First introduced in the 1980s in role-playing games, avatars have evolved from simple 2D images to complex 3D characters that can move, speak, and even express emotions. Today, people use avatars across a wide range of platforms, from social media and messaging apps to virtual reality environments. One of the main benefits of avatars is that they allow people to explore different aspects of their identity. You can be whoever you want to be online—change your age, gender, appearance, and even personality. This can be especially beneficial for people who feel restricted by their real-life identities, such as those facing social anxiety or discrimination. Avatars provide a safe space for self-expression without the fear of judgment. However, avatars also bring significant challenges. The line between virtual identity and real identity can become blurred, especially for heavy users who spend most of their time in virtual worlds. Some people start to prefer their virtual identities to their real ones, leading to problems in real-life relationships and daily functioning. There is also the risk of identity deception, as people can use avatars to hide their true identities and engage in harmful behaviors like cyberbullying or online fraud. Despite these risks, many experts believe that avatars will play an increasingly important role in the future of digital interaction. With the development of metaverse technology, avatars may soon become our primary representatives in digital spaces, attending meetings, social events, and even educational classes on our behalf. The key to benefiting from this technology is to use it responsibly, maintaining a healthy balance between virtual and real-life experiences. 1. What can we learn about the evolution of avatars? A. They were first used in social media platforms in the 1990s. B. They have developed from simple 2D images to complex 3D characters. C. They can now fully replace real people in all aspects of life. D. They were initially designed to prevent online fraud and deception. 2. What is the main benefit of avatars mentioned in paragraph 2? A. They allow people to explore different aspects of their identity. B. They help people improve their social skills in real life. C. They provide free entertainment for people of all ages. D. They make online communication more efficient than face-to-face talks. 3. The underlined word "blurred" in paragraph 3 probably means ________. A. clearly defined B. completely disappeared C. difficult to distinguish D. strongly emphasized 4. What is the author's attitude towards the future of avatars? A. Doubtful B. Optimistic C. Negative D. Unconcerned 5. What is the main purpose of the text? A. To criticize the negative impacts of avatars on young people. B. To introduce the development, benefits and risks of avatars. C. To encourage people to abandon real-life communication and use avatars more. D. To explain why avatars are more popular among young people than adults. 七、七选五 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 How to Use Avatars Responsibly Online Avatars have become an important part of our digital lives, allowing us to express ourselves creatively and connect with others in virtual spaces. 1 Here are some tips for using avatars responsibly: ●Be aware of the information you reveal. While avatars can help protect your privacy, you should still be careful about the personal information you share online. 2 Avoid revealing details like your real name, address, phone number, or financial information to people you only know through virtual interactions. ● 3 It can be easy to forget that there is a real person behind every avatar you interact with online. Treat others in virtual spaces with the same respect you would show them in real life. Avoid using your avatar to engage in harmful behaviors like bullying, harassment, or deception. ●Maintain a healthy balance between virtual and real life. While virtual worlds can be fun and engaging, it's important not to let them take over your real life. 4 Make sure you are still spending time with real friends and family, pursuing hobbies outside of the digital world, and taking care of your physical and mental health. ●Understand the risks of virtual identity deception. __5 Be cautious when interacting with strangers online, and remember that people may not be who they say they are through their avatars. If something feels suspicious or uncomfortable, trust your instincts and end the interaction. By following these guidelines, you can enjoy the benefits of avatars while minimizing the risks, making your online experiences safe, positive, and rewarding. A. Treat others with respect. B. Avatars can help you make more friends online. C. However, they also come with significant risks if used improperly. D. Set limits on the amount of time you spend in virtual worlds each day. E. Remember that avatars are only representations of real people, not the people themselves. F. The avatar you choose can say a lot about your personality and interests. G. Not everyone uses avatars honestly, and some people use them to deceive others for personal gain. 1、 七选五（2026年全国I卷真题·AI赋能博物馆主题） 阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。 Museums, once quiet places filled with history, are now full of digital excitement. By using machine learning and advanced algorithms (算法), these institutions are creating personalized visitor journeys, protecting delicate collections, and revealing hidden stories. 