However,technology is not inherently detrimental to friendship.Video calling platforms have allowed families separated by geography to maintain bonds that would have weakened in previous generations. Online communities centered around niche interests-from rare book collecting to astrophysics-enable individuals to find kindred spirits they might never encounter in their immediate physical environment. For marginalized groups,particularly LGBTQ+youth in conservative areas,these digital spaces can provide lifelines of understanding and acceptance. The challenge,experts argue,lies not in the technology itself but in how we use it.Mindful consumption of social media,characterized by intentional engagement rather than passive scrolling,has been associated with better relationship outcomes.Setting boundaries-such as designating phone-free hours or prioritizing face-to-face meetings-can help preserve the depth that makes friendship valuable.As we navigate this digital landscape,the goal should be not to reject technology but to harness it in service of genuine human connection,ensuring that our online interactions enrich rather than replace the meaningful relationships that sustain us.

B.The number of online fiiends is inversely related to relationship quality. C.Social media platforms accurately reflect genuine friendships D.Most young adults prefer online fiiendships to real-life ones.

A.Strongly critical of its negative effects B.Completely optimistic about its benefits C.Balanced,recognizing both advantages and challenges D.Indifferent to the ongoing debate Passage B Artificial intelligence is revolutionizing how we interact with information,but its impact on critical thinking skills has become a growing concem among educators and cognitive scientists.A longitudinal study conducted across 15 American universities tracked students'analytical abilities from 2015 to 2024 revealing a 23%decline in skills related to evaluating source credibility and identifying logical fallacies. Researchers attribute this trend partly to the widespread adoption ofaI-powered search engines that provide direct answers without requiring users to navigate multiple sources. The phenomenon,termed "cognitive outsourcing,"occurs when individuals rely on algorithms to filter, interpret,and present information,bypassing the mental processes traditionally associated with learning Dr.Michael Torres,lead author of the study,explains:"When students can ask an AI assistant to summarize a complex text or generate a comparison between two historical events,they lose opportunities to practice synthesis and evaluation-skills that are fundamental to critical thinking." However,some experts argue that AI can be leveraged to enhance rather than diminish cognitive capabilities.Adaptive leaming platforms,for instance,use algorithms to identify students'weaknesses and provide targeted exercises that strengthen specific reasoning skills.In a pilot program at MIT,students using an AI tutor showed a 40%improvement in their ability to construct coherent arguments compared to those receiving traditional instruction.The key,according to proponents,lies in designing AI tools that challenge rather than replace human thinking The debate underscores a broader question about the future of education:Should we teach students to think like machines,or should we develop machines that think like humans?As AI becomes increasingly integrated into academic environments,striking a balance between efficiency and intellectual rigor remains paramount.The solution may not be to limit technology use but to redesign curricula that explicitly teach metacognitive strategies-helping students recognize when and how to engage their own reasoning rather than deferring to algorithms ()1.What does the longitudinal study primarily reveal about students'analytical abilities? A.They have remained stable over the past decade B.They have improved significantly with AI adoption. C.They have declined substantially in certain areas. D.They are now better at identifying logical fallacies. ()2.The term "cognitive outsourcing"in paragraph 2 refers to A.delegating thinking tasks to algorithms B.sharing cognitive load among group members C.using extemal resources to memorize facts D.outsourcing learning to tutors ()3.What is the main argument of AI proponents in paragraph 3? A.AI should replace traditional teaching methods entirely B.AI can be designed to strengthen critical thinking skills. C.AI tools are ineffective for improving reasoning abilities. D.AI limitations make it unsuitable for educational use. ()4.What does the author suggest as a potential solution to the problem? A.Limiting students'access to AI technology B.Returning to traditional teaching methods C.Teaching students to use their own reasoning consciously D.Developing AI that can completely replace human thinking 二、完形填空 For centuries,humans have sought ways to preserve knowledge and culture.From cave paintings to printed books,each technological advance has (1) how we store and share information.Now, digital technology is creating a revolution as (2) as any in history The Dunhuang Caves in China,which(3) over 1,000 years of Buddhist art,face a constant threat from natural erosion and human activity.Traditional conservation methods could only slow the(4) of these ancient treasures.However,modern technology has offered a(5) solution: high-resolution 3D scanning and digital modeling Working with international partners,Chinese researchers have created detailed digital(6) of the caves'paintings and sculptures.These digital versions allow people around the world to (7) the art without causing physical damage to the originals.The project has been particularly (8) for scholars who previously had limited access to the remote site. The technology (9) more than just preservation.Through virtual reality,visitors can now experience the caves as they might have appeared centuries ago,with colors restored to their(10) brightness.Animations bring ancient scenes to life,showing how the art was(11) and used in religious ceremonies. Despite these advances,some critics argue that digital(12) can never truly capture the experience of standing in the actual caves.The(13) of the space,the texture of the walls,the play of lightthese elements are(14) to translate into pixels.Yet supporters contend that digital preservation is not about replacement but about(15) -ensuring that future generations can study and appreciate these masterpieces even if the physical originals deteriorate. 