Fight Against a Disastrous Flood A terrible disaster once struck our town, a disastrous flood that began to flood low-lying areas overnight. Soon roads were flooded, and widespread flooding swept across the whole district. Local officials decided to evacuate residents at once, and the whole evacuation process was carried out in order. Many buildings suffered heavy damage; walls were damaged, and the damaging water flow would completely destroy houses, bringing total destruction with its destructive force. The disaster seriously affected daily life, and its terrible effect proved that early warning was highly effective. Thick water made walls crack, leaving countless cracked walls and houses in ruin, most of which became totally ruined. The sudden scene gave people a great shock. Everyone looked shocked at the shocking sight. The electricity supply was cut off: no electric lights, broken electrical wires and broken electronic devices lay everywhere. Many elders were trapped in buildings, so professional rescuers rushed to rescue them without hesitation. Some victims were buried under broken bricks; workers carried out proper burial for the dead later. People could hardly breathe, their short breath making them breathless. Doctors tried their best to revive the weak, and many patients were fully revived, bringing hope of a full revival. Lots of local people suffered great pain. Their endless suffering touched every volunteer and each disaster sufferer felt hopeless. A nearby volcano might erupt as well, and a possible eruption meant more eruptive risks. Charities came to supply food and daily supplies, with many kind suppliers donating goods for free. Only a few people managed to survive the flood. Their survival story inspired all other survivors. Cut off from power, people felt powerless without this powerful resource. When such an emergency appears, we must face these emergent dangers with a calm mind, act calmly and keep inner calmness. The disaster continued to strike the town, with a striking number of houses destroyed; local strikers even stopped work temporarily. Volunteers deliver supplies day and night, and each fast delivery relies on hard-working deliverers. United efforts finally helped the town pull through the tough crisis. 翻译短文并提取本单元核心词汇,写出词性转换、含义 Part 2. Unity Lights Up Hope in Disasters（灾难同心，点亮希望） When a sudden natural disaster hits a coastal town, most residents are in shock. The fierce destruction is a great shock to every villager, who are deeply shocked at the chaotic scene. Many people run for survival, soon out of breath and even losing their breath in panic. To calm themselves down, they take a deep breath and breathe deeply, trying to breathe freely amid chaos instead of staying desperate. Some villagers unconsciouslyhold their breath, waiting anxiously for rescue. The disaster caused a sudden power failure. Since the ruling party once came to power with the purpose of benefiting people, relevant departments spare no effort and make every effort to carry out rescue work. Volunteers also