The 2023 Thermo Fisher JIC competition showcased this spirit. Thirty finalists presented creative 1 to global issues, from environmental pollution to public health challenges. One standout participant was 14-year-old Amritha Praveen from Illinois. She built a system that uses people’s 2 to music to recommend songs that put them at ease. Her goal is to improve the 3 of music on mental health. Amritha’s system uses sensors to 4 someone’s heart rate while listening to music. Then, the system uses that information to recommend other music that is likely to help the person 5 . Amritha’s 6 came from her lifelong passion for music. She noticed how different music types caused 7 emotional reactions as a violin player. This 8 drove her to seek an objective method to measure the relaxation when listening to different types of music. Her research found two key factors leading to relaxation: musical key and timbre (音色) — the latter being a(n) 9 discovery. “Timbre’s role surprised me,” she admitted. “It refers to the tone color of sound.” Looking ahead, Amritha plans to 10 her project by studying how different types of instruments affect bodily responses and using brain waves to 11 how people respond to music. “Understanding the brain’s role could 12 why music moves us,” she said. The 13 not only awarded prizes but also proved that young innovators can turn   14 into tool for social good. As Amritha’s work demonstrates, scientific curiosity 15 compassion (同理心) can truly make a difference. 1．A．introductions B．solutions C．guides D．plans 2．A．devotion B．access C．response D．attitude 3．A．effectiveness B．quality C．popularity D．richness 4．A．match B．increase C．control D．measure 5．A．focus B．sing C．recover D．relax 6．A．inspiration B．hesitation C．limitation D．illustration 7．A．similar B．violent C．chemical D．varied 8．A．observation B．moment C．occasion D．position 9．A．small B．unexpected C．reliable D．precious 10．A．simplify B．expand C．stop D．publish 11．A．guess B．question C．compare D．track 12．A．explain B．challenge C．imagine D．change 13．A．program B．experience C．competition D．system 14．A．skills B．hobbies C．materials D．data 15．A．compared to B．resulted in C．paired with D．absorbed in 【答案】 1．B 2．C 3．A 4．D 5．D 6．A 7．D 8．A 9．B 10．B 11．D 12．A 13．C 14．B 15．C 【导语】本文是一篇说明文。主要介绍了在2023年赛默飞世尔JIC竞赛中，14岁的Amritha Praveen通过自己的科学项目展示了年轻人如何将科学好奇心与同理心相结合，为解决现实世界问题做出贡献。 1．考查名词词义辨析。句意：三十位决赛选手展示了针对全球问题的创造性解决方案，从环境污染到公共卫生挑战。A. introductions介绍；B. solutions解决方案；C. guides指南；D. plans计划。根据前文“science projects are not just assignments but opportunities to solve real-world problems”可知，科学项目是解决现实世界问题的机会，所以这里三十位决赛选手展示的应是针对全球问题的创造性“解决方案”。故选B项。 2．考查名词词义辨析。句意：她建立了一个系统，利用人们对音乐的反应来推荐能让他们放松的歌曲。A. devotion奉献；B. access通道；C. response反应；D. attitude态度。根据后文“to recommend songs that put them at ease”和“Amritha’s system uses sensors to ___4___ someone’s heart rate while listening to music.”以及“Her research found two key factors leading to relaxation”可知，该系统是依据某些因素，通过监测心率来了解人们对音乐的“反应”来进行歌曲推荐的。