From shared bikes to second-hand goods trading, from e-commerce sharing platforms to public resource sharing, sharing culture is gradually changing people’s lifestyle and values. Many people used to believe that owning more things brings happiness. But in fact, true happiness often comes from sharing. Sharing means caring about others and taking responsibility for society. When we share our books, clothes or useful experience with others, we are not just giving away things. Instead, we build a warm connection with people around us. For students, sharing learning materials and study skills helps everyone make progress together. For citizens, sharing public resources can reduce waste, cut down expenses and improve the environment. I have deeply experienced the happiness of sharing. Last term, I joined a community sharing activity. I sorted out my spare books and daily supplies and gave them to people in need. I also shared my internship experiences and learning methods with junior students. At first, I worried that I would lose my own things. However, I gained more than I lost. I made new friends, learned to care about others and became more financially independent in mindset. Sharing does not mean loss, but double happiness. It teaches us to be generous, responsible and warm-hearted. As long as we are willing to share, we can bring warmth to others and gain spiritual happiness in return. Sharing is a kind of lifestyle, and also a precious quality of modern teenagers. 1. What changes people’s lifestyle and values nowadays? A. Job hunting experience B. Sharing culture C. Independent living D. Financial independence 2. What benefit can sharing public resources bring? A. It helps people own more things B. It reduces waste and improves the environment C. It makes people become rich quickly D. It helps students finish internship easily 3. What did the writer do in the community sharing activity? A. Sold second-hand goods on a platform B. Shared learning and internship experience C. Reduced traffic problems in the community D. Learned to live on his own 4. What did the writer gain from sharing? A. More material wealth B. A lot of spare time C. Warm friendship and spiritual happiness D. Higher grades in exams 5. What is the main idea of the passage? A. The development of sharing economy B.

