In line with the promise of this age, I want to exhort each of the graduates here to take on an issue - a complex problem, a deep inequity, and become a specialist on it. If you make it the focus of your career, that would be phenomenal. But you don't have to do that to make an impact. For a few hours every week, you can use the growing power of the Internet to get informed, find others with the same interests, see the barriers, and find ways to cut through them.

　　同這個時代的期望一樣，我也要向今天各位畢業(yè)的同學提出一個忠告：你們要選擇一個問題，一個復雜的問題，一個有關于人類深刻的不平等的問題，然后你們要變成這個問題的專家。如果你們能夠使得這個問題成為你們職業(yè)的核心，那么你們就會非常杰出。但是，你們不必一定要去做那些大事。每個星期只用幾個小時，你就可以通過互聯(lián)網得到信息，找到志同道合的朋友，發(fā)現(xiàn)困難所在，找到解決它們的途徑。

　　Don't let complexity stop you. Be activists. Take on the big inequities. It will be one of the great experiences of your lives.

　　不要讓這個世界的復雜性阻礙你前進。要成為一個行動主義者。將解決人類的不平等視為己任。它將成為你生命中最重要的經歷之一。

　　You graduates are coming of age in an amazing time. As you leave Harvard, you have technology that members of my class never had. You have awareness of global inequity, which we did not have. And with that awareness, you likely also have an informed conscience that will torment you if you abandon these people whose lives you could change with very little effort. You have more than we had; you must start sooner, and carry on longer.

　　在座的各位畢業(yè)的同學，你們所處的時代是一個神奇的時代。當你們離開哈佛的時候，你們擁有的技術，是我們那一屆學生所沒有的。你們已經了解到了世界上的不平等，我們那時還不知道這些。有了這樣的了解之后，要是你再棄那些你可以幫助的人們于不顧，就將受到良心的譴責，只需一點小小的努力，你就可以改變那些人們的生活。你們比我們擁有更大的能力;你們必須盡早開始，盡可能長時期堅持下去。

　　Knowing what you know, how could you not?

　　知道了你們所知道的一切，你們怎么可能不采取行動呢?

　　And I hope you will come back here to Harvard 30 years from now and reflect on what you have done with your talent and your energy. I hope you will judge yourselves not on your professional accomplishments alone, but also on how well you have addressed the world's deepest inequities ... on how well you treated people a world away who have nothing in common with you but their humanity.

　　我希望，30年后你們還會再回到哈佛，想起你們用自己的天賦和能力所做出的一切。我希望，在那個時候，你們用來評價自己的標準，不僅僅是你們的專業(yè)成就，而包括你們?yōu)楦淖冞@個世界深刻的不平等所做出的努力，以及你們如何善待那些遠隔千山萬水、與你們毫不涉及的人們，你們與他們唯一的共同點就是同為人類。

　　Good luck.

　　最后，祝各位同學好運。
