歷年考情說明文閱讀理解一般作為全國卷閱談理解中的CD實驗研究和介紹說明型明文是對事物的形狀，性質，特征，成果或公用等進行介紹，解釋或闡述的文章，把我所說明事物的特征圖標法，引用法和距離法等。說明文的特點是客觀、簡潔、準確、清晰，文章很少表達作者的情感傾向。閱讀說明文的重點在于讀懂它說明的事物或事理，了解事物的性質、結構、形成原因、功能；了解事物的意義和特征等。命題規律說明文所選材料題材豐富多樣，涉及社會、科技、文化、生活、人物、教育、生態、安全等方面。在把握語篇整體結構，還要求學生有大量的閱讀積淀和知識儲備，熟悉不同的話題和不同的題目考查方式。即便是細節理解題，大多數情況下考生也無法從文章中直接找到與選項表述完全一致的信息，而是需要在理解文章細節信息后作出歸納和判斷。通常一套卷中主旨大意、詞義猜測、寫作意圖/觀點態度類高難度試題的考查數量為2道左右，說明文考查此類題目的頻率較高，且命題點呈多樣化。考向預測預測2025年高考說明文閱讀理解試題難度會保持相對穩定，主要考查題型仍然為細節理解題和推理判斷題為主，主旨大意題和詞義猜測題為輔。1/【全國甲卷】Animalscanexpresstheirneedsusingalotofways.Forinstance,almostallanimalshavedistinctvocals(聲音)thattheyrelyontoeitheraskforhelp,scareawayanydangerousanimalsorlookforshelter.Butcatsarespecialcreatureswhopossessamazingvocalizationskills.Theyareabletohaveentireconversationswithhumansusingmeowsandyou'reabletointerpretit.Ifapetcatishungry,itwillkeepmeowingtoattractattentionandfindfood.However,whenacatislookingforaffection,theytendtoproducestretchedandsoftmeows.Meowingstartsassoonasababycatisbroughttolifeandusesittogetthemother'sattentionandbefed.Catshavemanyheightenedsenses,buttheirsenseofsmellisquiteimpressive.Theyusetheirnosestoassesstheirenvironmentandlookoutforanysignsofdanger.Theywilloutspecificareasbeforetheychooseaplacetorelax.However,anotherwaythecatsareabletodistinguishbetweensituationsisbylookingforfamiliarsmells.catwilllikelysmellyourfaceandstorethesmellinitsmemoryanduseittorecognizeyouinthefuture.That'swhymostpetcatsareabletotellimmediatelyiftheirownerswerearoundanyothercats,whichtheydon'tusuallylike.Dogsareknownfortheirimpressivefetchinghabit,butcatstakethisbehaviorupanotch.Manycatswillfindrandomobjectsoutsideandbringthemtotheirowners.Thisisaveryoldhabitthat'sbeenpresentinallkindsofpredators(食肉動物).Catsbringgiftsfortheirownerstoshowtheyloveyou.Theseadorablelittlehuntersarejustdoingsomethingthatit'sbeenintheirnaturesincethebeginningoftime.Sojustgoalongwithit!4.Whatcanbelearnedaboutcats'meowingfromthefirstparagraph?A.It'sasurvivalskill.B.It'staughtbymothercats.C.It'shardtointerpret.D.It'sgettinglouderwithage.5.Howdoesapetcatassessdifferentsituations?A.Bylisteningforsounds.B.Bytouchingfamiliarobjects.C.Bycheckingonsmells.D.Bymunicatingwithothercats.6.Whichbestexplainsthephrase"take...upnotch"inparagraph3?2/A.Performappropriately.B.Movefaster.C.Actstrangely.D.Dobetter.7.Whatisasuitabletitleforthetext?A.onFindingaSmartCatB.UnderstandingCat'sBehaviorC.HaveFunwithCatD.HowtoKeepCatHealthy說明文閱讀量大，生僻詞匯多，句式結構復雜，這就需要考生有方法有技巧地去閱讀。一般我們采用的方法有三個：細讀、略讀和跳讀。（1）細讀重點。重點，就原文而言，就是文章的基本結構、內容和態度；就答題而言，就是問題所對應的題源句。