Wearables are playing an increasing role in managing and detecting conditions like atrial fibrillation (心房颤动)，the most common heart rhythm problem.For many people，the sense that they are receiving reliable，objective and personalized health data can encourage feelings of confidence，safety and assurance.This may allow patients to self-manage their condition at home with their families，rather than spending time in hospital—reducing anxiety and stress.In a clinical setting，data may also encourage patients to take part in shared decision-making.Interpreting health data together with doctors or other health-care professionals，they can develop goals and action plans，including when to seek help，and when to go to hospital.Patients who understand their condition tend to report fewer atrial fibrillation symptoms. However，a study examined the behavior and well-being of 172 people with atrial fibrillation over a nine-month period.It found the 83 people who used wearables to monitor their condition were more worried about their symptoms and treatment，with one in five experiencing “intense anxiety”．Chronic anxiety can contribute to stress，burnout and poor physical health，which in turn can exacerbate (加剧) heart conditions. Some people also describe being a “prisoner of the numbers”．They feel they “need to keep checking the device to know how they were doing，leading to the device dominating their lives”．The volume and frequency of notifications (通知)，alarms and vibrations from wearable devices can be overwhelming and make people worry about their health.Information overload can also discourage self-management，with notifications instead prompting people to seek health advice more often than they otherwise would. It's _a_catch­22_situation:_The wearable device may help you better manage your chronic heart condition，but wearing it could make you anxious—which is bad for those conditions. [语篇解读]　本文是一篇说明文。文章主要介绍了可穿戴设备(如智能手表)对病人的影响——既可能提升健康管理能力，又可能引发焦虑。 1．What is the main idea of the second paragraph? A．Usage of personalized health data. B．Benefits of wearing wearables. C．How to manage health condition at home. D．When to seek medical attention. 解析　段落大意题。第二段首句指出可穿戴设备在管理和检测心房颤动等病症方面正发挥着越来越重要的作用。接着说明它们能帮助患者在家自我管理病情，减少住院需求。然后提到在临床环境中，数据能促进医患共同决策。最后强调了解病情的患者症状更少。综上，第二段主要说明了可穿戴设备的益处。故选B。 答案　B 2．What can we infer from the study? A．About 89 people were healthy. B．Wearables monitor people's condition accurately. C．About 35 people experienced intense anxiety. D．Wearables can make people's condition worse. 解析　推理判断题。根据第三段中的“Chronic anxiety can contribute to stress，burnout and poor physical health，which in turn can exacerbate heart conditions.”可知，使用可穿戴设备可能导致紧张、疲倦和身体健康不佳，进而加剧心脏疾病。由此可推知，可穿戴设备可能会使人们的病情恶化。故选D。 答案　D 3．What does the underlined phrase “a catch-22 situation” in paragraph 5 mean? A．A dilemma. B．A reality. C．A category. D．A phenomenon. 解析　词义猜测题。冒号后的内容是对画线短语的解释。根据“The wearable device may help you better manage your chronic heart condition，but wearing it could make you anxious—which is bad for those conditions.”可知，可穿戴设备既可能有助于更好地管理慢性心脏病，又可能让人焦虑，从而对病情有害。由此可以看出，这是一个进退两难的局面。故选A。 答案　A 4．What might be a suitable title for the text? A．Digital Devices Are Irreplaceable in Life B．Being Monitored Is Good for Our Health C．Wearables Are a Two-Sided Coin D．Wearables Lead People to Be More Anxious 解析　标题归纳题。文章首段为背景介绍，指出可穿戴的追踪器和检测设备的普及趋势。中间三段说明了可穿戴设备的积极影响和消极影响。最后一段用a catch-22 situation形象地总结出可穿戴设备是一把双刃剑。C项形象地表达出可穿戴设备既有利又有弊的特点。故选C。 答案　C B (2025·浙江温州二模)In the risky world of nuclear arms control，Princeton student Lepowsky is exploring how robots can make inspections more accurate and acceptable to host nations worried about invasive (侵入的)traditional methods.His latest research has led to a robot performing inspections without saving sensitive information. “The host nation likely won't want a human inspector poking their nose around，” said Lepowsky.