There are three very 11 paintings, and most people cannot tell which one is the artist’s original (原作). To art experts, there has been broad agreement that the paintings held by Russia’s Hermitage Museum and France’s Wildenstein Collection were created by the artist, 12 the one at Britain’s Badminton House is only a copy. But artificial intelligence (AI) disagreed. In September 2025, Swiss AI company Art Recognition said there’s an almost 86 percent chance that Badminton House’s painting is real, while Wildenstein’s one is 13 a copy. This event shows AI’s new role in deciding whether an artwork is real. In the past, human experts identified real artworks from copies using their 14 knowledge of artists and modern technologies such as infrared imaging (红外成像). Today, AI might serve as another helpful tool for experts. The technology can study small details from images of artworks. It then 15 these features with real works by the same artist to find differences that experts and other scientific methods might miss. However, many experts don’t fully trust AI to identify real art. They pointed out that AI can give results without explaining 16 it reached them. Also, the technology is only as good as the data it’s trained on, meaning both the number and quality of painting images can affect its accuracy (准确性). The Art Newspaper reported that proper AI training can require thousands of images, but few artists have produced that many works. Artists may also change their styles 17 , so AI that only looks for fixed patterns can easily make mistakes. As art is subjective, neither AI nor humans can be completely certain about their judgments. Currently, AI 18 only the likelihood of a painting being created by a particular artist, so it 19 be the only method used for authentication. Instead, it should be used together with human knowledge and scientific testing to reach the most reliable results. “I strongly believe that the future of art authentication 20 in the collaboration (协作) between AI and experts,” Art Recognition’s CEO Carina Popovici told ART news. 11．A．common B．different C．unique D．similar 12．A．and B．so C．while D．but 13．A．finally B．likely C．simply D．hardly 14．A．little B．deep C．strong D．powerful 15．A．matches B．compares C．changes D．improves 16．A．that B．what C．how D．whether 17．A．gradually B．suddenly C．instead D．immediately 18．A．invents B．creates C．imagines D．provides 19．A．can’t B．shouldn’t C．may not D．mustn’t 20．A．lies B．depends C．makes D．happens 三、阅读理解（共两节, 15小题; 每小题2分, 满分30分） 第一节: 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。 A ROBOTS ARE AMAZING MACHINES that can do difficult jobs on their own. Early robots were controlled by radio or wires, but modern robots have computer “brains” that tell them what to do. Robots now build things in factories, clean our homes and even explore outer space! 21．Which part of a robot is described to move the arms and legs? A．Chassis. B．Sensors. C．Actuators. D．Processor. 22．Which news headlines show the abilities of robots mentioned in the poster? ① China develops ‘electric spider’ robot for space missions ② Robots prepare coffee in Shenzhen ③ The future of home chores: Meet CC ④ Robots make cars at JAC×Huawei Superfactory ⑤ Robot performs 1st operation without human help ⑥ Robots welcome students back to school in Xishan District A．①②③⑤ B．①③④⑤ C．②③④⑤ D．③④⑤⑥ 23．Why do you think big and bold letters are used at the beginning of the poster? A．To have the poster look even more lively and humorous. B．To use a different writing style to draw readers’ attention. C．To stress the robots’ names and show the robots’ features. D．To make the meanings behind the words easy to understand. B The rise of “deepfake” technology has alarmed governments worldwide, but a lesser-known threat lurks in the form of “voice skinning”—using AI to clone a person’s voice from just a few seconds of audio. Cybercriminals have already exploited this to trick employees into transferring funds, claiming to be the CEO. In one 2024 case, a British energy firm lost $243,000 after a manager received a call from a deepfake of his German boss’s voice, complete with the subtle accent and phrasing. The fraud was detected only after the money was gone. Traditional voice authentication systems, which rely on comparing spectrograms, are increasingly vulnerable. In response, researchers are developing “liveness detection” for voices. The approach is similar to anti-spoofing in facial recognition: ask the speaker to perform a random action that a pre-recorded clip cannot. For example, the system might say, “Now say the number 5 while humming.” A real human can do this; a deepfake, which plays back a fixed sample, cannot. More advanced methods analyze the acoustic properties of the vocal tract—tiny, involuntary micro-fluctuations that occur when a person breathes or shifts posture. These “biometric signatures” are nearly impossible for AI to synthesize because they are chaotic and context-dependent. Nevertheless, attackers are adapting. Generative adversarial networks (GANs) can now simulate breathing patterns if fed enough training data. The arms race between forgery and detection continues. Legal frameworks are lagging; in most countries, using a deepfake voice for fraud is prosecuted under existing wire fraud laws, which do not fully address the unique challenges of synthetic media. For instance, how do you prove intent when the criminal claims the AI “accidentally” generated the voice? And what recourse does a victim have against an anonymous botnet? Some tech companies advocate for “watermarking” all AI-generated audio—embedding an inaudible digital signature that can be traced. Critics argue that watermarking can be stripped, and it places the burden on creators rather than on detection systems. Europe’s proposed AI Act includes a requirement for clear labeling of deepfakes, but enforcement is problematic. As Dr. Helen Zhou, a cybersecurity professor at MIT, warns: “We are training people to trust nothing they hear. That erosion of trust may be the deepest damage of all.” 24．What is “voice skinning” primarily used for in the context of the passage? A．Entertainment and dubbing for movies. B．Assisting people with speech disabilities. C．Committing financial fraud. D．Improving voice assistant accuracy. 25．How does “liveness detection” work for voices? A．It compares the voice to a database of celebrities. B．It asks the speaker to perform a random, unrepeatable action. C．It records the call for manual review later. D．It blocks all calls from unknown numbers. 26．What is a major legal challenge mentioned regarding deepfake voice fraud? A．There are no laws against cybercrime. B．Proving criminal intent is difficult. C．All deepfakes are protected as free speech. D．Banks refuse to cooperate with police. C Imagine you just finished a hard hike to the top of a mountain. The view of the city below is beautiful, and you want to take a photo. But it’s already quite dark, and you’re not sure you’ll get a good shot. Luckily, your phone has an AI night mode. It can take great photos even after sunset. Here’s something you may not know: that night mode may have been trained on computer-made nighttime images—scenes that were never actually photographed. This kind of data is called synthetic data. Why use synthetic data? AI researchers use up all the real data on the internet, so they turn to synthetic data. But this creates a problem. In science, making up data is a very bad thing. So how can computer-made data be good? Is it just a nice word for lying? As a researcher, I think it comes down to why you do it and how open you are about it. Synthetic data is usually not made to cheat. In fact, using it can be the right thing to do. For example, showing real people’s faces can violate privacy, but computer-made faces offer the same benefits without that risk. There are other reasons. Some things are so rare that there isn’t enough real data. Instead of letting this become a big problem, researchers create those situations with computers. Also, collecting real data can be costly or dangerous. Imagine collecting data for a self-driving car during a storm. It’s much easier and safer to create such data with computers. How is synthetic data made? Researchers create synthetic data in two main ways. One method uses physics-based models—for example, using the laws of light to show how a scene would look. The other method uses AI that learns from real data and then creates new, realistic text, images, and videos. Is synthetic data perfect? Synthetic data is not perfect. It is only as good as the model it comes from. Researchers have to be careful about biases—unfair patterns in the data. It is also important to know the difference between computer-made data and the real world. Synthetic data is great for training AI, but the final system should be tested with real data before it is used. AI systems learn by finding patterns, but they cannot tell what is real or true. The desire for truth belongs to people, not machines. So next time you use a cool AI feature, remember: synthetic data may have helped train it. But reality is still the final judge of what we create. 