make joint efforts to assist victims and never make no effort to help those in need. They work with effort rather than finishing tasks without effort. With limited manpower beyond individual power, people rely on collective strength, for no one alone has the power to reverse the disaster. The disaster left daily necessities in short supply. Local charities supply residents with food and daily goods, which offers a good supply of materials for rescue. With the aid of professional rescuers, volunteers aid villagers in disaster relief and aid them to rebuild homes. All efforts have a positive effect on disaster recovery and soon come into effect officially. It suddenly strikes people that unity conquers all hardships. Some villagers are buried in sorting disaster data instead of complaining. To survive on tough conditions and survive from the catastrophe, they stick together. In summary, a brief summary of the disaster teaches us that powerful unity turns powerless individuals into an unbreakable force. Choose the best answer for each question. 1. What do some villagers do to deal with panic after the disaster? A. They keep holding their breath all the time. B. They try to adjust their breathing to calm down. C. They run continuously to avoid danger. D. They wait for rescue in total despair. 2. What can we infer about the rescue work from Paragraph 2? A. It depends entirely on professional rescuers. B. Individuals are powerful enough to stop the disaster. C. Rescue workers devote themselves whole-heartedly. D. Volunteers finish rescue tasks effortlessly. 3. Which of the following is true according to the passage? A. The charity materials fail to support rescue work. B. Collective help promotes post-disaster recovery. C. Daily goods are still abundant after the disaster. D. Rescue measures take effect very slowly. 4. What is the main message of the last paragraph? A. Hardships can shape people’s strong will. B. Villagers are good at sorting out disaster data. C. Individual ability matters most in disasters. D. Unity makes weak people powerful in disasters. 翻译短文并提取文中出现的本单元核心短语，按类别补充完整，注意标注词性和核心含义 翻译下面的句子： 1. 我们静静屏住呼吸，期待一份美好的惊喜。 2. 年少时我们应当不遗余力地实现梦想。 3. 父母和学校为我们提供支持与宝贵的指导。 4. 每个人都有能力通过坚持改变自己的人生。 5. 在现代科技的帮助下，我们学习效率更高。 6. 真正的朋友总会帮助我们战胜生活中的困境。 7. 我深深被人们的坚持与乐观所打动。 8. 我突然意识到时光不等人，理应被珍惜。 9. 日常习惯对我们的成长和未来影响巨大。 10. 许多人对公共资源的浪费现象感到震惊。 11. 我震惊地发现普通人也可以拥有巨大的力量。 12. 为提升自我，她每天潜心阅读、勤于思考。 13. 唯有保持坚强，我们才能挺过各种挑战。 Part 3. Stay Alert for Natural Disasters Natural disasters come in various forms, including tornadoes, droughts, tsunamis, volcanoes, typhoons and hurricanes. Some strike suddenly with great magnitude, while others develop gradually over time. Severe storms often trigger floods or landslides, making rocks and soil slide down steep hills and destroy nearby buildings. When a disaster breaks out, local facilities usually suffer severe damage. Many houses develop cracks or are completely destroyed. Piles of bricks and metal materials lie on the ground, and broken pipes leak gas, putting people in danger. In a short time, whole