Goverments worldwide are increasingly asserting their digital sovereignty,aiming to regulate online activities that occur within their geographical limits.This often involves data localization laws,which require data about their citizens to be stored on servers within the county.China,for instance,has long implemented stict internet regulations,often referred to as the "Great Firewall,"to control information flows and maintain social stability.Similarly,the European Union's General Data Protection Regulation (GDPR)represents a powerful assertion of digital sovereignty,granting individuals greater control over their personal data and imposing stringent rules on any organization that processes it,regardless of where that organization is based. Conversely,advocates for a free and open intemet argue that these assertions of sovereignty threaten the very fabric of the global network.They contend that balkanizing the internet into distinct national segments undermines its potential as a tool for global communication,commerce,and the free exchange of ideas.The principle of a"global commons,"they argue,should prevail,with multinational govemance models,rather than unilateral national laws,guiding the digital sphere.For them,the intemnet is a frontier without borders,a space where ideas flow freely,unconstrained by the politics of geography. This tension creates a complex landscape.The rise of cybercrime,the spread of disinformation,and foreign interference in elections have made the case for some form ofregulation compelling.Yet,heavy- handed govemance can stifle innovation and be weaponized to suppress dissent.Finding a balance between protecting national interests and preserving the open,innovative spirit of the internet is one of the defining geopolitical challenges of our time.The outcome of this struggle will determine not just the future of the internet,but the nature of power and governance in the 21st century. ()1.What is the main issue discussed in the passage? A.The history of internet development. B.The conflict between national sovereignty and a global internet.

()4.Why do advocates for a free intemet oppose strong assertions of digital sovereignty? A.They believe the internet should be governed by a single world government. B.They think it will hinder the internet's potential for global communication and innovation. C.They argue that national laws are always more effective than international ones D.They fear that it will lead to increased cybercrime. ()5.The author's attitude towards the issue can be best described as: A.Strongly in favor of digital sovereignty. B.Strongly in favor of a completely free internet. C.Neutral and analytical,outlining a complex problem. D.Critical of all forms of internet regulation. Passage B For decades,the debate about artificial intelligence(AD has oscillated between utopian promises of a problem-solving savior and dystopian fears of a job-destroying overlord.While both narratives contain grains of truth,the reality is far more nuanced and immediate:AI is not a future event but a present technology that is quietly,and often invisibly,reshaping the very structure of the internet as we know it. Its most profound impact is on the lifeblood of the online world:information. Traditional internet search engines operated on a fundamentally linear,keyword-based model.A user types in a query,and the engine retieves and ranks web pages based on relevance signals like the frequency and placement of those keywords.This system,while revolutionary for its time,was often clumsy and easily manipulated through techniques like keyword stuffing.Al,particularly through machine leamning and natural language processing,has revolutionized this process.Modemn search algorithms can now understand the intent behind a query,not just the literal words.They can discern that asking best place for pizza near me"is different from how to make pizza dough at home,"and deliver results accordingly.This is the era of semantic search,where the goal is to understand context,concepts, and user history. Beyond search,AI is the engine driving the personalized intemnet.Every time you scroll through a social media feed,watch recommended videos on YouTube,or see targeted advertisements,you are interacting with an AI system.These algorithms analyze your past behavior-what you clicked,what you watched, what you liked-to predict what you might be interested in next.This has created an incredibly efficient and engaging online experience.However,it has also given rise to"filter bubbles"and "echo chambers," where users are primarily exposed to information that reinforces their existing beliefs,limiting their exposure to diverse perspectives. Furthermore,AI is becoming a powerful tool for content creation,bluring the lines between human and machine-generated information.AI can now write news articles,compose music,and even generate realistic-looking images and videos (so-called"deepfakes").While these tools have immense creative potential,they also present a formidable challenge in an era already plagued by disinformation.The ability to cheaply and quickly produce convincing fake content threatens to erode public trust in all online information,forcing us to question the very authenticity of what we see,read,and hear. ()1.What is the main argument of the first paragraph? A.AI is a future threat that will destroy jobs. B.The debate about AI is irelevant to the modern intemnet. C.AI