-2026年湖南高考(英语)历年真题及答案PartIMultipleChoice(50points)（1）Itwasnotuntilshetookoffherdarkglasses______Irealizedshewasafamousfilmstar.（）AwhenBthatCwhichDwho答案：B解析：本题考查强调句型。强调句的基本结构为：Itis/was+被强调部分+that/who+其他部分。本句强调的是时间状语从句notuntilshetookoffherdarkglasses。在强调句中，如果被强调部分是人，可以用who或that；如果是物、时间、地点等，通常用that。这里强调的是时间状语，故用that。还原原句为：Ididnotrealizeshewasafamousfilmstaruntilshetookoffherdarkglasses.故选B。（2）Themanagerdecidedtogivethejobto______hebelievedhadstrongprofessionalskills.（）AwhomeverBwhoeverCwhateverDwhichever答案：B解析：考查宾语从句中的连接代词。空格处引导介词to的宾语从句，且在从句中作主语（hebelieved是插入语），指代人，故应用whoever。whomever在从句中只能作宾语。（3）____isknowntoall,Chinaisadevelopingcountry.（）AWhatBWhichCAsDThat答案：C解析：本题考查非限制性定语从句。Asisknowntoall是固定搭配，意为“众所周知”，as引导非限制性定语从句，指代后面整个主句的内容，且可置于句首。What不能引导定语从句；Which引导非限制性定语从句通常置于主句之后；That不能引导非限制性定语从句。故选C。（4）Whichwordisanantonymof'artificial'?（）AfakeBnaturalCman-madeDsynthetic答案：B解析：本题考查反义词辨析。artificial意为“人工的，人造的”。A项fake(假的)、C项man-made(人造的)、D项synthetic(合成的)均为近义词；只有B项natural(自然的)是其反义词。故选B。（5）Itisgenerallybelievedthatteachingis______itisascience.（）AanartmuchasBmuchanartasCasanartmuchasDasmuchanartas答案：D解析：考查固定搭配和比较结构。句意为：“人们普遍认为，教学与其说是一门科学，不如说是一门艺术。”此处使用了asmuchAasB的结构，表示“与其说是B，不如说是A”或“A和B一样多”。当名词前有不定冠词时，顺序应为：as+much/many+adj.+a/an+n.+as。因此正确语序是asmuchanartas。（6）Whichofthefollowingwordshasthestressonthefirstsyllable?（）AbelieveBdecideCanswerDpolice答案：C解析：本题考查单词重音。A项believe/bɪˈliːv/，B项decide/dɪˈsaɪd/，D项police/pəˈliːs/的重音均在第二个音节。只有C项answer/ˈɑːnsə(r)/的重音在第一个音节。故选C。（7）Didyouenjoytheparty?Yes.We______wellbyourhosts.（）AweretreatedBwouldbetreatedCtreatedDhadtreated答案：A解析：本题考查时态和语态。根据问句"Didyouenjoy..."可知动作发生在过去，且主语We与treat之间是被动关系（被主人招待），因此应用一般过去时的被动语态weretreated。故选A。（8）Thescientist______theexperimentforthreehoursbeforehefinallygotthedesiredresult.（）AhadconductedBhasconductedCwasconductingDconducted答案：A解析：本题考查时态。句意：这位科学家在最终得到理想结果之前，已经进行了三个小时的实验。根据时间状语'beforehefinallygot...'可知，'conducttheexperiment'这一动作发生在'got'之前，即“过去的过去”，因此应使用过去完成时haddone。故选A。（9）____theheavyrain,theystillwentoutforawalk.（）AAlthoughBDespiteCBecauseDSince答案：B解析：本题考查让步状语。空格后是名词短语theheavyrain，而非句子。Although和Because,Since是连词，后接句子；Despite是介词，后接名词或动名词，表示“尽管”。故选B。（10）I'mafraidIcan'tfinishtheworkontime.Don'tworry.You______havedoneitbetterifyouhadfollowedmyadvice.（）AmustBcouldCwouldDshould答案：C解析：考查虚拟语气。根据后半句ifyouhadfollowedmyadvice（如果你听了我的建议）可知，这是对过去情况的虚拟假设（事实是没听建议）。主句应使用would/could/might/should+havedone结构。结合语境“别担心，你本可以做得更好”，表示一种对过去可能性的推测或结果，wouldhavedone最为常用且符合逻辑，表示“本来会……”。虽然could也有“本来能够”的意思，但在表示“如果不那样做，结果就会不同”的确定性推论时，would更贴切；若强调能力则用could。