He also expressed a desire to see more effective and adaptable desertification control technologies shared globally through initiatives, such as China’s Belt and Road Initiative and the Global Development Initiative. ⑳Inger Andersen, executive director of the UNEP, said the accomplishments of the 2024 Champions of the Earth Award winners remind human beings that the fight to protect vital ecosystems, such as land, rivers and oceans, is achievable. 第二部分 阅读（共两节，满分50分） 第一节 （共15小题；每小题2.5分，满分37.5分） 阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。 A Many inventors have left their marks on history in their own ways. Although there are inventors who you might not know, that doesn’t mean their contributions to science are less significant. Keep reading to learn about some famous inventors. John Deere John Deere is best known for being an inventor in the agricultural space. When the blacksmith noticed he was often making the same repairs to wood and cast-iron plows used by farmers, he began experimenting with more durable plow designs, which he then sold to local farmers. His steel plows exploded in popularity among many farmers, with Deere’s company (also called John Deere) producing 1,600 plows in 1850. That same year, the company started producing other tools in addition to plows. Charles Babbage If you’re reading this on a computer, you have mathematician and inventor Charles Babbage to thank. Although he didn’t invent the computer as we know it today, his ideas laid the groundwork for modern computers. Because of this, he’s often referred to as “the father of computing”. Steve Jobs Along with Steve Wozniak, Steve Jobs was an inventor behind Apple Computers. As the now-famous story goes, Jobs and Wozniak started Apple Computers in Jobs’ family’s garage in 1976, and the work they did there made computers more accessible and more affordable for consumers. Jobs left Apple in 1985, but he returned in 1997 and revitalized the company, leading to the creation of products like the iPod and iPhone. Joy Mangano If you’ve ever used a Miracle Mop, you have Joy Mangano to thank. The 67-year-old created the innovative cleaning tool in 1990, which she marketed and sold herself. A couple of years after inventing the device, she appeared on QVC to sell it, where more than 18,000 mops were sold within a half hour. In addition to the Miracle Mop, Mangano is the creator of Rolykit, Huggable Hangers, and Forever Fragrant. 1．What inspired John Deere to invent steel plows? A．His eagerness to earn money. B．His dream of becoming an inventor. C．The frequent repairs that he had to make. D．The high price of the wood and cast-iron plows. 2．Why do people refer to Charles Babbage as “the father of computing”? A．He invented the computer. B．He formed the basis for modern computers. C．He was a great mathematician and inventor. D．He was the person who first had the idea of reading on a computer. 3．Who made it easier for busy parents to keep the house clean? A．John Deere. B．Charles Babbage. C．Steve Jobs. D．Joy Mangano. 【答案】1．C 2．B 3．D 【导语】这是一篇说明文。文章介绍了4位著名发明家的事迹。 【详解】1．细节理解题。由John Deere中“When the blacksmith noticed he was often making the same repairs to wood and cast-iron plows used by farmers, he began experimenting with more durable plow designs, which he then sold to local farmers. (当这位铁匠注意到他经常对农民使用的木制和铸铁犁进行同样的维修时，他开始试验更耐用的犁设计，然后卖给当地农民)”可知，不得不经常修理木制和铸铁犁激发了John Deere发明钢犁。故选C项。 2．细节理解题。由Charles Babbage中“Although he didn’t invent the computer as we know it today, his ideas laid the groundwork for modern computers. Because of this, he’s often referred to as “the father of computing”. (尽管他没有发明我们今天所知的计算机，但他的想法为现代计算机奠定了基础。正因为如此，他经常被称为“计算机之父”)”可知，Charles Babbage被称为“计算机之父”是因为他奠定了现代计算机的基础。故选B项。 3．细节理解题。由Joy Mangano中“If you’ve ever used a Miracle Mop, you have Joy Mangano to thank. The 67-year-old created the innovative cleaning tool in 1990, which she marketed and sold herself. (如果你曾经使用过奇迹拖把，那就要感谢Joy Mangano。这位67岁的女士于1990年发明了这种创新的清洁工具，并将其推向市场并出售)”可知，发明奇迹拖把的Joy Mangano让忙碌的父母更容易保持家里的清洁。故选D项。 