Pixel Building Opened: 2010 Use: Offices Designer: Decibel Architecture Location: Melbourne, Australia The Pixel Building proudly holds the title of Australia’s first CO2-free office building, which integrates an efficient water treatment system to harvest rainwater for diverse essential uses. In addition, it is totally powered by solar and wind energy generated on site. One Angel Square Opened: 2013 Use: Offices Designer: 3DReid Location: Manchester, United Kingdom One Angel Square is designed with flexibility in mind: The building’s structure and systems allow newcomers to easily rearrange and reorganize space to fit their needs. It also has a double-skinned outside surface to help reduce heating and cooling costs, underground pipes that bring in cool air through a heat exchanger, and stylish furniture made from recycled materials. CopenHill Opened: 2017 Use: Power plant & sports facility Designer: Bjarke Ingels Group(BIG) Location: Copenhagen, Denmark CopenHill is both a power plant that burns waste to generate electricity, and a sports facility where you can take on one of the world’s tallest climbing towers. But its most impressive offering is an artificial ski and snowboard track on the roof to provide recreation for the urban residents. Fukuoka Prefectural International Hall Opened: 1995 Use: Mixed used, including a concert hall Designer: Emilio Ambasz and Associates(EAA) Location: Fukuoka, Japan The project was born of limited options and creativity. Fukuoka residents were unhappy about losing their last public green space in the center of town. So architect Emilio Ambasz tried to make it up by bringing the public green space upward. As a result, one side of the building looks like a regular commercial building, but the other side has a series of 15 gardens that reach up to about 197 feet. 21．Which of the following is a green office building in Australia? A．CopenHill. B．One Angel Square. C．Pixel Building. D．Fukuoka Prefectural International Hall. 22．What is the building in Manchester known for? A．Low rents. B．Flexibly designed space.

C．They provide various sports facilities. D．They are built outside the city center. B Nearly four decades ago, Liu Qingjie, a hobbyist invention lover from Shandong, started chasing a “flying dream” — designing a functional flying machine. His effort to build a plane was met with cold suspicion: he spent over 1.5 million yuan and 10 years on experiments, yet villagers dismissed him as a hopeless dreamer and his family pressured him to quit. Back then, Liu saw his dream as a lonely battle. But things shifted when a local village official offered a game-changing suggestion, “Why not repurpose the design into a pesticide-spraying (农药喷洒) flying umbrella to assist farmers?” The idea clicked: Liu shifted his focus, trading a personal dream for a practical goal. Liu dived into the new project. Lacking expertise, he studied online guides and tested gliders (滑翔机) and hot air balloons — all crashed. Yet he grew “resistant” to setbacks, driven by the thought of helping his neighbors while still achieving his flying dream. The pesticide aircraft required two key features: ultra-short takeoff (for small farm fields) and stable low-level flight. After months of adjustments, he built a flying umbrella that met both needs. His first test was make-or-break. The flying umbrella took off. It flew at an overly sharp angle, nearly tearing its ropes apart — luckily, he landed safely. Next, he succeeded in the low-level test, flying steadily 3 meters above a balloon, which he’d never managed before. After fixing minor imperfections, he took it to the fields just as pesticide season began. A villager challenged him to a “human vs. machine” spray contest. The villagers rushed to start, but once Liu’s flying umbrella took off, it sped across the fields in seconds. Soon, the tired villagers slowed down; Liu finished first. The once-doubtful crowd now cheered. Liu’s dream hadn’t disappeared — it had transformed: what started as a mere personal ambition became a tool that lightened his neighbors’ burdens. 24．Why did Liu’s family disapprove of him? A．His invention didn’t benefit villagers. B．The villagers held a doubtful attitude. C．He spent too much money and energy. D．The government objected to his vision. 25．What can we know about Liu’s pesticide-spraying flying umbrella? A．It enhanced flexibility at great heights. B．It could extend long-distance range. C．It was capable of taking off in limited spaces. D．It enlarged the capacity to store pesticides. 26．Why was a “human vs. machine” spray contest launched? A．To prove the effectiveness of the flying umbrella. B．To fix the imperfection of the flying umbrella. C．To persuade villagers to use the flying umbrella. D．To draw authority’s concern about flying umbrella. 27．What is the best title for the text? A．The Battle Between Human and Machine B．The Challenges of Building a Pesticide Aircraft C．A Village’s Battle Against Farm Work Tiredness D．A Dream Redefined: From Disapproval to Applause C It has long been assumed that identical twins, who share nearly 100% of their genetic code, would have almost identical levels of intelligence. However, a recent study challenges this assumption, revealing that even with the same genes, significant differences in IQ can exist. The research focused on a unique aspect of biology: epigenetics (表观遗传学). Epigenetics involves chemical markers that attach to DNA．These marks don’t change the DNA sequence (序列) itself, but they can turn genes “on” or “off,” influencing how they are expressed. Think of DNA as the hardware of a computer — the fixed instructions. Epigenetic marks are then like the software that decides which programs run and how they operate. Scientists studied pairs of identical twins and found that while their DNA sequences were the same, their epigenetic landscapes were not. These epigenetic differences accumulate over a person’s lifetime due to factors like unique life experiences, different diets, exposure to distinct environmental pollutants, or even varied social interactions. The study discovered a strong correlation between these different epigenetic patterns and measurable differences in the twins’ IQ scores. In some pairs, the IQ difference was as large as that typically seen between two unrelated individuals. This finding is significant because it moves the conversation beyond the classic “nature vs. nurture” debate. It suggests a more complex mechanism: genes set the potential, but life experiences write an epigenetic layer on top, which fine-tunes how that potential is realized. This understanding helps explain why one twin might develop a different cognitive ability or even more likely to develop certain mental health conditions than the other. The implications of this research extend far beyond twins. It provides a biological explanation for how our personal experiences and environment actively shape our brain’s function and cognitive abilities throughout our lives, offering a new framework for understanding human intelligence and individual differences. 28．According to the passage, what is the traditional assumption about identical twins’ IQs? A．Their IQs are shaped by their upbringing and environment. B．They often have significant differences in IQ due to different lives. C．Their intelligence levels are almost the same due to identical genes. D．Their IQ scores are not influenced by genetic factors. 29．What can be inferred from the study’s findings about intelligence? A．Genes are the only factor that determines a person’s IQ level. B．Life experiences may cause changes in a person’s DNA sequence. C．Gene expression is regulated by environmental factors. D．The cognitive differences between twins are smaller. 30．What is the author’s attitude toward the findings of this study? A．Doubtful. B．Supportive. C．Neutral. D．Disappointed. 31．Where is this passage most likely taken from? A．A personal diary. B．A non-fiction novel. C．A history textbook. D．A science news report. D During this year’s Spring Festival, Mount Taishan introduced wearable robotic exoskeletons (外骨骼) designed to assist hikers, making the demanding climbing more accessible especially for elderly and physically-challenged visitors. One 68-year-old tourist reported immediate relief from leg pain and a sensation of being assisted uphill, confirming the device’s practical effectiveness. The 1.8-kilogram exoskeleton, co-developed by the Taishan Cultural Tourism Group and Shenzhen-based Kenqing Technology, wraps around the waist and thighs (大腿). Powered by artificial intelligence, it senses the wearer’s pace and movement to provide real-time assistance, effectively reducing tiredness and joint pressure. Officials stated that the exoskeletons were introduced specifically to enable elderly visitors to experience the mountain’s natural beauty firsthand, as traditional cable cars often limit scenic immersion. This innovative application has generated broader discussions about the technology’s potential in addressing elderly care challenges within China’s rapidly aging society. The newest data reveals that by the end of 2024, China had 310 million citizens aged 60 or above, accounting for 22% of the total population. This proportion is projected to rise to 30% by 2035. Recognizing this vast market, Kenqing Technology has developed a dedicated lightweight exoskeleton system for elderly users, integrating advanced sensors and motion control to assist with walking, running, and climbing. The company plans to release an upgraded model this year, featuring lighter materials and more intelligent algorithms (算法) for better adaptability. Government policy actively encourages this sector’s development. National guidelines promote new models of intelligent health and elderly care, support the use of service robots, and foster the assistive recovery device industry. Industry experts and company executives agree that such policy support, combined with market forces, is essential to achieve large-scale adoption. They emphasize that widespread use will ultimately reduce production costs, making these assistive technologies more affordable for families across the country. 