27．Why does the writer begin the passage with the example of taking a photo on a dark mountain top? A．To explain how AI night mode works in detail. B．To show that hiking is a popular outdoor activity. C．To lead into the topic of synthetic data used in AI training. D．To prove that phone cameras are better than professional ones. 28．What is synthetic data according to the passage? A．Information is stored in AI night modes. B．Data collected from real-life situations. C．Man-made data was used to train AI systems. D．Real photos taken by phones in dark places. 29．How does the writer mainly support his opinion about synthetic data? A．By arguing real data is bad. B．By showing its uses and limits. C．By listing AI models using it. D．By comparing it with real data. 30．Which of the following is the best title for the passage? A．Why AI Will Soon Replace Human Judgment B．The Privacy Problems of Using Real Face Data C．How AI Night Mode Helps You Take Photos in the Dark D．Synthetic Data Is Useful but Still Needs Real-World Checks 第二节: 阅读下面短文, 从短文后所给的选项中选出能填入短文空白处的最佳选项, 使短文通顺连贯, 其中有两项是多余选项。 Are your fruits and vegetables really clean enough to eat? Sirish Subash, a 14-year-old student from Snellville, Georgia, US, recently won the 3M Young Scientist Challenge. 31 This won him $ 25,000 and the title of “Best Young Scientist in America”. Subash’s idea for the tool came from a simple yet important question. His mother always told him to wash fruit before eating it. 32 He learned that 70 percent of fruits and vegetables have pesticides. They can bring possible health problems like cancer. Washing only gets rid of part of the pesticides. “If we could find them, we could avoid eating them and lower the risk of those health problems,” Subash said. 33 It works by shining lights and seeing how light reflects (反射) off food. With the help of a sensor (传感器), a screen and an AI learning model, the tool can find out if there are pesticides around. To use it, users must point PestiSCAND at the fruit or vegetable to see if they need to wash it again. 34 During testing, PestiSCAND was right more than 85 percent of the time in finding pesticides. Subash plans to improve his tool and hopes to get it to market by the time he starts college. 35 “In 15 years, I hope to be designing and building devices that can help make the world a better place,” said Subash. A．This led Subash to invent PestiSCAND, a small tool that people can carry around. B．They can check the results in an app on their phones. C．The percentage of fruits and vegetables with pesticides (农药). D．The boy wondered if the action did any good. E．His love for science will never go away. F．Subash will give up his love for science after college. G．He made a tool that can find pesticides on fruits and vegetables. 四、词汇运用（共10小题; 每小题1分, 满分10分） 第一节 根据句意，用括号中所给汉语提示或英语单词的适当形式填空。在横线上写出空缺处所填单词的正确形式。 36．The (递送) service by robots makes online‑shopping much faster. 37．When the smart machine breaks down, it will send out a (警示). 38．With the help of robotic systems, doctors in this hospital can complete operations (effective) than before. 39．Q-bot, the trusted robot helper, is very good at (pack) suitcases according to different weather and trip plans. 40．So far, hundreds of nanobots (develop) for medical research in the laboratory of Jiangsu Province. 第二节 阅读短文，从方框中选择适当的词并用其正确形式填空，使短文通顺完整，每个单词或短语仅用一次（其中一项为多余选项）。     abroad,  amazing,  artificial,  first,  more than,  understand Amy: Hi, Tom!

A group of high school students in southern China o 47 their answers, moving millions of people. Yu Yaxuan, a Chinese language teacher at Shenzhen Nanshan Foreign Language School (Group) in Guangdong province, recently collected 54 surveys from her students, each containing only one question: “If you had to choose one Chinese c 48 to prove you’re not AI, what would it be?” The answers surprised Yu and later impressed many people on the internet after a video about the exercise went viral, leading to heated discussion about the meaning of being human. Two students offered seemingly o 49 answers: “urgent” and “slow”. “Robots don’t understand why humans are always in a hurry,” one student wrote. “It takes 30 minutes for a hospital to give back test results, so why do patients check them every few minutes? Humans do not live in purely objective time. Our experience of time is s 50 by emotion.” Another student, surnamed Wu, didn’t agree. “When we think of speed and efficiency, we think of AI, yet humans long to slow down with those they care about,” Wu wrote. “AI is always pursuing speed and correct results, but I wish for humans to walk slowly, speak slowly and grow up slowly. I am willing to spend time on things that make life beautiful.” Other students chose words such as “doubt” and “finite”. “Will AI doubt its creator?” one student asked. Another wrote: “AI is infinite, but e 51 about me is finite—the knowledge I’ve g 52 , the people I’ve met, the stories I’ve heard, my life and my time. AI is valuable because it is infinite, while I am e 53 more precious because I am finite.” Other answers included “courage”, “faith”, “hate”, “r 54 ”, “love” and “hurt”. “What t 55 moves people may not be a single class, but the faint glimmers of humanity that digitalization can’t delete,” Yu said. 六、阅读表达（共 5 小题; 每小题 2分, 满分10分） 阅读短文，根据短文内容用英语回答问题，每题答案不超过6个词。 In recent years, AI technology has been used widely in our daily life. Is AI a useful tool for learning? Is it bad for students' ability to think? Here is what our students told us. Some students depend on AI too much. As a result, they don’t even know how to do the most simple things. However, I believe that AI can be a useful tool. My history teacher uses AI to help him plan lessons and make reading passages shorter. He also teaches us how to use AI in the right way. He shows us useful tips like turning notes into a study guide. That’s completely different from using it to write everything for us. In a word, it’s not the tool that’s the problem, but it’s how people use it. AI should help us students learn, not help us avoid learning. I believe that students who use AI for schoolwork are not learning. When they use AI, it just builds up an answer from the Internet and does not allow students to learn how to research a topic, understand articles, or learn by heart. Some students do not use their own minds when putting the results on their schoolwork. As a result, they have missed the chance to grow. What’s worse, AI may give some false information to students, and something terrible will happen. 56．Who thinks AI can be a useful tool for learning, Sally or Tom? 57．How does Sally’s teacher help them use AI better? 58．Why do some students miss the chance to grow, according to Tom? 59．What does Tom think AI may give students? 60．What do you think of using AI for learning? 七、书面表达（共1小题; 满分20分） 61．习近平总书记强调：“科技兴则民族兴，科技强则国家强。”假如你是李华，将参加学校“Technology Makes Life Better and Brighter”主题英语演讲比赛。请写一篇演讲稿，内容包括： 1.

