讀】本文是一篇說明文。文章主要介紹了蜜蜂不僅是蜂蜜制造者,更是至關(guān)重要的傳粉者,對于維護生態(tài)系統(tǒng)平衡、豐富農(nóng)作物多樣性起著不可或缺的作用,同時指出蜜蜂面臨的生存挑戰(zhàn)及保護蜜蜂的緊迫性。5.Whyarepollinatorsimportant?A.Theyhelpthebeesfertilize.B.Theykeepthecropsdiverse.C.Theysupportthebeestomakehoney.D.Theyprotectinsectssuchaswasps.答案B解析細節(jié)理解題。根據(jù)第一段的“Beesaremorethanjusthoney-makers.Theyareessentialpollinatorsthathelpmaintainthebalanceofourecosystemsandthediversityofourcrops.”可知,傳粉昆蟲很重要是因為它們在維持生態(tài)系統(tǒng)平衡和農(nóng)作物多樣性方面至關(guān)重要。6.Whatisthesecondparagraphmainlyabout?A.Howpollinationworks.B.Howtheflowersattractbees.C.Howthebeesreproduce.D.Howtheplantsproducefruits.答案A解析主旨大意題。根據(jù)第二段內(nèi)容可知,第二段主要介紹了蜜蜂通過取食花蜜和花粉進行傳粉,從而幫助植物受精和繁殖的過程,即“傳粉是如何運作的”。7.Whatdoestheunderlinedword“This”inparagraph5probablyreferto?A.Climatechange.B.Pesticideuse.C.Pollinators’survivalcrisis.D.Bees’habitatloss.答案C解析詞句猜測題。根據(jù)第五段的“TheFAOestimatesthat16.5%ofvertebratepollinatorsand40%ofinvertebratepollinators,suchasbees,arefacingextinction.”可知,蜜蜂和其他傳粉者面臨滅絕的危機,“這種危機”可能導(dǎo)致嚴重的后果,因此,“This”指代的是“傳粉者生存危機”。8.Whichwouldbethebesttitleforthetext?A.Aduty:ProtectBees’HabitatB.AMeans:ObserveBees’BehaviourC.Bees:MaintainersoftheEcosystemD.Bees:ConsumersattheTopoftheFoodChain答案C解析主旨大意題。通讀全文,尤其根據(jù)第一段以及倒數(shù)第二段內(nèi)容可知,文章主要圍繞蜜蜂作為生態(tài)系統(tǒng)維護者的核心角色展開,論述了其傳粉功能對農(nóng)業(yè)生產(chǎn)、生物多樣性和環(huán)境穩(wěn)定性的重大意義,同時指出蜜蜂面臨的生存挑戰(zhàn)及其保護的緊迫性。所以“蜜蜂:生態(tài)系統(tǒng)維護者”適合作本文的標題。Passage3(2024四川成都二模)主題:保護個人隱私詞數(shù):303難度:★★★☆☆There’sanenormousamountofpersonalhealthinformationpeoplenowfeedortapintodigitalmonitors,healthapps,searchenginesandotheronlinetools.Ifthesameinformationwereprovidedinyourdoctor’soffice,yourprivacywouldbesafeguarded.Butthat’snothowthedigitizedhealthworldworks.Instead,wehaveanecosystemofabuseinwhichhealthtechnologycompaniesoperatelargelyoutsidethelawthatrequiresdoctorsandothermedicalpersonnel,hospitalsandinsurerstoprotectanindividual’shealthinformation.Thatmeanstechnologycompaniescan—anddo—digyourdigitaldataforcluesaboutyourhealthstatus,accessinginformationlikeprescriptionsyouhavepurchasedandotherhealthservicesyoumighthavesought,andpotentiallylinkthisinformationtoyourname,address,emailaddressandotherpersonallyidentifyinginformation.ThedatacanthenbeusedbyplatformsincludingMetaandGoogletohelpadvertiserstargetpromotionsorothercommunicationstoyou.It’sagapingholeinhealthprivacyprotectionsthatcomesfromtheprivacylaw,whichprotectsinteractionsbetweenpatients,medicalprofessionalsandinsurersbutdoesnot,inmostcases,protectpatienthealthdatathatisrecordedonnewtechnologies.Closingthepatientprivacygapcan-andshould-beapriorityforlawmakers.Theconsequencesofdigitalexposureforthoseseekingreproductiveserviceshavedrawnsignificantconcernandattention.Theseworriesarereasonable.Butreproductivecareisonlyoneareaofhealthserviceswhereprivatepatientinformationisdigitallydisclosed.Therefore,lawmakersmusttakeactiontoprotecttheprivacyofpeoplewhoarenowonlineforallmannersofpersonal,professionalandotherreasons.Untilthen,anarrowlytargetedapproachthatprotectshealthprivacymaybepoliticallyeasiertocomeintoeffect.Theexplosionofdigitalhealthtechnologyandthedramaticincreaseinitsuseinthepastfewyearsrequireitgreatly.