His hands moved with effortless grace, shaping a beautiful bowl in seconds. 3 , I sat at my wheel, expecting similar results. Instead, disaster 4 . My clay flew off the wheel, leaving mud everywhere. When I finally managed to keep the clay on the wheel, my 5 to pull it upwards resulted in ruined masses. By the end of the second week, I was ready to quit. Seeing my 6 , the instructor walked over. “You’re 7 the clay,” he observed gently. “Stop trying to force it to be perfect. Just feel the material and let it take the shape it wants.” Taking a deep breath, I closed my eyes, 8 my strict expectations, and allowed my hands to move naturally. When I opened my eyes, the bowl wasn’t perfect, but it stood upright, 9 the unique marks of my fingers. I kept that imperfect bowl as a constant reminder that the beauty of a new skill lies in the messy 10 of learning, not just the final result. 1．A．base B．shelter C．stage D．cage 2．A．explained B．demonstrated C．imagined D．reviewed 3．A．Hesitantly B．Cautiously C．Confidently D．Nervously 4．A．struck B．returned C．continued D．passed 5．A．decisions B．intentions C．abilities D．attempts 6．A．frustration B．relief C．excitement D．guilt 7．A．wasting B．fighting C．blaming D．destroying 8．A．held on to B．lived up to C．let go of D．kept track of 9．A．removing B．leaving C．suffering D．bearing 10．A．standard B．process C．purpose D．method 【答案】 1．D 2．B 3．C 4．A 5．D 6．A 7．B 8．C 9．D 10．B 【导语】本文主要讲述了作者曾经认为自己是一个完美主义者，在30岁生日后决定尝试新事物——学习陶艺，在经历了一系列失败和挫折后，在指导老师的帮助下，最终领悟到学习新技能的美妙之处在于过程中的不完美体验。 【详解】1．考查名词。句意：但30岁的到来让我意识到我的舒适区已经变成了一个牢笼。A. base基础；B. shelter庇护所；C. stage阶段；D. cage牢笼。根据前文“If I couldn’t do something well from the start, I simply wouldn’t do it at all.”可知，作者一直待在舒适区里不敢尝试新事物，这种状态像“牢笼”一样束缚着她。 2．考查动词。句意：在第一节课上，老师演示了如何在转轮上定中心。A. explained解释；B. demonstrated演示；C. imagined想象；D. reviewed复习。根据后文“His hands moved with effortless grace, shaping a beautiful bowl in seconds.”可知，老师动手示范了制作过程，应用demonstrated。 3．考查副词。句意：我信心满满地坐在我的转轮前，期待着类似的结果。A.

Students will love exploring while also gaining invaluable experience by designing and conducting experiments. Sunscreen Experiment Kids often don’t enjoy being told they need sunscreen, so showing its power through demonstration can help them see its value. This science fair project uses simple white beads (珠子) that change color when exposed to UV rays (紫外线) so children can compare the effectiveness of different sunscreen products. Start this experiment by applying some of each sunscreen type on paper and placing both pieces of paper in direct sunlight for several hours. Sundial (日晷) Experiment Using a sundial to tell time is a fascinating science activity that helps students gain knowledge of shadows and the movement of sunlight across the sky. Through this hands-on experiment, students gain an opportunity to see how people in previous times knew time without clocks or watches. Start this experiment by asking students to identify an outdoor spot that receives sunlight all day, placing a flat board there, tracing the shadows onto it and noting where the shadows will fall at certain points of the day. Mineral Experiment Students learn to identify rocks and minerals through this simple experiment. They use a plate to test the hardness of various common minerals. They also observe how these minerals form crystals (晶体) and how they break apart differently from others. This lesson helps students understand the characteristics and uses of different minerals. Students can even form “companies” and compete to mine different types of rocks with specific features. 21．What is the main purpose of using beads in the sunscreen experiment? A．To compare the prices of sunscreen. B．To show the effectiveness of sunscreen. C．To analyze the impact of sunscreen on skin. D．To demonstrate chemical reactions in sunscreen. 22．How do students begin the sundial experiment? A．By building a sundial from beginning. B．By comparing different types of sundials. C．By measuring the length of their shadows. D．By identifying a sunny spot and using a flat board. 23．What does the mineral experiment allow students to do? A．Observe crystal formation. B．Learn geological history. C．Sell rocks they mine. D．Form companies. 【答案】21．B 22．D 23．A 【导语】本文是应用文。文章介绍了几个适合学生做的科学实验。 【详解】21．细节理解题。根据Sunscreen Experiment下的“This science fair project uses simple white beads (珠子) that change color when exposed to UV rays (紫外线) so children can compare the effectiveness of different sunscreen products.(这个科学展览项目使用简单的白色珠子，当暴露在紫外线下时会改变颜色，这样孩子们就可以比较不同防晒产品的效果)”可知，在防晒实验中使用珠子的主要目的是来展示防晒霜的功效。故选B项。 22．细节理解题。根据Sundial (日晷) Experiment下的“Start this experiment by asking students to identify an outdoor spot that receives sunlight all day, placing a flat board there, tracing the shadows onto it and noting where the shadows will fall at certain points of the day.(实验开始时，让学生们找出一个整天都能接受阳光的户外地点，在那里放一块平板，在上面画出阴影，并注意到阴影在一天中的特定时间会落在哪里)”可知，学生找一个阳光充足的地方，用一块平板来开始日晷实验。故选D项。 23．细节理解题。根据Mineral Experiment下的“They also observe how these minerals form crystals (晶体) and how they break apart differently from others.(他们还观察这些矿物质是如何形成晶体的，以及它们是如何以不同的方式分裂的)”可知，Mineral Experiment允许学生观察晶体形成。故选A项。 B As we grow up, it becomes natural for us to lose contact with the hobbies that once were important in our lives. While it’s painful to accept this, the new reality becomes normal for most of us as we face new academic, adult and job responsibilities. I’ve been dancing since I was four and I plan to continue dancing in college. However, I’ve always feared that dancing will affect my study and eventually become a happy memory of my childhood. After learning about Sommer Gentry’s story, I had an answer. Sommer Gentry, previously a professor of mathematics at the United States Naval Academy and a coach at the Naval Academy’s Swing Dance Club, is currently a teacher at NYU Grossman School of Medicine. Gentry and her husband also started a swing dance community to introduce non-dancers to swing dance. Through teaching, Gentry was inspired to view dancing from an engineering point of view. She said, “I realized it is an engineering question: How do you dance well with someone? It’d be great to give people mathematical and engineering proofs that they have to dance the way I say.” Gentry investigated the complex haptic (触觉的) communication behind the moves in swing dance and showed that two persons could move in coordination (协调) with pure haptic communication. She entered an exciting area of research which is about engineering, psychology and human motor control. It’s incredibly inspiring that Gentry was able to intertwine her academic work with her love for dancing. Gentry said, “It means that even when I’m dancing outside, I’m thinking about my research project.” Gentry found that digging into her academic interest does not mean letting go of her other non-academic ones. Instead, she found a way to include both in her professional life. Just like me, Gentry is a mathematician and dancer, thus, her story resonates (引起共鸣) strongly with me, and I want to be like her in the future. 