Four middle school students from different schools share their personal opinions in a city youth forum（青少年交流会）. Lin Zixin, Grade 8 from No. 3 Middle School I think smartphones are my best study helpers. When I meet hard textbook knowledge, I can search clear teaching videos online right away. Every weekend, I make video calls to my grandparents who live in another province（省份）. I also use shopping apps and mobile payment to buy my notebooks and snacks quickly. I set strict rules for myself: I only spend 30 minutes on short videos after all homework is finished. I never touch my phone during study hours. Zhou Junhao, Grade7 from Xingfu Road Middle School I used to lose myself in online games and scroll（滑动浏览）short videos, and I really regret（后悔）it. I often stayed up late staring at my screen last term. I felt sleepy every morning and could not hand in homework on time. My eyes also became sore（酸痛的）easily. Now I put my phone in the living room before bedtime. After school, I play football with my teammates instead of staying alone with a mobile phone. Wen Shuyi, Grade 8 from Luming Junior High I hold a balanced（均衡客观的）view on digital products. It’s true that they bring great convenience（便利）to our daily life, but we must control screen time strictly. I never carry my phone to the dining table. If I want to relax online, I limit（限制）my fun time to forty minutes each day. What’s more, I always remind myself not to post my real photos or phone numbers online, to avoid privacy risks. Chen Boyuan, Grade 9from Chengxin Middle School In my opinion, too much screen time cuts off our face-to-face communication. Lots of my classmates only chat online and seldom（很少）talk with their family members at home. I joined a hiking club last month. Every Saturday, I go hiking with club partners. I hope more teenagers can put down their phones and feel the fun of real offline（线下的）activities. After all four students finished sharing, they reached the same conclusion（结论）: digital devices are just common tools. They can bring us a better life only when we use them wisely, rather than letting them control our daily life. 阅读理解：从A、B、C、D中选出一个正确答案。 ( )1. What does Lin Zixin mainly use her phone for? A.

Shared bikes, mobile payment and food delivery bring great convenience for city people, but they also bring clear troubles. ____1____ You can unlock shared electric bikes anywhere with your phone and pay little money for short trips. You don’t need to take cash when shopping, eating or taking buses—just scan QR codes（二维码）. Online shopping lets people buy daily necessities without going out. ____2____ When it rains heavily or during rush hours, the price of ride-hailing（网约车）will jump high. Many shared bikes are left broken on sidewalks（人行道）, and no workers come to fix them in time.If your phone runs out of power or breaks down suddenly, you can’t buy anything or go out easily. ____3____ What’s more, too many people spend all free time scrolling short videos or playing online games, and they lose face-to-face communication（交流）with their family. Experts say digital tools are only useful helpers. ____4____ It’s wise（明智的）to keep a little cash in bags for special moments. 阅读短文，从下面选项中选出四项填入空白处，使文章内容完整。 A.