【語篇導(dǎo)讀】本文是一篇議論文。文章主要圍繞數(shù)字化健康世界中個人隱私保護的問題展開論述,分析了當前健康技術(shù)公司在處理個人健康信息時存在的法律漏洞和濫用現(xiàn)象,并強調(diào)了立法者需要采取行動來保護個人隱私的重要性。9.Whatcanwelearnaboutthepresentsituationofthedigitizedhealthworld?A.Personalhealthdataisusedforotherpurposes.B.Personalhealthinformationisdifficulttoidentify.C.Targetedpromotionsareusedtoimprovepeople’shealth.D.Medicalpersonnelprotectthepersonalhealthinformationwell.答案A解析細節(jié)理解題。根據(jù)文章第二段和第三段內(nèi)容可知,現(xiàn)在我們的個人健康信息沒有得到應(yīng)有的保護,這些數(shù)據(jù)反而被包括Meta和谷歌在內(nèi)的平臺使用,以幫助廣告商向你定向促銷或其他通信。10.What’stheauthor’sattitudetowardsthepresentprivacylaw?A.Approving. B.Critical.C.Cautious. D.Ambiguous.答案B解析推理判斷題。根據(jù)文章第四段內(nèi)容可知,作者認為現(xiàn)行的隱私法存在巨大漏洞。由此推知,他對現(xiàn)行隱私法是持批評態(tài)度的。11.Whatdoestheunderlinedword“it”inparagraph6referto?A.Thespreadofhealthservice.B.People’sprivacy.C.Anarrowlytargetedapproach.D.Theexplosionofdigitaltechnology.答案C解析詞句猜測題。根據(jù)畫線單詞上一句“Untilthen,anarrowlytargetedapproachthatprotectshealthprivacymaybepoliticallyeasiertocomeintoeffect.”以及畫線單詞所在句“Theexplosionofdigitalhealthtechnologyandthedramaticincreaseinitsuseinthepastfewyearsrequireitgreatly.”可推測,畫線詞it指的是上文提到的“targetedapproach”。12.Whatisthepurposeofthetext?A.Toadvocateimprovementintheprivacylaw.B.Toreportcasesofillegalinformationexposure.C.Toexplainhowthedigitizedhealthworldworks.D.Tointroduceadebateontheeffectoftechnology.答案A解析推理判斷題。根據(jù)文章最后一段以及全文內(nèi)容可知,文章主要討論了數(shù)字化健康世界中個人隱私保護的問題,特別指出了當前隱私法存在的漏洞以及健康技術(shù)公司如何濫用個人健康信息。作者強調(diào)了這一問題的嚴重性,并呼吁立法者采取行動來彌補這一漏洞,保護個人隱私。由此推知,文章的目的是倡導(dǎo)改進隱私法,以確保個人健康信息得到妥善保護。考點分類練(十)主旨大意題(1)Passage1(2024福建泉州三模)主題:改造舊飛機詞數(shù):305難度:★★★☆☆BruceCampbell,aretiredelectricalengineer,wantedtochangethebehaviorofmankindbyshowinghowwecanrecycleoldthingsintonew-andpractical-andlivableones.Forabout$220,000,hepurchasedaGreekairliner—aBoeing727-400—thatloggedabout40,000flightsinitspeak.BeforeCampbellgothishandsonhisBoeing727andtransformeditintotheairplanehomehelivesin,thisaircraftsawregularuseasittransportedallkindsofpeopletoallsortsofdestinations.Afterthesuccessfultransform,hehostedabigDJdancepartywithacoupleoffriends.Theparty,calledTurbulence:ADancePartyata727intheWoods,happenedrightonthewing!Guestswhoattendedthepartyalsogottheopportunitytotakealookattheairplanehome.Overall,theygottheattentionof14,000Metauserswhowereinterestedinwhatsoundedlikeanincredibleparty.Thistalentedengineergotanotherairlinerandstartedonhissecondairplanehomeduringthebeginningof2018ontheKyushuIslandcoastbecausehewantedittoserveasasafeplaceforthelocalcommunityaswell.PartofBruceCampbell’svisionwastomakeanairlinerthatdoubledasalifeboatincasetsunami(海嘯)threatswereissued.Hewantedthegeneralpublictofindoutthatplanesarecapableofsurvivinghundredsofyearsandthecruelestweatherconditionsthankstoitssealedpressuretechnology.Campbelladoredtheexcitementthathereceivedwhenherecycledairplanesandhopedthatpeoplewouldseriouslyconsideritaftertheygotthechancetoseehishomeduringtoursandevents.Hehaspostedonhiswebsitethatitishisgoalto“inspirearenaissance(復(fù)興)ofthoughtabouthowtoemploythisremarkableresource”.