A little effort every day, you’ll make a big difference. Unit 1 Science Fiction Science fiction is a genre that has captivated readers for centuries. It allows us to explore the unknown and imagine what the future might hold. One of the most fascinating aspects of science fiction is its ability to 1 real scientific concepts with imaginative storytelling. Many classic science fiction works have 2 predictions that later came true. For example, Jules Verne wrote about space travel long before humans actually 3 the moon. Similarly, works by Isaac Asimov explored robotics and artificial intelligence decades before these technologies became part of our 4 lives. What makes science fiction particularly valuable is its role in 5 scientific progress. By presenting possible future scenarios, it encourages scientists and engineers to turn fiction into reality. It also serves as a warning, showing us the potential 6 of unchecked technological development. Modern science fiction continues to 7 important questions about humanity’s relationship with technology. Will artificial intelligence eventually 8 human workers? Can we colonize other planets before Earth becomes 9 ? These questions may seem distant, but they are becoming increasingly relevant. Reading science fiction also develops our critical thinking skills. It challenges us to consider the ethical 10 of scientific discoveries and to think about what it truly means to be human in an age of rapid technological 11 . The best science fiction doesn’t just entertain; it makes us reflect on our present and 12 our choices for the future. For young readers, science fiction opens doors to scientific 13 . Many scientists credit their career choices to early 14 with science fiction books and films. The genre proves that imagination and scientific inquiry are not opposites but rather 15 partners in the pursuit of knowledge. 1. A. replace B. combine C. compare D. separate 2.

A. natural B. opposite C. similar D. necessary Unit 2 Iconic Attractions When we think of iconic attractions around the world, certain images immediately come to mind. These landmarks are more than just beautiful sights; they represent the history, culture, and 1 of the places where they stand. The Eiffel Tower in Paris, for instance, was initially 2 by many locals when it was first built. Critics called it an eyesore and predicted it would soon be 3 . However, over time, it became the most recognizable symbol of France and one of the most 4 monuments in the world. What transforms a building or natural wonder into an iconic attraction? Often, it is the stories and emotions 5 with the site. The Great Wall of China represents centuries of human effort and 6 . The Grand Canyon in America showcases the 7 power of nature over millions of years. Iconic attractions also play a significant economic role. They draw millions of tourists each year, creating jobs and 8 local economies. However, this popularity can create challenges. Overcrowding may 9 the very beauty that attracts visitors in the first place. Some famous sites have had to 10 visitor numbers to protect their historical structures. In recent years, the concept of iconic attractions has 11 . Social media has turned lesser-known locations into overnight sensations. A single photograph shared online can make a hidden beach or mountain village 12 famous worldwide. For travelers, visiting iconic attractions offers more than photo opportunities. It provides a chance to connect with human 13 across time and space. Standing before ancient ruins or modern masterpieces, we gain a deeper 14 of both the past and our shared humanity. Ultimately, iconic attractions remind us that certain places have the power to 15 us, to make us feel part of something larger than ourselves. 1. A. identity B. weather C. distance D. silence 2.

