(三月份期间，我们在全馆各展区致敬STEM领域的女性。)”和“This list of honorees is meant to spark conversation and also highlight the many accomplishments of women in STEM. (这份荣誉名单旨在引发讨论，同时突出女性在STEM领域取得的诸多成就。)”可知，三月展览活动的主要目的是表彰在STEM领域做出杰出贡献的女性。 22．细节理解题。根据Maryam Mirzakhani部分的“She created essential tools that mathematicians say will continue to shape the field for years to come. (她创造了重要的工具，数学家们说这些工具将在未来多年继续塑造这个领域。)”可知，Maryam Mirzakhani的研究工具将在未来很长时间内影响数学领域。 23．细节理解题。根据Kimberly Bryant部分的“Using experience gained through multiple leadership positions at major corporations, she founded Black Girls Code, a computer science and technology training course for girls from underrepresented communities that has grown into a global program. (凭借在多家大型企业担任多个领导职务所积累的经验，她创立了Black Girls Code，这是一项面向来自代表性不足群体的女孩的计算机科学与技术培训项目，现已发展为全球性项目。)”可知，Kimberly Bryant创办Black Girls Code是为了支持来自代表性不足群体的女孩。 （本题10分）After a terrible accident left college student Vhan McGuire paralyzed (瘫痪), a team of engineering students stepped in with an incredible solution — building a custom all-terrain (全地形) wheelchair that’s giving him the freedom to explore the outdoors again. McGuire, an architecture student, had always loved hiking, camping, and spending time in nature. But a motorcycle accident in October 2024 changed everything, limiting where he could go and what he could do. “A regular wheelchair struggles on any surface that isn’t hard or flat,” McGuire said. The limitation had long been a source of frustration in his daily life. Then, a chance introduction changed everything. A friend connected him with a group of engineering students at Tennessee Tech University who were searching for a meaningful, real-world challenge. That’s when Braden Hopper, John Avery, and Luke White decided to take on something special. Together, they built a custom all-terrain wheelchair they call “The Chariot”. The result is nothing short of incredible — a rugged, powerful chair designed to handle outdoor terrain and bring back the freedom McGuire thought he had lost. Now, instead of watching life from the sidelines, McGuire’s back outside doing what he loves. “Now, having a piece of equipment that can go anywhere — and that I feel comfortable with is a wonderful thing,” McGuire said. “This gets me back to what I loved doing and how I loved living before my accident.” Perhaps he summed it up best with just a few powerful words, “It gives me back my legs.” What began as a class project became a life-changing gift — proving that a little creativity and compassion (怜悯) can go a long way in helping someone regain their world. 24．(2.5分)What can we know about Vhan McGuire from paragraph 2? A．He was forced to go outdoors. B．He was a nature lover. C．He was an influential student. D．He was to blame for the accident. 25．(2.5分)What is the problem with regular wheelchairs? A．They can’t run on all terrains. B．Their usage time is limited. C．They often cause troubles. D．Their surface isn’t smooth. 26．(2.5分)What was the initial purpose of building “The Chariot”? A．To raise money for charity. B．To challenge regular wheelchairs. C．To win a competition. D．To complete a class project. 27．(2.5分)How did Vhan McGuire probably feel about the engineering students? A．Upset. B．Annoyed. C．Grateful. D．Concerned. 【答案】24．B 25．A 26．D 27．C 【导语】文章主要讲述了一群工程专业学生通过创新协作，为因车祸瘫痪的大学生 Vhan McGuire 设计并制作了一辆定制全地形轮椅，帮助他重新获得探索户外自由的故事。 【详解】24．细节理解题。根据第二段“McGuire, an architecture student, had always loved hiking, camping, and spending time in nature.(McGuire是一名建筑系学生，一直热爱徒步、露营以及在大自然中度过时光)”可知，Vhan McGuire是一位热爱大自然的人。 25．细节理解题。根据第三段““A regular wheelchair struggles on any surface that isn’t hard or flat,” McGuire said.(“普通轮椅在任何不坚硬或不平坦的表面上都难以行驶。”McGuire说)”可知，普通轮椅不适用全地形。 26．细节理解题。根据第四段“A friend connected him with a group of engineering students at Tennessee Tech University who were searching for a meaningful, real-world challenge.