以這個標準來衡量，需要重點閱讀的原文詞句就不會很多。宏觀方面：文章結構；文章主題句；各段首末句；體現作者觀點態度的詞句。微觀方面：有轉折處；重要標點；句子主干。（2）有選擇地略讀或跳讀。在快速瀏覽了題干，初步把握了文章大意及結構的基礎上，可大膽進行略讀或跳讀，這樣不但可以加快閱讀速度，還更容易總體把握全文。在閱讀中可略讀或跳讀的內容包括：①繁瑣的例證。為了說明問題，作者可能會借用形象的例子，有時候會比較繁瑣，雖能說明問題，但需要讀者花很多時間去閱讀。如果例子所說明的問題不明了，可通過略讀來理解；若例子所說明的問題比較明了，則例子部分可一帶而過。②并列多項列舉。有時許多功能相同的項目并列列舉，那么只讀其中一兩項即可，無需全讀。③無關大局的生僻詞匯。閱讀中經常會遇到一些生詞，如果這些生詞對理解全文沒有影響或影響不大就可略過。④較長的人名、地名。有許多較長的表示人名、地名等的專有名詞，閱讀時可一掃而過或干脆用其首字母代替，不必試圖把整個專有名詞讀出來。在略讀過程中，要特別注意對解題有重要意義的詞、句、段等，并將其儲存在大腦里，以免回頭再查看費時費力。【2025Envisionafuturisticrooftopgardensoastutethatitiscapableofdiscerningtheoptimalmomentstohoardwaterinanticipationofaridconditions,andwhentoexpelwatertoavertinundation.Now,suchintelligentroofsaretransitioningfromtherealmoffantasytorealityintheNetherlands.asubstantialportionofthenationsituatedbelowsealevel,theNetherlandshaslongbeenacquaintedwiththeperilsofflooding.Theadventofclimatechangehasusheredinaneraofmoreextrememeteorological3/phenomena,includingtorrentialdownpoursandperiodsofdrought,pellingthecityofAmsterdamtocontemplatenovelstrategiesforselfpreservation,anditiswithinthiscontextthatResilioemergesasapivotalplayer.Aspertheassertionsontheirwebsite,ResilioisengagedintheconstructionofbluegreenroofsacrosstheexpanseofAmsterdam.Inconjunctionwiththelocalgovernmentalauthorities,fromtheyears2018throughto2022,theyhaveinstalledspecializedroofingsystemsintheneighborhoodsofAmsterdamthataremostvulnerabletotheravagesofflooddamage.Theseroofsareposedofamultitudeofstrata.Paramountamongtheselayersisthewaterretentionlayer.Duringepisodesofcopiousrainfall,thislayerservestoaccumulatetherainwaterthatwouldotherwiseinundatethestreets,andintimesofdrought,itchannelsitsstoredwatertonourishthegardensituatedontheuppermostlayer.Itisthisparticularlayerthatdistinguishesthebluegreenroofsfromtheirconventionalgreencounterparts.Researchindicatesthatbluegreenroofspossessthecapacitytocaptureasmuchas97%ofextremerainfall,instarkcontrasttothemere12%thatregulargreenroofscanretain.However,whattrulysetsResilioroofsapartistheirsophisticatedsystems.Anarrayofbluegreenroofsareinterconnectedviaadigitalmunicationnetwork,therebyenablingeachrooftobemanipulatedindependently,respondingtothevolumeofwateramassedonthatspecificroofasthesituationdemands.EachroofisalsoequippedwithavalvethatislinkedtoaputerizedsystemknownastheDecisionSupportSystem(DSS).TheDSSinterfaceswithlocalweatherprognosticationstodeterminewhetherthevalveonaparticularroofshouldbeopened,allowingwatertobedischargedinacontrolledandgradualmannerintotheseweragesystem,
