Unit 3 Our digital lives 单元话题阅读理解 Unit 3 Our digital lives单元话题：科学技术 本资料共10篇专题训练，从上到下依次按照难度分为基础语篇巩固练和重难语篇提升练 基础语篇巩固练 “Could you please plan a four-day trip for a family to Jilin Province in northeast China? We’re a family of four from Beijing,” Wang Qian, a mother of two, asked the AI platform (平台) DeepSeek before this year’s National Day holiday. Wang is part of a growing number of Chinese tourists using AI to enhance their travel experiences. In China, AI technology is developing very fast. Major tourism platforms have integrated (融合) AI technology, allowing users to ask questions about their travel plans. Then AI can provide advice that suits them within minutes. Liang Jianzhang, chairman of Trip.com Group, said, “AI can answer 80 percent of the questions, reducing (减少) users’ trip-planning time from about 9 hours to 6.6 hours.” Not only tourism platforms, but also some provinces and cities are using AI to develop tourism. In Guizhou Province, a digital (数字的) human named Huang Xiaoxi, dressed in traditional local clothes, provides tourists with many kinds of service, like giving information, booking tickets, and even writing travel notes. Wearable smart guide devices (设备) have also become more popular in China, especially in museums. These devices offer users a private AI tour guide at a much lower price than human guides. AI is changing travel experiences in China in many ways. In the future, it will play an even more important role in Chinese tourism. 1．What does the underlined word “enhance” most probably mean? A．Record. B．Improve. C．Believe. D．Share. 2．What does Liang Jianzhang think of AI? A．It helps save time. B．It’s developing fast. C．It helps save money. D．It’s becoming more popular. 3．Huang Xiaoxi can do the following things except (除了) ________. A．booking tickets B．giving information C．writing travel notes D．making traditional local clothes 4．Where is the text taken from? A．A science magazine. B．An English novel. C．A travel diary. D．A history textbook. Lots of people go travelling during holidays. As travellers look for more personalized (个人特制的) experiences, many choose AI to be their online tour guides. During the May Day holiday, Wu Hongbo, a visitor from Dalian, travelled to Shanxi. It was his first visit to Shanxi. Wu didn’t want to join a tour group because he would have to spend a lot of money and he couldn’t explore freely. There were so many places of interest in Shanxi and he was not familiar with the travel routes (路线), so he turned to AI for help. Wu used AI to plan a fantastic tour of Shanxi. He input the places he wanted to visit, his travel dates, budget and personal interests into an AI app. Soon, he got a personalized week-long travel plan. It showed him the ways to get around, places to visit, and hotels to stay in. Wu is interested in ancient buildings and tasty food, so the AI app also listed several not-so-famous but culturally rich places and delicious dishes. “This AI-planned tour truly gave me great surprises,” Wu said. “The places and routes perfectly matched (与……一致) my taste, helping me understand Shanxi better.” Specialists believe 2025 will be the breakout year for AI tour guides. They think AI can meet tourists’ needs for personalized travel. During a personalized trip, AI can serve tourists in real time. Through modern technologies, an AI tour guide can act like a personal guide, explaining the historical stories and cultural meanings behind the tourist areas. In the future, AI tour guides will help human (人类的) guides and together they can bring a more personalized experience to make travel more exciting. 1．Why didn’t Wu travel with a tour group?

Do you want to know what these letters mean? These people describe themselves in terms of the personality types classified (分类) by the Myers-Briggs Type Indicator (MBTI). The test was developed by Isabel Myers and her mother Katharine Briggs according to their work with Carl Jung’s ideas about personality types. The MBTI is a self-report test developed to help people know about their own personality type, strengths, likes and dislikes. It is not used to test your mental (精神的) health. There are no right or wrong answers. No one personality type is the best or the worst. In recent years, the MBTI has been used in more and more areas. ▲ People take the test and it can help them to learn about what the best jobs are for each MBTI type. For example, ESTPs can easily go into marketing (营销), while ISTPs should become engineers. However, we should know that it is only a guide, and it cannot decide our dream jobs. The MBTI personality test may show us something we don’t know about ourselves. But we should not take its result too seriously. Who we are is shaped by our thoughts, values and daily behaviours. The result of the test can’t define (定义) who we are. 1．How does the writer start this passage? A．By asking questions. B．By giving examples. C．By telling stories.