B In December 2025, Australia will make history as the first country to ban children under 16 from using social media platforms (平台) like Meta, X, and TikTok. This groundbreaking policy has led to heated global discussion, making Australia a test case for solving one of today’s trickiest youth problems. The Australian government, led by Prime Minister Anthony Albanese, says the ban is a necessary response to a growing public health problem. Many studies link too much social media use among young people to higher rates of depression, self-harm, and addiction. Beyond that, the platforms’ design causes other risks like self-worth damaging. Albanese said, “Social media are doing social harm to our kids. We’ve reduced time on it. We want our kids to have a childhood.” However, experts raise serious concerns. Teens who are skilled in technology might use VPNs to avoid the ban, pushing them to less safe parts of the internet. Overly strict selection could also prevent them from using valuable learning resources and social connections, especially for marginalized (被边缘化的) youth or kids from other regions seeking real community. Social media companies like Meta and TikTok have blamed the policy, noting they already offer age-suitable safety features. Globally, other Western nations have taken different approaches. The EU uses rules to force tech companies to be more serious, while U.S. efforts aren’t worth mentioning—federal (联邦的) action is prevented by free speech debates, and states have different bans. As a medium-sized market, Australia’s policy results will offer important lessons for other countries. If the ban improves teens’ mental health without creating unlawful digital markets or separating weak groups, it could become a global model. If it fails, it will serve as a warning about the limits of government control in the borderless digital world. All eyes are on Australia to see how this brave experiment carries on. 4. Why did Australia introduce the social media ban for under-16s? A. To respond to the overuse of social media. B. To promote local social media platforms. C. To offer teens more online learning resources. D. To limit tech companies’ influence on Australia. 5. What is the experts’ attitude towards Australia’s ban? A. Positive. B. Unclear. C. Worried. D. Disappointed. 6. What may make Australia’s ban successful? A. Young people give up using the internet. B. Other countries copy the policy immediately. C. Tech companies stop updating social media platforms. D. Australia improves teens’ mental health without side effects. 7. What is the best title for the text? A. Tell Differences of Social Media Rules B. Australia’s Under-16 Social Media Ban C. Australia’s Social Media Policy History D. Protect Youth from Today’s Social Media 【答案】4. A 5. C 6. D 7. B 【导语】文章主要介绍澳大利亚出台政策禁止16岁以下青少年使用社交媒体，阐述政策出台缘由、专家担忧、各国不同管控方式，以及该政策试行结果带来的参考意义。 【详解】4. 细节理解题。根据原文第二段“The Australian government, led by Prime Minister Anthony Albanese, says the ban is a necessary response to a growing public health problem.(由Anthony Albanese总理领导的澳大利亚政府表示，这项禁令是应对日益严峻的公共健康问题的必要举措。)”及“Albanese said, “Social media are doing social harm to our kids. We’ve reduced time on it. We want our kids to have a childhood.”(Albanese称：“社交媒体正对孩子造成社会伤害。我们减少了孩子的上网时长，想让他们拥有真正的童年。”)”可知，出台禁令是为应对青少年过度使用社交媒体带来的问题。 5. 推理判断题。根据原文第三段“However, experts raise serious concerns.(然而，专家们对此提出了诸多担忧。)”可知，专家对这项禁令持担忧的态度。 6. 细节理解题。根据原文最后一段“If the ban improves teens’ mental health without creating unlawful digital markets or separating weak groups, it could become a global model.(如果该禁令能够改善青少年的心理健康，且不会催生非法数字市场、不会孤立弱势群体，它就有望成为全球典范。)”可知，无副作用地改善青少年心理健康能够让禁令取得成效。 7. 主旨大意题。根据原文第一段“In December 2025, Australia will make history as the first country to ban children under 16 from using social media platforms (平台) like Meta, X, and TikTok.(2025年12月，澳大利亚将创下历史，成为首个禁止16岁以下儿童使用脸书、推特、抖音等社交媒体平台的国家。)”及全文内容可知，全文围绕澳大利亚针对16岁以下人群的社交媒体禁令展开论述，介绍背景、争议与影响，可知文章最佳标题为：澳大利亚16岁以下人群社交媒体禁令。 C On first impression, Zhang Xue doesn’t seem to care whether people like him. But behind his rough appearance lies a story of adversity and courage. Zhang Xue, now 39, is the founder of ZXMOTO, a Chinese motorcycle brand that recently made history by winning two World Supersport races in Portugal. Few people know that his journey to success was filled with setbacks. Growing up in a poor family in Hunan, Zhang had to drop out of school at an early age. He became an apprentice in a small repair shop, working long hours for little pay. Many people laughed at his dream of building a high-performance Chinese motorcycle. “You’re just a repairman,” they said. “You’ll never make it.” But Zhang refused to give up. He spent his savings on second-hand books and taught himself engineering at night. When he finally started his own company in 2024, he faced even greater challenges. Foreign suppliers refused to sell him key parts, hoping to keep their technological advantage. Instead of backing down, Zhang decided to develop his own engine. “There were times when I wanted to quit,” Zhang admits. “But every time I thought about my dream, I found the courage to keep going.” After countless failures and sleepless nights, his team overcame one technical problem after another. They developed an independent engine that could compete with the world’s best. His perseverance paid off. In March 2026, ZXMOTO’s 820RR-RS bike won two World Supersport races, beating giants like Ducati and Yamaha. Zhang’s story has inspired millions of young people in China. “If you have a dream,” he says, “don’t let anyone tell you it’s impossible. Adversity only makes you stronger.” 