河北省定州中学2016-2017学年高二（承智班）下学期英语周练试题（5-15）

百强校河北定州中学2016-2017学年第二学期高二承智班英语周练试题（5.15） 一、阅读理解 Does a 16-year-old have the ability to change the world, benefiting hundreds of thousands of people? Olivia Hallisey should believe so. With her invention of new Ebloa test, the girl from US has become the winner of the 2015 Google Science Fair, a yearly competition for creative teenagers who want to make a difference in the world. Hallisey’s method asks patients to put a sample of their saliva (唾液)onto a testing card. The card changes color if the person is infected with Ebloa. Present Ebloa tests can take up to 12 hours and cost $1,000. Hallisey’s method, by contrast, can be done just in 30 minutes for about $25. Moreover, the test needn’t be put in a refrigerator thanks to the silk material Olivia used to produce the testing cards. Hallisey started working on the test one year ago when she saw Ebloa spreading across African countries. Her research was based on looking at and using previous research and her own creative ideas.
