But do you know how to tell if the food is safe? Now, digital identity (数字身份) is making this question easy 2 (answer). When my mom buys apples at the market, she always scans the small code (扫码) on the apple box. This code is the 3 (apple) digital identity. It tells us where the apples grow, when they 4 (pick). That makes her feel relaxed. My dad works 5 a food shop. He says digital identity helps his work a lot. Every morning, he checks the digital identity of the new food deliveries (食品配送). If the identity information is missing, he won’t put 6 food on the shelf. Once, a customer asked about the safety of the milk. Dad showed him the digital identity on the phone, and the customer bought it 7 (happy). At school, our biology teacher tells 8 (we) about food safety too. She says digital identity is like a “safety card” for food. For example, when we order takeaway chicken rice, we can check the restaurant’s digital identity on the app first. It shows if the restaurant is clean 9 healthy. Now I know digital identity is not just a code. It keeps us safe when we eat. This kind of digital identity is very 10 (help) for our health. The code on food packages works well to show safety details. 【答案】 1．vegetables 2．to answer 3．apple’s 4．are picked 5．in 6．the 7．happily 8．us 9．and 10．helpful 【导语】本文主要介绍了食品的数字身份（二维码）如何帮助消费者了解食品来源、生产时间和安全性，从而保障食品安全健康。 1．句意：我们每天都会购买、食用各式各样的食物，比如蔬菜和水果。different kinds of后面接可数名词复数；vegetable是可数名词，与复数fruits并列，所以变复数vegetables。 2．句意：如今，数字身份让这个问题变得很容易解答。主语+make sth.+形容词+to do表示“做某事是…… 的”；easy to answer表示 “容易回答”，不定式主动表被动。 3．句意：这个二维码就是这个苹果的数字身份。根据句意“这个二维码是苹果的数字身份”可知，此处表示所属关系，用名词所有格apple’s。 4．句意：它会告诉我们苹果的种植产地、采摘时间。主语they指代apples，苹果是“被采摘”，要用被动语态；主句谓语动词tells和grow都是一般现在时，主语“they”是复数，be动词用are，pick过去分词为picked。 5．句意：我的爸爸在一家食品店上班。work in+小店铺、场所，表示“在……里面工作”。 6．句意：如果缺少身份信息，他就不会把这批食品摆上货架售卖。此处food特指前文刚提到的这批新配送食品，表特指要用定冠词the。 7．句意：爸爸在手机上给他出示了数字溯源码，这位顾客便开心地买下了牛奶。修饰动词bought需要用副词；happy形容词变副词happily，意为“开心地”。 8．句意：在学校，我们的生物老师也会给我们讲解食品安全相关知识。动词tell后面要用人称代词宾格作宾语，we的宾格为us。 9．句意：它可以显示这家餐馆是否干净卫生。clean（干净的）与healthy（卫生健康的）是两个并列形容词，并列连词用and。 10．句意：这类食品数字溯源身份对我们的健康十分有益。be动词后需要形容词作表语，help的形容词为helpful。be helpful for意为“对……有帮助”，符合语境。 二、选词填空。 （25-26九年级上·山东德州·期末）阅读下列短文、根据短文内容，从每个方框内所给11个词汇中选择10个意义相符的词，必要时进行词形变化，填入空白处。 why, with, advantage, two, quick, book, but, they, on, convenient, and E-book is short for electronic book. It is usually read on personal computers. Some mobile phones, can also be used to read e-books. Earlier e-books were written for a small group of readers and were about only a few subjects. 1 the development of the Internet, knowledge and answers to a lot of questions mainly come from e-books. This is 2 the e-book business is increasing quickly. E-books have many 3 . First, they save time. We don’t need to go to a bookstore to buy 4 . Besides, we can find the topic we want to know about on the Internet, and then we can 5 get many e-books on similar topics. 6 , e-books save money. Some e-books cost a little money, and there are millions of e-books 7 the Internet which we can get for free. Third, more trees are saved because e-books don’t need to be printed on paper. Fourth, e-books make reading 8 than before. We can carry a whole library of hundreds of books with us in a small computer or any e-book reader (电子阅读器) without worrying about 9 weight. 10 e-books have certain disadvantages. They need a personal computer or an e-book reader and the information can be lost if its file format (文件格式) is not supported or changed in the reader’s computer. However, e-books provide us with a new way of reading. That is good. 