Section Ⅰ　Reading and Thinking（1） 阅读理解 A 　　（2025·宁德高二上第三次阶段测试）Charles Richard Drew’s great invention directly contributed to saving thousands of lives during World WarⅡ， and continues to contribute to the life-saving work of the entire world of medicine later. 　　Born in 1904， Drew was the eldest of five children.He was intelligent and showed a talent for studies and sports from a young age.In 1922， his athletic ability earned him an athletic scholarship to attend Amherst College in Massachusetts.Drew graduated from Amherst College in 1926.In 1928， he applied to medical schools and was admitted to McGill University in Montreal， Canada.He completed his medical degree and master’s degree in surgery in 1933. 　　Upon graduation， as an internship （实习生）， he began to look at issues related to blood transfusions. 　　When he began his doctoral studies at Columbia University， with a physician named John Scudder， Drew continued his research in the field of blood transfusion.The two had jointly conducted research into blood preservation and fluid replacement， leading to the development of an experimental blood bank， which ran smoothly for seven months. 　　Drew’s breakthroughs in blood preservation were timely， as the World War Ⅱ was raging in Europe at the time.Under Drew’s direction， his team developed new ways to extract， preserve and transport plasma （血浆） on a large scale. 　　Following the success of the “Blood for Britain” program， Drew was appointed the assistant director for the US blood banking system.During this time， he built a number of mobile blood donation stations， later known as blood delivery stations. 　　On 1 April 1950， tragedy struck.Drew was injured in a serious car accident while on his way to a conference and died from his injuries.Many medical colleges and schools have been named after him to honor his contribution. 1.What is the second paragraph mainly about？（　　） A.Charles Richard Drew’s family. B.Charles Richard Drew’s intelligence. C.Charles Richard Drew’s early experience. D.Charles Richard Drew’s contribution. 2.What kind of person is Charles Richard Drew？（　　） A.Strong-willed and ambitious. B.Sympathetic and tough. C.Caring and brave. D.Talented and committed. 3.Why are many colleges and schools named after Charles Richard Drew？（　　） A.Because he has made a great contribution to medical science. B.Because he alone finished the research in the field of blood transfusion. C.Because his contribution has changed the process of the World War Ⅱ. D.Because he died in a tragic car accident on his way to a conference. 4.Which category can this article be？（　　） A.A documentary. B.A novel. C.A science fiction. D.A short biography. B 　　（2025·吉林八校高二上期末）Someday， shadows and light could team up to provide power.A new device uses the contrast （差异） between bright spots and shade to create an electric current.That current can power small electronics， such as a watch or LED lights. 　　Swee Ching Tan and his team call their new device a shadow-effect energy generator.They made it by coating silicon （硅） with a thin layer of gold.Silicon is often used in solar cells that produce electricity from sunlight. 　　As in a solar cell， light shining on this generator energizes electrons （电子） in the silicon.Those electrons then jump into the gold.The difference in light levels creates an electric current.Sending electrons makes a flow of current that can power small electronics. 　　Tan’s team described the new device in Energy & Environmental Science.Each device measures 4 cm long and 2 cm wide.That makes its area slightly larger than a stamp.In low light， eight generators power an electronic watch.These devices can also serve as self-powered motion sensors （传感器）.For instance， when a toy car passed by， its shadow fell on a generator.That created enough electricity to light an LED. 　　The team compared its generators to commercial solar cells that are typically used under full sunlight.With half of each device in shadow， the generators produced roughly twice as much power per surface area as the solar cells.“But it would be better to compare them to solar cells meant to work in low light， such as the silicon solar cells in classroom calculators.These are designed to use indoor light，” said Emily Warren， a chemical engineer at the National Renewable Energy Laboratory.Warren also would like to see the team measure the power the devices make over a longer time， such as a whole day. 　　Increasing how much light the generators can absorb would allow them to make better use of shadows.So the team is working to improve the device’s performance with strategies that solar cells use to gather light. 5.What is the outer layer of Tan’s energy generator？（　　） A.Gold. B.Silicon. C.A solar cell. D.An LED light. 6.What was Emily Warren’s attitude toward Tan’s new device？（　　） A.Doubtful. B.Objective. C.Conservative. D.Expectant. 7.Which aspect of the device is the team working on at present？（　　） A.Its better use of solar cells. B.Its means of locating shadows. C.Its efficiency in light absorbing. D.Its application to the households. 8.What is the best title for the text？（　　） A.Renewable Energy Usage on the Rise B.Shadow Effect Can Produce Electricity C.A New Device to Harvest Solar Energy D.Shadow Energy May Replace Solar Energy 2 / 2 学科网（北京）股份有限公司 $ 课时跟踪检测部分 UNIT 1　SCIENCE AND SCIENTISTS Section Ⅰ　Reading and Thinking（1） 语篇解读：本文是一篇说明文。文章主要介绍了Charles Richard Drew的早期经历和他在血液保存、输血等医学方面所取得的成就以及做出的伟大贡献。 1.C　段落大意题。根据第二段所提到的时间及全段内容可知，该段主要讲述了Charles Richard Drew的早期经历。 2.D　推理判断题。根据全文内容可知，Charles Richard Drew非常有才华，一直致力于血液保存、输血等医学方面的研究，并取得了伟大的成就。 3.A　细节理解题。根据最后一段最后一句可知，Charles Richard Drew在医学方面做出了巨大贡献，所以许多医学院都以他的名字命名，来纪念他的贡献。 4.D　推理判断题。本文描述了Charles Richard Drew的传奇一生以及他对医学的贡献，因而本文是一篇传记。 语篇解读：本文是一篇说明文。文章主要介绍了科学家研发的一种新装置，这种装置可以利用明亮的点和阴影之间的差异发电。 5.A　细节理解题。根据第二段中的They made it by coating silicon （硅） with a thin layer of gold.可知，Tan的能量发生器最外层是一层黄金。 6.D　推理判断题。根据倒数第二段最后一句可知，Emily Warren对新设备有所期待。 7.C　细节理解题。根据最后一段内容可知，团队目前的工作重点在于提高该设备吸收光线的表现和效率。 8.B　标题归纳题。本文主要介绍了科学家研发的一种新装置，这种装置可以利用明亮的点和阴影之间的差异发电。B项（阴影效应能发电）可作文章最佳标题。 2 / 2 学科网（北京）股份有限公司 $