8. What can we learn about Zhang Xue’s early life? A. He was born into a wealthy family. B. He received a formal engineering education. C. He faced poverty and lack of support. D. He was a professional racer from the start. 9. How did Zhang Xue respond when foreign suppliers refused to sell him parts? A. He decided to develop his own engine. B. He gave up his dream. C. He borrowed money to buy from others. D. He moved his company to another country. 10. The underlined word “perseverance” in Paragraph 6 is closest in meaning to ________. A. talent and luck B. continued effort despite difficulties C. wealth and fame D. natural ability without practice 11. What is the main message of Zhang Xue’s story? A. Success comes only to those with a good education. B. Foreign technology is necessary for success. C. Wealth is the most important thing in life. D. Adversity and courage can lead to great achievements. 【答案】8. C 9. A 10. B 11. D 【导语】本文讲述了中国摩托车品牌ZXMOTO创始人张雪从贫困少年到自主研发发动机、最终在世界超级摩托车锦标赛中击败杜卡迪和雅马哈等国际巨头的励志故事。 【详解】8. 细节理解题。根据第三段“Growing up in a poor family in Hunan, Zhang had to drop out of school at an early age. He became an apprentice in a small repair shop, working long hours for little pay. Many people laughed at his dream of building a high-performance Chinese motorcycle.(张雪出身湖南贫困家庭，年少便被迫辍学。他进入一家小型维修店当学徒，整日辛劳却收入微薄。不少人都嘲笑他立志打造国产高性能摩托车的梦想。)”可知，张雪出身贫寒且得不到支持。 9. 细节理解题。根据第四段“Foreign suppliers refused to sell him key parts, hoping to keep their technological advantage. Instead of backing down, Zhang decided to develop his own engine.(国外供应商拒绝向他出售核心零部件，企图守住自身技术优势。但他并未退缩，转而决心自主研发发动机。)”可知，当外国供应商拒绝出售零件时，张雪的回应是决定自主研发发动机。 10. 词句猜测题。根据上文“After countless failures and sleepless nights, his team overcame one technical problem after another. They developed an independent engine that could compete with the world’s best.(历经无数次失败与无数个不眠之夜，团队接连攻克一道道技术难关，成功研发出可媲美世界顶尖水准的自研发动机。)”可知，张雪和他的团队在困难中持续努力。由此可知，perseverance意为“在困难中持续努力，坚持不懈”。 11. 主旨大意题。根据第一段“But behind his rough appearance lies a story of adversity and courage.(但粗犷外表之下，藏着一段历经磨难、满怀勇气的人生故事。)”和最后一段“Adversity only makes you stronger.(逆境只会让人愈发强大。)”可知，全文围绕张雪如何面对贫困、嘲笑、技术封锁等逆境，凭借勇气和毅力最终成功。由此可知，选项D“逆境与勇气可以带来伟大成就。”完整概括了故事的核心信息。 D In your morning rush to get ready, you brush your teeth, head to the kitchen, and drink a big glass of orange juice—yuck! What makes your clean mouth taste bitter when it meets orange juice? Thanks to evolution, your brain is designed to make you love the sweetness of sugars that your body needs for energy and hate the bitterness of many poisonous things in nature that could kill you. Your awareness of these two particular tastes is significant for your survival. In your body, every cell is held together by a membrane (膜), which is mostly made up of fats. For the cells in your mouth that are responsible for taste, their membranes have something extra called G protein-coupled receptors (GPCR, G 蛋白偶联受体). Some of these GPCRs are designed to react to sweet tastes while others are sensitive to bitter tastes, acting as an alarm system. Toothpaste typically contains sodium lauryl sulfate (SLS, 十二烷基硫酸钠). It is a type of detergent (洗涤剂) that helps remove the film of germs on your teeth, so your breath does not smell bad. Similar to how detergent breaks up fat in oily water, SLS can break down the fats in the membranes of your taste cells. As a result, your sense of taste changes for a while. But why does orange juice specifically become bitter instead of developing a different taste? The answer lies in the citric acid (柠檬酸) in the juice. In our study, seven volunteers tasted sugar, citric acid, salt and a bitter medicine. Both before and after the tasting, they held a solution of SLS in their mouths for one minute. The result showed that the tastes of sugar, salt and the medicine were reduced, but for citric acid, a bitter taste was added. 12. How does the author introduce the topic of the text? A. By explaining a biological rule. B. By presenting a research result. C. By suggesting a healthy breakfast habit. D. By describing a common daily experience. 