A级　阅读提升练 Ⅰ.阅读理解 A (2025·湖北武汉模拟)A bestseller by Giulia Enders explores the fascinating world of the human digestive system and its profound impact on overall health. One of the key takeaways is the idea that the gut(肠)is not just a digestion machine, but a complex and intelligent organ that influences our immune system, brain function, and emotional well­being. The book explores the gut­brain connection, explaining how the gut communicates with the brain and can influence mood and behavior, highlighting the link between gut health and mental conditions like anxiety and depression. Enders also explains how the gut's nervous system functions independently of the brain and why it's often called the “second brain”． Another key point is the impact of diet on gut health. Enders advises incorporating fiber­rich foods, fermented products(like yogurt), and probiotics(good bacteria)into our diet to nourish beneficial gut bacteria. She also warns against the overuse of antibiotics (抗生素), which can upset the balance of gut bacteria and lead to digestive disorders. The book also provides insight into common digestive problems and breaks down how these issues can be managed or prevented by making simple lifestyle changes, like eating slowly and managing stress. Enders explains the digestive process in a simple and engaging way, highlighting the importance of a healthy gut and offers practical advice on supporting its function, such as avoiding overly processed foods and eating mindfully. Enders also touches on the significance of the immune system in the gut, where a large portion of immune cells reside. A healthy gut microbiome (肠道微生物组)can strengthen the immune response, while an imbalanced gut may lead to increased risk to infections and autoimmune diseases. Enders successfully makes the science of the gut accessible and relatable, showing that by understanding how this often­overlooked organ works, we can make informed choices that significantly improve our health and happiness. [语篇解读]　这是一篇说明文。文章介绍了Giulia Enders的畅销书，探讨了人类消化系统的迷人世界及其对整体健康的深远影响。 1．What does the underlined word “takeaways” in paragraph 1 mean? A．Differences. B．Conclusions. C．Causes. D．Goals. 解析　B　词义猜测题。根据画线词出现的语境“the idea that the gut(肠)is not just a digestion machine, but a complex and intelligent organ that influences our immune system, brain function, and emotional well­being(肠道不仅仅是一个消化机器，而是一个复杂而智能的器官，影响我们的免疫系统、大脑功能和情绪健康)”以及第二段“The book explores the gut­brain connection, explaining how the gut communicates with the brain and can influence mood and behavior, highlighting the link between gut health and mental conditions like anxiety and depression. (这本书探讨了肠道与大脑的联系，解释了肠道如何与大脑沟通并影响情绪和行为，强调了肠道健康与焦虑和抑郁等精神疾病之间的联系。)”和第三段开头“Another key point is the impact of diet on gut health. (另一个关键点是饮食对肠道健康的影响。)”可知，这些都是这本书中的结论句，所以猜测 takeaways是指对文章要点“结论”。故选B。 2．What does the author might agree with? A．An unhealthy gut will definitely lead to immune disorders. B．The gut's nervous system interrelates with the brain in its function. C．Eating slowly or managing stress helps avoid some digestive problems. D．The more fiber we include in our diet, the healthier our gut will become. 解析　C　细节理解题。根据第四段“The book also provides insight into common digestive problems and breaks down how these issues can be managed or prevented by making simple lifestyle changes, like eating slowly and managing stress. (这本书还提供了对常见消化问题的见解，并剖析了这些问题，如何通过简单的生活方式改变来管理或预防这些问题，比如慢慢吃和管理压力。)”内容可知，通过改变一些生活习惯比如吃慢一点或者管理好压力有利于防止一些消化问题的出现。故选C。 3．Which one can best serve as the title of the book by Giulia Enders? A．Gut Health Is Above Wealth. B．Eat Your Way to Good Health. C．Immune System: A Deciding Factor in Overall Health. D．Gut: The Inside Story of Our Body's Most Underrated Organ. 解析　D　推理判断题。