科技与创新专题 阅读理解C、D篇培优练(一) A组 C (2025·吉林长春二模)Online shopping often involves endless options and constantly changing discounts. A single search for running shoes can produce hundreds of results across multiple platforms, each promising the “best deal”. The holiday season brings excitement, but also plenty of decision-making exhaustion and troublesome nightmares. What if there is a tool that can hunt for the best prices, navigate (导航) endless sales and make sure your purchases arrive on time? The answer is AI agents, which are capable of autonomous reasoning and multistep problem-solving. Picture this: You instruct AI to find a sweater under $200 that's highly rated and will arrive by Sunday. In seconds, it scans websites, compares prices, checks reviews, confirms availability and places the order, all while you go about your day. Unlike traditional recommendation engines, the agents are built with machine learning and natural language processing. They learn from their interactions with the people using them and become smarter and more efficient over time from their collective interactions. Looking ahead, AI agents are likely to not only master personal shopping needs but also negotiate directly with corporate AI systems. They will not only learn your preferences but will likely be able to book tailored experiences, handle payments across platforms and so on. AI agents are moving beyond recommendations to autonomously carrying out complex tasks such as making refunds and approving pricing decisions. This development has already begun to reshape how businesses operate. Retailers (零售商) using AI agents are seeing measurable benefits. Since October 2024, data from an app's shopping index (指数) reveals that digital retailers using generative AI have achieved a 7% increase in average order profits and owed 17% of global orders to AI-driven personalized recommendations, targeted promotions and improved customer service. The nature of search and advertising is also undergoing a major shift. Meanwhile, AI-powered search tools deliver instant, context-aware responses, challenging traditional search engines and forcing advertisers to rethink their strategies. [语篇解读]　本文是一篇说明文。文章主要介绍了人工智能代理在网络购物时的作用，以及其对企业运营、搜索和广告等方面的影响。 1 2 3 4 1．What can be learned about online shopping from paragraph 1? A．It always works best in holiday seasons. B．It goes far beyond business principles sometimes. C．It frequently brings unpleasant shopping experiences. D．It usually provides the greatest platform for buying shoes. 答案：C 解析：细节理解题。根据第一段中的“Online shopping often involves endless options and constantly changing discounts... troublesome nightmares.”可知，网上购物常常意味着有无穷无尽的选择和不断变化的折扣，仅仅搜索一下跑鞋，就可能在多个平台上产生数百条结果，每个结果都承诺自己是“最划算的交易”；假期季节带来了兴奋感，但同时也带来了大量的决策疲劳和棘手的烦心事。这说明网上购物经常带来不愉快的购物体验。故选C。 1 2 3 4 2．What is paragraph 3 of the text mainly about? A．The present applications of AI agents. B．The potential advantages of AI agents. C．The increasing popularity of AI agents. D．The historical background of AI agents. 答案：B 1 2 3 4 解析：段落大意题。第三段讲与传统的推荐引擎不同，人工智能代理是基于机器学习和自然语言处理技术构建的，它们通过与使用者的互动来学习，并随着时间的推移，通过集体的互动，变得更加智能、高效；展望未来，人工智能代理不仅可能掌握个人的购物需求，而且还可能直接与公司的人工智能系统进行协商，它们不仅会了解消费者的偏好，还很可能能够预订量身定制的体验、处理跨平台的支付等。由此可知，本段主要介绍了人工智能代理的潜在优势。故选B。 1 2 3 4 3．Which is an impact of AI agents? A．Helping retailers earn more money. B．Updating traditional search engines. C．Tracking customers' private information. D．