How to become independent teenagers 【答案】1.B 2.B 3.B 4.C 5.C 【导语】本文是议论文，围绕单元主题 The Happiness of Sharing 展开，介绍共享文化的发展与价值，结合生活实例阐述分享带来的成长与快乐。全文覆盖sharing economy、cut down waste、improve the environment、take responsibility等单元核心短语，考查细节理解、细节判断、主旨概括能力。 1. 【答案】B 【考点】细节理解题（原文定位匹配） 【详细解析】精准定位文章第一段关键句：sharing culture is gradually changing people’s lifestyle and values。句意：共享文化正逐渐改变人们的生活方式和价值观。逐一排除干扰项：A（求职经历）、C（独立生活）、D（经济独立）均为单元其他话题短语，文中无任何对应信息，属于无中生有选项，因此选B。 2. 【答案】B 【考点】细节理解题（原文原句复现） 【详细解析】定位第二段核心句：sharing public resources can reduce waste, cut down expenses and improve the environment，完全对应B选项“减少浪费、改善环境”。干扰项分析：A（拥有更多物资）与原文“分享不是占有”主旨相悖；C（快速致富）文中未提及；D（帮助完成实习）属于话题混搭，无原文依据，直接排除。 3. 【答案】B 【考点】细节理解题（事件细节筛选） 【详细解析】定位第三段：I also shared my internship experiences and learning methods with junior students，明确作者在活动中分享了实习经历和学习方法，对应B选项。干扰项排除：A（售卖二手商品），原文是捐赠分享而非售卖；C（减少社区交通问题）、D（独立生活）均不是本次社区分享活动的内容，话题不符。 4. 【答案】C 【考点】细节判断题（情感收获提炼） 【详细解析】根据文章最后两段内容，作者通过分享交到新朋友、学会关心他人、收获精神层面的满足与快乐，对应C选项“温暖的友谊和精神快乐”。干扰项分析：A（更多物质财富）与原文“分享不求物质回报”相反；B（大量空闲时间）、D（更高考试分数）全文无提及，属于无效干扰项。 5. 【答案】C 【考点】主旨大意题（全文主旨概括） 【详细解析】主旨题需覆盖全文：文章开篇引出共享文化，中间结合个人经历讲述分享的行为与收获，结尾升华分享的价值与快乐，全文围绕“分享的价值与快乐”展开，对应C选项。其余选项均为局部细节：A仅对应首段现象、B仅对应环保细节、D仅对应青少年成长片段，无法概括整篇文章主旨，故排除。 二、补全对话：本题共5小题，每小题4分, 共20分。 A: Hi, Linda! You look happy today. Anything good? B: Yes! I just took part in a sharing activity in our community. 6________ A: Sounds great! 7________ B: I shared my second-hand books and some daily supplies with poor children. A: Wow, that’s very meaningful. 8________ B: Of course! Sharing not only cuts down waste but also helps others. I truly feel the happiness of sharing. A: I totally agree. We teenagers should learn to take responsibility for society. B: Exactly! 9________ Helping others can bring us special happiness. A: 10________ I will join the sharing activity next time. B: Welcome! Let’s spread sharing culture together. A. What did you do in the activity? B. I learned a lot and felt very happy. C. Do you think sharing is valuable? D. I used to care only about my own needs. E. Sharing makes our life warmer and better. F. It’s difficult for us to reduce pollution. G. Your experience inspires me a lot. 【答案】6.B 7.A 8.C 9.E 10.G 【导语】本段对话围绕社区分享活动展开，贴合单元主题，考查情景交际与上下文逻辑衔接，复现cut down waste、take responsibility、sharing culture等核心短语，句式简单地道，适配单元考试难度。 6. 【答案】B 【考点】情景交际（上下文语义承接） 【详细解析】上文表述“我参加了社区分享活动”，下文A回应“听起来很棒”，空处需要衔接活动后的感受。B选项“我收获很多，感到很开心”承接上文事件、引出下文夸赞，逻辑通顺。其余选项：A是问句、C是一般疑问句，不符合陈述句承接语境；D、F、G语义不匹配，直接排除。 7. 【答案】A 【考点】情景交际（问答匹配原则） 【详细解析】下文B详细回答了自己在活动中分享的物品和行为，属于具体事件作答，因此空处必须是询问“活动做了什么”的特殊疑问句，对应A选项。其余选项无法匹配下文具体行为的回答，问答逻辑断裂，予以排除。 8. 【答案】C 【考点】情景交际（一般疑问句问答呼应） 【详细解析】下文以 Of course（当然）进行肯定回答，并详细阐述分享的价值：减少浪费、帮助他人，由此可判断空处为一般疑问句，询问分享的意义与价值，对应C选项。其余选项均无法用Of course作答，问答不匹配。 9. 【答案】E 【考点】情景交际（观点总结升华） 【详细解析】上下文均在阐述分享的积极意义，前句认同分享的价值，后句说明助人能收获快乐，空处需要一句总结性观点衔接前后。E选项“分享让我们的生活更温暖、更美好”高度契合主旨，语义连贯。其余选项无总结升华作用，语境不符。 10. 【答案】G 【考点】情景交际（情绪递进衔接） 【详细解析】下文表述“我下次也要参加分享活动”，体现说话人被对方的经历感染、鼓舞。G选项“你的经历极大鼓舞了我”完美衔接该情绪递进。其余选项无法引出下文参与活动的决定，逻辑不通。 三、完形填空：本题共10小题，每小题4分, 共40分。 阅读下面短文，给出的四个选项中，只有一项符合题目要求。 Sharing is a special kind of happiness in our life.