13. What is the main function of GPCRs in taste cell membranes? A. To produce taste cell membranes. B. To react specifically to sweet and bitter tastes. C. To help remove germs from teeth. D. To improve the taste of foods and drinks. 14. How does sodium lauryl sulfate in toothpaste affect taste cells? A. It makes them more active. B. It forms a protective layer on them. C. It acts on the fats in their membranes. D. It makes them more sensitive to sourness. 15. What did the experiment in the last paragraph find about SLS? A. Its effects on taste last for several hours. B. It causes citric acid to taste bitter C. It enhances the taste of salt D. It makes medicine taste sweeter. 【答案】12. D 13. B 14. C 15. B 【导语】文章主要讲解刷牙后喝橙汁口感发苦的原理，从味觉受体、牙膏成分作用以及相关实验展开科学解释。 【详解】12. 推理判断题。根据第一段“In your morning rush to get ready, you brush your teeth, head to the kitchen, and drink a big glass of orange juice—yuck! What makes your clean mouth taste bitter when it meets orange juice?(清晨匆忙洗漱时，你刷完牙走到厨房喝下一大杯橙汁，口感却十分糟糕。为何清爽的口腔接触橙汁后会泛起苦味呢？)” 可知，作者通过描述日常常见经历引出文章话题。 13. 细节理解题。根据第三段“Some of these GPCRs are designed to react to sweet tastes while others are sensitive to bitter tastes, acting as an alarm system.(部分G蛋白偶联受体专门感知甜味，其余的则对苦味敏感，起到警报系统的作用。)” 可知，G蛋白偶联受体可针对性感应甜味与苦味。 14. 细节理解题。根据第四段 “SLS can break down the fats in the membranes of your taste cells.(十二烷基硫酸钠会分解味觉细胞膜中的脂肪物质。)”可知，该物质会作用于味觉细胞膜内的脂肪。 15. 细节理解题。根据最后一段“The result showed that the tastes of sugar, salt and the medicine were reduced, but for citric acid, a bitter taste was added.(实验结果显示，糖分、盐分和药物的味道都会变淡，而柠檬酸则会生出苦味。)”可知，十二烷基硫酸钠会让柠檬酸尝起来带有苦味。 第二节（共5小题：每小题2. 5分, 满分12. 5分） Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维). 16 As a result, a used water bottle can take on a new life as activewear or even high-fashion pieces. 17 First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance. Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin. 18 According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022. This growth comes from rising awareness of both its practical advantages and its environmental value. In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear. 19 Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket. 20 rPET is not a perfect solution to plastic pollution, but it is a meaningful step toward more sustainable fashion and a cleaner planet. A．It is also lightweight and wrinkle-resistant. B．However, market trends tell a different story. C．The transformation happens through several steps. D．This keeps millions of plastic bottles out of landfills each year. E．Recycling rPET fabric back into new fabric can be challenging. F．While it is safe to wear, it releases microplastics when it is washed. G．Unlike traditional polyester made from petrol, rPET uses existing plastic. 【答案】16．G 17．C 18．B 19．A 0．D 【导语】本文主要介绍再生聚酯纤维rPET，讲解其原料来源、制作流程、市场发展、性能优势与环保价值，指出它虽不完美，但助力可持续时尚发展。 【详解】16．根据上文“Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维).(你知道吗，你时尚的夹克或最喜欢的牛仔裤可能曾经是塑料瓶？这就是rPET的世界，也被称为再生聚酯纤维。)”以及下文“As a result, a used water bottle can take on a new life as activewear or even high - fashion pieces.(因此，一个用过的水瓶可以以运动服甚至高级时装的形式获得新生。)”可知，空格处需介绍rPET 的原料特点。G选项“Unlike traditional polyester made from petrol, rPET uses existing plastic.(与由石油制成的传统聚酯纤维不同，rPET使用现有的塑料。)”符合语境，承接上文对rPET的介绍，引出下文用过的水瓶能获得新生的内容。 17．根据下文“First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance.(首先，收集、分类和清洁塑料瓶。清洁后，将它们切割、熔化成液体，并拉伸成细纤维。然后，这些纤维被纺成纱线，可以编织成不同种类的织物。最后，织物经过印刷或涂层等整理工序，以达到所需的颜色、图案和性能。)”可知，此段主要介绍了塑料瓶变成rPET面料的过程，即通过几个步骤实现转变。C选项“The transformation happens through several steps.(这种转变通过几个步骤发生。)”符合语境，引出下文对具体步骤的介绍。 18．根据上文“Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin.(有些人认为用“废物”制成的衣服一定很便宜或质量低劣。的确，基于塑料的面料透气性可能较差，对敏感皮肤的人来说可能会感觉粗糙。)”以及下文“According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022.(根据纺织品交易所的一份报告，2020年至2021年间，rPET的使用量增长了20%，2022年占全球聚酯纤维总产量的约14%。)”可知，上文提到有些人对rPET制成的衣服有负面看法，下文却表明rPET的使用量在增长，前后内容存在转折关系。B选项“However, market trends tell a different story.(然而，市场趋势却讲述了另一个故事。)”转折过渡，说明市场情况与人们想法不同。 19．根据上文“In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear.(在性能方面，rPET坚固、耐用且速干，这些特性使其成为运动服装的理想选择。)”可知，此段在介绍rPET的性能优势，此处应继续说明其其他性能优势。A选项“It is also lightweight and wrinkle - resistant.(它还重量轻且抗皱。)”用并列结构补充其性能优势，与上文内容衔接紧密。 20．根据上文“Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket.(除了性能之外，rPET还有利于环境。与传统聚酯纤维的生产相比，它的生产用水量减少了99%，这对参与纺织制造的水资源紧张地区来说是一个重要好处。它还有助于减少浪费。大约25个rPET瓶子可以制成一件夹克的纤维。)”可知，此段在介绍rPET的环保价值，空格处需说明该做法的环保成效。D选项“This keeps millions of plastic bottles out of landfills each year.(这每年使数百万个塑料瓶远离垃圾填埋场。)”承接上文减少浪费的内容，具体体现 rPET的环保价值，符合语境。 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。 I used to hate running.