【答案】 1．With 2．why 3．advantages 4．books 5．quickly 6．Second 7．on 8．more convenient 9．their 10．But 【导语】本文是一篇说明文，讲述了电子书兴起的缘由、四大优势以及存在的缺点。 1．句意：随着互联网的发展，知识和许多问题的答案主要来源于电子书。“With the development of...” 意为“随着……的发展”，为常见固定搭配。位于句首，首字母需大写。 2．句意：这就是电子书行业发展迅猛的原因。“This is why...” 意为“这就是为什么……”，引导表语从句，解释前文现象导致的结果，符合逻辑。 3．句意：电子书有许多优点。根据下文列举的First, Second, Third, Fourth可知，段落主要介绍电子书的好处。many后需接可数名词复数，故将advantage变为advantages。 4．句意：我们不需要去书店买书。book为可数名词，此处泛指书本，应用复数形式books。 5．句意：然后我们就能快速地获取许多相似主题的电子书。此处需要一个副词来修饰动词get，故将形容词quick变为副词quickly。 6．句意：第二，电子书省钱。根据前文的First和后文的Third, Fourth排序提示可知，此处对应第二，two变为序数词Second。位于句首，首字母需大写。 7．句意：互联网上有数以百万计的免费电子书。“on the Internet” 意为“在互联网上”，为固定介词搭配。 8．句意：第四，电子书让阅读比以前更方便。根据空后的比较连词than可知，此处需用形容词的比较级形式，故填more convenient。 9．句意：我们可以随身携带包含数百本书的整个图书馆，只需一个小型电脑或任何电子阅读器，而无需担心重量问题。此处指代前面提到的“成百上千本书（hundreds of books）”的重量，需用they的形容词性物主代词their来修饰名词weight。 10．句意：但是电子书也有一些缺点。前文大篇幅讲述了电子书的优点，此处话锋一转开始讲述缺点（disadvantages），前后语境构成明显的转折关系，故填But。位于句首，首字母需大写。 一、完形填空 （25-26九年级下·黑龙江大庆·期中）Artificial Intelligence (AI) has become a powerful helper for teenagers’ learning in 2026. It brings new changes to how we study and makes learning more 1 and efficient. Unlike traditional learning tools, AI can understand each student’s learning habits and 2 personalized study plans. For example, when a student has trouble with English grammar, AI can provide specific exercises and explain mistakes in simple language. It can also work as a “24-hour tutor”—whenever you feel puzzled, you can ask AI for help 3 waiting for teachers or parents. This helps students build confidence and learn at their own 4 . However, AI is not a “magic tool” that can replace hard work. Some students may 5 too much on AI and stop thinking independently. To use AI well, we need to remember that it is just a helper, not a 6 . We should use it to solve difficult problems and improve our skills, not to finish homework 7 . Schools and teachers are also working to help students use AI properly. They organize activities to teach students how to 8 useful information from AI and how to avoid its shortcomings. With the right use of AI, teenagers can learn smarter, not just 9 . In the future, AI will continue to develop and bring more surprises to our learning. It is important for us to keep an open mind and 10 this new technology wisely. 1．A．boring B．interesting C．difficult D．tiring 2．A．create B．change C．check D．copy 3．A．instead of B．because of C．in case of D．in order to 4．A．time B．speed C．place D．age 5．A．depend B．call C．spend D．take 6．A．teacher B．student C．friend D．parent 7．A．carefully B．slowly C．carelessly D．happily 8．A．hide B．collect C．waste D．forget 9．A．harder B．quieter C．clearer D．earlier 10．A．refuse B．avoid C．use D．sell 【答案】 1．B 2．A 3．A 4．B 5．A 6．A 7．C 8．B 9．A 10．C 【导语】本文主要介绍了人工智能 (AI) 在青少年学习中的作用，既阐述了它带来的便利，也提醒学生合理使用AI、避免过度依赖。 1．句意：它给我们的学习方式带来了新的变化，也让学习变得更加有趣、更高效。 前文提到AI为学习带来新变化，后文与“efficient”并列，需填褒义形容词，表示学习变得更有趣高效，interesting“有趣的”符合语境；boring“无聊的”、difficult“困难的”、tiring“累人的”均与语境不符。 2．句意：与传统学习工具不同，人工智能能够了解每位学生的学习习惯，并制定个性化的学习计划。 本句缺少谓语动词，结合语境，AI可根据学习习惯量身打造学习计划，create“制定；创造”符合语境；change“改变”、check“检查”、copy“复制”均不符合句意逻辑。 3．句意：它还可以充当一位“24小时辅导老师”——每当你感到困惑时，都可以向人工智能求助，而不必等候老师或家长。 前后为取舍关系，向AI求助不用等候师长，instead of“而不是”符合语境；because of “因为”、in case of“万一”、in order to“为了”均不符合逻辑关系。 4．句意：这有助于学生树立自信，并按照自己的学习进度去学习。 固定搭配at one’s own speed意为“按照自己的节奏/进度”，贴合自主学习语境，speed“进度；速度”符合用法；time“时间”、place“地点”、age“年龄”均不符合固定搭配与句意。 