Replacing the existing advertising strategies. 答案：A 1 2 3 4 解析：细节理解题。根据第四段中的“Retailers using AI agents are seeing measurable benefits... improved customer service.”可知，使用人工智能代理的零售商正在看到显著的效益，使用生成式人工智能的数字零售商平均订单利润已增长了7%，且其全球 17%的订单都归功于由人工智能驱动的个性化推荐、有针对性的促销活动以及改善后的客户服务。由此可知，人工智能代理可以帮助零售商赚更多的钱。故选A。A项中的“earn more money”与文中的“a 7% increase in average order profits”是同义转换。 1 2 3 4 4．Which can be the best title for the text? A．Living a Quality Life with High Tech B．Reshaping Business via Search Engines C．Exploring the New World Wide and Far D．Transforming Online Shopping and Beyond 答案：D 1 2 3 4 解析：标题归纳题。文章开篇介绍了网上购物存在的问题，引出人工智能代理，接着讲述了人工智能代理在网购中的作用，还提及了人工智能代理对企业运营、搜索和广告等方面的影响。由此可知，文章主要讲述了人工智能代理给网上购物以及其他方面带来的变革。故D项“变革网上购物及其他领域”最适合作为本文标题。 1 2 3 4 语料积累 必备 单词 Para.1：nightmare n．噩梦，梦魇；可怕的经历，难以处理之事　purchase n．购买的东西，购买项目 Para.2：capable adj.有能力，有才能　scan v．浏览，粗略地读；细看，察看，审视，端详　availability n．可得性；空闲 Para.3：efficient adj.效率高的，有能力的　collective adj.集体的，共同的，共有的　negotiate v．谈判，磋商，协商；商定，达成(协议)　corporate adj.公司的 Para.4：measurable adj.有明显影响的，显著的；可测量的，可度量的　personalized adj.为某人特制(或特设)的 必备 短语 Para.2：in seconds片刻，瞬间　go about...做……，干…… Para.3：look ahead向前看，展望未来 D (2025·豫西北联盟第一次质检)Imagine looking through the Internet and seeing a famous star pop up.He says he's giving away brand-new phones.“Click the link below to claim yours now！”Do you click? Maybe.It looks and sounds like the star.But it's actually a deepfake—a false clip (片段) created by artificial intelligence (AI).Last October, this video tricked fans into sharing personal details.But a new tool, AntiFake, could help prevent such scams (欺诈). An AI model can learn to imitate someone's voice based on about 30 seconds of a speech.“It does this by creating something called an embedding.This is basically a series of numbers，”says Yu Zhiyuan, a PhD student in computer science at Washington University, whose team built AntiFake. People recognize voices by paying more attention to some frequencies of sound waves and less attention to other frequencies, but the AI model uses all frequencies to create good embeddings.AntiFake protects voice recordings by adding some noise to the frequencies people pay less attention to.That noise can mess up an AI model's ability to create a good embedding of the voice. Yu's team picked 600 deepfake clips that fooled both human listeners and voice-authentication (语音认证) systems, and then added AntiFake protection to the 600 voice clips those deepfakes had been based on.Next, the scientists sent the protected files back through the five deepfake AI models.This time, over 95% of the new deepfake samples no longer tricked people or machines. “This is an interesting and great new tool to defend against deepfakes，”says Shimaa Ahmed, an expert who wasn't involved in building AntiFake.“However, if my voice is my job, I'd like to have my voice as it is.” “This is actually a problem we want to address in the future，”Yu notes.Instead of adding noise, he thinks AntiFake could change the rhythm or tone of a voice.The voice would sound clear and unchanged to listeners.But it would contain carefully-hidden signals to trick deepfake AI models. [语篇解读]　本文是一篇说明文。文章介绍了一种名为AntiFake的可以预防深度伪造语音欺诈的新工具。通过向不太被注意的频率添加噪声，AntiFake能干扰AI模型生成的声音嵌入，从而有效预防语音被伪造。 5 6 7 8 5．How does AntiFake help prevent deepfake voice scams? A．By making AI models' embeddings damaged. B．By making voices sound noisy and annoying. C．By making voice recordings hard to imitate. D．