But Shanya Gill, a middle schooler from San Jose, California, won the top award in the Thermo Fisher Scientific Junior Innovators Challenge for designing a fire detection system that is superior to existing ones, as stated in the press release.“The top winners have exhibited boundless curiosity,” Maya Ajmera president and CEO of Society for Science, said in the press release. “Their remarkable research not only reflects their talent but also paves the way for an exciting new future.”Shanyas inspiration came after a fire destroyed a restaurant in her neighborhood during the summer of 2022, reported The Washington Post. “I had never really experienced something like that before,” she told The Washington Post about the early morning fire at Holders Country Inn, which started in the kitchen. “They had smoke detectors and yet it still burned down,” she added.After she studied fire statistics, Shaya spent over a year developing a fire detection system that she believes could have prevented the fire. Unlike traditional smoke detectors that sense active fires from the smoke in the air, Shanyas thermal (热的) imaging device is designed to stop fires from occurring.With a thermal camera and a Raspberry Pi, a tiny computer the device detects when a heat source has been left unattended for ten minutes and sends a text message warning. Creating the prototype(原型) was difficult and the hardest part was the programming, “I had two designs, and my first design completely failed. It was a really big challenge I had to go through.” she said. The final device outperforms smoke detectors in speed and accuracy. Shanya wants to bring the costs down to make it even more common than hardwired smoke detectors.“Shanya saw a problem, went after it and tried to solve it, and thats what we need to encourage with all young people,” said Ajmera. She also highlighted the significance of supporting individuals, especially girls and kids of color, in STEM fields, as research indicates that many young people drop out of these areas.24.What can we learn about Shanya from the first two paragraphs?A. She gained a lot of money in the award.B. She showed a curious nature as a schooler.C. She set a big stage for young people her age.D. She was junior to other winners in performance.25.What motivated Shanya to develop her fire detection system?A. Her desire to win the science award.B. Her experience of a destructive fire.C. Her interest in computer programming.D. Her goal to improve STEM education for girls.26.What is an advantage of Shanyas invention?A. It consists of two parts that are easier to conduct.B. It can send out a warning against a potential fire.C. It can detect active fires from the smoke in the air.D. It functions when a fire breaks out within 10 minutes.27.Which of the following can best describe Shanya?A. Reliable. B. Cooperative. C. Innovative. D. Generous.【导语】这是一篇说明文。文章主要说明了来自加州圣何塞的中学生Shanya Gill在赛默飞世尔科学少年创新者挑战赛中获得了最高奖项，因为她设计了一种优于现有系统的火灾探测系统。文章介绍了这种系统开发背后的灵感来源以及优点。1.B 细节理解题。根据第二段“The top winners have exhibited boundless curiosity,” Maya Ajmera president and CEO of Society for Science, said in the press release. (科学学会主席兼首席执行官玛雅阿杰梅拉在新闻发布会上说：“顶级获奖者表现出了无限的好奇心。”)”可知，Shanya表现出学者好奇的天性。故选B。2.B 细节理解题。根据第三段“Shanyas inspiration came after a fire destroyed a restaurant in her neighborhood during the summer of 2022, reported The Washington Post. (据华盛顿邮报报道，Shanya的灵感来自于2022年夏天一场大火烧毁了她家附近的一家餐馆)”可知，经历了一场毁灭性的火灾促使Shanya开发她的火灾探测系统。故选B。3.A 细节理解题。根据倒数第二段“With a thermal camera and a tiny computer, the device detects when a heat source has been left unattended for ten minutes and sends a text message warning. (该设备配备了一个热像仪和一台微型电脑，当热源无人看管超过10分钟时，它就会检测到，并发出短信警告。)”可知，Shanya的发明优点在于可以发出潜在火灾的警告。故选A。提问：七选五 （难度：较易）The Spotlight EffectHave you ever felt as if the entire world was watching while you made a mistake? Well, heres some good news: its likely that no one even noticed. 36 We have this experience not only when we make mistakes but also when we perform well. Every time we do something that is a little different from what we usually do, we may assume that everyone around us will notice. The spotlight effect might happen when we make a mistake in a game, have a bad hair day, or give a terrible answer in class. 37 In these moments, it feels like everyone is watching.The spotlight effect exists because we all get used to seeing things through our own eyes. Every person is the main character in his or her story,