5．句意：一些学生开始过度依赖人工智能，不再独立思考。 后文提到不再独立思考，说明存在过度依靠AI的情况，depend on“依赖”为固定搭配，depend符合语境；call“呼叫”、spend“花费”、take“拿取”均不能与on搭配表依赖含义。 6．句意：要想用好人工智能，我们要记住它只是一个助手，而不能替代老师。 结合语境，AI只是辅助工具，无法代替师长引导学习，teacher“老师”符合语境；student “学生”、friend“朋友”、parent“父母”均不符合句意。 7．句意：我们应该用它来攻克难题、提升能力，而不是敷衍地完成作业。 前后表转折，应合理用AI学习，而非草率应付作业，carelessly“粗心地；敷衍地”符合语境；carefully“认真地”、slowly“缓慢地”、happily“开心地”均与转折语义不符。 8．句意：他们组织活动，教导学生如何从人工智能中搜集有用信息，以及如何规避它的不足之处。 语境指从AI当中搜集、获取有用学习资讯，collect“收集；获取”符合句意；hide“隐藏”、waste“浪费”、forget“忘记”均不符合教育引导的本意。 9．句意：合理使用人工智能，青少年可以学得更巧妙，而不只是一味死学苦学。 前后形成对比，强调巧学优于苦学，harder“更努力地”符合对比语境；quieter“更安静地”、clearer“更清晰地”、earlier“更早地”均不符合句意逻辑。 10．句意：我们要保持开放的心态，明智地使用这项新技术，这一点很重要。 前文提倡包容接纳AI，此处指合理使用科技，use“使用”符合语境；refuse“拒绝”、avoid“回避”、sell“售卖”均与文意导向相悖。 二、阅读理解。 （2026·山东滨州·二模）What would life be like if AI (artificial intelligence) solved all your problems? You wouldn’t have to work anymore. You could get anything you wanted by just moving a finger. You could feel pleasure whenever you wanted. Death would become almost a choice— you could turn into a digital form and keep going for a million years. All that sounds terrible to me. It’s true that humans don’t like problems. But if we had no problems to solve, what would be the point of living? How long would we be happy sitting on top of our big mountains of candy? For me, a long weekend would be enough. A million years of perfect happiness would feel like a terrible dream. Professor Nick Bostrom from a famous university believes that even if AI could do everything perfectly, people might still “work” at “jobs” in “offices”. “But these jobs would really be more like hobbies.” That wouldn’t be a problem, you might say, as people could stay busy doing other things. They could go shopping, do some gardening or take care of your children. But one reason people get satisfied with such things is that they pride themselves on being good at them. However, AI will probably do these all better than you. In a world like that, you might feel like you’re doing more harm than good to your child if you try parenting on your own. But life in that “perfect” world might still be bearable, says Bostrom. For example, we could ask our computers to give us interesting tasks. In Greg Egan’s sci-fi novel Permutation City, a man forces himself to develop new hobbies every now and then to keep from being bored. He finds joy in making table legs and ends up making 162, 329 of them. Bostrom suggests we not rush to make a decision. We might end up liking the future. “The question here is not how interesting a future is to look at, but how good it is to live in,” he says. 1．What does the writer think of a million years of perfect happiness? A．It would be a wonderful dream. B．It would feel like a terrible dream. C．It would make people more hard-working. 2．The underlined word “bearable” in Paragraph 5 most probably means “________”. A．easy to forget B．easy to accept C．easy to change 3．We can infer from the passage that ________. A．AI will definitely make people lose all happiness B．people might feel useless if AI does everything better C．Greg Egan’s novel shows AI will destroy human life 4．What is Professor Bostrom’s attitude towards the AI future? A．Fully against. B．Blindly optimistic. C．Cautiously open-minded. 【答案】1．B 2．B 3．B 4．C 【导语】本文是一篇议论文，探讨了人工智能彻底解决人类所有问题的完美世界是否值得向往，分析了绝对幸福的弊端，并介绍了学者Bostrom对AI未来审慎包容的看法。 1．第二段提到：“A million years of perfect happiness would feel like a terrible dream.”，作者认为一百万年的极致幸福会像一场糟糕的梦。 2．