参考答案及试题解析

1.B2.B3.C4.A5.B6.A7.C8.D9.D10.A11.B12.B

13.C14.C15.D

【导语】本文介绍了条形码的发明历程。从店主遇到记录难题，到学生发明系统，历经改进与专利申请，

最终条形码在全球商店普及，方便人们获取产品信息。

【解析】1.句意：一个小食品店的老板发现记录产品信息很难。

根樨后文“asked...tosolve”可知是需要解决的难题，因此表示困底（difficult）。easy容易的，interesling有趣

的，boring无聊的,均不符合语境。

2.句意：1948年，他要求德雷塞尔理工学院解决这个问题。

根据后文“theproblemswouldhavetobesoNed”可知此处指问题（problem）,plan计划，project项目，doubt

怀疑，均与solve搭配不当或语意不符。

3.句意：研究生伯纳德・西尔弗对此很感兴趣。

根据后文“toworkonit”,他开始从事这项工作，可知是感兴趣（imerested）。bored无聊的，tired累的，surprised

惊讶的，无法引出后文的行动。

4.句意：他和另一名学生开始从事这件事。

根据前文感兴趣，可知是开始做（started）。continued继续，喑示之前做过，而此处是事情的开端：refused

拒绝，failed失败，与后文发明成功矛盾。

5.句意：很快，他们发明了第一个工作系统。

根据后文“Thesystemdidwork”可知此处指系统（system）。way方式,part部分，situation情况,与后文指

代不一致。

6.句意：这套系统起初的确起作用。

根据后文“FinaHy...solved”可知此处表示刚开始（atfirst）。forexample例如，ontime按时，inperson亲自，

均不符合时间逻辑。

7.句意：但它很贵，有时系统工作不好。

根据前文“didwork”可知并非完全无效，而是不稳定，sometimes“有时”符合语境。hardly几乎不，seldom

很少，never从不，与前文矛盾。

8.句意：如果这项发明要在商店里受欢迎，这些问题必须得到解决。

根据后文“thesystemwasstillnotpopular”，可知目标是受欢迎（popular）。lively活泼的，cheap便宜的，direct

直接的，不符合商业普及语境。

9.句意：最后，伍德兰成功解决了它们。

此处指代前文复数名词“problems”,用them。it它，单数；him他,her她,人称不符。

10.句意：在条形码系统上的专利权在1949年被Silver和Woodland所申请。

根据"Thepatent...in1949,butthepatentwasnotgivenuntil”,可知此处指申请专利,askfor意为“请求/申请”,

固定搭配。offered提供,made制作，divided分开，无此搭配或语义不通。

11.句意：尽管授予了专利，系统仍在商店老板间不受欢迎。

根据"thispatentwasgiven”（授予专利）与"thesystemwasstillnotpopular'（系统仍不受欢迎）,前后句表示

让步关系，用Although“尽管"。Unless除非，If如果，Since自从，逻辑关系不符。

12.句意：尽管授予了专利，系统仍在商店老板间不受欢迎。

店主“storeowners”是群体（三者以上），用amongobetween两者之间；during在...期间，in在....里面，

语义不符。

13.句意：在1970年，一个名口ILogicon的公司发明了通用杂货产品识别码。

根据语境是创造新代码,用发明（invented）（»found找到，mentioned提到,remained保持,均不符合创造

新事物的语境。

14.句意：Trony的Marsh超市是第一家建立这种条形码读取系统的商店。

根据宾语“thisbarcodereadingsystem”,搭配setup“建立”，表示“建立...系统"。giveup放弃,putup举

起，cleanup清理,与system搭配不当。

15.句意：现在世界各地商店都在使用它。

根据后文“Ithelpsustoeasilyknowaboutsomeinformationofproducts?5,帮助获取信息,可知是被使用（used）。

repaired修理，iried尝试，learned学习，不符合普及后的状态。

16.B17.C18.D19.C20.A

【导语】木文主要讲述了印度少年Aarrav为都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）,strugglingtofeed

himself.Foodkeptfallingoutofhismouth,makinghimlooklikeamess”和第三段“Aarravwantedhisuncleto

beabletoeatbyhimsel「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•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•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.Ihadtobuysomefrom

abroad”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,peopledependedon

heavybambooslips,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“Betbreitscreation（纸发明前）”"WesternHanDynasty（西汉）”"Eastern

HanDynasty（东汉）,,t4laterspreadtoothercountries（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口常使用。

24.由第三段“Thischangemadep叩ercheaperandmorepractical”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,andfinallytoallpartsofihe

world”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，［t|t4Eventoday,paperremainsan

importantpartofourdailylife”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】木文讲述了一个青少年团队在4g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“plannedanappthatwouldidentifyeveryditYiculty...Sixhourslater,theyhada

beautil'ulscreenandalmoslnothingIhalworked”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;teacherscreatedthelabelwhenthey

wrotethequestion”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

建诃题的老师”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。

【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“Thefirstelectricrefrigeratorwasmadein19解”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“Before

then,peoplefoundotherwaystostoretheirfood.^^中ihen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。