Although it might sound a little far from you, living in a “smart” city like this could happen sooner than you think. Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a “telepresence system” (远程呈现系统)—allowing users to control the heating and locks, take part in video meetings, and receive education, healthcare and government services. Around the city, escalators (自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system. The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business. About 75% of the world’s population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. “Making cities smarter is one way out, and I think this will in turn make cities greener,” said Dan Hill, head of a research company. 1．According to the text, living in a “smart” city _______. A．is not a green way B．will be far from you C．is completely impossible D．will soon become true 2．What is Paragraph 2 mainly about? A．A meeting in Songdo. B．A city of the future.

A．solve the cities’ coming problems B．develop his own company C．control the world’s population D．drive people out of cities 5．Which of the following might be the best title for the text? A．Government Services B．Famous Companies C．Future Education D．Smart Cities A blogger (博主) from Sichuan shared an AI-made cartoon short film of “Journey to the West” on the Internet. The film surprised many people with its amazing visual effects (视觉效果) and created new ways to show classic stories. AI gives breathtaking visual effects and emotional experiences. The blogger, Mr. Feng, has 15 years of art experience. He said that a video, which would take at least six months to make without AI, was done in a week with AI’s help. He also talked about how to make videos with AI. Using the first part of “Journey to the West” as an example, he talked about how to decide how many pictures and storyboards are needed. He said he used ChatGPT to analyze (分析) the original text, plan the storyboards, draw with AI painting software, and then turned the pictures into a video. These processes usually create a lot of early versions (版本). “Right now, it’s hard for AI to fully understand what I mean, so the results are kind of random (随意的). Every time, I use AI to form a lot of materials to find the right one for the next step,” Mr. Feng said. When it comes to adding exciting fight scenes to the “Journey to the West” TV series and other works, Feng pointed out that there are still many limitations in AI-made videos, making it hard to do such scenes. 1．Why did the AI-made film surprise many people according to the text? A．It was created by a blogger from Sichuan. B．It showed a story with amazing visuals. C．It was shared on the Internet. D．It was the first AI-made film. 2．How long will it take AI to make a film which takes people a year to make? A．At most a week. B．At least six months. C．About two weeks. D．About one month. 3．Which question does Paragraph 4 answer? A．Who often uses AI to create artwork? B．What are the steps to create videos with AI? C．How many pictures are needed for a video? D．What is ChatGPT’s role in video creation? 4．What’s the meaning of the underlined word “limitations” in the last paragraph? A．goals B．abilities C．rules D．shortcomings 5．What’s Mr. Feng’s opinion about AI’s role in making films? A．He thinks it is perfect and has no weaknesses. B．He believes it still faces challenges in creating videos. C．He thinks it can easily overcome all challenges in film making. D．He doesn’t care about its development in film making. 重难语篇提升练 Getting a dream job has never been easy, but at least in the past you knew that the person you had to move was a human being. However, recently, more bosses are putting the work of finding the most acceptable worker on the inhuman shoulders. AI systems can read through thousands of resumes (简历) much faster than a person or even a group of people. What’s more, AI programs have been invented to run video interviews, too. While those who support such systems believe that this super useful hiring (雇佣) method is the future, others fear that the systems have serious problems. Because AI systems use unfair information to learn how to choose people, the hiring process (过程) may actually be more unfair when AI is used. A recent example of this was Amazon’s AI-hiring system, which paid no attention to women because most technical workers were men. Naturally, people who look for jobs are trying anything they can to satisfy the AI’s selection (选择) standards. Now, in South Korea a number of the top companies use AI for hiring. In order to get jobs, people attend special schools to learn how to pass their AI interviews. Of course, many