villages fall in ruins, leaving residents in shock. Unlike daily accidents, such emergencies require timely and professional treatment. Once an emergency occurs, rescue teams arrive promptly with professional kits. Workers evacuate trapped residents and send supplies on hand. Sometimes helicopters are used for air rescue to save more lives. Cleaners sweep away ruins and obstacles to restore order. Though disasters ruin property and destroy up to 50 percent of local infrastructure, people unify to fight against hardships. We cannot live in the open air when disasters approach. If we stay alert and cooperate, the sufferings will finally come to an end. This is the true context of disaster relief: unity overcomes all crises. 翻译短文并写出黑体词的词性，词义 单句语法填空： 1.

B 【细节理解题】 解析：根据第一段“they take a deep breath and breathe deeply, trying to breathe freely amid chaos”可知，村民通过调整呼吸平复恐慌情绪。A项“一直屏住呼吸”、C项“持续奔跑避险”、D项“绝望等待”均与原文不符。 2. C 【推理判断题】 解析：第二段提到相关部门 spare no effort（不遗余力）、志愿者make joint efforts（同心协力），可推知救援人员全心投入救灾。A项完全依赖专业人员、B项个人可抵御灾难、D项志愿者轻松完成任务均与原文相悖。 3. B 【细节辨析题】 解析：第三段表明各界援助对灾后恢复产生积极效果并迅速落地生效，印证集体帮扶助力灾后重建。A项物资未起到作用、C项物资依旧充足、D项措施生效缓慢均错误。 4. D 【主旨大意题】 解析：尾段核心句“powerful unity turns powerless individuals into an unbreakable force”点明主旨：团结让弱小的个体拥有强大力量，战胜灾难。A项偏离段落核心、B项为细节举例、C项与文意相反。 当突如其来的自然灾害席卷滨海小镇，大部分居民陷入震惊之中。惨烈的灾情让所有人倍感错愕，人们为混乱的场面深深震撼。不少人奔逃求生，很快气喘吁吁、几近窒息。为平复心绪，他们深呼吸、舒缓气息，在慌乱中努力稳住状态、从容自救，而非一味消沉。部分村民下意识屏住呼吸，焦急等待救援。灾害导致突发停电。秉持为民初心执政的相关部门，不遗余力开展救援工作。志愿者们同心协力帮扶灾民，从未懈怠分毫，始终奋力奔走、辛苦付出，绝不敷衍了事。个人力量有限、力所不及，唯有集体聚力，方能抗衡灾难。灾区生活物资供应短缺，当 地慈善机构为居民输送物资，保障救援物资充足供给。在专业救援人员的协助下，志愿者助力灾民开展救灾、重建家园。所有救援举措都对灾后恢复产生积极影响，并迅速正式落地生效。人们突然意识到，团结可战胜万难。部分村民潜心整理灾情资料、默默付出。为在困境中立足、从灾难中重生，众人抱团坚守。总之，这场灾难的简要总结告诉我们，强大的凝聚力能让弱小的个体凝聚成坚不可摧的力量。 短语：breathe out 呼气；out of breath 喘不过气；breathe freely感到自在，轻松自在 breathe in/out 吸气/呼气 breathe deeply 深呼吸 (2) breath n. 呼吸；气息 take a (deep) breath （深）呼吸 hold one’s breath 屏住呼吸 out of breath 上气不接下气 lose one’s breath 喘不过气来 \ spare no effort 不遗余力；joint effort 共同努力；effort to do 努力做…… make efforts/ an effort to do... 努力做…… make no effort to do... 没努力做…… spare no effort to do sth 不遗余力做某事 = make every effort to do sth with effort 吃力地 without effort 毫不费力地 supply with 供应；in short supply 供应短缺 in short supply 短缺 a good supply of… …的充足供应 supply sb with sth = supply sth. to sb 向某人提供某物 = provide sb with sth = provide sth for sb = offer sb sth = offer sth to sb in power 掌权；come to power 上台；power failure 停电 come to/into power 掌权；上台 (be) in power 当权；执政 beyond one’s power 力所不能及 have the power to do sth. 具有做某事的能力 (2) powerful adj. 强有力的；有权势的；有影响力的 (3) powerless adj. 无力的；没有能力的 aid sb. in 帮助某人…… with the aid of 在……的帮助下 in aid of 为了帮助…… aid sb in sth 帮助某人某事 aid sb to do sth 帮助某人做某事 be struck by 被……打动 strike sb on/in+the+身体部位 打某人某部位 be struck by 被……打动 sth strikes sb = it strikes/hits/occurs to sb that…某人突然想起… (2) be/go on strike 在罢工 in summary 总之；make a summary 做总结；a brief summary 简要总结 take effect 生效；have an effect on 对……有影响；come into effect 开始生效 ·in shock　　　　　　　　 震惊;吃惊 be a great shock to sb 对某人来说是件震惊的事情 ·be shocked at sth/that... 