Instead, it should be used together with human knowledge and scientific testing to reach the most reliable results. “I strongly believe that the future of art authentication 20 in the collaboration (协作) between AI and experts,” Art Recognition’s CEO Carina Popovici told ART news. 11．A．common B．different C．unique D．similar 12．A．and B．so C．while D．but 13．A．finally B．likely C．simply D．hardly 14．A．little B．deep C．strong D．powerful 15．A．matches B．compares C．changes D．improves 16．A．that B．what C．how D．whether 17．A．gradually B．suddenly C．instead D．immediately 18．A．invents B．creates C．imagines D．provides 19．A．can’t B．shouldn’t C．may not D．mustn’t 20．A．lies B．depends C．makes D．happens 【答案】 11．D 12．C 13．B 14．B 15．B 16．C 17．B 18．D 19．B 20．A 【导语】本文围绕卡拉瓦乔名画《鲁特琴演奏者》的真伪争议展开，介绍了AI技术在艺术品鉴定中的应用、优势与局限，指出未来鉴定需要AI与人类专家协作。 【详解】11．句意：有三幅非常相似的画作，大多数人无法分辨哪一幅是艺术家的原作。 后文提到“most people cannot tell which one is the artist’s original”，说明三幅画非常相似，similar表示“相似的”，符合语境。 12．句意：艺术专家普遍认为，俄罗斯冬宫博物馆和法国威尔登斯坦收藏的画作是艺术家所作，而英国巴德明顿府邸的那幅只是复制品。 空格前说专家认同两幅是真迹，空格后说另一幅只是复制品，前后是对比关系，while表示“然而”，专门用于对比两种不同情况，符合逻辑。 13．句意：2025年9月，瑞士AI公司Art Recognition表示，巴德明顿府邸的画作有近86%的概率是真迹，而威尔登斯坦的画作很可能是复制品。 AI明确说英国那幅有86%的概率是真迹，对应得出法国那幅很可能是复制品，likely表示“很可能”，符合AI给出概率结论的语境。 14．句意：过去，人类专家利用他们对艺术家的深厚了解和红外成像等现代技术来区分原作与复制品。 人类专家靠对艺术家的渊博知识辨别作品，deep knowledge是固定搭配，意为“渊博的知识”。 15．句意：然后它将这些特征与同一艺术家的真迹进行比较，找出专家和其他科学方法可能遗漏的差异。 compare...with...是固定搭配，意为“把……和……比较”，AI把待检测作品的特征和同一艺术家的真迹对比，找出人眼可能错过的差异。 16．句意：他们指出，AI可以给出结果，却无法解释它是如何得出这些结果的。 反对AI的专家指出，AI只会给出结果，不会解释如何得出这个结果，how表示“如何”，符合逻辑。 17．句意：艺术家也可能突然改变他们的风格，因此只寻找固定模式的AI很容易出错。 艺术家的创作风格也可能突然发生变化，AI只找固定模式就容易出错，suddenly表示“突然”，符合实际语境。 18．句意：目前，AI只提供一幅画由特定艺术家创作的可能性，所以它不应该成为鉴定的唯一方法。 AI的作用是给出可能性结果，provide表示“提供”，符合语境。 19．句意：目前，AI只提供一幅画由特定艺术家创作的可能性，所以它不应该成为鉴定的唯一方法。 后文明确说AI需要和人类知识、科学检测结合使用，因此它不应该成为唯一的鉴定方法，shouldn’t表示“不应该”，符合建议的语气。 20．句意：“我坚信，艺术品鉴定的未来在于AI与专家之间的协作，”Art Recognition的首席执行官卡琳娜·波波维奇告诉ART新闻。 lie in是固定搭配，意为“在于”，符合搭配和句意。depend需要与介词on搭配，因此排除B项。 三、阅读理解（共两节, 15小题; 每小题2分, 满分30分） 第一节: 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。 A ROBOTS ARE AMAZING MACHINES that can do difficult jobs on their own. Early robots were controlled by radio or wires, but modern robots have computer “brains” that tell them what to do. Robots now build things in factories, clean our homes and even explore outer space! 21．Which part of a robot is described to move the arms and legs? A．Chassis. B．Sensors. C．Actuators. D．Processor. 22．Which news headlines show the abilities of robots mentioned in the poster? ① China develops ‘electric spider’ robot for space missions ② Robots prepare coffee in Shenzhen ③ The future of home chores: Meet CC ④ Robots make cars at JAC×Huawei Superfactory ⑤ Robot performs 1st operation without human help ⑥ Robots welcome students back to school in Xishan District A．①②③⑤ B．①③④⑤ C．②③④⑤ D．③④⑤⑥ 23．Why do you think big and bold letters are used at the beginning of the poster? A．To have the poster look even more lively and humorous. B．To use a different writing style to draw readers’ attention. C．To stress the robots’ names and show the robots’ features. D．To make the meanings behind the words easy to understand. 【答案】21．C 22．B 23．B 【导语】本文主要介绍了机器人的用途、构造以及微型纳米机器人的研发前景。 【详解】21．根据文中左侧图片中内容“ACTUATORS: motors that move different parts of the robot, like the arms and legs”可知，执行器（Actuators）负责驱动机器人四肢活动。 22．根据文章第一段“Robots now build things in factories, clean our homes and even explore outer space!”和右侧图片中“Nanobots are small robots that could be used to make things out of molecules (分子) or be injected (注射) into our bodies to deal with medical problems.”可知，文章中提到机器人用途有：工厂造物、居家清洁、探索太空、纳米机器人可用于医疗。故①太空探索、③家务清洁、④工厂造车、⑤医疗手术，四项符合原文；②做咖啡、⑥校园迎宾文中无对应描述。故选①③④⑤，对应选项B。 23．段落开头采用大写加粗标题“ROBOTS ARE AMAZING MACHINES”，目的是用醒目的排版样式，吸引读者阅读海报内容。 B The rise of “deepfake” technology has alarmed governments worldwide, but a lesser-known threat lurks in the form of “voice skinning”—using AI to clone a person’s voice from just a few seconds of audio. Cybercriminals have already exploited this to trick employees into transferring funds, claiming to be the CEO. In one 2024 case, a British energy firm lost $243,000 after a manager received a call from a deepfake of his German boss’s voice, complete with the subtle accent and phrasing. The fraud was detected only after the money was gone. Traditional voice authentication systems, which rely on comparing spectrograms, are increasingly vulnerable. In response, researchers are developing “liveness detection” for voices. The approach is similar to anti-spoofing in facial recognition: ask the speaker to perform a random action that a pre-recorded clip cannot. For example, the system might say, “Now say the number 5 while humming.” A real human can do this; a deepfake, which plays back a fixed sample, cannot. More advanced methods analyze the acoustic properties of the vocal tract—tiny, involuntary micro-fluctuations that occur when a person breathes or shifts posture. These “biometric signatures” are nearly impossible for AI to synthesize because they are chaotic and context-dependent. Nevertheless, attackers are adapting. Generative adversarial networks (GANs) can now simulate breathing patterns if fed enough training data. The arms race between forgery and detection continues. Legal frameworks are lagging; in most countries, using a deepfake voice for fraud is prosecuted under existing wire fraud laws, which do not fully address the unique challenges of synthetic media. For instance, how do you prove intent when the criminal claims the AI “accidentally” generated the voice? And what recourse does a victim have against an anonymous botnet? Some tech companies advocate for “watermarking” all AI-generated audio—embedding an inaudible digital signature that can be traced. Critics argue that watermarking can be stripped, and it places the burden on creators rather than on detection systems. Europe’s proposed AI Act includes a requirement for clear labeling of deepfakes, but enforcement is problematic. As Dr. Helen Zhou, a cybersecurity professor at MIT, warns: “We are training people to trust nothing they hear. That erosion of trust may be the deepest damage of all.” 24．