画线单词bearable出现在第五段首句，后文紧接着给出解释：我们可以让电脑安排有意思的任务，还可以像小说人物一样培养新爱好来打发时间。由此可以推断，即便一切都由AI代劳，这种完美世界的生活依旧是可以忍受、能够接受的，对应B选项。easy to forget“容易忘记”，easy to change“容易改变”，均不符合语境。 3．第四段提到：“However, AI will probably do these all better than you. In a world like that, you might feel like you’re doing more harm than good to your child if you try parenting on your own.”，如果人工智能在做家务、育儿等所有事情上都远超人类，人类会丧失自我价值感，觉得自己毫无用处，对应B选项。A选项中“definitely（绝对地）”表述过于绝对，文章并未说AI一定会夺走人类所有快乐；小说只是举例说明靠新爱好排解无聊，并非表达AI会摧毁人类生活，因此C选项错误。 4．最后一段提到：“Bostrom suggests we not rush to make a decision. We might end up liking the future.”以及他的原话可知，他既没有全盘否定AI未来，也没有一味吹捧、盲目看好，而是建议人们暂缓定论、客观看待，体现出谨慎且开放包容的态度，对应C选项。 （2025·北京·中考真题）People are talking a lot about artificial intelligence (AI), viewing it as a force that could reshape how society works. But there is something important missing from this discussion. It isn’t enough to ask how it will change us. We also need to understand how we shape AI and what it can tell us about ourselves. Every AI model we develop mirrors our rules and expresses our beliefs. A few years ago, while looking for new workers, a famous company gave up an AI-powered tool after finding it unfavorable to women. The AI was not designed to behave this way, instead, it was influenced by the historical data (数据) favoring men. Similarly, a recent study found that lending algorithms (算法) often offer less favorable terms to colored people, worsening long-standing unfairness in money-lending business. In both cases, AI isn’t creating new biases (偏见), it is mirroring the ones that are already present. These reflections (反映) give us an important chance to take a close look at ourselves. By making these problems seen and more pressing, AI challenges us to recognize and address what causes algorithmic bias. As AI continues to develop, we must ask ourselves how we as average people want to shape its role in society. We should not only improve AI models, but also make sure that AI is developed and used responsibly. A number of companies are already taking action. They are judging the data, rules, and beliefs that shape the behavior of AI models. Still, we cannot expect the companies to do all the work. As long as AI is trained on human data, it will reflect human behavior. That means we have to think carefully about the footprints of ourselves we leave in the world. I may value privacy, but if I give it up in a heartbeat to visit a website, the algorithms may make a very different judgment of what I really want and what is good for me. If I want meaningful human connections yet spend more time on social media and less time in the physical company of my friends, I am indirectly training AI models about the true nature of humanity. As AI becomes more powerful, we need to take increasing care to read our principles (原则) into the record of our actions rather than allowing the two to diverge. Recognizing this allows us to make better decisions, but only when we are prepared to look closely and take responsibility for what we see. 1．Why does the writer introduce the two examples in Paragraph 2? A．To suggest a solution. B．To stress a difference. C．To challenge a practice. D．To support a viewpoint. 2．What does the word “diverge” in the last paragraph most probably mean? A．Improve. B．Appear. C．Separate. D．Repeat. 3．According to the passage, what is a good example of shaping AI responsibility? A．Guarding one’s privacy against AI models. B．Being mindful of our feeds into AI models. C．