另外，国内有些地方的空气被人吐槽，是事实，但是美国的空气真的那么甜腻腻吗？今年4月，由美国肺科协会公布的《2017年空气状况调查报告》显示：全美10个空气最差的城市，加州就独占了8个，旧金山、湾区、奥克兰、洛杉矶无一幸免，加州有91%的居民生活在被污染的不健康空气下！

　　好吧，归根到底，我还是无法想象一个受过高等教育，具备独立的思考力和判断力的大学生，如何能说出对自己的故土进行全盘否定的话……

　　曾本科就读于马里兰大学，现在北京从事金融行业的Bob对此表示：“我觉得国人首先要有民族自豪感，自己先做到不卑不亢，才能让别人给你尊敬。女孩儿提到的问题诚然是一方面，我无法否认，但我们的国家也在一步步往好的方向在发展，当年英国还是雾都，美国也曾经历过黑人奴隶时代。每个国家，每一代人都有自己的问题，我们作为海外留学生，出国门就代表的是整个中国，能做的就是用自己的实际努力去make things better，一味的抱怨只会被别有用心的人拿来当枪使。”

　　下面我们来看看，什么才是留学生的正确演说方式：

　　👉 何江：哈佛大学生物系博士

　　去年作为优秀毕业生代表，在哈佛毕业典礼上致辞，凭借与众不同的理科视角和新颖的中国农村故事打动了哈佛学子，短短六七分钟的演讲，赢得了现场三万多人的掌声。

　　今年5月，在华盛顿大学的毕业典礼上，发表了毕业演讲辞。

　　演讲内容：

　　Thank you Grand Marshal Drobak. Thanks to everyone for this opportunity to speak today.

　　When I received the email to speak at Commencement, my first reaction was: “This must be a mistake.” I stared at the two-sentence message for at least three minutes. I assure you that, as a law student, I really can read faster than that. I was just amazed by the offer and the opportunity. Next, analyzing the situation as a good scientist and fledgling lawyer, I determined it was not April Fool’s Day. Accepting the fact that this must be real, a sudden and surprising surge of vanity took over, and I realized with horror that I just got braces on my teeth a few weeks ago. This might be my only opportunity to speak in front of such a large audience, and I might have chosen to put off the braces by a few weeks had I known. But, as my surprise and vanity subsided, I simply felt honored, and am so excited by this opportunity.

　　I called my parents in China, my husband in Washington, D.C., and my mother-in-law in South Korea, and asked: “Do you want to come to St. Louis for my Commencement? I will be speaking.” And, of course, they all said yes, and I am so happy they are here with me today.

　　I am, perhaps, not your typical graduate student. Before enrolling in law school at Washington University, I had already finished a PhD in chemical engineering, an MBA, two master’s degrees, and had worked for three years. I am much older than many of my peers, and have at least some “life experience.” It was not an easy decision for me to give up my engineering job, leave the career that I had been passionate about for more than 10 years, and return to school. But Washington University made this transition as easy as possible, and returning to earn a law degree has been one of the best decisions of my life. Why? Because Washington University gave me the kind of education that I had been craving for a long time.

　　A Washington University education is intellectually, mentally and physically challenging.

　　It is intellectually challenging because graduate and professional students work with faculty members to solve some of the hardest problems facing society today. Problems like converting and storing solar energy; altering proteins to create drugs that fight cancer; implementing programs to break the intergenerational cycle of diabetes; and developing strategies for preventing child abuse and partner violence.

　　This education is mentally and physically challenging as well. Students may have to handle caustic chemicals, endure sleep deprivation and overcome frustration. Reading 100 pages of Supreme Court opinions overnight in the library starts to feel like a “new normal.”

　　But rewards for meeting these challenges are great. This is the kind of education that is diverse and interdisciplinary. We are student entrepreneurs who work at Sling Health Network and collaborate with students from different backgrounds. We are McDonnell Scholars who live and work together to teach each other and become future leaders in a diverse and changing world. We are joint-degree students who intermingle academic disciplines to energize new pursuits and discoveries.

　　This is also an education that builds professional connections, mentorships and lifelong friendships. We worked as a team to polish deliverables for startup clients. We collaborated with faculty members, learning how to publish high-impact journal articles. We formed study groups to help each other through tough classes and research projects, and how to take our first steps as future teachers.

　　Ten years ago, when I first arrived in the United States, I had no idea that an opportunity like Washington University would be in my future. I’m so humbled to be surrounded by the most intelligent, energetic and knowledgeable colleagues and faculty members. Studying law for the past three years has not just taught me the statutes, legal theories and lawyering skills. It has also taught me how to prepare for the challenges the world outside academia will pose and, thanks to my education at Washington University, I will have the enthusiasm and confidence to move forward with determination.

　　Commencement speeches usually end with quotes by some famous people. When I tried to find these quotes, I remembered several from my closest mentor, which I am grateful to share with you: “Work hard. Be nice. No matter where you are heading in the future, I wish you all the luck in whatever life brings you.”

　　Thank you. Congratulations Class of 2017!