A. forget B. frighten C. inspire D. disappoint Unit 3 Sea Exploration The ocean covers more than seventy percent of our planet’s surface, yet it remains one of the least 1 areas on Earth. For centuries, the deep sea has captured human imagination, representing both mystery and 2 . Early sea exploration was driven by practical needs. Ancient civilizations explored coastlines for trade routes and fishing grounds. The Polynesians, for example, 3 vast areas of the Pacific Ocean using only stars, waves, and birds as their 4 . Their remarkable navigation skills allowed them to settle islands separated by thousands of kilometers. Modern ocean exploration began in earnest during the twentieth century. In 1960, two explorers descended to the deepest point of the ocean, the Mariana Trench, proving that humans could 5 extreme underwater pressure. Since then, technology has 6 dramatically. Submersibles now carry scientists to depths that were once thought 7 . What drives us to explore the ocean? Partly, it is scientific curiosity. The deep ocean contains 8 life forms that have adapted to conditions of total darkness and crushing pressure. Some of these organisms may hold 9 to medical breakthroughs, producing chemicals that could treat human diseases. Beyond science, the ocean offers practical resources. Underwater minerals, energy sources, and even fresh water reserves are increasingly 10 as land-based resources become scarce. However, extracting these resources raises serious environmental 11 . We must balance human needs with the protection of fragile marine ecosystems. Perhaps the most compelling reason for ocean exploration is the search for understanding. The ocean regulates our climate, produces the oxygen we breathe, and 12 countless species. By studying it, we learn more about our planet’s past and its 13 future. The challenges of ocean exploration are significant. High pressure, darkness, and cold make the deep sea a hostile 14 . Yet each dive reveals something new, reminding us that our own planet still holds secrets waiting to be 15 . 1. A. explored B. developed C. protected D. polluted 2.

A. threatens B. replaces C. reduces D. supports 13. A. uncertain B. immediate C. distant D. peaceful 14. A. garden B. friend C. environment D. museum 15. A. forgotten B. discovered C. created D. imagined Unit 4 Sharing In a world that often emphasizes personal achievement and material success, the simple act of sharing can seem old-fashioned. Yet sharing remains one of the most powerful forces for building 1 and improving lives. Sharing takes many forms. We share food with hungry neighbors, share knowledge with eager students, and share our time with those who feel 2 . Each act of sharing, no matter how small, creates connections between people and 3 the giver as much as the receiver. The benefits of sharing extend beyond individual relationships. Communities that embrace sharing often develop stronger social 4 . When people share tools, vehicles, or even living spaces, they reduce waste and build trust. The “sharing economy,” which has 5 in recent years, applies this principle to modern business. Platforms that allow people to share rides, apartments, and skills have changed how we think about 6 . However, true sharing involves more than economic transactions. It requires empathy—the ability to understand and share the feelings of others. When we genuinely care about another person’s well-being, sharing becomes natural rather than 7 . A child who shares toys because she sees her friend is upset demonstrates this emotional connection. Sharing also plays a crucial role in addressing global challenges. International 8 on scientific research has led to breakthroughs in medicine and technology. Countries that share resources during natural disasters demonstrate humanity’s capacity for 9 . Without such cooperation, many problems would remain 10 . Some argue that excessive sharing weakens individual responsibility. They worry that people may become 11 on others rather than developing self-reliance. This concern has some validity, but it overlooks an important truth: sharing and personal responsibility are not 12 . In fact, people who share often develop greater confidence and competence. Educators increasingly recognize the importance of teaching sharing to young people. Schools organize activities that require teamwork and 13 . These experiences help students understand that success often depends on collective effort rather than 14 competition. In the end, sharing reflects our deepest human values. It acknowledges that we are social beings who 15 one another. By sharing what we have—whether material goods, knowledge, or emotional support—we create a world that is richer for everyone. 1.

