Paper, printing, electricity and the Internet all began as someone's idea, and each of them changed the way people live. 每天我们都在使用曾经看似不可能的东西。纸、印刷术、电和互联网都始于某个人的想法，而它们每一个都改变了人们的生活方式。 Take paper as an example. Before paper was invented, people in China wrote on bamboo pieces or silk. Bamboo was heavy and silk was expensive. When paper appeared, knowledge became easier to keep and carry, and more people could afford to learn to read. 以纸为例。在纸被发明之前，中国人把字写在竹片或丝绸上。竹片很重，丝绸很贵。纸出现后，知识变得更容易保存和携带，也有更多人负担得起读书识字。 Printing went one step further. With printing, a book no longer had to be copied by hand, so ideas could travel faster than ever. Centuries later, the Internet did something similar: it made information reach almost every corner of the world in seconds. 印刷术又向前迈进了一步。有了印刷术，书不必再靠手抄，思想得以以前所未有的速度传播。几个世纪后，互联网做了类似的事：它让信息在几秒钟内到达世界的几乎每一个角落。 Not every invention is famous, however. A better water pump, a stronger bicycle light or a cheaper way to store food can improve daily life just as much. Great inventions do not always look great at first; most of them simply solve a real problem for ordinary people. 然而，并非每一项发明都很有名。一个更好的水泵、一盏更亮的自行车灯，或一种更便宜的储存食物的方法，同样能改善日常生活。伟大的发明起初并不总是显得伟大；它们中的大多数只是为普通人解决了一个真实的问题。 Inventions also change as people use them. The first bicycles had no pedals, and the first phones could only make calls. Users kept finding new needs, and inventors kept answering them. In this way, a simple idea can grow into something that nobody could have imagined at the start. 发明也会随着人们的使用而改变。最早的自行车没有脚踏板，最早的手机只能打电话。使用者不断发现新的需求，发明者不断作出回应。就这样，一个简单的想法可以成长为一开始没有人能想象的东西。 【长难句分析】 1. 原句：Before paper was invented, people in China wrote on bamboo pieces or silk. 翻译：在纸被发明之前，中国人把字写在竹片或丝绸上。 重点：Before 引导时间状语从句，用一般过去时；was invented 为被动语态。 2. 原句：With printing, a book no longer had to be copied by hand, so ideas could travel faster than ever. 翻译：有了印刷术，书不必再靠手抄，思想得以以前所未有的速度传播。 重点：no longer 意为“不再”；have to be done 结构；so 引导结果状语从句；than ever 与比较级连用。 3. 原句：Great inventions do not always look great at first; most of them simply solve a real problem for ordinary people. 翻译：伟大的发明起初并不总是显得伟大；它们中的大多数只是为普通人解决了一个真实的问题。 重点：not always 表示部分否定；分号连接两个并列分句；solve a problem for sb. 意为“为某人解决问题”。 【重难词汇梳理】 1. invent /ɪnˈvent/ v. 发明 6. afford /əˈfɔːd/ v. 负担得起 2. invention /ɪnˈvenʃn/ n. 发明 7. century /ˈsentʃəri/ n. 世纪 3. bamboo /ˌbæmˈbuː/ n. 竹子 8. pump /pʌmp/ n. 泵 4. silk /sɪlk/ n. 丝绸 9. store /stɔː(r)/ v. 储存 5. knowledge /ˈnɒlɪdʒ/ n. 知识 10. solve /sɒlv/ v. 解决 Passage2 Drones: Helpers in the Sky English 中文翻译 A drone is a small aircraft without a pilot on board. At first, drones were mostly used by armies. Today, however, they have become useful helpers in many parts of our lives. 无人机是一种机上没有飞行员的小型飞行器。起初，无人机多用于军队。然而今天，它们已经成为我们生活许多方面的有用帮手。 In the countryside, farmers use drones to spray water or medicine over their fields. A drone can cover a large area in a short time, which saves both time and water. In cities, drones deliver medicine to hospitals and help firefighters find people in thick smoke. 在乡村，农民用无人机给田地喷洒水或药液。一架无人机能在短时间内覆盖大片区域，这既省时又省水。在城市，无人机为医院运送药品，还能帮助消防员在浓烟中找到人。 Drones are also helpful after disasters. When an earthquake breaks roads, a drone can fly over the damaged area and send back pictures. Rescue teams can then decide where to go first, without putting themselves in danger. 无人机在灾后也很有用。当地震破坏了道路，无人机可以飞越受损区域并传回图像。救援队随后可以决定先去哪里，而不用让自己身处危险之中。 Still, drones bring problems. They may hit birds, fall on people, or film others without permission. That is why many countries have made rules about where and when drones can fly. Used carefully, these small machines can make our world safer and more convenient. 不过，无人机也带来问题。它们可能撞到鸟、掉落到人身上，或未经允许拍摄他人。正因如此，许多国家制定了关于无人机飞行地点和时间的规则。只要谨慎使用，这些小型机器可以让我们的世界更安全、更便利。 For young people, drones are more than toys. Learning to fly one safely teaches patience, careful planning and respect for rules. Some students even build their own drones and test them in competitions. Who knows? The next great use of drones may come from a classroom like yours. 对年轻人来说，无人机不只是玩具。学会安全地操控无人机，能培养耐心、周密计划和对规则的尊重。有些学生甚至自己制作无人机，并在比赛中测试。谁知道呢？无人机的下一个伟大用途，也许就来自像你这样的课堂。 【长难句分析】 1. 原句：A drone can cover a large area in a short time, which saves both time and water. 翻译：一架无人机能在短时间内覆盖大片区域，这既省时又省水。 重点：which 引导非限制性定语从句，指代前面整句话；both...and... 连接并列成分。 2. 原句：When an earthquake breaks roads, a drone can fly over the damaged area and send back pictures. 翻译：当地震破坏了道路，无人机可以飞越受损区域并传回图像。 重点：When 引导时间状语从句；send back 意为“传回、送回”；damaged 为过去分词作定语。 3. 原句：That is why many countries have made rules about where and when drones can fly. 翻译：正因如此，许多国家制定了关于无人机飞行地点和时间的规则。 重点：That is why... 意为“这就是……的原因”；about 后接 where/when 引导的宾语从句。 【重难词汇梳理】 1. drone /drəʊn/ n. 无人机 6. firefighter /ˈfaɪəfaɪtə(r)/ n. 消防员 2. aircraft /ˈeəkrɑːft/ n. 飞行器，飞机 7. disaster /dɪˈzɑːstə(r)/ n. 灾难 3. army /ˈɑːmi/ n. 军队 8. rescue /ˈreskjuː/ n. & v. 营救 4. spray /spreɪ/ v. 喷洒 9. permission /pəˈmɪʃn/ n. 允许 5. deliver /dɪˈlɪvə(r)/ v. 递送 10. convenient /kənˈviːniənt/ adj. 便利的 Passage1 Battles over sales Livestreamer Dong Yuhui wins hearts over a controversy “顶流”主播董宇辉的上升之路 Dong Yuhui, a 30-year-old livestreaming (直播) host for East Buy (东方甄选), found himself in an online controversy (争议) that began on Dec 5. East Buy, a subsidiary (子公司) of New Oriental Education (新东方教育科技集团), said that many of the things Dong said in his livestreams were written by the East Buy team, not by himself. The then-CEO, Sun Dongxu, criticized Dong and the team, which made Dong’s fans upset. Surprisingly, this controversy made Dong even more popular. In just one week, his Douyin followers (关注者) increased by over 3 million, while East Buy lost more than 2 million followers. Sun was no longer the CEO, and Dong became vice president (副总裁) of New Oriental’s cultural and tourism business. Despite his rising fame, Dong remains humble. “I am not good-looking or tall; I don’t know why I have so many supporters,” he said. However, Xu Hanze, an associate professor (副教授) at Nanjing University of Aeronautics and Astronautics (南京航空航天大学), believes that Dong got more attention because of his talent and intelligence, thanks to his habit of reading extensively. In the age of consumerism (消费主义), Dong does not trick consumers into buying unnecessary products, but encourages them to be rational (理性的) when shopping online. He also puts more effort into educational activities and events to help farmers. He believes that people should not wish to be the next Dong Yuhui. “I want to tell other young livestreamers that they do not need to be me, as each story is moving in its own way.” He went on to say that people are not products made on manufacturing lines, and that diversity (不同) is what makes people special.          China Daily 1．What raised the controversy?

