Question

【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.”

【4】 A

【解析】

本文是一篇說明文。文章介紹了一名青少年發(fā)明家。正是因?yàn)檫@名來自Connecticut的少年，世界距離快速廉價(jià)的Ebola檢測又近了一步。

【1】推理判斷題。根據(jù)第二段中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.可知，根據(jù)文章，目前的Ebola檢測方法要求樣本保存在冰箱中。故選D。

【2】推理判斷題。根據(jù)第二段中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.可知，我們從Olivia的方法中得知它是“便宜的”。故選B。

【3】詞義猜測題。根據(jù)最后一段中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. 我只是想鼓勵(lì)女孩們?cè)谝婚_始就嘗試一下，并提醒她們不必覺得自己天生就有吸引力，也不必覺得自己在數(shù)學(xué)或科學(xué)方面有什么特別的天賦。由此推知?jiǎng)澗�詞的意思是“吸引”。故選A。

【4】推理判斷題。根據(jù)第二段第一句Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola,可知，The Google Science Fair是為學(xué)生準(zhǔn)備的。故選A。

任何一篇文章中的句子在內(nèi)容上都不是絕對(duì)孤立的，都跟句子所在的段落及整整篇文章有關(guān)。利用上下文提供的情景和線索，進(jìn)行合乎邏輯的綜合分析進(jìn)而推測詞義，尤其是要注意劃線詞前后的內(nèi)容。本文第3小題，根據(jù)最后一段中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. 我只是想鼓勵(lì)女孩們?cè)谝婚_始就嘗試一下，并提醒她們不必覺得自己天生就有吸引力，也不必覺得自己在數(shù)學(xué)或科學(xué)方面有什么特別的天賦。由此推知?jiǎng)澗�詞的意思是“吸引”。故選A。
