I want us to push the boundaries of discovery so that you'll live to see new technologies and inventions that improve our lives and make our planet cleaner and safer.
我要大家向发现的极限挑战，让你在有生之年能够看见改善我们生活、使这个行星更干净、更安全的新科技和发明。
And I want us to push our own human boundaries to reach beyond the divides of race and region, gender and religion that keep us from seeing the best in each other.
我也要大家向自己的人际界限挑战，跨越使我们看不到对方长处的种族、地域、性别和宗教樊篱。
Sometimes we have to send our young men and women into war and other dangerous situations to protect our country--but when we do, I want to make sure that it is only for a very good reason, that we try our best to settle our differences with others peacefully, and that we do everything possible to keep our servicemen and women safe.
有时候为了保护我们的国家，我们不得不把青年男女派到战场或其它危险的地方，然而当我们这么做的时候，我要确保师出有名，我们尽了全力以和平方式化解与他人的争执，也想尽了一切办法保障男女官兵的安全。
And I want every child to understand that the blessings these brave Americans fight for are not free--that with the great privilege of being a citizen of this nation comes great responsibility.
我要每个孩子都明白，这些勇敢的美国人在战场上捍卫的福祉是无法平白得到的：在享有作为这个国家公民的伟大特权之际，重责大任也随之而来。
That was the lesson your grandmother tried to teach me when I was your age, reading me the opening lines of the Declaration of Independence and telling me about the men and women who marched for equality because they believed those words put to paper two centuries ago should mean something.
这正是我在你们这年纪时，外婆想要教我的功课，她把独立宣言开头几行念给我听，告诉我有一些男女为了争取平等挺身而出游行抗议，因为他们认为两个世纪前白纸黑字写下来的这些句子，不应只是空话。
She helped me understand that America is great not because it is perfect but because it can always be made better--and that the unfinished work of perfecting our union falls to each of us. It's a charge we pass on to our children, coming closer with each new generation to what we know America should be.
她让我了解到，美国所以伟大，不是因为它完美，而是因为我们可以不断让它变得更好，而让它更好的未竟工作，就落在我们每个人的身上。这是我们交给孩子们的责任，每过一代，美国就更接近我们的理想。
I hope both of you will take up that work, righting the wrongs that you see and working to give others the chances you've had.
我希望你们俩都愿接下这个工作，看到不对的事要想办法改正，努力帮助别人获得你们有过的机会。
Not just because you have an obligation to give something back to this country that has given our family so much--although you do have that obligation.
这并非只因国家给了我们一家这么多，你们也当有所回馈，虽然你们的确有这个义务，而是因为你们对自己负有义务。
But because you have an obligation to yourself. Because it is only when you hitch your wagon to something larger than yourself that you will realize your true potential.
因为，唯有在把你的马车套在更大的东西上时，你才会明白自己真正的潜能有多大。
These are the things I want for you--to grow up in a world with no limits on your dreams and no achievements beyond your reach, and to grow into compassionate, committed women who will help build that world.
这些是我想要让你们得到的东西：在一个梦想不受限制、无事不能成就的世界中长大，长成具慈悲心、坚持理想，能帮忙打造这样一个世界的女性。
And I want every child to have the same chances to learn and dream and grow and thrive that you girls have. That's why I've taken our family on this great adventure.
我要每个孩子都有和你们一样的机会，去学习、梦想、成长、发展。这就是我带领我们一家展开这趟大冒险的原因。
I am so proud of both of you. I love you more than you can ever know. And I am grateful every day for your patience, poise, grace, and humor as we prepare to start our new life together in the White House.
我深以你俩为荣，你们永远不会明白我有多爱你们，在我们准备一同在白宫开始新生活之际，我没有一天不为你们的忍耐、沉稳、明理和幽默而心存感激。
Love, Dad
爱你们的老爹