在此类高考题中，通常考察would表示与过去事实相反的结果。（11）Thescientist,alongwithhisassistants,______workingonthenewprojectlastnight.（）AwasBwereCisDare答案：A解析：本题考查主谓一致。当主语后跟有with,togetherwith,alongwith,aswellas等短语时，谓语动词的单复数形式由前面的主语决定。本句主语是Thescientist（单数），且时间状语为lastnight（过去时），故谓语动词应用单数过去式was。（12）The______ofthemountainwascoveredwithsnow,makingitlookmajestic.（）ApeakBvalleyCslopeDbase答案：A解析：本题考查名词辨析。句意为“山顶覆盖着雪，使其看起来雄伟壮观”。peak意为“山顶，顶峰”，符合语境。valley山谷，slope斜坡，base底部，均不符合“覆盖雪且显得雄伟”的典型特征描述（通常指最高处）。故选A。（13）Thescientist______thenewtheorywithgreatenthusiasm,believingitwouldrevolutionizethefield.（）ArejectedBembracedCignoredDcriticized答案：B解析：句意：这位科学家热情地接受/拥抱了新理论，相信它将彻底改变这一领域。根据后半句“believingitwouldrevolutionizethefield”（相信它将彻底改变这一领域）可知，科学家对该理论持积极态度。A项reject（拒绝）、C项ignore（忽视）、D项criticize（批评）均不符合语境。B项embrace在此处意为“欣然接受、采纳”，符合语境。（14）Itisgenerallybelievedthatteachingis______itisascience.（）AanartmuchasBmuchanartasCasanartmuchasDasmuchanartas答案：D解析：考查同级比较结构。as...as...结构中，第一个as是副词，第二个as是连词。当形容词修饰单数可数名词时，语序为：as+adj.+a/an+n.+as。teachingisasmuchanartasitisascience意为“教学既是一门科学，也是一门艺术”。故选D。（15）Thescientist______theexperimentcarefullybeforedrawinganyconclusions.（）AobservedBhasobservedChadobservedDwasobserving答案：C解析：本题考查时态。句意：这位科学家在得出任何结论之前，已经仔细观察了实验。动作“观察”发生在“得出结论”这一过去动作之前，即“过去的过去”，因此应使用过去完成时（haddone）。故选C。（16）Itisgenerallybelievedthatteachingis______itisascience.（）AanartmuchasBmuchanartasCasanartmuchasDasmuchanartas答案：D解析：本题考查同级比较结构。'as+adj./adv.+a/an+n.+as'是固定搭配，意为“和……一样……”。句中修饰的是名词art，形容词much放在冠词an之前，即'asmuchanartas'。句意：人们普遍认为，教学既是一门科学，也是一门艺术。故选D。（17）Whichofthefollowingwordshasadifferentsoundfortheunderlinedpart?（）Ac<u>a</u>tBb<u>a</u>gCm<u>a</u>pDn<u>a</u>me答案：D解析：本题考查元音字母发音。A项cat/kæt/，B项bag/bæg/，C项map/mæp/，划线部分均发/æ/音；D项name/neɪm/，划线部分发/eɪ/音。故选D。（18）Thescientist,alongwithhisassistants,______workingontheprojectdayandnighttomeetthedeadline.（）AisBareCwasDwere答案：A解析：本题考查主谓一致。主语是'Thescientist'，'alongwithhisassistants'是插入语，不影响谓语动词的单复数。因此谓语动词应与单数主语'Thescientist'保持一致。根据语境'working...tomeetthedeadline'暗示动作正在进行或一般性事实，且选项中有is/are/was/were。通常此类题目若无明确过去时间状语，且强调当前状态，用一般现在时或现在进行时。这里'isworking'构成现在进行时，符合语境。若选was，需有明确过去时间背景。在没有特定过去时间背景下，一般现在时或现在进行时更常见。对比选项，A(is)和C(was)都是单数。考虑到'dayandnight'常与进行时连用表示持续努力，且高考题中若无过去标志，优先选现在时态。故排除B、D。在A和C中，若无上下文暗示过去，默认现在时。故选A。（19）Notuntilhearrivedatthestation____thathehadlefthisticketathome.（）AherealizedBdidherealizeChedidrealizeDrealizedhe答案：B解析：本题考查倒装句。当'Notuntil'位于句首时，主句需要使用部分倒装语序，即将助动词提到主语之前。本句时态为过去时，故借助于did，构成'didherealize'。（20）Itisgenerallybelievedthatteachingis______itisascience.