What is “voice skinning” primarily used for in the context of the passage? A．Entertainment and dubbing for movies. B．Assisting people with speech disabilities. C．Committing financial fraud. D．Improving voice assistant accuracy. 25．How does “liveness detection” work for voices? A．It compares the voice to a database of celebrities. B．It asks the speaker to perform a random, unrepeatable action. C．It records the call for manual review later. D．It blocks all calls from unknown numbers. 26．What is a major legal challenge mentioned regarding deepfake voice fraud? A．There are no laws against cybercrime. B．Proving criminal intent is difficult. C．All deepfakes are protected as free speech. D．Banks refuse to cooperate with police. 【答案】24．C 25．B 26．B 【导语】本文是一篇说明文。主要介绍了“声音克隆”（voice skinning）技术被用于金融诈骗的现状，研究人员开发的“活体检测”应对方案，以及当前法律框架下面临的证明意图难等挑战。 【详解】24．根据第一段中的“Cybercriminals have already exploited this to trick employees into transferring funds, claiming to be the CEO. In one 2024 case, a British energy firm lost $243,000...”可知，在本文语境下，“声音克隆”主要被用于实施金融诈骗。 25．根据第二段中的“The approach is similar to anti-spoofing in facial recognition: ask the speaker to perform a random action that a pre-recorded clip cannot.”可知，声音“活体检测”的工作原理是要求说话者执行随机且不可重复的动作。 26．根据第三段中的“Legal frameworks are lagging... For instance, how do you prove intent when the criminal claims the AI “accidentally” generated the voice?”可知，文中提到的主要法律挑战是难以证明犯罪意图。 C Imagine you just finished a hard hike to the top of a mountain. The view of the city below is beautiful, and you want to take a photo. But it’s already quite dark, and you’re not sure you’ll get a good shot. Luckily, your phone has an AI night mode. It can take great photos even after sunset. Here’s something you may not know: that night mode may have been trained on computer-made nighttime images—scenes that were never actually photographed. This kind of data is called synthetic data. Why use synthetic data? AI researchers use up all the real data on the internet, so they turn to synthetic data. But this creates a problem. In science, making up data is a very bad thing. So how can computer-made data be good? Is it just a nice word for lying? As a researcher, I think it comes down to why you do it and how open you are about it. Synthetic data is usually not made to cheat. In fact, using it can be the right thing to do. For example, showing real people’s faces can violate privacy, but computer-made faces offer the same benefits without that risk. There are other reasons. Some things are so rare that there isn’t enough real data. Instead of letting this become a big problem, researchers create those situations with computers. Also, collecting real data can be costly or dangerous. Imagine collecting data for a self-driving car during a storm. It’s much easier and safer to create such data with computers. How is synthetic data made? Researchers create synthetic data in two main ways. One method uses physics-based models—for example, using the laws of light to show how a scene would look. The other method uses AI that learns from real data and then creates new, realistic text, images, and videos. Is synthetic data perfect? Synthetic data is not perfect. It is only as good as the model it comes from. Researchers have to be careful about biases—unfair patterns in the data. It is also important to know the difference between computer-made data and the real world. Synthetic data is great for training AI, but the final system should be tested with real data before it is used. AI systems learn by finding patterns, but they cannot tell what is real or true. The desire for truth belongs to people, not machines. So next time you use a cool AI feature, remember: synthetic data may have helped train it. But reality is still the final judge of what we create. 27．Why does the writer begin the passage with the example of taking a photo on a dark mountain top? A．To explain how AI night mode works in detail. B．To show that hiking is a popular outdoor activity. C．To lead into the topic of synthetic data used in AI training. D．To prove that phone cameras are better than professional ones. 28．What is synthetic data according to the passage? A．Information is stored in AI night modes. B．Data collected from real-life situations. C．Man-made data was used to train AI systems. D．Real photos taken by phones in dark places. 29．How does the writer mainly support his opinion about synthetic data? A．By arguing real data is bad. B．By showing its uses and limits. C．By listing AI models using it. D．By comparing it with real data. 30．Which of the following is the best title for the passage? A．Why AI Will Soon Replace Human Judgment B．The Privacy Problems of Using Real Face Data C．How AI Night Mode Helps You Take Photos in the Dark D．Synthetic Data Is Useful but Still Needs Real-World Checks 【答案】27．C 28．C 29．B 30．D 【导语】本文主要介绍了什么是“合成数据”，为什么要使用它，以及它目前存在的局限性，旨在让读者客观认识这一人工智能领域的关键训练技术。 【详解】27．第一段描述了在黑暗山顶拍照的场景，第二段紧接着指出：“This kind of data is called synthetic data.”。作者利用生活中常见的手机AI夜间拍照功能作为切入点，是为了引出下文关于“合成数据”及其在AI训练中应用的话题。 28．第二段对该术语进行了定义：“…computer-made nighttime images—scenes that were never actually photographed. This kind of data is called synthetic data.”。这明确说明合成数据是由计算机生成的、用于训练AI系统的非真实拍摄数据。 29．文章在“Why use synthetic data?”部分介绍了其在隐私保护、稀有数据模拟和安全性方面的优势，在“Is synthetic data perfect?”部分则指出了其偏见和局限性。通过展示其用途和局限，作者全面地支持了自己对合成数据的观点。 30．文章大部分篇幅在讨论合成数据的必要性，但第七段强调：“Synthetic data is not perfect…the final system should be tested with real data before it is used.”。选项D“合成数据很有用但仍需现实检验”精准且高度概括了文章既肯定价值又指出不足的中心思想。 第二节: 阅读下面短文, 从短文后所给的选项中选出能填入短文空白处的最佳选项, 使短文通顺连贯, 其中有两项是多余选项。 