A. avoid B. need C. ignore D. replace Unit 5 Launching Your Career Choosing a career path is one of the most significant decisions young people face. It shapes not only their financial future but also their sense of purpose and personal 1 . The journey from student to professional requires careful thought and active preparation. The first step in launching a career is self-assessment. Understanding your strengths, weaknesses, and 2 helps identify suitable fields. Some people excel at analytical thinking and may thrive in research or finance. Others with strong communication skills might find 3 in teaching, sales, or public relations. Ignoring your natural abilities often leads to frustration and career 4 . Once you identify potential fields, gaining practical experience becomes essential. Internships, part-time jobs, and volunteer work provide valuable insights into professional 5 . They also help build networks of contacts who may offer guidance or job 6 in the future. Many successful professionals credit their early experiences with shaping their career 7 . Education remains a foundation for most careers, but learning doesn’t stop at graduation. Industries evolve rapidly due to technological 8 and changing market demands. Professionals who commit to lifelong learning—whether through formal courses, online resources, or workplace training—maintain their 9 in the job market. The modern workplace also values soft skills. Employers seek candidates who can work in teams, solve problems creatively, and 10 to changing circumstances. Technical expertise alone is rarely sufficient; the ability to collaborate and communicate effectively often 11 the difference between average and outstanding performance. Launching a career inevitably involves setbacks. Rejected applications, failed interviews, and unexpected changes are common experiences. Rather than viewing these as failures, successful career builders treat them as learning 12 . Each challenge offers an opportunity to refine goals and develop resilience. For those uncertain about their direction, career counseling can provide clarity. Professional advisors use assessments and discussions to help individuals explore options they might not have 13 . Sometimes, the perfect career is one you never