故选C项。 3．考查名词词义辨析。句意：她的目标是提高音乐对心理健康的有效性。A. effectiveness有效性；B. quality质量；C. popularity流行度；D. richness丰富性。根据前文“to recommend songs that put them at ease”可知，她建立系统推荐歌曲是为了让人们放松，由此可推知，她的目标是提高音乐对心理健康的“有效性”。故选A项。 4．考查动词词义辨析。句意：Amritha的系统使用传感器来测量某人听音乐时的心率。A. match匹配；B. increase增加；C. control控制；D. measure测量。根据后文“someone’s heart rate while listening to music”以及“the system uses that information”可知，系统要利用心率信息，所以应是使用传感器来“测量”心率。故选D项。 5．考查动词词义辨析。句意：然后，系统利用这些信息推荐其他可能有助于此人放松的音乐。A. focus集中；B. sing唱歌；C. recover恢复；D. relax放松。根据前文“to recommend songs that put them at ease”可知，推荐歌曲的目的是让人放松，所以此处应是推荐有助于此人“放松”的音乐。故选D项。 6．考查名词词义辨析。句意：Amritha的灵感来自她毕生对音乐的热爱。A. inspiration灵感；B. hesitation犹豫；C. limitation限制；D. illustration说明。根据后文“came from her lifelong passion for music”可知，她对音乐有终生的热爱，这是她项目的“灵感”来源。故选A项。 7．考查形容词词义辨析。句意：作为一名小提琴手，她注意到不同类型的音乐会引起不同的情绪反应。A. similar相似的；B. violent暴力的；C. chemical化学的；D. varied各种各样的，不同的。根据前文“She noticed how different music types”以及后文“drove her to seek an objective method to measure the relaxation when listening to different types of music”可知，不同类型的音乐会引起“不同的”情绪反应，所以她才会寻求测量不同类型音乐放松程度的方法。故选D项。 8．考查名词词义辨析。句意：这一观察促使她寻求一种客观的方法来测量听不同类型音乐时的放松程度。A. observation观察；B. moment时刻；C. occasion场合；D. position位置。根据前文“She noticed how different music types caused ___7___ emotional reactions as a violin player.”可知，她注意到不同类型的音乐会引起不同的情绪反应，这是她的“观察”，正是这一观察促使她寻求测量方法。故选A项。 9．考查形容词词义辨析。句意：她的研究发现，导致放松的两个关键因素是音调和音色——后者是一个意想不到的发现。A. small小的；B. unexpected意想不到的；C. reliable可靠的；D. precious珍贵的。根据后文“Timbre’s role surprised me”可知，音色所起的作用让她感到惊讶，所以这是一个“意想不到的”发现。故选B项。 10．考查动词词义辨析。句意：展望未来，Amritha计划通过研究不同类型的乐器如何影响身体反应，并使用脑电波来追踪人们对音乐的反应，来扩展她的项目。A. simplify简化；B. expand扩展；C. stop停止；D. publish出版。根据后文“by studying how different types of instruments affect bodily responses and using brain waves to ___11___ how people respond to music”可知，她计划通过研究不同类型乐器对身体反应的影响以及使用脑电波追踪人们对音乐的反应来进一步开展工作，所以是“扩展”她的项目。故选B项。 11．考查动词词义辨析。句意：同上。A. guess猜测；B. question质疑；C. compare比较；D. track追踪。根据后文“how people respond to music”以及“Understanding the brain’s role”可知，要了解大脑的作用，就需要“追踪”人们对音乐的反应。故选D项。 12．考查动词词义辨析。句意：“理解大脑的作用可以解释为什么音乐能打动我们，”她说。A. explain解释；B. challenge挑战；C. imagine想象；D. change改变。根据前文“Understanding the brain’s role”以及后文“why music moves us”可知，了解大脑的作用是为了“解释”为什么音乐能打动我们。故选A项。 13．考查名词词义辨析。句意：这场竞赛不仅颁发了奖项，还证明了年轻创新者可以将爱好转化为造福社会的工具。A. program项目；B. experience经历；C. competition竞赛；D. system系统。根据前文“The 2023 Thermo Fisher JIC competition showcased this spirit.”可知，这里说的是2023年赛默飞世尔科技青少年创新者“竞赛”。故选C项。 14．考查名词词义辨析。句意：同上。A. skills技能；B. hobbies爱好；C. materials材料；D. data数据。根据前文“Amritha’s ___6___ came from her lifelong passion for music.”以及对Amritha的介绍可知，她出于对音乐的热爱开展项目，所以这里说的是年轻创新者可以将“爱好”转化为造福社会的工具。故选B项。 15．考查动词短语辨析。句意：正如Amritha的工作所展示的那样，科学好奇心与同理心相结合才能真正发挥作用。A. compared to与……相比；B. resulted in导致；C. paired with与……结合；D. absorbed in专注于。综合前文对Amritha项目的介绍，她出于对音乐的热爱开展项目，目的是改善人们的心理健康，这是科学好奇心与同理心的“结合”，且这种结合产生了积极影响。故选C项。 In many ways, Gitanjali Rao is an ordinary 11-year-old, lively and chatty.