32．According to paragraph 1, what is one reported effect of using the exoskeleton? A．Complete relief from joint pain. B．Feeling of being supported upward. C．Immediate increase in hiking speed. D．Significant weight reduction for users. 33．The underlined word “immersion” in paragraph 2 refers to the experience of being ______. A．visually restricted B．financially supported C．physically surrounded D．technologically assisted 34．What is the primary reason for developing a new exoskeleton model this year? A．To better serve elderly users’ needs. B．To target younger hiking enthusiasts. C．To compete with cable car companies. D．To reduce government policy reliance. 35．What is the government’s attitude towards the future of robotic exoskeletons? A．Uncertain. B．Dismissive. C．Concerned. D．Supportive. 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Today, screens have become an inseparable part of human life. 36 While technology offers numerous benefits, excessive screen time can negatively impact their health. If you are parents, the following are a number of beneficial tips that can help keep your children active and healthy in the digital world. Setting very clear rules for screen time is the first step. Regardless of age, it is important for children to have consistent limits on it daily. Make sure to spell these limits out loud and clear for children, explaining to them why such limits have been set in place. 37 It is also very important to balance screen time with outdoor play and exercise. 38 As you know, interest is the best teacher. And regular exercise helps them develop the motor skills of the body, builds strength, and keeps them at a healthy weight. 39 For example, the interactive games get kids up and moving around through dancing or sports-type video games. Setting activity challenges is also helpful. During screen time, challenge your children by taking breaks and doing brief physical activities. Challenge them to ten jumping jacks, running on the spot, or stretching every 30 minutes. Many children tend to imitate(模仿)their parents’ behavior. Therefore, the first step toward developing good screen habits involves being a role model. 40 Besides, make it a point to discuss media use openly with your children to guide them effectively. A．Parents and children should establish a good relationship. B．If necessary, carry out this with the help of parental control tools. C．Separating study time from play time is the most suitable for them. D．Limit your own screen time and engage in the face-to-face interactions. E．Motivate your children to get involved in different sports that they enjoy. F．From study to play, children are increasingly exposed to electronic devices. G．Combining screen time with physical activities can help engage children more. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Lila had been silent for years. Born with hearing loss, the 16-year-old 41 to follow classroom discussions or chat with peers — her world was a quiet, lonely place where smiles often felt 42 . That changed when Lila tried on the Leion Hey2 AR glasses. As her teacher spoke, words appeared softly before her eyes, clear and in time with the voice. For the first time, she didn’t miss a joke shared by classmates or a key point in history class. When her best friend 43 closely, “You look happy today,” the glasses translated it 44 — and Lila replied aloud, drawing 45 cries from those around her. The team behind the glasses listened to Lila’s stories of loneliness, of missing out on laughter, and built the device for her. So this wasn’t just technology; it was a bridge built with 46 . The inventors of Leion Hey2 spent years listening to people like Lila, understanding that hearing loss isn’t just a physical barrier but an 47 one. They crafted the 49-gram glasses to be lightweight, so users could wear them all day, and 48 AI that captures even 49 voices in noisy rooms. Their goal wasn’t to create a fancy device, but to restore confidence and 50 — to let everyone feel seen and heard. Witnessing Lila’s 51 , I realized true goodness often hides in small, 52 acts. Innovation becomes beautiful not when it 53 advanced features, but when it bends to human needs. The Leion Hey2 glasses don’t just “see sound” — they bring kindness into daily life, proving that the most powerful technology is the one that lifts others up. In a world 54 progress, the best inventions and the best hearts, are those that choose to connect rather than 55 . 41．A．attempted B．pretended C．managed D．struggled 42．A．forced B．shared C．brightened D．softened 43．A．shouted B．mentioned C．whispered D．announced 44．A．instantly B．correctly C．slowly D．finally 45．A．sharp B．joyful C．loud D．painful 46．A．profit B．care C．speed D．curiosity 47．A．effective B．abstract C．emotional D．immediate 48．A．learned B．placed C．tied D．integrated 49．A．soft B．loud C．steady D．clear 50．A．friendship B．cooperation C．connection D．membership 51．A．situation B．action C．information D．transformation 52．A．awful B．clever C．thoughtful D．brave 53．A．adapts to B．shows off C．turns on D．takes up 54．A．blocking B．chasing C．making D．praising 55．A．divide B．escape C．limit D．control 第二节（共10小题：每小题1. 5分, 满分15分） 阅读下面短文, 在空白处填入1个适当的单词或括号内单词的正确形式。 Zhao Yang is a researcher at the Shapotou Desert Research Station, 56 is celebrated for creating the straw-checkerboard technique (草方格沙障技术) used over 60 years. His work aims to develop faster desert-control methods. Naturally, the formation of a sand-stabilizing crust (固沙结皮) requires about a decade. In contrast, combining lab-cultured cyanobacteria with a special bacterial strain 57 (extract) from local soil, Zhao’s team has 58 (dramatic) reduced this period to a single year, showcasing a significant technological leap. All this represents the latest chapter in China’s continuous fight 59 desertification. Decades ago, when China’s first desert railway opened in 1958, foreign experts once predicted its 60 (bury) by sand within 30 years—a prediction defeated by the simple yet highly effective straw-checkerboards, a technique pioneered in China. Building on this legacy, a new highway across the Tengger Desert is now expected 61 (complete) in the near future. In recent years, the national campaign 62 (strengthen) on a large scale, with millions of hectares treated annually. 63 (achieve) remarkable success domestically, China has also actively shared its practical expertise with other countries since 2005. For scientists like Zhao, the ultimate goal is not the elimination of deserts 64 the creation of a harmonious balance, recognizing them as 65 (value) parts of the Earth’s ecosystem. 第四部分 写作（共两节, 满分40分） 第一节（满分15分） 66．你校英文报正在举办题为“Science and Technology Change Life”的征文活动。请你写一 篇短文投稿，内容包括： (1)介绍一项科学技术； (2)说明其对你的影响。 注意： (1)写作词数应为80个左右； (2)请按如下格式在答题卡的相应位置作答。 Science and Technology Change Life ______________________________________________________________________________________________________________________________________________________________________________________ 第二节（满分25分） 67．阅读下面短文，根据其内容和所给段落的开头语续写一段，使之构成一篇完整的短文。 Harry was a 14-year-old boy. He was a quiet junior high school student. He was not an inventor, but he helped people change. He was the one who often cleaned out his family’s fridge. Every Sunday, he would find forgotten leftovers, wilted (枯萎的) vegetables, and expired yogurts that were not safe to eat. “We just bought this last week!” his mom would sigh, throwing a half-full box into the bin. The waste bothered Harry: It was like throwing money and food away straight into the trash. Then a simple idea came up to him. He began writing “EAT ME FIRST!” on sticky notes and putting them on the leftovers. It worked a little, but he still wanted a better system. For his school science project, Harry created “Keeper Tags.” They were simple, colorful magnetic tags with a dial (转盘) you could turn. Each tag had three colored parts: Green (Fresh!) , Yellow (Eat Soon!) , and Red (Last Call!) . When you put food in the fridge, you clipped a tag to it, turned the dial to green, and wrote the food’s name. After a few days, you turned the dial to yellow, then to red. Soon, the fridge door was full of bright colors that showed what to eat first. Harry tested the tags in his house for a month. Their food waste dropped by nearly70%. All his family loved the colourful reminder. It even became a game for his 5-year-old little sister to check the tags. Harry’s teacher encouraged him to share the idea online.