By making voices difficult to identify and record. 答案：C 解析：细节理解题。根据第三段中的“AntiFake protects voice recordings by adding some noise to the frequencies...to create a good embedding of the voice.”可知，AntiFake通过向人们不太注意的频率上增加一些噪声来保护录音，这种噪声会干扰AI模型生成良好的声音嵌入的能力。由此可知，AntiFake是通过使录音难以模仿的方式帮助预防深度伪造语音欺诈的。故选C项。 5 6 7 8 6．What is paragraph 4 intended to show about AntiFake? A．Its development.　　　　 B．Its effectiveness. C．Its special design. D．Its working principle. 答案：B 5 6 7 8 解析：推理判断题。根据第四段最后一句“This time，over 95% of the new deepfake samples no longer tricked people or machines.”可知，在这些深度伪造所基于的600个语音片段上添加了AntiFake保护后，95%的取样无法骗过人们和语音识别机器。由此可推知，第四段旨在介绍AntiFake的效果。故选B项。 5 6 7 8 7．What's Shimaa Ahmed's attitude to AntiFake? A．Objective. B．Disappointed. C．Positive. D．Unclear. 答案：A 5 6 7 8 解析：观点态度题。根据第五段中的“This is an interesting and great new tool to defend against deepfakes” “However，if my voice is my job, I'd like to have my voice as it is.”可知，Shimaa Ahmed认为，AntiFake是一种有趣且极好的新工具，可以预防深度伪造。但是，如果她的声音就是她的工作，她希望她的声音可以保持原样。由此可推知，Shimaa Ahmed 对AntiFake的态度是客观的。故选A项。 5 6 7 8 8．Which of the following is a suitable title for the text? A．The Role of AI Models in Scams B．A New Tool to Prevent Voice Scams C．Impacts of Deepfake Voice Scams D．An Innovation for Identifying Voice Scams 答案：B 5 6 7 8 解析：标题归纳题。通读全文可知，本文主要介绍了一种名为AntiFake的可以预防深度伪造语音欺诈的新工具。通过向不太被注意的频率添加噪声，AntiFake能干扰AI模型生成的声音嵌入，从而有效预防语音被伪造。B项“一种防止语音欺诈的新工具”适合作为本文标题。故选B项。 5 6 7 8 语料积累 必备 单词 Para.1：brand-new adj.全新的，崭新的 Para.2：imitate v．模仿，仿效　basically adv.大体上，基本上 Para.3：frequency n．(声波或电磁波振动的)频率；发生率，出现率 Para.6：rhythm n．节律；节拍，节奏 熟词 生义 Para.1：claim v．常用义：宣称，声称，断言　文章义：认领，索取 必备 短语 Para.1：pop up突然出现　trick sb.into doing sth.诱使某人做某事 Para.3：mess up破坏，毁掉；弄脏，弄乱 长难句 分析 Yu's team picked 600 deepfake clips that fooled both human listeners and voice-authentication systems，and then added AntiFake protection to the 600 voice clips those deepfakes had been based on.(Para.4) 分析：本句为由and连接的并列复合句。第一个分句中that引导定语从句，修饰先行词deepfake clips；第二个分句中those...on为省略关系词的定语从句，先行词为the 600 voice clips。 译文：Yu的团队挑选了600个能够骗过人类听众和语音认证系统的深度伪造片段 ，然后在这些深度伪造所基于的600个语音片段上添加了AntiFake保护。 B组 C (2025·四川蓉城名校联盟考试)For years, Egyptologists have hotly debated how the massive pyramids (金字塔) of ancient Egypt (埃及) were built more than 4，000 years ago.Now, a team of engineers and geologists bring a new theory to the table—a water lift device that would have floated the heavy stones up through the middle of Egypt's oldest pyramid using stored water. Ancient Egyptians built the Step Pyramid for Pharaoh Djoser in the 27th century BCE, and it was the tallest structure at the time, coming in at about 62 meters tall.But how exactly the structure was erected，with a number of stones weighing in at 300 kilograms, has remained a centuries-old mystery, according to the study published Monday in the journal PLOS One. “ Many detailed publications have discussed pyramid-building procedures and provided real examples, but these usually focus on more recent, better-documented, and smaller pyramids of the Middle and New Kingdoms，” said lead author Dr.Xavier Landreau, CEO of Paleotechnic, a privately owned research institute in Paris that studies ancient technologies. “The techniques involved could include ramps (活动坡道)，cranes (起重机)，or a combination of these methods，” he added in an email.