使用它。根据后文“Ithelpsustoeasilyknowaboutsomeinformationofproducts.”，帮助获取信息，可知是被使用（used）。repaired修理，tried尝试，learned学习，不符合普及后的状态。16．B17．C18．D19．C20．A【导语】本文主要讲述了印度少年Aarrav为帮助患有帕金森病的叔叔解决进食困难而发明智能勺子的故事。【解析】16．根据第一段“Hesawhisuncle,whohasParkinson’disease(PD)(帕金森病),strugglingtofeedhimself.Foodkeptfallingoutofhismouth,makinghimlooklikeamess”和第三段“Aarravwantedhisuncletobeabletoeatbyhimself”可知，阿拉夫看到患有帕金森病的叔叔挣扎着喂他自己。食物不停地从他嘴里掉出来，弄得一团糟，以及后文提到阿拉夫希望他的叔叔能够自己吃饭，故此处应表示他想做出改变，改变叔叔现在这种情况，选项B“他想要做出改变。”符合语境。17．根据第一段“Hesawhisuncle,whohasParkinson’sdisease(PD)(帕金森病),strugglingtofeedhimself.”及后文“ Foodkeptfallingoutofhismouth,”可知，他的叔叔患有帕金森病，所以应是在吃饭时是行动不便的，所以划线单词表示“做某事有困难”。18．文章第四段“ItwasdisappointingnottobeabletofindcertainpartsIneededinIndia.Ihadtobuysomefromabroad”指出，他遇到的问题是部分所需物品在印度本地无法买到。19．文章第五段主要讲述了Aarrav对智能勺子所做的改进，包括防水、易分离、勺子更深等。因此本段主要讲的是Aarrav所做的改进。20．全文围绕擅长机械的少年Aarrav为帮助帕金森病患者研发智能辅助勺的事件展开，A项精准覆盖核心人物、发明对象与服务群体。21．B22．B23．D24．C25．D【导语】本文是一篇说明文，主要介绍了中国四大发明之一——造纸术的发展历史及其对世界的深远影响。【解析】21．文章开头先点明造纸术是中国古代的伟大发明，接着用“Beforeitscreation,peopledependedonheavybambooslips,expensivesilk,orhardanimalbones…”与后来轻便、便宜的纸张形成对比，突出造纸术带来的巨大改变，因此是通过对比来引入主题的。22．梳理全文线索，文中依次出现“Beforeitscreation（纸发明前）”“WesternHanDynasty（西汉）”“EasternHanDynasty（东汉）”“laterspreadtoothercountries（之后传播到其他国家）”“Eventoday（如今）”等时间节点，是按照时间顺序展开叙述的。23．由第二段“thequalitywasnotgoodenoughfordailyuse”可知，西汉早期纸张的质量不足以用于日常使用。24．由第三段“Thischangemadepapercheaperandmorepractical”可知，蔡伦的改进使纸张更便宜、更实用，从而普及。25．由最后一段“Papermakinglaterspreadtoothercountriesthroughtradeandculturalexchange”可知，贸易帮助造纸术传播到全球，选D。A项错误，由“ItfirstreachedAsiancountries,thenspreadtoEurope”可知，造纸术首先传到亚洲国家，然后才传到欧洲；B项错误，由“thenspreadtoEurope,andfinallytoallpartsoftheworld”可知，造纸术传播到了欧洲和世界各地，不仅限于亚洲；C项错误，由“Eventoday,paperremainsanimportantpartofourdailylife”可知，纸张至今仍在日常生活中发挥着重要作用。26．D27．B28．C29．A30．D【导语】本文讲述了一个青少年团队在48小时编程活动中，通过聚焦用户真实痛点，放弃宏大计划，最终开发出一款简单实用工具的故事。【解析】26．根据第一段“plannedanappthatwouldidentifyeverydifficulty...Sixhourslater,theyhadabeautifulscreenandalmostnothingthatworked”可知，他们最初的计划过于宏大（识别所有困难、制定完整计划），导致在规定时间内无法完成实质功能。选项D“想法太广泛，无法在可用时间内构建出有用的东西”符合文意。27．