Pixel Building Opened: 2010 Use: Offices Designer: Decibel Architecture Location: Melbourne, Australia The Pixel Building proudly holds the title of Australia’s first CO2-free office building, which integrates an efficient water treatment system to harvest rainwater for diverse essential uses. In addition, it is totally powered by solar and wind energy generated on site. One Angel Square Opened: 2013 Use: Offices Designer: 3DReid Location: Manchester, United Kingdom One Angel Square is designed with flexibility in mind: The building’s structure and systems allow newcomers to easily rearrange and reorganize space to fit their needs. It also has a double-skinned outside surface to help reduce heating and cooling costs, underground pipes that bring in cool air through a heat exchanger, and stylish furniture made from recycled materials. CopenHill Opened: 2017 Use: Power plant & sports facility Designer: Bjarke Ingels Group(BIG) Location: Copenhagen, Denmark CopenHill is both a power plant that burns waste to generate electricity, and a sports facility where you can take on one of the world’s tallest climbing towers. But its most impressive offering is an artificial ski and snowboard track on the roof to provide recreation for the urban residents. Fukuoka Prefectural International Hall Opened: 1995 Use: Mixed used, including a concert hall Designer: Emilio Ambasz and Associates(EAA) Location: Fukuoka, Japan The project was born of limited options and creativity. Fukuoka residents were unhappy about losing their last public green space in the center of town. So architect Emilio Ambasz tried to make it up by bringing the public green space upward. As a result, one side of the building looks like a regular commercial building, but the other side has a series of 15 gardens that reach up to about 197 feet. 21．Which of the following is a green office building in Australia? A．CopenHill. B．One Angel Square. C．Pixel Building. D．Fukuoka Prefectural International Hall. 22．What is the building in Manchester known for? A．Low rents. B．Flexibly designed space. C．Luxury furniture. D．Advanced music instruments. 23．What do the last two buildings have in common? A．They are powered by solar energy. B．They bring the public space upward. C．They provide various sports facilities. D．They are built outside the city center. 【答案】21．C 22．B 23．B 【导语】本文是一篇应用文。文章主要介绍了世界各地的几座特色建筑。 21．细节理解题。根据Pixel Building部分“Location: Melbourne, Australia(地点：澳大利亚墨尔本)”可知，Pixel Building位于澳大利亚。故选C。 22．细节理解题。根据One Angel Square部分“One Angel Square is designed with flexibility in mind: The building’s structure and systems allow newcomers to easily rearrange and reorganize space to fit their needs.(“安吉尔广场”在设计时就充分考虑到了灵活性：该建筑的结构和系统使得新入住者能够轻松地重新布置和重组空间，以满足他们的需求)”可知，这座建筑的内部空间设计比较灵活、能随机调整。故选B。 23．细节理解题。根据CopenHill部分“But its most impressive offering is an artificial ski and snowboard track on the roof to provide recreation for the urban residents.(但其最令人赞叹的设施是在屋顶上设置的人造滑雪和单板滑雪道，为城市居民提供了休闲娱乐的场所)”及Fukuoka Prefectural International Hall部分“So architect Emilio Ambasz tried to make it up by bringing the public green space upward. As a result, one side of the building looks like a regular commercial building, but the other side has a series of 15 gardens that reach up to about 197 feet.(因此，建筑师埃米利奥·安巴兹试图通过将公共绿地向上延伸来弥补这一缺陷。结果，该建筑的一侧看起来像一座普通的商业大楼，而另一侧则有15个花园，高度可达约197英尺)”可知，这两座建筑都是向“上”要公共空间。故选B。 B Nearly four decades ago, Liu Qingjie, a hobbyist invention lover from Shandong, started chasing a “flying dream” — designing a functional flying machine. His effort to build a plane was met with cold suspicion: he spent over 1.5 million yuan and 10 years on experiments, yet villagers dismissed him as a hopeless dreamer and his family pressured him to quit. Back then, Liu saw his dream as a lonely battle. But things shifted when a local village official offered a game-changing suggestion, “Why not repurpose the design into a pesticide-spraying (农药喷洒) flying umbrella to assist farmers?” The idea clicked: Liu shifted his focus, trading a personal dream for a practical goal. Liu dived into the new project. Lacking expertise, he studied online guides and tested gliders (滑翔机) and hot air balloons — all crashed. Yet he grew “resistant” to setbacks, driven by the thought of helping his neighbors while still achieving his flying dream. The pesticide aircraft required two key features: ultra-short takeoff (for small farm fields) and stable low-level flight. After months of adjustments, he built a flying umbrella that met both needs. His first test was make-or-break. The flying umbrella took off. It flew at an overly sharp angle, nearly tearing its ropes apart — luckily, he landed safely. Next, he succeeded in the low-level test, flying steadily 3 meters above a balloon, which he’d never managed before. After fixing minor imperfections, he took it to the fields just as pesticide season began. A villager challenged him to a “human vs. machine” spray contest. The villagers rushed to start, but once Liu’s flying umbrella took off, it sped across the fields in seconds. Soon, the tired villagers slowed down; Liu finished first. The once-doubtful crowd now cheered. Liu’s dream hadn’t disappeared — it had transformed: what started as a mere personal ambition became a tool that lightened his neighbors’ burdens. 24．Why did Liu’s family disapprove of him? A．His invention didn’t benefit villagers. B．The villagers held a doubtful attitude. C．He spent too much money and energy. D．The government objected to his vision. 25．What can we know about Liu’s pesticide-spraying flying umbrella? A．It enhanced flexibility at great heights. B．It could extend long-distance range. C．It was capable of taking off in limited spaces. D．It enlarged the capacity to store pesticides. 26．Why was a “human vs. machine” spray contest launched? A．To prove the effectiveness of the flying umbrella. B．To fix the imperfection of the flying umbrella. C．To persuade villagers to use the flying umbrella. D．To draw authority’s concern about flying umbrella. 27．What is the best title for the text? A．The Battle Between Human and Machine B．