同学们好。今天的两组练习聚焦一个和每位备考同学都息息相关的话题——如何在信息洪流中守住专注力。文章难度对标高考，词汇与句式经过原创打磨，仅借鉴近期社会讨论的方向，不照搬任何原文。建议先独立完成，再对照文末答案与解析。
一、阅读理解（共 4 题）
阅读下列短文，从每题所给的 A、B、C、D 四个选项中，选出最佳选项。
Passage
Every time you unlock your phone to glance at a message, you pay a price you cannot see. Psychologists call it "attention residue": a part of your mind remains stuck on the screen even after you put the phone down. For students buried in gaokao revision, this residue is costly. A 2024 experiment showed that teenagers who kept their phones on the desk — even face down and silent — performed worse on a memory test than those who left the devices in another room.
The reason is the "attention economy." Many apps are built to be hard to leave. Their designers study human psychology to keep us scrolling, clicking, and coming back for one more video. Every like gives a small hit of dopamine, training the brain to crave the next reward. Over time, our ability to sit with a difficult maths problem without reaching for the phone grows weaker.
The threat is real, but so is the fix. Researchers suggest a few practical steps. First, create a "phone-free zone" during study hours. Second, use focused time blocks: 25 minutes of deep work followed by a short break. Third, notice your own triggers — do you reach for the phone when a task feels boring or hard? Naming the feeling weakens its pull. Finally, protect your sleep, because a tired brain is a distracted brain.
Focus is not a talent you either have or lack. It is a habit you build, one phone-free hour at a time.

答案：1–4 B C B B
1. 词义理解题。根据第一段 "a part of your mind remains stuck on the screen" 可知，attention residue 指使用后注意力仍停留在屏幕上的状态。选 B。2. 细节题。实验表明手机放在桌上（即使面朝下静音）的学生记忆测试表现更差。选 C。3. 细节题。第二段指出这些应用利用心理学设计，使用户持续滚动、点击、反复返回。选 B。4. 主旨题。作者先说明注意力经济带来的问题，再给出手机隔离区、专注时段、识别触发点、保证睡眠等具体建议。选 B。
二、七选五（共 5 题，36–40）
根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Most students believe they can multitask. Science says otherwise. (36) __________ When you jump between homework and a chat app, your brain pays a "switching cost" — extra time and energy each time you refocus.
The good news is that focus can be trained. Here are five simple habits. (37) __________ Keep your phone in another room while you study. Out of sight is out of mind.
(38) __________ Work with full attention for 25 minutes, then rest for 5. Short, repeated blocks feel lighter than one long, tiring sit.
Get your body moving. (39) __________ A ten-minute walk between blocks resets your attention better than more screen time.
Last but not least, guard your sleep. (40) __________ Without enough rest, even the best methods lose their power. Focus is not only about willpower. It is about shaping your surroundings so attention comes naturally.
A. A short walk does the trick.
B. In reality, true multitasking does not exist.
C. Begin by clearing away distractions.
D. Try the "25-5" rhythm.
E. Sleep builds the base of all attention.
F. Drink water often to stay fresh.
G. Check messages only at fixed times.
答案：36–40 B C D A E
36. 前句 "Science says otherwise" 指科学不支持多任务，B 项 "真正意义上多任务并不存在" 承上启下。37. 本段讲把手机放到另一个房间，C 项 "先从清除干扰开始" 总领该条。38. 后文 "25 minutes" 和 "5-minute break" 直接对应 D 项的 "25-5 rhythm"。39. 本段讲动起来，后句 "ten-minute walk" 对应 A 项。40. 本段讲睡眠，后句 "Without enough rest" 对应 E 项。