24．What did the author think of dancing before learning of Gentry’s story? A．It was too challenging for her. B．It might disappear from her life. C．It brought her pleasant memories. D．It developed her sense of responsibility. 25．According to the fourth paragraph, which of the following best summarizes the main idea? A．Gentry chose academics over dancing. B．Gentry gave up dancing due to its irrelevance to her research. C．Dancing has no connection to engineering or psychology for Gentry. D．Gentry viewed dancing as an engineering problem. 26．What does the underlined word in paragraph 5 probably mean? A．Hardly balance. B．Carefully compare. C．Closely combine. D．Successfully challenge. 27．What can we infer about the author from the last paragraph? A．She has decided to change her major. B．She will continue to pursue her hobby. C．She used to be Sommer Gentry’s student. D．She originally had little interest in engineering. 【答案】24．B 25．D 26．C 27．B 【导语】本文讲述了作者从小学习舞蹈，一直担心学业压力会让自己不得不放弃舞蹈爱好，在了解到数学家兼舞蹈爱好者Sommer Gentry将学术研究与舞蹈爱好紧密结合的故事后，作者找到了坚持爱好的方向。 【详解】24．细节理解题。根据第二段“However, I’ve always feared that dancing will affect my study and eventually become a happy memory of my childhood. (然而，我一直担心跳舞会影响我的学习，最终只成为我童年的一段美好回忆)”可知，作者之前一直担心跳舞会因为学业影响最终退出自己的生活，只成为童年回忆。 25．主旨大意题。根据第四段中“Through teaching, Gentry was inspired to view dancing from an engineering point of view.(在教学过程中，Gentry得到启发，从工程学的角度看待舞蹈)”、“I realized it is an engineering question(我意识到这是一个工程学问题)”、“She entered an exciting area of research which is about engineering, psychology and human motor control.(她进入了一个令人兴奋的研究领域，即工程学、心理学和人类运动控制。)”并结合整段内容可知，整段围绕Gentry从工程学视角研究舞蹈展开，研究舞蹈中的触觉沟通，并将舞蹈与工程、心理学、人类运动控制相结合。 26．词句猜测题。根据第五段划线词所在句“It’s incredibly inspiring that Gentry was able to intertwine her academic work with her love for dancing. (Gentry能够将她的学术工作和对舞蹈的热爱intertwine，这件事极具启发性)”并结合后文“It means that even when I’m dancing outside, I’m thinking about my research project.(这意味着即使我在外面跳舞，我也在思考我的研究项目)”以及下一段“she found a way to include both in her professional life(她找到了一种方法，将两者都融入到她的职业生活中)”可知，Gentry能够将她的学术工作与对舞蹈的热爱紧密结合起来，intertwine的含义是“紧密结合”。 27．推理判断题。根据最后一段“Just like me, Gentry is a mathematician and dancer, thus, her story resonates (引起共鸣) strongly with me, and I want to be like her in the future.(和我一样，Gentry也是一名数学家兼舞者，因此她的故事深深引起我的共鸣，我未来也想成为像她一样的人)”可知，作者认同Gentry兼顾学术和爱好的做法，因此可以推断作者会继续追求自己的舞蹈爱好。 C Learning a second language Some people learn a second language easily. Other people have trouble learning a new language. How can you help yourself learn a new language, such as English? There are several ways to make learning English a little easier and more interesting. The first step is to feel confident about learning English. If you believe that you can learn, you will learn. Be patient. You don’t have to understand everything all at once. It is natural to make mistakes when you learn something new. We can learn from our mistakes. The second step is to practise your English. For example, write in a diary every day. You will get used to writing in English, and you will feel comfortable expressing your ideas in English. After several weeks, you will see that your writing is improving. Besides, you must speak English every day. You can practise with your classmates after class. You will all make mistakes, but gradually you will become comfortable communicating in English. The third step is to keep a record of your language learning. You can write this in your diary. After each class, think about what you did. Did you answer a question correctly? Did you understand anything the teacher explained? Perhaps the lesson was difficult, but you tried to understand it. Write these achievements (成就) in your diary. You must be active in learning English and believe that you can do it. It is important to practise every day and make a record of your achievements. You will enjoy learning English, and you will have more confidence in yourself. 28．When you learn English, you do not need to ________. A．be patient B．make mistakes C．express your ideas in English D．understand everything at once 29．What is NOT helpful for you to enjoy learning English? A．To communicate in English. B．To worry about making mistakes. C．To think about what you did after each class. D．To make a record of the achievements. 30．What is the main idea of this passage? A．It is very important to learn English. B．Some people learn English easily while other people do not. C．There are ways to help you learn English more easily. D．Don’t worry about making mistakes when learning English. 【答案】28．D 29．B 30．C 【导语】本文是一篇说明文。本文主要介绍了几种帮助学习英语的方法，包括建立信心、坚持不懈地练习、记录学习成果等，从而使学习英语变得更简单和有趣。 【详解】28．细节理解题。根据第二段中“Be patient. You don’t have to understand everything all at once. (要有耐心。你不需要一下子理解所有的东西。)”可知，作者提到在刚开始学习英语的时候，你不需要一次性理解一切，这意味着你不需要立刻理解所有的事情。故选D。 29．细节理解题。根据第三段中“You will all make mistakes, but gradually you will become comfortable communicating in English.(你们都会犯错误，但渐渐地你们会习惯用英语交流。)”可知，不要担心自己犯错误，因为都会犯错误，渐渐地会习惯用英语交流，B选项“To worry about making mistakes.(担心犯错)”与原文信息不符。故选B。 30．主旨大意题。根据第一段中“There are several ways to make learning English a little easier and more interesting.( 有几种方法可以使英语学习更容易、更有趣。)”以及通读全文，本文主要介绍了几种帮助学习英语的方法，包括建立信心、坚持不懈地练习、记录学习成果等，从而使学习英语变得更简单和有趣。C选项“There are ways to help you learn English more easily.( 有很多方法可以帮助你更轻松地学习英语。)”概括文章的主要内容，符合题意。故选C。 