Ⅰ.阅读理解 [话题　网络世界与现实世界之间的差异] You leave an hour of online surfing with the sense that the world is falling apart. In the real world, however, a neighbor you disagree with politically helps you start your car. The 　dissonance 　 is no accident. It is how today's Internet works. To better understand this gap, researchers surveyed 1,090 adults and found that people dramatically overestimate how common harmful behavior on the Internet is. On Reddit, participants thought harmful commenters were 13 times more common, estimating 43% of users post harmful content, while the actual figure is just 3%. Most offensive posts come from a small group of highly active users, whose outsized posts shape public beliefs, creating the “majority illusion” that makes this minority seem like the norm, drowning out the silent majority. Our brains are wired to notice threats and moral breaks — negative content sticks in our minds. Additionally, social media algorithms (算法) prioritize content that causes strong reactions to keep users engaged, with falsehoods spreading faster than truth. Bot networks (僵尸网络) add to the noise: it has been reported that bad bots make up roughly a third of global web traffic, misleading what trends and who appears popular. Measuring online harmful content is tricky, as automated tools often miss unobvious aggressive remarks. But what matters more is not “how harmful is the Internet，” but what ordinary users perceive as normal. Social psychologists call this dynamic “pluralistic ignorance”： people privately reject harmful norms but go along with them publicly. This misconception formed online creates a dangerous gap, fueling public distrust, preventing public participation, and lowering moral standards — if we think “everyone is awful，” we're less likely to be kind. While there is no silver bullet, practical steps — rooted in policy and personal awareness — can narrow the gap. The key lies in recognizing online engagement doesn't equal approval: skip “most engaging” feeds and ground our views in actual world connections. Imagine a public square where the loudest few don't seize the microphone — disagreement remains, but the air resounds with daily life: neighbors helping start cars, strangers holding doors. Online, we can make that reality visible again. 1．What does the underlined word “dissonance” in Paragraph 1 probably mean? A．Disorder.　　　　　 B．Prejudice. C．Contrast. D．Debate. 2．What does the “majority illusion” refer to in the text? A．A false impression. B．A harmful behavior. C．An overestimated post. D．A minority of commenters. 3．What is Paragraph 3 mainly about? A．Why global web traffic misleads people. B．Why the minority feels like the majority. C．How we identify online harmful content. D．What harm online misconception causes. 4．What is the author's suggestion in the last paragraph? A．Acting like the loudest few. B．Improving moral standards. C．Avoiding online engagement. D．Valuing real­life interactions. [语篇解读]　本文是一篇说明文。文章主要介绍了网络世界与现实世界之间的差异，指出人们往往高估网络上的有害行为，并分析了造成这种认知偏差的原因及其影响，最后提出了缩小这一差距的建议。 1．C　[词句猜测题。根据第一段中“You leave an hour of online surfing with the sense that the world is falling apart. In the real world, however, a neighbor you disagree with politically helps you start your car. The 　dissonance 　 is no accident. (你上网一小时后，感觉世界要崩溃了。然而，在现实世界中，一个与你政治观点不同的邻居却帮你发动了汽车。这种　dissonance 　并非偶然)”可知，前一句描述了网络世界带来的负面感受，后一句则通过现实中的例子展示了与网络世界截然不同的积极体验，两者形成对比。由此可推测，划线词dissonance指的是这种“对比”，与C项“Contrast”意思相近。故选C项。] 2．A　[词句猜测题。根据第二段中“Most offensive posts come from a small group of highly active users, whose outsized posts shape public beliefs, creating the ‘majority illusion’ that makes this minority seem like the norm, drowning out the silent majority.”可知，少数高度活跃的用户通过发布大量帖子，使公众误以为他们的行为是大多数人的行为，从而形成了一种“错误的印象”。由此可推测，“majority illusion”指的是“错误的印象”。故选A项。] 3．B　[主旨大意题。根据第三段“Our brains are wired to notice threats and moral breaks — negative content sticks in...... what trends and who appears popular.”可知，本段主要分析了为什么少数高度活跃的用户会感觉像多数，即解释了“多数错觉”产生的原因。故选B项。] 4．D　[推理判断题。根据最后一段中“The key lies in recognizing online engagement doesn't equal approval: skip ‘most engaging’ feeds and ground ......start cars, strangers holding doors. Online, we can make that reality visible again.(关键在于认识到网络参与并不等于认可：跳过‘最吸引人’的动态，将我们的观点建立在现实世界的联系上。想象一个广场，在那里，声音最大的几个人不会抢走麦克风——分歧依然存在，但空气中回荡着日常生活：邻居帮忙发动汽车，陌生人为你开门。在网上，我们可以让这种现实再次可见。)”可知，作者建议人们应该重视现实生活中的互动，而不是仅仅关注网络上的动态。故选D项。] Ⅱ.七选五 [话题　欧洲科技生态] The UK, Finland, Germany, and Sweden are consistently the top performers in European tech ecosystems.These countries also have the largest economies in Europe. 　__1__ 　 Well, let's find out now. 2__ 　 Even more amazing?