Passage3 On January 28, 2025, something amazing happened on Chinese TV. During the CCTV Spring Festival Gala, a very popular TV show, people saw a dance called “Yang BOT”. Famous movie director Zhang Yimou made this show. This special show mixed an old Chinese dance called “yangko” with new robot technology. Yangko is a joyful and traditional dance from the north of China. People often dance it during holidays. In the show, humanoid robots (robots shaped like humans) who wear bright and colorful clothes danced yangko. The robots waved colorful handkerchiefs (手帕) very fast and made interesting shapes together. These robots were developed by Unitree (宇树科技), a Chinese robotics company. This was not Unitree’s first success. Back in 2021, Unitree made robot cows named “Ben Ben”. These robot cows danced behind the famous singer Andy Lau. They moved in a funny way but the performance weren’t very smooth then. But this time, the Yang BOT robots were much better! They danced through AI and used laser navigation (激光导航). This helped them move safely and quickly, even on a stage that wasn’t flat. It was a big step forward in robot technology. Director Zhang Yimou said, “This dance isn’t just fun. It shows how new technology can help old traditions become new and exciting again.” Thanks to these improvement, the robots won the hearts of millions. On social media, topics like “Robot Yangko” became hot quickly. Young people thought it was “cool”. Older people enjoyed the humor and happiness it brought to them. The Yang BOT show is a great mix of China’s technological progress and cultural pride. One fan said, “It’s like watching the future and the past dance together!” Many people, especially Chinese people living in other countries, wrote messages on CCTV’s website. They said the show made them feel very proud to be Chinese. It shows China’s confidence and pride. 9．What made the Yang BOT show special? A．It was created by the famous movie director Zhang Yimou. B．The robots wore more colorful clothes than human dancers. C．Human - shaped robots showed a traditional Chinese dance. D．The robots could dance every form of Yangko during holidays. 10．Why were the Yang BOT robots better than the “Ben Ben” robot cows? A．They used AI to design more beautiful dances. B．They used new technology to change clothes faster. C．They used laser navigation to move safely on stages. D．They used bright lights to make the dance more colorful. 11．What can be learned from the underlined sentence? A．The robots learned to understand human hearts. B．Millions of people bought robots after the show. C．Improvements helped robots dance with famous people. D．The new technology made people love the robot performance. 12．Which one of the following can be the best title of the passage? A．Unitree’s Success in Making Pleasing Robots B．How the Spring Festival Gala Became More Popular C．Robot Technology: The Future of Stage Performances D．Dancing Robots Bring New Life to Traditional Culture Passage4 In the summer of 1978, an English man named Steven was driving his tractor through a field of wheat when he discovered something strange. Some of his wheat was lying on the ground. The flattened wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. Three years later, a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger—nearly 15 meters across. In the Same year, another English farmer discovered three circles of flattened wheat on his land—one large circle between two small circles. During the following years, farmers in England found circles in their fields more and more often. The circles are called “crop circles” because they usually appear in fields of wheat or corn. The wheat in the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. What cause the crop circles? At first, people thought that some kids were making them as a joke, or that farmers were making them to attract tourists. (In fact, in 1991, two men said they made the circles themselves, but many scientists don’t believe them.), and they couldn’t flatten the wheat without breaking it. For several times, people reported seeing strange objects near the fields where crop circles later appeared. Many people believe that these crop circles are the messages sent by living things for outer space or the marks left by their spaceships. Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990, some scientists spent three weeks in the part of England where many circles have appeared. They had all the latest high-tech equipment (最新高科技设备). The equipment-worth 1.8 million dollars—got nothing. But one night, crop circles formed in the field behind them, which were quite different from the others. The scientists had neither seen nor heard anything. When Steven discovered the crop circles on his land in 1978, he said, “It was just like something that had landed in the field from the air and gone back up again. I don’t know what to make of these things.” Crop circles have appeared in England, Japan, the United States and Russia. Experts from all over the world have studied them, and they say what Steven said: we don’t know what to make of these things. 13．Which picture is probably the one formed in the field behind the scientists? A． B． C． D． 14．“Flattened wheat” means ________. A．harvested wheat B．growing wheat C．broken wheat D．lying wheat 15．Which of the following sentences is NOT true according to the passage? A．