根据文章第一段“A bestseller by Giulia Enders explores the fascinating world of the human digestive system and its profound impact on overall health. One of the key takeaways is the idea that the gut (肠) is not just a digestion machine, but a complex and intelligent organ that influences our immune system, brain function, and emotional well­being.(Giulia Enders的畅销书探讨了人类消化系统的迷人世界及其对整体健康的深远影响。其中一个关键要点是，肠道不仅仅是一个消化机器，而是一个复杂而智能的器官，影响我们的免疫系统、大脑功能和情绪健康。)”以及下文可知，文章主要是讲了肠道在人体的重要功能和对其他方面健康的意义， 它并不是人们通常认为的只是一个消化食物器官， 它有着复杂而智能的神经系统， 且对人整体健康影响很大。所以D项Gut: The Inside Story of Our Body's Most Underrated Organ.(肠道：我们身体最被低估的器官的内幕。)符合语境，最可能是Giulia Enders的畅销书的书名。故选D。 4．What is the text? A．A book review. B．A research paper. C．An advertisement for a book. D．A chapter of a book. 解析　A　推理判断题。通过第一段内容“A bestseller by Giulia Enders explores the fascinating world of the human digestive system and its profound impact on overall health. (Giulia Enders的畅销书探讨了人类消化系统的迷人世界及其对整体健康的深远影响。)”和文章每一段的开头“The book explores (这本书探索)”类似表达和文章整体内容可以看出来，文章是对一本书进行介绍和评论，即这是一篇书评。故选A。 B (2025·全国名校联考)In higher education, where meritocracy (任人唯贤) and objectivity are highly valued, one might assume that the alphabetical order of students' surnames plays no role in determining their academic success. However, recent research suggests otherwise. A study conducted by researchers at the University of Michigan, analyzing over 30 million grading records, reveals a surprising finding: students with surnames that appear earlier in the alphabet tend to receive higher grades compared to their counterparts with later alphabetical placements. This bias is particularly striking in large classes or courses where assignments are submitted digitally through platforms like Canvas, a widely used online learning management system. Systems like this typically arrange student submissions alphabetically by default (系统默认). As a result, students with surnames towards the end of the alphabet, such as those starting with Y or Z, tend to receive lower grades on average compared to their peers with surnames from the beginning of the alphabet. This phenomenon is attributed to an effect known as “sequential grading bias”， which refers to an unintentional advantage or disadvantage that students may face due to the order in which their work is evaluated. For example, job interview candidates who are interviewed later in the day may be rated more harshly compared to those who went earlier. In the context of alphabetical ordering, instructors often begin grading from the top of the list, where surnames starting with letters like A or B appear. This initial advantage can unintentionally influence grading patterns, where early papers might receive more favorable assessments compared to those evaluated later. However, the exams that are graded in the reverse order in which they are submitted may show an opposite trend. Educational institutions and policymakers are encouraged to explore alternative grading strategies that mitigate alphabetical biases. Suggestions include randomized grading orders, nameless submissions, or deliberate efforts to counteract first impressions through diverse evaluation criteria. By addressing these biases proactively, institutions can foster fairer and more inclusive learning environments where student performance is evaluated impartially based on merit rather than surname placement. [语篇解读]　这是一篇说明文。文章介绍了一项研究发现：与按字母顺序排列较晚的学生相比，姓氏在字母表中出现较早的学生往往获得更高的成绩。 5．Why does the author mention Canvas in the context of the study? A．To promote the use of digital platforms for academic purposes. B．To highlight the popularity of online learning management systems. C．To emphasize the impact of digital learning platforms on grading biases. D．To demonstrate the diverse grading standards of digital learning platforms. 解析　C　推理判断题。由文章第二段“This bias is particularly striking in large classes or courses where assignments are submitted digitally through platforms like Canvas, a widely used online learning management system. Systems like this typically arrange student submissions alphabetically by default (系统默认). As a result, students with surnames towards the end of the alphabet, such as those starting with Y or Z, tend to receive lower grades on average (这种偏见在通过Canvas等广泛使用的在线学习管理系统以数字方式提交作业的大班或课程中尤为明显。