He met Xiao Kong on his way to the Temple of Confucius, who was going there 1 (meet) her study group. The two teenagers soon started a warm conversation about the local history and traditions. Xiao Kong introduced that the temple 2 (build) in 478 BC to honor Confucius, a great educator and thinker. Confucius is also recognized as 3 great philosopher whose ideas have been 4 (wide) spread across the world. His teachings 5 (shape) Chinese culture for centuries and are still influencing people’s lives now. As they walked through the courtyard 6 (surround) by ancient cypresses, Xiao Kong explained Confucius’ ideas about “benevolence” and “propriety”. She mentioned that Confucius believed every individual should treat others with respect. 7 is interesting to note that Confucius has millions of 8 (descendant) around the world, and many of them still follow his philosophical principles. When asked about her favorite Confucian saying, Xiao Kong quoted a classic one, 9 (say) it reminds her to keep learning and reflecting. William nodded and said he now understands why Qufu is such a special place—it’s not just about historic sites, but about the living traditions 10 connect people to the past. 【答案】 1. to meet 2. was built 3. a 4. widely 5. have shaped 6. surrounded 7. It 8. descendants 9. saying 10. that/which 【导语】文章主要讲述英国学生威廉游览孔子故里曲阜时，偶遇小孔并一同交流孔子及其思想、相关古迹与儒家文化的经历。 【详解】1. 考查非谓语动词。句意：他在前往孔庙的路上遇到了小孔，小孔正要去那里和她的学习小组碰面。此处为非谓语动词作状语，说明前往孔庙的目的，所以用动词不定式形式to meet作目的状语。 2. 考查语态。句意：小孔介绍说，这座庙宇建于公元前478年，用以纪念伟大的教育家和思想家孔子。此处为谓语动词，时间状语“in 478 BC”表示过去，用一般过去时，主语the temple与build之间为被动关系，所以用一般过去时的被动语态，且主语为第三人称单数，所以谓语动词为was built。 3. 考查冠词。句意：孔子也被公认为一位伟大的哲学家，他的思想在全世界广泛传播。philosopher为可数名词单数，空前无限定词，结合句意，此处泛指“一位伟大的哲学家”，且great是以辅音音素开头的单词，所以用不定冠词a。 4. 考查副词。句意：孔子也被公认为一位伟大的哲学家，他的思想在全世界广泛传播。此处修饰动词spread，需用副词作状语，wide的副词形式为widely译为“广泛地”。 5. 考查时态。句意：数百年来，他的学说塑造了中国文化，如今依旧影响着人们的生活。此处为谓语动词，根据时间状语“for centuries”可知，此处强调从过去持续到现在的动作，要用现在完成时，其结构为“have/has +过去分词”，主语His teachings为复数，所以谓语动词为have shaped。 6. 考查非谓语动词。句意：当他们穿行在被古柏环绕的庭院中时，小孔讲解了孔子关于“仁”与“礼”的思想。此处为非谓语动词作后置定语，the courtyard与surround之间为被动关系，所以用过去分词surrounded。 7. 考查代词。句意：有趣的是，孔子在全球拥有数百万后裔，其中许多人依旧恪守他的哲学理念。此处为“it is+adj.+to do sth.”结构，其中it作形式主语，真正的主语为后面的不定式短语，所以此处为代词it，位于句首，首字母需大写。 8. 考查名词复数。句意：有趣的是，孔子在全球拥有数百万后裔，其中许多人依旧恪守他的哲学理念。descendant为可数名词，前面有millions of修饰，表示数百万后裔，需用复数形式descendants。 9. 考查非谓语动词。句意：当被问及最喜欢的儒家名言时，小孔引用了一句经典话语，并表示这句话提醒自己不断学习和自省。此处为非谓语动词作伴随状语，say与逻辑主语Xiao Kong之间是主动关系，所以用现在分词saying。 10. 考查定语从句。句意：威廉点了点头，说他如今明白了曲阜为何如此特别，这里不仅有古迹，还有传承至今、连接古今的鲜活传统。此处引导定语从句，先行词为traditions，指代事物，从句中缺少主语，所以用关系代词that或which。 第四部分 写作（共两节, 满分40分） 第一节（满分15分） 假如你是李华，你校英语公众号将推出以“科技”为主题的系列推送。请你用英文给公众号留言，介绍一个你认为最实用的设备（device）或应用程序（app），并描述它给生活带来的便利。 提示词语：technology, communicate, learn, convenient, time-saving 提示问题： ●  What device or app do you want to introduce? ●  What benefits does it bring to people?