D Microplastics have been discovered in the human heart and its innermost (最内层的) tissues for the first time. While the health effects of this are still unknown, the new study is yet another reminder of how widespread the world’s plastic problem has become within just a century. In the new study, scientists in China collected cardiac tissue samples (心脏组织样本) from 15 patients undergoing (经历，接受) heart operations, as well as blood samples taken both pre-operation and post-operation. Using a number of different imaging techniques, the team “detected tens to thousands of individual microplastic pieces in most tissue samples”, according to the news. While it’s clear that operations did introduce microplastics, there was also evidence that the foreign plastics were fixed firmly in the tissues before the patients were laid on the operating table. For starters, all of the blood samples contained microplastics. The blood samples taken post-operation contained microplastics of a smaller size and had more diverse types of plastics. This suggests that some microplastics got into the body during the operation. Out of the tissue samples, the researchers found nine types of plastic in five types of heart tissues. Some of these microplastics were evidently there before any operation took place. The team identified microscopic particles of poly (聚乙烯微粒), a plastic commonly used to take over from glass, in several heart tissues, which they say “cannot be caused by accidental contact during operations”. Other types of plastic found in the samples are those widely used in clothing, food containers, building and construction. “The detection of microplastics in a living body is alarming, and more studies are necessary to study why the microplastics appear in the cardiac tissues and the long-term effects of microplastics after the cardiac operation,” the study authors write in their conclusion. The impact of microplastics on animal health is not widely agreed upon nor fully understood, although evidence is starting to show that it has a harmful effect, unsurprisingly. 31．What do we know about the 15 patients? A．They had blood diseases. B．They offered images of samples. C．They had heart problems. D．They suffered from microplastics. 32．Why did blood samples taken post-operation contain more types of plastics? A．Detection techniques were improved. B．Some blood samples were polluted. C．Microplastics changed into more types. D．Operations introduced new microplastics. 33．What is the author’s attitude towards the detection of microplastics in cardiac tissues? A．Concerned B．Indifferent C．Thrilled D．Enthusiastic 34．What is the best title for the text? A．Researchers confirmed the effect of microplastics B．Researchers found microplastics in human hearts C．Microplastics will replace glass in heart operations D．Microplastics can be used in human heart operations 【答案】31．C 32．D 33．A 34．B 【导语】文章主要介绍了科学家首次在人类心脏及其最内层组织中发现了微塑料，并探讨了其来源及潜在影响。 【详解】31．细节理解题。根据第二段中“In the new study, scientists in China collected cardiac tissue samples (心脏组织样本) from 15 patients undergoing (经历，接受) heart operations (中国的科学家从15名接受心脏手术的患者身上采集了心脏组织样本)”可知，这15名患者有心脏问题。 32．细节理解题。根据第三段中“The blood samples taken post-operation contained microplastics of a smaller size and had more diverse types of plastics. This suggests that some microplastics got into the body during the operation. (术后采集的血样中含有尺寸更小、类型更多样的微塑料。这表明一些微塑料是在手术过程中进入体内的)”可知，术后血样含有更多类型的塑料是因为手术带入了新的微塑料。 33．推理判断题。根据第五段中“The detection of microplastics in a living body is alarming (在活体中检测到微塑料是令人担忧的)”可推知，作者对在心脏组织中检测到微塑料持担忧态度。 34．主旨大意题。结合第一段中“Microplastics have been discovered in the human heart and its innermost (最内层的) tissues for the first time. (微塑料首次在人类心脏及其最内层组织中被发现)”和下文对该研究的介绍可知，文章主要介绍了研究人员在人类心脏中发现微塑料的研究。故B项“Researchers found microplastics in human hearts (研究人员在人类心脏中发现微塑料)”能概括文章内容，最适合做文章标题。 第二节 （共5小题；每小题2分，共10分） 根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。选项中有两项为多余选项。 Being resilient (对困境有承受力的) means adapting well in the face of adversity, and building resilience requires consistent practice. 35 . The journey begins with small, deliberate changes in your daily habits. Cultivate a growth mindset Resilient people view adversity as temporary and informational, not as permanent reflections of their worth. Start by reframing negative thoughts: When you encounter a setback, ask “What can I learn from this?” rather than “Why me?” 36 . Build strong social connections Isolation (孤独) weakens resilience, while supportive relationships help relieve the pressure we face. Invest time in family, friends, or community groups where you feel understood and valued. 37 . Likewise, offer empathy to others. In doing so, you build a bridge of mutual trust. If your circle is limited, join clubs or volunteer. Even one reliable companion can provide encouragement during tough times. Prioritize physical self-care 38 . Regular exercise, adequate sleep, and balanced nutrition directly impact your emotional regulation and energy levels. Aim for at least 30 minutes of moderate workout daily. Establish a consistent sleep schedule to allow your brain to process emotions and recover. When your body is well-nourished and rested, you’ll have a greater physiological capacity to cope with psychological pressure. 39 Resilience involves adapting your strategies when situations change. Break overwhelming problems into smaller, manageable steps and focus on what you can control. Try alternative approaches if initial efforts fail. Equally important, know when to pause and accept that some factors are beyond your influence. These reduce frustration and empower you to navigate uncertainty with creativity and confidence, turning obstacles into negotiable challenges rather than dead ends. A．Set realistic, achievable daily goals B．Develop flexible problem-solving skills C．Share your falls with them, not just your rises D．Your mind and body are deeply interconnected E．Like a muscle, it grows stronger with intentional exercise F．Having some stress is normal and something we all experience G．This shift in perspective reduces helplessness and encourages active problem-solving 【答案】35．E 36．G 37．C 38．D 39．B 【导语】本文是一篇说明文，围绕抗挫力展开，介绍了抗挫力的内涵，系统阐述了培养抗挫力的四种有效途径，包括培养成长型思维、建立良好社交关系、重视身体自我养护以及锻炼灵活的问题处理能力，帮助人们在生活中更好地应对逆境。 【详解】35．上文“Being resilient (对困境有承受力的) means adapting well in the face of adversity, and building resilience requires consistent practice.(拥有抗挫力意味着在逆境中良好适应，培养抗挫力需要持之以恒的练习。)”点明培养抗挫力需要坚持锻炼。后文“The journey begins with small, deliberate changes in your daily habits.(这一过程始于日常生活中有意识的微小改变。)”说明培养抗挫力从日常小事做起。选项E“Like a muscle, it grows stronger with intentional exercise.(它就像肌肉一样，经过刻意锻炼会变得更强。)”将抗挫力比作肌肉，承接上文的持续练习，生动解释抗挫力可后天培养变强，衔接上下文。 36．上文“Start by reframing negative thoughts: When you encounter a setback, ask “What can I learn from this?” rather than “Why me?”(重新梳理消极想法：遭遇挫折时，反问自己“我能从中收获什么？”，而非抱怨“为什么是我？”)”介绍了成长型思维的思考方式，转变面对挫折的心态。选项G“This shift in perspective reduces helplessness and encourages active problem-solving.(这种视角的转变能够减少无助感，促使人们主动解决问题。)”句中This shift in perspective指代前文的思维转变，承接上文，点明积极心态带来的正向作用，贴合本段培养成长型思维的主旨。 37．上文“Invest time in family, friends, or community groups where you feel understood and valued.(用心经营能让自己被理解、被珍视的家人、朋友或社群关系。)”讲述要经营良好的社交关系。后文“Likewise, offer empathy to others.(同样，要给予他人共情。)”说明人际交往是双向付出。选项C“Share your falls with them, not just your rises.(向他们倾诉失意与挫折，而非只分享顺遂与喜悦。)”