(一位朋友将他介绍给了田纳西理工大学的一群工程系学生，他们正在寻找一个有意义且具有现实意义的挑战)”及最后一段“What began as a class project became a life-changing gift — proving that a little creativity and compassion (怜悯) can go a long way in helping someone regain their world.(最初只是一个课程项目，却变成了一份改变人生的礼物——证明了些许创意与怜悯，足以帮助一个人重新找回属于自己的世界)”可知，这些工科专业的学生最初制作The Chariot的目的是完成一项课程项目。 27．推理判断题。根据倒数第二段““Now, having a piece of equipment that can go anywhere — and that I feel comfortable with is a wonderful thing,” McGuire said. “This gets me back to what I loved doing and how I loved living before my accident.”(“现在，拥有一台可以去往任何地方、而且让我感到安心的设备，是一件非常棒的事，”McGuire说，“这让我重新回到了我曾经热爱的事情，以及在事故发生前我所喜欢的生活方式。”)”可推断，Vhan McGuire很感激这些学生。 （本题10分）For decades, movie studios have relied on advance screenings to assess how audiences respond to in-development films, with viewer reactions informing edits, re-shoots and even changed endings. Studios typically collect qualitative feedback that always relies on memory after films end — if audiences in the busy streaming age even finish watching. But researchers at the University of Bristol in England now seek to modernize this method with a first-of-its-kind “smart” movie theater that measures viewers’ instantaneous physical reactions with high-tech equipment. Located on the institution’s new campus, the 35-seat Smart Cinema pairs the familiar high-resolution laser (激光) projector and Dolby surround-sound speakers with technologies foreign to most movie houses: heart rate monitors, EEG headsets and high-tech cameras. “With this smart cinema technology and with these methods, you don’t have to take the risk of releasing something and hoping it works. You can actually get real audience insight, moment by moment, into how they’re responding and then make changes before release,” says Iain Gilchrist, the co-author of a study that applied those methods. Researchers showed 40 people ten short TV clips of varying story types while collecting biometric (生物特征) data by monitoring viewers’ pulses (脉搏), brain waves, body heat, skin responses and eye movements. The research team found that viewers’ attention and personal involvement had connections with heart rate matching and consistent eye movement, yet their capacity to follow story plots showed no such link. A short science fiction drama called RENO became the Smart Cinema’s first tested film this week, playing to roughly 200 viewers. Fittingly, the film explores the relationship between humans and artificial intelligence(AI) and was produced on an experimental stage at the university that makes use of virtual reality technology. “As a director, having the opportunity to conduct an audience test of RENO in the Smart Cinema is truly invaluable,” says Rob Hifle, the film’s director. “It’s not just about refining the film; it’s also about connecting with viewers, understanding their reactions. This experience will undoubtedly shape the final cut in ways I can’t yet imagine.” 28．(2.5分)What is the weakness of traditional movie audience feedback methods? A．They depend on later comments. B．They lead to unfinished movies. C．They record film viewers’ habits. D．They update methods frequently. 29．(2.5分)What was one finding about audiences the researchers got? A．Their biometric data were the same. B．Their focus was affected by film types. C．Their emotions matched eye movement shifts. D．Their story understanding relied on heart beats. 30．(2.5分)Why does the author mention RENO? A．To make an advertisement. B．To introduce a practice. C．To present an argument. D．To analyze a phenomenon. 31．(2.5分)What is the best title for the text? A．The Change of Theaters B．Filmgoers’ Vital Roles C．A New Type of Cinema D．Features of Modern Films 【答案】28．A 29．C 30．B 31．C 【导语】本文主要讲述了英国布里斯托大学研发的智能影院，借助高科技设备采集观众的实时生物反应数据，以此获取观影反馈，助力影片修改完善。 【详解】28．细节理解题。根据第二段中的“Studios typically collect qualitative feedback that always relies on memory after films end—if audiences in the busy streaming age even finish watching.