Are your fruits and vegetables really clean enough to eat? Sirish Subash, a 14-year-old student from Snellville, Georgia, US, recently won the 3M Young Scientist Challenge. 31 This won him $ 25,000 and the title of “Best Young Scientist in America”. Subash’s idea for the tool came from a simple yet important question. His mother always told him to wash fruit before eating it. 32 He learned that 70 percent of fruits and vegetables have pesticides. They can bring possible health problems like cancer. Washing only gets rid of part of the pesticides. “If we could find them, we could avoid eating them and lower the risk of those health problems,” Subash said. 33 It works by shining lights and seeing how light reflects (反射) off food. With the help of a sensor (传感器), a screen and an AI learning model, the tool can find out if there are pesticides around. To use it, users must point PestiSCAND at the fruit or vegetable to see if they need to wash it again. 34 During testing, PestiSCAND was right more than 85 percent of the time in finding pesticides. Subash plans to improve his tool and hopes to get it to market by the time he starts college. 35 “In 15 years, I hope to be designing and building devices that can help make the world a better place,” said Subash. A．This led Subash to invent PestiSCAND, a small tool that people can carry around. B．They can check the results in an app on their phones. C．The percentage of fruits and vegetables with pesticides (农药). D．The boy wondered if the action did any good. E．His love for science will never go away. F．Subash will give up his love for science after college. G．He made a tool that can find pesticides on fruits and vegetables. 【答案】31．G 32．D 33．A 34．B 35．E 【导语】本文是一篇说明文，讲述了美国14岁学生Sirish Subash发明了可检测果蔬农药残留的工具，并因此赢得了3M青年科学家挑战赛的故事。 【详解】31．空前提到Sirish Subash赢得了3M青年科学家挑战赛，空后说了获得的奖金和头衔。此处需要补充他获奖的具体成果。选项G“He made a tool that can find pesticides on fruits and vegetables.”概括了他的发明成就，与上下文逻辑连贯。 32．空前说母亲告诉他吃水果前要清洗，空后说他了解到70%的果蔬有农药。此处需要一个过渡句，选项D“The boy wondered if the action did any good.”承接了母亲的建议，并引出后文他去了解农药相关知识的行为。 33．空前是Subash的引言，提到如果能发现农药就能避免食用并降低健康风险，空后介绍“它”如何工作，这里的“它”指代某个工具。选项A“This led Subash to invent PestiSCAND, a small tool that people can carry around.”正式引出了工具的名称，与后文的“It”指代一致。 34．本段介绍如何使用该工具。空前说用户必须将工具指向果蔬，空后提到测试准确率。此处应补充使用过程的下一步。选项B“They can check the results in an app on their phones.”描述了用户操作后的反馈环节，符合使用流程。 35．空前提到他计划在大学前将工具推向市场，空后引用他15年后的愿望。此处需要表达他对科学持续的热情。选项E“His love for science will never go away.”与上下文关于未来规划和对科学追求的语境相符。 四、词汇运用（共10小题; 每小题1分, 满分10分） 第一节 根据句意，用括号中所给汉语提示或英语单词的适当形式填空。在横线上写出空缺处所填单词的正确形式。 36．The (递送) service by robots makes online‑shopping much faster. 【答案】delivery 【详解】句意：机器人递送服务让网购速度快很多。delivery 名词，意为 “递送”，在句子中作主语，故填 delivery。 37．When the smart machine breaks down, it will send out a (警示). 【答案】warning 【详解】句意：当智能机器发生故障时，它会发出警示。warning 可数名词，意为 “警示，警告”；不定冠词 a 后面接单数形式，故填 warning。 38．With the help of robotic systems, doctors in this hospital can complete operations (effective) than before. 【答案】more effectively 【详解】句意：在机器人系统的帮助下，这家医院的医生做手术比以前更高效。修饰动词 complete 需要用副词；句中 than 表示比较，因此用副词 effectively 的比较级 more effectively。 39．Q-bot, the trusted robot helper, is very good at (pack) suitcases according to different weather and trip plans. 【答案】packing 【详解】句意：可靠的机器人助手 Q-bot 很擅长根据不同的天气和行程计划收拾行李箱。固定搭配 be good at doing sth. 中，at 是介词，后接动名词形式，pack 的动名词为 packing。 40．So far, hundreds of nanobots (develop) for medical research in the laboratory of Jiangsu Province. 【答案】have been developed 【详解】句意：到目前为止，江苏省的实验室已经研发出数百个用于医学研究的纳米机器人。so far 是现在完成时的标志词；主语 nanobots 与动词 develop 是被动关系，因此用现在完成时的被动语态 have been developed。 第二节 阅读短文，从方框中选择适当的词并用其正确形式填空，使短文通顺完整，每个单词或短语仅用一次（其中一项为多余选项）。     abroad,  amazing,  artificial,  first,  more than,  understand Amy: Hi, Tom! Did you watch the documentary about 41 intelligence on Channel 9 last night? Tom: You mean “The AI Revolution”? Yes, I did. It was 42 just educational—it was mind-blowing! Did you know that AI can now compose music that sounds like Beethoven? Amy: Really? I don’t fully 43 how that works, but I find it fascinating. Imagine an AI writing a symphony! Tom: It was my 44 time seeing an AI-generated piece performed by a real orchestra. The audience couldn’t tell the difference. Amy: In fact, AI is being used in creative fields all over the world, both at home and 45 . Some artists worry about losing their jobs, but others say AI is just another tool, like the camera or the paintbrush. Tom: I agree. It’s not about replacing humans — it’s about expanding what we can create. 【答案】41．artificial 42．more than 43．understand 44．first 45．abroad 【导语】这段对话主要围绕人工智能纪录片展开，二人谈论AI作曲等应用，探讨AI在全球创意领域的使用与对艺术行业的影响。 【详解】41．句意：你昨晚看了九频道有关人工智能的纪录片吗？根据下文Tom提到的“The AI Revolution”可知，此处指关于“人工智能”的纪录片，“artificial intelligence”为固定短语，意为“人工智能”。 42．句意：它不仅仅有教育意义，还令人惊叹。根据后半句“it was mind-blowing”可知，纪录片的效果超出了教育意义，“more than just...”意为“不仅仅是……”，符合语境。 43．句意：我不完全明白它的原理，但觉得很有意思。空格前有助动词don’t和副词fully，此处需填动词原形；根据句意，指不完全“理解”其原理，故填understand。 44．句意：这是我第一次欣赏由真实管弦乐队演奏AI创作的乐曲。“It was my first time doing sth.”是常用句型，意为“这是我第一次做某事”，符合语境。 45．句意：人工智能在国内外创意领域均投入使用。“at home and abroad”是固定搭配，意为“国内外”，与前面的“all over the world”相呼应。 五、短文填空（共10小题; 每小题1分, 满分10分） 根据短文内容及所给首字母提示写出所缺单词，使短文意思完整，每空一词。 