句中them指代前文的家人、朋友，提出真诚交心的相处方式，与后文双向共情形成呼应，契合本段建立良好社交联结的主题。 38．本段小标题为重视身体层面的自我养护。后文“Regular exercise, adequate sleep, and balanced nutrition directly impact your emotional regulation and energy levels.(规律运动、充足睡眠、均衡营养会直接影响人的情绪调节能力和精力状态。)”介绍身体养护对情绪和状态的重要影响。选项D“Your mind and body are deeply interconnected.(人的身心紧密相连。)”总领本段内容，点明身心关联的核心观点，引出下文身体状态影响心理抗压能力的具体论述。 39．本段后文“Resilience involves adapting your strategies when situations change.(抗挫力包含根据环境变化调整应对策略的能力。)”以及整段内容，主要讲述面对难题要灵活变通、调整方法、可控应对未知困境。选项B“Develop flexible problem-solving skills.(培养灵活解决问题的能力。)”作为本段小标题，精准概括本段核心主旨，统领全文段落内容。 第三部分 书面表达（共两节，32分） 第一节（共4小题；第40、41题各2分，第42题3分，第43题5分，共12分） 阅读下面短文，根据题目要求用英文回答问题。请在答题卡指定区域作答。 Does AI actually help students learn? A recent experiment in a high school provides a cautionary tale. Researchers at the University of Pennsylvania found that Turkish high school students who had access to ChatGPT while doing practice math problems did worse on a math test compared with students who didn’t have access to ChatGPT. Those with ChatGPT solved 48 percent more of the practice problems correctly, but they ultimately scored 17 percent worse on a test of the topic that the students were learning. A third group of students had access to a revised version of ChatGPT that functioned more like a tutor. This chatbot was programmed to provide hints without directly giving the answer. The students who used it did spectacularly better on the practice problems, solving 27 percent more of them correctly compared with students who did their practice work without any high-tech aids. But on a test afterwards, these AI-tutored students did no better. Students who just did their practice problems the old fashioned way — on their own — matched their test scores. The researchers titled their paper, “Generative AI Can Harm Learning,” to make clear to parents and educators that the current crop of freely available AI chatbots can “substantially prevent learning.” Even a fine-tuned version of ChatGPT designed to mimic a tutor doesn’t necessarily help. The researchers believe the problem is that students are using the chatbot as a “crutch.” When they analyzed the questions that students typed into ChatGPT, students often simply asked for the answer. Students were not building the skills that come from solving the problems themselves. ChatGPT’s errors also may have been a contributing factor. The chatbot only answered the math problems correctly half of the time. Its arithmetic computations were wrong 8 percent of the time, but the bigger problem was that its step-by-step approach for how to solve a problem was wrong 42 percent of the time. The tutoring version of ChatGPT was directly fed the correct solutions and these errors were minimized. ChatGPT also seems to produce overconfidence. In surveys that accompanied the experiment, students said they did not think that ChatGPT caused them to learn less even though they had. Students with the AI tutor thought they had done significantly better on the test even though they did not. (It’s also another good reminder to all of us that our perceptions of how much we’ve learned are often wrong.) ChatGPT is not the first technology to present a tradeoff in education. Typewriters and computers reduce the need for handwriting. Calculators reduce the need for arithmetic. When students have access to ChatGPT, they might answer more problems correctly, but learn less. Getting the right result to one problem won’t help them with the next one. 40．What was the main finding about students who used ChatGPT for math practice? 41．Besides misuse, what other factors may affect the learning outcomes of the students who use ChatGPT? 42．Please decide which part is false in the following statement, then underline it and explain why. ➤When students use ChatGPT to solve problems, they might get more correct answers and learn more. 43．How can you ensure you are still learning rather than just getting answers when using AI tools for schoolwork? (In about 40 words) 【答案】40．They solved more practice problems correctly but scored much worse in the follow-up math test. 41．ChatGPT’s errors and students’ overconfidence. 42．When students use ChatGPT to solve problems, they might get more correct answers and learn more. According to the passage, students using ChatGPT solved more practice problems but scored worse on tests, and the researchers found generative AI can harm learning. 43．I should ask AI for hints and thinking methods instead of direct answers. I will finish thinking independently first and summarize problem-solving skills after using AI. 【导语】本文主要介绍了研究发现ChatGPT可能损害学生学习，即使作为导师也不一定有帮助，原因包括滥用、错误和过度自信。 【详解】40．考查细节理解。根据第二段“Researchers at the University of Pennsylvania found that Turkish high school students who had access to ChatGPT while doing practice math problems did worse on a math test compared with students who didn’t have access to ChatGPT. Those with ChatGPT solved 48 percent more of the practice problems correctly, but they ultimately scored 17 percent worse on a test of the topic that the students were learning. (宾夕法尼亚大学的研究人员发现，在做数学练习题时使用ChatGPT的土耳其高中生，在数学测试中的表现比不使用ChatGPT的学生差。那些使用 ChatGPT 的学生练习题正确率高出48%，但在对应所学知识点的正式测试中，最终得分反而低了17%。)”可知，使用ChatGPT的学生练习正确率更高，但正式考试成绩明显下滑，不利于真正学习。 41．考查细节理解。根据第六段“ChatGPT’s errors also may have been a contributing factor. The chatbot only answered the math problems correctly half of the time. Its arithmetic computations were wrong 8 percent of the time, but the bigger problem was that its step-by-step approach for how to solve a problem was wrong 42 percent of the time. (ChatGPT的错误也可能是一个因素。聊天机器人只有一半的数学题回答正确。它的算术计算错误率为8%，但更大的问题是它解决问题的步骤方法错误率为42%。)”及第七段“ChatGPT also seems to produce overconfidence. In surveys that accompanied the experiment, students said they did not think that ChatGPT caused them to learn less even though they had. Students with the AI tutor thought they had done significantly better on the test even though they did not. (ChatGPT似乎还会导致过度自信。在实验附带的调查中，学生们表示他们不认为ChatGPT导致他们学得更少，尽管实际上他们学得更少。使用AI导师的学生认为他们在测试中表现得更好，尽管实际上并没有。)”可知，其他因素包括ChatGPT的错误和学生的过度自信。 42．考查细节判断。根据第二段“Those with ChatGPT solved 48 percent more of the practice problems correctly, but they ultimately scored 17 percent worse on a test of the topic that the students were learning. (使用ChatGPT的学生正确解决的练习题比不使用的多48%，但在学习主题的测试中得分最终低17%。)”可知，原句中learn more表述错误。因为使用ChatGPT可以帮助学生在实践中获得更正确的答案，但实际上会让他们学到更少的知识。 43．开放性题目。此题要求回答：在使用人工智能工具做作业时，你如何确保自己仍在学习，而不仅仅是得到答案？答案不唯一，合理即可。例如：我应该向人工智能寻求提示和思考方法，而不是直接的答案。我将首先完成独立思考，并在使用人工智能后总结解决问题的能力。 第二节（20分） 44．假设你是红星中学高三学生李华。你的外国好友 Jim来信向你倾诉，称自己近来承受巨大压力，情绪低落，询问你的建议。