1.A.restricted B.transformed C.maintained D.prevented 2.A.significant B.shallow C.trivial D.limiting 3.A.contain B.replace C.harm D.ignore 4.A.development B.improvement C.destruction D.growth 5.A.harmful B.rewarding C.trivial D.negative 6.A.arguments B.copies C.additions D.authorities 7.A.concentrate B.explore C.argue D.harm 8.A.limiting B.shallow C.valuable D.harmful 9.A.offers B.needs C.refuses D.argues 10.A.original B.concerned C.trivial D.shallow 11.A.replaced B.created C.harmed D.ignored 12.A.additions B.replacements C.authorities D.arguments 13.A.atmosphere B.replacement C.addition D.argument 14.A.easy B.difficult C.rewarding D.trivial 15.A.destruction B.preservation C.harm D.limitation 三、阅读短文回答问题 Read the following passage and answer the questions in complete sentences The integration of information technology into education has sparked heated debate among educators, parents,and policymakers.Proponents argue that digital tools enhance learning by providing personalized instruction,instant feedback,and access to vast resources.Critics,however.warn that excessive screen time may impair students'concentration,reduce face-to-face interaction,and widen the digital divide between affluent and disadvantaged communities. A recent study conducted by the University of Melboume examined the effects of tablet-based learning on primary school students over two years.The findings revealed a nuanced picture:while students using educational apps showed improved performance in mathematics and problem-solving tasks,their reading comprehension scores remained unchanged.More conceming,researchers observed a 15%decrease in students'ability to maintain focus during extended reading sessions without digital aids. The study also highlighted the importance of teacher guidance.In classrooms where educators actively integrated technology into lessons-rather than using it as a passive replacement for traditional instruction -students demonstrated better critical thinking skills.Dr.Emma Watson,the lead researcher,emphasized that "technology is a tool,not a teacher.Its effectiveness depends entirely on how it is implemented." School districts across the globe are now grappling with how to balance digital and traditional leaming methods.Some have adopted "blended learning"models that combine online resources with in-person instruction.Others have implemented"digital detox"programs to ensure students develop essential offline skills.The challenge lies not in choosing between technology and tradition but in finding the optimal mix that prepares students for a digitally driven world without sacrificing the foundational skills that only human interaction can cultivate 1.What are the main concerns critics have about IT in education?(List at least two) 2.What did the University of Melboume study find about students'reading comprehension? 3.According to Dr.Emma Watson,what determines the effectiveness of technology in education? 4.What is "blended leaming"as mentioned in the passage? 5.What does the author suggest is the real challenge regarding technology in education? 四、短文填空 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。 Social media has become an (1) part of modern life,but its effects on mental health are (2) about.Psychologists have found that constant(3) to carefully curated images of others'lives can lead to feelings ofinadequacy and anxiety.The pressure to (4) a perfect online image often results in what researchers call "social comparison fatigue." However,not all social media use is (5) When used (6) these platforms can foster genuine connection.Online communities provide support for people with (7) interests or experiences,from rare diseases to niche hobbies.The key is(8) on meaningful interaction rather than passive scrolling. Experts recommend (9) "digital boundaries"-specific times or places where phone use is (10) This practice helps users (11) real-world relationships that are more (12) than online ones.(13) to screen time,they suggest engaging in activities that require full concentration,such as reading,exercise,or face-to-face conversations. (14) young people are encouraged to critically evaluate the content they consume online. Understanding that social media presents a(15) version of reality can help reduce its negative psychological impact. 1. 2. 3. 4. 5. 6 8. 9. 10. 11. 12. 13. 14. 15. 五、写作 Directions:Write an essay of about 150-200 words on the following topic. Topic:Social media has become an essential part of teenagers'lives.Some people think it benefits young people by helping them stay connected and express themselves,while others believe it causes more harm than good.Discuss both views and give your own opinion. Your essay should: State both sides of the argument clearly Provide specific reasons and examples Express your own opinion with supporting evidence Social Media and Teenagers:A Double-Edged Sword Social media has become deeply embedded in teenagers'daily routines,sparking debate about its overall impact.On one hand,proponents argue that these platforms help young people maintain fiiendships across distances and express their creativity through photos,videos,and personal blogs.For many teenagers,especially those with niche interests or who feel isolated in their immediate environment,online communities provide crucial support and a sense of belonging. On the other hand,critics highlight significant drawbacks.Excessive social media use has been linked to increased anxiety,depression,and poor sleep quality among adolescents.The constant comparison with curated online images can damage self-esteem,while cyberbullying remains a serious concemn.