When artificial intelligence (AI) makes life easier than ever before, what is the true v 46 of human being? A group of high school students in southern China o 47 their answers, moving millions of people. Yu Yaxuan, a Chinese language teacher at Shenzhen Nanshan Foreign Language School (Group) in Guangdong province, recently collected 54 surveys from her students, each containing only one question: “If you had to choose one Chinese c 48 to prove you’re not AI, what would it be?” The answers surprised Yu and later impressed many people on the internet after a video about the exercise went viral, leading to heated discussion about the meaning of being human. Two students offered seemingly o 49 answers: “urgent” and “slow”. “Robots don’t understand why humans are always in a hurry,” one student wrote. “It takes 30 minutes for a hospital to give back test results, so why do patients check them every few minutes? Humans do not live in purely objective time. Our experience of time is s 50 by emotion.” Another student, surnamed Wu, didn’t agree. “When we think of speed and efficiency, we think of AI, yet humans long to slow down with those they care about,” Wu wrote. “AI is always pursuing speed and correct results, but I wish for humans to walk slowly, speak slowly and grow up slowly. I am willing to spend time on things that make life beautiful.” Other students chose words such as “doubt” and “finite”. “Will AI doubt its creator?” one student asked. Another wrote: “AI is infinite, but e 51 about me is finite—the knowledge I’ve g 52 , the people I’ve met, the stories I’ve heard, my life and my time. AI is valuable because it is infinite, while I am e 53 more precious because I am finite.” Other answers included “courage”, “faith”, “hate”, “r 54 ”, “love” and “hurt”. “What t 55 moves people may not be a single class, but the faint glimmers of humanity that digitalization can’t delete,” Yu said. 【答案】 46．value/alue 47．offered/ffered 48．character/haracter 49．opposite/pposite 50．shaped/haped 51．everything/verything 52．gained/ained 53．even/ven 54．regret/egret 55．truly/ruly 【导语】本文是一篇记叙文，文章通过学生们对“用什么证明自己不是AI”的回答，探讨了人类区别于AI的独特价值，如情感、有限性与人性光辉。 【详解】46．句意：当人工智能(AI)让生活变得比以往任何时候都更容易的时候，人类的真正价值是什么？文章开篇提出一个核心问题：“what is the true…of human being?”，结合下文和首字母提示，学生们寻找的是人类独有的品质，也就是人类的“价值”。首字母v对应value。 47．句意：中国南方的一群高中生给出了他们的答案，感动了数百万人。分析句子，该句缺谓语。语境提示，该句陈述过去发生的动作，所以时态为一般过去时。空格前“A group of high school students”和空格后“their answers”，结合首字母提示，此处指高中生给出了他们的答案。首字母o对应offered。 48．句意：余雅萱是广东深圳南山外国语学校(集团)的一名语文老师，她最近收集了54份来自学生的调查问卷，每份问卷都只有一个问题:“如果你必须选择一个汉字来证明你不是人工智能，你会选择什么？”Chinese character“汉字”。 49．句意：两个学生给出了看似相反的答案:“急”和“慢”。“urgent”和“slow”是两个含义完全相反的词。因此，这两个答案看起来是相反的。首字母o对应opposite。 50．句意：我们对时间的体验是由情感塑造的。上文“Humans do not live in purely objective time.”提到人类不生活在纯粹的客观时间里。这句话解释原因。首字母s对应shaped，shaped意为“塑造；影响”，符合逻辑。 51．句意：AI是无限的，但我的一切都是有限的——我获得的知识，我遇到的人，我听到的故事，我的生活和我的时间。下文列举了“我学到的知识、遇到的人、听到的故事、我的生命和时间”，这些都是概括性的。everything about me“关于我的一切”，统领下文。 52．句意：AI是无限的，但我的一切都是有限的——我获得的知识，我遇到的人，我听到的故事，我的生活和我的时间。前文“the knowledge I’ve…”，结合首字母提示，该句时态为现在完成时，指我获得的知识。首字母g对应gained。 53．句意：人工智能因为它是无限的而有价值，而我因为我是有限的而更加珍贵。这句话是与前文AI的对比：AI因为它是无限的而有价值，而我因为我是有限的而……更珍贵。首字母e对应even，even用来修饰比较级more precious，加强语气，意为“甚至；更加”符合逻辑。 54．句意：其他答案包括“勇气”、“信念”、“仇恨”、“后悔”、“爱”和“伤害”。上下文中“courage”，“faith”，“hate”，“love”和“hurt”一系列词都是描述人类情感或状态的抽象名词。空格处应填一个同样属于情感范畴的词。首字母r对应regret。 55．句意：“真正打动人的可能不是某一个阶层，而是数字化无法抹去的人性的微弱闪光，”余雅萱说。分析句子“What…moves people may not be a single class”，该句不缺主要成分，空格处需要修饰动词moves。首字母对应truly，truly副词，意为“真正地”，符合语境。 六、阅读表达（共 5 小题; 每小题 2分, 满分10分） 阅读短文，根据短文内容用英语回答问题，每题答案不超过6个词。 In recent years, AI technology has been used widely in our daily life. Is AI a useful tool for learning? Is it bad for students' ability to think? Here is what our students told us. Some students depend on AI too much. As a result, they don’t even know how to do the most simple things. However, I believe that AI can be a useful tool. My history teacher uses AI to help him plan lessons and make reading passages shorter. He also teaches us how to use AI in the right way. He shows us useful tips like turning notes into a study guide. That’s completely different from using it to write everything for us. In a word, it’s not the tool that’s the problem, but it’s how people use it. AI should help us students learn, not help us avoid learning. I believe that students who use AI for schoolwork are not learning. When they use AI, it just builds up an answer from the Internet and does not allow students to learn how to research a topic, understand articles, or learn by heart. Some students do not use their own minds when putting the results on their schoolwork. As a result, they have missed the chance to grow. What’s worse, AI may give some false information to students, and something terrible will happen. 56．Who thinks AI can be a useful tool for learning, Sally or Tom? 57．How does Sally’s teacher help them use AI better? 58．Why do some students miss the chance to grow, according to Tom? 59．What does Tom think AI may give students? 60．What do you think of using AI for learning? 【答案】56．Sally. 57．By showing them useful tips. 58．Because they don’t use their minds. 59．False information. 60．Useful but risky./Helpful but terrible./A double-edged sword./... (答对一方面即可) 【导语】本文主要呈现了Sally与Tom两位学生对AI在学习中应用的不同观点，探讨了AI作为学习工具的利弊。 【详解】56．Sally的发言中提到“I believe that AI can be a useful tool”，而Tom反对用AI完成作业，因此答案为原文直接信息提取。 57．Sally提到老师“He shows us useful tips like turning notes into a study guide”，这是老师帮助学生正确使用AI的方式，可直接提取作答。 58．Tom提到“Some students do not use their own minds when putting the results on their schoolwork. As a result, they have missed the chance to grow”，Tom认为学生使用AI完成作业时，不会动用自己的思考，因此错失了成长的机会，直接点明了原因。 59．Tom在发言末尾指出“AI may give some false information to students”，Tom明确提出AI可能会给学生提供错误信息，直接提取关键信息即可。 60．本题为开放性问题，需结合文中两种观点作答，言之有理且不超过6个词即可。   七、书面表达（共1小题; 满分20分） 61．习近平总书记强调：“科技兴则民族兴，科技强则国家强。”假如你是李华，将参加学校“Technology Makes Life Better and Brighter”主题英语演讲比赛。请写一篇演讲稿，内容包括： 1. Why is technology important? 2. How does technology make your daily life better? (Give one or two examples such as AI, robots, and smartphones.) 3. What do you think of technology in future life? 注意： 1．短文中应包含所要求的信息。 2．词数90词左右，开头和结尾已经写好，不计入总词数。 3．短文中请勿提及真实校名及姓名。 Dear all, It’s my great honor to give a speech here. _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Thank you for listening. 【答案】例文 Dear all, It’s my great honor to give a speech here. As President Xi said, “Technology is vital for national prosperity.” It drives progress and solves problems, making our lives easier and more colorful.