请你用英文给他回信，内容包括： （1）提两条缓解压力的建议； （2）每条建议的理由。 提示： （1）词数80左右； （2）开头和结尾已给出，不计入总字数。 Dear Jim, ______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ Yours, Li Hua 【答案】例文 Dear Jim, I’m sorry to hear that you are suffering from heavy pressure these days. First, I recommend you take exercise regularly, such as jogging or walking outdoors. Sports can release tiredness and cheer you up quickly. Besides, it is wise to share your worries with your family or close friends. Pouring out your worries will stop your negative feelings building up in your heart. Don’t push yourself too much. It’s normal to feel anxious and a small relaxation can make a big difference. 【导语】本篇书面表达要求考生给外国好友Jim写一封回信，就如何缓解压力方面给出建议。 【详解】1.词汇积累 压力：pressure→stress 锻炼：take exercise→work out 焦虑的：anxious→restless 疲惫：tiredness→exhaustion 2.句式拓展 简单句变复合句 原句：Pouring out your worries will stop your negative feelings building up in your heart. 拓展句：Pouring out your worries is a way that can stop your negative feelings building up in your heart. 【点睛】【高分句型1】I’m sorry to hear that you are suffering from heavy pressure these days. (运用了that引导的宾语从句) 【高分句型2】 Besides, it is wise to share your worries with your family and/or close friends.

With trembling hands, I opened it and was overjoyed. It was the 11 (good) news I had ever had! The moment I had been dreaming of arrived. I felt a great weight 12 (lift) off my shoulders. My hard work had paid off, and a new chapter of my life was about to begin, filling me with excitement for all 13 possibilities that lay ahead. B Many people who grow up in small towns find themselves counting the 14 (day) until they get to escape their roots and plant new ones in bigger, “better” places. And that’s fine.

Up to now, being from a small town 16 (teach) me so many important lessons, 17 I will carry with me for the rest of my life. C Most people believe when they live comfortably and earn enough money, they will have worries. However, most people never feel they 18 (earn) enough.

Students will love exploring while also gaining invaluable experience by designing and conducting experiments. Sunscreen Experiment Kids often don’t enjoy being told they need sunscreen, so showing its power through demonstration can help them see its value. This science fair project uses simple white beads (珠子) that change color when exposed to UV rays (紫外线) so children can compare the effectiveness of different sunscreen products. Start this experiment by applying some of each sunscreen type on paper and placing both pieces of paper in direct sunlight for several hours. Sundial (日晷) Experiment Using a sundial to tell time is a fascinating science activity that helps students gain knowledge of shadows and the movement of sunlight across the sky. Through this hands-on experiment, students gain an opportunity to see how people in previous times knew time without clocks or watches. Start this experiment by asking students to identify an outdoor spot that receives sunlight all day, placing a flat board there, tracing the shadows onto it and noting where the shadows will fall at certain points of the day. Mineral Experiment Students learn to identify rocks and minerals through this simple experiment. They use a plate to test the hardness of various common minerals. They also observe how these minerals form crystals (晶体) and how they break apart differently from others. This lesson helps students understand the characteristics and uses of different minerals. Students can even form “companies” and compete to mine different types of rocks with specific features. 21．What is the main purpose of using beads in the sunscreen experiment? A．To compare the prices of sunscreen. B．To show the effectiveness of sunscreen. C．To analyze the impact of sunscreen on skin. D．To demonstrate chemical reactions in sunscreen. 22．How do students begin the sundial experiment? A．By building a sundial from beginning. B．By comparing different types of sundials. C．By measuring the length of their shadows. D．By identifying a sunny spot and using a flat board. 23．What does the mineral experiment allow students to do? A．Observe crystal formation. B．Learn geological history. C．Sell rocks they mine. D．Form companies. B As we grow up, it becomes natural for us to lose contact with the hobbies that once were important in our lives. While it’s painful to accept this, the new reality becomes normal for most of us as we face new academic, adult and job responsibilities. I’ve been dancing since I was four and I plan to continue dancing in college. However, I’ve always feared that dancing will affect my study and eventually become a happy memory of my childhood. After learning about Sommer Gentry’s story, I had an answer. Sommer Gentry, previously a professor of mathematics at the United States Naval Academy and a coach at the Naval Academy’s Swing Dance Club, is currently a teacher at NYU Grossman School of Medicine. Gentry and her husband also started a swing dance community to introduce non-dancers to swing dance. Through teaching, Gentry was inspired to view dancing from an engineering point of view. She said, “I realized it is an engineering question: How do you dance well with someone? It’d be great to give people mathematical and engineering proofs that they have to dance the way I say.” Gentry investigated the complex haptic (触觉的) communication behind the moves in swing dance and showed that two persons could move in coordination (协调) with pure haptic communication. She entered an exciting area of research which is about engineering, psychology and human motor control. It’s incredibly inspiring that Gentry was able to intertwine her academic work with her love for dancing. Gentry said, “It means that even when I’m dancing outside, I’m thinking about my research project.” Gentry found that digging into her academic interest does not mean letting go of her other non-academic ones. Instead, she found a way to include both in her professional life. Just like me, Gentry is a mathematician and dancer, thus, her story resonates (引起共鸣) strongly with me, and I want to be like her in the future. 24．What did the author think of dancing before learning of Gentry’s story? A．It was too challenging for her. B．It might disappear from her life. C．It brought her pleasant memories. D．It developed her sense of responsibility. 25．According to the fourth paragraph, which of the following best summarizes the main idea? A．Gentry chose academics over dancing. B．Gentry gave up dancing due to its irrelevance to her research. C．