And I know you didn‘t do this just to win an election. And I know you didn’t do it for me.You did it because you understand the enormity of the task that lies ahead. For even as we celebrate tonight， we know the challenges that tomorrow will bring are the greatest of our lifetime — two wars， a planet in peril， the worst financial crisis in a century.
余知诸君之意非在此一选举，亦非在鄙人一身。盖瞻前路之艰辛，益知此任非同小可也。虽今夕欢贺于此，而明朝酒醒，大患仍自当前，不容有怠——两地烽烟熊熊而起，四海之内纷纷而乱，金融业界惶惶而不得宁。

Even as we stand here tonight， we know there are brave Americans waking up in the deserts of Iraq and the mountains of Afghanistan to risk their lives for us.There are mothers and fathers who will lie awake after the children fall asleep and wonder how they‘ll make the mortgage or pay their doctors’ bills or save enough for their child‘s college education. There’s new energy to harness， new jobs to be created， new schools to build， and threats to meet， alliances to repair.
是夜，饮宴笙歌之声不绝于耳，而异邦大漠群山中，吾国大好青年，兀自苦戍边塞，惝恍竟夜，性命尚未得安。吾国千万庶民，为人父母者，兀自惴惴难眠，所忧者，乃房宅所贷、病患之费、抚育之资也。至若吾国能源之耗，百业之兴，庠序之教，攻伐之术，怀远之道，亦皆吾等忡忡挂怀者也。

The road ahead will be long. Our climb will be steep. We may not get there in one year or even in one term. But， America， I have never been more hopeful than I am tonight that we will get there. I promise you， we as a people will get there.

渺渺乎其远，如不可达，危危乎其高，若不可攀。朝夕岁月，焉得成就？余不揣愚钝，愿以四载韶华，付诸此业，胜算何如虽不可知，然昂扬必胜之奇志，成就伟业之壮怀，平生未之有也。君子一诺，其重何如，此地今夕，愿斗胆发一狂言——吾辈既在，其事必成！

There will be setbacks and false starts. There are many who won‘t agree with every decision or policy I make as president. And we know the government can’t solve every problem. But I will always be honest with you about the challenges we face. I will listen to you， especially when we disagree. And， above all， I will ask you to join in the work of remaking this nation， the only way it‘s been done in America for 221 years — block by block， brick by brick， calloused hand by calloused hand.
逶迤坎坷，份内之事。异见争端，料必有之。国中之政府，谅非无所不能者。余所秉承不移者，唯忠信矣。倘有危难于前，必无欺瞒于世。诸君言论臧否，纵悖逆相左之议，余必当洗耳以聆。于此之外，更当恳请诸君，不吝心血，致力报效，以振吾美利坚重兴之业。余亦别无他想，唯盼吾侪协力，延继吾国既肇二百二十一年之大统，汇涓滴之力，而成万世之业。

What began 21 months ago in the depths of winter cannot end on this autumn night. This victory alone is not the change we seek. It is only the chance for us to make that change. And that cannot happen if we go back to the way things were. It can‘t happen without you， without a new spirit of service， a new spirit of sacrifice.
昔年冬日，余有志于斯，投身此业，屈指算来，倏然近二载矣。当此秋夜，追思反省，仍无溃退逃亡之意。选战之胜，无非一役之功，余梦寐所思矢志所求者，非在乎此。溯源究本，此役之胜，不过革世变时一大好良机耳。倘止步于斯，垂手而待，或无诸君倾力相援，则壮志丰功，无非泡影，诸般梦想，终必虚妄。

So let us summon a new spirit of patriotism， of responsibility， where each of us resolves to pitch in and work harder and look after not only ourselves but each other. Let us remember that， if this financial crisis taught us anything， it‘s that we cannot have a thriving Wall Street while Main Street suffers. In this country， we rise or fall as one nation， as one people.
爱国之心，报国之念，吾人固有之，然逢今日之世，此心此念亦当一变——吾辈各执己业，益当各竭其力，各尽其命，非但为一己之利，而更期普世之荣。今岁，金融业界动荡多舛，细审观之，当可以之为鉴——实业之损，亦是金融之伤。可知，既在邦域之内，吾辈荣辱休戚，皆相与共矣！