（）AanartmuchasBmuchanartasCasanartmuchasDasmuchanartas答案：D解析：本题考查同级比较结构。固定搭配为"as+adj./adv.+a/an+n.+as"。句意为：人们普遍认为，教学既是一门科学，也是一门艺术。其中"asmuchanartas"符合该结构，故选D。（21）Iwouldratheryou____methetruthyesterday.（）AtellBtoldChavetoldDhadtold答案：D解析：本题考查wouldrather后接从句的虚拟语气。当表示与过去事实相反的愿望时，从句谓语动词需用过去完成时(haddone)。句中有yesterday，说明是对过去的虚拟，故填hadtold。（22）Thenewpolicyaimsto______thegapbetweentherichandthepoor.（）AbroadenBnarrowCwidenDdeepen答案：B解析：句意：新政策旨在缩小贫富差距。broaden意为“拓宽”；narrow意为“使变窄，缩小”；widen意为“加宽”；deepen意为“加深”。根据语境，政策通常是为了缩小差距，故选B。（23）Theboysatinthecorner,____bythenoiseoutside.（）AfrighteningBfrightenedCtofrightenDhavingfrightened答案：B解析：本题考查过去分词作状语或定语。逻辑主语Theboy与frighten之间是被动关系（男孩被吓到），因此应用过去分词frightened表示状态。Frightening意为“令人害怕的”，通常修饰物；tofrighten表目的或将来，不符合语境。（24）____makesthebooksopopularisitsuniquestyle.（）AThatBWhichCWhatDWho答案：C解析：本题考查主语从句引导词。分析句子结构，____makesthebooksopopular是整个句子的主语部分。在该从句中，缺少主语，指代“事物”，故用What。That在主语从句中不充当成分，Which表示选择，Who指代人。句意为：让这本书如此受欢迎的是它独特的风格。故选C。（25）Notonly______interestedinfootballbutalsobeginningtoshowaninterestinit.（）Atheteacherhimselfis;allhisstudentsareBtheteacherhimselfis;areallhisstudentsCistheteacherhimself;areallhisstudentsDistheteacherhimself;allhisstudentsare答案：D解析：本题考查倒装句和主谓一致。notonly...butalso...连接两个分句时，若notonly位于句首，其后的分句需部分倒装，而butalso后的分句不倒装。因此第一空应为istheteacherhimself；第二空主语为allhisstudents，谓语动词用复数are，且无需倒装。PartIIGap-filling(14points)（1）Completethesentencewiththeappropriatepreposition:"Shehasbeeninterested______classicalmusicsinceshewasachild."答案：in解析：本题考查固定搭配。beinterestedin是固定短语，意为“对……感兴趣”。故填in。（2）Anyone____breaksthelawwillbepunished.答案：who解析：本题考查定语从句的关系代词。先行词是Anyone（指人），且在从句中作主语（breaks的主语），故只能用who，不能用whom或which。注意：当先行词是不定代词（如anyone,everyone,nothing等）时，关系代词通常只用who或that，此处填who最为标准。（3）Itisstronglyrecommendedthateveryone______(wear)aseatbeltwhiledriving.答案：(should)wear解析：考查虚拟语气。在'Itisrecommended/suggested/orderedthat...'句型中，that引导的主语从句谓语动词需用虚拟语气，即'(should)+动词原形'。'should'可以省略，故填'wear'或'shouldwear'。（4）Thenumberofstudentswho______(be)willingtotakepartintheactivityhasincreasedgreatly.答案：are解析：考查主谓一致。定语从句中的谓语动词应与先行词保持一致，此处的先行词是students（复数），因此从句谓语用are。注意主句的主语是Thenumber（单数），所以主句谓语用了has。（5）Thenewpolicyaimstoreducecarbonemissionsby30%withinfiveyears.Manyexpertsbelievethistargetisambitiousbut1______ifstrictmeasuresaretaken.答案：achievable解析：句意为“许多专家认为这个目标虽然雄心勃勃，但如果采取严格措施，是______的”。achieve的形容词形式achievable意为“可实现的”，符合语境。