Dancing has no connection to engineering or psychology for Gentry. D．Gentry viewed dancing as an engineering problem. 26．What does the underlined word in paragraph 5 probably mean? A．Hardly balance. B．Carefully compare. C．Closely combine. D．Successfully challenge. 27．What can we infer about the author from the last paragraph? A．She has decided to change her major. B．She will continue to pursue her hobby. C．She used to be Sommer Gentry’s student. D．She originally had little interest in engineering. C Learning a second language Some people learn a second language easily. Other people have trouble learning a new language. How can you help yourself learn a new language, such as English? There are several ways to make learning English a little easier and more interesting. The first step is to feel confident about learning English. If you believe that you can learn, you will learn. Be patient. You don’t have to understand everything all at once. It is natural to make mistakes when you learn something new. We can learn from our mistakes. The second step is to practise your English. For example, write in a diary every day. You will get used to writing in English, and you will feel comfortable expressing your ideas in English. After several weeks, you will see that your writing is improving. Besides, you must speak English every day. You can practise with your classmates after class. You will all make mistakes, but gradually you will become comfortable communicating in English. The third step is to keep a record of your language learning. You can write this in your diary. After each class, think about what you did. Did you answer a question correctly? Did you understand anything the teacher explained? Perhaps the lesson was difficult, but you tried to understand it. Write these achievements (成就) in your diary. You must be active in learning English and believe that you can do it. It is important to practise every day and make a record of your achievements. You will enjoy learning English, and you will have more confidence in yourself. 28．When you learn English, you do not need to ________. A．be patient B．make mistakes C．express your ideas in English D．understand everything at once 29．What is NOT helpful for you to enjoy learning English? A．To communicate in English. B．To worry about making mistakes. C．To think about what you did after each class. D．To make a record of the achievements. 30．What is the main idea of this passage? A．It is very important to learn English. B．Some people learn English easily while other people do not. C．There are ways to help you learn English more easily. D．Don’t worry about making mistakes when learning English. D Microplastics have been discovered in the human heart and its innermost (最内层的) tissues for the first time. While the health effects of this are still unknown, the new study is yet another reminder of how widespread the world’s plastic problem has become within just a century. In the new study, scientists in China collected cardiac tissue samples (心脏组织样本) from 15 patients undergoing (经历，接受) heart operations, as well as blood samples taken both pre-operation and post-operation. Using a number of different imaging techniques, the team “detected tens to thousands of individual microplastic pieces in most tissue samples”, according to the news. While it’s clear that operations did introduce microplastics, there was also evidence that the foreign plastics were fixed firmly in the tissues before the patients were laid on the operating table. For starters, all of the blood samples contained microplastics. The blood samples taken post-operation contained microplastics of a smaller size and had more diverse types of plastics. This suggests that some microplastics got into the body during the operation. Out of the tissue samples, the researchers found nine types of plastic in five types of heart tissues. Some of these microplastics were evidently there before any operation took place. The team identified microscopic particles of poly (聚乙烯微粒), a plastic commonly used to take over from glass, in several heart tissues, which they say “cannot be caused by accidental contact during operations”. Other types of plastic found in the samples are those widely used in clothing, food containers, building and construction. “The detection of microplastics in a living body is alarming, and more studies are necessary to study why the microplastics appear in the cardiac tissues and the long-term effects of microplastics after the cardiac operation,” the study authors write in their conclusion. The impact of microplastics on animal health is not widely agreed upon nor fully understood, although evidence is starting to show that it has a harmful effect, unsurprisingly. 31．What do we know about the 15 patients? A．They had blood diseases. B．They offered images of samples. C．They had heart problems. D．They suffered from microplastics. 32．Why did blood samples taken post-operation contain more types of plastics? A．Detection techniques were improved. B．Some blood samples were polluted. C．Microplastics changed into more types. D．Operations introduced new microplastics. 33．What is the author’s attitude towards the detection of microplastics in cardiac tissues? A．Concerned B．Indifferent C．Thrilled D．Enthusiastic 34．What is the best title for the text? A．Researchers confirmed the effect of microplastics B．Researchers found microplastics in human hearts C．Microplastics will replace glass in heart operations D．Microplastics can be used in human heart operations 第二节 （共5小题；每小题2分，共10分） 根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。选项中有两项为多余选项。 Being resilient (对困境有承受力的) means adapting well in the face of adversity, and building resilience requires consistent practice. 35 . The journey begins with small, deliberate changes in your daily habits. Cultivate a growth mindset Resilient people view adversity as temporary and informational, not as permanent reflections of their worth. Start by reframing negative thoughts: When you encounter a setback, ask “What can I learn from this?” rather than “Why me?” 36 . Build strong social connections Isolation (孤独) weakens resilience, while supportive relationships help relieve the pressure we face. Invest time in family, friends, or community groups where you feel understood and valued. 37 . Likewise, offer empathy to others. In doing so, you build a bridge of mutual trust. If your circle is limited, join clubs or volunteer. Even one reliable companion can provide encouragement during tough times. Prioritize physical self-care 38 .