is already having a tangible and significant impact on the internet. D.Utopian and dystopian views ofAI are completely accurate. ()2.How has AI changed the way search engines work,according to the passage? A.It has made them rely more heavily on keyword matching. B.It has enabled them to understand the user's true intention. C.It has made them slower and less efficient D.It has eliminated the need for user queries. ()3.The term"filter bubbles"(paragraph 3)refers to a situation where intemet users: A.Are exposed to a wide variety of information. B.Are prevented from accessing harmful content by filters. C.Are mainly shown information that aligns with their existing views. D.Use software to block advertisements. ()4.What challenge does AI-powered content creation,especially"deepfakes",pose? A.It makes it harder for artists and musicians to be creative. B.It undermines public trust in the authenticity of online information. C.It is too expensive for most people to use. D.It causes search engines to stop working properly ()5.The author's primary purpose in writing this passage is to: A.Praise the wonderful achievements ofAI. B.Warn people about the dangers of deepfakes. C.Provide a balanced overview ofAI's current influence on the internet. D.Argue that the internet should not be personalized. 二、完形填空 Navigating the vast landscape of the intemnet can be both exhilarating and perilous.While it offers unprecedented access to information and global connection,it also presents unique challenges, particularly for the younger generation who have grown up in this world.As digital(1) they are "native speakers"of the digital language of computers,social media,and apps.However,fluency does not automatically equate to(2) The internet's most powerful appeal lies in its ability to (3) geographical and social frontiers.A teenager in a small town can access the same learning resources as a student in a major city.They can connect with peers from across the globe,(4) their understanding of different cultures.This(5) to information and people is a tremendous advantage.Yet,this same openness also exposes them to risks.The anonymity of the online world can(6) cyberbullying,where individuals are targeted and harassed behind a screen.The immense pressure to present a perfect,curated life on social media often leads to anxiety and a distorted sense of (7) To a certain(⑧) the solution lies not in strict censorship,which is often counterproductive,but in(9) digital literacy.This goes far beyond just knowing how to use a device.It involves teaching young people to critically evaluate the information they (10) They must leamn to distinguish between a credible news source and a piece of misinformation.They need to understand the implications of their digital footprint and how their data is being(11) They must also develop the social and emotional skills to handle online relationships (12) In essence,we must(13) young people with the tools to be not just digital natives,but digital citizens.A digital citizen is aware of their rights and responsibilities online.They use the internet to create, to advocate for change,and to learn,rather than just to consume.The goal is to empower them to (14) the vast resources of the Internet(15) navigating its hazards safely and ethically 1.A.immigrants B.visitors C.natives D.pioneers 2.A.wisdom B.speed C.popularity D.fluency 3.A.protect B.cross C.defend D.ignore 4.A.limiting B.narrowing C.widening D.questioning 5.A.response B.access C.barrier D.attitude 6.A.prevent B.stop C.encourage D.foster 7.A.reality B.humor C.direction D.humor 8.A.extent B.exception C.effect D.effort 9.A.promoting B.preventing C.reducing D.ignoring 10.A.deliver B.create C.encounter D.forget 11.A.collected B.used C.delivered D.taken 12.A.dangerously B.rarely C.carelessly D.responsibly 13.A.equip B.help C.deliver D.bring 14.A.give up B.take off C.bring up D.hamness 15.A.after B.while C.unless D.before 三、阅读短文回答问题 Read the following passage and answer the five questions that follow. The concept of the"digital divide"has evolved significantly since the term first gained prominence in the 1990s.Initially,it referred to a simple binary:those who had physical access to a computer and the intemet,and those who did not.This"first-level"digital divide was largely a matter of infrastructure and economics.Governments worldwide launched initiatives to wire schools and libraries,aiming to bridge this gap by providing the hardware and connectivity necessary to get online. Today,while significant disparities in physical access still exist globally,particularly between developed and developing nations,the discourse has shifted.Attention has turned to a more nuanced and perhaps more insidious"second-level"digital divide.This divide is not about whether people can get online,but how they use the internet once they are connected.Research has consistently shown that users from higher socio-economic backgrounds tend to engage in "capital-enhancing"activities online.They use the intemnet for job searches,online courses,distance leaming,accessing government services,managing finances,and seeking out information for self-improvement.For these groups,the intemnet is a tool for advancement In contrast,users from lower socio-economic backgrounds,even when they have access,are more likely to engage in what are called "recreational"or"social"activities.Their online time is often dominated by social networking,playing