36 AI transforms a standard museum trip into a personalized and interactive adventure. Smart recommendation engines analyze data such as exhibit popularity and visitors' past behavior to suggest specific exhibits and events, making each visit unique and surprising. 37 These digital assistants engage visitors in dynamic conversations and offer context-sensitive insights that deepen understanding and satisfy curiosity. Beyond visitor interaction, AI plays a crucial role in preserving priceless artworks. Since the exhibits in museums sustain natural decay (破损) over time, early detection is vital. AI can help identify the slightest signs of decay, such as cracks or discoloration, which are often invisible to the human eye. 38 Moreover, by predicting future decay patterns, AI helps museums take preventive measures and improve preservation strategies. AI also significantly enhances the educational value of museums, particularly for children and families. 39 For instance, interactive exhibits powered by AI can adjust their content and difficulty level based on the users' preferences and responses. This adaptability ensures that complex historical concepts become accessible and engaging for young minds. Looking ahead, the rapid advancement of AI promises both exciting possibilities and ethical (伦理的) challenges. Museums are working together with AI ethicists to develop fair algorithms. 40 Strict policies should be established to protect visitors' information. A. This capability allows for timely restoration B. Visitor data collection also raises privacy issues C. In short, AI is redefining the museum in all respects D. It tailors learning experiences to different age groups and learning styles E. Museums are not only places to store artworks, but also spaces for learning F. Furthermore, AI-powered virtual guides are replacing traditional tour guides G. AI is changing this by using image recognition technology to analyze exhibits 2、 阅读理解（2025年浙江卷真题·人工智能伦理主题） Artificial intelligence (AI) researchers have long dreamed of tools to supercharge science—asking novel questions, designing and running experiments. Recently, large language models (LLMs) have made discoveries that some AI developers claim have inched us closer to that future. But how do you test whether an AI model can truly do science? For answers, researchers turn to benchmarks (基准): standardized sets of questions or tasks that help measure an AI’s efficiency and reliability and compare it against other models. But the complexity of science makes assessing their aptitude especially challenging. As Hao Peng, a computer scientist at the University of Illinois Urbana-Champaign, puts it: "Models have all this knowledge. Do they know how to use it?" Dozens of new science-focused benchmarks have emerged over the past year to answer that question, but scientists have yet to settle on a single best approach. One of the most popular, published in Nature, is Humanity’s Last Exam (HLE). It uses 2500 questions drawn from "the frontier of human knowledge" to put LLMs through their paces. One, for example, asks how many types of sensory receptors the human skin contains. "We wanted a diverse data set that only experts who have been working on a field for a long time can answer," says Long Phan, a research engineer with the HLE’s developer. Since the HLE first appeared as a preprint in January 2025, the benchmark has become an important proving ground for LLMs and HLE scores are now a common talking point for AI companies seeking to highlight the capabilities of their products. At the HLE’s launch, the leading developer OpenAI’s AI model won the best score at a mere 8.3%. Earlier this month, Google claimed that its latest reasoning model for science, called Gemini 3 Deep Think, had achieved a new record HLE score of 48.4%. But some scientists argue that many of the HLE’s questions test for little-known or even useless knowledge, rather than an ability to do meaningful research. A Nature editorial accompanying the HLE’s publication also raised this issue: "We think that more scientists should be asking: What would it take to develop an AI benchmark that truly measures expert-level thinking?" 1. What does the underlined word "aptitude" in paragraph 2 probably mean? A. Knowledge B. Performance C. Intelligence D. Progress 2. What does Long Phan stress about HLE? A. Its topic diversity B. Experts’ involvement in it C. The expertise of its data set D. Its data-backed popularity 3. What is paragraph 4 mainly about? A. HLE’s role as a key AI test B. Companies’ use of HLE C. HLE scores of leading AI models D. The process of HLE’s launch 4. By sharing its view, the Nature editorial aimed to ________. A. back the current testing B. express concern over HLE C. propose a workable solution D. predict future AI benchmarks 4 / 8 学科网（北京）股份有限公司 $ 分层作业 Unit 4 Period 1 Topic Talk & Avatars 目 录 A组 巩固过关 B组 能力进阶 C组 思维拔高 拓展 链接高考 一、词汇拼写：根据句意及首字母或汉语提示填写单词 【答案】 1. avatars 2. intelligence 3. complex 4. enables 5. sensible 6. identity 7. addicted 8. variety 9. cheat 10. convenience 二、短语互译 【答案】 1. virtual world 2. a variety of 3. be known as 4. instead of 5. look forward to 6. 沉迷于 7. 即时通讯 8. 数字身份 9. 从更积极的角度 10. 尝试；体验 三、单句语法填空。 【答案】 1. would become 考查过去将来时：表示从过去的视角看将要发生的动作。 2. enables 考查主谓一致：主语为单数名词use，谓语动词用第三人称单数形式。 3. would design / was going to design 考查过去将来时：从过去的视角看计划将要做的事。 4.