A. increase B. cut C. raise D. produce 14. A. took B. joined C. attended D. played 15. A. Moreover B. However C. Otherwise D. Therefore 16. A. never B. hardly C. also D. too 17. A. If B. So C. But D. Though 18. A. difficult B. comfortable C. boring D. strict 19. A. ready B. responsible C. famous D. suitable 20. A. cheap B. simple C. valuable D. useless 【答案】11.A 12.A 13.B 14.A 15.B 16.C 17.A 18.B 19.B 20.C 【导语】本文围绕“分享的快乐”展开，贴合单元主题，重点考查单元核心短语、语境词义辨析、连词用法、固定搭配。覆盖care about、take responsibility、cut down waste、take part in、be responsible for等高频考点，句式贴合中职考纲，难度适配能力提升卷。 11. 【答案】A 【考点】单元核心固定短语辨析 【详细解析】care about 为单元必考短语，意为“关心、在意”。句意：分享教会我们关心他人、承担社会责任。固定短语区分：talk about（谈论）、worry about（担心）、think about（思考），均不符合“分享的内涵是关爱他人”的文章主旨，根据语境语义直接锁定A。 12. 【答案】A 【考点】单元固定短语搭配 【详细解析】become an adult 是单元标准固定短语，意为“成为成年人”，侧重成长身份的转变，适配语境。辨析干扰项：turn后直接接名词（无冠词）、get/grow侧重状态变化，不与an adult构成标准搭配，属于中式英语，故选A。 13. 【答案】B 【考点】语境动词辨析+单元短语延伸 【详细解析】cut 对应单元核心短语 cut down on waste（减少浪费）。句意：分享能够减少浪费，助力改善环境。干扰项：increase（增加）、raise（提升）、produce（产生）均与“环保、节约”的主旨完全相反，语义错误，直接排除。 14. 【答案】A 【考点】必考固定短语搭配 【详细解析】take part in 为单元唯一表示“参加活动”的固定搭配，特指参与群体性活动。辨析：join后接组织/人群、attend后接会议/课程、无play part in搭配，均不符合本句“参与分享活动”的语境，故选A。 15. 【答案】B 【考点】连词逻辑辨析（转折关系） 【详细解析】前句语义：我担心会失去个人物品（消极预期）；后句语义：结果远超预期、收获满满（积极结果）。前后语义相反，为转折关系，however（然而）符合逻辑。moreover（递进）、otherwise（否则）、therefore（因果）逻辑均不匹配，排除。 16. 【答案】C 【考点】副词用法辨析（位置规则） 【详细解析】also 用于句中实义动词前、系动词后，表“也”；too仅用于句末。本句空格在句中，表达“我也收获了自信”，故选C。never（从不）、hardly（几乎不）语义与文章积极主旨相反，直接排除。 17. 【答案】A 【考点】条件状语从句引导词 【详细解析】本句为条件逻辑：如果想要幸福生活，就要学会分享。if 引导条件状语从句，与单元短语as long as（只要）逻辑一致。so（因果）、but（转折）、though（让步）无法引导条件关系，语境语法均错误。 18. 【答案】B 【考点】形容词语境语义辨析 【详细解析】句意：分享让社会更温暖、更舒适。comfortable（舒适的、和谐的）贴合分享带来的积极社会氛围。干扰项：difficult（困难的）、boring（无聊的）、strict（严格的）均为消极词汇，与全文积极主旨相悖，直接排除。 19. 【答案】B 【考点】单元核心固定短语 【详细解析】be responsible for 为单元高频必考短语，意为“对……负责”。句意：每个人都应该为建设共享社会负责。be ready for（准备好）、be famous for（因……出名）、be suitable for（适合）均不符合“承担社会责任”的语境。 20. 【答案】C 【考点】形容词词义辨析+主旨理解 【详细解析】valuable 意为“珍贵的、有价值的”。句意：分享带来的精神快乐，远比单纯的物质快乐更珍贵。干扰项：cheap（廉价的）、simple（简单的）、useless（无用的）均与文章“分享极具价值”的核心主旨完全相反，予以排除。 四、句子改错：共10小题; 每小题2分，共20分。 21. Sharing various resources bring us warmth and precious happiness. ________ 【答案】bring → brings 【考点】主谓一致（动名词短语作主语） 【详细解析】语法核心规则：单个动名词/动名词短语作主语，统一视为单数主语，谓语动词必须用第三人称单数形式。本句主语Sharing various resources是单一动名词短语，因此谓语bring需改为brings。句意：分享各类资源为我们带来温暖与珍贵的快乐。 易错提醒：学生易误将复数名词resources当作主语，忽略真正主语是前置的动名词sharing。 22. A number of sharing activity helps students improve their sense of responsibility. ________ 【答案】activity → activities 【考点】a number of 固定用法 【详细解析】核心语法规则：a number of（许多）+ 可数名词复数，谓语动词用复数（本句helps为考点陷阱，适配复数名词语境）。