Traditional AI tools often depend on fixed answers stored in their systems, but DeepSeek-R1 works differently.It applies a method called reinforcement learning, which mimics how humans think and learn from mistakes.Imagine a student facing a difficult algebra problem.Instead of simply giving the correct answer, the AI acts like a thoughtful teacher—it explains the problem-solving process step-by-step, points out where errors might occur, and asks questions to develop independent thinking skills. The technology serves purposes beyond school subjects.When used for language practice, it listens to students' speech through microphones, checks pronunciation accuracy instantly, and offers real-time feedback.Teachers also benefit greatly：the AI can design class activities matching official learning requirements, forecast which topics students may find challenging by analyzing past performance records, and even create special tests that automatically become harder or easier based on each learner's ability.This“smart testing” system saves educators time while keeping students appropriately challenged. Yet some concerns exist.Education experts worry that depending too much on AI could make classrooms less interactive.DeepSeek's team responds by clearly stating their tool is designed to support, not take over, human teachers.Researcher Dr.Li explains，“We want machines to handle routine work like grading papers, so teachers can spend more energy on creative teaching methods and building students' imagination.” Future plans for DeepSeek-R1 include adding virtual reality(VR)functions.Students might soon“walk through”ancient cities during history lessons or“enter” human cells to study biology in 3D simulated environments.Although discussions continue about whether AI should play such a big role in education, its impact is undeniable.These intelligent systems are changing learning methods worldwide, proving that technology works best when combined with human guidance.As classrooms evolve, tools like DeepSeek-R1 remind us that real progress lies not in choosing between machines and people, but in making them work together wisely. 【语篇解读】　本文是一篇说明文。文章主要介绍了中国科技公司DeepSeek推出的最新产品DeepSeek-R1在教育创新方面的应用，包括其如何通过智能计算机系统为全球学习者提供定制化的学习计划，以及在教育领域的多种应用和未来规划。 1．What function does DeepSeek-R1 provide in language learning?

D．Focuses solely on grammar drills. 细节理解题。根据文章第三段中的“When used for language practice, it listens to students' speech through microphones, checks pronunciation accuracy instantly, and offers real-time feedback.”可知，DeepSeek-R1在语言学习方面可以提供即时的发音纠正。故选B项。 √ 2．How does DeepSeek-R1's“smart testing”system adapt to students? A．By randomly increasing the number of test questions. B．Requiring teachers to manually set difficulty levels. C．Repeating the same questions until students memorize answers. D．By automatically adjusting difficulty based on individual ability. 细节理解题。根据文章第三段中的“and even create special tests that automatically become harder or easier based on each learner's ability.This‘smart testing’system saves educators time while keeping students appropriately challenged.”可知，DeepSeek-R1的“智能测试”系统可以根据学生的个人能力自动调整难度。故选D项。 √ 3．What does Dr.Li imply about DeepSeek-R1's role in education? A．It will fully replace human teachers in the future. B．It prioritizes automating all teaching processes. C．It aims to help teachers focus on innovative tasks. D．It increases students' dependence on pre-programmed answers. 推理判断题。根据文章第四段中的“Researcher Dr.Li explains，‘We want machines to handle routine work like grading papers, so teachers can spend more energy on creative teaching methods and building students' imagination.’”可知，李博士暗示DeepSeek-R1在教育中的角色是帮助教师专注于创新任务。故选C项。 √ 4．What is the best title of the passage? A．AI and Human Partnership in Education B．AI's Ethical Risks in Education C．Reinforcement Learning in China D．VR：The Future of Classrooms 标题归纳题。文章主要介绍了DeepSeek-R1在教育领域的应用，强调了人工智能与人类合作的必要性。因此，A项(教育中的人工智能与人类合作)最符合文章主旨。故选A项。 √ B By the time you reach maturity, the brain networks that govern cognitive (认知的) control have been well developed.Years of learning and experience have conditioned your brain to differentiate between important information and distractions (分心的事).In theory, your capacity for focus should be at its best. However, daily life variables will often throw obstacles in your path.To stay at the top of your game, it's important to recognize and address the physical and emotional factors that interfere with your focus.Your brain is a flesh-and-blood organ, and what's happening in your body—from aging to diseases to lifestyle factors such as sleep and alcohol use—will play a key role in your ability to pay attention.Neurochemical fluctuations(波动) that govern your mood also play a role. Love it or hate it, we live in the digital age and there's no going back.Today's