2025年新视野二册课后练习答案一、Unit1课后练习答案与解析（一）VocabularyandStructure1.选词填空（从方框中选择正确单词并用适当形式填空）（1）答案：sustainable解析：根据语境"effortstobuilda___community"（建设____社区的努力），需填入形容词修饰"community"。"sustainable"意为"可持续的"，符合"环保、长期发展"的语义，与后文"reducecarbonfootprint"（减少碳足迹）逻辑一致。（2）答案：initiatives解析："launchseveral___topromotelocalculture"（发起多项____以推广本土文化）中，"launch"后接可数名词复数，"initiatives"（倡议/举措）为复数形式，强调具体行动，符合"推广文化"的语境需求。（3）答案：interdependent解析："modernsocietiesareincreasingly___"（现代社会日益____）需形容词作表语。"interdependent"（相互依赖的）体现全球化背景下社会间的紧密联系，与后文"nocountrycandevelopinisolation"（没有国家能孤立发展）形成因果关系。2.语法填空（根据句子结构填入适当的词或时态）（1）答案：hadbeenworking解析："Bythetimethemanagerarrived,theteam___(work)ontheprojectfor12hours"（经理到达时，团队已为项目工作12小时）。"bythetime+一般过去时"引导的时间状语从句，主句需用过去完成进行时（hadbeendoing），强调动作从过去某一时间开始持续到另一过去时间，且可能仍在进行。（2）答案：where解析："Thesmalltownhastransformedintoatouristhub___traditionalcraftsmeetmodernart"（小镇已转变为旅游中心，____传统工艺与现代艺术交融）。空格处引导定语从句修饰"hub"（中心），先行词表地点，从句缺状语，故用关系副词"where"。（3）答案：havingbeeninvited解析："___(invite)todeliveraspeechattheinternationalconference,shespentweekspreparingthecontent"（____在国际会议上演讲，她花数周准备内容）。主句主语"she"与"invite"为被动关系，且"邀请"发生在"准备"之前，故用现在分词完成被动式"havingbeeninvited"作状语。（二）ReadingComprehension（PassageA）1.细节题：Whatisthemainchallengementionedinthepassageregardingurbangreenspaceplanning?答案：Themismatchbetweenrapidurbanizationandtheslowpaceofgreenspaceexpansion,leadingtoinsufficientaccessforlow-incomecommunities.解析：文中第二段明确指出"Whilecitiesexpandatanannualrateof3.2%,theareaofpublicgreenspacesgrowsbyonly1.1%,withthemostunderservedpopulationsbeingthoseinlow-incomeneighborhoods"（城市以3.2%的年增长率扩张，公共绿地仅增长1.1%，低收入社区是最缺乏绿地的群体），核心矛盾是扩张速度不匹配及资源分配不均。2.推断题：Whydoestheauthormention"pocketparks"inParagraph3?答案：Toillustrateapracticalsolutionforoptimizinglimitedurbanlandtoprovideaccessiblegreenspaces.解析：第三段提到"pocketparks（袖珍公园）"时，具体说明其"occupyinglessthan0.5hectaresbutservingover500residentswithina10-minutewalk"（占地不足0.5公顷，却能服务10分钟步行范围内500多居民），目的是通过实例证明在有限土地上也能高效增加绿地，解决前文提出的空间不足问题。3.主旨题：Whatisthepassagemainlyabout?答案：Theimportanceofintegratinggreenspaceplanningintourbandevelopmenttoensureequitableaccessandenvironmentalsustainability.解析：全文结构为"提出问题（绿地增长滞后于城市化）—分析影响（低收入群体受影响大）—举例解决方案（袖珍公园、屋顶花园）—强调意义（生态与社会公平）"，核心围绕绿地规划与城市发展的结合及其必要性展开。（三）Translation（汉译英）原句："近年来，社区图书馆不仅成为居民获取知识的场所，更演变为促进邻里交流、传承地方文化的重要平台。许多图书馆通过举办读书会、手工艺工作坊和方言故事会，让不同年龄层的居民在互动中加深了解，共同守护文化记忆。"参考译文：Inrecentyears,communitylibrarieshavenotonlyservedasplacesforresidentstoaccessknowledgebutalsoevolvedintocrucialplatformsforpromotingneighborhoodcommunicationandinheritinglocalculture.Manylibrariesorganizereadingclubs,handicraftworkshops,anddialectstorytellingsessions,enablingresidentsofallagestodeepenmutualunderstandingthroughinteractionandjointlysafeguardculturalmemories.