D 【考点】转折逻辑+指代衔接 【详解】首句陈述各州推行禁发短信法案及宣传活动的努力，后文却说美国人开车仍然在发信息，所以此处显然有转折关系。D项“Yet” 构成转折关系，“the problem” 指代首句驾驶时使用手机的现象，“appears to be getting worse” 统领后文“Americans continue texting...” 7. E 【考点】代词指代+承上启下 【详解】上面讲美国人开车使用手机和社交媒体导致事故不减反增，下段就在分析造成这样的原因，段首设空，很显然要承上启下。加上代词“That” 指代前句事故激增现象（road accidents... sharp increases）, “partly because” 解释造成这样现象的部分原因。 8. B 【考点】主旨概括+承上启下 【详解】本篇文章的语篇结构是分析现象，阐述原因再呈现解决方法。本段是针对上文提到的现象和原因讨论可行的方法。“Big change” 指代根除分心驾驶的终极目标，“big ideas”预示后文革命性方案（treat like drunk driving）, 该选项起到承上启下作用：上承问题诊断（distraction increasing）, 下启解决方法（technological enforcement）。 9. G 【考点】概括总结 【详解】本段主要讲具体的解决方法，通过科技手段即能检测事故司机开车时是否有不当的操作如发信息，看社交软件等。“Thus” 表明结论关系，“it” 指代Textalyzer设备，“digital witness” 比喻性总结其工作原理（check operating system），“illegal phone usage during driving” 复现原文“not allowed under hands-free laws”. 10. C 【考点】语篇逻辑+代词指代 【详解】前文讲到“We need something on the books that can change people’s behavior.”我们需要一些书上的东西来改变人们的行为。设空后文提到“He believes this approach would make drivers....”他相信这种方法能使司机... 显然设空处要填一种方法再结合本段首句需要书上的内容来改变人们的行为可知这个方法是立法。 三、完形填空。 11-15 ABADC  16-20 BDADB    21-25 CACBD 【解析】这是一篇记叙文。Roth是一名森林护林员，下雨后森林就容易患病并导致其他健康树木被传染，于是他使用无人机和AI帮助他快速地找到染病的树木并及时清理，使得他的护林工作在人员不足的情况下得以进行。 11. A 本题考查词义辨析。句意：他最初的使命是为后代保护树林。此处要表达最初的使命 initial 符合题意。B. main（主要的）、C. final（最终的）、D. temporary（临时的）不符合语境。 12. B 本题考查形容词辨析。句意：现在，气候变化迫使他要计划一个不确定的未来。这表明气候变化带来了严重的灾害管理，因此是充满变数和未知的。B. uncertain（不确定的）符合题意。 A. exciting（令人兴奋的）、C. optimistic（乐观的）与“disaster management”的负面基调矛盾。D. imaginary（想象的）不符合现实背景。 13. A  本题考查动词辨析。句意：森林作为试验场的事情使他获得了“数字护林员”的绰号。 B. costing（使付出代价）C. demanding（要求）、D. refusing（拒绝）均不符合语境。 14. D 本题考查动词辨析。句意：在暴风雨后，损坏的树木必须及时清除，为了防止甲虫在死树中繁殖并破坏森林，受损的树木必须被处理掉。A. preserved（保护）、B. examined（检查）、C. planted（种植）均不符合题意。 15. C 本题考查短语用法。句意：之前，Roth 需要两个半小时来检查一亩的树林。A. by car（开车）、B. by air（乘飞机）、D. by boat（乘船）这几种交通方式检查一亩树林都不可能需要两个半小时。 16. B 本题考查动词辨析。句意：所以他可以快速定位受损的树木。前文说暴风雨后需要快速移除受损树木，现在无人机让他能在几天内扫描3000英亩。要移除就得先找到它们的位置，B. locate（定位，找到位置）符合题意。A. count（计数）不是目的；C. protect（保护）与移除矛盾；D. identify（识别/确认）先找到再确认。 17. D  本题考查名词辨析。句意：通知土地的主人。Roth是森林护林员(ranger)，负责管理森林，根据of the land 可知是要通知土地的主人即owners（所有者）A. ranger(护林员) B. colleagues（同事）、C. fellows（同伴/家伙）。 18. A 本题考查动词辨析。句意：Roth 的创新不仅于此，他还把照相机和AI结合起来。B. equipping不对，不是用照相机装备AI。C. providing（提供）不符合语境。D. comparing（比较）意思不相关。 19. D  本题考查动词辨析。句意：摄像头的主要功能是“看”和“识别”。A. Destroy（破坏）、B. ignore（忽略）意思完全错误。C. notice（注意到）强调主观上的注意，而AI识别物种是客观的技术动作。D. sees（看见）在这里引申为“识别出”或“检测到”，即通过摄像头“看到”并识别树种。 20. B 本题考查上下文语境。句意：树木的品种不能抵抗高温和干旱。因为气温升高和干旱是负面条件，树木无法抵抗这些恶劣条件。Resist 符合题意。A. help（帮助）、C. assist（协助）意思相反。D. prefer（更喜欢）不合逻辑。 21. C 本题上下文语境。句意：使用电子系统来跟踪它们的成长。他种植新物种是为了试验，因此需要监测它们的生长情况以评估适应性。A. accelerate（加速）、B. limit（限制）与试验目的相悖、D. enhance（增强）是主动干预促进生长，但文中未提及此目的。C. track（追踪，监测）符合试验中观察和记录生长过程的需求。 22. A 本题考查动词辨析和语境。句意：森林扩大，人手有限，难以对所有需要干预的情况做出及时反应或处理。“Interventions”指需要人为干预的措施（如处理病虫害、火灾等）。