So we played around with different ideas of how to 5 parents. We wanted to call and text parents using an Arduino and SIM card 6 . However, after lots of 7 , we felt there were too many chances to 8 the phone call, such as leaving your cell phone at home, or having 9 reception. We then took our ideas to the Arkansas Innovation Hub in Little Rock, where an engineer, Nick Jones, helped us further 10 our working prototype. We decided a pressure pad (垫) that connects the ground wire would start the Arduino. The future of this device has many different 11 . We would like a version that capitalizes on the 12 from a cigarette lighter to tell the Arduino that the car is 13 and it should now start checking for 14 changes.

The 2023 Thermo Fisher JIC competition showcased this spirit. Thirty finalists presented creative 1 to global issues, from environmental pollution to public health challenges. One standout participant was 14-year-old Amritha Praveen from Illinois. She built a system that uses people’s 2 to music to recommend songs that put them at ease. Her goal is to improve the 3 of music on mental health. Amritha’s system uses sensors to 4 someone’s heart rate while listening to music. Then, the system uses that information to recommend other music that is likely to help the person 5 . Amritha’s 6 came from her lifelong passion for music. She noticed how different music types caused 7 emotional reactions as a violin player. This 8 drove her to seek an objective method to measure the relaxation when listening to different types of music. Her research found two key factors leading to relaxation: musical key and timbre (音色) — the latter being a(n) 9 discovery. “Timbre’s role surprised me,” she admitted. “It refers to the tone color of sound.” Looking ahead, Amritha plans to 10 her project by studying how different types of instruments affect bodily responses and using brain waves to 11 how people respond to music. “Understanding the brain’s role could 12 why music moves us,” she said. The 13 not only awarded prizes but also proved that young innovators can turn   14 into tool for social good.

But her scientific 1 makes a huge difference. Last month, she won the top 2 at the Discovery Education 3M Young Scientist Challenge for her invention. What 3 Gitanjali’s work was that her city faced a water emergency with too much lead (铅) in its water. “The idea didn’t 4 to me until I saw my parents try to do water tests. The test strips may show inaccurate (不准确的) results, which weren’t very 5 ,” she recalls. She then searched for suitable materials with continued efforts and 6 found that carbon nanotube (纳米管) sensors could be used to sense chemicals. Gitanjali 7 to build a small blue housing using the 3D printer at her school with computer chips and a battery inside. A free app, which Gitanjali designed under the 8 from her computer science teacher, gives instant results and 9 the data to a linked phone through an attached device. The process of designing her project wasn’t always 10 , though. Kathleen Shafer, a scientist paired with Gitanjali as her teacher in summer, 11 along the way. In the award ceremony, Gitanjali also expressed her 12 to her parents for their constant support and 13 to try “crazy ideas”. Gitanjali received $25,000 to further develop her program along with the great 14 of winning the contest. According to Shafer, who 15 Gitanjali, “she shows a lot of motivation to solve practical issues through science.” 1．A．spirit B．training C．memory D．guide 2．A．support B．prize C．offer D．game 3．A．exposed B．improved C．inspired D．took 4．A．stick B．belong C．apply D．occur 5．A．reliable B．simple C．mild D．creative 6．A．immediately B．eventually C．sharply D．