“But even a robot has memory and sensors acquiring data.” The goal is to have high-confidence inspections without the robot saving information.For example，the robot would not save radiation measurements or create floor plans of sensitive areas. The new prototype (样机) is built on an iRobot Create 3 platform，an educational robot.Robots offer advantages over human inspectors: they can tolerate higher radiation levels，are more consistent，and can be cheaper.They also can be programmed to generate trust，such as not using cameras to avoid seeing unwanted details.The idea for the robot started with Lepowsky's adviser，Glaser，who was curious about creating a “forgetful robot” that could perform highly accurate nuclear arms inspections but forget everything afterward.This led to an even more interesting idea.“Rather than forgetting，we're not even remembering in the first place，” Lepowsky said.He believes this feature can reassure hosts concerned about privacy. Lepowsky likes the interdisciplinary nature of his work—drawing on both his robotics and policy expertise—and he likes that it requires a breadth of knowledge，not just depth.He values that his research is grounded in real-life applications for global security and nuclear nonproliferation (防扩散). Predicting when the robot might be used in the field is difficult.“It's easy to say，today，it's not very realistic，but you have to be ready for if and when it becomes possible，” said Lepowsky.Research into this problem is very active.Because arms control is changing，the specific objectives of future agreements are hard to predict.“But we can hope they will be positive，and we need to be ready，technically，” he said. [语篇解读]　本文是一篇说明文。文章介绍了普林斯顿大学学生Lepowsky研发的一款用于核武器核查的“无记忆机器人”。 5．In which aspect is Lepowsky's robot different from human inspectors? A．Data security. B．Memory capacity. C．Social acceptance. D．User friendliness. 解析　细节理解题。题干询问Lepowsky的机器人与人类检查员在哪个方面不同。第二段提到人类检查员可能会四处探查(poking their nose around)，而他的机器人不保存辐射测量数据，也不绘制敏感区域平面图(would not save radiation measurements or create floor plans of sensitive areas)。由此可知，人类检查员可能记录敏感信息，而机器人不存储数据。因此，机器人在数据安全性(Data security)上优于人类。故选A。 答案　A 6．What is said about the robot in paragraph 3? A．Its accurate system. B．Its privacy risks. C．Its design mechanism. D．Its operational problems. 解析　段落大意题。第三段主要介绍了机器人的建造平台、优势以及创意来源。由此可以看出，第三段主要围绕机器人的设计机制展开。故选C。 答案　C 7．What does Lepowsky like about his work? A．Scientific research data. B．Real-time technical cooperation. C．In-depth theoretical studies. D．Integrated knowledge across fields. 解析　细节理解题。根据第四段首句“Lepowsky likes the interdisciplinary nature of his work—drawing on both his robotics and policy expertise—and he likes that it requires a breadth of knowledge，not just depth.”可知，Lepowsky喜欢工作的跨学科性，也喜欢它对知识广度的要求。D项(跨领域的综合知识)是对原文的综合概括。故选D。 答案　D 8．Which would be the best title for this passage? A．Princeton's “Forgetful” Robots in Global Security B．No-Memory Robots: The Future of Nuclear Checks? C．Nuclear Arms Control: Robots or Human Inspectors? D．Lepowsky's “Curious” Robots for Radiation Detection 解析　标题归纳题。文章首先提出了核武器检查中，传统的人类检查方式可能有信息安全问题，然后介绍了Lepowsky研发的“无记忆机器人”，通过不存储数据解决信息安全问题。B项(无记忆机器人：核检查的未来？)包含了“机器人”“核检查”两大关键要素，并突出了“无记忆”的特点，因此为最佳标题。 