哈弗毕业典礼致辞哈弗毕业典礼致辞 哈弗毕业典礼致辞 蜘蛛轶事 何江 当我在上中学的时候，一次被一只有毒的蜘蛛咬了一 口，我哭着跑向母亲求助。然而母亲并没有领着我去看医 生，相反，她点燃了我的手。她将我的手用浸过白酒的棉 布摩擦包扎之后，在我的嘴巴里塞进一支筷子让我咬着， 然后就点着了棉布。 热量快速地穿过棉布直击我的皮肤，烘烤着我的手背。 这种撕心裂肺的疼痛让我想要尖叫，但是却叫不出声，因 为嘴里还咬着筷子。我所能做的只有盯着我的手看，一分 钟，两分钟，直到母亲吹灭了火。 你可以看出我所成长的地方，一个中国的小村庄，在 那个时候，还未工业化。当我出生的时候，我的村庄里还 没有汽车，没有电话，没有电力，甚至没有自来水，更不 用提现代化的医疗资源。在那里没有母亲可以领着我去看 我被蜘蛛咬伤的伤口的医生。 对于那些学习生物的学生，你们或许已经看出来了我 母亲这种民间疗法的科学依据：热量使蛋白质失活，而蜘 蛛的毒液充斥着蛋白质。很厉害吧?这种民间疗法怎么会和 现代科学这么契合，不是吗?但作为一个哈佛生物化学方向 的博士生，我现在知道了一个更好的、疼痛更少、风险更 小的疗法。 所以，我不禁问我自己，为什么我那个时候没有得到 这样的治疗呢?这件事已经过去 15 年了，我可以很开心地 向你们报告，我的手完好无损。但是那个问题依旧萦绕在 我的脑海里，科学知识在世界上不均衡分布的问题也持续 困扰着我。 我们学会了编辑人类的基因谱，揭示了许多有关癌症 的秘密，我们可以轻易操纵神经元的活动，每年我们在生 物化学领域都有着无数进步和成就。然而，我们却没有成 功地将这些我们已有的知识传递给那些最需要它们的地方。 每年有 12%的人口每天仅靠不足 2 美元生活，每年有 300 万儿童死于营养不良，全球有 3 亿人受到疟疾的侵扰。 我们持续地看到贫困、疾病，和资源匮乏阻碍着科学的传 播。那些我们习以为常，救人于水火之中的知识在那些欠 发达地区非常匮乏，所以直至今日都还有人用火烧来治疗 被蜘蛛咬下的伤口。 当我在哈佛学习时，我彻底明白了科学知识是怎样以 一种简单却深刻的方式帮助他人的。XX 年流感暴发，我的 故乡像被魔鬼下了咒语一样一蹶不振，民间医术根本难以 找到治疗方法。农民们不知道流感与普通感冒的差别，他 们更不知道流感远远比普通感冒致死率高，他们中的绝大 多数人不了解病毒是可以在牲畜之间传播的。 所以当我第一次了解到简单的卫生操作，比如隔离不 同的牲畜可以帮助限制疾病，能够帮助我的故乡更便捷地 获得这类知识的时候，我对我所从事行业的职业观念的理 解有了一次重大转折，这也改变了我作为地球村一员的自 我理解。 哈佛鼓励我们去梦想，去渴望，去改变世界。今天在 毕业典礼上，我们是应该去考虑宏伟的目标，但对我来说， 我也关心我故乡的村民们。 我的经历提醒着我，研究者们传递自己的知识给需要 的人有多么重要。有了科学，我们可以将成千上万像我故 乡一样的地区拉进这个我们已经习以为常的世界，这，是 我们每个人都可以做的一件事。但问题是，我们是否愿意 为此努力? 改变世界不代表每个人都要去发现什么伟大的东西， 简单地成为一个传递者，把我们已有的知识带给这个地球 村里无数像我母亲一样的人，就已经很好。 我们的社会应该消灭知识鸿沟，这是人类进步不可或 缺的一步，需要我们来实现。如果我们行动了，兴许再有 来自中国偏远地区的小男孩，当他被蜘蛛咬的时候，他会 知道去看医生，而不是用火烧他的手。 谢谢! Commencement Speechby JIANG HE When I was in middle school, a poisonous spider bit my right hand. I ran to my mom for help, but instead of taking to a doctor, my Mom set my hand on fire. After rubbing my hand with several mares of cotton then soaked in wine,she put a chopstick into my mouth and ignited the cotton。 Heat quickly penetrated the cotton and began to roast my hand. The searing pain made me want to scream but the chopstick prevented it. All I could do was watch my hand bone, one minute, then two minutes, until my mom put off the fire。 You see the Public China I grew up in was a rural village, and at that time, pre industrial. When I was born, my village had no cars, no telephones, no electricity, not even running water and we certainly didnt had access to the modern medical resources。 There was no doctor my mother could bring me to see about this spider bite. For those who study Biology, you may have brought the science behind my moms cure: heat deactivates proteins and the spider venom is full of protein. Its cool how could this folk remedy incorporate with the base of biochemistry, isnt it? But I am a student in Biochemistry study at Harvard, I now know a better, less painful and less risky treatment existed. So, I cant help but ask myself, why I didt receive one at that time? Fifteen years have passed since that incident, I am happy to report that my hand is fine. But this question lingers and I continued to be troubled by the unequal distribution of scientific knowledge throughout the world。 We have learn to edit the human geneal and uncover many secrets of how cancer progressing. We can manipulate neuron activity literally with the switch of light. Each year with more advances in Biomedical research, exciting transformative accomplishment。 Yet despite the knowledge we had on that, we havent be so successful deploying it to where need it most. According to the World Bank, 12% of world population lives on less than 2 dollars a day。 Malnutrition kills more than 3 millions children annually. Three hundred million people are afflicted by Malaria globally. All over the world, we constantly see the problem of poverty, illness and lack of resources impeding the flow scientific information。 Life-saving knowledge took for granted in our modern world is over-unavailable in the underdeveloped regions. And so, in far to many places, people are still essentially trying to cure a spider bite with fire。 While studying at Harvard, I saw how scientific knowledge can help others in simple, in profound ways. The burst through pandemic in XX took my village like a spell cast by demons。 Our folk medicine didnt even have half- mattress offer. Whats more, farmers did not know the difference between the common cold and flu. They did not understand that the flu is much more lethal than common cold. Most of all are also unaware that the virus are transmitted by animal species。 So when I realize that simple hygiene practices like separate different animal species could help contain this kind of disease and that I could help this kind of knowledge available to my village。 That was my first “aha“ moment as a bioscientist. But it was more than that: it was also a vital inflection point of my own ethical development, my own self-understanding as a member of global community。 Harvard dares us to dream big, to aspire, to change the world. Here on this Commencement Day, we are appropriate the thinking of grand destination that wait us 。 As for me, I am also thinking of the farmers in my village. My experience here reminds me how important it is for researchers to communicate our knowledges, to those who need it. Because by using the science we already have, we can proper my village and thousands like it into the world you and I take for granted every day and thats an impact every one of us can made。 But the question is, will we make the effort , or not? More than ever before, our society emphasized our science and innovation, but an equally important emphasis should on distributing the knowledge we ha