imagined. Ultimately, a fulfilling career aligns personal values with professional activities. When your work reflects what you genuinely care about, it becomes more than a means to earn money. It becomes a source of 14 and personal growth. The effort invested in planning and preparing for your career will 15 rewards throughout your working life. 1. A. temperature B. appearance C. weight D. satisfaction 2.

B. combine 根据上下文，科幻小说最迷人的地方在于它能够将真实的科学概念与富有想象力的叙事结合在一起。 "combine A with B” 为固定搭配，意为“将A与B结合”。replace（替换）、compare（比较）、separate（分离）均不符合语境。科幻小说的核心特征正是融合科学与想象，而非替代、比较或分离二者。 2. A. made “make predictions” 为固定搭配，意为“做出预测”。许多经典科幻作品做出了后来成真的预测。refuse（拒绝）、ignore（忽视）、forget（忘记）均与后文 “came true”（成真）的积极语义不符。 3. D. reached 人类到达/登上月球，应使用动词 reach。discover（发现）指发现原本存在但未知的事物；observe（观察）强调观看而非抵达；invent（发明）指创造新事物。月球一直存在，人类是“抵达”而非“发现”或“发明”它。 4. A. daily 机器人和人工智能成为“日常生活”的一部分。 “daily lives” 为固定搭配，意为“日常生活”。ancient（古代的）、secret（秘密的）、political（政治的）均不符合语境——这些技术已成为大众日常体验。 5. C. inspiring 根据后文 “turn fiction into reality”（将虚构变为现实）可知，科幻小说在激励/启发科学进步。preventing（阻止）、delaying（延迟）、finishing（完成）均与后文积极导向相反。 6. B. dangers 前文提到 “serves as a warning”（起到警示作用），警示的应是技术发展的潜在危险。advantages（优势）与warning矛盾；methods（方法）、standards（标准）与 “unchecked”（不受约束的）搭配不当。 7. D. raise “raise questions” 为固定搭配，意为“提出问题”。现代科幻小说继续提出关于人类与技术关系的重要问题。avoid（避免）、copy（复制）、repeat（重复）均不符合科幻小说积极探索的特质。 8. A. replace 人工智能是否会取代人类工作者，这是当前热门议题。follow（跟随）、praise（赞扬）、recognize（认出/认可）均不符合对AI替代人类工作的普遍担忧。 9. C. uninhabitable 在地球变得不适宜居住之前，我们能否殖民其他星球？这是科幻小说的经典命题。beautiful（美丽的）、crowded（拥挤的）、peaceful（和平的）虽可描述地球，但 “before...becomes...”暗示负面变化，uninhabitable（无法居住的）最符合殖民其他星球的紧迫性前提。 10. B. consequences 科幻小说促使我们思考科学发现的伦理后果。traditions（传统）、celebrations（庆祝）、competitions（竞争）均与 “ethical”（伦理的）搭配不当，伦理关注的是行为后果而非传统或庆祝。 11. A. advance “technological advance” 为固定搭配，意为“技术进步”。silence（沉默）、accident（事故）、conflict（冲突）均不能与 “rapid technological”形成合理搭配。 12. D. question 最好的科幻小说不仅娱乐大众，还促使我们反思当下并质疑未来的选择。regret（后悔）、repeat（重复）、forget（忘记）均不符合批判性思维的内涵——question（质疑）体现了独立思考。 13. B. curiosity 科幻小说为青少年打开了科学好奇心的大门。 “scientific curiosity” 为常见搭配，指对科学的好奇与探索欲。mystery（神秘）、anxiety（焦虑）、difficulty（困难）均不符合 “opens doors to”（开启……之门）的积极语义。 14. C. exposure 许多科学家将职业选择归功于早期接触科幻书籍和电影。 “exposure to” 为固定搭配，意为“接触/暴露于”。agreement（同意）、disagreement（不同意）、opposition（反对）均无法表达“接触作品”的含义。 15. D. necessary 想象力与科学探究不是对立面，而是追求知识过程中必要的伙伴。