Crop circles are always discovered in the morning. B．The crop circles maybe form at night. C．Crop circles have appeared all over the world. D．The wheat in the circles can keep on growing. 16．The passage is mainly about something ________. A．that is discovered and copied by the farmer B．that is done by living things from outer space C．that cannot be solved but found all around the world D．that cannot be made clear or understood Passage5 In a factory in Germany, something unusual is happening. Every machine on the production line is under the watch of intelligent sensors (智能传感器). If a robot uses too much electricity, the intelligent program will slow it down to reduce energy waste. If an important part begins to wear out, workers will get a warning before it breaks down. With these digital tools, the factory has not only cut its electricity use by 20% but also increased its production to a record high, showing the great power of joining technology and sustainability (可持续性). This is more than just a factory story. Experts name it the “twin transition (转型)”. It connects digital transition and sustainability in a way that not only focuses on using digital tools or saving energy. Instead, it aims to use digital technologies to help protect our planet. What makes this transition special is that it turns the once-separate goals of technological progress and environmental protection into a united task that benefits both businesses and the earth. The idea is already being used in the “digital twin”, a virtual replica (虚拟副本) of a real machine in which robots can practice and repeat difficult tasks again and again without wasting any materials or risking harm to real parts. The technology records all effective actions and removes ineffective ones. After enough virtual tests, the robot can perform perfectly in the real world. It cuts down material waste and stops breakdowns, which would need expensive repairs under normal conditions. However, the twin transition is not a perfect solution by itself. Although digital tools help people complete tasks with less effort and better results, people may end up using them more often, leading to increased energy use in the long run, a problem known as the “rebound effect.” Another challenge is the “digital divide.” Both developed and poorer areas have tried the twin transition, but poorer areas are short of high-speed Internet and practical digital skills. As a result, they cannot get the same benefits from the transition as developed areas do. To solve these problems, experts suggest that good leadership and proper education are key. Companies need leaders with an understanding of both technology and the natural world. Schools should teach students how to use digital tools to solve environmental problems. In fact, there is no need for technological progress to clash with nature. With the right actions, the twin transition will guide us toward a more sustainable and intelligent future. 17．Why does the writer talk about the factory in Germany in Paragraph 1? A．To introduce a new idea. B．To prove a common view. C．To compare two situations. D．To advise on general matters. 18．According to the passage, what is a good example of the “twin transition”? A．Providing high-speed Internet to poor areas to close the digital divide. B．Training students to use digital tools to solve environmental problems. C．Using green energy to produce more electricity for industrial machines. D．Practicing tasks on a virtual copy of a machine to prevent material waste. 19．What does the underlined word “clash” in the last paragraph most probably mean? A．Mix. B．Trade. C．Fight. D．Connect. 20．Which of the following would be the best title for this passage? A．Joining Technology and Nature: A New Way B．Going Green: A Smarter Way with Digital Tools C．Transition and Sustainability: Goals of Companies D．Digital Twin: A Virtual Replica for Robot Practice Passage6 ②AI played an important part in this surgery. By studying lots of medical data (数据), AI helps doctors plan the surgery, predict problems that could happen, and find the ways to solve them. ③During the surgery, AI also tells the doctors the patient’s necessary information, like heart rate, blood pressure and oxygen levels. If anything of the patient goes wrong, it can warn doctors and suggest to change the plan. ④Another key role in this surgery was supercomputer technology. Remote surgeries need fast data transmission (传送), as even small delays (延迟) can be dangerous. Supercomputing can quickly deal with a lot of data, making sure that the surgery pictures are clear and the doctors’ orders are followed at once. ⑤The robot does an excellent job in this surgery. It has one arm and one hole, which makes the cut smaller, making less pain and speeding up the process for the patient to get better. It also increases the chances of a successful surgery and lowers the risk of accidents. ⑥This kind of surgery is a huge excitement, especially for people in remote areas. It means that patients don’t have to travel far for good medical care, saving time and being treated in time. ⑦And for places with fewer doctors, this kind of surgery also brings good news as doctors from bigger cities can help with surgeries and train local doctors. This kind of surgery is important for improving healthcare everywhere. 21．How does the writer lead into AI-powered remote surgery? A．By giving reasons. B．By telling a story. C．By listing numbers. D．By giving an example. 22．Which of the following questions is answered in Paragraph 4? A．Why does the surgery need the help of supercomputer? B．Where was the surgery performed? C．How’s the normal computer different from the supercomputer? D．When is the best time for the supercomputer to deal with the data? 23．What is the theme of the passage? A．Art. B．Culture. C．Travel. D．Technology. 24．