The Challenges of Building a Pesticide Aircraft C．A Village’s Battle Against Farm Work Tiredness D．A Dream Redefined: From Disapproval to Applause 【答案】24．C 25．C 26．A 27．D 【导语】这是一篇记叙文。文章讲述了山东发明爱好者刘清杰坚持追逐飞行梦，虽遭村民质疑、家人反对，但在村干部建议下将个人梦想转为实用发明，成功研制出农药喷洒飞伞，帮助农民减轻劳作负担，最终从被质疑变为被称赞的故事。 24．细节理解题。根据第一段“he spent over 1.5 million yuan and 10 years on experiments, yet villagers dismissed him as a hopeless dreamer and his family pressured him to quit.(他花费了150多万元和10年时间做实验，然而村民们认为他是不切实际的梦想家，他的家人也施压让他放弃)”可知，刘清杰的家人反对他是因为他花费了太多金钱和精力。故选C。 25．细节理解题。根据第四段“The pesticide aircraft required two key features: ultra-short takeoff (for small farm fields) and stable low-level flight. After months of adjustments, he built a flying umbrella that met both needs.(这种农药飞行器需要两个关键特性：超短距起飞（适用于小块农田）和稳定的低空飞行。经过数月调整，他造出了满足这两项需求的飞伞)”可知，刘清杰的农药喷洒飞伞能够在有限空间内起飞。故选C。 26．推理判断题。根据第六段“A villager challenged him to a “human vs. machine” spray contest.(一位村民向他发起了一场‘人机对战’的喷洒比赛)”以及前文村民对他的发明持怀疑态度可推知，举办这场比赛是为了证明飞伞的实际效果。故选A。 27．主旨大意题。通读全文可知，文章围绕刘清杰的梦想展开，他最初的个人飞行梦不被认可，后来将梦想重新定义为服务农民的实用发明，最终收获了众人的掌声。由此可知，D选项“重新定义的梦想：从反对到喝彩”最能概括文章主旨，适合用作标题。故选D。 C It has long been assumed that identical twins, who share nearly 100% of their genetic code, would have almost identical levels of intelligence. However, a recent study challenges this assumption, revealing that even with the same genes, significant differences in IQ can exist. The research focused on a unique aspect of biology: epigenetics (表观遗传学). Epigenetics involves chemical markers that attach to DNA．These marks don’t change the DNA sequence (序列) itself, but they can turn genes “on” or “off,” influencing how they are expressed. Think of DNA as the hardware of a computer — the fixed instructions. Epigenetic marks are then like the software that decides which programs run and how they operate. Scientists studied pairs of identical twins and found that while their DNA sequences were the same, their epigenetic landscapes were not. These epigenetic differences accumulate over a person’s lifetime due to factors like unique life experiences, different diets, exposure to distinct environmental pollutants, or even varied social interactions. The study discovered a strong correlation between these different epigenetic patterns and measurable differences in the twins’ IQ scores. In some pairs, the IQ difference was as large as that typically seen between two unrelated individuals. This finding is significant because it moves the conversation beyond the classic “nature vs. nurture” debate. It suggests a more complex mechanism: genes set the potential, but life experiences write an epigenetic layer on top, which fine-tunes how that potential is realized. This understanding helps explain why one twin might develop a different cognitive ability or even more likely to develop certain mental health conditions than the other. The implications of this research extend far beyond twins. It provides a biological explanation for how our personal experiences and environment actively shape our brain’s function and cognitive abilities throughout our lives, offering a new framework for understanding human intelligence and individual differences. 28．According to the passage, what is the traditional assumption about identical twins’ IQs? A．Their IQs are shaped by their upbringing and environment. B．They often have significant differences in IQ due to different lives. C．Their intelligence levels are almost the same due to identical genes. D．Their IQ scores are not influenced by genetic factors. 29．What can be inferred from the study’s findings about intelligence? A．Genes are the only factor that determines a person’s IQ level. B．Life experiences may cause changes in a person’s DNA sequence. C．Gene expression is regulated by environmental factors. D．The cognitive differences between twins are smaller. 30．What is the author’s attitude toward the findings of this study? A．Doubtful. B．Supportive. C．Neutral. D．Disappointed. 31．Where is this passage most likely taken from? A．A personal diary. B．A non-fiction novel. C．A history textbook. D．A science news report. 【答案】28．C 29．C 30．B 31．D 【导语】本文是一篇说明文。文章主要介绍了一项新的研究发现，即同卵双胞胎的智商可能存在显著差异，这一发现挑战了传统观念，并揭示了表观遗传学在智力发展中的作用。 28．细节理解题。根据第一段中“It has long been assumed that identical twins, who share nearly 100% of their genetic code, would have almost identical levels of intelligence. (长期以来，人们一直认为同卵双胞胎的基因几乎完全相同，因此他们的智力水平也几乎相同。)”可知，传统观念认为同卵双胞胎由于基因相同，智力水平也几乎相同。故选C项。 29．推理判断题。根据第二段中“Epigenetics involves chemical markers that attach to DNA. These marks don’t change the DNA sequence (序列) itself, but they can turn genes “on” or “off,” influencing how they are expressed. Think of DNA as the hardware of a computer — the fixed instructions. Epigenetic marks are then like the software that decides which programs run and how they operate. (表观遗传学涉及附着于DNA上的化学标记。这些标记本身不会改变DNA序列，却能像开关一样调控基因的“开启”或“关闭”，从而影响基因的表达方式。我们可以将DNA比作计算机的硬件——即固定的底层指令。而表观遗传标记则如同软件系统，决定着哪些程序被激活以及它们如何运行。)”以及第三段中“These epigenetic differences accumulate over a person’s lifetime due to factors like unique life experiences, different diets, exposure to distinct environmental pollutants, or even varied social interactions. (这些表观遗传差异会因个人独特的生活经历、不同的饮食、接触不同的环境污染物、甚至不同的社交互动等因素，而在人的一生中不断积累。)”可推知，环境因素(生活经历)会影响表观遗传，而表观遗传影响基因表达，这说明基因的表达受到环境因素的调控。由此推知，环境因素可以调节基因表达。故选C项。 30．推理判断题。根据最后一段“The implications of this research extend far beyond twins. It provides a biological explanation for how our personal experiences and environment actively shape our brain’s function and cognitive abilities throughout our lives, offering a new framework for understanding human intelligence and individual differences. (这项研究的影响远远超出了双胞胎的范围。它为我们的个人经历和环境如何在一生中积极塑造我们的大脑功能和认知能力提供了生物学解释，为理解人类智力和个体差异提供了一个新的框架。)”可知，作者认为这项研究的意义深远，为理解人类智力和个体差异提供了新的视角，由此可推知，作者对这项研究的态度是支持的。故选B项。 31．推理判断题。通读全文，尤其是第一段中“However, a recent study challenges this assumption, revealing that even with the same genes, significant differences in IQ can exist. (然而，最近的一项研究挑战了这一假设，揭示了即使基因相同，智商也可能存在显著差异。)”可知，章介绍了一项关于同卵双胞胎智力差异的最新科学研究，解释了其背后的表观遗传学机制，并探讨了研究的意义。这种客观报道最新科学发现的内容最有可能出现在科学新闻报道中。故选D项。 