of the skills taught in special schools are only educated (有根据的) guesses. Without knowing exactly what kind of person AI system looks for, knowing what to do to please it is very difficult, However, there are still some things you can try. For example, try to use special words in your interview answers because AI often searches information for special key words. Another tip is to make your resumes simple. That way, the AI can search it more easily. It seems our success could depend too much on the magical decision of a machine mind. It sounds unfair, and it may be. In the end, the power to either change the system itself or at least make it work for you is in your hands as long as you make up your mind. 根据语篇内容，按要求回答问题。 1．What does the underlined phrase “the inhuman shoulders” refer to (指的是)? A．AI systems. B．Bosses. C．Workmates. 2．What does the writer think of Amazon’s AI-hiring system? A．It knows about women. B．It’s not fair to women. C．It prefers to choose women. 3．What do people do to satisfy the AI’s selection standards? A．They learn how to pass their AI interview. B．They try to learn how to use computers. C．They write letters to some AI companies. 4．What does the underlined word “please” in Paragraph 4 mean? A．请便 B．选择 C．(使)满意 5．What’s the best title for the passage? A．Making up your mind B．Hired by a machine mind C．Amazon’s AI-hiring system ①In May 2025, Google shared a piece of news about a new AI model called SignGemma. It is made to understand American Sign Language (ASL) and turn it into English words on a screen. It can help deaf people talk with hearing people more quickly and more easily. ②SignGemma uses a phone camera to catch hand shapes, face moves, and body movements. In less than 200 milliseconds, it writes or speaks the meaning. Because the model works on the device, it does not need the cloud (云盘). That means faster answers, lower data cost, and safer personal information for users. ③To train SignGemma how to understand sign language, Google let it “watch” 10, 000 hours of sign language videos. Each video shows hands, face, and English text at the same time. After many rounds of learning, the model can now deal with daily topics like shopping, school, and work. But it still finds finger spelling and regional (宗教的) signs hard. The team still keeps working on it. ④SignGemma is light—it can live on a phone that has only 2 GB of RAM. Google gives app builders free tools: a TensorFlow Lite file, sample code on GitHub, and a small API. In tests, a student can open an app, sign “Where is the library?”, and see the sentence on the screen right away. ⑤Google has a bigger dream for SignGemma in the future. If a deaf child can ask questions in class without waiting for a human helper, learning becomes smoother. If a deaf adult can order food alone, life becomes freer. Google hopes developers, schools, and hospitals will add SignGemma to their own apps and make public places friendlier for deaf people. ⑥But Google also says SignGemma is not perfect. It may miss fast signs or strong accents. For legal talks or doctor visits, a trained human interpreter (翻译) is still the safer choice. The company asks users to send feedback so the model can keep learning and cover more sign languages in the future. ⑦For now, SignGemma is a preview, open to a small group. A full release (发布) is planned for late 2025. When that day comes, a simple phone camera may become a bridge between two worlds—hands that speak and ears that listen. 1．Why does Google make SignGemma? A．To teach deaf people how to spell English words. B．To turn American Sign Language into English text. C．To help hearing people learn ASL through games. D．To record sign-language videos for the cloud. 2．What can we learn about SignGemma? A．It needs strong cloud Internet. B．It gives results in a very short time. C．It can understand regional signs without difficulty. D．Google asks money from developers for its tools. 3．What does Google hope SignGemma will achieve in the future? A．It will become the most popular AI model for language translations. B．It will be used in more places to make public areas friendlier for deaf people. C．It will mainly be used in hospitals to help deaf patients talk with doctors. D．It will take the place of all human helpers for deaf people in daily life. 4．Which of the following structure diagrams correctly shows the main idea of the passage?(Note: Para.=Paragraph) A． B． C． D． 学科网（北京）股份有限公司 $ Unit 3 Our digital lives 单元话题阅读理解 Unit 3 Our digital lives单元话题：科学技术 本资料共10篇专题训练，从上到下依次按照难度分为基础语篇巩固练和重难语篇提升练 基础语篇巩固练 “Could you please plan a four-day trip for a family to Jilin Province in northeast China?