(制片厂通常会收集定性反馈，而这类反馈往往要等到影片结束后依靠观众回忆才能获得——尤其在流媒体盛行的当下，观众甚至未必能完整看完一部影片。)”可知，传统方式依靠观众观影结束之后凭借记忆给出的事后评价。 29．细节理解题。根据第四段中的“The research team found that viewers’ attention and personal involvement had connections with heart rate matching and consistent eye movement, yet their capacity to follow story plots showed no such link.(研究团队发现，观众的注意力与个人投入程度和心率同步性、眼球运动一致性存在关联，但观众理解故事情节的能力并未表现出此类联系。)”可知，观众的情绪投入和眼球运动变化相关。 30．细节理解题。根据第五段中的“A short science fiction drama called RENO became the Smart Cinema’s first tested film this week, playing to roughly 200 viewers.(一部名为《RENO》的短篇科幻短剧本周成为智能影院首部试映影片，约有 200 名观众观看。)”可知，作者列举RENO，是介绍智能影院投入实际测试的一项实践案例。 31．主旨大意题。文章第一段介绍传统影院点映收集观影反馈的行业背景，第二段引出本文的主旨句“But researchers at the University of Bristol in England now seek to modernize this method with a first‑of‑its‑kind “smart” movie theater that measures viewers’ instantaneous physical reactions with high‑tech equipment.(但英国布里斯托大学的研究人员如今试图革新这一方法，打造全球首个‘智能’影院，借助高科技设备实时测量观众的即时生理反应。)”，后文围绕这款新型智能影院的配套设备、相关研究发现、实际测试案例展开。C项表示“一种新型影院”，涵盖本文主旨，适合作本文标题。 （本题10分）In the US, almost 100 million people report being birdwatchers. In the UK, hundreds of thousands participate in the annual “Big Garden Birdwatch.” Beyond the obvious skills of identifying birds, is it possible that birdwatching is beneficially rewiring our brains? A just-published study in the Journal of Neuroscience provides some of the best evidence to date that this popular hobby can do just that. Scientists in Toronto were curious about brain differences between expert birdwatchers and beginners. To study them, they recruited 58 adults across a large age range, half expert bird identifiers, half less skillful. Using MRI, they studied brain structure and activation while participants identified birds. Compared with beginners, experts showed more compact brain structure in regions involved in attention and visual perception. The more compact the structure, the better the ability to identify birds. Interestingly, these same regions lit up on imaging when experts identified less familiar birds. While this was a small non-interventional study, it suggests that birdwatching to the point of expertise may rewire and restructure the brain. This builds on another study — “Creative experiences and brain clocks,” published in October 2025 in Nature Communications — which showed that people with more creative experience had more youthful-looking brains, directly related to their degree of expertise. More generally, participating in cognitively enriching activities may help delay dementia (痴呆症) onset; a Neurology study found that more engagement in such activities lowered Alzheimer’s risk by 38% and delayed diagnosis by 5 years on average for those eventually affected. Returning specifically to birdwatching, additional reasons support its brain benefits. Social connections top the list of brain-healthy factors, so joining a birdwatching group directly helps. The hobby promotes physical activity, an obvious brain benefit. Spending more time in nature, and stepping away from digital devices, also improves overall brain health. Finally, birdwatching may reduce stress — crucial because chronic stress impairs cognition and harms neural wiring. Much remains to learn about birdwatching’s potential for brain function and health. Yet while spending your day hunting a hummingbird or rare raptor does not replace a healthy diet, good sleep, and regular exercise, it may still be rewiring your brain for the better. 32．(2.5分)What brain differences did the study find between expert birdwatchers and beginners? A．Beginners had smaller visual brain areas. B．Beginners were better at identifying birds. C．Experts thought more thoroughly for unfamiliar birds. D．Experts had more tightly-organized attention brain areas. 33．(2.5分)Why does the author mention the study “Creative experiences and brain clocks”? A．To shift to a new subject. B．