年轻的美国以其开拓进取、勇于探索的精神向世人诠释了美利坚民族的优秀品质。下面的演讲节选自南希•佩罗西（美国历史上第一位众议院女议长）2007年在旧金山大学毕业典礼上的致辞，阐述了他在美国年轻一代身上找到了这种美国精神的特质，并寄予他们希望。

    The eternally young spirit of America has been a source or strength all of you bring forth today and has been a beacon of hope to the world. That optimism, faith, and confidence in our country, has made our country young.

    In my travels as Speaker, I have met with presidents, prime ministers, and kings. But what impressed and inspired me the most were my encounters with young people. At a time when some world leaders question the value of constructive dialogue with our adversaries, young people are engaged in their own international dialogue, on campuses and through email and instant messaging and blogs. They are talking about their hopes for a brighter future — of their desire for peace and prosperity …

    My message to the graduate today is : ” Know your power and follow your passion — the power and passion that springs from the beauty of your dreams, the depth of your imagination and the strength of your values.” I have confidence that you will succeed because of the magnificent education you have received. at USF. I want to extend my congratulations to the class of 2007, wish you well and let you know you have a friend in the Speaker’s office. Thank you and God bless you.

    美国永恒的青春气息是今天各位所展现出来的力量源泉，是这个世界希望的灯塔。美国的乐观、信仰和自信是她青春永驻。

    作为议长，我四处出访，会见过总统、总理、国王。但给我印象最深和最激励我的是我见到的那些年轻人。如今，当某些世界领导人在质疑与对立国之间建设性对话的价值的时候，年轻人就已经在校园里或通过电子邮件、即时短信和博客展开了他们自己的国际对话。他们谈论对辉煌未来的期望，对世界和平与繁荣的渴望……

    今天我献给毕业生的寄语是：“了解你的实力，追随你的激情——源自于梦想的美丽、想象的深度和价值观的力量。”我坚信，有了在旧金山大学接收到的良好教育，你们一定能够成功。祝贺2007届的毕业生，祝一切顺利。请记住你们在众议院有我这个朋友。谢谢你们。愿上帝保佑你们。