D During this year’s Spring Festival, Mount Taishan introduced wearable robotic exoskeletons (外骨骼) designed to assist hikers, making the demanding climbing more accessible especially for elderly and physically-challenged visitors. One 68-year-old tourist reported immediate relief from leg pain and a sensation of being assisted uphill, confirming the device’s practical effectiveness. The 1.8-kilogram exoskeleton, co-developed by the Taishan Cultural Tourism Group and Shenzhen-based Kenqing Technology, wraps around the waist and thighs (大腿). Powered by artificial intelligence, it senses the wearer’s pace and movement to provide real-time assistance, effectively reducing tiredness and joint pressure. Officials stated that the exoskeletons were introduced specifically to enable elderly visitors to experience the mountain’s natural beauty firsthand, as traditional cable cars often limit scenic immersion. This innovative application has generated broader discussions about the technology’s potential in addressing elderly care challenges within China’s rapidly aging society. The newest data reveals that by the end of 2024, China had 310 million citizens aged 60 or above, accounting for 22% of the total population. This proportion is projected to rise to 30% by 2035. Recognizing this vast market, Kenqing Technology has developed a dedicated lightweight exoskeleton system for elderly users, integrating advanced sensors and motion control to assist with walking, running, and climbing. The company plans to release an upgraded model this year, featuring lighter materials and more intelligent algorithms (算法) for better adaptability. Government policy actively encourages this sector’s development. National guidelines promote new models of intelligent health and elderly care, support the use of service robots, and foster the assistive recovery device industry. Industry experts and company executives agree that such policy support, combined with market forces, is essential to achieve large-scale adoption. They emphasize that widespread use will ultimately reduce production costs, making these assistive technologies more affordable for families across the country. 32．According to paragraph 1, what is one reported effect of using the exoskeleton? A．Complete relief from joint pain. B．Feeling of being supported upward. C．Immediate increase in hiking speed. D．Significant weight reduction for users. 33．The underlined word “immersion” in paragraph 2 refers to the experience of being ______. A．visually restricted B．financially supported C．physically surrounded D．technologically assisted 34．What is the primary reason for developing a new exoskeleton model this year? A．To better serve elderly users’ needs. B．To target younger hiking enthusiasts. C．To compete with cable car companies. D．To reduce government policy reliance. 35．What is the government’s attitude towards the future of robotic exoskeletons? A．Uncertain. B．Dismissive. C．Concerned. D．Supportive. 【答案】32．B 33．C 34．A 35．D 【导语】本文是一篇新闻报道。主要介绍今年春节泰山引入可穿戴机器人外骨骼帮助徒步登山者，尤其是老年人和身体不便者，还阐述了其研发、市场潜力及政府对此的支持态度。 32．细节理解题。根据第一段中的“One 68-year-old tourist reported immediate relief from leg pain and a sensation of being assisted uphill, confirming the device’s practical effectiveness.(一位68岁的游客称腿部疼痛立即得到缓解，并有向上被助力的感觉，证实了该设备的实际效果)”可知，使用外骨骼的一个报告效果是有向上被支持的感觉。故选B项。 33．词义猜测题。根据第二段中的“Officials stated that the exoskeletons were introduced specifically to enable elderly visitors to experience the mountain’s natural beauty firsthand, as traditional cable cars often limit scenic immersion.(官员们表示，引入外骨骼是专门为了让老年游客能够亲身体验泰山的自然美景，因为传统缆车常常限制了对风景的immersion)”可知，坐缆车不能很好地让游客置身于风景之中，“immersion”指的是被景色环绕、身临其境的体验，即physically surrounded。故选C项。 34．推理判断题。根据第三段中的“Recognizing this vast market, Kenqing Technology has developed a dedicated lightweight exoskeleton system for elderly users, integrating advanced sensors and motion control to assist with walking, running, and climbing. The company plans to release an upgraded model this year, featuring lighter materials and more intelligent algorithms (算法) for better adaptability.(认识到这个巨大的市场，肯庆科技为老年用户开发了一款专用的轻型外骨骼系统，集成了先进的传感器和运动控制，以辅助行走、跑步和攀爬。该公司计划今年发布一款升级版，采用更轻的材料和更智能的算法，以提高适应性)”可知，今年开发新外骨骼模型的主要原因是为了更好地满足老年用户的需求。故选A项。 35．推理判断题。根据最后一段中的“Government policy actively encourages this sector’s development. National guidelines promote new models of intelligent health and elderly care, support the use of service robots, and foster the assistive recovery device industry.(政府政策积极鼓励这一领域的发展。国家指导方针推广智能健康和养老新模式，支持服务机器人的使用，并促进辅助康复设备产业的发展)”可知，政府对机器人外骨骼的未来持支持态度。故选D项。 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Today, screens have become an inseparable part of human life. 36 While technology offers numerous benefits, excessive screen time can negatively impact their health. If you are parents, the following are a number of beneficial tips that can help keep your children active and healthy in the digital world. Setting very clear rules for screen time is the first step. Regardless of age, it is important for children to have consistent limits on it daily. Make sure to spell these limits out loud and clear for children, explaining to them why such limits have been set in place. 37 It is also very important to balance screen time with outdoor play and exercise. 38 As you know, interest is the best teacher. And regular exercise helps them develop the motor skills of the body, builds strength, and keeps them at a healthy weight. 39 For example, the interactive games get kids up and moving around through dancing or sports-type video games. Setting activity challenges is also helpful. During screen time, challenge your children by taking breaks and doing brief physical activities. Challenge them to ten jumping jacks, running on the spot, or stretching every 30 minutes. Many children tend to imitate(模仿)their parents’ behavior. Therefore, the first step toward developing good screen habits involves being a role model. 40 Besides, make it a point to discuss media use openly with your children to guide them effectively. A．Parents and children should establish a good relationship. B．If necessary, carry out this with the help of parental control tools.