To support the above point. C．To offer background for the topic. D．To contrast with the previous study. 34．(2.5分)How does birdwatching benefit brains according to paragraph 4? A．It removes cognitive harm from stress. B．It helps people give up digital devices. C．Its social function best boosts brain health. D．Its physical benefits outweigh mental ones. 35．(2.5分)What can be a suitable title for the text? A．What Birdwatching Can Do for Your Brain? B．Why Expert Birders Have Better Attention Skills? C．Why Creative Experiences May Delay Dementia? D．How MRI Reveals the Secrets of Birdwatchers’ Brains? 【答案】32．D 33．B 34．C 35．A 【导语】主要介绍研究表明观鸟这项爱好能够重塑大脑结构，并从多方面阐述观鸟给大脑带来的各类益处。 【详解】32．细节理解题。根据第二段中的“Compared with beginners, experts showed more compact brain structure in regions involved in attention and visual perception. The more compact the structure, the better the ability to identify birds.(与新手相比，专家在负责注意力和视觉感知的脑区拥有更紧凑的大脑结构。结构越紧凑，识别鸟类的能力越强。)”可知，观鸟专家拥有组织更紧密的注意力相关脑区。 33．推理判断题。根据第三段中的“While this was a small non-interventional study, it suggests that birdwatching to the point of expertise may rewire and restructure the brain. This builds on another study — “Creative experiences and brain clocks,” published in October 2025 in Nature Communications — which showed that people with more creative experience had more youthful-looking brains, directly related to their degree of expertise. (尽管这是一项小型非干预性研究，但它表明，达到专业水准的观鸟活动可能会重塑并重构大脑。这是建立在另一项研究——2025年10月发表于《自然·通讯》的《创造性体验与大脑时钟》——的基础之上，该研究表明，拥有更多创造性体验的人，大脑看起来更年轻, 这与他们的专业水平直接相关。)”可知，作者引用这项研究是为佐证前文观鸟可重塑大脑的观点。 34．细节理解题。根据第四段中的“Social connections top the list of brain-healthy factors, so joining a birdwatching group directly helps. (社会交往位列有益于大脑健康因素的首位，因此加入观鸟团体能直接带来帮助。)”可知，观鸟的社交功能对促进大脑健康的作用最为突出。 35．主旨大意题。通读全文，尤其是第一段中的“Beyond the obvious skills of identifying birds, is it possible that birdwatching is beneficially rewiring our brains? A just-published study in the Journal of Neuroscience provides some of the best evidence to date that this popular hobby can do just that. (除了识别鸟类这项显而易见的技能之外，观鸟是否有可能正向重塑我们的大脑？《神经科学期刊》一项刚发表的研究，提供了迄今为止部分最有力的证据，证明这项流行的爱好确实可以做到这一点。)”可知，文章围绕观鸟这一爱好对大脑产生的各类积极影响展开，介绍相关科学研究以及多重益处，所以“What Birdwatching Can Do for Your Brain?(观鸟能为你的大脑带来什么？)”最能概括全文核心，适合作为最佳标题。 （本题12.5分）Nowadays, smart devices manage nearly every aspect of home life, from temperature regulation (调控) to security monitoring.

Nothing made me happier than seeing their eyes light up during these interactive and engaging activities. So I had never imagined that waste items would become our most valuable teaching resources, and that shortage would become the source of our greatest inspiration. Last year, our school was hit by severe budget cuts, which meant many resources for science activities were no longer available. As a teacher who had always relied on vivid experiments to make science fun, I felt extremely frustrated and discouraged. How could I keep my students interested and engaged without the well-equipped lab and expensive materials that had served us so well before? I was at a loss, worrying that my science classes would become boring and ineffective, and that my students would lose their passion for exploring the world through experiments. Just as I was struggling with this problem, my students surprised me in the most unexpected way. When we started our unit on simple machines, something amazing happened. Jamie, a ten-year-old boy full of curiosity, brought in some old bicycle parts from his garage. He said they could be used to make wheels and levers (控制杆). Following his example, Maya shared cardboard boxes that her family had kept for later use. One by one, other students also brought in recycled items: plastic bottles, string, used cans, and even small pieces of wood. By the end of the week, we had transformed the corner of our classroom into an entire “invention lab” using recycled materials and student contributions.

