你也是个很好的姐姐。虽然你们姐妹以前也会打架，但是长大后，你们真的成为了好朋友。妹妹很爱你，很喜欢逗你笑，她把你当成她的榜样看待。我们开车离开哥大后，她非常想你，我知道你也很想她。世界上最宝贵的就是家人。和父母一样，妹妹就是你最可以信任的人。随着年龄的增长，你们姐妹之间的情谊不变，你们互相照应，彼此关心，这就是我最希望见到的事情了。在你的大学四年，有空时你一定要常常跟妹妹视频聊聊天，写写电子邮件。

You have been an excellent elder sister. Even though you twohadyour share of fights, the last few years you have becomebestfriends. Your sister loves you so much, and she loves to makeyoulaugh. She looks up to you, and sees you as her role model. Asyousaw when we departed, she misses you so much. And I know thatyoumiss her just as much. There is nothing like family, and otherthanyour parents, your sister is the one person who you can trustandconfide in. She will be the one to take care of you, and theoneyou must take care of. There is nothing we wish more than thatyoursisterhood will continue to bond as you grow older, and thatyouwill take care of each other throughout your lives. For thenextfour years, do have a short video chat with her every few days,anddo email her when you have a chance.

大学将是你人生最重要的时光，在大学里你会发现学习的真谛。你以前经常会问到“这个课程有什么用”，这是个好问题，但是我希望你理解：“教育的真谛就是当你忘记一切所学到的东西之后所剩下的东西。”我的意思是，最重要的不是你学到的具体的知识，而是你学习新事物和解决新问题的能力。这才是大学学习的真正意义——这将是你从被动学习转向自主学习的阶段，之后你会变成一个很好的自学者。所以，即便你所学的不是生活里所急需的，也要认真看待大学里的每一门功课，就算学习的技能你会忘记，学习的能力是你将受用终身的。

College will be the most important years in your life. It isincollege that you will truly discover what learning is about.Youoften question “what good is this course”. I encourage you tobeinquisitive, but I also want to tell you : “education is whatyouhave left after all that is taught is forgotten”. What I meanbythat is the materials taught isn’t as important as you gainingtheability to learn a new subject, and the ability to analyze anewproblem. That is really what learning in college is about –thiswill be the period where you go from teacher-taughttomaster-inspired, after which you must become self-learner. Sodotake each subject seriously, and even if what you learnisn’tcritical for your life, the skills of learning will besomethingyou cherish forever.

不要被教条所束缚，任何问题都没有一个唯一的简单的答案。还记得当我帮助你高中的辩论课程时，我总是让你站在你不认可的那一方来辩论吗？我这么做的理由就是希望你能够理解：看待一个问题不应该非黑即白，而是有很多方法和角度。当你意识到这点的时候，你就会成为一个很好的解决问题者。这就是“批判的思维”——你的一生都会需要的最重要的思考方式，这也意味着你还需要包容和支持不同于你的其他观点。我永远记得我去找我的博士导师提出了一个新论题，他告诉我：“我不同意你，但我支持你。”多年后，我认识到这不仅仅是包容，而是一种批判式思考，更是令人折服的领导风格，现在这也变成了我的一部分。我希望这也能成为你的一部分。
