【题目】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 (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.”
【1】According to the passage, present Ebola detection methods ______.
A. must use a large amount of samples

【3】What does the underlined word “drawn” in Paragraph 5 probably mean?
A. Attracted. B. Controlled.
C. Admitted. D. Exposed.
【4】The Google Science Fair is intended for ______.
A. students B. doctors
C. inventors D. scientists
【答案】
【1】 D
【2】 B
【3】 A
【4】 A
【解析】
本文是一篇说明文。文章介绍了一名青少年发明家。正是因为这名来自Connecticut的少年,世界距离快速廉价的Ebola检测又近了一步。
【1】推理判断题。根据第二段中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 (样本) doesn’t have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.可知,根据文章,目前的Ebola检测方法要求样本保存在冰箱中。故选D。
【2】推理判断题。根据第二段中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,我们从Olivia的方法中得知它是“便宜的”。故选B。
【3】词义猜测题。根据最后一段中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. 我只是想鼓励女孩们在一开始就尝试一下,并提醒她们不必觉得自己天生就有吸引力,也不必觉得自己在数学或科学方面有什么特别的天赋。由此推知划线词的意思是“吸引”。故选A。
【4】推理判断题。根据第二段第一句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是为学生准备的。故选A。
任何一篇文章中的句子在内容上都不是绝对孤立的,都跟句子所在的段落及整整篇文章有关。利用上下文提供的情景和线索,进行合乎逻辑的综合分析进而推测词义,尤其是要注意划线词前后的内容。本文第3小题,根据最后一段中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. 我只是想鼓励女孩们在一开始就尝试一下,并提醒她们不必觉得自己天生就有吸引力,也不必觉得自己在数学或科学方面有什么特别的天赋。由此推知划线词的意思是“吸引”。故选A。