activity为可数名词，单数形式不符合短语搭配规则，需改为复数activities。句意：许多分享类活动有助于提升学生的责任感。 易错提醒：区分a number of（许多，修饰复数名词）与the number of（……的数量，修饰单数谓语）。 23. We should learn to express gratitude for others’ kind help and care. ________ 【答案】for → to 【考点】单元固定短语搭配辨析 【详细解析】必考固定搭配：express gratitude to sb.（向某人表达感激）；无express gratitude for sb.用法。for多用于“因某事感激”，to用于“对某人表达感激”，本句对象是人，介词用to。 句意：我们应该对他人善意的帮助与关心表示感激。 易错提醒：介词搭配是单元高频改错考点，需精准区分to/for的用法场景。 24. The number of people who care about environmental improvement are growing. ________ 【答案】are → is 【考点】主谓一致（the number of 核心考点） 【详细解析】核心语法规则：the number of + 复数名词，主语核心词是number（单数），谓语动词固定用单数is。句中people是后置定语修饰number，并非真正主语。句意：关心环境改善的人数正在增加。 易错对比：a number of people（许多人，谓语复数）；the number of people（人数，谓语单数）。 25. Living on our own and sharing with others is important for teenagers. ________ 【答案】is → are 【考点】主谓一致（动名词并列结构） 【详细解析】语法规则：两个不同含义、独立的动名词短语并列作主语，指代两件不同的事物，视作复数主语，谓语用复数。本句“独立生活”和“与人分享”是两种不同的个人品质，因此is改为are。句意：独立生活和与人分享对青少年而言都很重要。 易错区分：若两个动名词指代同一事物、同一概念，才视作单数。 26. Many a student take part in public sharing activities every month. ________ 【答案】take → takes 【考点】主谓一致（many a 特殊结构） 【详细解析】特殊必考规则：many a + 单数名词，中文表“许多”，但语法形式为单数，谓语动词必须用第三人称单数。主语Many a student为单数结构，take改为takes。句意：许多学生每月都会参加公共分享活动。 易错提醒：该结构是中职主谓一致超高频率改错考点，切忌按中文语义判复数。 27. None of the sharing behaviors are useless in our daily life. ________ 【答案】are → is 【考点】主谓一致（none 用法规则） 【详细解析】考试标准规则：none 指代抽象事物、整体概念时，谓语动词用单数；只有指代具体可数人/物且强调个体时可用复数。本句none of the sharing behaviors指代“分享行为这件事”，为抽象整体，谓语用is。句意：日常生活中，所有分享行为都是有意义的。 28. Everyone should be responsible to protecting our living environment. ________ 【答案】to → for 【考点】固定短语搭配 【详细解析】单元核心固定搭配：be responsible for (doing) sth.（对……负责），无be responsible to doing结构。to后接动词原形，本句后置为protecting动名词形式，因此介词必须改为for。 句意：每个人都应负责保护我们的生活环境。 拓展：be responsible to sb.（对某人负责），介词搭配对象不同用法不同。 29. Cutting down on waste and reduce pollution are good social habits. ________ 【答案】reduce → reducing 【考点】并列结构形式一致原则 【详细解析】英语并列句硬性规则：and连接的并列主语，语法形式必须完全统一。前半部分为动名词Cutting down on waste，后半部分必须同样用动名词reducing，保持结构对称。句意：减少浪费、降低污染是良好的社会习惯。 易错提醒：并列结构不一致是改错经典陷阱，不看语义、只看语法形式统一。 30. As long as you keep sharing, you gain true happiness in return. ________ 【答案】gain → will gain 【考点】条件状语从句时态规则（主将从现） 【详细解析】as long as（只要）引导条件状语从句，严格遵循主将从现规则：从句用一般现在时（you keep），主句必须用一般将来时（will gain）。原句主句时态错误，不符合时态规则。句意：只要你坚持分享，就会收获真正的快乐。 规律总结：if/as long as/once引导的条件从句，均适用主将从现。 学科网（北京）股份有限公司 ( 1 )原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 $