I saw four middle school students sitting together. They said hello to each other quickly, then took out their phones right away. They kept scrolling（滑动浏览）short videos until the food arrived. After taking photos of their meals, they ate without talking, still watching their screens. This is phubbing — ignoring（忽视） people around you because of mobile phones. A study says 32% of people get phubbed two or three times every day. Many students check their phones while eating with family or friends. They fear they may miss interesting news online. Too much phubbing brings lots of problems. First, it breaks face-to-face communication（交流）. If you always look at your phone when staying with others, your family and friends will feel lonely. Second, long screen time hurts your eyes easily. Some students feel sleepy in class because they stay up late on phones. Third, sharing photos and personal numbers online may cause privacy（隐私）risks. Teachers and parents give some useful advice. We can set screen time limits for ourselves. Put phones away during dinner and study time. After school, choose outdoor activities like hiking or playing ball games instead of staying at home with mobile phones. Digital tools are helpful, but real-life talk and sports are more important. 阅读理解：从A、B、C、D中选出一个正确答案。 ( )1. What does the word “phubbing” mean in Paragraph 1? A. Sharing photos online B. Ignoring others for phones C. Playing online games D. Watching teaching videos ( )2. How many people get phubbed many times every day according to the study? A. About one third B. Nearly half C. All students D. Few people ( )3. Which problem of phubbing is NOT mentioned in the text? A. Bad for eyesight B. Less communication with people C. Wasting much money on phones D. Risk of losing personal privacy ( )4. What advice do adults give teenagers? A. Never use mobile phones at all B. Limit screen time and do outdoor sports C. Only watch videos after midnight D. Chat online all free time ( )5. What is the main idea of the passage? A. Mobile phones bring great convenience to students B. Phubbing is common and has bad influences C. How to use mobile phones for school study D. Students’ favorite short video apps 【重难词汇梳理】 1. phubbing /ˈfʌbɪŋ/ n. 低头族，低头玩手机忽视他人的行为 2. scroll /skrəʊl/ v. 滑动浏览（手机短视频） 3. ignore /ɪɡˈnɔː(r)/ v. 忽视，不理睬 4. communication /kəˌmjuːnɪˈkeɪʃn/ n. 交流，沟通 5. privacy /ˈprɪvəsi/ n. 隐私 6. risk /rɪsk/ n. 风险 7. limit /ˈlɪmɪt/ n. 限制 8. hike /haɪk/ v. 徒步远行 9. screen /skriːn/ n. 屏幕 10. digital /ˈdɪdʒɪtl/ adj. 数字的 11. influence /ˈɪnfluəns/ n. 影响 【长难句分析】 1. This is phubbing — ignoring people around you because of mobile phones. 翻译：这就是低头行为——因为玩手机而无视身边的人。 解析：破折号用来解释phubbing的含义；because of后接名词短语表原因。 2. If you always look at your phone when staying with others, your family and friends will feel lonely. 翻译：如果你和别人相处时总盯着手机，你的家人和朋友会感到孤单。 解析：if引导条件状语从句；when staying with others是状语从句省略结构，完整为when you are staying with others。 3. We can set screen time limits for ourselves. Put phones away during dinner and study time. 翻译：我们可以给自己设定看屏幕的时长限制，吃饭和学习时把手机收起来。 解析：固定搭配set limits for…为……设立限制；put away 意为“收好，放置一旁”。 【全文翻译】 低头族 一天上午，我去一家小餐馆吃午饭。我看到四名初中生坐在一起。他们匆匆互相打了个招呼，立刻掏出了手机。饭菜上桌前，他们一直在滑动浏览短视频。拍完饭菜照片后，他们全程一言不发地吃饭，目光依旧停留在屏幕上。这就是低头行为：因沉迷手机而忽视身边的人。 一项研究表明，32%的人每天会两到三次遭遇他人低头无视自己的情况。很多学生和家人、朋友聚餐时也要翻看手机，生怕错过网上有趣的资讯。 频繁低头玩手机会引发诸多问题。第一，它会破坏面对面的沟通。和他人相处时只顾看手机，身边的亲友难免心生落寞。第二，长时间看屏幕极易损伤视力。部分学生熬夜玩手机，导致上课昏昏欲睡。第三，在网络发布个人照片、手机号，可能会带来隐私泄露的风险。 老师和家长给出了切实可行的建议：我们可以给自己限定使用电子屏幕的时长，用餐、学习期间将手机收好。放学后多选择徒步、球类等户外活动，不要宅家抱着手机。数码工具固然实用，但现实中的面对面交谈与户外运动更为珍贵。 Passage 2 （改编自2023 北京中考） 100 Days Without a Mobile Phone When was the last time you left home without your smartphone? Many people cannot stand living one day without checking their phones. Phones help us keep in touch with family and friends, but they also make us tired and worried. The writer tried to stop using mobile phones for 100 days. At first, the days were terrible. She feared her friends would forget her. When she had free time, she felt bored with nothing to look at. But three weeks later, great changes happened. Without a phone, she spent more time talking with her parents after dinner. She began reading storybooks and walking in the park every evening. Her sleep became much better because she no longer stayed up scrolling videos. She found she had more time to enjoy real small happy things around her. The writer doesn’t ask everyone to give up phones totally. She gives two simple rules for balanced digital life. First, put phones away during family time. Second, stop using screens one hour before bedtime. Digital devices are just tools, and we should not let them control our life. 阅读理解，回答下列问题。 1. Why do most people hate leaving phones at home? ____________________________________________________________________________________________ 2. How long did the writer stop using mobile phones? ____________________________________________________________________________________________ 3. What trouble did the writer meet in the first few days? ____________________________________________________________________________________________ 4.