natural（自然的）虽可搭配，但necessary更强调二者缺一不可的互补关系；opposite（对立的）与前文 “not opposites”矛盾；similar（相似的）忽略了二者本质差异。 Unit 2 答案： 1---5 ACBDA 6---10 DBACD 11---15 CABBC 文本导语 本文是一篇说明文，围绕“标志性景点（iconic attractions）”这一主题展开。文章从埃菲尔铁塔的争议性起源切入，探讨了地标建筑如何从最初的不被认可转变为文化符号；继而分析了景点成为“标志性”的内在原因（历史故事与情感联结）和外在影响（经济价值与环境压力）；最后结合社交媒体时代的新现象，阐述了这些景点对人类精神层面的深层意义。全文逻辑清晰，由表及里，从具体案例到抽象思考，层层递进。 答案详细解析 1. A. identity 空格处与history、culture构成并列关系，共同说明地标所代表的深层内涵。identity（身份认同）符合语境——地标不仅是美景，更代表一个地方的历史、文化和身份认同。weather（天气）、distance（距离）、silence（沉默）均与“代表某地内涵”无关。 2. C. opposed 根据下文 “Critics called it an eyesore”（批评家称其为眼中钉）可知，埃菲尔铁塔最初遭到反对。praised（赞扬）与文意相反；ignored（忽视）程度不足，因为批评家 actively 发表了负面评价；copied（复制）不合语境。 3. B. removed 批评家不仅称其为眼中钉，还预测它很快会被拆除。removed（移除、拆除）与eyesore的负面评价一脉相承。repaired（修复）、expanded（扩建）、decorated（装饰）均为正面或中性动作，与批评态度矛盾。 4. D. visited 由 “most recognizable symbol of France”（法国最 recognizable 的标志）可推知，它成为世界上参观人数最多的纪念碑之一。visited（被参观的）符合旅游景点的属性。private（私人的）、avoided（被回避的）、hidden（隐藏的）均与“标志性景点”的身份相悖。 5. A. connected 固定搭配 “connected with”（与……相关联）。句意：往往是与这个地方相关联的故事和情感，使其成为标志性景点。confused with（与……混淆）、charged with（被指控）、covered with（被覆盖）均不符合语境。 6. D. determination 长城代表的是数百年的人类努力和决心。determination（决心、毅力）准确概括了修建长城所需的巨大意志品质。weakness（软弱）、sadness（悲伤）、laziness（懒惰）均为负面词汇，与对长城的正面赞颂不符。 7. B. creative 大峡谷展现的是大自然数百万年来的创造性力量。creative（创造性的）强调自然造物的鬼斧神工，与“塑造壮丽景观”呼应。gentle（温和的）与峡谷的雄伟气势不符；destructive（破坏性的）为负面词，与作者赞叹自然的语气不符；positive（积极的）过于笼统。 8. A. supporting 标志性景点每年吸引数百万游客，创造就业并支撑地方经济。supporting（支持、支撑）准确描述景点对经济的正面作用。damaging（破坏）与文意相反；controlling（控制）、testing（测试）不搭配economies。 9. C. damage 然而，这种 popularity 也会带来挑战。过度拥挤可能会破坏最初吸引游客的美景。damage（损害）呼应上文的challenges。protect（保护）、improve（改善）与“挑战”的负面语境矛盾；discover（发现）不合逻辑。 10. D. limit 一些著名景点不得不限制游客数量以保护其历史建筑。limit（限制）是解决 overcrowding 的合理措施。increase（增加）会加剧问题；ignore（忽视）、count（计数）无法起到保护作用。 11. C. expanded 近年来，标志性景点的概念已经扩展。下文提到社交媒体将不知名地点变成一夜爆红的目的地，说明概念范围扩大了。disappeared（消失）、failed（失败）与下文例证矛盾；simplified（简化）未体现。 12. A. suddenly 网上分享的一张照片可以使隐秘的海滩或山村突然闻名世界。overnight sensations（一夜成名）提示此处强调速度之快，suddenly（突然地）最贴切。slowly（缓慢地）与 “overnight”矛盾；rarely（罕见地）、secretly（秘密地）不合语境。 13. B. achievements 对旅行者而言，参观标志性景点不仅是拍照机会，更是与不同时空的人类成就建立联结的机会。achievements（成就）与ancient ruins、modern masterpieces呼应，体现人类文明成果。arguments（争论）、accidents（事故）、agreements（协议）均过于狭窄或负面。 14. B. understanding 站在古代遗迹或现代杰作前，我们对过去和共同的人性获得更深层的理解。