Every day, a large number of people use social media for both work and personal life. ②Social media has many good points. It helps people not only stay connected to their loved ones, but also make new friends. Sam is in the eighth grade. He said,“My best friend moved to another city a year ago, because his father got a new job as a doctor. But thanks to social media, we’re still able to stay in touch every day. I can see what he is doing and share fun moments with him. Social media also lets me meet new people.

What’s more, spending too much time on social media can make people less active in real life. They might miss out on playing outside or talking to people face-to-face. ④In short, social media can be a great tool if we use it in the right way.

OpenAI created it. Since last year, the company 1 (become) one of the world’s fifty most-visited. 2 people ask a question online, they will get the answer to it from the chatbot. The answer reads like an essay (文章). A growing number of 3 (teacher) say it’s too late to keep AI out of their classrooms. In a recent survey, 93% of teachers said they heard of ChatGPT, and 33% used it to think of 4 (create) ideas for classes. In Washington, students used the programme to help 5 their math. In London, a teacher used ChatGPT to simplify (简化) texts for students whose English is not good enough. ChatGPT doesn’t always get things right. But teachers say this can give a way to make students become more interested in study. Some teachers ask students 6 (check) those essays. Sarah Millard, 7 teacher in Rochester, had students critique (评论) a ChatGPT essay on Shakespeare’s Romeo and Juliet. She said students 8 (enjoy) it a lot. Some educators say it would be unfair to other students if teachers let some students use AI to do 9 (them) schoolwork. It’s not clear how AI will change schooling. One thing is certain: There’s no substitute (替代) for human connection. One teacher says, “I high-fived my students. I cried with my students. A computer will never do that. For the chatbot, the key is to use it 10 (correct).” 五、任务型阅读 阅读短文，根据短文内容回答问题。 The world is developing fast because of technology and its uses in our lives. This means that the jobs we have now are changing, and that there will be new jobs in the future. What’s more, you won’t be in the same job your whole working life. It’ll be more likely that you will change jobs every few years—especially when you’re early in your job. There are ways to be prepared for the future jobs by building different job skills. It’s a good idea to start developing these skills early, so you will be ready to jump into these future jobs as they appear. Understanding Digital (数字的) Information Everything is becoming more digital, which means understanding digital information will be important to success in the future jobs. You need to know how to understand and use digital technologies—both software, and hardware—as well as knowing how to read and understand a lot of online information. If you can understand and use digital information, you will be able to learn it quickly and use it to solve problems and make decisions. Being Creative (独创的) No technology can match the creativity of the human mind, and many future jobs will need people to come up with new ideas and put these ideas into real use. This means it is very important to think creatively about problems. If you can imagine ways to solve problems and make new products, you are more likely to be successful in the future jobs. Keeping Learning As new technologies and new jobs appear, it will be more important than ever to be willing to learn new things. Those who can’t or won’t adapt (适应) to these changes will simply get left behind. The workplace is changing fast, and will continue to change. New digital technologies will change nearly every job. So, you should take every chance to learn new skills and technologies, take training classes, and spend time researching and studying up on things that interest you or will be useful for your future jobs. 1．What are the changes in jobs with the development of technology? 2．How can people be prepared for future jobs according to the passage? 3．What is the possible result of not adapting to the changes in future jobs? 4．How will you get ready for the future job? Why? 6 原创精品资源学科网独家享有版权，侵权必究！ 1 / 27 学科网（北京）股份有限公司 $ Unit 3 Our digital lives（复习讲义) 复习要点 1、围绕 Our digital lives（数字生活）主题，梳理数字设备、网络行为相关话题词汇、固定短语与功能句型。 2、重点掌握形容词比较级、最高级的规则变化与特殊不规则变化形式。 3、熟练使用比较等级句型，对不同数字产品、网络生活现象进行对比描述。 4、能结合数字生活话题开展口语交际，并完成观点类简短书面表达。 复习重难点 重点：数字生活主题核心词汇与功能句型；形容词比较等级变化规则、基础句式。 难点：结合语境正确选用比较级、最高级；书面表达中对比观点的组织阐述。 单元考点：单词、短语、句型 知识点1 The internet has brought big changes to everyday life. 互联网给日常生活带来了巨大的变化。（教材P37） ①bring：v. 带来 【变形】bring-brought-brought 【短语运用】：bring sb. sth.= bring sth. to sb. 把某物带给某人; bring big changes to 给……带来重大变化 例句： This song brought us much joy. 这首歌给我们带来了许多欢乐。= This song brought much joy to us. 【bring的其他短语拓展】 bring up 养育，抚养 bring about导致（某种结果）；引起（变化） bring back 带回；使回忆  bring in引入（新事物/人）；赚得（收入） bring out 使显现（隐藏的特质）；出版/推出（书籍、产品） 【即时小练】 1．The smart technology has brought great changes ________ our city.

