A Teenage Inventor

The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia’s method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia’s method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn’t have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

“What affects one country affects everyone,”Olivia told CNBC. “We have to work together to find answers to the huge challenges which cause harm to the global health.” The Connecticut’s teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

Olivia hopes her success will inspire other girls interested in science and computers. “I would just encourage girls to try it in the beginning, and remind them that they don’t have to feel naturally drawn or feel like they have a special talent for maths or science,” she told CNBC, “but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests.”

I was born with eye disease. At school I even couldn’t read the blackboard. By the time I got to university, I couldn’t really see images(图像) at all. I just can tell the difference between light and dark. In the first year of my PHD, I was almost 100% blind.

When I was young I used to get very angry if I encountered something I found difficult or couldn’t do because of my eyes. But over time I learned that wasn’t a helpful response. There’s no point getting wound up by the fact that I can’t see, because it won’t change it.

I started climbing when I was young. My dad took me up my first rock route(路线) when I was two. All my early climbing was outdoor traditional climbing. My dad had been in the Mountain Rescue and was part of Mountaineering Club, so we would go for weekends away climbing throughout the UK.

He taught me everything I know and I led my first route outside when I was 11. At this time I could just about see well enough to place rock gear(齿轮), but not well enough to pick out the routes from the ground. People are usually amazed when they discover that not only do I climb, but I also lead climbs.

At university I joined the Mountaineering Club and was able to climb much more frequently. We had regular trips to indoor walls and weekends away outdoors. I developed a great circle of climbing friends and went on multiple trips to Europe. On these I started Alpine climbing and ice climbing too.

There was a time when I thought I might have to give up leading as my eyesight got worse. But I never thought I would stop climbing. I just learnt to adapt myself to the eye disease with the support of my friends. It’s quite possible that I wouldn’t be as good a climber if I weren’t blind — if I didn’t have these challenges. That concentration and determination is built through my disability.

【小题3】What does the author believe contributed to his success in climbing?
A.His disability.B.His university.

【小题4】Which of the following can be the best title?
A.A Blind Man’s Life Struggle.B.Mountain Climbing Experience.