With trembling hands, I opened it and was overjoyed. It was the 11 (good) news I had ever had! The moment I had been dreaming of arrived. I felt a great weight 12 (lift) off my shoulders. My hard work had paid off, and a new chapter of my life was about to begin, filling me with excitement for all 13 possibilities that lay ahead. B Many people who grow up in small towns find themselves counting the 14 (day) until they get to escape their roots and plant new ones in bigger, “better” places. And that’s fine. But they say it’s important to remember where you come from. When 15 (think) about that, I can’t help having an overwhelming feeling of gratitude for my root. Up to now, being from a small town 16 (teach) me so many important lessons, 17 I will carry with me for the rest of my life. C Most people believe when they live comfortably and earn enough money, they will have worries. However, most people never feel they 18 (earn) enough. Jason Harley decided to drop out of this kind of lifestyle, and he discovered that having only a little money made him free. Are there any things he misses from his past? “No, I’m much happier now, 19 I am living according to my values.

Students will love exploring while also gaining invaluable experience by designing and conducting experiments. Sunscreen Experiment Kids often don’t enjoy being told they need sunscreen, so showing its power through demonstration can help them see its value. This science fair project uses simple white beads (珠子) that change color when exposed to UV rays (紫外线) so children can compare the effectiveness of different sunscreen products. Start this experiment by applying some of each sunscreen type on paper and placing both pieces of paper in direct sunlight for several hours. Sundial (日晷) Experiment Using a sundial to tell time is a fascinating science activity that helps students gain knowledge of shadows and the movement of sunlight across the sky. Through this hands-on experiment, students gain an opportunity to see how people in previous times knew time without clocks or watches. Start this experiment by asking students to identify an outdoor spot that receives sunlight all day, placing a flat board there, tracing the shadows onto it and noting where the shadows will fall at certain points of the day. Mineral Experiment Students learn to identify rocks and minerals through this simple experiment. They use a plate to test the hardness of various common minerals. They also observe how these minerals form crystals (晶体) and how they break apart differently from others. This lesson helps students understand the characteristics and uses of different minerals. Students can even form “companies” and compete to mine different types of rocks with specific features. 21．What is the main purpose of using beads in the sunscreen experiment? A．To compare the prices of sunscreen. B．To show the effectiveness of sunscreen. C．To analyze the impact of sunscreen on skin. D．To demonstrate chemical reactions in sunscreen. 22．How do students begin the sundial experiment? A．By building a sundial from beginning. B．By comparing different types of sundials. C．By measuring the length of their shadows. D．By identifying a sunny spot and using a flat board. 23．What does the mineral experiment allow students to do? A．Observe crystal formation. B．Learn geological history. C．Sell rocks they mine. D．Form companies. B As we grow up, it becomes natural for us to lose contact with the hobbies that once were important in our lives. While it’s painful to accept this, the new reality becomes normal for most of us as we face new academic, adult and job responsibilities. I’ve been dancing since I was four and I plan to continue dancing in college. However, I’ve always feared that dancing will affect my study and eventually become a happy memory of my childhood. After learning about Sommer Gentry’s story, I had an answer. Sommer Gentry, previously a professor of mathematics at the United States Naval Academy and a coach at the Naval Academy’s Swing Dance Club, is currently a teacher at NYU Grossman School of Medicine. Gentry and her husband also started a swing dance community to introduce non-dancers to swing dance. Through teaching, Gentry was inspired to view dancing from an engineering point of view. She said, “I realized it is an engineering question: How do you dance well with someone? It’d be great to give people mathematical and engineering proofs that they have to dance the way I say.” Gentry investigated the complex haptic (触觉的) communication behind the moves in swing dance and showed that two persons could move in coordination (协调) with pure haptic communication. She entered an exciting area of research which is about engineering, psychology and human motor control. It’s incredibly inspiring that Gentry was able to intertwine her academic work with her love for dancing. Gentry said, “It means that even when I’m dancing outside, I’m thinking about my research project.” Gentry found that digging into her academic interest does not mean letting go of her other non-academic ones. Instead, she found a way to include both in her professional life. Just like me, Gentry is a mathematician and dancer, thus, her story resonates (引起共鸣) strongly with me, and I want to be like her in the future. 24．What did the author think of dancing before learning of Gentry’s story? A．It was too challenging for her. B．It might disappear from her life. C．It brought her pleasant memories. D．It developed her sense of responsibility. 25．According to the fourth paragraph, which of the following best summarizes the main idea? A．Gentry chose academics over dancing. B．Gentry gave up dancing due to its irrelevance to her research. C．Dancing has no connection to engineering or psychology for Gentry. D．Gentry viewed dancing as an engineering problem. 26．What does the underlined word in paragraph 5 probably mean? A．Hardly balance. B．Carefully compare. C．Closely combine. D．Successfully challenge. 27．What can we infer about the author from the last paragraph? A．She has decided to change her major. B．She will continue to pursue her hobby. C．She used to be Sommer Gentry’s student. D．She originally had little interest in engineering. C Learning a second language Some people learn a second language easily. Other people have trouble learning a new language. How can you help yourself learn a new language, such as English? There are several ways to make learning English a little easier and more interesting. The first step is to feel confident about learning English. If you believe that you can learn, you will learn. Be patient. You don’t have to understand everything all at once. It is natural to make mistakes when you learn something new. We can learn from our mistakes. The second step is to practise your English. For example, write in a diary every day. You will get used to writing in English, and you will feel comfortable expressing your ideas in English. After several weeks, you will see that your writing is improving. Besides, you must speak English every day. You can practise with your classmates after class. You will all make mistakes, but gradually you will become comfortable communicating in English. The third step is to keep a record of your language learning. You can write this in your diary. After each class, think about what you did. Did you answer a question correctly? Did you understand anything the teacher explained? Perhaps the lesson was difficult, but you tried to understand it. Write these achievements (成就) in your diary. You must be active in learning English and believe that you can do it. It is important to practise every day and make a record of your achievements. You will enjoy learning English, and you will have more confidence in yourself. 28．When you learn English, you do not need to ________. A．be patient B．make mistakes C．express your ideas in English D．understand everything at once 29．What is NOT helpful for you to enjoy learning English? A．To communicate in English. B．To worry about making mistakes. C．To think about what you did after each class. D．To make a record of the achievements. 30．What is the main idea of this passage? A．It is very important to learn English. B．Some people learn English easily while other people do not. C．There are ways to help you learn English more easily. D．