It was May, yet we walked up a snow-covered hill. When we noticed our jeans were wet up to our knees, it did not dampen our spirits Not once did we say, “Let’s turn around.” This was our vacation, and we were on an adventure. Little did we know this was the beginning of many more surprises. The trail was marked as an easy one-kilometer like yet we were already walking a long distance. Our light-heartedness stopped when we came out into a clearing and saw a parking lot without our rental car in it. As my eyes scanned the surroundings, nothing looked familiar. My heart raced. I realized we were lost in a national park that did not officially open for another week. Usually, I am the calm one in the relationship, but my husband surprised me with his calmness. This did not comfort me; in fact, it heightened my fear. As we walked, I asked my husband to call for help, but there was no cell-phone signal in this isolated（偏僻的）area. It was awfully quiet except for our footsteps hitting the road, and my heavy breathing. My husband suggested we conserve energy and walk slower. With each step on the road, my feet and thighs hurt while my mind raced with thoughts about people who got lost in the Canadian woods for days. My vision sharpened. I noticed everything around me: the trees, rocks and snow. I thought we could eat the snow on the ground in case we needed water. For the first time in my life, I was ready and willing to get a ride, but we did not meet with a single car on the road. Silently, I prayed multiple times. We focused on each other, made joint decisions and connected through gratitude. We managed to stay on the main road and walked straight on. Paragraph 1: My husband suddenly spotted a small building on a hill in the distance. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Paragraph 2: Just then, a friendly woman appeared, saying, “Hello.” __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 【答案】One possible version Paragraph 1 My husband suddenly spotted a small building on a hill in the distance. In no time we found ourselves heading for it. We were filled with hope and excitement to find such a building in the middle of nowhere. We climbed up the hill at a swinging pace as if all the pains were gone. As we approached, a sign came into sight, which read: Administration Office. However, it was not open for business. The empty hall made us nervous all at once. We stood there hopelessly, wondering what to do next. Paragraph 2： Just then, a friendly woman appeared, saying, “Hello.” I could barely hold back my enthusiasm and blurted out, “Were lost!” She comforted us and opened a room for us to take a break. Seeing we were cold and hungry, she treated us with hot chocolate. After studying the map, we figured out that our car was parked over three kilometers away. She offered us a ride back to our car and we accepted gladly. I felt relieved to see our rental car again. What a blessing to have such an unforgettable experience 【分析】本文以人物为线索展开，作者和丈夫正深入森林深处探险，这时，他们注意到租的车看不见了，意识到在森林里迷路之后，作者变得非常紧张，但他们只能保持镇定，继续行走在主干道上，希望遇到过路的车辆或行人以便求助。 【详解】1.段落续写： ①由第一段首句内容“我丈夫突然发现远处山上有一座小建筑。”可知，第一段可描写作者和丈夫满怀希望地奔向那座小建筑的情形。 ②由第二段首句内容“就在这时，一位友善的女士出现了，她说：你好。”可知，第二段可描写作者和丈夫得到这位善良女士的帮助，最终找到租的车并脱险。 2.续写线索：发现小建筑——欣喜赶到——无人回应——出现女士——提供帮助——安全返回 3.词汇激活 行为类 ①前往：head for/proceed to ②脱口而出：blurt out/plump out ③发现：make out/spot 情绪类 ①激动：thrilled/excited ②感谢：show one’s gratitude/be grateful 【点睛】[高分句型1].

Although there are inventors who you might not know, that doesn’t mean their contributions to science are less significant. Keep reading to learn about some famous inventors. John Deere John Deere is best known for being an inventor in the agricultural space. When the blacksmith noticed he was often making the same repairs to wood and cast-iron plows used by farmers, he began experimenting with more durable plow designs, which he then sold to local farmers. His steel plows exploded in popularity among many farmers, with Deere’s company (also called John Deere) producing 1,600 plows in 1850. That same year, the company started producing other tools in addition to plows. Charles Babbage If you’re reading this on a computer, you have mathematician and inventor Charles Babbage to thank. Although he didn’t invent the computer as we know it today, his ideas laid the groundwork for modern computers. Because of this, he’s often referred to as “the father of computing”. Steve Jobs Along with Steve Wozniak, Steve Jobs was an inventor behind Apple Computers. As the now-famous story goes, Jobs and Wozniak started Apple Computers in Jobs’ family’s garage in 1976, and the work they did there made computers more accessible and more affordable for consumers. Jobs left Apple in 1985, but he returned in 1997 and revitalized the company, leading to the creation of products like the iPod and iPhone. Joy Mangano If you’ve ever used a Miracle Mop, you have Joy Mangano to thank. The 67-year-old created the innovative cleaning tool in 1990, which she marketed and sold herself. A couple of years after inventing the device, she appeared on QVC to sell it, where more than 18,000 mops were sold within a half hour. In addition to the Miracle Mop, Mangano is the creator of Rolykit, Huggable Hangers, and Forever Fragrant. 1．What inspired John Deere to invent steel plows? A．His eagerness to earn money. B．His dream of becoming an inventor. C．The frequent repairs that he had to make. D．The high price of the wood and cast-iron plows. 2．Why do people refer to Charles Babbage as “the father of computing”? A．He invented the computer. B．He formed the basis for modern computers. C．He was a great mathematician and inventor. D．He was the person who first had the idea of reading on a computer. 3．Who made it easier for busy parents to keep the house clean? A．John Deere. B．Charles Babbage. C．Steve Jobs. D．