Groups gathered around desks piled high with plastic bottles, strings, cardboard boxes, and various waste items. Instead of following strict instructions from expensive commercial kits, they created, tested, and improved their own simple machines. Some used bicycle chains to build a pulley system, while others cut plastic bottles to create a water wheel. When their simple machine successfully lifted a small weight, cheers erupted. Through hands-on creation and repeated attempts, they developed a much deeper understanding of scientific principles. Their eyes shone with confidence and pride, which I had rarely seen before. By the end of the semester, we held a small exhibition for other classes. My students proudly showed off their creations, explaining how they used recycled materials to make something useful. It soon became a hit, inspiring many other classes to collect recycled materials for their own creative activities. The principal visited our classroom and was amazed by what we had accomplished. That day, I learned something no teacher training workshop had ever taught me: constraints don’t kill creativity — they set it free. When we involve students as partners in problem-solving, we tap into their creativity and resourcefulness while building genuine investment in their learning. 【导语】本文以人物为线索展开，讲述身为科学老师的作者向来依靠精密器材开展趣味实验。学校预算缩减后实验物资紧缺，作者倍感苦恼。不料学生们主动带来各类废旧物品，合力打造出简易创意实验室。这些废旧材料带来的学习效果，远超以往昂贵的专业实验器材。 【详解】1.段落续写： ①由第一段首句内容可以预测续写这段主要内容：学生们利用废旧物品自主制作简易机械，动手实践中深入领悟科学原理，满怀成就感。 ②由第二段首句内容可以预测续写这段主要内容：班级举办废品创意作品展广受好评，作者领悟到困境反而能激发学生的创造力。 2.续写线索：利用废旧物品创作——深入领悟科学原理——满怀成就感——创意作品展广受好评——作者满怀感悟 3.词汇激活 行为类 ①聚集：gather/assemble ②解释：explain/interpret ③鼓舞：inspire/motivate/encourage 情绪类 ①自豪地：proudly/with pride ②惊讶的：amazed/surprised/astonished 【点睛】[高分句型1] Their eyes shone with confidence and pride, which I had rarely seen before.（运用了which引导的非限制性定语从句） [高分句型2] The principal visited our classroom and was amazed by what we had accomplished.（运用了what引导的宾语从句） 2 / 2 2 / 2 学科网（北京）股份有限公司 $ 高中英语单元测试 —— Unit 1 Science and Scientists 学校:___________姓名：___________班级：___________考号：___________ 一、听力选择题 1．（本题1.5分）What does the man wish the robot could do?

Likewise, girls and women are faced with social and cultural barriers that can prevent them from studying STEM subjects in school or thriving in the workplace. We celebrate women in STEM fields throughout our exhibit floors during the month of March. We worked with teens in our Discovery Corps to identify women whose work is making a lasting impact. This list of honorees is meant to spark conversation and also highlight the many accomplishments of women in STEM. This is by no means a complete list. Tag us @PacSci on Facebook, Twitter, and/or Instagram to share the names of women scientists, innovators, and inventors in your life! Tu Youyou Inspired to pursue medicine after surviving tuberculosis as a teenager, Tu Youyou studied both modern and traditional practices, turning to ancient Chinese texts to find a cure for malaria. After learning that sweet wormwood was a traditional treatment for a common malaria symptom, Tu discovered a way to extract its active compound, artemisinin, saving millions of lives. In 2015, Tu became the first Chinese woman to win a Nobel Prize. Maryam Mirzakhani Maryam Mirzakhani was the first woman and first Iranian to win the Fields Medal (2014), the highest honor in mathematics. Mirzakhani solved complex, cross-disciplinary problems that had long puzzled mathematicians in fields such as dynamics, topology, and hyperbolic geometry. She created essential tools that mathematicians say will continue to shape the field for years to come. Kimberly Bryant As a black woman studying computer science and electrical engineering, Kimberly Bryant felt a sense of community was missing.

