More and more people are choosing to spend less time on their phones—not because anyone forces them to, but because they want to. Why are people making this choice? A recent survey found that many phone users often feel anxious (焦虑的) and tired after long hours online. By cutting down screen time, people hope to improve their mental health, focus better on their studies or work, and spend more quality time with family and friends. Interestingly, even Generation Z—young people who grew up with the Internet and spend more time online than any other generation—are now leading this change. Part of the problem is that smartphones and apps are designed to keep us hooked (使上瘾的). Many people open an app for "just five minutes" but end up spending two hours—falling into the trap without even noticing it. So how are people detoxing? Some are buying "dumb phones" (功能手机)—simple phones without social media apps. Others keep their phones out of the bedroom, so mornings start with breakfast or reading instead of scrolling (刷屏). Screen-free meals are also becoming a common family rule: no phones at the table, just real conversation. "Digital detox doesn't mean throwing away your smartphone," explains Dr. Sarah Chen, a psychologist (心理学家). "Technology itself is not the enemy. What we need is to use it with clear intention (意图) and find a healthy balance between our online and offline lives." In the end, digital detox is less about giving up technology and more about taking back control. After all, your life is what you make it—online or offline. 1. What is the main idea of the passage?

What does the underlined phrase "falling into the trap" in Paragraph 3 probably mean? A. Getting caught in a dangerous situation unexpectedly. B. Dropping a phone into water by accident. C. Buying a phone that doesn't work properly. D. Falling down while using a phone. 4. Which of the following is NOT mentioned as a digital detox trend in the passage? A.

Having meals without looking at screens. 5. What can we infer from Dr. Sarah Chen's words in Paragraph 5? A. We should throw away all our smartphones immediately. B. Digital detox means using technology with clear intention and balance. C. Technology companies should stop making addictive apps. D. Only experts know how to use technology properly. Part B 语法填空 Finding Balance in a Digital World In 2026, more and more young people are choosing 1________ (live) a life with less screen time. It is no longer considered strange 2________ (put) your phone away during meals or before bed. In fact, many experts agree that controlling our digital habits is one of 3________ (important) skills for modern teenagers. Take my classmate Tom as an example. He used 4________ (spend) over six hours a day on his phone. His parents were worried and tried 5________ (persuade) him to change. "I want you 6________ (find) a healthier balance," his mother said. Tom's goal was simple — to reduce his daily screen time to under two hours. At first, Tom found 7________ difficult to stay away from social media. But he didn't give up. He was the first student in our class 8________ (join) the "Digital Wellness Club." Every morning, he would get up early and practice running in the park instead of scrolling through his phone. Three months later, Tom has become a different person. He has more energy, better grades, and 9________ (strong) relationships with friends. "The best choice I ever made," he says, "was 10________ (decide) to take control of my own life." Part C 完形填空 My Digital Detox Journey Like many teenagers, I used to be addicted to my smartphone. Every morning, the first thing I did was 1 1 my phone to check social media. I would spend hours scrolling through short videos, 2 that I was "just relaxing." But deep down, I knew something was wrong. I felt tired, anxious, and unable 3 on my studies. One day, my English teacher shared an article about digital detox with our class. She told us that more and more young people were making a 4 choice — to put down their phones and reconnect with the real world. Her words really 5 me. I decided to try a one-week digital detox experiment. The first two days were incredibly hard. I kept 6 for my phone, even when I was eating or walking. But I stuck to my plan. I moved my phone to the living room before going to bed and bought a simple alarm clock 7 my bedroom. I also made a rule: no phones at the dinner table. Slowly, things started to change. Without constant notifications, I found myself 8 more time reading books and talking to my family. I even picked up my old hobby — 9 basketball with my neighbors after school. My sleep improved, and I felt more energetic during the day. Now, three months later, I still use my smartphone, but I use it 10 . I set screen-time limits and turn off unnecessary notifications. I've learned that technology is a tool, not a master. The power to choose how we live 11 in our own hands. This experience taught me an important lesson: sometimes, the best life choice is not about getting more, 12 about letting go. Just like Li Ying in our textbook, who sets clear goals and tries her best 13 them, I have set my own goal — to live a balanced life where technology serves me, not the other way 14 . After all, our life is what we make it. The choices we make today 15 who we become tomorrow. 请从每题所给的 A、B、C、D 四个选项中，选出最佳选项。 1. A. put away    B. reach for    C. look after    D. pay for 2.