Joy Mangano. B In December 2025, Australia will make history as the first country to ban children under 16 from using social media platforms (平台) like Meta, X, and TikTok. This groundbreaking policy has led to heated global discussion, making Australia a test case for solving one of today’s trickiest youth problems. The Australian government, led by Prime Minister Anthony Albanese, says the ban is a necessary response to a growing public health problem. Many studies link too much social media use among young people to higher rates of depression, self-harm, and addiction. Beyond that, the platforms’ design causes other risks like self-worth damaging. Albanese said, “Social media are doing social harm to our kids. We’ve reduced time on it. We want our kids to have a childhood.” However, experts raise serious concerns. Teens who are skilled in technology might use VPNs to avoid the ban, pushing them to less safe parts of the internet. Overly strict selection could also prevent them from using valuable learning resources and social connections, especially for marginalized (被边缘化的) youth or kids from other regions seeking real community. Social media companies like Meta and TikTok have blamed the policy, noting they already offer age-suitable safety features. Globally, other Western nations have taken different approaches. The EU uses rules to force tech companies to be more serious, while U.S. efforts aren’t worth mentioning—federal (联邦的) action is prevented by free speech debates, and states have different bans. As a medium-sized market, Australia’s policy results will offer important lessons for other countries. If the ban improves teens’ mental health without creating unlawful digital markets or separating weak groups, it could become a global model. If it fails, it will serve as a warning about the limits of government control in the borderless digital world. All eyes are on Australia to see how this brave experiment carries on. 4. Why did Australia introduce the social media ban for under-16s? A. To respond to the overuse of social media. B. To promote local social media platforms. C. To offer teens more online learning resources. D. To limit tech companies’ influence on Australia. 5. What is the experts’ attitude towards Australia’s ban? A. Positive. B. Unclear. C. Worried. D. Disappointed. 6. What may make Australia’s ban successful? A. Young people give up using the internet. B. Other countries copy the policy immediately. C. Tech companies stop updating social media platforms. D. Australia improves teens’ mental health without side effects. 7. What is the best title for the text? A. Tell Differences of Social Media Rules B. Australia’s Under-16 Social Media Ban C. Australia’s Social Media Policy History D. Protect Youth from Today’s Social Media C On first impression, Zhang Xue doesn’t seem to care whether people like him. But behind his rough appearance lies a story of adversity and courage. Zhang Xue, now 39, is the founder of ZXMOTO, a Chinese motorcycle brand that recently made history by winning two World Supersport races in Portugal. Few people know that his journey to success was filled with setbacks. Growing up in a poor family in Hunan, Zhang had to drop out of school at an early age. He became an apprentice in a small repair shop, working long hours for little pay. Many people laughed at his dream of building a high-performance Chinese motorcycle. “You’re just a repairman,” they said. “You’ll never make it.” But Zhang refused to give up. He spent his savings on second-hand books and taught himself engineering at night. When he finally started his own company in 2024, he faced even greater challenges. Foreign suppliers refused to sell him key parts, hoping to keep their technological advantage. Instead of backing down, Zhang decided to develop his own engine. “There were times when I wanted to quit,” Zhang admits. “But every time I thought about my dream, I found the courage to keep going.” After countless failures and sleepless nights, his team overcame one technical problem after another. They developed an independent engine that could compete with the world’s best. His perseverance paid off. In March 2026, ZXMOTO’s 820RR-RS bike won two World Supersport races, beating giants like Ducati and Yamaha. Zhang’s story has inspired millions of young people in China. “If you have a dream,” he says, “don’t let anyone tell you it’s impossible. Adversity only makes you stronger.” 8 .What can we learn about Zhang Xue’s early life? A. He was born into a wealthy family. B. He received a formal engineering education. C. He faced poverty and lack of support. D. He was a professional racer from the start. 9. How did Zhang Xue respond when foreign suppliers refused to sell him parts? A. He decided to develop his own engine. B. He gave up his dream. C. He borrowed money to buy from others. D. He moved his company to another country. 10. The underlined word “perseverance” in Paragraph 6 is closest in meaning to ________. A. talent and luck B. continued effort despite difficulties C. wealth and fame D. natural ability without practice 11. What is the main message of Zhang Xue’s story? A. Success comes only to those with a good education. B. Foreign technology is necessary for success. C. Wealth is the most important thing in life. D. Adversity and courage can lead to great achievements. D In your morning rush to get ready, you brush your teeth, head to the kitchen, and drink a big glass of orange juice—yuck! What makes your clean mouth taste bitter when it meets orange juice? Thanks to evolution, your brain is designed to make you love the sweetness of sugars that your body needs for energy and hate the bitterness of many poisonous things in nature that could kill you. Your awareness of these two particular tastes is significant for your survival. In your body, every cell is held together by a membrane (膜), which is mostly made up of fats. For the cells in your mouth that are responsible for taste, their membranes have something extra called G protein-coupled receptors (GPCR, G 蛋白偶联受体). Some of these GPCRs are designed to react to sweet tastes while others are sensitive to bitter tastes, acting as an alarm system. Toothpaste typically contains sodium lauryl sulfate (SLS, 十二烷基硫酸钠). It is a type of detergent (洗涤剂) that helps remove the film of germs on your teeth, so your breath does not smell bad. Similar to how detergent breaks up fat in oily water, SLS can break down the fats in the membranes of your taste cells. As a result, your sense of taste changes for a while. But why does orange juice specifically become bitter instead of developing a different taste? The answer lies in the citric acid (柠檬酸) in the juice. In our study, seven volunteers tasted sugar, citric acid, salt and a bitter medicine. Both before and after the tasting, they held a solution of SLS in their mouths for one minute. The result showed that the tastes of sugar, salt and the medicine were reduced, but for citric acid, a bitter taste was added. 