passively 7．A．promised B．managed C．pretended D．happened 8．A．observation B．command C．control D．instruction 9．A．sends B．owes C．explains D．attaches 10．A．optional B．complete C．smooth D．continuous 11．A．helped B．changed C．risked D．followed 12．A．thanks B．stresses C．opinions D．results 13．A．request B．encouragement C．struggle D．pressure 14．A．fortune B．intention C．impact D．honor 15．A．keeps with B．gets along with C．speaks highly of D．takes care of Instead of enjoying the summer vacation time like most junior middle school students, Feng Boyao and Meng Shuqi were busy 1 the Braille (布拉耶盲文) reading 2 they invented. Feng and Meng, students at No. 37 Middle School in Taiyuan, Shanxi Province, spent nearly a year developing a new kind of Braille reading device and won first prize at a recent provincial-level youth science and technology innovation 3 . The patented device was 4 for a national-level competition that 5 in Beijing. A large number of Braille 6 dots had been set up on the device. It could translate Braille content as a cursor (光标) moved across a computer screen via a computer application. They said the education for those people with visual 7 was mainly based on Braille books, but very few Braille books could be found in the marketplace, or they were 8 and couldn’t meet the needs of the blind. And only a small number of people had access to Braille reading devices, which are very 9 and might sell for as much as 10,000 yuan or more. “The 10 of our device is much lower, so it will be advantageous in terms of market 11 ,” they said. In addition, because of its magnetic structure, the content 12 on the device was said to be more 13 than others. “We hope our device can help reduce the proportion of blind people who become poor from 14 of education,” Meng said. “We also 15 to contribute our power to China’s poverty alleviation (扶贫) strategy.” 1．A．improving B．filling C．arming D．starting 2．A．book B．device C．engine D．form 3．A．examination B．meeting C．competition D．party 4．A．canceled B．hunted C．blamed D．entered 5．A．kicked off B．put off C．gave off D．took off 6．A．contact B．connect C．attach D．relate 7．A．barriers B．adaptation C．height D．disabilities 8．A．fashionable B．strict C．outdated D．tied 9．A．advanced B．popular C．expensive D．affordable 10．A．size B．cost C．distance D．rate 11．A．trust B．evidence C．flight D．promotion 12．A．reveal B．displayed C．admired D．fired 13．A．accurate B．lasting C．severe D．profound 14．A．use B．lack C．freedom D．delicacy 15．A．allow B．highlight C．wish D．permit Lost Wallet, Clever Code When one man found a wallet on a Saturday morning, he was 1 to return it — but 2 police stations were closed for the weekend, he had to get creative. Instead of 3 leaving the wallet in a drop box, where it wouldn’t be 4 until Monday, he decided to give the rightful 5 a chance to contact him directly — without 6 his own information to the public. Near the spot where he found the wallet, the man posted a flier (传单) with a(n) 7 trick. The note contained a simple but clever cryptographic (加密的) 8 : by entering his date of birth (which was on the ID in the wallet), the owner could 9 a set of numbers that revealed the man’s phone number. This 10 that only the real owner, who could confirm his ID, would be able to 11 him — preventing random strangers from falsely 12 the wallet. Later that day, the real owner called and was able to 13 his or her identity, reclaiming (取回) the lost belongings. He said he came up with the idea after watching a video on cryptography and hashing from a well-known online video platform. The platform is famous for its insightful (富有洞察力的) content on computer science, technology, and programming, making complex topics 14 to a broad audience.