A. meet（遇见/应对）符合题意。B. face（面对）只表达了遭遇，未体现“应对/处理”的困难。D. admire（钦佩）意思完全不符。C. predict（预测）也不符合语境。 23. C 本题考查上下文逻辑。句意：没有记录，知识当然会怎么样。A. shared（共享）、B. expanded（扩展）意思相反。D. proven（被证明）与上下文无关。C. lost（丢失）直接对应“Without”的后果。 24. B  本题考查名词和语境。句意：Roth森林管理方面所积累的专业知识和技能被追捧，同事向他请教，他还去大学讲座。expertise（专业知识，专业技能）符合语境。A. tradition（传统）与“tech-driven”矛盾。C. hobby（爱好）。D. failure（失败）。 25. D 本题考查逻辑关系。句意：然而，科技不能替代在森林中行走。前句讲他的科技专长很受欢迎（科技应用的成功），后句他坚持认为“实地核查至关重要”。两者之间是明显的转折关系，强调科技的局限性。D. However（然而）符合题意。A. Instead（反而）表示替代方案。B. Moreover（而且）表示递进。C. Therefore（因此）表示结果。 Book 4 Unit 2 课时三 写作技能训练 一、写句子。 1. “I think it is the payment for the Jobo ,” Jane answered. The two girls were lost in thought, with their eyes staring at the envelope. 2. Suddenly，they found the envelope cracked, and there was a chink, through which they found no money. It seemed that things became more confusing. 3. It wasn’t long before they returned and gave the envelope to the older woman, nervousness and curiosity overwhelming them. 4. Getting closer to those papers, they surprisingly found that they were the paintings from the three little kids! 5. Not until then did they realize that the payment was not money. So ashamed were they that they stood there clumsily, feeling the blood rushing to their faces. 6. The unforgettable experience gave them a lesson that we shouldn’t judge others by their appearance because a warm heart might hide through a hard face. 二、写语篇。 7. Worried, the two girls discussed what was in the envelope as they returned. “I think it is the payment for the Jobo ,” Jane answered. The two girls were lost in thought, with their eyes staring at the envelope. Staring at the envelope for so long, they suddenly found the envelope cracked, and there was a chink, through which they found no money. It seemed that things became more confusing. Hence, they sped up towards the old lady’s home, intending to deliver the payment and wondering whether they could get their favorite jobos. It wasn’t long before they returned and gave the envelope to the older woman, nervousness and curiosity overwhelming them. The lady opened the envelope, took out a pile of papers, and smiled. Getting closer to those papers, they surprisingly found that they were the paintings from the three little kids! Not until then did they realize that the payment was not money. So ashamed were they that they stood there clumsily, feeling the blood rushing to their faces. The old lady thanked them and took out another two baskets of jobs. Their favorite jobs in the old lady’s hands were in contrast to the cold impression on her. The unforgettable experience gave them a lesson that we shouldn’t judge others by their appearance because a warm heart might hide through a hard face. Book 4 Unit 2 单元过关答案 一、阅读理解 体裁：说明文 题材：ChatGPT对学生的影响。 