默认情况下，这样的系统通常按字母顺序排列学生提交的内容。因此，姓氏在字母表末尾的学生，如以Y或Z开头的学生，平均成绩往往较低)”可知，作者在研究中提到了Canvas，以强调数字学习平台对评分偏差的影响。故选C。 6．In the last paragraph, what does the underlined word “mitigate” mean? A．Complicate. B．Simplify. C．Fuel. D．Reduce. 解析　D　词义猜测题。由最后一段“Educational institutions and policymakers are encouraged to explore alternative grading strategies that mitigate alphabetical biases.(鼓励教育机构和政策制定者探索字母偏差的替代评分策略。)”以及上文可知，现在在线学习管理系统存在评分偏差问题，所以这里希望有新的平台可以“减少”这种字母偏差。所以猜测mitigate表示“减少”的意思。故选D。 7．According to the text, one suggested alternative grading strategy should be based on ． A．the student's surname B．random grading sequence C．random first impression D．the student's submission time 解析　B　细节理解题。由文章最后一段“Suggestions include randomized grading orders, nameless submissions, or deliberate efforts to counteract first impressions through diverse evaluation criteria. (建议包括随机评分顺序、匿名提交或通过不同的评估标准刻意抵消第一印象。)”可知，一种对现在评分策略替代的建议是按照随机序列评分。故选B。 8．Which of the following may be the best title for this passage? A．Inequality Issues via Digital Learning Systems B．Strategies for Overcoming Bias in Grading Systems C．Unintended Consequences of Alphabetical Grading D．The Cause of Sequential Grading on Student Performance 解析　C　标题归纳题。由第二段“A study conducted by researchers at the University of Michigan, analyzing over 30 million grading records, reveals a surprising finding: students with surnames that appear earlier in the alphabet tend to receive higher grades compared to their counterparts with later alphabetical placements. (密歇根大学的研究人员进行的一项研究分析了3000多万条评分记录，揭示了一个令人惊讶的发现：与按字母顺序排列较晚的学生相比，姓氏在字母表中出现较早的学生往往获得更高的成绩。)”以及上下文可知，文章主要讲研究人员惊讶地发现与按字母顺序排列较晚的学生相比，姓氏在字母表中出现较早的学生往往获得更高的成绩。所以C项Unintended Consequences of Alphabetical Grading(按字母顺序评分的意外结果)适合作文章标题。故选C。 Ⅱ.七选五 (2024·山东济南质检)The brain is often seen as the most important organ of us humans. It controls our thoughts, emotions, memories and even our movements. However, what many people often forget is that the brain and the body are closely connected. 1 Studies have shown that regular exercise can significantly improve cognitive functions such as memory, attention and problem­solving abilities. 2 How does this happen? Well, the answer lies in the way exercise affects the brain. Exercise increases the production of proteins that promote the growth and survival of neurons (神经元)，thus ensuring better brain functions. Moreover, exercise has a positive impact on moods and mental well­being. It helps release some natural mood boosters that make us feel more positive and happy. 3 As for the exercise variety, it's not just about aerobic (有氧的) exercise like running or cycling. 4 It improves concentration and decision­making abilities by enhancing the connectivity between different regions of the brain. 5 Exercise isn't just about keeping fit or losing weight; it's about improving cognitive functions, boosting moods and even helping us think more creatively. So, the next time you feel lazy or unmotivated to exercise, remember that every step you take is one step closer to a healthier, happier and more intelligent you. A．It even strengthens creativity. B．Actually the body deeply affects the brain. C．The brain also has great impacts on exercise. D．An exercise lover is unlikely to suffer from depression. E．Walking and jogging do good to mental functions too. F．Strength training has also been shown to benefit the brain. G．The links between the brain and the body cannot be overstated. [语篇解读]　本文是一篇说明文。大脑通常被视为人类最重要的器官。它控制着我们的思想、情绪、记忆，甚至我们的行动。然而，大脑和身体是紧密相连的。研究表明，经常锻炼可以显著提高记忆力、注意力和解决问题的能力等认知功能。 1．解析　B　空前讲“然而，许多人经常忘记的是，大脑和身体是紧密相连的。”；下文提到“经常锻炼可以显著提高记忆力、注意力和解决问题的能力等认知功能”，揭示了身体对大脑的影响，故B项“事实上，身体深深地影响着大脑”承上启下，符合语境。故选B。 2．解析　A　空前提到“研究表明，经常锻炼可以显著提高记忆力、注意力和解决问题的能力等认知功能。”