解析：翻译时注意以下几点：①"不仅…更"译为"notonly…butalso"，突出递进关系；②"演变为"用"evolvedinto"准确传达动态变化；③"促进邻里交流"处理为"promotingneighborhoodcommunication"，"传承地方文化"译为"inheritinglocalculture"，保持动宾搭配自然；④"举办读书会、手工艺工作坊和方言故事会"译为"organizereadingclubs,handicraftworkshops,anddialectstorytellingsessions"，动词"organize"涵盖多种活动；⑤"让…加深了解"用"enabling…todeepenmutualunderstanding"，分词结构衔接紧凑；⑥"共同守护文化记忆"译为"jointlysafeguardculturalmemories"，"jointly"强调集体行动，"safeguard"比"protect"更贴合"守护"的文化内涵。二、Unit2课后练习答案与解析（一）VocabularyandStructure1.词义辨析（选择与划线词最接近的选项）（1）Theresearcherhighlightedtheurgencyofaddressingplasticpollutionincoastalareas.A.overlookedB.emphasizedC.doubtedD.dismissed答案：B解析："highlighted"意为"强调"，与"emphasized"（强调）同义；"overlooked"（忽视）、"doubted"（怀疑）、"dismissed"（驳回）均不符合语境。（2）Thenewpolicyaimstostreamlinetheprocessofapplyingforsmallbusinessloans.A.complicateB.simplifyC.delayD.monitor答案：B解析："streamline"意为"简化（流程）"，与"simplify"（简化）同义；"complicate"（复杂化）为反义词，"delay"（延迟）、"monitor"（监控）无关。2.句型转换（根据要求改写句子）原句：Thegovernmenthasintroducedaseriesofmeasures.Thesemeasuresareintendedtoreduceyouthunemployment.（合并为含定语从句的复合句）答案：Thegovernmenthasintroducedaseriesofmeasureswhich/thatareintendedtoreduceyouthunemployment.解析：合并时需用关系代词"which/that"引导定语从句修饰"measures"，原句中的"Thesemeasures"转换为从句主语，保持逻辑连贯。（二）ReadingComprehension（PassageB）1.态度题：Whatistheauthor'sattitudetowardstheuseofAIinlanguageteaching?答案：Cautiouslypositive.解析：文中既肯定AI"canprovidepersonalizedfeedback,adapttolearners'progress,andoffer24/7practiceopportunities"（能提供个性化反馈、适应学习进度、提供全天候练习），又指出"over-reliancemayweakenhumaninteraction,akeyfactorinlanguageacquisition"（过度依赖可能削弱人际互动——语言学习的关键因素），体现"谨慎乐观"的态度。2.细节题：Accordingtothepassage,whatisalimitationoftraditionallanguageteachingmethods?答案：Theyoftenadoptaone-size-fits-allapproach,failingtomeetthediverseneedsoflearnerswithdifferentproficiencylevelsandlearningstyles.解析：第三段明确提到"Traditionalclassrooms,constrainedbyfixedcurriculaandclasssizes,struggletotailorinstructiontoindividuallearners.Abeginnerandanadvancedstudentmayreceivethesamelesson,leadingtoinefficiency"（传统课堂受固定课程和班级规模限制，难以针对个体调整教学。初级和高级学生可能接受相同课程，导致低效），核心限制是"一刀切"的教学方式。3.推理题：WhatcanbeinferredaboutthefutureofAIinlanguageeducation?答案：Itwilllikelycomplementratherthanreplacehumanteachers,withafocusonbalancingtechnologicalsupportandhumaninteraction.解析：末段指出"EducatorsshouldviewAIasaco-teacher,notasubstitute.TheidealmodelcombinesAI'sdata-driveninsightswithteachers'emotionalsupportandculturalguidance"（教育者应将AI视为协同教师而非替代者。理想模式是AI的数据驱动洞察与教师的情感支持、文化引导相结合），可推断未来AI将作为补充而非替代。（三）Writing（短文写作：以"DigitalLiteracyintheAgeofInformation"为题，写一篇150词左右的短文）参考范文：Intheinformationage,digitalliteracyhasbecomeafundamentalskillforeveryone.Itrefersnotonlytotheabilitytousedigitaltoolslikesmartphonesandcomputersbutalsotocriticallyevaluateonlineinformation,protectpersonaldata,andcommunicateresponsiblyinvirtualspaces.Withoutadequatedigitalliteracy,individualsmayfallvictimtomisinformation,suchasfakenews