【文章大意】研究使用ChatGPT学生记忆力更差，实验发现使用ChatGPT写文章的学生记不住自己写的东西，大脑活动也相应比自己动手写的学生更少。 1 .答案：B 【命题意图】细节理解题。 【详解】文章第二段明确提到“As more and more students use AI to help with schoolwork, we still aren’t sure about the effect it’s having on learning. To look into this, researchers... asked 54 people... to write three 20-minute essays”。其中“To look into this”中的“this”指代前文的“the effect it’s having on learning”（AI对学习的影响），因此研究目的是探究AI对学习的影响，与选项B一致。 2 .答案：B 【命题意图】细节理解题。 【详解】第三段最后一句明确说明“Participants were required to wear headsets to record their brains’ electrical activity while they wrote”，即通过headset记录大脑电活动来衡量认知参与度，与选项B完全匹配。 3 .答案：D 【命题意图】词义猜测。 【详解】第四段后文具体描述了三组结果的差异：“Those using ChatGPT showed the lowest levels of brain connectivity... Those using only the internet had greater brain connectivity. Those using no external sources had the most connectivity”，即三组的大脑连接水平不同。因此“discrepant”意为“不同的”，与选项D一致。 4 .答案：C 【命题意图】细节理解。 【详解】第五段提到后续测试中“those who had used ChatGPT before still showed weaker brain connectivity even now that they were writing without using any external sources”，即使不使用外部工具，之前用ChatGPT的人仍表现出较弱的大脑连接，这是最值得关注的发现，与选项C一致。 5 .答案：C 【命题意图】推理判断。 【详解】最后一段指出“the authors decided their work should be published without waiting for peer review because of how important the findings may be for children’s education — and they felt the results should be seen as soon as possible”，即研究结果对儿童教育很重要，希望尽快公布以应用于教育领域，与选项C一致。 体裁：说明文 题材：网络文学的发展。 【文章大意】中国网络文学成为Z世代主要阅读内容，英国图书馆与阅文集团合作推动文化交流，收录多部中国网络小说。AI技术助力海外市场拓展，网络文学IP衍生多元化商业产品，展现全球叙事潜力。 6 .答案：B 【命题意图】细节理解题。 【详解】根据第二段中 “enhance culturalexchange and co-create new cultural IP” 可知，合作目标是加强文化交流，共同打造新文化IP，与选项B “促进全球文化合作”完全一致。 故选B项。 7 .答案：B 【命题意图】细节理解题。 【详解】根据第四段中 “accelerates translationand reduces costs” 可知，AI技术加速翻译并降低成本，对应选项B中“更快、更便宜的传播”。 故选B项。 8 .答案：C 【命题意图】推理判断题。 【详解】文章第五段以My Vampire System为例，说明IP如何被改编为 shows、comics、audiobooks 等多种形式，体现跨媒介改编的成功，故选C项。 9 .答案：D 【命题意图】推理判断题。 【详解】文章结尾使用 “immense potential forfuture growth”（巨大增长潜力）、driving force（推动力）等词，明确表达乐观态度，A. objective: 客观的、 B. conservative:保守的、C: indifferent:冷漠的。故选D项。 二、语篇结构 10. D 【考点】考查段落主旨与转折逻辑。 【详解】根据上文“It’s no secret that many people are addicted to their smartphones”（许多人沉迷智能手机已是公开秘密）引出话题，下文“We already know about issues...”（我们已知“科技颈”等问题）开始讨论具体身体损伤。D选项“But do you know the damage it does to your body”（但你知道它对身体的伤害吗）通过转折词but自然衔接, 其中“it”指代上文的“smartphone”，“damage”精准呼应下文的“"issues like tech neck”。 11. E 【考点】考查代词和逻辑结构 【详解】根据上文“The dent happens when people rest their phone on the pinky finger for support”（压痕因小指支撑手机产生）描述现象，下文“And the mark is temporary”（痕迹是暂时的）给出结论。通过mark 前面的the 可知是特指前面的dent。 “smartphone pinky” isn’t anything to be alarmed about”也说明智能小拇指并不是个需要担心的医学问题。E选项“Yet phones aren’t heavy enough to harm blood flow”（但手机不够重到伤害血流）通过转折词“Yet”解释原因：重量不足不会阻止血液流通所以没有什么医学危害。 12. C 【考点】考查句际顺承与主旨大意。 