Training algorithms to favor the latest data. D．Designing algorithms to deal with unfairness. 4．Which of the following is the best title for this passage? A．AI Isn’t the Problem; We Are B．AI: A Tool to Reshape Our Society C．More Open algorithms for Better AI? D．Building Trust in Human-AI Relationships 【答案】1．D 2．C 3．B 4．A 【导语】本文是一篇议论文，主要讨论了人工智能如何反映人类社会中的偏见和不公平现象，并强调人类在塑造AI时需要承担的责任。文章通过具体案例说明AI并非独立产生偏见，而是反映了人类社会已有的问题，并呼吁人们通过自身行为来影响AI的发展方向。 1．推理判断题。根据第二段“In both cases, AI isn’t creating new biases (偏见), it is mirroring the ones that are already present.”可知，作者认为AI并没有创造新的偏见，而是反映了已经存在的偏见。第二段中提到的招聘时由AI驱动的工具对女性更不利，贷款算法对有色人种更为不利，这两个例子印证了作者的观点，是为了支持“AI反映人类社会偏见”这一观点。故选D。 2．词句猜测题。根据“we need to take increasing care to read our principles (原则) into the record of our actions rather than allowing the two to diverge.”可知，在人工智能发展的过程中，我们需要将我们的原则融入到我们的行动记录中，而不是让两者背道而驰。划线部分diverge意为“分歧，背离”，与Separate表达的意思相近。故选C。 3．推理判断题。根据“As long as AI is trained on human data, it will reflect human behavior. That means we have to think carefully about the footprints of ourselves we leave in the world.”可知，只要AI是基于人类数据训练的，它就会反映人类行为。这意味着我们必须认真思考我们在世界上留下的足迹。作者认为人类应谨慎对待自身行为对AI的影响，即“注意我们对AI模型的输入”。故选B。 4．最佳标题题。通读全文可知，文章核心观点是AI并非问题的根源，而是人类社会偏见的反映，因此人类需要为AI的发展负责。选项A“AI Isn’t the Problem; We Are”最贴合主旨。故选A。 $Unit 1 Information and Media Lesson 2分层作业 A组 巩固过关 C组 思维拔高 B组 能力进阶 拓展 链接中考 ( 词汇 collect information 搜集信息 trust v. 相信；信赖 cross-check v. 交叉核查 source n. 来源；资料出处 research v.&n. 研究；调研 climate change 气候变化 international organisation 国际组织 report n. 报告 fact n. 事实 句型 1.

Death would become almost a choice— you could turn into a digital form and keep going for a million years. All that sounds terrible to me. It’s true that humans don’t like problems. But if we had no problems to solve, what would be the point of living? How long would we be happy sitting on top of our big mountains of candy? For me, a long weekend would be enough. A million years of perfect happiness would feel like a terrible dream. Professor Nick Bostrom from a famous university believes that even if AI could do everything perfectly, people might still “work” at “jobs” in “offices”. “But these jobs would really be more like hobbies.” That wouldn’t be a problem, you might say, as people could stay busy doing other things. They could go shopping, do some gardening or take care of your children. But one reason people get satisfied with such things is that they pride themselves on being good at them. However, AI will probably do these all better than you. In a world like that, you might feel like you’re doing more harm than good to your child if you try parenting on your own. But life in that “perfect” world might still be bearable, says Bostrom. For example, we could ask our computers to give us interesting tasks. In Greg Egan’s sci-fi novel Permutation City, a man forces himself to develop new hobbies every now and then to keep from being bored. He finds joy in making table legs and ends up making 162, 329 of them. Bostrom suggests we not rush to make a decision. We might end up liking the future. “The question here is not how interesting a future is to look at, but how good it is to live in,” he says. 1．What does the writer think of a million years of perfect happiness? A．It would be a wonderful dream. B．It would feel like a terrible dream. C．It would make people more hard-working. 2．The underlined word “bearable” in Paragraph 5 most probably means “________”. A．easy to forget B．easy to accept C．