Social media platforms (平台) allow users to share their thoughts, pictures, and videos with others anytime and anywhere. They are so popular. Every day, a large number of people use social media for both work and personal life. ②Social media has many good points. It helps people not only stay connected to their loved ones, but also make new friends. Sam is in the eighth grade. He said,“My best friend moved to another city a year ago, because his father got a new job as a doctor. But thanks to social media, we’re still able to stay in touch every day. I can see what he is doing and share fun moments with him. Social media also lets me meet new people. Recently, I’ve made a friend from the UK, and we’ve learnt something about each other’s culture.” ③However, there are also some downsides. Sometimes, people compare their lives to the perfect-looking lives in posts and feel sad about their own lives. This can lead to low self-esteem and even depression (抑郁). What’s more, spending too much time on social media can make people less active in real life. They might miss out on playing outside or talking to people face-to-face. ④In short, social media can be a great tool if we use it in the right way. It can help us stay connected and learn new things, but we need to be careful not to let it control our lives. 1．What does the underlined word “They” in paragraph 1 refer to? A．The great thoughts. B．The social media users. C．The social media platforms. D．The pictures and videos shared online. 2．Why does Sam think social media is good? A．It helps him build and keep relationships. B．It helps him get through sad times and stay happy. C．It allows him to share his life with more people. D．It allows him to compare his life with others’. 3．Which saying best shows the writer’s opinion about social media? A．Actions speak louder than words. B．Think twice before you act. C．Every coin has two sides. D．Easy come, easy go. 4．How is the text organized? A．①/②③④ B．①②③/④ C．①/②③/④ D．①②/③/④ 5．What can be the best title for the text? A．Why is social media popular? B．The influence of social media C．How should we build relationships? D．The best way to use social media 【答案】1．C 2．A 3．C 4．C 5．B 【导语】本文是一篇说明文，介绍社交媒体对人们生活的影响，既阐述它便于维系交友的优势，也说明了容易让人自卑、脱离现实生活等弊端，提出只要合理使用，它就能成为好用的工具。 【详解】 1．根据第一段“Social media platforms (平台) allow users to share their thoughts, pictures, and videos with others anytime and anywhere. They are so popular.”They就近指代前面复数名词social media platforms。 2．根据第二段“It helps people not only stay connected to their loved ones, but also make…we’re still able to stay in touch every day…Social media also lets me meet new people.” 可知Sam的例子包含两点：①和老朋友保持联系 ②认识新朋友，核心是维系、建立人际关系。 3．②段讲优点、③段讲弊端、④段总结合理使用就是好工具。文章既讲社交媒体好处，又讲坏处，对应选项C的谚语“事物都有两面”。 4．结构为总-分-总，①段总起引入社交媒体相关话题，②段阐述其优势，③段阐述其弊端，④段总结观点，划分方式为①/②③/④。 5．全文围绕社交媒体给人们生活带来的正面、负面影响展开。 B （25-26八年级上·广东深圳·期末） In the digital age, the Internet of Things (IoT) is a key technology that bridges the physical and digital worlds.

The answer reads like an essay (文章). A growing number of 3 (teacher) say it’s too late to keep AI out of their classrooms. In a recent survey, 93% of teachers said they heard of ChatGPT, and 33% used it to think of 4 (create) ideas for classes. In Washington, students used the programme to help 5 their math. In London, a teacher used ChatGPT to simplify (简化) texts for students whose English is not good enough. ChatGPT doesn’t always get things right. But teachers say this can give a way to make students become more interested in study. Some teachers ask students 6 (check) those essays. Sarah Millard, 7 teacher in Rochester, had students critique (评论) a ChatGPT essay on Shakespeare’s Romeo and Juliet. She said students 8 (enjoy) it a lot. Some educators say it would be unfair to other students if teachers let some students use AI to do 9 (them) schoolwork. It’s not clear how AI will change schooling. One thing is certain: There’s no substitute (替代) for human connection. One teacher says, “I high-fived my students. I cried with my students. A computer will never do that. For the chatbot, the key is to use it 10 (correct).” 【答案】 1．has become 2．When/If 3．teachers 4．creative 5．with 6．to check 7．a 8．enjoyed 9．their 10．correctly 【导语】本文介绍了ChatGPT的功能，讲述其走进校园被师生使用的情况，也提及它的不足与使用价值，指出合理使用是关键且人机联结无可替代。 【详解】 1．句意：自去年以来，该公司已成为全球访问量前五十的公司之一。根据“Since last year”可知，句子要用现在完成时，结构为have/has+过去分词，主语the company是单数，become的过去分词是become。故填has become。 2．句意：当/如果人们在网上提出一个问题时，他们会从这个聊天程序中得到答案。根据“people ask a question online, they will get the answer to it from the chatbot”可知，此处可引导时间状语从句表“当……时”，也可引导条件状语从句表“如果”，用When/If均可，句首首字母大写。故填When/If。 3．句意：越来越多的老师表示，阻止人工智能进入课堂已经太晚了。根据“A growing number of”可知，后接可数名词复数形式，teacher的复数是teachers。故填teachers。 4．句意：在最近的一项调查中，93%的教师表示听说过ChatGPT，33%的教师用它来为课堂构思有创意的想法。根据“to think of...ideas for classes”可知，此处修饰名词ideas，需要用形容词，create的形容词形式是creative。