While avatars can help protect your privacy, you should still be careful about the personal information you share online. 2 Avoid revealing details like your real name, address, phone number, or financial information to people you only know through virtual interactions. ● 3 It can be easy to forget that there is a real person behind every avatar you interact with online. Treat others in virtual spaces with the same respect you would show them in real life. Avoid using your avatar to engage in harmful behaviors like bullying, harassment, or deception. ●Maintain a healthy balance between virtual and real life. While virtual worlds can be fun and engaging, it's important not to let them take over your real life. 4 Make sure you are still spending time with real friends and family, pursuing hobbies outside of the digital world, and taking care of your physical and mental health. ●Understand the risks of virtual identity deception. __5 Be cautious when interacting with strangers online, and remember that people may not be who they say they are through their avatars.

By using machine learning and advanced algorithms (算法), these institutions are creating personalized visitor journeys, protecting delicate collections, and revealing hidden stories. 36 AI transforms a standard museum trip into a personalized and interactive adventure. Smart recommendation engines analyze data such as exhibit popularity and visitors' past behavior to suggest specific exhibits and events, making each visit unique and surprising. 37 These digital assistants engage visitors in dynamic conversations and offer context-sensitive insights that deepen understanding and satisfy curiosity. Beyond visitor interaction, AI plays a crucial role in preserving priceless artworks. Since the exhibits in museums sustain natural decay (破损) over time, early detection is vital. AI can help identify the slightest signs of decay, such as cracks or discoloration, which are often invisible to the human eye. 38 Moreover, by predicting future decay patterns, AI helps museums take preventive measures and improve preservation strategies. AI also significantly enhances the educational value of museums, particularly for children and families. 39 For instance, interactive exhibits powered by AI can adjust their content and difficulty level based on the users' preferences and responses. This adaptability ensures that complex historical concepts become accessible and engaging for young minds. Looking ahead, the rapid advancement of AI promises both exciting possibilities and ethical (伦理的) challenges. Museums are working together with AI ethicists to develop fair algorithms. 40 Strict policies should be established to protect visitors' information. A. This capability allows for timely restoration B. Visitor data collection also raises privacy issues C. In short, AI is redefining the museum in all respects D.

