相传的高贵理念：上帝赋予我们每个人以平等和自由，以及每个人尽全力去追求幸福的机会。

在重申我们国家伟大之处的同时，我们深知伟大从来不是上天赐予的，伟大需要努力赢得。(我们的民族一路走来)，这旅途之中从未有过捷径或者妥协，这旅途也不适合胆怯之人、或者爱安逸胜过爱工作之人、或者单单追求名利之人。这条路是勇于承担风险者之路，是实干家、创造者之路。这其中有一些人名留青史，但是更多的人却在默默无闻地工作着。正是这些人带领我们走过了漫长崎岖的旅行，带领我们走向富强和自由。

为了我们，先辈们带着微薄的细软，横渡大洋，寻找新生活;为了我们，先辈们忍辱负重，用血汗浇铸工厂;为了我们，先辈们在荒芜的西部大地辛勤耕作，定居他乡;为了我们，先辈们奔赴(独立战争中的)康科德城和葛底斯堡、(二战中的)诺曼底、(越战中的)Khe Sahn，他们征战、死去。