Although it might sound a little far from you, living in a “smart” city like this could happen sooner than you think. Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a “telepresence system” (远程呈现系统)—allowing users to control the heating and locks, take part in video meetings, and receive education, healthcare and government services. Around the city, escalators (自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system. The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business. About 75% of the world’s population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. “Making cities smarter is one way out, and I think this will in turn make cities greener,” said Dan Hill, head of a research company. 1．According to the text, living in a “smart” city _______.

The film surprised many people with its amazing visual effects (视觉效果) and created new ways to show classic stories. AI gives breathtaking visual effects and emotional experiences. The blogger, Mr. Feng, has 15 years of art experience. He said that a video, which would take at least six months to make without AI, was done in a week with AI’s help. He also talked about how to make videos with AI. Using the first part of “Journey to the West” as an example, he talked about how to decide how many pictures and storyboards are needed. He said he used ChatGPT to analyze (分析) the original text, plan the storyboards, draw with AI painting software, and then turned the pictures into a video. These processes usually create a lot of early versions (版本). “Right now, it’s hard for AI to fully understand what I mean, so the results are kind of random (随意的). Every time, I use AI to form a lot of materials to find the right one for the next step,” Mr. Feng said. When it comes to adding exciting fight scenes to the “Journey to the West” TV series and other works, Feng pointed out that there are still many limitations in AI-made videos, making it hard to do such scenes. 1．Why did the AI-made film surprise many people according to the text? A．It was created by a blogger from Sichuan. B．It showed a story with amazing visuals. C．It was shared on the Internet. D．It was the first AI-made film. 2．How long will it take AI to make a film which takes people a year to make? A．At most a week. B．At least six months. C．About two weeks.

D．He doesn’t care about its development in film making. 【答案】1．B 2．C 3．B 4．D 5．B 【导语】本文介绍了一位四川博主利用AI技术制作了《西游记》动画短片，展示了AI在视觉效果和创作效率上的优势，同时也指出了AI在视频制作中的局限性。 1．细节理解题。根据“The film surprised many people with its amazing visual effects (视觉效果) and created new ways to show classic stories.”可知，AI制作的电影因其惊人的视觉效果和展示经典故事的新方式而令人惊讶。故选B。 2．推理判断题。根据“He said that a video, which would take at least six months to make without AI, was done in a week with AI’s help.”可知，没有AI需要至少六个月制作的视频，在AI的帮助下只需一周。因此，如果人们需要一年制作，AI可能最多只需两周。故选C。 3．细节理解题。根据第四段内容“He said he used ChatGPT to analyze (分析) the original text, plan the storyboards, draw with AI painting software, and then turned the pictures into a video”可知，这一段回答了使用AI创建视频的步骤。故选B。 4．词句猜测题。根据“making it hard to do such scenes”可知，AI制作的视频在添加激动人心的打斗场景时存在困难，因此“limitations”意为“缺点”或“不足”。故选D。 5．观点态度题。根据“Feng pointed out that there are still many limitations in AI-made videos, making it hard to do such scenes.”可知，冯先生认为AI在制作视频时仍面临挑战。故选B。 