【详解】根据下文“It is probably a good sign”（这可能是好迹象）中“it”指代小指压痕，根据上文可知压痕并不是一个需要担心的健康问题，且转折词“probably”暗示压痕虽无害但有警示作用。C选项“Medical experts say this isn’t a true health danger”（医学专家称这不是真正的健康危险）。 13. G 【考点】考查句际顺承与逻辑结构。 【详解】根据上文“At first, it makes the thumb joints too loose”（最初使拇指关节过度松弛）描述短期影响，通过at first （首先）说明这里在短期和长期G选项“Over time, this constant movement can permanently damage the finger joints”（长期持续运动会永久损伤指关节）通过时间对比词“Over time”（对比At first）引出长期后果。其中“this constant movement”指代上文“regular phone use”（常规手机使用）短期关节松弛久之就会长期永久损伤。 14. F 【考点】考查概括总结。 【详解】根据上文“Simply holding your phone puts stress on your hand muscles”（单纯握持手机已造成肌肉压力），下文“it strains the inside muscles”（它使内部肌肉紧张）描述手机对小指产生的压力，以及厂家把手机越做越大，最后总结：要时不时让手休息一会儿。 三、语法填空。 15. innovative考查形容词作定语。空格位于名词短语 “train” 之前，需形容词修饰名词。动词 “innovate” 的形容词形式为 “innovative”（创新的），描述列车的创新特性，符合语境。故填 innovative。 16. featuring 考查现在分词作伴随状语。空格位于逗号后，与主句 “Berths will be tailored...” 形成逻辑伴随关系。动词 “feature”（以...为特色）与主语 “Berths” 为主动关系，故用现在分词形式 featuring。 17. automatically 考查副词作状语。空格修饰动词 “work”，需副词形式。形容词 “automatic” 的副词形式为“automatically”（自动地），描述按钮的工作方式。故填 automatically。 18 . whose 考查定语从句。 空格位于名词短语 “professional medical staff”后，逗号隔开，引导非限制性定语从句：______ presence improves service efficiency。从句缺定语修饰名词 “presence”（服务效率的提高依赖于 “他们的存在”），先行词为 “carers and professional medical staff”，故填whose. 19. are encouraged 考查谓语动词。主语 “companies” 与动词 “encourage” 构成被动关系（企业被鼓励），且全文为一般现在时。故填 are encouraged。 20. released 考查过去分词作后置定语。空格修饰名词“plans”，动词 “release”与“plans” 为被动关系（计划被政府发布），故用过去分词 released。 21. it 考查it做形式宾语。 固定结构 “make + it + adj. + for sb. to do”，其中 “it” 作形式宾语，真正宾语是“for elderly visitors to access them”。故填 it。 22. joining考查固定搭配。 prefer doing A to doing B 宁愿做某事而不愿做某事。“prefer traveling... to ______” 中，空格需与“traveling” 形式平行，且介词 “to” 后接动名词。故填 joining。 23.

Maybe she was ten; I didn’t know her age. What I did know was that the child-size wheelchair converted my feeling-sorry-for-myself emotion into compassion for a child whose burden was far heavier than mine. My lesson wasn’t over. The little girl seemed to be pleading with the lady, who must be her mother. She wanted to walk like the other kids, but she needed to use her crutches, too. I watched as the small girl pushed herself from the wheelchair into a standing position. When she did, it was obvious that the courageous child had only one leg. Fighting back tears, I circled the block to make sure that what I had observed was real. There she was again, struggling with crutches, with her head held high. I truly believe that this girl was saying, “Be strong.” I had a choice to make. I could push through self-pity and choose to live my life positively and be thankful for what I could do, or I could be forever miserable, contemplating what I couldn’t. 学科网（北京）股份有限公司 $ Book 4 Unit 2 课时一 词汇、语法考点化训练 一、根据提示，写出单词的正确形式。 1.