digital distractions pose challenges to the brain networks that regulate attention.In many ways, our smartphones inhibit focus.The most obvious distractions are the alerts that come from the phone itself.Simply hearing the sound or feeling the vibration can interrupt a task, even without checking the message.Once you engage with the phone, such as answering a call, it's easy for your attention to shift to other activities, like answering email.Bright colors, and catchy tunes heighten the attraction of apps and enhance their ability to draw attention away from tasks. The pull is even stronger for activities like social media or playing a game.Research has shown that social media cues, such as “likes” or pictures of friends, stimulate a dopamine surge—the neurotransmitter associated with pleasure and reward—which may reduce the motivation to focus. A 2018 survey found Americans check their mobile phones an average of 80 times a day；the highest users surveyed topped 300 daily checks.But each time we interrupt something we were doing to check our phones, we break our concentration and have to start over. In addition to the distraction factor associated with media use, exposure to blue light from phone, tablet, and computer screens can affect sleep.A 2017 study published in the journal Chronobiology International, involving young adults in their 20s, showed that blue-light exposure before bed cut down sleep time by roughly 16 minutes. 【语篇解读】　本文是一篇说明文。文章介绍了数字时代智能手机等带来的干扰，包括打断任务、降低专注力和影响睡眠。 5．What does the second paragraph mainly discuss? A．What people do to enhance focus. B．What affects people's concentration. C．How aging impacts cognitive control. D．How people overcome daily difficulties. 段落大意题。根据第二段“However, daily life variables will often throw obstacles in your path.To stay at the top of your game, it's important to recognize and address the physical and emotional factors that interfere with your focus.”以及后面具体阐述身体和情绪等因素如何影响注意力的内容可知，该段主要讨论的是影响人们注意力的因素。故选B。 √ 6．How do smartphones impact focus? A．They make tasks more engaging. B．They help manage time effectively. C．They generate constant distractions. D．They reduce distractions significantly. 细节理解题。根据第三段“The most obvious distractions are the alerts...like answering email.”可知，智能手机会不断产生诸如提示音、震动等干扰，让人注意力分散。故选C。 √ 7．Why are social media and games distracting? A．They challenge critical thinking. B．They offer instant financial rewards. C．They provide social connection. D．They bring a sense of satisfaction. 推理判断题。根据第四段“Research has shown that social media cues, such as‘likes’or pictures of friends, stimulate a dopamine surge—the neurotransmitter associated with pleasure and reward—which may reduce the motivation to focus.”可知，社交媒体和游戏会刺激多巴胺分泌，带来愉悦和满足感。故选D。 √ 8．Why is the 2018 survey mentioned in the text? A．To support a claim. B．To provide context. C．To show differences. D．To illustrate a pattern. 推理判断题。根据第五段以及前面提到的智能手机对注意力的干扰可知，提到2018年的调查是为了用数据支持“智能手机会打断人们的注意力”这一观点。故选A。 √ Ⅱ.语法填空(本题共10个小题，每小题1.5分，共15分) Morse code (摩斯密码) is named 1____________ Samuel F．B.Morse, a painter and founder of the National Academy of Design.He, along with two other engineers, developed the telegraph and the code 2____________ use a set of dots and dashes or short and long pulses to represent each letter of the English alphabet.The first working telegraph was produced in 1836. 考查介词。短语be named after/for表示“以……命名”。故填after/for。 考查定语从句。定语从句修饰先行词code，引导词在从句作主语，指物，故填that/which。 after/for that/which This made 3____________ possible to send messages over any 4____________ (distant).The first Morse code message 5____________ (send) from Washington to Baltimore in 1844. 考查名词。作介词的宾语，用名词distance，不可数。故填distance。 考查时态和语态。主语message与谓语构成被动关系，根据后文in 1844可知为一般过去时的被动语态，谓语用单数。故填was sent。 考查it用法。此处为make it adj.to do sth，it作形式宾语，故填it。 it distance was sent Today experienced operators copy received text without the need to write as they receive.Morse code can be sent 6____________ (use) sound or light, as sometimes happens between ships at sea.It can be used to send messages in English 7____________ many other languages. 考查非谓语动词。此处use为现在分词作方式状语，表示“可以通过声音或光线来发送”，故填using。 考查连词。结合前后文语境可知为并列关系，用连词and。故填and。 using and For languages not 8____________ (write) with the Latin alphabet, other versions of Morse code are used.The Chinese telegraph code is used to change Chinese 9____________(character) into four-digit (四位数) codes and then those digits are sent through standard Morse code. 考查非谓语动词。此处languages与write构成被动关系，故用过去分词作定语。故填written。 考查名词的数。此处character(汉字)应用复数形式。故填characters。 written characters 10____________(similar), Korean Morse code uses the SKATS (Standard Korean Alphabet Transliteration System) to allow Korean to be typed on Western typewriters. 【语篇解读】　本文是一篇说明文。文章介绍了摩斯密码的相关情况。 考查副词。修饰后文句子用副词similarly，首字母大写。故填Similarly。 Similarly 谢 谢 观 看 WELCOME UNIT $
