ull且answer为数组,这符合语法填空或多空填空的逻辑。若必须模拟传统完形填空(有选项),则应使用单选格式拆分,但规范要求完形填空使用单题格式且options为null。因此,这里按“多空填空/语法填空”逻辑处理文本中的空缺。修正:根据用户指令“完形填空...options为null...answer必须为数组”,上述题目设计为短文填空形式。1.根据前文"goesrunning",此处指跑步这项运动,或者原文若有空位。假设原文是:Heloves1______.->running.2.地点状语,school2______.->playground.3.谓语动词,team3______.->wins.4.情感形容词,felt4______.->sad.5.副词比较级,practiced5______.->harder.(4)Lifeisfullofchallenges.Whenwefacedifficulties,weshouldnotgiveupeasily.Instead,weshouldtryourbesttoovercomethem.Lastterm,Ihadahardtimewithmymath.NomatterhowhardItried,Ialwaysgotlowgrades.Ifeltvery1______andwantedtogiveup.Myteachernoticedmyproblemandtalkedtome.Shetoldmethatfailureisthemotherofsuccess.Sheencouragedmetokeeptryingandhelpedmefindtherightwaytostudy.Withherhelp,Imadegreatprogress.Inthefinalexam,IgotanA.IwassohappythatIcouldn'tbelieveit.Fromthisexperience,Ilearnedthatnothingisimpossibleifweputourheartintoit.Weshouldbebraveenoughtofaceany2______.Aslongaswedon'tgiveup,wewillsucceedintheend.So,dearfriends,whenyoumeetdifficulties,pleaseremember:keepgoing,andyouwillseetherainbowaftertherain.答案:1.sad2.challenge解析:1.根据上下文,作者数学成绩一直很低,感到想放弃,情绪应该是低落的。sad(悲伤的)符合语境。2.根据前文"Lifeisfullofchallenges"以及后文"whenyoumeetdifficulties",此处指我们要勇敢面对任何挑战。challenge(挑战)符合语境,且与前文呼应。(5)LastSunday,Iwenttotheparkwithmyfriends.Wehadagreattimethere.Whenwearrived,thesunwasshiningbrightly.Wedecidedtohaveapicnicunderabigtree.Whilewewereeating,alittledogcametous.Itlookedhungry.MyfriendTomgaveitsomebread.Thedogateit1______andwaggeditstail.Afterlunch,weplayedgamestogether.Weranandlaughedhappily.Suddenly,itstartedtorain.Wedidn'tbringumbrellas,sowerantoanearbyshelter.Althoughwegotwet,westillfelt2______.Itwasanunforgettableday.Onourwayhome,wetalkedaboutthefunnythingsthathappened.Ithinkfriendshipisoneofthemostimportantthingsinlife.Itmakesourlivesmorecolorfulandmeaningful.Ihopewecanalwaysstay3______likethis.答案:1.quickly2.happy3.friends解析:1.根据前文"Itlookedhungry"和后文"waggeditstail",狗吃到面包后应该是“快速地”吃,故填quickly。2.根据前文"Althoughwegotwet"(虽然我们要淋湿了)和转折关系,以及后文"unforgettableday",说明心情依然是“快乐的”,故填happy。3.根据全文主题关于友谊,以及"stay...likethis",希望我们能一直保持像这样的“朋友”关系,或者保持这种状态。结合语境,stayfriends是常见搭配,意为“保持朋友关系”。四、​写作(2题)(1)健康的生活方式对中学生非常重要。请以'HowtoKeepHealthy'为题,写一篇短文,谈谈你对保持健康的看法和建议。要点提示:1.均衡饮食(多吃蔬菜水果,少吃垃圾食品);2.适量运动(每天锻炼,如跑步、打球等);3.充足睡眠(早睡早起,不熬夜);4.保持好心情。要求:1.词数80~100左右;2.包含所有要点,可适当发挥;3.文中不得出现真实姓名和学校名称。HowtoKeepHealthyHealthisveryimportantforeveryone.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________答案:(略)解析:本题考查命题作文。写作时需围绕'如何保持健康'展开,覆盖饮食、运动、睡眠和心情四个要点。建议使用first,second,third,finally等连接词使文章条理清晰。时态以一般现在时为主。范文结构完整,要点齐全,语言规范。(2)假设你是李华,你的美国朋友Mike想学习中文。请你给他写一封邮件,推荐一些学习方法。内容要点:1.多看中文电影和听中文歌;2.找中国朋友练习口语;3.每天坚持记十个单词;4.不要怕犯错,大胆开口说;5.祝他学习进步。注意:1.词数60-80左右;2.邮件格式已给出,不计入总词数。DearMike,I'mgladtoknowyouwanttolearnChinese.Herearesometipsforyou.____Yours,LiHua答案:(略)解析:写作指导:1.体裁:电子邮件(建议类)。2.时态:提出建议主要使用情态动词(can/should)或祈使句。3.要点覆盖:-方法1:watchmovies,listentosongs。-方法2:findfriends,practicespeaking。-方法3:rememberwordseveryday。-态度:Don'tbeafraidofmistakes,speakout。-祝福:learnwellsoon。4.连接词:使用First,Second,Third使条理清晰。5.范文分析:范文结构严谨,建议具体可行,语气鼓励性强,符合书信规范。五、​阅读理解(3题)阅读理解1Manypeoplethinkthatrobotswilltakeovertheworldinthefuture.However,scientistssaythatrobotsaredesignedtohelphumans,nottoreplacethem.Robotscandodangerousjobs,suchasexploringdeepoceansorworkinginradioactiveareas.Theycanalsodoboringandrepetitivetasks,likeassemblingcarsinfactories.Thisallowshumanstofocusonmorecreativeandcomplexwork.Inhospitals,robotsareusedtoassistdoctorsinsurgeries.Theycanperformoperationswithhighprecision,whichreducestheriskoferrors.Inhomes,robotvacuumscleanfloors,savingpeopletimeandeffort.Despitethesebenefits,somepeopleworryaboutjoblosses.Itistruethatsomejobsmaydisappear,butnewjobswillbecreated.Forexample,peoplewillbeneededtodesign,program,andrepairrobots.Therefore,insteadoffearingrobots,weshouldlearnhowtoworkwiththem.Educationplaysakeyroleinthisprocess.Schoolsshouldteachstudentsskillsthatrobotscannoteasilyreplicate,suchascriticalthinking,creativity,andemotionalintelligence.(1-1)Whatisthemainpurposeofrobotsaccordingtoscientists?()A.ToreplacehumanscompletelyB.TohelphumansC.TotakeovertheworldD.Tomakemoneyforcompanies(1-2)WhichofthefollowingisNOTmentionedasajobrobotscando?()A.ExploringdeepoceansB.AssemblingcarsC.TeachingstudentsinclassroomsD.Assistinginsurgeries(1-3)Whydosomepeopleworryaboutrobots?()A.RobotsaretooexpensiveB.RobotsmightcausejoblossesC.RobotsarenotsmartenoughD.Robotsconsumetoomuchenergy(1-4)Whatskillsshouldschoolsteachstudentsaccordingtothepassage?()A.HowtorepaircarsB.Criticalthinking,creativity,andemotionalintelligenceC.HowtoassemblerobotsD.Basiccomputerskillsonly答案:1-1.B1-2.C1-3.B1-4.B解析:1.根据第一段'scientistssaythatrobotsaredesignedtohelphumans'可知选B。2.文中提到了探索深海、组装汽车、辅助手术,未提到在课堂上教学生,故选C。3.根据第三段'somepeopleworryaboutjoblosses'可知选B。4.根据最后一句'Schools