At just 14 years old, Heman Bekele 1 as the victor of the 2023 3M Young Scientist Challenge, 2 among nine other finalists with his innovative 3 known as the Skin Cancer Treating Soap (SCTS). In 4 of his achievement, this ninth-grade boy is set to receive a substantial cash award of $25,00. In Bekele’s own words, “Curing cancer, one bar of 5 at a time.” His 6 for biology and technology was the driving force behind this clever creation, and the 3M Young Scientist Challenge 7 him with the perfect platform to showcase his 8 ideas. Reflecting on his inspiration, Bekele 9 that his childhood played a significant role in 10 his innovative thinking. Having 11 people work tirelessly under the sun, he couldn’t help but 12 how many were aware of the risks associated with prolonged sun exposure. “I wanted to make my idea not only scientifically exceptional but also accessible to a broad audience,” Bekele expressed during an interview. 13 , Bekele’s creation obtained the 14 of Food and Drug Administration. Over the coming five years, Bekele 15 to perfect his invention and establish a nonprofit organization dedicated to distributing his innovative creation to undersevisemen communities, offering hope and a practical solution in the fight against skin cancer. 1．A．led B．competed C．emerged D．acted 2．A．standing out B．pulling off C．getting through D．picking up 3．A．tool B．device C．idea D．creation 4．A．search B．recognition C．favour D．memory 5．A．iron B．soap C．chocolate D．cheese 6．A．passion B．respect C．taste D．desire 7．A．stuffed B．charged C．filled D．provided 8．A．new B．crazy C．original D．basic 9．A．shared B．proved C．denied D．hoped 10．A．breaking B．finding C．shaping D．changing 11．A．witnessed B．appreciated C．remembered D．helped 12．A．confirm B．wonder C．guess D．realize 13．A．Gradually B．Ultimately C．Directly D．Suddenly 14．A．qualification B．requirement C．procedure D．approval 15．A．affords B．agrees C．intends D．offers In 2023, a young boy in Arkansas died from being left in a hot car. The incident and the 1 were constantly on our local news, so this issue was fresh on our minds. We built our 2 in hopes that we could prevent this kind of 3 around the world. We began by building a basic prototype (原型) using Lego EV3. We were excited to see our 4 worked, but it didn’t actually connect to the car in any way. So we played around with different ideas of how to 5 parents. We wanted to call and text parents using an Arduino and SIM card 6 . However, after lots of 7 , we felt there were too many chances to 8 the phone call, such as leaving your cell phone at home, or having 9 reception. We then took our ideas to the Arkansas Innovation Hub in Little Rock, where an engineer, Nick Jones, helped us further 10 our working prototype. We decided a pressure pad (垫) that connects the ground wire would start the Arduino. The future of this device has many different 11 . We would like a version that capitalizes on the 12 from a cigarette lighter to tell the Arduino that the car is 13 and it should now start checking for 14 changes. It is important for us to continue to improve this tech, so we can give people some simple and 15 technology that can be used to help save the lives of children. 1．A．conflict B．sorrow C．assumption D．notice 2．A．room B．project C．factory D．office 3．A．death B．error C．injury D．barrier 4．A．talent B．knowledge C．concept D．discussion 5．A．engage B．persuade C．locate D．warn 6．A．politely B．intentionally C．initially D．accurately 7．A．debates B．conflicts C．preparations D．complaints 8．A．reject B．miss C．repeat D．forget 9．A．automatic B．unfamiliar C．temporary D．terrible 10．A．compare B．unfold C．check D．enhance 11．A．profits B．mysteries C．variations D．functions 12．A．signal B．loud C．smoke D．fire 13．A．switched on B．turned off C．pulled over D．put away 14．A．temperature B．weight C．movement D．capacity 15．A．advanced B．alternative C．affordable D．popular In Old Delhi, India, Yash Metha ran his fingers over the braille book in a school for the blind, his heart heavy. “Why don’t you use electronic braille readers?” he asked a student. “Too 1 ,” came the reply, a reply that stayed with him like a 2 . Back home in North Carolina, the 14-year-old 3 toy motors late at night, with the internal orange circuit (电路) boards exposed, shining like tiny lights. “What if vibrations (震动) could feel like braille dots?” he whispered to his confused cat. For weeks, 4 models filled his desk. “ 5 yet?” his sister joked when a motor produced small flashes of fire. Yash shook his head, remembering the Delhi students’ 6 eyes. He rebuilt the device using 3D printing, hands shaking as he conducted the final 7 and inspection. At the New Delhi Blind Relief Association, his shirt got wet from sweat. A girl named Priya tried the vibrating device. “ 8 !” she cried, reading most words 9 . Yash’s eyes watered — not because of 10 , but because of Priya’s bright smile. His 11 later won national awards, but Yash 12 noticed the victory. “Add text-scanning next,” he wrote in his notebook, dreaming of turning printed books into braille. When asked to give some advice to 13 lovers, Yash says, “Try to find something that you think could be done at your skill 14 . Even if you have to grow a little bit more in knowledge. Also, ask people in your community what problems they need to solve. I think that’s the most 15 part — getting first-hand feedback.” 