McGuire, an architecture student, had always loved hiking, camping, and spending time in nature. But a motorcycle accident in October 2024 changed everything, limiting where he could go and what he could do. “A regular wheelchair struggles on any surface that isn’t hard or flat,” McGuire said. The limitation had long been a source of frustration in his daily life. Then, a chance introduction changed everything. A friend connected him with a group of engineering students at Tennessee Tech University who were searching for a meaningful, real-world challenge. That’s when Braden Hopper, John Avery, and Luke White decided to take on something special. Together, they built a custom all-terrain wheelchair they call “The Chariot”. The result is nothing short of incredible — a rugged, powerful chair designed to handle outdoor terrain and bring back the freedom McGuire thought he had lost. Now, instead of watching life from the sidelines, McGuire’s back outside doing what he loves. “Now, having a piece of equipment that can go anywhere — and that I feel comfortable with is a wonderful thing,” McGuire said. “This gets me back to what I loved doing and how I loved living before my accident.” Perhaps he summed it up best with just a few powerful words, “It gives me back my legs.” What began as a class project became a life-changing gift — proving that a little creativity and compassion (怜悯) can go a long way in helping someone regain their world. 24．(2.5分)What can we know about Vhan McGuire from paragraph 2? A．He was forced to go outdoors. B．He was a nature lover. C．He was an influential student. D．He was to blame for the accident. 25．(2.5分)What is the problem with regular wheelchairs? A．They can’t run on all terrains. B．Their usage time is limited. C．They often cause troubles. D．Their surface isn’t smooth. 26．(2.5分)What was the initial purpose of building “The Chariot”? A．To raise money for charity. B．To challenge regular wheelchairs. C．To win a competition. D．To complete a class project. 27．(2.5分)How did Vhan McGuire probably feel about the engineering students? A．Upset. B．Annoyed. C．Grateful. D．Concerned. （本题10分）For decades, movie studios have relied on advance screenings to assess how audiences respond to in-development films, with viewer reactions informing edits, re-shoots and even changed endings. Studios typically collect qualitative feedback that always relies on memory after films end — if audiences in the busy streaming age even finish watching. But researchers at the University of Bristol in England now seek to modernize this method with a first-of-its-kind “smart” movie theater that measures viewers’ instantaneous physical reactions with high-tech equipment. Located on the institution’s new campus, the 35-seat Smart Cinema pairs the familiar high-resolution laser (激光) projector and Dolby surround-sound speakers with technologies foreign to most movie houses: heart rate monitors, EEG headsets and high-tech cameras. “With this smart cinema technology and with these methods, you don’t have to take the risk of releasing something and hoping it works. You can actually get real audience insight, moment by moment, into how they’re responding and then make changes before release,” says Iain Gilchrist, the co-author of a study that applied those methods. Researchers showed 40 people ten short TV clips of varying story types while collecting biometric (生物特征) data by monitoring viewers’ pulses (脉搏), brain waves, body heat, skin responses and eye movements. The research team found that viewers’ attention and personal involvement had connections with heart rate matching and consistent eye movement, yet their capacity to follow story plots showed no such link. A short science fiction drama called RENO became the Smart Cinema’s first tested film this week, playing to roughly 200 viewers. Fittingly, the film explores the relationship between humans and artificial intelligence(AI) and was produced on an experimental stage at the university that makes use of virtual reality technology. “As a director, having the opportunity to conduct an audience test of RENO in the Smart Cinema is truly invaluable,” says Rob Hifle, the film’s director. “It’s not just about refining the film; it’s also about connecting with viewers, understanding their reactions. This experience will undoubtedly shape the final cut in ways I can’t yet imagine.” 28．(2.5分)What is the weakness of traditional movie audience feedback methods? A．They depend on later comments. B．They lead to unfinished movies. C．They record film viewers’ habits. D．They update methods frequently. 29．(2.5分)What was one finding about audiences the researchers got? A．Their biometric data were the same. B．Their focus was affected by film types. C．Their emotions matched eye movement shifts. D．Their story understanding relied on heart beats. 30．(2.5分)Why does the author mention RENO? A．To make an advertisement. B．To introduce a practice. C．To present an argument. D．To analyze a phenomenon. 31．(2.5分)What is the best title for the text? A．