故填creative。 5．句意：在华盛顿，学生们用这个程序来帮助自己学习数学。固定搭配“help with sth.”表示“帮助做某事”，此处填介词with。故填with。 6．句意：一些老师让学生检查这些文章。固定搭配“ask sb. to do sth.”表示“让某人做某事”，此处填check的动词不定式形式to check。故填to check。 7．句意：罗切斯特的一位教师萨拉·米勒德让学生们评论了一篇由ChatGPT写的关于莎士比亚《罗密欧与朱丽叶》的文章。根据“Sarah Millard...teacher in Rochester”可知，此处表示“一位教师”，teacher是以辅音音素开头的单词，用不定冠词a。故填a。 8．句意：她说学生们非常喜欢这个活动。根据前文的had可知，句子时态为一般过去时，enjoy的过去式是enjoyed。故填enjoyed。 9．句意：一些教育工作者表示，如果老师允许一些学生使用人工智能做他们的作业，这对其他学生是不公平的。根据“use AI to do...schoolwork.”可知，此处修饰名词schoolwork，需要用形容词性物主代词，them的形容词性物主代词是their。故填their。 10．句意：对于这个聊天程序来说，关键是正确地使用它。根据“the key is to use it”可知，此处修饰动词use，需要用副词，correct的副词形式是correctly。故填correctly。 五、任务型阅读 阅读短文，根据短文内容回答问题。 The world is developing fast because of technology and its uses in our lives. This means that the jobs we have now are changing, and that there will be new jobs in the future. What’s more, you won’t be in the same job your whole working life. It’ll be more likely that you will change jobs every few years—especially when you’re early in your job. There are ways to be prepared for the future jobs by building different job skills. It’s a good idea to start developing these skills early, so you will be ready to jump into these future jobs as they appear. Understanding Digital (数字的) Information Everything is becoming more digital, which means understanding digital information will be important to success in the future jobs. You need to know how to understand and use digital technologies—both software, and hardware—as well as knowing how to read and understand a lot of online information. If you can understand and use digital information, you will be able to learn it quickly and use it to solve problems and make decisions. Being Creative (独创的) No technology can match the creativity of the human mind, and many future jobs will need people to come up with new ideas and put these ideas into real use. This means it is very important to think creatively about problems. If you can imagine ways to solve problems and make new products, you are more likely to be successful in the future jobs. Keeping Learning As new technologies and new jobs appear, it will be more important than ever to be willing to learn new things. Those who can’t or won’t adapt (适应) to these changes will simply get left behind. The workplace is changing fast, and will continue to change. New digital technologies will change nearly every job. So, you should take every chance to learn new skills and technologies, take training classes, and spend time researching and studying up on things that interest you or will be useful for your future jobs. 1．What are the changes in jobs with the development of technology? 2．How can people be prepared for future jobs according to the passage? 3．What is the possible result of not adapting to the changes in future jobs? 4．How will you get ready for the future job? Why? 【答案】1．There will be new jobs and you won’t be in the same job your whole working life./There will be new jobs./You won’t be in the same job your whole working life./It’ll be more likely that you will change jobs every few years. 2 2．By building different job skills./People need understand digital information, be creative and keep learning./Understand digital information/be creative/keep learning. 3．Getting left behind./People/They will get left behind. 4．I will keep learning new skills and technologies to get ready for the future job, because new jobs will appear in the future. If I don’t keep up with the new skills and technologies, I will fall behind. 【导语】本文主要介绍随着科学技术的发展，未来工作会发生很大变化，为了应对这些变化，我们应该掌握不同的工作技能，不能适应未来变化的人只会落后。 【详解】1．根据“This means that the jobs we have now are changing, and that there will be new jobs in the future. What’s more, you won’t be in the same job your whole working life. It’ll be more likely that you will change jobs every few years—especially when you’re early in your job.”可知未来会有新工作，也不会一辈子只做同一个工作，也有可能每几年就换一次工作，故填There will be new jobs and you won’t be in the same job your whole working life./There will be new jobs./You won’t be in the same job your whole working life./It’ll be more likely that you will change jobs every few years. 2．根据“There are ways to be prepared for the future jobs by building different job skills.”、“Understanding Digital (数字的) Information”、“Being Creative (独创的)”和“Keeping Learning”可知人们可以掌握不同工作的技能、理解数字信息、拥有创造力和持续学习来为未来的工作做准备，故填By building different job skills./People need understand digital information, be creative and keep learning./Understand digital information/be creative/keep learning. 3．根据“Those who can’t or won’t adapt (适应) to these changes will simply get left behind.”可知不能适应未来变化的人会落后于人，故填Getting left behind./People/They will get left behind. 4．开放性题型，答案合理即可。故填I will keep learning new skills and technologies to get ready for the future job, because new jobs will appear in the future.