Don’t worry about making mistakes when learning English. D Microplastics have been discovered in the human heart and its innermost (最内层的) tissues for the first time. While the health effects of this are still unknown, the new study is yet another reminder of how widespread the world’s plastic problem has become within just a century. In the new study, scientists in China collected cardiac tissue samples (心脏组织样本) from 15 patients undergoing (经历，接受) heart operations, as well as blood samples taken both pre-operation and post-operation. Using a number of different imaging techniques, the team “detected tens to thousands of individual microplastic pieces in most tissue samples”, according to the news. While it’s clear that operations did introduce microplastics, there was also evidence that the foreign plastics were fixed firmly in the tissues before the patients were laid on the operating table. For starters, all of the blood samples contained microplastics. The blood samples taken post-operation contained microplastics of a smaller size and had more diverse types of plastics. This suggests that some microplastics got into the body during the operation. Out of the tissue samples, the researchers found nine types of plastic in five types of heart tissues. Some of these microplastics were evidently there before any operation took place. The team identified microscopic particles of poly (聚乙烯微粒), a plastic commonly used to take over from glass, in several heart tissues, which they say “cannot be caused by accidental contact during operations”. Other types of plastic found in the samples are those widely used in clothing, food containers, building and construction. “The detection of microplastics in a living body is alarming, and more studies are necessary to study why the microplastics appear in the cardiac tissues and the long-term effects of microplastics after the cardiac operation,” the study authors write in their conclusion. The impact of microplastics on animal health is not widely agreed upon nor fully understood, although evidence is starting to show that it has a harmful effect, unsurprisingly. 31．What do we know about the 15 patients? A．They had blood diseases. B．They offered images of samples. C．They had heart problems. D．They suffered from microplastics. 32．Why did blood samples taken post-operation contain more types of plastics? A．Detection techniques were improved. B．Some blood samples were polluted. C．Microplastics changed into more types. D．Operations introduced new microplastics. 33．What is the author’s attitude towards the detection of microplastics in cardiac tissues? A．Concerned B．Indifferent C．Thrilled D．Enthusiastic 34．What is the best title for the text? A．Researchers confirmed the effect of microplastics B．Researchers found microplastics in human hearts C．Microplastics will replace glass in heart operations D．Microplastics can be used in human heart operations 第二节 （共5小题；每小题2分，共10分） 根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项，并在答题卡上将该项涂黑。选项中有两项为多余选项。 Being resilient (对困境有承受力的) means adapting well in the face of adversity, and building resilience requires consistent practice. 35 . The journey begins with small, deliberate changes in your daily habits. Cultivate a growth mindset Resilient people view adversity as temporary and informational, not as permanent reflections of their worth. Start by reframing negative thoughts: When you encounter a setback, ask “What can I learn from this?” rather than “Why me?” 36 . Build strong social connections Isolation (孤独) weakens resilience, while supportive relationships help relieve the pressure we face. Invest time in family, friends, or community groups where you feel understood and valued. 37 . Likewise, offer empathy to others. In doing so, you build a bridge of mutual trust. If your circle is limited, join clubs or volunteer. Even one reliable companion can provide encouragement during tough times. Prioritize physical self-care 38 . Regular exercise, adequate sleep, and balanced nutrition directly impact your emotional regulation and energy levels. Aim for at least 30 minutes of moderate workout daily. Establish a consistent sleep schedule to allow your brain to process emotions and recover. When your body is well-nourished and rested, you’ll have a greater physiological capacity to cope with psychological pressure. 39 Resilience involves adapting your strategies when situations change. Break overwhelming problems into smaller, manageable steps and focus on what you can control. Try alternative approaches if initial efforts fail. Equally important, know when to pause and accept that some factors are beyond your influence. These reduce frustration and empower you to navigate uncertainty with creativity and confidence, turning obstacles into negotiable challenges rather than dead ends. A．Set realistic, achievable daily goals B．Develop flexible problem-solving skills C．Share your falls with them, not just your rises D．Your mind and body are deeply interconnected E．Like a muscle, it grows stronger with intentional exercise F．Having some stress is normal and something we all experience G．This shift in perspective reduces helplessness and encourages active problem-solving 第三部分 书面表达（共两节，32分） 第一节（共4小题；第40、41题各2分，第42题3分，第43题5分，共12分） 阅读下面短文，根据题目要求用英文回答问题。请在答题卡指定区域作答。 Does AI actually help students learn? A recent experiment in a high school provides a cautionary tale. Researchers at the University of Pennsylvania found that Turkish high school students who had access to ChatGPT while doing practice math problems did worse on a math test compared with students who didn’t have access to ChatGPT. Those with ChatGPT solved 48 percent more of the practice problems correctly, but they ultimately scored 17 percent worse on a test of the topic that the students were learning. A third group of students had access to a revised version of ChatGPT that functioned more like a tutor. This chatbot was programmed to provide hints without directly giving the answer. The students who used it did spectacularly better on the practice problems, solving 27 percent more of them correctly compared with students who did their practice work without any high-tech aids. But on a test afterwards, these AI-tutored students did no better. Students who just did their practice problems the old fashioned way — on their own — matched their test scores. The researchers titled their paper, “Generative AI Can Harm Learning,” to make clear to parents and educators that the current crop of freely available AI chatbots can “substantially prevent learning.” Even a fine-tuned version of ChatGPT designed to mimic a tutor doesn’t necessarily help. The researchers believe the problem is that students are using the chatbot as a “crutch.” When they analyzed the questions that students typed into ChatGPT, students often simply asked for the answer. Students were not building the skills that come from solving the problems themselves. ChatGPT’s errors also may have been a contributing factor. The chatbot only answered the math problems correctly half of the time. Its arithmetic computations were wrong 8 percent of the time, but the bigger problem was that its step-by-step approach for how to solve a problem was wrong 42 percent of the time. The tutoring version of ChatGPT was directly fed the correct solutions and these errors were minimized. ChatGPT also seems to produce overconfidence. In surveys that accompanied the experiment, students said they did not think that ChatGPT caused them to learn less even though they had. Students with the AI tutor thought they had done significantly better on the test even though they did not. (It’s also another good reminder to all of us that our perceptions of how much we’ve learned are often wrong.) ChatGPT is not the first technology to present a tradeoff in education. Typewriters and computers reduce the need for handwriting. Calculators reduce the need for arithmetic. When students have access to ChatGPT, they might answer more problems correctly, but learn less. Getting the right result to one problem won’t help them with the next one. 40．What was the main finding about students who used ChatGPT for math practice? 41．Besides misuse, what other factors may affect the learning outcomes of the students who use ChatGPT? 42．Please decide which part is false in the following statement, then underline it and explain why. ➤When students use ChatGPT to solve problems, they might get more correct answers and learn more. 43．How can you ensure you are still learning rather than just getting answers when using AI tools for schoolwork?