Which of the following shows the structure of this passage? (①= Para. 1 ②= Para. 2 ③= Para. 3 ④= Para. 4 ⑤= Para. 5 ⑥= Para. 6 ⑦= Para. 7) A． B． C． D． Passage7 AI (Artificial Intelligence) and machine learning refer to the ability of machines to learn and act intelligently. It means they can make decisions, finish tasks, and even tell the possible future results based on what they learn from the data (数据). AI and machine learning already play a bigger role in everyday life than you might imagine. Health care, banking, video games, every search on the Internet you make…, all are driven by AI. AI is going to change almost every field of modern life. A famous scientist once said, “Success in creating AI would be the biggest event in human history.” And he added at once, “Unluckily, it might also be the last, unless we learn how to avoid the risks.” As we know, there are possible huge risks for society and human life, especially when you consider some countries are racing to develop AI-enabled autonomous weapons (人工智能自主武器). It is also going to change and take the place of many human jobs. The same worries also come from the public. According to the survey conducted by Centre for the Governance of AI, 91% of the people (tend to and totally) agree that “AI is a technology that requires careful management” in Europe. But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots, some people believe AI will make our working lives better. It will improve the work of humans, and new jobs will appear to take the place of the old ones. What’s more, machines become more intelligent and they are able to finish more human tasks. Things, which only belong to humans like creativity and critical (批判性的) thought will become even more valuable in the future. Like it or not, AI is here. Maybe changing ourselves and managing it well are the best way out. Just as Benjamin Franklin once said, “When you’ve finished changing, you’re finished.” 25．What’s the main idea of Paragraph 2? A．AI is widely used in daily life. B．People face risks of using AI. C．The management of AI is hard. D．AI has replaced human. 26．According to the chart (图表) and Paragraph 4, what percentage of people ________ disagree the careful management of AI? A．5% B．91% C．4% D．9% 27．What do you know from the underlined sentence? A．AI will become less valuable than people expected. B．AI will become more intelligent than humans. C．Humans have some special abilities that AI doesn’t have. D．Humans will be replaced by AI in the future. 28．Which of the following shows the structure of this text? (①＝Paragraph 1, ②＝Paragraph 2…) A． B． C． D． Passage8 ②Police can use software (软件) to age photos of missing people, but it seems to work best in adults, as age-related changes of adult faces are much easier to predict and to make. ③Unlike adults, the faces of children change greatly as time goes by, and matching photos of found children to old images (画像) in a database (数据库) of missing children is difficult. “Even with a recent face image of a child, it is quite hard for a human to recognize (辨认), visually, who the child is from a large data set of child face images,” says Debayan Deb at Michigan State University. ④Now Deb and his teammates have created an algorithm (算法) to work out the problem. They created a face-recognition algorithm on data sets, which have images of nearly 1,000 children between 2 and 18 years old. And they took photos of them at least four times over a period of six years. ⑤AI learned to match recent photographs of children with images taken 2.5 years earlier. The correct matching rate can be 80 percent. With one year between the two photographs, it was 90 percent correct at recognizing faces. This dropped to 73 percent after three years. The new AI might help to improve accuracy (准确性) of this kind of software, too. ⑥Deb’s next goal (目标) is to make the age gap wider. His team also hopes to develop an app to fight against the sale of children. 29．What does the underlined word “them” in paragraph 1 refer to? A．School children. B．The missing children. C．The children’s faces. D．The last-known photos. 30．Why does Deb’s team do the research according to paragraph 4? A．To make it easier to match missing children with old photos. B．To build a database to find the missing children. C．To help the police change and improve their software. D．To tell the difference between adults and children. 31．What can we infer from the passage? A．Deb’s team has already made the age gap wider. B．AI can help to improve accuracy of matching rate. C．Deb and his team will still work hard to develop a new app. D．It is hard to recognize a found child even with a recent image. 32．Which of the following best shows the structure of this passage? A． B． C． D． 2 原创精品资源学科网独家享有版权，侵权必究！ 1 / 11 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $ Unit 3 Technology and Inventions 单元阅读精练 模块 语篇 题型 体裁 词数 内容简介 时文 阅读 Passage1 阅读理解 说明文 213 以纸、印刷术和互联网为例，说明伟大发明如何改变知识传播方式，并指出许多发明只是解决了普通人的真实问题。 Passage2 阅读理解 说明文 207 介绍无人机在农业、城市配送与灾后救援中的用途及其带来的问题，说明谨慎使用能让生活更安全便利。 实战 演练 Passage1 阅读理解 新闻报道 278 报道主播董宇辉因直播文案争议反而更受欢迎，分析其走红原因与给年轻主播的建议。 Passage2 阅读理解 记叙文 278 讲述航天员王杰从内蒙古农家少年到神舟二十号乘组的成长历程。 Passage3 阅读理解 说明文 305 介绍2025年央视春晚“YangBOT”机器人扭秧歌节目，说明科技与传统文化结合的魅力。 Passage4 阅读理解 说明文 423 介绍麦田怪圈的发现过程、形态特征，以及科学界至今未解的研究现状。 Passage5 阅读理解 说明文 404 介绍“双重转型”这一数字技术与可持续发展相结合的新理念及其应用、优势与挑战。 Passage6 阅读理解 说明文 237 以跨洲远程手术为例，说明AI、超级计算机与手术机器人在远程医疗中的作用。 Passage7 阅读理解 说明文 315 介绍AI在各领域的广泛应用，同时讨论其风险与人类的应对之道。 Passage8 阅读理解 说明文 228 讲述Deb团队用AI比对失踪儿童旧照，帮助失散家庭团聚的研究。 Passage1 Inventions That Changed Our Days English 中文翻译 Every day we use objects that once seemed impossible. Paper, printing, electricity and the Internet all began as someone's idea, and each of them changed the way people live. 每天我们都在使用曾经看似不可能的东西。纸、印刷术、电和互联网都始于某个人的想法，而它们每一个都改变了人们的生活方式。 Take paper as an example. Before paper was invented, people in China wrote on bamboo pieces or silk. Bamboo was heavy and silk was expensive. When paper appeared, knowledge became easier to keep and carry, and more people could afford to learn to read. 以纸为例。在纸被发明之前，中国人把字写在竹片或丝绸上。竹片很重，丝绸很贵。纸出现后，知识变得更容易保存和携带，也有更多人负担得起读书识字。 Printing went one step further. With printing, a book no longer had to be copied by hand, so ideas could travel faster than ever. Centuries later, the Internet did something similar: it made information reach almost every corner of the world in seconds. 