Book 4 Unit 2 课时二 阅读技能训练 一、阅读理解 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 【2023年浙江1月C篇】 A machine can now not only beat you at chess, it can also outperform you in debate. Last week, in a public debate in San Francisco, a software program called Project Debater beat its human opponents, including Noa Ovadia, Israel’s former national debating champion. Brilliant though it is, Project Debater has some weaknesses. It takes sentences from its library of documents and prebuilt arguments and strings them together. This can lead to the kinds of errors no human would make. Such wrinkles will no doubt be ironed out, yet they also point to a fundamental problem. As Kristian Hammond, professor of electrical engineering and computer science at Northwestern University, put it: “There’s never a stage at which the system knows what it’s talking about.” What Hammond is referring to is the question of meaning, and meaning is central to what distinguishes the least intelligent of humans from the most intelligent of machines. A computer works with symbols. Its program specifies a set of rules to transform one string of symbols into another. But it does not specify what those symbols mean. Indeed, to a computer, meaning is irrelevant. Humans, in thinking, talking, reading and writing, also work with symbols. But for humans, meaning is everything. When we communicate, we communicate meaning. What matters is not just the outside of a string of symbols, but the inside too, not just how they are arranged but what they mean. Meaning emerges through a process of social interaction, not of computation, interaction that shapes the content of the symbols in our heads. The rules that assign meaning lie not just inside our heads, but also outside, in society, in social memory, social conventions and social relations. It is this that distinguishes humans from machines. And that’s why, however astonishing Project Debater may seem, the tradition that began with Socrates and Confucius will not end with artificial intelligence. 1. Why does the author mention Noa Ovadia in the first paragraph? A. To explain the use of a software program. B. To show the cleverness of Project Debater. C. To introduce the designer of Project Debater. D. To emphasize the fairness of the competition. 2. What does the underlined word “wrinkles” in paragraph 2 refer to? A. Arguments. B. Doubts. C. Errors. D. Differences. 3. What is Project Debater unable to do according to Hammond? A. Create rules. B. Comprehend meaning. C. Talk fluently. D. Identify difficult words. 4. What can we learn from the last paragraph? A. Social interaction is key to understanding symbols. B. The human brain has potential yet to be developed. C. Ancient philosophers set good examples for debaters. D. Artificial intelligence ensures humans a bright future. 5. What’s the purpose of the author’s writing the passage? A. To praise AI’s debating achievements. B. To predict AI’s dominance in debates. C. To explain how machines process symbols. D.

Americans continue texting, using social media, and taking photos while driving. Consequently, road accidents have reversed previous declines with sharp increases. 7 . National Highway Traffic Safety Administration chief Mark Rosekind acknowledges increased driving contributes to this trend, but stresses distraction itself is “only increasing, unfortunately”. 8 . So to try to change a distinctly modern behavior, lawmakers and public health experts are reaching back to an old approach: They want to treat distracted driving like drunk driving technological enforcement. An idea from lawmakers in New York is to give police officers a new device called the Textalyzer. When an officer arrives at the scene of a crash, they can use the Textalyzer to check the operating system for recent activity. The technology could determine whether a driver had just texted, emailed or done anything else that is not allowed under New York’s hands-free driving laws. 9 . We need something on the books that can change people’s behavior. Felix W. Ortiz, who championed New York’s 2001 handheld ban, insists: “We need tools to change behavior.” 10 , he believes this approach would make drivers “more afraid to use phones,” potentially achieving what fines alone cannot. A. If the book came into effect B. Big change requires big ideas C. If the Textalyzer bill becomes law D. Yet the problem appears to be getting worse E. That is partly because people are driving more F. However, public campaigns show decreased effectiveness over time G. Thus, it serves as a digital witness to illegal phone usage while driving 三、完形填空。 阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 【2025.广州一模B篇改编】 Martin Roth became a forest ranger in the 1980s.

Jobos were their favorite fruit, but the tree belonged to a lady who lived in the house by the hill. They heard she was difficult, but that sometimes she would give fruit in return for an errand（差使）. The girls finally gathered their courage to knock on her door. An elderly woman with a fierce look answered, staring down at the girls. “We heard.” said Sandy, her voice shaky, “that you give jobos in payment for running an errand.” The lady raised one eyebrow, then went into the kitchen and took two baskets. She pushed them into the girls’ hands. “Go fill these with jobos, and come right back.” The girls raced up the hill to the tree and filled the baskets with the ripest jobos. Back at the house, the lady filled a bag with rice and handed it to Sandy. “Take this bag and one basket of jobos to the Brown family. And ask them for the payment,” the lady added with a tight smile. “If you return without the payment, you won’t get the fruit.” The girls struggled all the way with the bag and the basket. When they got there, Mrs. Brown answered the door. Inside on the floor were three little children, each painting something on paper. Mr. Brown was lying sick in bed. Times were hard. The girls handed her the food. “This is from the lady with the jobo tree,” said Sandy. “She asked for the payment, too.” Jane said awkwardly. The payment! The payment!” The children repeated, waving the paper in their hands happily. Sandy and Jane looked at each other strangely. With a smile, Mrs. Brown handed Sandy a large sealed（密封的）envelope so full that it was almost starting to break open. The girls said goodbye and left quickly. “I wonder,” Sandy murmured, “whether Mrs. Brown can afford to pay for that food.” Worried, the two girls discussed what was in the envelope as they walked back. —————————————————————————————————————————————————————————————————————————————————————— The lady opened the envelope, took out a pile of papers, and smiled. —————————————————————————————————————————————————————————————————————————————————————— 第一步：分析段首句，确定续写方向（预测情节，问题引领） 根据第一段首每内容Worried, the two girls discussed what was in the envelope as they walked back（两个女孩忧心忡忡，一边往回走，一边讨论信封里的东西）可设问如下： 1.