The Change of Theaters B．Filmgoers’ Vital Roles C．A New Type of Cinema D．Features of Modern Films （本题10分）In the US, almost 100 million people report being birdwatchers. In the UK, hundreds of thousands participate in the annual “Big Garden Birdwatch.” Beyond the obvious skills of identifying birds, is it possible that birdwatching is beneficially rewiring our brains? A just-published study in the Journal of Neuroscience provides some of the best evidence to date that this popular hobby can do just that. Scientists in Toronto were curious about brain differences between expert birdwatchers and beginners. To study them, they recruited 58 adults across a large age range, half expert bird identifiers, half less skillful. Using MRI, they studied brain structure and activation while participants identified birds. Compared with beginners, experts showed more compact brain structure in regions involved in attention and visual perception. The more compact the structure, the better the ability to identify birds. Interestingly, these same regions lit up on imaging when experts identified less familiar birds. While this was a small non-interventional study, it suggests that birdwatching to the point of expertise may rewire and restructure the brain. This builds on another study — “Creative experiences and brain clocks,” published in October 2025 in Nature Communications — which showed that people with more creative experience had more youthful-looking brains, directly related to their degree of expertise. More generally, participating in cognitively enriching activities may help delay dementia (痴呆症) onset; a Neurology study found that more engagement in such activities lowered Alzheimer’s risk by 38% and delayed diagnosis by 5 years on average for those eventually affected. Returning specifically to birdwatching, additional reasons support its brain benefits. Social connections top the list of brain-healthy factors, so joining a birdwatching group directly helps. The hobby promotes physical activity, an obvious brain benefit. Spending more time in nature, and stepping away from digital devices, also improves overall brain health. Finally, birdwatching may reduce stress — crucial because chronic stress impairs cognition and harms neural wiring. Much remains to learn about birdwatching’s potential for brain function and health. Yet while spending your day hunting a hummingbird or rare raptor does not replace a healthy diet, good sleep, and regular exercise, it may still be rewiring your brain for the better. 32．(2.5分)What brain differences did the study find between expert birdwatchers and beginners? A．Beginners had smaller visual brain areas. B．Beginners were better at identifying birds. C．Experts thought more thoroughly for unfamiliar birds. D．Experts had more tightly-organized attention brain areas. 33．(2.5分)Why does the author mention the study “Creative experiences and brain clocks”? A．To shift to a new subject. B．To support the above point. C．To offer background for the topic. D．To contrast with the previous study. 34．(2.5分)How does birdwatching benefit brains according to paragraph 4? A．It removes cognitive harm from stress. B．It helps people give up digital devices. C．Its social function best boosts brain health. D．Its physical benefits outweigh mental ones. 35．(2.5分)What can be a suitable title for the text? A．What Birdwatching Can Do for Your Brain? B．Why Expert Birders Have Better Attention Skills? C．Why Creative Experiences May Delay Dementia? D．How MRI Reveals the Secrets of Birdwatchers’ Brains? （本题12.5分）Nowadays, smart devices manage nearly every aspect of home life, from temperature regulation (调控) to security monitoring. A sudden power failure is more than a simple inconvenience. It can shut down your heating, cut off your network, and even leave your security system blind all at once. 36(2.5分) One of the benefits of a portable power station is the comfort it brings when the power fails. Imagine a storm hits, and suddenly, your heater or air conditioning shuts off. With a power station, you can keep essential devices running. 37(2.5分) This makes it quieter, cleaner, easier to maintain, and more suitable for indoor use. Being able to control appliances via Wi-Fi is one of the hallmarks of modern smart homes. However, if the power goes down, you lose access to that connectivity. Even if the power comes back in a few minutes, some of your appliances may not work properly after a forced restart. 38(2.5分) That way, you won’t lose connectivity during a blackout (停电). If you’ve invested in solar panels or another renewable energy source, a portable power station can be an excellent way to store energy. When the sun is shining, any extra energy generated by your solar panels can be stored in the portable power station. 39(2.5分) 40(2.5分) An entire security system will become blind without stable power. So if you want to make sure your system is fully functional during a blackout, you’d better have a portable power station as backup power. A．Don’t count on backup batteries for security.