G．Combining screen time with physical activities can help engage children more. 【答案】36．F 37．B 38．E 39．G 40．D 【导语】本文是一篇说明文，短文聚焦数字时代孩子屏幕使用过多的问题，针对家长给出了一系列实用建议。 36．根据上文“Today, screens have become an inseparable part of human life.(如今，屏幕已成为人类生活中不可分割的一部分)”以及下文“While technology offers numerous benefits, excessive screen time can negatively impact their health.(尽管科技带来诸多益处，但过长的屏幕时间会对孩子的健康产生负面影响)”可知，空格处需衔接前文的“屏幕融入生活”，具体落脚到孩子身上，说明孩子在学习和玩耍中都频繁接触电子设备，从而自然引出后文“屏幕时间过长危害孩子健康”的问题。F选项“From study to play, children are increasingly exposed to electronic devices.(从学习到玩耍，孩子们接触电子设备的机会越来越多)”精准承接前文，将屏幕的影响聚焦到孩子群体，“from study to play”贴合孩子的日常场景，“increasingly exposed to”为后文“excessive screen time”做铺垫，符合语境。故选F项。 37．根据本段小标题“Setting very clear rules for screen time is the first step.(为屏幕时间设定明确的规则是第一步)”以及上文“Make sure to spell these limits out loud and clear for children, explaining to them why such limits have been set in place.(一定要向孩子清晰明确地说明这些限制，并向他们解释制定这些限制的原因)”可知，空格处需补充设定屏幕使用规则的辅助方式，进一步完善“设定规则”的具体做法。B选项“If necessary, carry out this with the help of parental control tools.(如有必要，可借助家长控制工具来执行这项规定)”中的“this”指代前文为孩子设定的屏幕时间限制，“parental control tools”是设定并执行规则的实用辅助手段，贴合家长的实际操作需求，是对前文内容的合理延伸，符合语境。故选B项。 38．根据本段小标题“It is also very important to balance screen time with outdoor play and exercise.(平衡屏幕时间与户外玩耍和锻炼也非常重要)”以及下文“As you know, interest is the best teacher. And regular exercise helps them develop the motor skills of the body, builds strength, and keeps them at a healthy weight.(众所周知，兴趣是最好的老师。规律的锻炼有助于孩子发展身体运动技能、增强体质并维持健康体重)”可知，空格处需贴合“平衡屏幕时间与锻炼”的核心，给出具体做法——激发孩子参与喜欢的运动，同时呼应后文的“兴趣”这一关键词。E选项“Motivate your children to get involved in different sports that they enjoy.(鼓励孩子参与他们喜欢的各类运动)”紧扣本段主题，“that they enjoy”与后文的“interest”形成直接呼应，点明通过培养运动兴趣来引导孩子进行户外锻炼，从而平衡屏幕时间，符合语境。故选E项。 39．此处为段落小标题，需精准概括本段核心内容。根据下文“For example, the interactive games get kids up and moving around through dancing or sports-type video games. Setting activity challenges is also helpful. During screen time, challenge your children by taking breaks and doing brief physical activities.(例如，互动游戏能让孩子起身活动，比如舞蹈类或运动类电子游戏。设定活动挑战也很有帮助，在孩子使用屏幕的过程中，让他们暂停下来做一些简单的身体活动)”可知，本段核心是建议将孩子的屏幕时间与身体活动结合起来，让孩子在使用屏幕的同时也能进行运动。G选项“Combining screen time with physical activities can help engage children more.(将屏幕时间与身体活动结合，能让孩子更积极地参与其中)”精准概括本段主旨，“Combining screen time with physical activities”是对后文所有具体做法的高度总结，统领全段内容，符合小标题要求。故选G项。 40．根据本段小标题“Many children tend to imitate their parents’ behavior. Therefore, the first step toward developing good screen habits involves being a role model.(很多孩子会模仿父母的行为，因此，培养孩子良好的屏幕使用习惯，首先要从家长做好榜样开始)”以及下文“Besides, make it a point to discuss media use openly with your children to guide them effectively.(此外，要注重与孩子坦诚交流媒体使用问题，以便有效引导他们)”可知，空格处需具体说明家长如何做好榜样，核心是家长自身要减少屏幕时间，做出正面示范。D选项“Limit your own screen time and engage in the face-to-face interactions.(减少你自己的屏幕时间，多进行面对面的交流)”紧扣“家长做好榜样”的核心，“Limit your own screen time”是家长为孩子树立良好屏幕使用习惯的关键做法，同时为后文的“与孩子交流”做铺垫，符合语境。故选D项。 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Lila had been silent for years.

He was a quiet junior high school student. He was not an inventor, but he helped people change. He was the one who often cleaned out his family’s fridge. Every Sunday, he would find forgotten leftovers, wilted (枯萎的) vegetables, and expired yogurts that were not safe to eat. “We just bought this last week!” his mom would sigh, throwing a half-full box into the bin. The waste bothered Harry: It was like throwing money and food away straight into the trash. Then a simple idea came up to him. He began writing “EAT ME FIRST!” on sticky notes and putting them on the leftovers. It worked a little, but he still wanted a better system. For his school science project, Harry created “Keeper Tags.” They were simple, colorful magnetic tags with a dial (转盘) you could turn. Each tag had three colored parts: Green (Fresh!) , Yellow (Eat Soon!) , and Red (Last Call!) . When you put food in the fridge, you clipped a tag to it, turned the dial to green, and wrote the food’s name. After a few days, you turned the dial to yellow, then to red. Soon, the fridge door was full of bright colors that showed what to eat first. Harry tested the tags in his house for a month. Their food waste dropped by nearly70%. All his family loved the colourful reminder. It even became a game for his 5-year-old little sister to check the tags. Harry’s teacher encouraged him to share the idea online. He posted a short video explaining the problem and his simple solution. 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。 The response was unexpected. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Before long, many families began using their own Keeper Tags. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】 The response was unexpected. The video quickly went viral, attracting attention from all corners. People were impressed by Harry’s simple yet effective solution to the common problem of food waste. Messages of praise and support flooded in, with many expressing their eagerness to try out the Keeper Tags in their own homes. Some even suggested improvements or offered to help spread the idea further. Harry was overwhelmed by the positive feedback, feeling a sense of accomplishment he had never experienced before.   Before long, many families began using their own Keeper Tags. The colorful magnetic tags became a popular sight in fridges across the neighborhood and even beyond. Stores started selling similar products inspired by Harry’s invention, and he was invited to share his story on local TV shows and in newspapers. More importantly, the amount of food waste in these families significantly decreased, just like in Harry's home. Harry’s simple idea had sparked a movement, proving that even a small change could make a big difference in the world. 【导语】本文以人物为线索展开，主要讲述了14岁的Harry为了解决家庭食物浪费问题，发明了“Keeper Tags”并分享到网络，引发了广泛关注的故事。 【详解】1.段落续写： ①由第一段首句内容“反应出乎意料。”可知，第一段可描写Harry的视频在网络上迅速传播，引发了大量关注和积极反馈，人们纷纷表示支持并想要尝试使用“Keeper Tags”。 ②由第二段首句内容“不久，许多家庭开始使用他们自己的“Keeper Tags””可知，第二段可描写“Keeper Tags”在更多家庭中得到应用，甚至被商店销售，Harry也因此受到邀请分享他的故事，更重要的是，食物浪费现象在这些家庭中显著减少。 2.续写线索：视频走红——获得关注与支持——更多家庭使用“Keeper Tags”——商店销售类似产品——Harry受邀分享故事——食物浪费减少——证明小改变也能带来大影响 3.词汇激活 行为类 ①吸引注意力：attract attention/draw attention ②尝试使用：try out/give it a try/have a go at ③建议改进：suggest improvements/put forward suggestions for improvement 情绪类 ①渴望：eagerness/keenness/desire ②成就感：a sense of accomplishment/a feeling of achievement/a sense of pride 【点睛】【高分句型1】Harry was overwhelmed by the positive feedback, feeling a sense of accomplishment he had never experienced before.（运用了that或which引导的限制性定语从句，that或which被省略） 【高分句型2】Harry’s simple idea had sparked a movement, proving that even a small change could make a big difference in the world.（运用了that引导的宾语从句） 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司22 / 23 学科网（北京）股份有限公司 $ 2025-2026学年高二英语选择性必修第三册单元自测（四川专用） Unit 5·培优卷 学校:___________班级：___________姓名：___________分数：___________ （时间：120分钟，满分：150分） 注意事项： 1. 答卷前，考生务必将自己的姓名、准考证号填写在答题卡上。 2. 回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上，写在本试卷上无效。 3. 考试结束后，将本试卷和答题卡一并交回。 第一部分 听力（共两节，满分 30 分） 做题时，请先将答案标在试卷上。录音内容结束后，你将有两分钟的时间将试卷上的答案转涂到答题卡上。 第一节（共5小题；每小题1.5分，满分7.5分） 听下面5段对话。每段对话后有一个小题，从题中所给的A、B、C三个选项中选出最佳选项。听完每段对话后，你都有10秒钟的时间来回答有关小题和阅读下一小题。每段对话读两遍。 1．Where does the conversation probably take place?

