作业(九) (限时：40分钟) 说明：阅读理解每题2.5分，完形填空每题1分，语法填空每题1.5分，本试卷共50分。 Ⅰ.阅读理解 A (2026·辽宁大连一模)Have you ever interrupted an important occasion to send a text? Does the mere thought of being cut off from all technology make you panic? Is your ideal six­month break an extended period playing a video game in a windowless bedroom? If so, visit Capio Nightingale Hospital, a technology­addiction centre. “If teenagers spend a lot of time on their own, they run the risk of being developmentally out of step with others of their age group，” says Capio Nightingale's senior specialist Dr Richard Graham.“It's a very young field of research, but there's some evidence to suggest that teenagers who spend too much time on social media miss out on key developmental steps.They could feel immature.Extreme cases can end up putting people's education and employment at risk.Then there are the physical aspects.They can have a poor diet, lose weight, or not take care of themselves properly.” Teenagers, necessarily, are a high­risk group, as are those who have had a separation or who have been laid off.But no one is free from its impact.Technology experts tell the story of the young Texan boy who developed repetitive strain disorder from testing, or the couple who were building a “virtual baby” on the Internet but forgot to look after their real­life child.Scientists believe that handling phone calls, email and other incoming messages all at the same time can change how we think or behave. “At the moment researchers are trying to study the effects of high use of technology during the early parts of people's lives，” continues Graham.“There are some key points when permanent connections are made inside the brain.For example, if you have a minor eyesight problem and it is not remedied in the first five years of your life, part of the area of your brain responsible for processing visual information switches off.It's a ‘use it or lose it’ principle and it might be relevant to teenage technology addiction.” [语篇解读]　这是一篇说明文。文章主要探讨了科技成瘾对青少年的身心影响及其潜在危害，并引用专家观点和案例说明这一问题的严重性。 1．What does Graham think of technology addiction? A．It has long been studied by researchers. B．It may result in teenagers' extreme views. C．It affects teenagers mentally and physically. D．It slows the physical development of teenagers. 解析　细节理解题。根据第二段可知，科技成瘾影响青少年的精神和身体。故选C。 答案　C 2．Why does the author mention the Texan boy and the couple in paragraph 3? A．To clarify a statement. B．To explain a rule. C．To introduce a new topic. D．To make a prediction. 解析　推理判断题。根据第三段可推知，文章提到德克萨斯男孩因测试游戏患上重复性劳损症，以及夫妇沉迷虚拟婴儿而忽视现实孩子，是为了例证前文观点“no one is free from its impact(无人能免受科技影)”。故选A。 答案　A 3．What does the underlined word “remedied” in the last paragraph mean? A．Ignored. B．Detected. C．Worsened. D．Treated. 解析　词义猜测题。根据画线词所在句“if you have a minor eyesight problem and it is not remedied in the first five years of your life, part of the area of your brain responsible for processing visual information switches off.”可知，如果有轻微的视力问题，且在生命的前五年没有得到“治疗”，大脑中负责处理视觉信息的部分区域就会关闭，所以“remedied”意为“治疗”。故选D。 答案　D 4．What can be a suitable title for the text? A．Technology：a new burden for people B．The rise of technology­addiction centers C．Technology addiction：a problem worth noticing D．How to overcome negative effects of technology 解析　标题归纳题。通读全文尤其第二段可知，文章主要探讨了科技成瘾对青少年的身心影响及其潜在危害，并引用专家观点和案例说明这一问题的严重性。由此可知，“科技成瘾：一个值得注意的问题”最适合作本文标题。故选C。 答案　C B (2025·八省联考)Want to learn a new language or get A's in college exams? Previous studies have shown that exercise can help stimulate the areas of the brain that convert (转换) new information into long­term memory. A new study has taken this information one step further and found the best time when exercise can help maximize learning. Building upon past research that found exercise releases biochemicals that improve mental function, scientists at Radboud University and the University of Edinburgh conducted a study to determine when exercise was most beneficial to learning. Participants—72 healthy male and female adults—were first asked to perform a computer test that challenged their visual and spatial learning. After the test, all of the subjects watched nature documentaries, but two­thirds of them also exercised. Half of the exercisers did circuit training on an exercise bike for 35 minutes immediately after the test. The other half did the same exercise but not until four hours after they had been tested. Two days later, all of the participants returned to the lab for a recall test, and they were connected to MRI (磁共振成像) machines to assess their brain activity. The participants who exercised four hours after taking the computer test were able to recall what they had learned most accurately. Their brainwaves also showed more consistent levels of activity, indicating that their brains were less taxed to remember what they had learned. According to this research, the best time to exercise to improve learning is four hours after studying. But why? That's one question the researchers have yet to answer. Another question left unanswered is the level of exercise that might best improve learning. I've run enough marathons to prove the fact that my brain is anything but sharp during or after a tough workout. But the researchers noted that light workouts might not give the brain enough of a biochemical boost to improve learning. [语篇解读]　这是一篇说明文。文章主要介绍了一项新研究——锻炼可以帮助刺激大脑将新信息转化为长期记忆，以及可以有助于最大化提高学习效果的最佳时间。 5．What did the new study aim to explore? A．When exercise is best for learning. B．What biochemicals are good for health. C．How brainwaves should be measured. D．Which area of the brain is the most active. 解析　细节理解题。根据第一段中“A new study has taken this information one step further and found the best time when exercise can help maximize learning.(一项新的研究更进一步找到了锻炼有助于最大化学习效果的最佳时间。)”可知，新研究旨在探索什么时候锻炼最有利于学习。故选A。 答案　A 6．What were all the participants asked to do during the experiment? A．Train on bicycles. B．Do mathematics exercises. C．Play computer games. D．Watch films about nature. 解析　细节理解题。根据第三段中“After the test, all of the subjects watched nature documentaries(测试后，所有受试者都观看了自然纪录片)”可知，实验要求所有受试者在实验过程中观看自然纪录片。故选D。 答案　D 7．Why did the participants return to the lab two days later? A．To do a medical examination. B．To have their memory tested. C．To get their workouts recorded. D．To finish their previous tasks. 解析　细节理解题。根据第四段中“Two days later, all of the participants returned to the lab for a recall test(两天后，所有参与者返回实验室进行回忆测试)”可知，参与者两天后返回实验室是为了进行记忆测试。故选B。 答案　B 8．What might the author's marathon running prove? A．The findings of the study are reliable. B．Long­distance runners are often smart. C．Studies on the marathon are not enough. D．Hard exercise may not sharpen the brain. 解析　推理判断题。根据最后一段中“I've run enough marathons to prove the fact that my brain is anything but sharp during or after a tough workout.(我已经跑了足够多的马拉松来证明这样一个事实：在艰苦的锻炼过程中或之后，我的大脑一点也不敏锐。)”可知，作者通过自己跑马拉松的经历证明，剧烈的锻炼可能不会使大脑变得敏锐。故选D。 答案　D Ⅱ.完形填空 (2025·安徽合肥联盟模拟)I started writing poetry just after hitting my teens.Then I quickly fell in love with the artistry, wordplay, and rhythmic challenge of 9 poems.