“But what about the Old Kingdom pyramids, which are much bigger? While human strength and ramps may be the only construction force for small structures, other techniques may have been used for large pyramids.” Using a combined approach, the new paper was the first to report a system matching the Step Pyramid's internal architecture, the authors wrote. A complex water treatment system drawing upon local resources could have created a water-powered elevator within the pyramid's internal vertical passage.Some type of float would have raised the heavy stones up the middle of the pyramid, according to the study. [语篇解读]　本文是一篇说明文。多年来，埃及学家一直在激烈讨论古埃及金字塔是如何建造的。如今，一组工程师和地质学家提出了一种新的理论——古埃及人可能使用了一种水升装置，通过存储的水来升起重石。 1 2 3 4 1．What does the underlined word “erected” in paragraph 2 probably mean? A．Changed. B．Designed. C．Built. D．Destroyed. 答案：C 解析：词义猜测题。根据画线词上文的“Ancient Egyptians built the Step Pyramid...at about 62 meters tall.”和下文的“with a number of stones weighing in at 300 kilograms, has remained a centuries-old mystery”可知，古埃及人在公元前27世纪建造了阶梯金字塔，这座由重达300千克的石头组成的建筑大约有62米高，是当时最高的建筑。再结合下文可知，全文围绕金字塔是如何建造的这一话题展开，画线词应意为“建造”。故选C项。 1 2 3 4 2．Which may play a role in building small pyramids according to Dr.Xavier Landreau? A．People and ramps. B．Ramps and cranes. C．People and cranes. D．Water and ramps. 答案：A 解析：细节理解题。根据第四段中的“human strength and ramps may be the only construction force for small structures”可知，人力和活动坡道在建造小型金字塔中起作用。故选A项。 1 2 3 4 3．What is the main advantage of the water lift device in building pyramids? A．It simplifies the use of ramps. B．It helps to make heavy stones raised. C．It increases the weight of the stones. D．It uses some resources for treatment. 答案：B 解析：细节理解题。根据最后一段可知，古埃及人可能利用了复杂的水处理系统，在金字塔内部的垂直通道内创造了一个水力升降机。根据这项研究，某种类型的漂浮装置可能会将这些沉重的石头提升到金字塔的中间。故选B项。 1 2 3 4 4．What is the best title for the text? A．Water Lift Theory: A New View on Pyramid Construction B．Recent Research on the Stories of Egypt's Small Pyramids C．A Historical Debate: Egypt's Pyramid Construction Secrets D．Exploring Ancient Egyptian Pyramid Construction Mysteries 答案：A 1 2 3 4 解析：标题归纳题。文章介绍了一种新的金字塔建造理论——水升装置理论，并解释了古埃及大型金字塔的建造方法。故A项为本文最佳标题。 语料积累 必备 单词 Para.2：mystery n．神秘的事物，奥秘 Para.3：publication n．发行，出版物　procedure n．步骤，程序　privately adv.私下地；秘密地 Para.6：vertical adj.垂直的，直立的 必备 短语 Para.1：bring sth.to the table为(讨论、项目等)作出贡献 Para.6：draw upon利用，依靠，凭借 D (2025·浙江杭州质检)A few days ago, I watched a video of myself talking in perfect Chinese.I've been studying the language on and off for only a few years, and I'm far from fluent.But there I was pronouncing each character just as a native speaker would.“My favorite food is sushi，”I said—wo zui xihuan de shiwu shi shousi. I'd created the video using software from a Los Angeles-based artificial intelligence start-up. The technology, which only needs a single selfie and a script to generate deepfake videos of real people“saying”almost anything, is a testament (证明) to the advancements in AI language tools.This got me thinking about the declining interest in language learning with fewer students enrolling in foreign language courses and the decrease of English proficiency among young people in some places. AI translation, integrated into social media and messaging platforms, seems to be everywhere.Even language-learning apps are using AI-generated content in their marketing.However, language translation is an art rather than a science.Something enormous will be lost in exchange for that convenience.As Anne, a Chinese translator, said, “Building a ladder between widely