understanding（理解）与 “connect with”和 “deeper”搭配自然。description（描述）、imagination（想象）、instruction（指导）均不如understanding准确。 15. C. inspire 标志性景点提醒我们，某些地方有能力激励我们，让我们感到自己是比自身更宏大的事物的一部分。inspire（激励、启发）与 “feel part of something larger”的升华感完美契合。forget（遗忘）、frighten（惊吓）、disappoint（失望）均为负面词，与全文积极基调不符。 Unit 3 答案： 1-5 ABCDA 6-10 BCDAC 11-15 BDACB 文本导语 本文是一篇关于海洋探索的说明文，采用“总—分—总”结构。文章首先指出海洋覆盖地球表面70%以上，却仍是人类了解最少的领域之一；接着按时间顺序回顾了从古代到现代的海洋探索历程；随后从科学好奇心、实际资源需求和寻求认知理解三个维度阐述了人类探索海洋的动机；最后指出深海环境的恶劣与挑战，同时强调地球仍有许多秘密等待人类去发现。 答案详细解析 1. A. explored 根据上下文，海洋覆盖地球表面70%以上，却仍是地球上探索最少的区域之一。后文围绕“探索”展开，从古代航海到现代深潜，均呼应此主题。developed（开发的）、protected（保护的）、polluted（污染的）均与文章主旨不符。 2. B. danger 由 “mystery and...”可知，此处需与mystery（神秘）并列且感情色彩相近的词。深海既代表神秘，也代表危险，这是人类对深海的经典双重认知。safety（安全）和comfort（舒适）与语境矛盾；silence（寂静）虽可描述深海，但与mystery不构成并列关系。 3. C. crossed 波利尼西亚人是著名的航海民族，他们穿越了太平洋的广阔区域。avoided（避开）与探索精神相悖；discovered（发现）后通常直接接地点，不与areas搭配；destroyed（摧毁）不符合语境。 4. D. guides 他们仅利用星星、海浪和鸟类作为向导/指引进行导航。enemies（敌人）、gifts（礼物）、passengers（乘客）均与导航功能无关。 5. A. survive 1960年，两位探险家下潜至马里亚纳海沟最深处，证明人类能够承受/存活于极端水下压力。measure（测量）虽可说通，但此处强调的是人类在极端环境下的生存能力；increase（增加）和escape（逃离）与语境不符。 6. B. advanced 从那以后，技术进步显著。disappeared（消失）、repeated（重复）、failed（失败）均与后文“潜水器能携带科学家到达……深度”的积极描述矛盾。 7. C. impossible 潜水器现在能到达曾被认为不可能到达的深度。reachable（可达到的）与 “once thought”（曾被认为）矛盾；suitable（合适的）、available（可获得的）不符合语境。 8. D. unusual 深海包含不寻常的生命形式，它们适应了完全黑暗和巨大压力的环境。familiar（熟悉的）、similar（相似的）、ordinary（普通的）均与“适应极端环境”的描述矛盾。 9. A. keys 固定搭配 “hold keys to...”表示“掌握……的关键”。这些生物可能掌握着医学突破的关键，产生能治疗人类疾病的化学物质。barriers（障碍）与积极意义矛盾；introductions（介绍）、negotiations（谈判、磋商）均不符合语境。 10. C. valued 随着陆地资源日益稀缺，海底矿产、能源甚至淡水储备越来越受重视。ignored（被忽视的）、wasted（被浪费的）与资源稀缺的语境矛盾；hidden（隐藏的）不符合 “ increasingly”（日益）的递进逻辑。 11. B. concerns 然而，开采这些资源引发了严重的环境担忧。celebrations（庆祝）、preparations（准备）、advantages（优势）均与 “serious environmental”（严重的环境）及转折语气不符。 12. D. supports 海洋调节气候、产生氧气并维系/支撑无数物种。threatens（威胁）、replaces（替代）、reduces（减少）均与海洋的生态功能描述矛盾。 13. A. uncertain 通过研究海洋，我们更多了解地球的过去及其不确定的未来。immediate（立即的）、distant（遥远的）、peaceful（和平的）均不如uncertain准确——面对气候变化等挑战，未来具有不确定性，这正是研究海洋的意义所在。 14. C. environment 高压、黑暗和寒冷使深海成为一个恶劣的环境。friend（朋友）、garden（花园）、museum（博物馆）的比喻均与 “hostile”（敌对的/恶劣的）不搭配。 15. B. discovered 然而每次下潜都有新发现，提醒我们地球仍有许多秘密等待被发现。forgotten（被遗忘）、created（被创造）、imagined（被想象）均与 “secrets”（秘密）和前文 “reveals something new”（揭示新事物）的逻辑不符。 