There are three very 11 paintings, and most people cannot tell which one is the artist’s original (原作). To art experts, there has been broad agreement that the paintings held by Russia’s Hermitage Museum and France’s Wildenstein Collection were created by the artist, 12 the one at Britain’s Badminton House is only a copy. But artificial intelligence (AI) disagreed. In September 2025, Swiss AI company Art Recognition said there’s an almost 86 percent chance that Badminton House’s painting is real, while Wildenstein’s one is 13 a copy. This event shows AI’s new role in deciding whether an artwork is real. In the past, human experts identified real artworks from copies using their 14 knowledge of artists and modern technologies such as infrared imaging (红外成像). Today, AI might serve as another helpful tool for experts. The technology can study small details from images of artworks. It then 15 these features with real works by the same artist to find differences that experts and other scientific methods might miss. However, many experts don’t fully trust AI to identify real art. They pointed out that AI can give results without explaining 16 it reached them. Also, the technology is only as good as the data it’s trained on, meaning both the number and quality of painting images can affect its accuracy (准确性). The Art Newspaper reported that proper AI training can require thousands of images, but few artists have produced that many works. Artists may also change their styles 17 , so AI that only looks for fixed patterns can easily make mistakes. As art is subjective, neither AI nor humans can be completely certain about their judgments. Currently, AI 18 only the likelihood of a painting being created by a particular artist, so it 19 be the only method used for authentication. Instead, it should be used together with human knowledge and scientific testing to reach the most reliable results. “I strongly believe that the future of art authentication 20 in the collaboration (协作) between AI and experts,” Art Recognition’s CEO Carina Popovici told ART news. 11．A．common B．different C．unique D．similar 12．A．and B．so C．while D．but 13．A．finally B．likely C．simply D．hardly 14．A．little B．deep C．strong D．powerful 15．A．matches B．compares C．changes D．improves 16．A．that B．what C．how D．whether 17．A．gradually B．suddenly C．instead D．immediately 18．A．invents B．creates C．imagines D．provides 19．A．can’t B．shouldn’t C．may not D．mustn’t 20．A．lies B．depends C．makes D．happens 三、阅读理解（共两节, 15小题; 每小题2分, 满分30分） 第一节: 阅读下面短文, 从每题所给的A、B、C、D四个选项中, 选出最佳选项。 A ROBOTS ARE AMAZING MACHINES that can do difficult jobs on their own. Early robots were controlled by radio or wires, but modern robots have computer “brains” that tell them what to do. Robots now build things in factories, clean our homes and even explore outer space! 21．Which part of a robot is described to move the arms and legs? A．Chassis. B．Sensors. C．Actuators. D．Processor. 22．Which news headlines show the abilities of robots mentioned in the poster? ① China develops ‘electric spider’ robot for space missions ② Robots prepare coffee in Shenzhen ③ The future of home chores: Meet CC ④ Robots make cars at JAC×Huawei Superfactory ⑤ Robot performs 1st operation without human help ⑥ Robots welcome students back to school in Xishan District A．①②③⑤ B．①③④⑤ C．②③④⑤ D．③④⑤⑥ 23．Why do you think big and bold letters are used at the beginning of the poster? A．To have the poster look even more lively and humorous. B．To use a different writing style to draw readers’ attention. C．To stress the robots’ names and show the robots’ features. D．To make the meanings behind the words easy to understand. B The rise of “deepfake” technology has alarmed governments worldwide, but a lesser-known threat lurks in the form of “voice skinning”—using AI to clone a person’s voice from just a few seconds of audio. Cybercriminals have already exploited this to trick employees into transferring funds, claiming to be the CEO. In one 2024 case, a British energy firm lost $243,000 after a manager received a call from a deepfake of his German boss’s voice, complete with the subtle accent and phrasing. The fraud was detected only after the money was gone. Traditional voice authentication systems, which rely on comparing spectrograms, are increasingly vulnerable. In response, researchers are developing “liveness detection” for voices. The approach is similar to anti-spoofing in facial recognition: ask the speaker to perform a random action that a pre-recorded clip cannot. For example, the system might say, “Now say the number 5 while humming.” A real human can do this; a deepfake, which plays back a fixed sample, cannot. More advanced methods analyze the acoustic properties of the vocal tract—tiny, involuntary micro-fluctuations that occur when a person breathes or shifts posture. These “biometric signatures” are nearly impossible for AI to synthesize because they are chaotic and context-dependent. Nevertheless, attackers are adapting. Generative adversarial networks (GANs) can now simulate breathing patterns if fed enough training data. The arms race between forgery and detection continues. Legal frameworks are lagging; in most countries, using a deepfake voice for fraud is prosecuted under existing wire fraud laws, which do not fully address the unique challenges of synthetic media. For instance, how do you prove intent when the criminal claims the AI “accidentally” generated the voice? And what recourse does a victim have against an anonymous botnet? Some tech companies advocate for “watermarking” all AI-generated audio—embedding an inaudible digital signature that can be traced. Critics argue that watermarking can be stripped, and it places the burden on creators rather than on detection systems. Europe’s proposed AI Act includes a requirement for clear labeling of deepfakes, but enforcement is problematic. As Dr. Helen Zhou, a cybersecurity professor at MIT, warns: “We are training people to trust nothing they hear. That erosion of trust may be the deepest damage of all.” 24．What is “voice skinning” primarily used for in the context of the passage? A．Entertainment and dubbing for movies. B．Assisting people with speech disabilities. C．Committing financial fraud. D．Improving voice assistant accuracy. 25．How does “liveness detection” work for voices? A．It compares the voice to a database of celebrities. B．It asks the speaker to perform a random, unrepeatable action. C．It records the call for manual review later. D．It blocks all calls from unknown numbers. 26．What is a major legal challenge mentioned regarding deepfake voice fraud? A．There are no laws against cybercrime. B．Proving criminal intent is difficult. C．All deepfakes are protected as free speech. D．Banks refuse to cooperate with police. C Imagine you just finished a hard hike to the top of a mountain. The view of the city below is beautiful, and you want to take a photo. But it’s already quite dark, and you’re not sure you’ll get a good shot. Luckily, your phone has an AI night mode. It can take great photos even after sunset. Here’s something you may not know: that night mode may have been trained on computer-made nighttime images—scenes that were never actually photographed. This kind of data is called synthetic data. Why use synthetic data? AI researchers use up all the real data on the internet, so they turn to synthetic data. But this creates a problem. In science, making up data is a very bad thing. So how can computer-made data be good? Is it just a nice word for lying? As a researcher, I think it comes down to why you do it and how open you are about it. Synthetic data is usually not made to cheat. In fact, using it can be the right thing to do. For example, showing real people’s faces can violate privacy, but computer-made faces offer the same benefits without that risk. There are other reasons. Some things are so rare that there isn’t enough real data. Instead of letting this become a big problem, researchers create those situations with computers. Also, collecting real data can be costly or dangerous. Imagine collecting data for a self-driving car during a storm. It’s much easier and safer to create such data with computers. How is synthetic data made? Researchers create synthetic data in two main ways. One method uses physics-based models—for example, using the laws of light to show how a scene would look. The other method uses AI that learns from real data and then creates new, realistic text, images, and videos. Is synthetic data perfect? Synthetic data is not perfect. It is only as good as the model it comes from. Researchers have to be careful about biases—unfair patterns in the data. It is also important to know the difference between computer-made data and the real world. Synthetic data is great for training AI, but the final system should be tested with real data before it is used. AI systems learn by finding patterns, but they cannot tell what is real or true. The desire for truth belongs to people, not machines. So next time you use a cool AI feature, remember: synthetic data may have helped train it. But reality is still the final judge of what we create. 