印刷术又向前迈进了一步。有了印刷术，书不必再靠手抄，思想得以以前所未有的速度传播。几个世纪后，互联网做了类似的事：它让信息在几秒钟内到达世界的几乎每一个角落。 Not every invention is famous, however. A better water pump, a stronger bicycle light or a cheaper way to store food can improve daily life just as much. Great inventions do not always look great at first; most of them simply solve a real problem for ordinary people. 然而，并非每一项发明都很有名。一个更好的水泵、一盏更亮的自行车灯，或一种更便宜的储存食物的方法，同样能改善日常生活。伟大的发明起初并不总是显得伟大；它们中的大多数只是为普通人解决了一个真实的问题。 Inventions also change as people use them. The first bicycles had no pedals, and the first phones could only make calls. Users kept finding new needs, and inventors kept answering them. In this way, a simple idea can grow into something that nobody could have imagined at the start. 发明也会随着人们的使用而改变。最早的自行车没有脚踏板，最早的手机只能打电话。使用者不断发现新的需求，发明者不断作出回应。就这样，一个简单的想法可以成长为一开始没有人能想象的东西。 【长难句分析】 1. 原句：Before paper was invented, people in China wrote on bamboo pieces or silk. 翻译：在纸被发明之前，中国人把字写在竹片或丝绸上。 重点：Before 引导时间状语从句，用一般过去时；was invented 为被动语态。 2. 原句：With printing, a book no longer had to be copied by hand, so ideas could travel faster than ever. 翻译：有了印刷术，书不必再靠手抄，思想得以以前所未有的速度传播。 重点：no longer 意为“不再”；have to be done 结构；so 引导结果状语从句；than ever 与比较级连用。 3. 原句：Great inventions do not always look great at first; most of them simply solve a real problem for ordinary people. 翻译：伟大的发明起初并不总是显得伟大；它们中的大多数只是为普通人解决了一个真实的问题。 重点：not always 表示部分否定；分号连接两个并列分句；solve a problem for sb. 意为“为某人解决问题”。 【重难词汇梳理】 1. invent /ɪnˈvent/ v. 发明 6. afford /əˈfɔːd/ v. 负担得起 2. invention /ɪnˈvenʃn/ n. 发明 7. century /ˈsentʃəri/ n. 世纪 3. bamboo /ˌbæmˈbuː/ n. 竹子 8. pump /pʌmp/ n. 泵 4. silk /sɪlk/ n. 丝绸 9. store /stɔː(r)/ v. 储存 5. knowledge /ˈnɒlɪdʒ/ n. 知识 10. solve /sɒlv/ v. 解决 Passage2 Drones: Helpers in the Sky English 中文翻译 A drone is a small aircraft without a pilot on board. At first, drones were mostly used by armies. Today, however, they have become useful helpers in many parts of our lives. 无人机是一种机上没有飞行员的小型飞行器。起初，无人机多用于军队。然而今天，它们已经成为我们生活许多方面的有用帮手。 In the countryside, farmers use drones to spray water or medicine over their fields. A drone can cover a large area in a short time, which saves both time and water. In cities, drones deliver medicine to hospitals and help firefighters find people in thick smoke. 在乡村，农民用无人机给田地喷洒水或药液。一架无人机能在短时间内覆盖大片区域，这既省时又省水。在城市，无人机为医院运送药品，还能帮助消防员在浓烟中找到人。 Drones are also helpful after disasters. When an earthquake breaks roads, a drone can fly over the damaged area and send back pictures. Rescue teams can then decide where to go first, without putting themselves in danger. 无人机在灾后也很有用。当地震破坏了道路，无人机可以飞越受损区域并传回图像。救援队随后可以决定先去哪里，而不用让自己身处危险之中。 Still, drones bring problems. They may hit birds, fall on people, or film others without permission. That is why many countries have made rules about where and when drones can fly. Used carefully, these small machines can make our world safer and more convenient. 不过，无人机也带来问题。它们可能撞到鸟、掉落到人身上，或未经允许拍摄他人。正因如此，许多国家制定了关于无人机飞行地点和时间的规则。只要谨慎使用，这些小型机器可以让我们的世界更安全、更便利。 For young people, drones are more than toys. Learning to fly one safely teaches patience, careful planning and respect for rules. Some students even build their own drones and test them in competitions. Who knows? The next great use of drones may come from a classroom like yours. 对年轻人来说，无人机不只是玩具。学会安全地操控无人机，能培养耐心、周密计划和对规则的尊重。有些学生甚至自己制作无人机，并在比赛中测试。谁知道呢？无人机的下一个伟大用途，也许就来自像你这样的课堂。 【长难句分析】 1. 原句：A drone can cover a large area in a short time, which saves both time and water. 翻译：一架无人机能在短时间内覆盖大片区域，这既省时又省水。 重点：which 引导非限制性定语从句，指代前面整句话；both...and... 连接并列成分。 2. 原句：When an earthquake breaks roads, a drone can fly over the damaged area and send back pictures. 翻译：当地震破坏了道路，无人机可以飞越受损区域并传回图像。 重点：When 引导时间状语从句；send back 意为“传回、送回”；damaged 为过去分词作定语。 3. 原句：That is why many countries have made rules about where and when drones can fly. 翻译：正因如此，许多国家制定了关于无人机飞行地点和时间的规则。 重点：That is why... 意为“这就是……的原因”；about 后接 where/when 引导的宾语从句。 【重难词汇梳理】 1. drone /drəʊn/ n. 无人机 6. firefighter /ˈfaɪəfaɪtə(r)/ n. 消防员 2. aircraft /ˈeəkrɑːft/ n. 飞行器，飞机 7. disaster /dɪˈzɑːstə(r)/ n. 灾难 3. army /ˈɑːmi/ n. 军队 8. rescue /ˈreskjuː/ n. & v. 营救 4. spray /spreɪ/ v. 喷洒 9. permission /pəˈmɪʃn/ n. 允许 5. deliver /dɪˈlɪvə(r)/ v. 递送 10. convenient /kənˈviːniənt/ adj. 便利的 Passage1 Battles over sales Livestreamer Dong Yuhui wins hearts over a controversy “顶流”主播董宇辉的上升之路 Dong Yuhui, a 30-year-old livestreaming (直播) host for East Buy (东方甄选), found himself in an online controversy (争议) that began on Dec 5. East Buy, a subsidiary (子公司) of New Oriental Education (新东方教育科技集团), said that many of the things Dong said in his livestreams were written by the East Buy team, not by himself. The then-CEO, Sun Dongxu, criticized Dong and the team, which made Dong’s fans upset. Surprisingly, this controversy made Dong even more popular. In just one week, his Douyin followers (关注者) increased by over 3 million, while East Buy lost more than 2 million followers. Sun was no longer the CEO, and Dong became vice president (副总裁) of New Oriental’s cultural and tourism business. Despite his rising fame, Dong remains humble. “I am not good-looking or tall; I don’t know why I have so many supporters,” he said. However, Xu Hanze, an associate professor (副教授) at Nanjing University of Aeronautics and Astronautics (南京航空航天大学), believes that Dong got more attention because of his talent and intelligence, thanks to his habit of reading extensively. In the age of consumerism (消费主义), Dong does not trick consumers into buying unnecessary products, but encourages them to be rational (理性的) when shopping online. He also puts more effort into educational activities and events to help farmers. He believes that people should not wish to be the next Dong Yuhui. “I want to tell other young livestreamers that they do not need to be me, as each story is moving in its own way.” He went on to say that people are not products made on manufacturing lines, and that diversity (不同) is what makes people special.          China Daily 1．What raised the controversy?