B 【解析】 36题：第一段总体介绍AI给博物馆带来的多方面变化，C选项"简而言之，人工智能正在从各个方面重新定义博物馆"是对首段内容的总结，起到承上启下的作用，符合语境。 37题：本段讲AI提升游客体验，空前讲智能推荐引擎的功能，空后讲"这些数字化助手"的功能，F选项"此外，由人工智能驱动的虚拟导游正在取代传统导游"自然引出后文的"数字化助手"，逻辑连贯。 38题：本段讲AI在文物保护方面的作用，空前提到AI能识别肉眼看不到的细微破损迹象，A选项"这种能力使得及时修复成为可能"承接上文的识别功能，符合逻辑。 39题：本段讲AI提升博物馆教育价值，空后举例说明AI互动展品可以根据用户偏好调整内容和难度，D选项"它能根据不同的年龄群体和学习风格量身定制学习体验"是对后文例子的总括，符合语境。 40题：最后一段讲AI带来的伦理挑战，空后提到要制定严格政策保护游客信息，B选项"游客数据收集也引发了隐私问题"自然引出后文的隐私保护内容，符合逻辑。 2、 阅读理解（2025年浙江卷真题·人工智能伦理主题） Artificial intelligence (AI) researchers have long dreamed of tools to supercharge science—asking novel questions, designing and running experiments. Recently, large language models (LLMs) have made discoveries that some AI developers claim have inched us closer to that future. But how do you test whether an AI model can truly do science? For answers, researchers turn to benchmarks (基准): standardized sets of questions or tasks that help measure an AI’s efficiency and reliability and compare it against other models. But the complexity of science makes assessing their aptitude especially challenging. As Hao Peng, a computer scientist at the University of Illinois Urbana-Champaign, puts it: "Models have all this knowledge. Do they know how to use it?" Dozens of new science-focused benchmarks have emerged over the past year to answer that question, but scientists have yet to settle on a single best approach. One of the most popular, published in Nature, is Humanity’s Last Exam (HLE). It uses 2500 questions drawn from "the frontier of human knowledge" to put LLMs through their paces. One, for example, asks how many types of sensory receptors the human skin contains. "We wanted a diverse data set that only experts who have been working on a field for a long time can answer," says Long Phan, a research engineer with the HLE’s developer. Since the HLE first appeared as a preprint in January 2025, the benchmark has become an important proving ground for LLMs and HLE scores are now a common talking point for AI companies seeking to highlight the capabilities of their products. At the HLE’s launch, the leading developer OpenAI’s AI model won the best score at a mere 8.3%. Earlier this month, Google claimed that its latest reasoning model for science, called Gemini 3 Deep Think, had achieved a new record HLE score of 48.4%. But some scientists argue that many of the HLE’s questions test for little-known or even useless knowledge, rather than an ability to do meaningful research. A Nature editorial accompanying the HLE’s publication also raised this issue: "We think that more scientists should be asking: What would it take to develop an AI benchmark that truly measures expert-level thinking?" 1. What does the underlined word "aptitude" in paragraph 2 probably mean? A. Knowledge B. Performance C. Intelligence D. Progress 2. What does Long Phan stress about HLE? A. Its topic diversity B. Experts’ involvement in it C. The expertise of its data set D. Its data-backed popularity 3. What is paragraph 4 mainly about? A. HLE’s role as a key AI test B. Companies’ use of HLE C. HLE scores of leading AI models D. The process of HLE’s launch 4. By sharing its view, the Nature editorial aimed to ________. A. back the current testing B. express concern over HLE C. propose a workable solution D. predict future AI benchmarks 答案：1. B 2. C 3. A 4. B 【解析】 1. 词义猜测题：根据第二段上下文，基准测试用于衡量AI的效率和可靠性，而科学的复杂性让评估AI做科学研究的"能力/表现"格外困难，aptitude意为"能力，表现"，故选B。 2. 细节理解题：根据第三段Long Phan的话"We wanted a diverse dataset that only experts who have been working on a field for a long time can answer"可知，他强调HLE的数据集只有深耕领域的专家才能解答，突出数据集的专业性，故选C。 3. 段落大意题：第四段主要介绍HLE自发布以来已经成为大语言模型的重要验证平台，HLE分数是AI公司展示产品能力的通用依据，说明HLE作为核心AI测试平台的作用，故选A。 4. 推理判断题：根据最后一段《自然》社论的内容"We think that more scientists should be asking: What would it take to develop an AI benchmark that truly measures expert-level thinking?"可知，社论对HLE现存的问题表达担忧，呼吁学界思考如何开发真正能测量专家级思维的AI基准，故选B。 4 / 8 学科网（北京）股份有限公司 $