27．Why does the writer begin the passage with the example of taking a photo on a dark mountain top? A．To explain how AI night mode works in detail. B．To show that hiking is a popular outdoor activity. C．To lead into the topic of synthetic data used in AI training. D．To prove that phone cameras are better than professional ones. 28．What is synthetic data according to the passage? A．Information is stored in AI night modes. B．Data collected from real-life situations. C．Man-made data was used to train AI systems. D．Real photos taken by phones in dark places. 29．How does the writer mainly support his opinion about synthetic data? A．By arguing real data is bad. B．By showing its uses and limits. C．By listing AI models using it. D．By comparing it with real data. 30．Which of the following is the best title for the passage? A．Why AI Will Soon Replace Human Judgment B．The Privacy Problems of Using Real Face Data C．How AI Night Mode Helps You Take Photos in the Dark D．Synthetic Data Is Useful but Still Needs Real-World Checks 第二节: 阅读下面短文, 从短文后所给的选项中选出能填入短文空白处的最佳选项, 使短文通顺连贯, 其中有两项是多余选项。 Are your fruits and vegetables really clean enough to eat? Sirish Subash, a 14-year-old student from Snellville, Georgia, US, recently won the 3M Young Scientist Challenge. 31 This won him $ 25,000 and the title of “Best Young Scientist in America”. Subash’s idea for the tool came from a simple yet important question. His mother always told him to wash fruit before eating it. 32 He learned that 70 percent of fruits and vegetables have pesticides. They can bring possible health problems like cancer. Washing only gets rid of part of the pesticides. “If we could find them, we could avoid eating them and lower the risk of those health problems,” Subash said. 33 It works by shining lights and seeing how light reflects (反射) off food. With the help of a sensor (传感器), a screen and an AI learning model, the tool can find out if there are pesticides around. To use it, users must point PestiSCAND at the fruit or vegetable to see if they need to wash it again. 34 During testing, PestiSCAND was right more than 85 percent of the time in finding pesticides. Subash plans to improve his tool and hopes to get it to market by the time he starts college. 35 “In 15 years, I hope to be designing and building devices that can help make the world a better place,” said Subash. A．This led Subash to invent PestiSCAND, a small tool that people can carry around. B．They can check the results in an app on their phones. C．The percentage of fruits and vegetables with pesticides (农药). D．The boy wondered if the action did any good. E．His love for science will never go away. F．Subash will give up his love for science after college. G．He made a tool that can find pesticides on fruits and vegetables. 四、词汇运用（共10小题; 每小题1分, 满分10分） 第一节 根据句意，用括号中所给汉语提示或英语单词的适当形式填空。在横线上写出空缺处所填单词的正确形式。 36．The (递送) service by robots makes online‑shopping much faster. 37．When the smart machine breaks down, it will send out a (警示). 38．With the help of robotic systems, doctors in this hospital can complete operations (effective) than before. 39．Q-bot, the trusted robot helper, is very good at (pack) suitcases according to different weather and trip plans. 40．So far, hundreds of nanobots (develop) for medical research in the laboratory of Jiangsu Province. 第二节 阅读短文，从方框中选择适当的词并用其正确形式填空，使短文通顺完整，每个单词或短语仅用一次（其中一项为多余选项）。     abroad,  amazing,  artificial,  first,  more than,  understand Amy: Hi, Tom!

A group of high school students in southern China o 47 their answers, moving millions of people. Yu Yaxuan, a Chinese language teacher at Shenzhen Nanshan Foreign Language School (Group) in Guangdong province, recently collected 54 surveys from her students, each containing only one question: “If you had to choose one Chinese c 48 to prove you’re not AI, what would it be?” The answers surprised Yu and later impressed many people on the internet after a video about the exercise went viral, leading to heated discussion about the meaning of being human. Two students offered seemingly o 49 answers: “urgent” and “slow”. “Robots don’t understand why humans are always in a hurry,” one student wrote. “It takes 30 minutes for a hospital to give back test results, so why do patients check them every few minutes? Humans do not live in purely objective time. Our experience of time is s 50 by emotion.” Another student, surnamed Wu, didn’t agree. “When we think of speed and efficiency, we think of AI, yet humans long to slow down with those they care about,” Wu wrote. “AI is always pursuing speed and correct results, but I wish for humans to walk slowly, speak slowly and grow up slowly. I am willing to spend time on things that make life beautiful.” Other students chose words such as “doubt” and “finite”. “Will AI doubt its creator?” one student asked. Another wrote: “AI is infinite, but e 51 about me is finite—the knowledge I’ve g 52 , the people I’ve met, the stories I’ve heard, my life and my time. AI is valuable because it is infinite, while I am e 53 more precious because I am finite.” Other answers included “courage”, “faith”, “hate”, “r 54 ”, “love” and “hurt”. “What t 55 moves people may not be a single class, but the faint glimmers of humanity that digitalization can’t delete,” Yu said. 六、阅读表达（共 5 小题; 每小题 2分, 满分10分） 阅读短文，根据短文内容用英语回答问题，每题答案不超过6个词。 In recent years, AI technology has been used widely in our daily life. Is AI a useful tool for learning? Is it bad for students' ability to think? Here is what our students told us. Some students depend on AI too much. As a result, they don’t even know how to do the most simple things. However, I believe that AI can be a useful tool. My history teacher uses AI to help him plan lessons and make reading passages shorter. He also teaches us how to use AI in the right way. He shows us useful tips like turning notes into a study guide. That’s completely different from using it to write everything for us. In a word, it’s not the tool that’s the problem, but it’s how people use it. AI should help us students learn, not help us avoid learning. I believe that students who use AI for schoolwork are not learning. When they use AI, it just builds up an answer from the Internet and does not allow students to learn how to research a topic, understand articles, or learn by heart. Some students do not use their own minds when putting the results on their schoolwork. As a result, they have missed the chance to grow. What’s worse, AI may give some false information to students, and something terrible will happen. 56．Who thinks AI can be a useful tool for learning, Sally or Tom? 57．How does Sally’s teacher help them use AI better? 58．Why do some students miss the chance to grow, according to Tom? 59．What does Tom think AI may give students? 60．What do you think of using AI for learning? 七、书面表达（共1小题; 满分20分） 61．习近平总书记强调：“科技兴则民族兴，科技强则国家强。”假如你是李华，将参加学校“Technology Makes Life Better and Brighter”主题英语演讲比赛。请写一篇演讲稿，内容包括： 1.
