【題目】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 (樣本) 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.”

【1】According to the passage, present Ebola detection methods ______.

A. must use a large amount of samples

B. may detect other deadly viruses as well

C. have proven to be ineffective in practice

D. require samples to be kept in refrigerators

【2】What can we learn about Olivia’s method?

A. Time-consuming. B. Cheap.

C. Complex. D. Out-of-date.

【3】What does the underlined word “drawn” in Paragraph 5 probably mean？

C. Admitted. D. Exposed.

【4】The Google Science Fair is intended for ______.