easy to change 3．We can infer from the passage that ________. A．AI will definitely make people lose all happiness B．people might feel useless if AI does everything better C．Greg Egan’s novel shows AI will destroy human life 4．What is Professor Bostrom’s attitude towards the AI future? A．Fully against. B．Blindly optimistic. C．Cautiously open-minded. （2025·北京·中考真题）People are talking a lot about artificial intelligence (AI), viewing it as a force that could reshape how society works. But there is something important missing from this discussion. It isn’t enough to ask how it will change us. We also need to understand how we shape AI and what it can tell us about ourselves. Every AI model we develop mirrors our rules and expresses our beliefs. A few years ago, while looking for new workers, a famous company gave up an AI-powered tool after finding it unfavorable to women. The AI was not designed to behave this way, instead, it was influenced by the historical data (数据) favoring men. Similarly, a recent study found that lending algorithms (算法) often offer less favorable terms to colored people, worsening long-standing unfairness in money-lending business. In both cases, AI isn’t creating new biases (偏见), it is mirroring the ones that are already present. These reflections (反映) give us an important chance to take a close look at ourselves. By making these problems seen and more pressing, AI challenges us to recognize and address what causes algorithmic bias. As AI continues to develop, we must ask ourselves how we as average people want to shape its role in society. We should not only improve AI models, but also make sure that AI is developed and used responsibly. A number of companies are already taking action. They are judging the data, rules, and beliefs that shape the behavior of AI models. Still, we cannot expect the companies to do all the work. As long as AI is trained on human data, it will reflect human behavior. That means we have to think carefully about the footprints of ourselves we leave in the world. I may value privacy, but if I give it up in a heartbeat to visit a website, the algorithms may make a very different judgment of what I really want and what is good for me. If I want meaningful human connections yet spend more time on social media and less time in the physical company of my friends, I am indirectly training AI models about the true nature of humanity. As AI becomes more powerful, we need to take increasing care to read our principles (原则) into the record of our actions rather than allowing the two to diverge. Recognizing this allows us to make better decisions, but only when we are prepared to look closely and take responsibility for what we see. 1．Why does the writer introduce the two examples in Paragraph 2? A．To suggest a solution. B．To stress a difference. C．To challenge a practice. D．To support a viewpoint. 2．What does the word “diverge” in the last paragraph most probably mean? A．Improve. B．Appear. C．Separate. D．Repeat. 3．According to the passage, what is a good example of shaping AI responsibility? A．Guarding one’s privacy against AI models. B．Being mindful of our feeds into AI models. C．Training algorithms to favor the latest data. D．Designing algorithms to deal with unfairness. 4．Which of the following is the best title for this passage? A．AI Isn’t the Problem; We Are B．AI: A Tool to Reshape Our Society C．More Open algorithms for Better AI? D．Building Trust in Human-AI Relationships $