The Xue-shan-mu-chang 15-meter SubMillimeter Telescope (XSMT) will be located in the city of Delingha, Qinghai Province, at an altitude of 4,800 meters. The project is scheduled 58(1.5分) (complete) in 2027. Designed with a 15-meter aperture (孔径), the XSMT will support high-frequency submillimeter wave (亚毫米波) observations. While traditional optical telescopes cannot see through the dust of the universe, submillimeter wave facilities can not only reveal the laws of galaxy formation and evolution 59(1.5分) also trace the origins of life-related molecules, 60(1.5分) is a process that plays a crucial role in studying the formation of stars and planets. 61(1.5分) the atmospheric water vapor content above the site should remain low and stable is one of the strict requirements for site conditions in submillimeter wave observations. The site of the telescope is located in the heart of the Qinghai-Tibet Plateau, known as “the roof of the world”, featuring conditions such as high altitude, 62(1.5分) (minimum) human interference and extremely low water vapor, making it 63(1.5分) ideal location for observations. China lacks self-built and 64(1.5分) (regular) operational observation facilities in the field of submillimeter wave astronomy. Upon its 65(1.5分) (conclude) in 2027, the XSMT will fill this gap. 五、书信写作 66．（本题15分）假定你是李华，你的外籍同学Peter对中国杰出人物很感兴趣，请你给他写一封邮件，介绍一位你最敬佩的中国人物，内容包括： 1.人物基本信息； 2.主要事迹与贡献； 3.你敬佩他/她的原因。 注意：词数100左右。 Dear Peter, _______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Yours, Li Hua 六、书面表达 67．（本题25分）阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。 For years, I had been using delicate experimental tools and advanced lab materials to bring complex scientific concepts to life for my students. Nothing made me happier than seeing their eyes light up during these interactive and engaging activities. So I had never imagined that waste items would become our most valuable teaching resources, and that shortage would become the source of our greatest inspiration. Last year, our school was hit by severe budget cuts, which meant many resources for science activities were no longer available. As a teacher who had always relied on vivid experiments to make science fun, I felt extremely frustrated and discouraged. How could I keep my students interested and engaged without the well-equipped lab and expensive materials that had served us so well before? I was at a loss, worrying that my science classes would become boring and ineffective, and that my students would lose their passion for exploring the world through experiments. Just as I was struggling with this problem, my students surprised me in the most unexpected way. When we started our unit on simple machines, something amazing happened. Jamie, a ten-year-old boy full of curiosity, brought in some old bicycle parts from his garage. He said they could be used to make wheels and levers (控制杆). Following his example, Maya shared cardboard boxes that her family had kept for later use. One by one, other students also brought in recycled items: plastic bottles, string, used cans, and even small pieces of wood. By the end of the week, we had transformed the corner of our classroom into an entire “invention lab” using recycled materials and student contributions. At first, I doubted whether these simple, everyday objects could support meaningful learning. However, it turned out the learning that happened in that makeshift (临时的) lab exceeded anything we had accomplished with expensive commercial kits. 注意：1．续写词数应为150左右； 2．请按如下格式在答题卡的相应位置作答。 In this makeshift lab, students worked with amazing enthusiasm. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ By the end of the semester, we held a small exhibition for other classes. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 2 / 2 2 / 2 学科网（北京）股份有限公司 $