During the CCTV Spring Festival Gala, a very popular TV show, people saw a dance called “Yang BOT”. Famous movie director Zhang Yimou made this show. This special show mixed an old Chinese dance called “yangko” with new robot technology. Yangko is a joyful and traditional dance from the north of China. People often dance it during holidays. In the show, humanoid robots (robots shaped like humans) who wear bright and colorful clothes danced yangko. The robots waved colorful handkerchiefs (手帕) very fast and made interesting shapes together. These robots were developed by Unitree (宇树科技), a Chinese robotics company. This was not Unitree’s first success. Back in 2021, Unitree made robot cows named “Ben Ben”. These robot cows danced behind the famous singer Andy Lau. They moved in a funny way but the performance weren’t very smooth then. But this time, the Yang BOT robots were much better! They danced through AI and used laser navigation (激光导航). This helped them move safely and quickly, even on a stage that wasn’t flat. It was a big step forward in robot technology. Director Zhang Yimou said, “This dance isn’t just fun. It shows how new technology can help old traditions become new and exciting again.” Thanks to these improvement, the robots won the hearts of millions. On social media, topics like “Robot Yangko” became hot quickly. Young people thought it was “cool”. Older people enjoyed the humor and happiness it brought to them. The Yang BOT show is a great mix of China’s technological progress and cultural pride. One fan said, “It’s like watching the future and the past dance together!” Many people, especially Chinese people living in other countries, wrote messages on CCTV’s website.

Some of his wheat was lying on the ground. The flattened wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat. Three years later, a farmer who lived nearby discovered almost the same circles in one of his fields. These circles were larger—nearly 15 meters across. In the Same year, another English farmer discovered three circles of flattened wheat on his land—one large circle between two small circles. During the following years, farmers in England found circles in their fields more and more often. The circles are called “crop circles” because they usually appear in fields of wheat or corn. The wheat in the circles lies on the ground but is never broken; it keeps on growing, and the farmers can later harvest it. Farmers always discover the crop circles in the morning, so the circles probably form at night. They appear only in the months from May to September. What cause the crop circles? At first, people thought that some kids were making them as a joke, or that farmers were making them to attract tourists. (In fact, in 1991, two men said they made the circles themselves, but many scientists don’t believe them.), and they couldn’t flatten the wheat without breaking it. For several times, people reported seeing strange objects near the fields where crop circles later appeared. Many people believe that these crop circles are the messages sent by living things for outer space or the marks left by their spaceships. Scientists who have studied the crop circles try to find out what causes them. In the summer of 1990, some scientists spent three weeks in the part of England where many circles have appeared. They had all the latest high-tech equipment (最新高科技设备). The equipment-worth 1.8 million dollars—got nothing. But one night, crop circles formed in the field behind them, which were quite different from the others. The scientists had neither seen nor heard anything. When Steven discovered the crop circles on his land in 1978, he said, “It was just like something that had landed in the field from the air and gone back up again. I don’t know what to make of these things.” Crop circles have appeared in England, Japan, the United States and Russia. Experts from all over the world have studied them, and they say what Steven said: we don’t know what to make of these things. 13．Which picture is probably the one formed in the field behind the scientists? A． B． C． D． 14．“Flattened wheat” means ________. A．harvested wheat B．growing wheat C．broken wheat D．lying wheat 15．Which of the following sentences is NOT true according to the passage? A．Crop circles are always discovered in the morning. B．The crop circles maybe form at night. C．Crop circles have appeared all over the world. D．The wheat in the circles can keep on growing. 16．The passage is mainly about something ________. A．that is discovered and copied by the farmer B．that is done by living things from outer space C．that cannot be solved but found all around the world D．that cannot be made clear or understood 【答案】13．A 14．D 15．C 16．D 【导语】本文主要介绍了麦田怪圈现象。 【详解】13．推理判断题。根据“Some of his wheat was lying on the ground. The flattened wheat formed a circle about six meters across. Around this circle were four smaller circles of flattened wheat.”和“ Three years later, a farmer who lived nearby discovered almost the same circles in one of his fields.”可知传统的麦田怪圈都是圆圈的形状。根据倒数第三段“But one night, crop circles formed in the field behind them, which were quite different from the others. The scientists had neither seen nor heard anything.”可知这次在科学家背后形成的麦田怪圈和之前的都不一样。结合四个选项，只有A选项中出现了不一样的形状。故选A。 14．词义猜测题。根据“Some of his wheat was lying on the ground.”可知这里flattered wheat指的是上文提到的倒在地上的麦子。故选D。 15．细节理解题。根据“Crop circles have appeared in England, Japan, the United States and Russia.”可知并非全世界都出现了麦田怪圈。故选C。 16．主旨大意题。通读全文可知本文主要介绍了麦田怪圈这一现象，这一现象至今没有科学的解释，故选D。 