12. How does the author introduce the topic of the text? A. By explaining a biological rule. B. By presenting a research result. C. By suggesting a healthy breakfast habit. D. By describing a common daily experience. 13. What is the main function of GPCRs in taste cell membranes? A. To produce taste cell membranes. B. To react specifically to sweet and bitter tastes. C. To help remove germs from teeth. D. To improve the taste of foods and drinks. 14. How does sodium lauryl sulfate in toothpaste affect taste cells? A. It makes them more active. B. It forms a protective layer on them. C. It acts on the fats in their membranes. D. It makes them more sensitive to sourness. 15. What did the experiment in the last paragraph find about SLS? A. Its effects on taste last for several hours. B. It causes citric acid to taste bitter C. It enhances the taste of salt D. It makes medicine taste sweeter. 第二节（共5小题：每小题2. 5分, 满分12. 5分） Did you know that your stylish jacket or favorite jeans might once have been plastic bottles? This is the world of rPET, also known as recycled polyester (再生聚酯纤维). 16 As a result, a used water bottle can take on a new life as activewear or even high-fashion pieces. 17 First, plastic bottles are collected, sorted, and cleaned. After cleaning, they are cut, melted into liquid, and stretched into thin fibers. These fibers are then spun into yarn (纱线), which can be woven into different kinds of fabric. Finally, the fabric goes through finishing processes such as printing or coating to achieve the desired color, pattern, and performance. Some people assume that clothing made from “waste” must be cheap or low-quality. It is true that plastic-based fabrics can be less breathable and may feel rough for people with sensitive skin. 18 According to a Textile (纺织品) Exchange report, the use of rPET grew by 20% between 2020 and 2021, and made up about 14% of all global polyester production in 2022. This growth comes from rising awareness of both its practical advantages and its environmental value. In terms of performance, rPET is strong, durable, and quick-drying — qualities that make it ideal for sportswear. 19 Beyond performance, rPET supports the environment. Producing it uses 99% less water than producing traditional polyester, an important benefit for water-stressed regions involved in textile manufacturing. It also helps reduce waste. About 25 rPET bottles can be turned into the fibers for one jacket. 20 rPET is not a perfect solution to plastic pollution, but it is a meaningful step toward more sustainable fashion and a cleaner planet. A．It is also lightweight and wrinkle-resistant. B．However, market trends tell a different story. C．The transformation happens through several steps. D．This keeps millions of plastic bottles out of landfills each year. E．Recycling rPET fabric back into new fabric can be challenging. F．While it is safe to wear, it releases microplastics when it is washed. G．Unlike traditional polyester made from petrol, rPET uses existing plastic. 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。 I used to hate running.

It was May, yet we walked up a snow-covered hill. When we noticed our jeans were wet up to our knees, it did not dampen our spirits Not once did we say, “Let’s turn around.” This was our vacation, and we were on an adventure. Little did we know this was the beginning of many more surprises. The trail was marked as an easy one-kilometer like yet we were already walking a long distance. Our light-heartedness stopped when we came out into a clearing and saw a parking lot without our rental car in it. As my eyes scanned the surroundings, nothing looked familiar. My heart raced. I realized we were lost in a national park that did not officially open for another week. Usually, I am the calm one in the relationship, but my husband surprised me with his calmness. This did not comfort me; in fact, it heightened my fear. As we walked, I asked my husband to call for help, but there was no cell-phone signal in this isolated（偏僻的）area. It was awfully quiet except for our footsteps hitting the road, and my heavy breathing. My husband suggested we conserve energy and walk slower. With each step on the road, my feet and thighs hurt while my mind raced with thoughts about people who got lost in the Canadian woods for days. My vision sharpened. I noticed everything around me: the trees, rocks and snow. I thought we could eat the snow on the ground in case we needed water. For the first time in my life, I was ready and willing to get a ride, but we did not meet with a single car on the road. Silently, I prayed multiple times. We focused on each other, made joint decisions and connected through gratitude. We managed to stay on the main road and walked straight on. Paragraph 1: My husband suddenly spotted a small building on a hill in the distance. __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Paragraph 2: Just then, a friendly woman appeared, saying, “Hello.” __________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 原创精品资源学科网独家享有版权，侵权必究！1 1 / 12 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $第一节听下面5段对话。每段对话后有一个小题，从题中所给的ABC3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。现在你有5秒钟的时间阅读第一小题的有关内容。How much do you wait now?