对……感到震惊 be shocked to do sth 因做某事而感到震惊 　　　　　 　 埋头于;专心于 bury one’s face in one’s hands 双手掩面 survive from...　　 从……中存活下来 survive on... 依靠……生存下来 survive...by... 比……多活了…… 翻译下面的句子： 1. hold one’s breath 屏住呼吸 We hold our breath quietly, hoping for a pleasant surprise. 我们静静屏住呼吸，期待一份美好的惊喜。 2. spare no effort to do sth 不遗余力做某事 We should spare no effort to realize our dreams in youth. 年少时我们应当不遗余力地实现梦想。 3. supply sb with sth 为某人提供某物 Parents and schools supply us with support and valuable guidance. 父母和学校为我们提供支持与宝贵的指导。 4. have the power to do sth. 具有做某事的能力 Everyone has the power to change their life with constant efforts. 每个人都有能力通过坚持改变自己的人生。 5. with the aid of 在……的帮助下 With the aid of modern technology, we study more efficiently. 在现代科技的帮助下，我们学习效率更高。 6. aid sb to do sth 帮助某人做某事 True friends always aid us to overcome difficulties in life. 真正的朋友总会帮助我们战胜生活中的困境。 7. be struck by 被……打动 I am deeply struck by people’s persistence and optimism. 我深深被人们的坚持与乐观所打动。 8. it strikes sb that… 某人突然想起…… It strikes me that time waits for no one and should be treasured. 我突然意识到时光不等人，理应被珍惜。 9. have an effect on 对……有影响 Daily habits greatly have an effect on our growth and future. 日常习惯对我们的成长和未来影响巨大。 10. be shocked at sth 对……感到震惊 Many people are shocked at the waste of public resources. 许多人对公共资源的浪费现象感到震惊。 11. be shocked to do sth 因做某事而感到震惊 I am shocked to find how powerful ordinary people can be. 我震惊地发现普通人也可以拥有巨大的力量。 12. be buried in 埋头于；专心于 To improve herself, she is buried in reading and thinking every day. 为提升自我，她每天潜心阅读、勤于思考。 13. survive from... 从……中存活下来/挺过来 Only by staying strong can we survive from various challenges. 唯有保持坚强，我们才能挺过各种挑战。 Part 3. 警惕自然灾害（全文中文翻译） 自然灾害种类繁多，包括龙卷风、旱灾、海啸、火山、台风以及飓风。部分灾害震级高、突发迅猛，另有一些灾害则缓慢酝酿形成。强风暴往往会引发洪水或山体滑坡，导致山石泥土沿陡坡滑落，损毁周边建筑设施。 灾害发生时，当地设施通常会遭受严重损毁。大量房屋出现裂缝，甚至被彻底摧毁。遍地散落着砖块与金属建材，破损的管道发生燃气泄漏，极大威胁着民众安全。顷刻间，整座村落破败不堪，居民们陷入极度震惊的状态。这类突发事件不同于日常意外，需要及时、专业的处置与救援。 一旦紧急灾情发生，救援队会携带专业成套设备迅速抵达现场。工作人员紧急疏散被困群众，调配现有物资支援救灾，有时还会出动直升机开展空中营救，挽救更多生命。工作人员清理废墟、扫除障碍，逐步恢复秩序。尽管自然灾害会毁坏财物，损毁高达百分之五十的当地基础设施，但人们凝心聚力、众志成城，共同对抗灾难带来的困境。 灾害来袭时，人们无法在露天环境中避险求生。只要我们保持警惕、团结协作，灾难带来的苦难终会落幕。这便是救灾减灾的核心要义：众志成城，无坚不摧。 1.tornado n.(pl.-oes or -os)龙卷风;旋风 2.drought n.旱灾;久旱 3.landslide n.(山地或悬崖的)崩塌;滑坡 4.slide vi.& vt.(slid,slid)(使)滑行;滑动 5.tsunami n.海啸 6.magnitude n.震级;重大 7.evacuate vt.疏散;撤出 8.helicopter n.直升机 9.unify vi.& vt.统一;(使)成一体 10.volcano n.(pl.-oes or -os) 火山 11.typhoon n.台风 12.hurricane n.(尤指西大西洋的)飓风 13.kit n.成套工具;成套设备 14.disaster n.灾难;灾害 15.rescue n.& vt.营救;救援 16.damage vt.损害;破坏n.损坏;损失 17.destroy vt.摧毁;毁灭 18.crack n.裂纹;裂缝vi.& vt.(使)破裂 19.gas n.气体;燃气;汽油 20.ruin n.& vt.破坏;毁坏 21.percent n.百分之…… adj.& adv.每一百中 22. brick n.砖;砖块 23. metal n.金属 24. context n.上下文;语境;背景 25.pipe n.管子;管道 26. emergency n.突发事件;紧急情况 27.crash vt.& vi.碰撞;撞击;(计算机)崩溃n.撞车;碰撞 28.sweep vt.& vi.(swept,swept)打扫;清扫 29.flood n.洪水;大量vi.淹没;大量涌入vt.使灌满水;淹没 30. shelter n.避难处;居所;庇护vt.保护;掩蔽vi.躲避(风雨或危险) 31.tap vi.& vt.轻叩;轻敲;轻拍n.水龙头;轻叩;轻敲 32. whistle vi.吹口哨;发出笛声vt.吹口哨n.哨子(声);呼啸声 33. as usual像往常一样 34. come to an end结束 35.in ruins严重受损;破败不堪 36. in shock震惊;吃惊 37. in the open air露天;在户外 38. on hand现有(尤指帮助) 39. sweep away 消灭;彻底消除 单句语法填空 【答案】1.disastrous, disaster;