online games,watching entertainment videos,and casual browsing.While these activities are not without value,they do not offer the same potential for social mobility or skill acquisition as capital-enhancing activities.The reasons for this "usage gap"are complex.They may stem from a lack of digital literacy,fewer role models who demonstrate productive online habits,or simply the pressure of time and energy in the face of other economic hardships This new understanding has profound implications for education and policy.Simply providing a device and a connection is no longer enough.The challenge now is to actively cultivate the skills and motivation necessary for effective and purposeful internet use.It requires teaching critical digital literacy skills from a young age,not just how to use a word processor,but how to evaluate a source,build a professional network online,and leverage digital tools for learning and career development.Until the second-level digital divide is addressed,the internet,for all its promise,risks becoming another force that reinforces, rather than reduces,existing social inequalities. 1.According to the passage,what is the main difference between the"first-level"and"second-level" digital divides as explained in the passage? 2.According to the passage,what kind of online activities do users from higher socio-economic backgrounds tend to perform?Give two examples. 3.Why does the author say that simply providing access to the internet is"no longer enough"(paragraph 4)2 4.What specific skill does the author suggest teaching young people to help bridge the second-level digital divide? 5.In the author's opinion,what is a potential negative consequence ofignoring the second-level digital divide? 四、短文填空（词汇运用） 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。 The rise of the internet has fundamentally reshaped the landscape of modern commerce.E-commerce, once a (1) concept,is now a daily reality for billions.Its(2) has democratized trade, allowing small businesses to compete on a global stage.Yet,this new era of(3) brings with it both unprecedented opportunities and significant challenges To a large (4) _consumers have come to expect convenience.The ability to (5) goods to one's doorstep with a single click has(6)off dramatically,changing our shopping habits forever.However,this shift has also given rise to new concems.The (7) of online transactions require the sharing of personal data,which must be managed(8) Data security and privacy have become major (9) for both individuals and governments Furthermore,(10) the sheer volume ofinformation available online can be overwhelming.It is crucial to learn how to (11) up reliable sources and not fall prey to misinformation.The digital world,while breaking down old (12) ,has created new ones of access and literacy.The challenge for the future is to ensure that the benefits of this connected world are shared(13) Ultimately,navigating this complex online environment(14)a new set of skills.We must learn to be not just consumers of digital content,but critical and ethical participants in an ever-evolving virtual society,(15) its power for personal and collective growth. 2. 4. 6. 7. 8 9. 10. 11 12. 13. 14. 15. 五、写作 假设你是李华，你的英国笔友Tom来信说，他发现他的很多同学都沉迷于社交媒体，花费大量 时间进行线上互动，却忽视了现实生活中的学习和人际关系。他对此感到担忧，想听听你的看 法。请你给他回一封邮件。 内容包括： 1.分析导致青少年沉迷社交媒体的原因（至少两点）。 2.说明过度使用社交媒体的负面影响（至少两点）。 3.提出一些健康使用网络的建议。 注意： 1.词数80左右； 2.可以适当增加细节，以使行文连贯： 3.邮件的开头和结尾已为你写好，不计入总词数。 Dear Tom I was sorry to hear about your concern regarding your classmates'addiction to social media.It's a problem many teenagers face in today's digital age. In my view,this addiction stems from the fear of missing out(FOMO)and the instant appeal of likes and comments,which provide a false sense of popularity and validation.The consequences,however,are serious.Excessive use not only distracts from studies but also weakens real-life communication skills, leading to loneliness and anxiety. I suggest we set daily screen time limits and prioritize face-to-face interactions.It's also crucial to use social media as a tool for learning and connecting,rather than just for passive scrolling Yours, Li Hua 参考答案 PassageA:1.B 2.C3.C4.B 5.C 阅读理解 Passage B:6.C 7.B8.C9.B 10.C 二、完形填空1.C2.A3.B4.C5.B6.D7.A8.A9.A10.C11.A12.D13.A14.D15.B 1.The first-level digital divide is about physical access to the internet,while the second- level digital divide is about the quality and purpose of intemnet usage (how people use it). 2.They tend to perform"capital-enhancing"activities.Examples include:job searches, online courses,distance learning,accessing government services,managing finances, and seeking information for self-improvement.(Any two) 三、阅读短文 3.Because even with access,users from lower socio-economic backgrounds may lack 回答问题 the skills and motivation to use the internet for activities that enhance social mobility, leading to a"usage gap". 4.The author suggests teaching critical digital literacy skills,especially how to evaluate a source. 5.A potential negative consequence is that the internet will reinforce existing social inequalities rather than reduce them. 1.frontier 2.access 3.commerce 4.extent 5.deliver 6.taken 7.majority 8.responsibly 四、短文填空 9.affairs 10.obviously 11.bring 12.frontiers 13.equally 14.requires 15.using 五、写作 范文： Dear Tom, I was sory to hear about your concern regarding your classmates'addiction to social media.It's a problem many teenagers face in today's digital age.