CopenHill Opened: 2017 Use: Power plant & sports facility Designer: Bjarke Ingels Group(BIG) Location: Copenhagen, Denmark CopenHill is both a power plant that burns waste to generate electricity, and a sports facility where you can take on one of the world’s tallest climbing towers. But its most impressive offering is an artificial ski and snowboard track on the roof to provide recreation for the urban residents. Fukuoka Prefectural International Hall Opened: 1995 Use: Mixed used, including a concert hall Designer: Emilio Ambasz and Associates(EAA) Location: Fukuoka, Japan The project was born of limited options and creativity. Fukuoka residents were unhappy about losing their last public green space in the center of town. So architect Emilio Ambasz tried to make it up by bringing the public green space upward. As a result, one side of the building looks like a regular commercial building, but the other side has a series of 15 gardens that reach up to about 197 feet. 21．Which of the following is a green office building in Australia? A．CopenHill. B．One Angel Square. C．Pixel Building. D．Fukuoka Prefectural International Hall. 22．What is the building in Manchester known for? A．Low rents. B．Flexibly designed space. C．Luxury furniture. D．Advanced music instruments. 23．What do the last two buildings have in common? A．They are powered by solar energy. B．They bring the public space upward. C．They provide various sports facilities. D．They are built outside the city center. B Nearly four decades ago, Liu Qingjie, a hobbyist invention lover from Shandong, started chasing a “flying dream” — designing a functional flying machine. His effort to build a plane was met with cold suspicion: he spent over 1.5 million yuan and 10 years on experiments, yet villagers dismissed him as a hopeless dreamer and his family pressured him to quit. Back then, Liu saw his dream as a lonely battle. But things shifted when a local village official offered a game-changing suggestion, “Why not repurpose the design into a pesticide-spraying (农药喷洒) flying umbrella to assist farmers?” The idea clicked: Liu shifted his focus, trading a personal dream for a practical goal. Liu dived into the new project. Lacking expertise, he studied online guides and tested gliders (滑翔机) and hot air balloons — all crashed. Yet he grew “resistant” to setbacks, driven by the thought of helping his neighbors while still achieving his flying dream. The pesticide aircraft required two key features: ultra-short takeoff (for small farm fields) and stable low-level flight. After months of adjustments, he built a flying umbrella that met both needs. His first test was make-or-break. The flying umbrella took off. It flew at an overly sharp angle, nearly tearing its ropes apart — luckily, he landed safely. Next, he succeeded in the low-level test, flying steadily 3 meters above a balloon, which he’d never managed before. After fixing minor imperfections, he took it to the fields just as pesticide season began. A villager challenged him to a “human vs. machine” spray contest. The villagers rushed to start, but once Liu’s flying umbrella took off, it sped across the fields in seconds. Soon, the tired villagers slowed down; Liu finished first. The once-doubtful crowd now cheered. Liu’s dream hadn’t disappeared — it had transformed: what started as a mere personal ambition became a tool that lightened his neighbors’ burdens. 24．Why did Liu’s family disapprove of him? A．His invention didn’t benefit villagers. B．The villagers held a doubtful attitude. C．He spent too much money and energy. D．The government objected to his vision. 25．What can we know about Liu’s pesticide-spraying flying umbrella? A．It enhanced flexibility at great heights. B．It could extend long-distance range. C．It was capable of taking off in limited spaces. D．It enlarged the capacity to store pesticides. 26．Why was a “human vs. machine” spray contest launched? A．To prove the effectiveness of the flying umbrella. B．To fix the imperfection of the flying umbrella. C．To persuade villagers to use the flying umbrella. D．To draw authority’s concern about flying umbrella. 27．What is the best title for the text? A．The Battle Between Human and Machine B．The Challenges of Building a Pesticide Aircraft C．A Village’s Battle Against Farm Work Tiredness D．A Dream Redefined: From Disapproval to Applause C It has long been assumed that identical twins, who share nearly 100% of their genetic code, would have almost identical levels of intelligence. However, a recent study challenges this assumption, revealing that even with the same genes, significant differences in IQ can exist. The research focused on a unique aspect of biology: epigenetics (表观遗传学). Epigenetics involves chemical markers that attach to DNA．These marks don’t change the DNA sequence (序列) itself, but they can turn genes “on” or “off,” influencing how they are expressed. Think of DNA as the hardware of a computer — the fixed instructions. Epigenetic marks are then like the software that decides which programs run and how they operate. Scientists studied pairs of identical twins and found that while their DNA sequences were the same, their epigenetic landscapes were not. These epigenetic differences accumulate over a person’s lifetime due to factors like unique life experiences, different diets, exposure to distinct environmental pollutants, or even varied social interactions. The study discovered a strong correlation between these different epigenetic patterns and measurable differences in the twins’ IQ scores. In some pairs, the IQ difference was as large as that typically seen between two unrelated individuals. This finding is significant because it moves the conversation beyond the classic “nature vs. nurture” debate. It suggests a more complex mechanism: genes set the potential, but life experiences write an epigenetic layer on top, which fine-tunes how that potential is realized. This understanding helps explain why one twin might develop a different cognitive ability or even more likely to develop certain mental health conditions than the other. The implications of this research extend far beyond twins. It provides a biological explanation for how our personal experiences and environment actively shape our brain’s function and cognitive abilities throughout our lives, offering a new framework for understanding human intelligence and individual differences. 28．According to the passage, what is the traditional assumption about identical twins’ IQs? A．Their IQs are shaped by their upbringing and environment. B．They often have significant differences in IQ due to different lives. C．Their intelligence levels are almost the same due to identical genes. D．Their IQ scores are not influenced by genetic factors. 29．What can be inferred from the study’s findings about intelligence? A．Genes are the only factor that determines a person’s IQ level. B．Life experiences may cause changes in a person’s DNA sequence. C．Gene expression is regulated by environmental factors. D．The cognitive differences between twins are smaller. 30．What is the author’s attitude toward the findings of this study? A．Doubtful. B．Supportive. C．Neutral. D．Disappointed. 31．Where is this passage most likely taken from? A．A personal diary. B．A non-fiction novel. C．A history textbook. D．