，A项“它甚至增强创造力”与上文内容构成递进关系，均描述了经常锻炼对大脑的影响。A项中的It指代空前的“regular exercise”。故选A。 3．解析　D　空前的“exercise has a positive impact...feel more positive and happy”讲锻炼对情绪和精神健康有积极的影响。它有助于释放一些自然的情绪舒畅剂，让我们感觉更积极和快乐。D项“一个运动爱好者不太可能患抑郁症”承接上文，符合语境。故选D。 4．解析　F　根据空前的“至于运动种类，不仅仅包括像跑步或骑自行车这样的有氧运动。”，并结合常识可推知，空处内容应与无氧运动有关。故F项“力量训练也被证明对大脑有益”承接上文。空后的It指代F项中的“Strength training”。故选F。 5．解析　G　空处所在段是文章的总结段。上文具体描述了锻炼是如何积极地影响大脑的。下文讲“锻炼不仅仅是为了保持健康或减肥；它也可以提高认知功能，提升情绪，甚至帮助我们更具创造性地思考。”，再次强调了锻炼对大脑的积极影响。故G项“大脑和身体之间的联系再怎么夸大都不为过”符合语境。故选G。 Ⅲ.完形填空 (2025·湖南长沙质量检测)Hearing the Olympics were coming to Vancouver, I decided to go for its voluntary work.

As with most large cities, the homeless population in my city often gathered on downtown corners, asking pedestrians for their spare change. Like many busy citizens, I had learned to ignore the nameless faces begging for money each day. My limited life experience had led me to one assumption—they were on the streets because they chose to be, probably due to alcohol or other similar things. But who would have thought that the first person to change the way I viewed humanity would be a completely stranger? My overall outlook on people took a 180­degree turn in less than ten minutes. I remember how particularly cold the weather had been that day. I saw one man sitting against a building, holding a white cup in front of him. His shaky voice reached out to me as I hurried past. “Spare some change？” he asked. “I would really appreciate it.” I didn't even bother looking up at his nameless face. “Sorry, no money on me today，” I made a lie as usual quickly, my eyes fixed on the ground ahead. Just a few feet past him, I slipped on the icy pavement and fell hard. I lay there for several moments, stunned and wondering if I had broken my leg. “Are you all right？” A voice came from above me. I looked up and it was the man I had just rushed past, concern written on his face. He reached down, trying to offer help. “You should get that checked by a doctor. This bus goes past the hospital，” he said, pointing to the bus sign above me. I held his hand as I struggled to get to my feet. He held my arm as I hobbled to the nearby bus stop and quickly sat on the bench. A mix of emotions swelled within me—gratitude for his help, embarrassment for my earlier ignorance, and anxiety about getting to work on time. For a moment, I met his gaze, unsure of what to say. Then, a sudden realization crossed his face. 注意：1.续写词数应为150左右； 2．请按如下格式在相应位置作答。 “Ah, I forgot you didn't have any money on you，” he said. Seeing the bus approaching, I quickly took several bills out of my purse. One possible version： “Ah, I forgot you didn't have any money on you，” he said. Almost immediately, I watched as he fished out some coins from his white cup, his eyes brimming with care and sincerity. I was overwhelmed with guilt as I remembered the lie I had just told him only a few short minutes earlier. The coins shone like diamonds of humanity among the concrete jungle of the city and a mirror that reflected my selflessness and ignorance. “Sorry, actually，” I said, finding my voice, “I do have money.” I turned away from his offering hand, reached for my purse, and pulled it out. Seeing the bus approaching, I quickly took several bills out of my purse. I offered the bills to him with genuine respect and humility. The words tasted bitter as I admitted my dishonesty. His eyes widened slightly, but he didn't look angry. I could feel he was hesitating, and just then, the bus approached. I pressed the money into his hands. “I appreciate your help, more than you know. Please do take this，” I said sincerely. He helped me to stand up and said “Thank you”， the simplest words that humbled me like never before. With a final nod, I limped towards the bus stop. Despite his gratitude, I didn't feel forgiven for my actions. These bills seemed too small a gift for the man who gave a name to every nameless face. 学科网（北京）股份有限公司 $$