Her sleep became much better because she no longer stayed up scrolling videos. 翻译：她的睡眠质量好了很多，因为她不再熬夜刷视频。 解析：because 引导原因状语从句；stayed up 熬夜；scrolling videos 现在分词作伴随状语。 3. Digital devices are just tools, and we should not let them control our life. 翻译：数码设备只是工具，我们不该让它们掌控我们的生活。 解析：并列句由 and 连接；固定搭配 let sb./sth. do sth. 让……做某事。 【全文翻译】 一百天不用手机 你上次出门不带智能手机是什么时候？很多人一天不翻看手机都难以忍受。手机方便我们和亲友保持联络，却也会让人身心疲惫、心生焦虑。 作者尝试整整一百天不使用手机。刚开始那段日子十分难熬，她担心朋友们会渐渐淡忘自己；空闲时没有手机可刷，整个人百无聊赖。但三周之后，巨大的改变悄然发生。 放下手机后，她晚饭后会花更多时间和父母谈心；每天傍晚读故事书、去公园散步。不再熬夜刷短视频，她的睡眠质量大幅提升。她也拥有更多时间，去感受身边真实细碎的美好。 作者并非号召所有人彻底舍弃手机，她给大家两条简单准则，用来平衡线上与现实生活：第一，家人共处时把手机收好；第二，睡前一小时不再使用电子屏幕。数码设备终究只是工具，我们不能让它主宰自己的生活。 Passage 3（改编自 2022年山西中考阅读真题） Digital Reading Living in the age of “Internet+”, more and more electronic products and apps change people’s reading habits. Now most Chinese people like reading on phones or pads instead of paper books. People spend much longer time on e-reading every year. A survey shows that people can remember less information from screens than from real paper books. However, paper books are still popular among many readers. The study says each Chinese person read 7.86 books on average in 2016, much more than before. But teenagers spend too much free time scrolling short videos online, and they hardly read paper books in their daily life. Experts’ advice: We can enjoy the convenience of digital reading, but we should also keep reading paper books. Take a break every 30 minutes when reading on screens to protect your eyesight. 根据文章内容，判断正误（T=True / F=False） ( )1. Few people use electronic devices to read now. ( )2.

I saw four middle school students sitting together. They said hello to each other quickly, then took out their phones right away. They kept scrolling（滑动浏览）short videos until the food arrived. After taking photos of their meals, they ate without talking, still watching their screens. This is phubbing — ignoring（忽视） people around you because of mobile phones. A study says 32% of people get phubbed two or three times every day. Many students check their phones while eating with family or friends. They fear they may miss interesting news online. Too much phubbing brings lots of problems. First, it breaks face-to-face communication（交流）. If you always look at your phone when staying with others, your family and friends will feel lonely. Second, long screen time hurts your eyes easily. Some students feel sleepy in class because they stay up late on phones. Third, sharing photos and personal numbers online may cause privacy（隐私）risks. Teachers and parents give some useful advice. We can set screen time limits for ourselves. Put phones away during dinner and study time. After school, choose outdoor activities like hiking or playing ball games instead of staying at home with mobile phones. Digital tools are helpful, but real-life talk and sports are more important. 阅读理解：从A、B、C、D中选出一个正确答案。 ( )1. What does the word “phubbing” mean in Paragraph 1? A. Sharing photos online B.