A science news report. D During this year’s Spring Festival, Mount Taishan introduced wearable robotic exoskeletons (外骨骼) designed to assist hikers, making the demanding climbing more accessible especially for elderly and physically-challenged visitors. One 68-year-old tourist reported immediate relief from leg pain and a sensation of being assisted uphill, confirming the device’s practical effectiveness. The 1.8-kilogram exoskeleton, co-developed by the Taishan Cultural Tourism Group and Shenzhen-based Kenqing Technology, wraps around the waist and thighs (大腿). Powered by artificial intelligence, it senses the wearer’s pace and movement to provide real-time assistance, effectively reducing tiredness and joint pressure. Officials stated that the exoskeletons were introduced specifically to enable elderly visitors to experience the mountain’s natural beauty firsthand, as traditional cable cars often limit scenic immersion. This innovative application has generated broader discussions about the technology’s potential in addressing elderly care challenges within China’s rapidly aging society. The newest data reveals that by the end of 2024, China had 310 million citizens aged 60 or above, accounting for 22% of the total population. This proportion is projected to rise to 30% by 2035. Recognizing this vast market, Kenqing Technology has developed a dedicated lightweight exoskeleton system for elderly users, integrating advanced sensors and motion control to assist with walking, running, and climbing. The company plans to release an upgraded model this year, featuring lighter materials and more intelligent algorithms (算法) for better adaptability. Government policy actively encourages this sector’s development. National guidelines promote new models of intelligent health and elderly care, support the use of service robots, and foster the assistive recovery device industry. Industry experts and company executives agree that such policy support, combined with market forces, is essential to achieve large-scale adoption. They emphasize that widespread use will ultimately reduce production costs, making these assistive technologies more affordable for families across the country. 32．According to paragraph 1, what is one reported effect of using the exoskeleton? A．Complete relief from joint pain. B．Feeling of being supported upward. C．Immediate increase in hiking speed. D．Significant weight reduction for users. 33．The underlined word “immersion” in paragraph 2 refers to the experience of being ______. A．visually restricted B．financially supported C．physically surrounded D．technologically assisted 34．What is the primary reason for developing a new exoskeleton model this year? A．To better serve elderly users’ needs. B．To target younger hiking enthusiasts. C．To compete with cable car companies. D．To reduce government policy reliance. 35．What is the government’s attitude towards the future of robotic exoskeletons? A．Uncertain. B．Dismissive. C．Concerned. D．Supportive. 第二节（共5小题：每小题2. 5分, 满分12. 5分） 阅读下面短文, 从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Today, screens have become an inseparable part of human life. 36 While technology offers numerous benefits, excessive screen time can negatively impact their health. If you are parents, the following are a number of beneficial tips that can help keep your children active and healthy in the digital world. Setting very clear rules for screen time is the first step. Regardless of age, it is important for children to have consistent limits on it daily. Make sure to spell these limits out loud and clear for children, explaining to them why such limits have been set in place. 37 It is also very important to balance screen time with outdoor play and exercise. 38 As you know, interest is the best teacher. And regular exercise helps them develop the motor skills of the body, builds strength, and keeps them at a healthy weight. 39 For example, the interactive games get kids up and moving around through dancing or sports-type video games. Setting activity challenges is also helpful. During screen time, challenge your children by taking breaks and doing brief physical activities. Challenge them to ten jumping jacks, running on the spot, or stretching every 30 minutes. Many children tend to imitate(模仿)their parents’ behavior. Therefore, the first step toward developing good screen habits involves being a role model. 40 Besides, make it a point to discuss media use openly with your children to guide them effectively. A．Parents and children should establish a good relationship. B．If necessary, carry out this with the help of parental control tools. C．Separating study time from play time is the most suitable for them. D．Limit your own screen time and engage in the face-to-face interactions. E．Motivate your children to get involved in different sports that they enjoy. F．From study to play, children are increasingly exposed to electronic devices. G．Combining screen time with physical activities can help engage children more. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题：每小题1分，满分15分） 阅读下面短文, 从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。 Lila had been silent for years.

He was a quiet junior high school student. He was not an inventor, but he helped people change. He was the one who often cleaned out his family’s fridge. Every Sunday, he would find forgotten leftovers, wilted (枯萎的) vegetables, and expired yogurts that were not safe to eat. “We just bought this last week!” his mom would sigh, throwing a half-full box into the bin. The waste bothered Harry: It was like throwing money and food away straight into the trash. Then a simple idea came up to him. He began writing “EAT ME FIRST!” on sticky notes and putting them on the leftovers. It worked a little, but he still wanted a better system. For his school science project, Harry created “Keeper Tags.” They were simple, colorful magnetic tags with a dial (转盘) you could turn. Each tag had three colored parts: Green (Fresh!) , Yellow (Eat Soon!) , and Red (Last Call!) . When you put food in the fridge, you clipped a tag to it, turned the dial to green, and wrote the food’s name. After a few days, you turned the dial to yellow, then to red. Soon, the fridge door was full of bright colors that showed what to eat first. Harry tested the tags in his house for a month. Their food waste dropped by nearly70%. All his family loved the colourful reminder. It even became a game for his 5-year-old little sister to check the tags. Harry’s teacher encouraged him to share the idea online. He posted a short video explaining the problem and his simple solution. 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。 The response was unexpected. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Before long, many families began using their own Keeper Tags. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 原创精品资源学科网独家享有版权，侵权必究！1 4 / 12 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ 2025-2026学年高二英语选择性必修第三册单元自测（四川专用） Unit 5·培优卷（参考答案） 题号 1 2 3 4 5 6 7 8 9 10 答案 B C C A B B A B C B 题号 11 12 13 14 15 16 17 18 19 20 答案 C A B A B C C A B A 题号 21 22 23 24 25 26 27 28 29 30 答案 C B B C C A D C C B 题号 31 32 33 34 35 36 37 38 39 40 答案 D B C A D F B E G D 题号 41 42 43 44 45 46 47 48 49 50 答案 D A C A B B C D A C 题号 51 52 53 54 55 答案 D C B B A 56．which 57．extracted 58．dramatically 59．against 60．burial 61．to be completed 62．has been strengthened 63．Having achieved 64．but 65．valuable 66．参考范文： Science and Technology Change Life The rise of smart home devices is a vivid example of how technology reshapes daily life. In my home, we have installed voice-controlled lights that adjust brightness and color automatically. This innovation has influenced me significantly. Primarily, it has fostered environmental awareness. By optimizing energy use, I have become more conscious of sustainable living. Furthermore, it has enhanced family time. Instead of manually adjusting lamps, we now have more leisure moments together in comfortably lit spaces. I’ve learned to manage it as a practical tool for efficiency, not entertainment, ensuring it serves rather than distracts from real-life interactions. 67． The response was unexpected. The video quickly went viral, attracting attention from all corners. People were impressed by Harry’s simple yet effective solution to the common problem of food waste. Messages of praise and support flooded in, with many expressing their eagerness to try out the Keeper Tags in their own homes. Some even suggested improvements or offered to help spread the idea further. Harry was overwhelmed by the positive feedback, feeling a sense of accomplishment he had never experienced before.   Before long, many families began using their own Keeper Tags. The colorful magnetic tags became a popular sight in fridges across the neighborhood and even beyond. Stores started selling similar products inspired by Harry’s invention, and he was invited to share his story on local TV shows and in newspapers. More importantly, the amount of food waste in these families significantly decreased, just like in Harry's home. Harry’s simple idea had sparked a movement, proving that even a small change could make a big difference in the world. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司2 / 2 学科网（北京）股份有限公司 $