（6）Lastsummer,IvisitedasmallvillageinYunnan.Thescenerywasbreathtaking,withgreenmountainsandclearrivers.Thelocalswereveryfriendlyandwelcomeduswarmly.Westayedinatraditionalwoodenhouse,which1______(build)overahundredyearsago.Everymorning,wewokeuptothesoundofbirdssinging.Itwasapeacefulexperiencethatallowedmetoescapefromthebusycitylife.Irealizedthatsometimes,slowingdownisthebestwaytoappreciatethebeautyofnature.Thistripnotonlyrelaxedmybodybutalsorefreshedmymind.Ihopetoreturnthereagaininthefuture.答案：wasbuilt解析：1.考查时态和语态。句子主语which指代先行词'atraditionalwoodenhouse'，与动词build之间是被动关系。根据时间状语'overahundredyearsago'，可知动作发生在过去，故使用一般过去时的被动语态wasbuilt。（7）Thenewpolicywillhaveasignificantimpact______thelocaleconomy.答案：on解析：本题考查介词搭配。haveanimpacton...是固定搭配，意为“对……产生影响”。故填on。（8）Thescientistdevotedallhislifeto______(research)thecausesofthedisease.答案：researching解析：考查固定搭配与非谓语动词。devote...to...是固定短语，意为“致力于……”，其中to是介词，后面接名词或动名词（V-ing）。因此research需变为researching。（9）Thenewpolicyaimstoreducecarbonemissionsby30%withinthenextdecade,whichisconsideredasignificantsteptowards1______(achieve)carbonneutrality.答案：achieving解析：本题考查非谓语动词。介词towards后面接动词时，必须使用动名词形式（v-ing）。achieve的动名词形式为achieving。故填achieving。（10）Itiswidelybelievedthatregularexercisecontributestobetterhealth.Pleasefillintheblankwiththecorrectformofthewordgiven:Manypeoplearebecomingincreasinglyawareofthe1______(important)ofabalanceddiet.答案：importance解析：本题考查词性转换。空格前有定冠词'the'和介词'of'，说明此处需要填入名词形式。'important'是形容词，其名词形式为'importance'。故填importance。（11）Shehasbeenworkinginthiscompanyfortenyears,sosheisquitefamiliar1______thebusinessoperations.答案：with解析：本题考查固定搭配。befamiliarwithsth.意为“熟悉某事”；befamiliartosb.意为“某事对某人来说是熟悉的”。此处主语是人，宾语是事物，故用with。（12）Intoday'sfast-pacedworld,stressiscommonamongstudents.Todealwithit,expertssuggesttakingregularbreaksanddoingexercise.Theseactivitieshelpreduceanxietyandimprove6______.Ahealthybodyleadstoahealthymind.答案：concentration解析：6.锻炼和休息能减少焦虑并提高“注意力”或“专注力”，concentration符合上下文关于学习效率的讨论。（13）Thenewpolicyaimstoreducecarbonemissionsby30%withinthenextdecade,whichisasignificantsteptowardsenvironmental1______(protect).答案：protection解析：本题考查词性转换。空格前为形容词environmental，修饰名词，因此需要将动词protect转换为名词形式protection。environmentalprotection意为“环境保护”。故填protection。（14）Itisgenerallybelievedthatteachingisasmuchanartasitisascience.Thekeytosuccessliesin1______(balance)thesetwoaspectseffectively.答案：balancing解析：本题考查非谓语动词。liein意为“在于”，in是介词，后面接动名词作宾语。balance的动名词形式为balancing。故填balancing。PartIIICloze(30points)（1）WhenIwasyoung,mygrandfatherusedtotellmestoriesabouthischildhood.Hegrewupinasmallvillagewherelifewassimplebuthard.Oneday,hefoundawoundedbirdintheforest.Insteadofignoringit,hedecidedtotakecareofi
