(xx·无锡高三一模)When I was in middle school, a poisonous spider bit my right hand. I ran to my mom for __1__， but instead of taking me to a doctor, my mom set my hand __2__.
After wrapping my hand with several layers of cotton, then soaking it in wine, she put a chopstick into my mouth, and lit the cotton. Heat quickly went through the cotton and began to roast my __3__. The sharp pain made me want to scream, but the chopstick __4__ it. All I could do was watch my hand burn — one minute, then two minutes — __5__ Mom put out the fire.
At that time there was no doctor available my mother could bring me to see about my spider bite.
For those who study biology, you may have grasped the science __6__ my mom's cure: heat deactivates (使不活跃) proteins, and a spider's venom (毒液) is __7__ a form of protein. It's _
_8__ how that folk remedy actually includes basic biochemistry, isn't it? But I am a PhD student in biochemistry at Harvard. I now know that better, less __9__ and less risky treatments existed. So I can't help but ask myself why I didn't __10__ one at that time.
Now I am happy to report that my hand is fine. But this question remains, and I continue to be troubled by the unequal __11__ of scientific knowledge throughout the world. Despite the knowledge we have accumulated, we haven't been so __12__ in deploying (配置) it to where it's needed most. We constantly see these problems of poverty, illness, and  __13__ of resources preventing the flow of scientific information. Lifesaving knowledge we take for granted in the modern world is often __14__ in underdeveloped regions.
While studying at Harvard, I saw __15__ scientific knowledge can help others in simple, yet profound ways. The bird flu in the xxs looked to my village like a spell cast by devils. When I realized that simple hygiene (卫生) practices like __16__ different animal species could contain the spread of the disease, and that I could help make this knowledge available to my village, that was my first “Aha” moment as a budding scientist.
Harvard dares us to dream big, to aspire (立志) to change the world. Here on this mencement Day, we are __17__ thinking of grand destinations and big adventures that await us. As for me, I am also thinking of the farmers in my village. My experience here __18__ me how important it's for researchers to municate our knowledge to those __19__. Because by using the science we already have, we can probably bring my village and thousands like it into the world you and I take __20__ every day. And that's an impact every one of us can make!