Passage5 In a factory in Germany, something unusual is happening. Every machine on the production line is under the watch of intelligent sensors (智能传感器). If a robot uses too much electricity, the intelligent program will slow it down to reduce energy waste. If an important part begins to wear out, workers will get a warning before it breaks down. With these digital tools, the factory has not only cut its electricity use by 20% but also increased its production to a record high, showing the great power of joining technology and sustainability (可持续性). This is more than just a factory story. Experts name it the “twin transition (转型)”. It connects digital transition and sustainability in a way that not only focuses on using digital tools or saving energy. Instead, it aims to use digital technologies to help protect our planet. What makes this transition special is that it turns the once-separate goals of technological progress and environmental protection into a united task that benefits both businesses and the earth. The idea is already being used in the “digital twin”, a virtual replica (虚拟副本) of a real machine in which robots can practice and repeat difficult tasks again and again without wasting any materials or risking harm to real parts. The technology records all effective actions and removes ineffective ones. After enough virtual tests, the robot can perform perfectly in the real world. It cuts down material waste and stops breakdowns, which would need expensive repairs under normal conditions. However, the twin transition is not a perfect solution by itself. Although digital tools help people complete tasks with less effort and better results, people may end up using them more often, leading to increased energy use in the long run, a problem known as the “rebound effect.” Another challenge is the “digital divide.” Both developed and poorer areas have tried the twin transition, but poorer areas are short of high-speed Internet and practical digital skills. As a result, they cannot get the same benefits from the transition as developed areas do. To solve these problems, experts suggest that good leadership and proper education are key. Companies need leaders with an understanding of both technology and the natural world. Schools should teach students how to use digital tools to solve environmental problems. In fact, there is no need for technological progress to clash with nature. With the right actions, the twin transition will guide us toward a more sustainable and intelligent future. 17．Why does the writer talk about the factory in Germany in Paragraph 1? A．To introduce a new idea. B．To prove a common view. C．To compare two situations. D．To advise on general matters. 18．According to the passage, what is a good example of the “twin transition”? A．Providing high-speed Internet to poor areas to close the digital divide. B．Training students to use digital tools to solve environmental problems. C．Using green energy to produce more electricity for industrial machines. D．Practicing tasks on a virtual copy of a machine to prevent material waste. 19．What does the underlined word “clash” in the last paragraph most probably mean? A．Mix. B．Trade. C．Fight. D．Connect. 20．Which of the following would be the best title for this passage? A．Joining Technology and Nature: A New Way B．Going Green: A Smarter Way with Digital Tools C．Transition and Sustainability: Goals of Companies D．Digital Twin: A Virtual Replica for Robot Practice 【答案】17．A 18．D 19．C 20．B 【导语】本文是一篇说明文，介绍了“双重转型”这一将数字技术与可持续发展相结合的新理念，通过实例说明了其应用、优势与面临的挑战。 【详解】17．文章第一段描述了德国工厂使用智能传感器的案例，第二段紧接着指出“This is more than just a factory story. Experts name it the ‘twin transition’”，说明提及工厂案例是为了引出“双重转型”这一新理念。 18．第三段提到“The idea is already being used in the ‘digital twin’... virtual replica... without wasting any materials”，说明在机器的虚拟副本上练习任务、减少材料浪费，是“双重转型”理念的典型应用，对应选项D。 19．最后一段提到“With the right actions... guide us toward a more sustainable... future”，说明技术进步与自然可以和谐共存。语境中“no need to... clash”意为无需冲突，clash意为“冲突、斗争”，与Fight同义。 20．本文核心围绕“双转型”展开，核心内容是借助数字工具实现可持续绿色发展。选项B“走向绿色：利用数字工具的智能方式”符号题意。 ①Can you imagine a doctor performing a surgery (手术) on a patient thousands of kilometers away? A recent surgery was done by doctors in Chengdu. Using a robotic technology, the doctors saved a patient in Lhasa (拉萨). With the development of AI-powered remote surgery (人工智能辅助远程手术), modern healthcare has changed in a big way. Passage6 ②AI played an important part in this surgery. By studying lots of medical data (数据), AI helps doctors plan the surgery, predict problems that could happen, and find the ways to solve them. ③During the surgery, AI also tells the doctors the patient’s necessary information, like heart rate, blood pressure and oxygen levels. If anything of the patient goes wrong, it can warn doctors and suggest to change the plan. ④Another key role in this surgery was supercomputer technology. Remote surgeries need fast data transmission (传送), as even small delays (延迟) can be dangerous. Supercomputing can quickly deal with a lot of data, making sure that the surgery pictures are clear and the doctors’ orders are followed at once. ⑤The robot does an excellent job in this surgery. It has one arm and one hole, which makes the cut smaller, making less pain and speeding up the process for the patient to get better. It also increases the chances of a successful surgery and lowers the risk of accidents. ⑥This kind of surgery is a huge excitement, especially for people in remote areas. It means that patients don’t have to travel far for good medical care, saving time and being treated in time. ⑦And for places with fewer doctors, this kind of surgery also brings good news as doctors from bigger cities can help with surgeries and train local doctors. This kind of surgery is important for improving healthcare everywhere. 21．How does the writer lead into AI-powered remote surgery? A．By giving reasons. B．By telling a story. C．By listing numbers. D．By giving an example. 22．Which of the following questions is answered in Paragraph 4? A．Why does the surgery need the help of supercomputer? B．Where was the surgery performed? C．How’s the normal computer different from the supercomputer? D．When is the best time for the supercomputer to deal with the data? 23．What is the theme of the passage? A．Art. B．Culture. C．Travel. D．Technology. 24．Which of the following shows the structure of this passage? (①= Para. 1 ②= Para. 2 ③= Para. 3 ④= Para. 4 ⑤= Para. 5 ⑥= Para. 6 ⑦= Para. 7) A． B． C． D． 【答案】21．D 22．A 23．D 24．D 【导语】本文介绍了人工智能辅助远程手术技术，通过具体案例说明AI、超级计算机和手术机器人在远程医疗中的重要作用，并讨论了该技术对偏远地区医疗服务的积极影响。 【详解】21．