Scientists also reveal that those who had used ChatGPT before shows weaker brain connectivity when doing assigned tasks without using any external help. As more and more students use AI to help with schoolwork, we still aren’t sure about the effect it’s having on learning.To look into this, researchers from the Massachusetts Institute of Technology asked 54 people aged 18 to 39 to write three 20-minute essays. In the study, the people were divided into three groups. One group wrote all three essays with the help of popular AI chatbot ChatGPT. Another group used only the Internet for help, with AI responses disabled. And a third group used no external sources at all. The essays were on moral or philosophical topics, like whether we need to help others in order to be truly happy, or whether books and movies can truly change people’s lives. Participants were required to wear headsets to record their brains’ electrical activity while they wrote. The results among those participants are discrepant. Those using ChatGPT showed the lowest levels of brain connectivity in their brains, while those using only the internet had greater brain connectivity. Those using no external sources had the most connectivity. After they’d finished, the ChatGPT group was also the least able to quote sentences from their essays. Eighteen participants were later called back to rewrite one of their essays. This time the groups were switched — those who had used ChatGPT before now had to write with no external sources, and those who had previously used no external sources could now use ChatGPT. It was found that all nine participants from the no-external-sources group could remember all the topics they had written about before. But only three of those who had used ChatGPT could remember all of their topics. And those who had used ChatGPT before still showed weaker brain connectivity even now that they were writing without using any external sources. The study has not yet been peer reviewed. However, the authors decided their work should be published without waiting for peer review because of how important the findings may be for children’s education — and they felt the results should be seen as soon as possible. 1. What’s the purpose of the study? A. To observe students’ reliance on AI. B. To find out the effect of AI on learning. C. To test the efficiency of AI on homework. D. To check the connectivity between AI and the brain. 2. How did researchers measure cognitive engagement? A. By varying topics among participants. B. By using headsets to track brain activity. C. By comparing essay quality across groups. D. By testing participants’ philosophical knowledge. 3. What does the underlined word “discrepant” mean in paragraph 4? A. Significant. B. hopeful. C. Doubtful. D. Different. 4. What was the most concerning finding in follow-up tests? A. Unaided writers forgot most content over time. B. ChatGPT users demonstrated poor writing skills C. ChatGPT users performed weaker brain activity. D. Internet researchers showed weaker memory recall. 5. Why are researchers eager to publish the study? A. They want to secure patent rights for their study. B. They need to meet the requirements of the participants. C. They hope to apply potential influences to education. D. They intend to protect the results of the study from being copied. B Online literature has become the primary way for Gen Z readers to consume literature in China, with popular new novels appearing online first. This is where literature in the digital age sees some of the most rapid evolution. Recently, the British Library and Yuewen launched a three-year collaboration, Literature in the Digital Age, to enhance cultural exchange and co-create new cultural IP. As part of this partnership, the library added ten Chinese online novels to its collection, including Soul Land, The King’s Avatar, and Lord of Mysteries 2: Circle of Inevitability. These works, published online in the last decade, represent modern classics of Chinese digital literature. This follows the library’s 2022 inclusion of its first batch（一批）of Chinese online literature. The partnership highlights online literature’s global influence. In 2023, China’s online literature industry generated about 4.35 billion yuan overseas, according to industry reports. The sector’s overseas growth is fueled by AI technology, which accelerates translation and reduces costs. Generative AI tools streamline the once labor-intensive translation process, enabling the adaptation of Chinese content into various languages for global markets. As Internet literature gains such mainstream popularity, it fosters a thriving commercial market. IP from online novels appears in a range of media, from films to TV shows, animations, games, artwork, cosplay, and more. A typical example is My Vampire System, which has produced a massive online presence in shows, comics, audiobooks, lively discussion board threads, and translations into six languages. The story of online literature is only just beginning. As digital platforms lower barriers to global cultural exchange, online literature’s international expansion shows immense potential for future growth. Its blend of technology, creativity, and commercial adaptability positions it as a driving force in global storytelling. 6. What is the main purpose of the “Literature in the Digital Age” collaboration? A. To promote traditional Chinese literature. B. To promote global cultural collaboration. C. To increase sales of Chinese novels in the UK. D. To study the decline of traditional publishing. 7. How has AI technology impacted China’s online literature industry? A. It improves the quality of web novels. B. It enables faster and cheaper distribution. C. It crafts new storylines for foreign readers. D. It removes the need for human translators. 8. Why does the author mention My Vampire System? A. To emphasize the role of AI in translation. B. To compare Western and Chinese online literature. C. To illustrate the success of cross-media adaptations. D. To highlight the popularity of Western authors in China. 9. What’s the author’s attitude toward the future development of Chinese online literature? A. Objective. B. Conservative. C. Indifferent. D.