根据第二段“usershadtoopeneachwronganswerseparatelybeforetheycouldseethetypeofmistake”可知，采访中发现的重复问题是用户必须单独打开每个错误答案才能查看错误类型，非常耗时。选项B“用户花费太多时间逐个打开错误”表述正确。28．根据第三段“Theprogramdidnotdecidewhyananswerwaswrong;teacherscreatedthelabelwhentheywrotethequestion”可知，错误类型是由出题老师在编写问题时创建标签决定的，而非程序本身。选项C“创建问题的老师”符合文意。29．根据第四段“testersspentlesstimefindingmistakesandmoretimecorrectingthem”可知，测试者花更少时间找错，更多时间改错，说明工具提高了纠错效率。选项A“它使纠错过程更高效”符合文意。30．根据最后一段“NowIthinkitcanmeanprotectingtheonefunctionthatsolvestherealproblem”可知，她认识到野心不在于增加功能，而在于保护能解决真正问题的那个功能。选项D“一个专注的解决方案比许多令人印象深刻的功能更有价值”符合这一感悟。31．E32．C33．D34．F35．G【导语】本文以冰箱为线索，按照时间顺序介绍了冰箱诞生前从古至今人类储存食物的各类方法，以及现代冰箱不断升级的发展历程。【解析】31．前文“Thefirstelectricrefrigeratorwasmadein1913.”介绍第一台电冰箱诞生于1913年，后文讲述古代人依靠冰雪、日晒来储存食物，空处起到转折过渡作用，引出冰箱诞生前的储食方式。E项“Beforethen,peoplefoundotherwaystostoretheirfood.”中then指代1913年，说明在电冰箱出现前人们有其他储存食物的办法，衔接前后古今储食内容。32．前文介绍中世纪人们通过腌制、熏制、风干等方式处理食物，再将食物存放于阴凉处，空处总结这类储存方式带来的好处。C项“Thisallowedpeopletosavefoodintimesofneed.”表示这些方法让人们可以储备食物以备不时之需，承接前文各类食物保存手段。33．前文“Later,buildingscalledicehousesoricepits(坑)werebuiltbasedontheideaoftheYakhchal.”引出冰窖、冰屋，后文“Alargerabove-groundbuildingcoveredthepit.”介绍地面建筑遮盖冰坑，空处说明冰窖的制冷原理。D项“Theywerecooledbyanundergroundpitfullofice.”中They指代icehousesoricepits，讲解地下冰坑为其降温，衔接冰窖构造相关内容。34．前文“Theseboxesheldlargeblocksoficetokeepfoodcool.”说明木质冰盒依靠冰块保鲜，前文也提到1800年代冰块运送开始普及，空处承接冰块供应相关话题。F项“Icedeliverybusinessesgrewasmorehomesrequiredicetopreservefood.”表示随着更多家庭需要冰块保鲜，送冰行业发展壮大，呼应前文冰块运送普及、冰盒靠冰块制冷的内容。35．前文“Bythe1930s,manypeoplewereusingelectricrefrigeratorstokeepfoodfresh.”点明20世纪30年代电冰箱普及，后文介绍如今冰箱配备滤水器、制冰机甚至智能功能，空处衔接电冰箱的技术升级。G项“Sincethen,growthintechnologyhasledthesemachinestobecomemoreadvanced.”中then指代20世纪30年代，说明此后技术发展让冰箱变得更先进，自然过渡到现代冰箱的多样功能。36．wasbuilt【解析】句意：北京国家体育场，也被叫作鸟巢，是为2008年奥运会建造的。主语TheBeijingNationalStadium和动词build是被动关系；时间2008OlympicGames表示过去，要用一般过去时的被动语态；be动词用was，build的过去分词是built，故填wasbuilt。37．contributions【解析】句意：他对医学做出了许多贡献。空格前“many”后接可数名词复数；contribute是动词，意为“贡献”，其名词形式为contribution，其复数形式为contributions，固定搭配makecontributionsto…意为“对……做出贡献”。38．Courage【解析】句意：勇气帮助我们面对困难。此处需要名词作主语，courage“勇气”，不可数名词，首字母大写。39．