Unit 4 答案： 1-5 ADBCA 6-10 DACCB 11-15 ABDCB 文本导语 本文是一篇议论文，主题为“分享的力量”。文章从个人层面延伸到社区、经济乃至全球合作，层层递进地论证了分享在构建人际关系、促进社会发展和应对全球挑战中的重要作用，同时回应了“分享会削弱个人责任感”的质疑，最终强调分享是人类深层价值的体现。 答案详细解析 1. A. communities 文章开篇点题，强调分享对“构建社区（communities）”和改善生活的作用。后文多次出现 “communities”（第4空所在句），形成词汇复现。B项 “建筑物”、C项“机器”、D项“边境”均与“分享”的主题无关。 2. D. lonely 此处描述分享时间的对象——那些感到“孤独（lonely）”的人。与“分享时间”形成逻辑匹配的是情感上需要陪伴的人。A“兴奋的”、B“惊讶的”、C“生气的”均不如“孤独的”贴切。 3. B. benefits 句意为“每一次分享行为，无论多小，都能在人与人之间建立联系，并使给予者和接受者同样受益”。B项“使受益”符合语境。A“伤害”与文意相反；C“控制”、D“测试”不合逻辑。 4. C. networks “social networks”指“社会网络/关系网”，是固定搭配。分享型社区会发展出更强的社会关系网络。A“织物”、B“距离”、D“沉默”均不符合。 5. A. expanded 共享经济近年来扩张/蓬勃发展（expanded）。B“消失”、C“失败”、D“暂停”与事实相反。 6. D. ownership 共享平台改变了人们对“所有权（ownership）”的看法——从拥有转向使用。A“教育”、B“惩罚”、C“娱乐”与共享经济的核心概念无关。 7. A. forced 前文说“当我们真正关心他人福祉时，分享变得自然”，rather than 表示转折，故填“被迫的（forced）”，与 “natural”形成对比。B“计划的”、C“自然的”（与rather than矛盾）、D“偶然的”。 8. C. cooperation 国际“合作（cooperation）”带来医学和技术突破。A“竞争”、B“分离”、D“困惑”与“带来突破”的积极语境不符。 9. C. kindness 灾难中共享资源体现了人类的“善良/仁慈（kindness）”。A“盲目”、B“软弱”、D“悲伤”均为负面词汇，与语境不符。 10. B. unsolved “Without such cooperation”（没有这样的合作），许多问题将“无法解决（unsolved）”。A“已解决的”与without矛盾；C“重复的”、D“被创造的”不合逻辑。 11. A. dependent 反对者担心人们变得“依赖（dependent）”他人，而不是培养自立能力。 “become dependent on”为固定搭配。B“独立的”与文意相反；C“自信的”、D“沉默的”不合语境。 12. B. opposite 这种担忧忽视了一个事实：分享和个人责任并非“对立的（opposite）”。后文 “In fact”进一步说明二者可以共存。A“相似的”、C“平等的”、D“熟悉的”均不如“对立的”准确。 13. D. cooperation 学校组织需要团队合作和“合作（cooperation）”的活动，与 “teamwork”并列。A“竞争”与teamwork矛盾；B“重复”、C“孤立”不合语境。 14. C. individual 集体努力而非“个人（individual）”竞争。与 “collective effort”形成对比。A“全球的”、B“国家的”、D“地区的”均不与 “collective”构成反义关系。 15. B. need 我们是“需要（need）”彼此的社会性存在。这与文章主旨——分享与相互依存——完美契合。A“避免”、C“忽视”、D“取代”均与文意相反。 Unit 5 答案： 1-5 DABDA 6-10 ACBDB 11-15 ABDCC 文本导语 本文是一篇夹叙夹议的说明文，围绕“如何开启职业生涯”展开论述。文章从自我评估、实践经验、终身学习、软技能、挫折应对、职业咨询等多个维度，系统阐述了年轻人从学生向职场人过渡时应做的准备与应具备的心态。全文逻辑清晰，层层递进，最后落脚于“个人价值与职业活动相统一”这一核心观点，具有较强的现实指导意义和积极的价值导向。 答案详细解析 1. D. satisfaction 本句意为“职业选择不仅塑造他们的经济未来，还塑造他们的使命感与个人满足感”。 “sense of purpose and personal satisfaction”为常见搭配，表示“使命感与个人满足感”，两者并列，语义递进。A项temperature（温度）、B项appearance（外貌）、C项weight（体重）均与语境无关。 2. A. interests 本段主题为“自我评估（self-assessment）”，与strengths（优势）、weaknesses（劣势）并列的应为interests（兴趣），三者共同构成自我认知的核心要素。B项clothes（衣服）、C项houses（房子）、D项vehicles（车辆）均不属于自我评估范畴。 3. B. success 前文说“擅长分析思维的人可能在研究或金融领域蓬勃发展（thrive）”，本句以 “Others...”