Finland is second in digital life overall, and first in cashless payment.This is because the Internet plays a vital role in Finland's digital life.High­speed Internet access and freedom of speech make the Finnish ecosystem more sustainable, with good Internet access and mobile coverage in remote areas. 　__3__ 　 Since the beginning, Germany's industry has supported scientific research.German society and economy take pride in their research­development efforts. 　__4__ 　 Mercedes, BMW, and Volkswagen are some examples. Sweden is a leader in technological innovation, with remarkable achievements in web development and mobile apps.For years, Ericsson and other large tech companies dominated the market. 　__5__ 　 Other Swedish companies like Spotify, Torrent, and Skype are now leading the charge.

B．The tide has turned today. C．Most residents there can switch on easily. D．We want to see how Europe's tech countries compare. E．Not all the countries experienced the smooth development. F．This is supported by evidence from global automotive brands. G．The British Empire was once the most developed country in the world. [语篇解读]　这是一篇说明文。文章比较了欧洲科技生态系统中表现最好的国家——英国、芬兰、德国和瑞典。 1．D　[根据空后的“Well, let's find out now.(好吧，现在让我们来看看。)”以及第二段中“The UK government and its businesses have been spending billions of dollars on research and development to drive innovation in Biotech.(英国政府及其企业已经在研发上投入了数十亿美元，以推动生物技术的创新。)”、第三段中“Finland is second in digital life overall, and first in cashless payment.(芬兰的数字生活总体排名第二，无现金支付排名第一。)”、第四段中“Since the beginning, Germany's industry has supported scientific research.(从一开始，德国的工业就支持科学研究。)”和第五段中“Sweden is a leader in technological innovation, with remarkable achievements in web development and mobile apps.(瑞典是技术创新的领导者，在网页开发和移动应用方面取得了卓越的成就。)”可知，下面的文章是对这四个国家的技术进行了比较。D项“We want to see how Europe's tech countries compare.(我们想看看欧洲的科技国家如何比较。)”可以引出后文，且D项中“Europe's tech countries”指代的就是上文中的“The UK, Finland, Germany, and Sweden ”，与后文段落中比较的国家也一致。] 2．G　[根据后文 “The UK government and its businesses have been spending billions of dollars on research and development to drive innovation in Biotech.(英国政府及其企业已经在研发上投入了数十亿美元，以推动生物技术的创新。)”可知本段讲的是英国的科技。G项“The British Empire was once the most developed country in the world.(大英帝国曾经是世界上最发达的国家。)”可作本段主题句。且“ Even more amazing? (更神奇的是？ )”是对前一句的肯定和对后文“This country is home to many basic scientific principles.(这个国家有许多基本的科学原理。)”的铺垫，“This country”指的就是G项中“The British Empire”。] 3．C　[前文“High­speed Internet access and freedom of speech make the Finnish ecosystem more sustainable, with good Internet access and mobile coverage in remote areas.(高速互联网接入和言论自由使芬兰的生态系统更具可持续性，在偏远地区有良好的互联网接入和移动覆盖。)”说明了网络很好地覆盖了芬兰的偏远地区。C项“Most residents there can switch on easily.(那里的大多数居民都能轻松接通(网络)。)”与前文意义一致，且C项中“there”指上文中的“in remote areas”。] 4．F　[后文“Mercedes, BMW, and Volkswagen are some examples.(奔驰、宝马和大众就是一些例子。)”属于汽车品牌。F项“This is supported by evidence from global automotive brands.(这得到了全球汽车品牌的支持。)”能够自然引出后文。] 5．B　[前文“ For years, Ericsson and other large tech companies dominated the market.(多年来，爱立信和其他大型科技公司主导着市场。)”与后文“Other Swedish companies like Spotify, Torrent, and Skype are now leading the charge.(其他瑞典公司，如Spotify、Torrent和Skype，现在正在引领这一潮流。)”形成了转折，即主导的科技公司发生了变化。B项“The tide has turned today.(今天形势发生了变化。)”作为过渡句，符合语境。] Ⅲ.语法填空 [话题　AI农业应用] In Chengdu, robots 1.　____________ 　 (equip) with HD cameras regularly inspect smart greenhouses day and night. 2.　____________ 　 the DeepSeek model, the robots' developers trained the robots through numerous images to improve their pest identification 3.　____________ 　 (accurate)．Developer Wu Yuanqing explains these robots aim to improve farming efficiency 4.　____________ 　 (significant) by cutting labor costs by half.So far, 69 sets of 5G­powered Internet of Things sensors have been installed in Maoming's 20 towns, 5.　________ 　 (mark) a regional shift toward tech­driven agriculture with enhanced risk prediction capabilities.