societies【解析】句意：不同的社会拥有不同的文化。different意为“不同的”，后面接可数名词复数。society是以“辅音字母+y”结尾的名词，变复数需要把y改为i，再加-es。40．knowledge【解析】句意：我们需要足够的知识来好好学习。句中enough意为“足够的”，后面接名词；know是动词，意为“知道，了解”，它的名词形式是knowledge，表示“知识”，为不可数名词。41．Wise【解析】句意：睿智的建议指引我们前进。wise“睿智的”，形容词作定语修饰名词advice，句首字母大写。42．pioneer【解析】句意：鲁迅是中国的一位文化先驱。不定冠词a后接单数名词，根据汉语提示可知，“先驱”用pioneer表示。43．experiments【解析】句意：他们一起完成日常实验。experiment“实验”，可数名词；此处表泛指，用复数形式experiments。44．research【解析】句意：坚持每天做专业研究。括号中文提示“研究”，professional是形容词，后面接名词。research，含义“研究”，doresearch“做研究”，所以填research。45．create【解析】句意：人才能够不断创造新事物。情态动词can后面接动词原形，create意为“创造”。46．isusedto【解析】原句中“习惯于做某事”是关键词；“习惯于做某事”对应的固定短语为“beusedtodoingsth.”；主语He为第三人称单数，be动词用is。47．madecontributionsto【解析】原句中“作出巨大贡献”是关键词，对应的英语为makegreatcontributionsto。本句描述已经发生过的事件，时态使用一般过去时，make的过去式为made。故填made；contributions；to。48．developmentprogress【解析】原句中“发展”和“进步”是核心关键词。表示“发展”的单词是development，withthedevelopmentof是固定搭配，意为“随着……的发展”；表示“进步”的单词是progress，makegreatprogress是常用固定短语，意为“取得巨大进步”，progress为不可数名词，无需变形。49．ismadeof【解析】原句中“由……制成”是关键词，表示“由……制成（看得见原材料）”的短语是bemadeof。句子陈述事实，时态为一般现在时，主语“Thechair”为单数，be动词用is。50．Inancienttimesdependedon【解析】原句中“古时候”是关键词，表示“古时候”的短语是inancienttimes；“依靠”是关键词，表示“依靠”的短语是dependon。本句为一般过去时，谓语动词要用过去式。注意句首单词首字母要大写。故填In；ancient；times；depended；on。51．attention52．made53．help54．ask55．studied56．students’57．tools58．healthy59．better60．different【导语】本文讲述13岁女孩邱雨陌开发AI学习工具“AIButton”的故事，介绍其功能、开发过程及团队扩展。【解析】51．句意：但我没想到它能吸引这么多人的关注。前文提到“想要一个工具帮助学习”，后文说“吸引很多人”，此处需名词作draw的宾语。所给名词有attention、health、student、tool。drawattention是固定搭配，意为“吸引注意力”；draw不能接health、student或tool表达“吸引”的含义，故排除其他。52．句意：去年她为中学生制作了一款名为AIButton的在线AI学习工具。此处需动词过去式描述过去动作，所给动词有help、study、make、ask，make意为“制作”且能接tool作宾语，根据过去时态需变为made，help/study/ask语义不符。53．句意：我和同学们想要一个学习伙伴来帮助我们记住关键信息。此处需动词原形（不定式表目的），所给词中还剩动词help、study、ask，helpsb.dosth.是固定搭配意为“帮助某人做某事”，study和ask不符合“帮助”的语境。54．句意：当我们有不懂的东西时可以随时求助。此处需动词原形（can后接原形），所给动词还有ask、study，askforhelp是固定搭配意为“寻求帮助”，study不能与forhelp搭配，故排除。55．句意：学生只需将他们已经学过的内容输入AIButton。此处需过去分词与have构成现在完成时，所给动词study意为“学习”且接“内容”作宾语合理，根据完成时需变为studied。56．句意：AI会快速找出重点、提出问题并回答学生们的问题。此处需名词所有格修饰questions，所给名词student需变为复数所有格students’表示“学生们的”，与上文