形成对比，指“具有较强沟通能力的人可能在教学、销售或公关领域取得成功”。 “find success in...”为固定表达，意为“在……方面取得成功”。A项failure（失败）与语境相反；C项trouble（麻烦）、D项doubt（怀疑）不合逻辑。 4. D. dissatisfaction 本句意为“忽视自身天赋常常导致挫败感和职业不满”。前文 “frustration（挫败感）”提示此处应填负面情绪词，且与career搭配。D项dissatisfaction（不满）与frustration语义一致，构成并列。A项progress（进步）、B项change（变化）、C项satisfaction（满意）均与语境矛盾。 5. A. environments 本句意为“实习、兼职和志愿工作让人深入了解职业环境”。professional environments指“职业环境/职场环境”，符合语境。B项dreams（梦想）、C项vacations（假期）、D项traditions（传统）均与“实习、兼职”等实践活动所提供的内容不符。 6. A. opportunities 本句意为“建立人脉关系网，这些人未来可能提供指导或工作机会”。job opportunities为固定搭配，意为“工作机会/就业机会”。B项difficulties（困难）、C项excuses（借口）、D项delays（延误）均与“人脉提供”的积极语义不符。 7. C. directions 本句意为“许多成功人士将他们的早期经历归功于塑造了他们的职业方向”。career directions指“职业方向”，符合“早期经历对职业发展的影响”这一语境。A项accidents（事故）、B项mistakes（错误）、D项excuses（借口）均带有负面色彩，与 “successful professionals”的积极语境不符。 8. A. advance 本句意为“由于技术进步和不断变化的市场需求，行业发展迅速”。technological advance为固定搭配，意为“技术进步”，是推动行业演变的正面因素。B项retreat（撤退）、C项silence（沉默）、D项accident（事故）均不符合“行业快速发展”的语境。 9. D. competitiveness 本句意为“致力于终身学习的专业人士保持在就业市场上的竞争力”。competitiveness（竞争力）是终身学习的直接结果，符合逻辑。A项weakness（弱点）、B项confusion（困惑）、C项loneliness（孤独）均为负面词汇，与 “commit to lifelong learning”的积极意义相悖。 10. B. adapt 本句意为“雇主寻找能够团队合作、创造性解决问题并能适应变化环境的候选人”。adapt to为固定搭配，意为“适应”，与changing circumstances（变化的环境）搭配恰当，且与前文work in teams、solve problems creatively构成并列的技能要求。A项refuse（拒绝）、C项object（反对）与语境相反；D项lead to（导致）为及物短语，语法不符。 11. A. makes 本句意为“协作和有效沟通的能力往往造就了平庸与杰出表现之间的差别”。make the difference为固定搭配，意为“起作用、有影响、造就差别”，是完形填空高频考点。B项avoids（避免）、C项repeats（重复）、D项forgets（忘记）均无法与the difference构成合理搭配。 12. B. opportunities 本句意为“成功的职业建设者将它们视为学习的机会”。前文 “Rather than viewing these as failures”（不将其视为失败）提示此处应填积极词汇，learning opportunities（学习机会）符合“把挫折转化为成长契机”的语境。A项tools（工具）、C项disasters（灾难）、D项celebrations（庆祝）均不恰当。 13. D. considered 本句意为“帮助他们探索那些可能从未考虑过的选项”。might not have considered为虚拟语气，表示“过去未曾考虑过”，符合“职业咨询帮助发现新方向”的语境。A项avoided（避免）、B项forgotten（忘记）、C项achieved（实现）均不符合“探索未知选项”的语义。 14. C. pride 本句意为“它成为自豪感和个人成长的源泉”。前文 “When your work reflects what you genuinely care about”（当工作反映你真正关心的事物时）提示此处应填积极情感词，pride（自豪）与personal growth（个人成长）并列，语义一致。A项boredom（无聊）、B项pain（痛苦）、D项shame（羞愧）均为负面情绪，与语境矛盾。 15. C. produce 本句意为“为职业规划所投入的努力将在整个工作生涯中产生回报”。produce rewards意为“产生回报/带来回报”，符合“付出与收获”的逻辑关系。A项reduce（减少）、B项waste（浪费）、D项ignore（忽视）均与“投入努力获得回报”的积极语义相悖。 5 / 6 学科网（北京）股份有限公司 $
