A SPIDER’S BITE蜘蛛之咬
When I was in middle school, a poisonous spider bit my right hand. I ran to my mo m for help—but instead of taking me to a doctor, my mom set my hand on fire.
After wrapping my hand with several layers of cotton, then soaking it 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 burn - one minute, th en two minutes –until mom put out the fire.
You see, the part of China I grew up in was a rural village, and at that time pre-i ndustrial. When I was born, my village had no cars, no telephones, no electricity, not even running water. And we certainly didn’t have access to modern medical resour ces. There was no doctor my mother could bring me to see about my spider bite.
For those who study biology, you may have grasped the science behind my mom’s cure: heat deactivates proteins, and a spider’s venom is simply a form of protein. It’s cool how that folk remedy actually incorporates basic biochemistry, isn’t it? But I am a PhD student in biochemistry at Harvard, I now know that better, less painful and less risky treatments existed. So I can’t help but ask myself, why I didn’t rec eive one at the time?
Fifteen years have passed since that incident. I am happy to report that my hand i s fine. But this question lingers, and I continue to be troubled by the unequal distrib ution of scientific knowledge throughout the world. We have learned to edit the hum an genome and unlock many secrets of how cancer progresses. We can manipulate n euronal activity literally with the switch of a light. Each year brings more advances in biomedical research-exciting, transformative accomplishments. Yet, despite the knowl edge we have amassed, we haven’t been so successful in deploying it to where it’s needed most. According to the World Bank, twelve percent of the world’s populatio n lives on less than $2 a day. Malnutrition kills more than 3 million children annually. Three hundred million people are afflicted by malaria globally. All over the world, we constantly see these problems of poverty, illness, and lack of resources impeding the flow of scientific information. Lifesaving knowledge we take for granted in the moder n world is often unavailable in these underdeveloped regions. And in far too many pl aces, 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 sim ple, yet profound ways. The bird flu pandemic in the 2000s looked to my village like a spell cast by demons. Our folk medicine didn’t even have half-measures to offer. What’s more, farmers didn’t know the difference between common cold and flu; t hey didn’t understand that the flu was much more lethal than the common cold. Mo st people were also unaware that the virus could transmit across different species.
So when I realized that simple hygiene practices like separating different animal sp ecies could contain the spread of the disease, and that I could help make this knowl edge available to my village, that was my first “Aha”moment as a budding scientis t. But it was more than that: it was also a vital inflection point in my own ethical de velopment, my own self-understanding as a member of the global community.
Harvard dares us to dream big, to aspire to change the world. Here on this Com mencement Day, we are probably thinking of grand destinations and big adventures t hat await us. As for me, I am also thinking of the farmers in my village. My experien ce here reminds me how important it is for researchers to communicate our knowled ge to those who need it. Because by using the science we already have, we could pr obably bring my village and thousands like it into the world you and I take for grant ed every day. And that’s an impact every one of us can make!
But the question is, will we make the effort or not?
More than ever before, our society emphasizes science and innovation. But an eq ually important emphasis should be on distributing the knowledge we have to where it’s needed. Changing the world doesn’t mean that everyone has to find the next big thing. It can be as simple as becoming better communicators, and finding more c reative ways to pass on the knowledge we have to people like my mom and the far mers in their local community. Our society also needs to recognize that the equal dist ribution of knowledge is a pivotal step of human development, and work to bring this into reality.
And if we do that, then perhaps a teenager in rural China who is bitten by a spid er will not have to burn his hand, but will know to seek a doctor instead.

Thank you, thank you, President Faust, and Paul Choi, thank you so much. It`s an honor and a thrill to address this group of distinguished alumni and supportive friends and cavelling parents. We`ve all gathered to share in the joy of this day, so please join me in congratulating Harvard`s Class of 2016. I can remember my own college graduation, which is easy, since it was only 14 years ago. How many of you took 37 years to graduate? Because, like most of you, I began college in my teens, but sophomore year, I was offered my dream job at Universal Studios, so I dropped out. I told my parents if my movie career didn`t go well, I`d re-enroll.It went all right.But eventually, I returned for one big reason. Most people go to college for an education, and some go for their parents, but I went for my kids. I`m the father of seven, and I kept insisting on the importance of going to college, but I hadn`t walked the walk. So, in my fifties, I re-enrolled at Cal State -- Long Beach, and I earned my degree.I just have to add: It helped that they gave me course credit in paleontology for the work I did on Jurassic Park. That`s three units for Jurassic Park, thank you. Well I left college because I knew exactly what I wanted to do, and some of you know, too -- but some of you don`t. Or maybe

3分钟勇气英语演讲稿五篇 3分钟勇气英语演讲稿篇一 In the matter of courage we all have our limits. There never was a hero who did not have his bounds. I suppose it may be said of Nelson and all the others whose courage has been advertised that there came times in their lives when their bravery knew it had come to its limit. I have found mine a good many times. Sometimes this was expected--often it was unexpected. I know a man who is not afraid to sleep with a rattle-snake, but you could not get him to sleep with a safety-razor. I never had the courage to talk across a long, narrow room. I should be at the end of the room facing all the audience. If I attempt to talk across a room I find myself turning this way and that, and thus at alternate periods I have part of the audience behind me. You ought never to have any part of the audience behind you; you never can tell what they are going to do. I’ll sit down. 3分钟勇气英语演讲稿篇二 Ladies and gentlemen , good afternoon! i’m very glad to stand here and give you a short sp eech. today my topic is “youth”. i hope you will like it , and found the importance in your youth so that more cherish it. first i want to ask you some questions:
