把鱼线抛向她父亲告诉她的那片水域。父亲告诉了她大鱼所在的具体“区域”，area“区域”符合。story“故事”、fish“鱼”、line“线”均与水的区域无关。2．句意：她和父亲已经期待社区钓鱼比赛好几个月了，钓上最大鱼的人能赢得丰厚奖品。根据“therewasabigprizefortheonewhocaughtthebiggestfish”可知他们一直期待的是“比赛”，competition“比赛”符合。chain“链条”与钓鱼无关，performance“表演”与钓鱼无关，ecosystem“生态系统”与比赛无关。3．句意：要有耐心。根据“Youcan’trushthefish”可知父亲提醒她钓鱼不能急，要“耐心”，patient“耐心的”符合。nice“好的”、quick“快的”、polite“礼貌的”均与耐心无关。4．句意：不要让赢奖毁了你的乐趣。父亲提醒她不要因为想赢而失去钓鱼的“乐趣”，fun“乐趣”符合。sense“感觉”、excitement“兴奋”、energy“能量”均与乐趣无关。5．句意：她父亲总是知道说什么让她振作起来。父亲的话让她“振作”起来，cheerup“使振作”，cheer“使振作”符合。mix“混合”、wake“醒来”、pick“挑选”均与振作无关。6．句意：有东西勾住我的鱼线了。根据“butitwouldn’tmove”可知鱼线拉不动，说明“卡住”了，stuck“卡住”符合。thrown“扔”、rushed“冲”、fixed“修理”均与卡住无关。7．句意：拉力特别大，她脑补着鱼线那头是自己见过最大的鱼。根据“sheimaginedthebiggestfishshe’deverseenontheendoftheline”可知鱼线那头拉力很大，说明鱼“很壮”，strong“强壮的”符合。beautiful“美丽的”、intelligent“聪明的”、tiny“微小的”均与拉力无关。8．句意：离岸边几英尺的地方，某个绿色的东西浮出水面。根据“thesurfaceofthewater.”可知绿东西“浮出”水面，brokethesurface“冲破水面”，指物体从水下钻出、露出水面，broke“打破”符合。attended“参加”、divided“分开”、doubled“加倍”均与浮出水面无关。9．句意：大家都围过来看Cindy的收获。根据“aroundtoseeCindy’scatch”可知是大家“围过来”看，gatheredaround“围过来”，gathered“聚集”符合。stared“盯着”、greeted“问候”、flashed“闪烁”均与围过来无关。10．句意：乌龟很大。后文说“Itmustbefortypounds”，说明乌龟“很大”，huge“巨大的”符合。valuable“有价值的”、comfortable“舒适的”、sleepy“困倦的”均与大小无关。11．句意：眼看乌龟就要拉上岸，父亲却出人意料地把它放生了。Cindy费力钓上来，本该欣喜，父亲却直接放生，行为超出她预料，surprisingly“出乎意料地”符合。normally“正常地”、proudly“骄傲地”、gradually“逐渐地”均与意外不符。12．句意：乌龟转身消失在了水面之下。根据“underthesurface.”可知乌龟“消失”在水中，disappeared“消失”符合。rose“上升”、reflected“反射”、lay“躺”均与消失不符。13．句意：大家来这儿钓鱼，只求能一睹它的身影。根据“Thatturtle’sbeeninthislakeforyears.Peoplecomefishingjusthopingto”可知裁判说这只乌龟在湖里很多年，大家钓鱼只求见到乌龟，不是捕捉，see“看见”符合。praise“表扬”、kick“踢”均与看见无关。catch“抓住”，比赛本意是钓鱼，这只乌龟大家只希望见到，不会捕捞，不符合语境。14．句意：比赛还没结束，但我心里有种预感，我知道谁能拿下“失之交臂的猎物”特别奖。根据“thatIknowwhoisgoingtowin”可知裁判说知道谁会赢，这是一种“预感”，feeling“感觉”符合，指内心预判、直觉，贴合裁判笃定知道获奖人选的语境。license“执照”、fame“名声”、mail“邮件”均与预感无关。15．句意：Cindy的眼睛亮了起来。得知有特别奖，Cindy的眼睛“亮了起来”，litup“亮起来”符合。shutoff“关闭”、tookoff“起飞”、gotup“起床”均与亮起来无关。16．A17．C18．B19．B20．B【导语】本文是一篇说明文，介绍了中国农村近年来发生的巨大变化，包括过去存在的问题、现在的改善以及仍面临的挑战。【解析】16．文章第一段描述了过去的村庄房屋老旧、道路泥泞、教育落后、父母外出打工等状况，直接说明该段主要讲过去村庄存在的问题。17．文章第二段提到“buildnewhousesandwideroads”、“Everyvillagehasitsownprimaryschool”、“sellfruitandvegetablesonline”，没有提到“村庄里没有老人”。直接说明C项不是村庄的变化。18．文章第三段指出“Theybringnewideasandtechnologytotheirhometown.Theyhelpvillagesdevelopfaster.”，直接说明年轻人回到家乡是因为他们发现了新的发展机会。19．文章第四段指出“Somevillagesareshortofyoungworkers.Oldpeoplestillneedmorepubliccare.”，这些都是需要解决的问题，由此推断“challenges”意为“挑战”。20．文章第二段指出“Thegovernmenthelpsbuildnewhousesandwideroads.”，直接说明政府在村庄变化中发挥了重要作用。21．C22．B23．B24．B25．C【导语】本文是一篇记叙文，主要讲述了上海工程师张伟放弃高薪工作，返回甘肃家乡，利用太阳能技术帮助村庄发展，改善农业和生活的故事。【解析】21．第一段明确提到“ZhangWeiisa32-year-oldengineerfromShanghai”，说明他回到家乡前的职业是工程师。22．第二段和第三段提到张伟“neverforgothishometown”并“oftenthoughtabouthowtohelpthevillagedevelop”，第三段明确说“hedecidedtogobackandbringchanges”，因此他返乡的原因是帮助村庄发展。23．根据第一段“In2020,hemadeabigdecision—helefthiswell-paidjobinthecityandreturnedtohishometown”可知，张伟于2020年回到家乡；结合第四段“Overthepastfouryears,thevillagehaschangedalot.”可知，文章描述的是回乡大约4年后的情况。因此，他已经回到家乡大约4年。24．根据第三段“Heoftenthoughtabouthowtohelpthevillagedevelop.”可知，他一直关心家乡的发展，体现了他的善良；根据第四段“ZhangWeiusedhisengineeringskillstobuildasmallfactorythatusessolarenergy.”可知，他利用工程技术建设太阳能工厂，体现了他的创造性。因此，张伟是一个善良且有创造力的人。25．第五段明确提到“Youngpeoplewholeftthevillagearestartingtocomebacktoworkinthenewfactory”，故选C。A项错误，文中使用的是太阳能（solarenergy）；B项错误，机器已替代人工挑水；D项错误，文中建的是学校，而非医院。26．B27．C28．B29．D30．A【导语】本文是一篇新闻类说明文（报道），通过临汾从重污染城市向绿色城市转型的案例，展现了环境治理和产业升级的成果，并以具体人物和时间为线索，结构清晰。【解析】26．由第1段末句“In2004,itwasnamedoneofthemostpollutedcitiesintheworld.”可知，答案为2004年。27．由第2段“In2025,Linfenhad321daysofgoodairquality,thehighestnumberinitshistory.”直接提取数字321。28．由第4段“45-year-oldWangGangusedtoworkinacoalmine.”可知，他过去在煤矿工作。29．由末段“By2030,thecityplanstofinishitstransitiontoa100%greenenergyeconomy.”可知，临汾将继续发展绿色能源。30．第①段总起，介绍临汾过去污染严重的旧面貌，作为背景铺垫；第②段讲城市治理举措与环境数据成果，第③段用游客LiJia的视角直观感受变化，第④段用煤矿工人转型案例体现民生改善，这三段共同属于“当下转变成果”的同一层级内容；第⑤段收尾，展望2030年绿色能源转型的未来规划。整体结构为“过去背景①→现状成果②③④→未来展望⑤”。31．G32．A33．D34．C35．B【导语】本文介绍了家乡在住房、交通、环境、生活等方面的巨大变化，展现了家乡的发展与人们生活水平的提高。【解析】31．由上文“Youmayfindthatgreatchangeshavetakenplacethere.”可知，此处应是介绍具体变化，下文提到“Thenarrowroadshavebecomewideandclean”，所以选项G“街道过去又窄又脏”，与下文形成了鲜明的“过去vs现在”对比，逻辑连贯。32．第二段主要讲述出行方式的变化——从步行/骑车到公交/汽车/高铁，所以选项A“最重要的变化在交通方面”是本段的主题句，概括了整段内容。33．第三段讲述环境改善。空白处后提到“Peoplehaveplantedmanytrees...”，这是具体的行动。选项D“Thegovernmenthastakenactiontoprotecttheenvironment”作为原因或总述，引出下文人们的具体行动和最终结果。选项E虽涉及环境，但与段末“wateriscleaner”内容重复，故D更佳。34．第四段主题是人们生活变好。空白处后列举了网购、医疗、上学等具体表现。选项C“他们现在有了新房子和更好的居住条件”中的“betterlivingconditions”是对下文具体生活改善内容的概括，且“They”指代段首的“People”。35．空白处位于文章末尾，前文详细描述了各项变化，后文总结这些变化连接了过去与现在。选项B“家乡的变化真令人惊叹”是对全文内容的总结和感叹，符合结尾段的语境。36．havediscovered【解析】句意：到目前为止，科学家们已经在深海发现了若干新物种。“Sofar”意为“到目前为止”，是现在完成时的标志性时间状语，现在完成时结构为“have/has+过去分词”；主语thescientists是复数，助动词用have，discover的过去分词为discovered。应填havediscovered。37．development【解析】句意：随着技术的发展，人们的生活正在快速变化。“withthedevelopmentof...”是固定搭配，意为“随着……的发展”。此处需填名词形式，“develop”是动词，其名词形式为development。38．tolive【解析】句意：过去人们常常住在又小又旧的房子里。usedtodosth.是固定搭配，表示“过去常常做某事”，用来描述过去曾经发生、现在已经不再发生的动作，to后面需要接动词原形。括号内给出的动词为live，意为“居住”，故填tolive。39．improvement【解析】句意：医疗保健的改善使人们活得更久。空格在定冠词the和介词of之间作主语，需要使用名词，improve是动词，对应的名词形式improvement表示“改善，提高”，因此填improvement。40．achievements【解析】句意：这些年他在学业上取得了巨大的成就。根据空格前形容词“great”，空格处需要填入名词。achieve是动词，表示“获得”，其名词形式为achievement，表示“成就”；固定搭配makegreatachievements表示“取得巨大成就”，常用复数形式。41．relatives【解析】句意：我有几个亲戚住在大城市里。句中“several”意为“几个”，后面需要接可数名词复数；relative“亲戚”，其复数形式为relatives。42．Communication【解析】句意：交流是一项非常重要的日常技能。空格后括号内的中文提示为“交流”，后续谓语动词是is，说明主语需要使用表示“交流”的名词形式，且为单数概念作主语，“Communication”作为名词意为“交流、沟通”，符合句子语法和语义要求，放在句首首字母需要大写。43．continue【解析】句意：他下周将继续他的旅行。根据汉语提示，表示“继续”的动词是continue，will是情态动词，后面必须接动词原形continue。44．abroad【解析】句意：许多年轻人想要出国留学。“在国外”对应的单词为abroad，studyabroad是固定短语，出国留学，abroad为副词，前面不能加介词。45．respect【解析】句意：我们应该尊重不同的观点。句中情态动词should后面需要接动词原形，respect表示“尊重”，故填respect。46．opportunityavailable【解析】中文“机会”对应英文单词opportunity/chance。在与动词catch搭配时，catchtheopportunity是初中英语中更常见的固定搭配。中文“可把握的”修饰“机会”。在英语中，当形容词修饰由every引导的名词短语时，常采用后置定语的形式。因此，“可把握的”译为available，并放在名词opportunity之后。故填：opportunity；available。47．Transportation/Trafficgreat【解析】原句关键词为“交通”和“很大程度”，分别用“Traffic/Transportation”和“great”表示（“great”与“a”“lot”构成“agreatlot”）。“Traffic”或“Transportation”作主语，hasimproved为现在完成时，agreatlot为程度副词短语修饰improved，整体表达“很大程度”。48．havetakenplace【解析】原句关键词“发生了”。takeplace表示“发生”，该短语没有被动语态；中文“发生了”体现动作已经完成，要用现在完成时，主语Greatchanges是复数形式，助动词选用have，take的过去分词为taken，构成havetakenplace的现在完成时结构，语义和语法均符合要求。