1．A．diverse B．innovative C．flexible D．costly 2．A．trend B．concept C．shadow D．phenomenon 3．A．depended on B．took apart C．took advantage of D．kept up with 4．A．broken B．reliable C．adaptable D．abandoned 5．A．Quit B．Stand C．Support D．Explode 6．A．enhanced B．desired C．involved D．confirmed 7．A．figure B．strategy C．test D．advice 8．A．Terrifying B．Confusing C．Moving D．Amazing 9．A．specifically B．correctly C．seriously D．completely 10．A．expectation B．heart C．tiredness D．foundation 11．A．reward B．distribution C．representation D．invention 12．A．barely B．incredibly C．potentially D．apparently 13．A．commitment B．research C．study D．science 14．A．variety B．level C．choice D．category 15．A．grateful B．unique C．significant D．complex Katherine was born with cerebral palsy, and because of it, the now 19-year old has used a wheelchair her entire life. When her dad, Barry Dean, became concerned about the 1 of her tipping over in her wheelchair, he decided to do something about it. A little over two years ago, he began collaborating with his brother Jered who also happens to be a/an 2 . “We realized no one else was working on this problem in a 3 way so we set out to create a 4 for Katherine,” Barry said in a press release. “This started out as a hobby and we were hacking Katherine’s wheelchair to help her out, and the 5 was once we were done with this we would get her the real technology,” Jered says in a video. He 6 a functioning prototype(原型) that “wouldn’t let her run into things or 7 steps” and that would “let her go out in the backyard by herself and get her help when she needed it.” As it turned out, there wasn’t any existing technology out there. So the brothers decided to start a company to bring their 8 to the public. “What started as a labor of 9 among family members has ultimately 10 a safer, more stable way for people with disabilities to navigate their world and stay 11 to loved ones,” Barry said. The result was LUCI, a hardware and software platform that mounts onto a power 12 and “uses sensor-fusion technologies to allow it to ‘see’ its environment and avoid collisions(碰撞), 13 dangerous drop-offs, and provide 14 , security and cloud connectivity.” Best of all, it can be attached to a wheelchair so people don’t have to 15 a new one. 1．A．challenge B．risk C．opportunity D．necessity 2．A．reporter B．advertiser C．engineer D．lawyer 3．A．meaningful B．complex C．conventional D．flexible 4．A．directory B．job C．company D．solution 5．A．description B．fantasy C．assumption D．result 6．A．operated B．developed C．restored D．withdrew 7．A．drive off B．pay forward C．turn against D．carry through 8．A．expression B．discovery C．invention D．inference 9．A．fortune B．love C．anxiety D．comfort 10．A．evolved B．created C．changed D．reformed 11．A．cooperated B．reunited C．acknowledged D．connected 12．A．wheelchair B．seat C．mixer D．motorcycle 13．A．prevent B．preserve C．present D．perceive 14．A．elegance B．simplicity C．stability D．capacity 15．A．exchange B．substitute C．rent D．purchase 重难语篇提升练 Seven years ago, Naaz Ozair’s life took a heartbreaking turn when he lost his young nephew to cancer. The tragedy left him searching for answers, and he found a（n） 1 reality: Even small plastic particles could 2 severe health issues like cancer. 3 to turn his pain into action, Naaz made it his mission to 4 plastic use in our daily lives. As a teacher in Muzaffarpur, India at the time, he was good at solving complex problems. After many failed 5 to discover a practicable plastic alternative, Naaz 6 an unexpected solution: corn husk（玉米皮）。 What started as an experiment quickly 7 something much bigger. Naaz began making 8 products, including chocolate wrappers, cups, etc.—all from corn husk. His business now has over 10 different products, and he’s selling more than 1, 000 items daily. However, the path to 9 wasn’t easy. To make a real difference, Naaz left behind his stable teaching career, devoting his time and energy 10 to research and product development. Naaz’s products not only help reduce plastic waste but also 11 local farmers in his region, providing them with an additional 12 , where corn is grown three times a year. Today, Naaz’s work is 13 by the local government and he’s focused on expanding his business.