【語篇導(dǎo)讀】本文是一篇記敘文。文章主要介紹了一位退休的電氣工程師BruceCampbell把舊飛機改造成家的故事。1.WhatdrewwidepublicattentiontoCampbell’sfirsttransformedplane?A.Itshighresidentialcomfortlevel.B.Itsremarkabletransportingcapacity.C.Theincrediblyhightransformationcost.D.TheMetapostofapartyheldonit.答案D解析細節(jié)理解題。根據(jù)第三段內(nèi)容可知,Meta上舉辦派對的帖子吸引了公眾對Campbell第一架改裝飛機的廣泛關(guān)注,故選D項。2.WhatdidCampbellthinkthesecondplanecouldserveas?A.Atsunamiwarningcenter.B.Ameetingplaceforlocalcommunity.C.Atemporaryshelterindisasters.D.Anengineeringworkshop.答案C解析細節(jié)理解題。根據(jù)第四段中“Thistalentedengineergotanotherairlinerandstartedonhissecondairplanehome...incasetsunamithreatswereissued.”可知,Campbell認為第二架飛機可以用作災(zāi)難中的臨時避難所,故選C項。3.WhydidCampbelltransformtheplanes?A.Todirectattentiontohousingproblems.B.Tosatisfyhisscientificcuriosity.C.Toadvocateagreenerlifestyle.D.Tocallforparticipationinrecycling.答案D解析細節(jié)理解題。根據(jù)第一段和最后一段內(nèi)容可知,Campbell改造飛機是為了呼吁市民參與循環(huán)再造。4.Whatisthetextmainlyabout?A.Aformerengineerturningretiredplanesintohome.B.Recenttrendsofrenaissance-themeddecoration.C.Atalentedhomedesignerreceivingonlinefame.D.Diverseapproachesforsustainableliving.答案A解析主旨大意題。根據(jù)全文內(nèi)容,結(jié)合第一段“BruceCampbell,aretiredelectricalengineer,wantedtochangethebehaviorofmankindbyshowinghowwecanrecycleoldthingsintonew-andpractical-andlivableones.”可知,文章主要介紹了一位退休的電氣工程師BruceCampbell把舊飛機改造成家的故事,A項“一位前工程師把退役的飛機變成了家”能夠總結(jié)文章大意。Passage2(2024浙江紹興二模)主題:棄用草書詞數(shù):336難度:★★★☆☆I(lǐng)havealwaysbeenproudofmyhandwriting,askillIwastaughtingradeschool.TheteacherwasteachingusthePalmerPenmanshipMethod,drillingintoustheimportanceofformingbigflowinglineswhenwewroteg’sands’saswellasbeautifulf’sthatinmymindwerelikefairytaleprincesseswearingfancyhatswhileextendingtheirrightfoot.Wewerestrictlyprohibitedfromusingblocklettersonourhomework,astheylackthebeauty.Nowitbecomesapparentthatyoungpeoplenolongerlearncursive(草書).Theytypeeverything,mostlyontheirphones.Beautifulhandwritingisathingofthepast.Thishasbecomeasourceofgreatsadnessamongtraditionalists.Butrecentlysomethinghappenedthatshookmyfaithincursive.Tomycompletedisbelief,notonebuttwoofmyclosefriendscomplainedaboutthehandwritingonmypostcards.TheyweregratefulforthebeautifulpostcardsIregularlysent,buttheysaidtheyhonestlycouldn’treadathingIhadwritten.OnefriendwentsofarastoaskifIcoulduseblocklettersnexttimesothatshecouldunderstandwhatIwaswriting.Initially,Iwasangry.IhadmadetheefforttocoveranentirepostcardwithwhatIviewedasnotjusthandwritingbutcalligraphy.ButthenIshowedanEnglishfriendapostcardI’djustwritten,andhesaidthattheonlythingthatwasreadilyunderstandablewastheletters“U