重难语篇提升练 Getting a dream job has never been easy, but at least in the past you knew that the person you had to move was a human being. However, recently, more bosses are putting the work of finding the most acceptable worker on the inhuman shoulders. AI systems can read through thousands of resumes (简历) much faster than a person or even a group of people. What’s more, AI programs have been invented to run video interviews, too. While those who support such systems believe that this super useful hiring (雇佣) method is the future, others fear that the systems have serious problems. Because AI systems use unfair information to learn how to choose people, the hiring process (过程) may actually be more unfair when AI is used. A recent example of this was Amazon’s AI-hiring system, which paid no attention to women because most technical workers were men. Naturally, people who look for jobs are trying anything they can to satisfy the AI’s selection (选择) standards. Now, in South Korea a number of the top companies use AI for hiring. In order to get jobs, people attend special schools to learn how to pass their AI interviews. Of course, many of the skills taught in special schools are only educated (有根据的) guesses. Without knowing exactly what kind of person AI system looks for, knowing what to do to please it is very difficult, However, there are still some things you can try. For example, try to use special words in your interview answers because AI often searches information for special key words. Another tip is to make your resumes simple. That way, the AI can search it more easily. It seems our success could depend too much on the magical decision of a machine mind. It sounds unfair, and it may be. In the end, the power to either change the system itself or at least make it work for you is in your hands as long as you make up your mind. 根据语篇内容，按要求回答问题。 1．What does the underlined phrase “the inhuman shoulders” refer to (指的是)? A．AI systems. B．Bosses. C．Workmates. 2．What does the writer think of Amazon’s AI-hiring system? A．It knows about women. B．It’s not fair to women. C．It prefers to choose women. 3．What do people do to satisfy the AI’s selection standards? A．They learn how to pass their AI interview. B．They try to learn how to use computers. C．They write letters to some AI companies. 4．What does the underlined word “please” in Paragraph 4 mean? A．请便 B．选择 C．(使)满意 5．What’s the best title for the passage? A．Making up your mind B．Hired by a machine mind C．Amazon’s AI-hiring system 【答案】1．A 2．B 3．A 4．C 5．B 【导语】本文是一篇说明文。文章客观介绍了人工智能在招聘领域的应用现状，包括其高效处理简历、进行视频面试的功能优势，以及系统可能因数据偏差导致公平性问题的技术缺陷（如亚马逊案例）。同时说明了求职者为应对AI筛选所采取的措施，并列举了提升通过率的实用方法，全面呈现了AI招聘技术的发展与影响。 1．词句猜测题。根据文章第一段“However, recently, more bosses are putting the work of finding the most acceptable worker on the inhuman shoulders. Al systems can read through thousands of resumes (简历) much faster than a person or even a group of people.”可知，越来越多的老板将寻找最合适员工的工作交给了非人类的肩膀，即AI系统，因为AI系统能比人或人群更快地阅读成千上万的简历。因此，“the inhuman shoulders”指的是AI系统。故选A。 2．推理判断题。根据文章第二段“A recent example of this was Amazon’s Al-hiring system, which paid no attention to women because most technical workers were men.”可知，亚马逊的AI招聘系统忽视了女性求职者，因为大多数技术工人是男性。由此推断，作者认为这个系统对女性不公平。故选B。 3．细节理解题。根据文章第三段“Now, in South Korea a number of the top companies use Al for hiring. In order to get jobs, people attend special schools to learn how to pass their AI interviews.”可知，为了获得工作，人们参加特殊学校学习如何通过AI面试，以满足AI的选择标准。故选A。 4．词句猜测题。根据文章第四段“Without knowing exactly what kind of person AI system looks for, knowing what to do to please it is very difficult”可知，在不知道AI系统具体寻找什么样的人的情况下，很难知道如何做才能使其满意。因此，“please”在此处的意思是“使（满意）”。故选C。 5．最佳标题题。全文围绕人工智能在招聘过程中的应用及其带来的问题展开讨论，指出虽然AI在招聘中扮演重要角色，但人们仍有能力改变系统或使其为自己服务。因此，最佳标题是“被机器大脑雇佣”（Hired by a machine mind），这个标题既概括了文章的主题，又吸引了读者的注意。故选B。 ①In May 2025, Google shared a piece of news about a new AI model called SignGemma. It is made to understand American Sign Language (ASL) and turn it into English words on a screen. It can help deaf people talk with hearing people more quickly and more easily. ②SignGemma uses a phone camera to catch hand shapes, face moves, and body movements. In less than 200 milliseconds, it writes or speaks the meaning. Because the model works on the device, it does not need the cloud (云盘). That means faster answers, lower data cost, and safer personal information for users. ③To train SignGemma how to understand sign language, Google let it “watch” 10, 000 hours of sign language videos. Each video shows hands, face, and English text at the same time. After many rounds of learning, the model can now deal with daily topics like shopping, school, and work. But it still finds finger spelling and regional (宗教的) signs hard. The team still keeps working on it. ④SignGemma is light—it can live on a phone that has only 2 GB of RAM. Google gives app builders free tools: a TensorFlow Lite file, sample code on GitHub, and a small API. In tests, a student can open an app, sign “Where is the library?”, and see the sentence on the screen right away. ⑤Google has a bigger dream for SignGemma in the future. If a deaf child can ask questions in class without waiting for a human helper, learning becomes smoother. If a deaf adult can order food alone, life becomes freer. Google hopes developers, schools, and hospitals will add SignGemma to their own apps and make public places friendlier for deaf people. ⑥But Google also says SignGemma is not perfect. It may miss fast signs or strong accents. For legal talks or doctor visits, a trained human interpreter (翻译) is still the safer choice. The company asks users to send feedback so the model can keep learning and cover more sign languages in the future. ⑦For now, SignGemma is a preview, open to a small group. A full release (发布) is planned for late 2025. When that day comes, a simple phone camera may become a bridge between two worlds—hands that speak and ears that listen. 1．Why does Google make SignGemma? A．To teach deaf people how to spell English words. B．To turn American Sign Language into English text. C．To help hearing people learn ASL through games. D．To record sign-language videos for the cloud. 2．What can we learn about SignGemma? A．It needs strong cloud Internet. B．It gives results in a very short time. C．It can understand regional signs without difficulty. D．Google asks money from developers for its tools. 3．What does Google hope SignGemma will achieve in the future? A．It will become the most popular AI model for language translations. B．It will be used in more places to make public areas friendlier for deaf people. C．It will mainly be used in hospitals to help deaf patients talk with doctors. D．It will take the place of all human helpers for deaf people in daily life. 4．Which of the following structure diagrams correctly shows the main idea of the passage?(Note: Para.=Paragraph) A． B． C． D． 【答案】1．B 2．B 3．B 4．A 【导语】本文是一篇说明文，主要介绍了谷歌推出的名为SignGemma的新人工智能模型，包括其功能、优势、训练测试情况、未来愿景以及存在的不足等内容。 1．细节理解题。根据“In May 2025, Google shared a piece of news about a new AI model called SignGemma. It is made to understand American Sign Language (ASL) and turn it into English words on a screen.”（2025年5月，谷歌分享了一条关于名为SignGemma的新人工智能模型的消息。它被设计用来理解美国手语，并将其转化为屏幕上的英语单词。）可知，谷歌研发SignGemma是为了将美国手语转化为英文文本。故选B。 2．细节理解题。根据“In less than 200 milliseconds, it writes or speaks the meaning.”（在不到200毫秒的时间内，它就能写出或说出意思。）可知，SignGemma能在很短时间内给出结果。故选B。 3．细节理解题。根据“Google hopes developers, schools, and hospitals will add SignGemma to their own apps and make public places friendlier for deaf people.”（谷歌希望开发者、学校和医院将SignGemma添加到他们自己的应用程序中，让公共场所对聋人更友好。）可知，谷歌希望未来SignGemma能在更多地方被使用，让公共场所对聋人更友好。故选B。 4．篇章结构题。文章第一段介绍SignGemma；第二段讲其优势；第三、四段讲训练与测试；第五至七段讲未来愿景、不足及未来计划。A选项的结构符合文章内容。故选A。 学科网（北京）股份有限公司 $