different languages, such as Chinese and English, is sometimes as difficult as a doctor building a bridge in a patient's heart.” Language learning fosters cultural competency, a skill that AI cannot simply copy.Learning a different way to speak, read, and write helps people discover new ways to see the world.No machine can replace such a profound human experience.Deborah Cohn, a language professor, emphasizes that language learning is actually about understanding and connecting with different cultures.Instead of abandoning language courses in favor of AI, some educators advocate for emphasizing the intercultural aspects of language learning.Paula Krebs of the MLA (Modern Language Association) points out that even with a “universal translator”， sometimes, the greater meaning of people's utterances (言辞) remains a mystery. In essence, while AI language tools offer convenience, they lack the depth and cultural insight that comes from human language learning.The challenge and beauty of learning a language are in understanding the cultural tapestry (织锦) that weaves through words, something AI has yet to achieve. [语篇解读]　本文是一篇说明文。学习一门语言能使人们有效进行跨文化交流，人工智能语言工具为语言学习提供了便利，但它们缺乏人类语言学习的深度和文化洞察力。 5 6 7 8 5．Why does the author give the example in paragraph 1? A．To promote the language software. B．To show off her Chinese language skills. C．To prove learning a language is a wasted effort. D．To encourage critical thinking about AI language tools. 答案：D 解析：推理判断题。 作者在第一段介绍了自己说中文的视频，然后在第二段具体解释了该视频的制作方法以证明人工智能语言工具的进步，接着说“This got me thinking about the declining interest in language learning...young people in some places.(这让我想到了语言学习兴趣的下降，注册学习外语课程的学生越来越少，一些地方的年轻人的英语熟练度也在下降)”。由此可知，该视频激发了作者对人工智能语言工具的批判性思考。故选D。 5 6 7 8 6．What can we learn from paragraph 3? A．AI translation deserves more attention. B．Language apps play a key role in marketing. C．Language translation is far beyond technology. D．Learning a different language is an uphill battle. 答案：C 5 6 7 8 解析：细节理解题。第三段前两句讲人工智能翻译似乎无处不在；接着用however引起转折，说明语言翻译是一门艺术而不是一门科学。由此可知，语言翻译远远超出了技术的范畴。故选C。 5 6 7 8 7．What is the key benefit of learning a language according to the text? A．Better digital literacy. B．Improved translation skills. C.Deeper cultural confidence. D．Effective intercultural interaction. 答案：D 5 6 7 8 解析：细节理解题。第四段第一句讲语言学习培养文化能力，这是人工智能无法简单复制的技能。根据第四段中Deborah Cohn强调的“language learning is actually about understanding and connecting with different cultures”可知，语言学习实际上是关于理解和联系不同的文化。另外，第四段还提到一些教育家主张强调语言学习的跨文化方面。综上可知，学习一门语言的主要好处是使人们有效地进行跨文化交流。故选D。 5 6 7 8 8．What does the author imply in the last paragraph? A．AI language tools offer convenience. B．AI facilitates language learning in terms of culture. C．AI is far from perfect in helping language understanding. D.AI has achieved success in the development of language learning tools. 答案：C 5 6 7 8 解析：推理判断题。 最后一段提到，本质上，虽然人工智能语言工具提供了便利，但它们缺乏人类语言学习的深度和文化洞察力。学习一门语言的挑战和美妙之处在于理解贯穿于文字之中的文化织锦，这是人工智能尚未实现的。由此可知，人工智能在帮助理解语言方面还远远不够完美。故选C。 5 6 7 8 语料积累 必备 单词 Para.2：start-up n．新创公司，初创企业　selfie n．自拍照　script n．剧本，电影剧本，广播(或讲话等)稿；脚本(程序)(计算机的一系列指令)　proficiency n．熟练，精通 Para.4：foster v．促进，助长，培养，鼓励 熟词 生义 Para.1：character n．常用义：(人、集体的)品质，性格，(地方的)特点，特性　文章义：(书写、印刷或计算机上的)文字，字母，符号 必备 短语 Para.1：on and off不时地，断断续续地　far from几乎相反，远非 Para.2：enroll in...注册参加…… Para.3：integrate...into...使合并，使结合(从而变得更有效)　in exchange for...作为……的交换 Para.4：in favor of 赞成，认可；主张，支持　advocate for主张，支持 Para.5：in essence本质上，实质上 感谢您的观看 $