49．Inthepastmedicaltreatment【解析】原句中“在过去”“医疗救治”是关键词，表示“在过去”的短语是inthepast；“医疗救治”是medicaltreatment。故填In；the；past；medical；treatment。50．hasbeentohasgoneto【解析】原句中“去过（已经回来）”、“去上海了（尚未回来）”是关键词，havebeento表示去过某地（人已返回）；havegoneto表示去了某地（人还未回来）。主语He和hisfather均为第三人称单数，助动词用has。因此应填①has；②been；③to；④has；⑤gone；⑥to。51．narrow52．in53．because54．rapidly55．reached56．millions57．grow58．their59．progress60．worse【导语】本文是一篇说明文，主要介绍了中国乡村在近年来发生的显著变化，包括基础设施的改善，生活水平的提升以及年轻人的回归。尽管现代生活带来了许多便利，但也有一些人怀念过去的简单生活。【解析】51．句意：道路狭窄且脏乱。此处与dirty并列作表语，说明道路环境不好，修饰Roads，结合备选词，narrow（狭窄的）符合语境，用原级。52．句意：房子很小且经常状况糟糕。结合“Housesweresmall”，此处表达“房子状况不好”，inbadcondition是固定短语，故填in。53．句意：一些孩子甚至不得不停止上学，因为他们的家庭太穷了。前后句是因果关系，后句解释原因，故填because。54．句意：然而，这些年事情改善得很快。根据后文“Thegovernmenthassupported...”，此处表达“改善迅速”，此处修饰动词improved，需用rapid的副词形式rapidly。55．句意：乡村已经达到了一个新的发展水平。has提示现在完成时，后接过去分词，表示“达到”，reach变为reached。56．句意：现在，数以百万计的人住在现代房子里。millionsof是固定短语，意为“数以百万计的”，故填millions。57．句意：农民使用机器种植庄稼。根据“Farmers”，此处表达“种植庄稼”，to后接动词原形表目的，growcrops意为“种植庄稼”，故填grow。58．句意：另一个显著的变化是，许多曾经离开他们村庄去城市工作的年轻人如今选择返乡。此处修饰名词villages，指代youngpeople，需用they的形容词性物主代词their。59．句意：甚至多年前搬走的亲戚也回来参观，并对进步感到惊讶。the后接名词，结合上文提到的变化，progress（进步）符合语境。60．句意：当然，过去的一切并不都比现在更糟。than提示用比较级，bad的比较级是worse，符合下文提到的“过去生活更简单”的对比语境。61．it62．others63．developed64．havecollected65．also66．except67．busiest68．connection69．yet70．carefully【导语】本文介绍了曾因屋顶漏雨被闲置的河滨阅览室，由居民发起改造后重新焕发生机，如今成为社区热门的公共阅读与交流空间，既满足了不同群体的文化需求，也拉近了邻里之间的距离。【解析】61．句意：两年前，一群居民决定让它重获生机。此处指代前文出现的“TheRiversideReadingRoom”，单数事物，用代词it。62．句意：一些人想要儿童读物，另一些人则希望有一处安静的自习区。固定搭配some...others...，表示“一些人……另一些人……”，填others。63．句意：随后社区制定了修缮方案。叙述两年前发生的事情，时态为一般过去时，使用develop的过去式developed。64．句意：自去年春天以来，志愿者们已经收集了三千多本书。“Sincelastspring”是现在完成时标志，主语volunteers为复数，助动词用have，后跟动词过去分词collected。65．句意：还增设了一处小型数字阅览区，老年居民可以在此学习使用线上服务。前文修缮房屋、收集书籍，此处表示额外增添设施，also意为“也、还”，放在助动词之后。66．句意：这间阅览室除周一之外，每日开放。此处表示“除了周一之外这个阅览室每天都开放”，except表示“除了……（不包含在内）”，符合语义。67．句意：它已然成为小区里最热闹的场所之一。固定结构“oneofthe+形容词最高级+名词复数”，表示“最……之一”，busy的最高级为busiest。68．句意：这个项目也在邻里之间建立起了更强的联结感。介词of后需要名词，connect是动词，其名词形式为connection“联系、联结”，senseofconnection“归属感、联结感”。69．句意：还没有。固定表达notyet表示“还没有、尚未”，对应前文“所有问题都消失了