推理判断题。根据“Can you imagine a doctor performing a surgery (手术) on a patient thousands of kilometers away? A recent surgery was done by doctors in Chengdu. ”可知，作者通过讲述一个成都医生为拉萨病人实施远程手术的真实案例来引入话题。故选D。 22．推理判断题。根据“Remote surgeries need fast data transmission (传送), as even small delays (延迟) can be dangerous. Supercomputing can quickly deal with a lot of data,”可知，第四段解释了远程手术需要超级计算机的原因（快速处理数据、避免延迟风险），回答了“为何需要超级计算机辅助”的问题。故选A。 23．主旨大意题。全文围绕AI辅助远程手术这一技术展开，分别介绍了AI的作用、超级计算机技术、手术机器人及其对医疗资源不均衡地区的意义，因此主题是技术。故选D。 24．篇章结构题。文章第一段引入案例；第二三段介绍AI作用；第四段介绍超级计算机技术；第五段介绍了手术机器人；第六七段是总结意义。故选D。 Passage7 AI (Artificial Intelligence) and machine learning refer to the ability of machines to learn and act intelligently. It means they can make decisions, finish tasks, and even tell the possible future results based on what they learn from the data (数据). AI and machine learning already play a bigger role in everyday life than you might imagine. Health care, banking, video games, every search on the Internet you make…, all are driven by AI. AI is going to change almost every field of modern life. A famous scientist once said, “Success in creating AI would be the biggest event in human history.” And he added at once, “Unluckily, it might also be the last, unless we learn how to avoid the risks.” As we know, there are possible huge risks for society and human life, especially when you consider some countries are racing to develop AI-enabled autonomous weapons (人工智能自主武器). It is also going to change and take the place of many human jobs. The same worries also come from the public. According to the survey conducted by Centre for the Governance of AI, 91% of the people (tend to and totally) agree that “AI is a technology that requires careful management” in Europe. But rather than agreeing with an idea of a helpless future where all human jobs are given over to robots, some people believe AI will make our working lives better. It will improve the work of humans, and new jobs will appear to take the place of the old ones. What’s more, machines become more intelligent and they are able to finish more human tasks. Things, which only belong to humans like creativity and critical (批判性的) thought will become even more valuable in the future. Like it or not, AI is here. Maybe changing ourselves and managing it well are the best way out. Just as Benjamin Franklin once said, “When you’ve finished changing, you’re finished.” 25．What’s the main idea of Paragraph 2? A．AI is widely used in daily life. B．People face risks of using AI. C．The management of AI is hard. D．AI has replaced human. 26．According to the chart (图表) and Paragraph 4, what percentage of people ________ disagree the careful management of AI? A．5% B．91% C．4% D．9% 27．What do you know from the underlined sentence? A．AI will become less valuable than people expected. B．AI will become more intelligent than humans.

Now AI (人工智能) can make it easier to match any found children to those old photos. Passage8 ②Police can use software (软件) to age photos of missing people, but it seems to work best in adults, as age-related changes of adult faces are much easier to predict and to make. ③Unlike adults, the faces of children change greatly as time goes by, and matching photos of found children to old images (画像) in a database (数据库) of missing children is difficult. “Even with a recent face image of a child, it is quite hard for a human to recognize (辨认), visually, who the child is from a large data set of child face images,” says Debayan Deb at Michigan State University. ④Now Deb and his teammates have created an algorithm (算法) to work out the problem. They created a face-recognition algorithm on data sets, which have images of nearly 1,000 children between 2 and 18 years old. And they took photos of them at least four times over a period of six years. ⑤AI learned to match recent photographs of children with images taken 2.5 years earlier. The correct matching rate can be 80 percent. With one year between the two photographs, it was 90 percent correct at recognizing faces. This dropped to 73 percent after three years. The new AI might help to improve accuracy (准确性) of this kind of software, too. ⑥Deb’s next goal (目标) is to make the age gap wider. His team also hopes to develop an app to fight against the sale of children. 29．What does the underlined word “them” in paragraph 1 refer to? A．School children. B．The missing children. C．The children’s faces. D．The last-known photos. 30．Why does Deb’s team do the research according to paragraph 4? A．To make it easier to match missing children with old photos. B．To build a database to find the missing children. C．To help the police change and improve their software. D．To tell the difference between adults and children. 31．What can we infer from the passage? A．Deb’s team has already made the age gap wider. B．AI can help to improve accuracy of matching rate. C．Deb and his team will still work hard to develop a new app. D．It is hard to recognize a found child even with a recent image. 32．Which of the following best shows the structure of this passage? A． B． C． D． 【答案】29．B 30．A 31．C 32．D 【导语】本文主要讲述了Deb和他的团队利用现代科技——人工智能来帮助我们识别长大后的失踪儿童，主要使用人工智能来匹配失踪孩子和他们的旧照片， 【详解】29．词义猜测题。根据“As missing children get older, they become quite different from the faces in their last-known photographs, which makes finding them really difficult”可知，此处指寻找失踪的孩子们，故选B。 30．细节理解题。根据“Unlike adults, the faces of children change greatly as time goes by, and matching photos of found children to old images (画像) in a database (数据库) of missing children is difficult.”及“Now Deb and his teammates have created an algorithm to work out the problem”可知，是为了解决“随着时间的推移，儿童的脸会发生很大的变化，因此很难将找到的儿童的照片与失踪儿童数据库中的旧照片进行匹配”这个问题，也就是说目的是为了让失踪儿童和旧照片更容易匹配，故选A。 31．推理判断题。根据“His team also hopes to develop an app to fight against the sale of children.”可知，他的团队还希望开发一款应用来打击贩卖儿童行为，故选C。 32．篇章结构题。通读全文可知，第一段是介绍失踪儿童随着年龄增长，很难与旧照片匹配，而人工智能能让这个变得更容易，以此引出本文主题；第二段和第三段是介绍警察用软件匹配失踪人口所遇到的问题；第四段和第五段提出了解决问题的方法；最后一段是表达了对未来的设想，故选D。 2 原创精品资源学科网独家享有版权，侵权必究！ 1 / 11 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