This is a small dent that appears on the little finger, and many people have shared pictures of it online. Hand expert Dr. Benson has studied this issue and said “smartphone pinky” isn’t anything to be alarmed about. He explains: “The dent happens when people rest their phone on the pinky finger(小指) for support. 11 And the mark is temporary, just like the mark you get from wearing glasses or a watch.” 12 It is probably a good sign. “If you see a clear dent on your finger, it probably means you're using your phone too much. This is a sign that you might be spending too much time online and not enough in the real world.” More importantly, other phone-related problems exist. Another serious problem is "texting thumb", which causes pain from constant scrolling and typing. Physical therapist Tim Allardyce says: “Regular phone use, especially messaging, makes your thumb work too hard. At first, it makes the thumb joints too loose 13 ” Simply holding your phone puts stress on your hand muscles. When you grip the phone between your thumb and pinky, it strains the inside muscles of your hand. The problem is getting worse as manufacturers are making many smartphones bigger, not smaller. 14 A.So, don’t use your hand to hold the phone. B.These repeated actions slowly weaken your joints. C. Medical experts say this isn’t a true health danger. D. But do you know the damage it does to your body? E. Yet phones aren’t heavy enough to harm blood flow. F. So it’s rather important to give your hands regular breaks. G. Then, this constant movement can permanently damage the finger joints. 三、语法填空 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。 Recently, a special train named “silver trains” has enjoyed increasing popularity among elderly people.

My heart sank. I had been stuck in bed nursing the aching knee, hoping and praying it wasn’t anything serious again. Unfortunately, it had never healed correctly following a previous surgery by another specialist. My geographically distant family members would sometimes call to offer medical advice or a pep talk, encouraging me to try harder to find a solution. I understood their good intentions, but following these conversations I would often cry for hours in frustration. I didn’t have any idea where else to look for answers. So, I learned to hide my circumstances. Thankfully, being able to write was my saving grace. I wrote columns for local newspapers and book anthologies, and even authored an inspirational novel. On social media, I posted smiling photos and avoided mentioning the health issues that would keep me housebound. I sincerely endeavored to stay positive, hold onto my faith, and trust that there would be a solution until the fated MRI’s report of the seriously reinjured knee on Christmas Eve. When this happened, I didn’t have any emotional or spiritual strength left in me to fight. By early March, the hopelessness increased. One desperate night, I tossed and turned, sobbing into my pillow until dawn. With my eyes swollen from lack of sleep and crying, I threw on my clothes, grabbed my crutches, and decided to take a drive to calm my troubled mind. That morning, it was blustery, cold, and dark. Thankfully, the coffee shop’s atmosphere was peaceful and inviting. Emptying the large cup, I headed back out to my car. By then, students who lived in the neighborhood were making their way to both the elementary and middle schools nearby. The youngsters chatted and laughed together while walking on the snow-covered sidewalk. 注意：续写词数应为150左右。 Then, I saw a little girl in a wheelchair with a woman pushing her. _________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ When she did, it was obvious that the courageous child had only one leg. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 学科网（北京）股份有限公司 $