答案　B C (2025·江苏南京、盐城模拟)Imagine an artificial intelligence model that can watch and understand moving images like you and me.Now，scientists have made this a reality by creating MovieNet: an innovative AI model that processes videos much like how our brains interpret real-life scenes. This brain-inspired AI model can perceive moving scenes by simulating how neurons (神经元) make real-time sense of the world.While conventional AI excels at still image recognition，MovieNet is designed to understand complex，dynamic scenes，allowing it to recognize small changes over time. To create MovieNet，Hollis Cline，senior author of the study，examined how animals' brains process real-world scenes.Specifically，she studied how tadpoles' (蝌蚪的) neurons respond to moving stimuli.Tadpoles' neurons process these visual inputs like solving puzzle pieces: each piece alone may not make sense，but together they form a complete image in motion.Different neurons process various “puzzle pieces” of a real-life moving image，which the brain then combines to form a continuous scene. Using this understanding，the researchers trained MovieNet to process video clips by identifying small visual signals，allowing it to distinguish between small changes in scenes.In testing，MovieNet achieved 82.3% accuracy，outperforming trained human observers by about 18% and doing much better than existing AI models. Beyond its higher accuracy，MovieNet is more environment-friendly.Conventional AI requires vast amounts of data and energy，but MovieNet compresses (压缩) data like a zipped file，reducing environmental impact.“We've also made AI far less demanding，” says Cline.MovieNet could also transform medicine.It might help detect early signs of diseases by tracking small movement changes that are difficult for human eyes to detect. Looking ahead，the team plans to improve MovieNet's ability to adapt to different environments and enhance its potential applications.“By designing models that think like living organisms (有机体)，we can achieve efficiency levels that aren't possible with traditional AI，” says Cline.“Biology is a gold mine.” [语篇解读]　本文是一篇说明文。科学家研发出新型人工智能模型 MovieNet，它通过模拟神经元如何实时感知世界来理解动态场景。研究人员借研究蝌蚪神经元训练该模型通过识别微小的视觉信号来处理视频片段。测试中，MovieNet 准确率高，远超人类观察者和现有的人工智能模型，此外，MovieNet 更环保，未来有望在更多领域应用。 9．What does the underlined word “simulating” mean in paragraph 2? A．Copying. B．Inspiring. C．Demonstrating. D．Recognizing. 解析　词义猜测题。根据第一段的 “MovieNet：an innovative AI model that processes videos much like how our brains interpret real-life scenes”可知，MovieNet 是一款新型人工智能模型，其处理视频的方式与人类大脑解读现实生活场景的方式极为相似。再结合画线词所在句可推知，MovieNet这一人工智能模型受大脑启发而研发，它通过模拟大脑中的神经元如何实时感知世界来理解动态场景，故画线词的含义与A项“模仿，仿效”的意思最为接近。 答案　A 10．MovieNet is trained________． A．to integrate dynamic images B．to increase visual inputs C．to feed on information pieces D．to look into tadpoles' neurons 解析　推理判断题。第三段讲为了创造 MovieNet，研究人员研究了动物大脑是如何处理现实世界场景的，具体来说，就是研究蝌蚪的神经元如何对移动刺激作出反应。研究人员发现，蝌蚪的神经元处理这些视觉输入的方式就像在拼拼图，不同的神经元处理现实生活中动态图像的各种“拼图碎片”，然后大脑将这些碎片组合起来，形成一个连续的场景。再根据第四段首句 “Using this understanding，the researchers trained MovieNet to process video clips by identifying small visual signals，allowing it to distinguish between small changes in scenes.”可知，基于对蝌蚪大脑处理现实世界场景的方式的理解，研究人员训练MovieNet通过识别微小的视觉信号来处理视频片段，使其能够区分场景中的细微变化。由此可知，研究人员训练MovieNet整合动态图像。选项中的integrate对应文中的process，dynamics images 对应文中的video clips。 答案　A 11．According to paragraph 5，what is an advantage of MovieNet? A．Its powerful data storage. B．Its low energy consumption. C．Its control of medical diseases. D．Its improvement on drug effects. 解析　细节理解题。根据第五段的“MovieNet is more environment-friendly...reducing environmental impact ” 可知，MovieNet 更加环保，相对于传统的人工智能需要大量的数据和能源而言，它能像压缩文件一样压缩数据，从而减少对环境的影响，即能源消耗低。 答案　B 12．What can be concluded from Cline's words in the last paragraph? A．Biology brings us financial profits. B．Living organisms can outperform AI. C．AI can assist in biological development. D．Drawing inspiration from biology is promising. 解析　推理判断题。最后一段Cline说，通过设计像生物体一样思考的模型，人们能够达到传统人工智能无法实现的效率水平，生物学是一座金矿。这表明从生物学中获取灵感来设计人工智能模型是很有前景的。 答案　D Ⅱ.七选五 (2025·山东潍坊模拟)Online shopping often involves endless options and dizzying discounts.A single search for running shoes can produce hundreds of results.__13__ What if there is a tool capable of hunting for the best prices and making sure your purchases arrive on time?