Part A 阅读理解 1 B 主旨大意题。全文围绕"数字排毒成为2026年流行的生活方式选择"展开，A 过于极端，C 以偏概全，D 与原文相反（Gen Z 是上网时间最长的群体，却率先引领排毒运动）。 2 C 细节理解题。第一段末句明确指出数字过载对 mental health, focus, sleep, and personal relationships 造成挑战，因此人们选择数字排毒。 3 A 词义猜测题。"falling into the trap of being too distracted" 指"陷入过度分心的陷阱/圈套"，即不知不觉中陷入危险境地。 4 C 细节判断题。A（笨手机）、B（无屏幕早晨）、D（无科技用餐）均在文中提及，C（昂贵的偏远山区静修）未提及。 5 B 推理判断题。Dr. Chen 强调"控制使用技术的时间、方式和原因"，"目标不是缺席，而是平衡和自主"，即 intention + balance。 Part B 语法填空 1 to live 非谓语动词 · 不定式choose to do sth 选择做某事。不定式作宾语。 2 to put 非谓语动词 · 不定式It is + adj. + to do sth. 真正主语后置，it 为形式主语。 3 the most important 形容词 · 最高级"one of + the + 形容词最高级 + 名词复数" 结构，表示"最…一"。 4 to spend 非谓语动词 · 不定式used to do sth 过去常常做某事（现在已不做）。注意区分 be used to doing（习惯于）。 5 to persuade非谓语动词 · 不定式try to do sth 努力/试图做某事。try doing 表"尝试做（看效果如何）"。 6 to find非谓语动词 · 不定式want sb to do sth 想要某人做某事。不定式作宾语补足语。 7 it代词 · 形式宾语find it + adj. + to do sth. it 作形式宾语，真正宾语是后面的不定式短语。 8 to join非谓语动词 · 不定式the first student to join... 序数词（the first）后接不定式作后置定语。 9 stronger形容词 · 比较级由前文 more energy, better grades 可知此处为并列比较级，strong → stronger。 10 to decide / deciding非谓语动词 · 不定式/动名词was to decide / was deciding 均可。不定式更强调具体的一次性决定；动名词强调抽象概念。在语法填空中通常优先填 to decide。 Part C 完形填空 1 B reach for 伸手去拿。早晨第一件事是"伸手去拿手机"，符合 addicted 的语境。 2 A pretending 假装。假装自己"只是在放松"，实则沉迷。 3 B unable to focus 无法集中注意力。unable 后接不定式。 4 C conscious 有意识的、自觉的。与 Unit 1 主题"生活选择"呼应，指"有意识的选择"。 5 A moved 感动。老师的话"打动/感动"了我，促使我做出改变。 6 C reaching for 伸手去够。与第1题 reach for 呼应，形成词汇复现。 7 A buy sth for... 为……买某物。为卧室买了一个简单闹钟。 8 A find oneself doing sth 发现自己正在做某事。spending 作宾补。 9 C playing basketball 动名词作介词 of 的宾语（pick up doing）。 10 B more carefully 更仔细地。修饰动词 use，用副词比较级。 11 A lies in 在于。The power... lies in our own hands. 权力掌握在我们自己手中。 12 C not... but... 不是……而是……。最好的生活选择不是得到更多，而是学会放下。 13 B try one's best to do sth 尽最大努力做某事。try one's best 后接不定式。 14 C the other way around 反过来。技术为我服务，而不是反过来。 15 C lead to 导致、造就。今天的选择造就明天的我们。 1 学科网（北京）股份有限公司 $
