說明文類語篇通常遵循一種清晰的結構，它由三個核心部分構成：引出主題、主題展開和主題深化。在引出主題的環(huán)節(jié)，作者常采用提問法、事例法、反襯法和直白法。這四種方法每一種都有其獨特的表達效果，共同的目標是幫助讀者迅速把握語篇的主旨。例如，事例法通過講述一個引人入勝的故事，引導讀者自然地進入語篇的主題。相對地，反襯法則通過展示事物之間的差異，強化了主題在讀者心中的印象。掌握這四種說明文主題的引出方法，考生們將能夠更加熟練地識別和理解說明文的核心議題，從而快速進入語篇的深層意義中。這對于提升閱讀理解能力以及答題效率的提升至關重要。因此，考生應重視培養(yǎng)快速識別說明文主題意義的能力，并通過持續(xù)的訓練，精進自己的閱讀技巧。這樣，在面對說明文閱讀時，無論是日常學習還是考試環(huán)境，都能夠游刃有余。一、說明文引出主題的四種常見方法以下語段都來自說明文語篇的第一段，并包含主題句。如果沒有主題句，考生需要概括和提煉。通過明晰四種方法如何被用來引出說明文語篇的主題意義，考生能獲取結構化的閱讀策略知識，從而明顯提升在主題獲取方面的效率和準確性。1.提問法：語篇開篇即提出一個問題，接下來給出問題答案，即本說明文語篇的主題。利用提問法引出主題，能夠立即激發(fā)讀者的好奇心，驅使他們繼續(xù)閱讀以尋找答案?！癏aveyoueverwonderedhowasimpleseedtransformsintoatoweringtree，defyingtheoddsoftimeandnature？Themiraculousprocessofphotosynthesis（光合作用），theverylifebloodofourplanetsgreenery，holdsthekeytothisremarkabletransformation.”方法闡釋：主題句為“Themiraculousprocessofphotosynthesis，theverylifebloodofourplanetsgreenery，holdsthekeytothisremarkabletransformation.”在呈現該主題句之前，作者通過提問引發(fā)讀者對種子成長為大樹過程的思考，進而揭示語篇所探討的主題意義：光合作用這一神奇過程，它是地球上綠色植被生命力的源泉，解釋了植物如何克服自然挑戰(zhàn)，實現驚人成長。2.事例法：通過敘述具體的事例或故事來引入主題，這種方法使抽象的概念通過生動的情節(jié)變得具體可感?！癐ntheheartoftheAmazonrainforest，atinysaplingstrugglestobreakthroughthedensecanopy（樹冠層），reachingforthelightabove.Thistaleofperseverancemirrorsthejourneyofcountlessspeciesadaptingtotheirenvironments，atestamenttothepowerofadaptationinnature.Today，wedelveintothemechanismsthatdrivethisremarkableadaptability.”方法闡釋：主題句為“Today，wedelveintothemechanismsthatdrivethisremarkableadaptability.”通過講述亞馬遜雨林中小樹苗奮力穿透茂密樹冠、追求光線的生動事例，語篇引出了自然界中生物適應環(huán)境的重要性及其背后的機制。主題句明確指出，語篇將要深入探討推動生物非凡適應能力的原理。3.反襯法：利用對比或對照的手法，將不同事物并置，以此凸顯主題的獨特屬性，增強主題的顯著性?！癢hilethebusycityscapeofTokyothrivesontechnologyandinnovation，thepeacefulricefieldsofKyotowhispertalesofancienttraditionsandharmonywithnature.ThisstrikingcontrastbetweenmodernityandtraditionhighlightsthedualnatureofJapansculturalidentity.Yet，attheheartofthisdifferenceliesasharedcommitmenttopreservingandinnovating，abalancethatfewsocietieshaveachieved.”方法闡釋：主題句為“Yet，attheheartofthisdifferenceliesasharedcommitmenttopreservingandinnovating，abalancethatfewsocietieshaveachieved.”通過對比東京的繁華與科技創(chuàng)新和京都稻田的寧靜與傳統，語篇揭示了日本文化身份中的二元性。主題句強調，盡管存在這種明顯的對比，但兩者都共享著對保護和創(chuàng)新的承諾，這種平衡是許多社會難以達到的，從而引出語篇將要探討的主題——如何在現代化進程中保持文化傳統的平衡。4.直白法：直接切入主題，以簡潔明快的方式向讀者明確傳遞語篇的中心思想，避免了冗長和拐彎抹角。“Climatechangeposesanexistentialthreattoourplanet，requiringimmediateandglobalaction.Thisarticleexaminesthecurrentstateofclimatescience，theimpactsofrisingtemperatures，andtheurgentneedforsustainablesolutionstoeaseitseffects.”方法闡釋：主題句為“Climatechangeposesanexistentialthreattoourplanet，requiringimmediateandconcertedglobalaction.”語篇開篇即直接指出氣候變化對地球構成的生存威脅，并強調需要立即采取全球性的協同行動。主題句明確無誤地傳達了語篇的主題意義：分析氣候科學的現狀、氣溫上升的影響，以及提出緩解這些影響的緊迫需求。二、四種方法在2023年全國卷語篇中的運用示例在高考英語2003年全國卷試題中，多篇說明文語篇通過提問法、事例法、反襯法和直白法引出所要說明的主題對象。以下是其中四個語篇示例，有利于考生閱讀策略知識的進一步結構化。（2023年全國甲卷七選五）TricksToBecomingAPatientPersonHeresariddle：Whatdotrafficjams，longlinesandwaitingforavacationtostartallhaveincommon？Theresoneanswer.16.""""""".IntheDigitalAge，wereusedtohavingwhatweneedimmediatelyandrightatourfingertips.However，researchsuggeststhatifwepracticedpatience，wedbeawholelotbetteroff.Hereareseveraltricks.●Practicegratitude（感激）Thankfulnesshasalotofbenefits：Researchshowsitmakesushappier，lessstressedandevenmoreoptimistic.17.""""""".“Showingthankfulnesscanfosterself-control，”saidYeLi，researcherattheUniversityofCalifornia.●MakeyourselfwaitInstantgratification（滿足）mayseemlikethemost“feelgood”optionatthetime，butpsychologyresearchsuggestswaitingforthingsactuallymakesushappierinthelongrun.Andtheonlywayforustogetintothehabitofwaitingistopractice.18..Putoffwatchingyourfavoriteshowuntiltheweekendorwait10extraminutesbeforegoingforthatcake.Youllsoonfindthatthemorepatienceyoupractice，themoreyoustarttoapplyittoother，moreannoyingsituations.●19."""""".Somanyofushavethebeliefthatbeingcomfortableistheonlystatewewilltolerate，andwhenweexperiencesomethingoutsideofourcomfortzone，wegetimpatientaboutthecircumstances.Youshouldlearntosaytoyourself，“20."""""""".”Youllthengraduallybecomemorepatient.A.FindyourcausesB.StartwithsmalltasksC.AccepttheuncomfortableD.AllthisaddsuptoastateofhurryE.ItcanalsohelpuspracticemorepatienceF.Thisismerelyuncomfortable，notintolerableG.Theyreallsituationswherewecouldusealittleextrapatience（答案：GEBCF）示例分析：本語篇第一段和第二段可以結合在一起進行閱讀，其使用提問法引出主題：成為耐心之人的技巧（However，researchsuggeststhatifwepracticedpatience，wedbeawholelotbetteroff.Hereareseveraltricks.）這種提問的引入方式激發(fā)了讀者的好奇心。接著，語篇在隨后的內容中揭示了這些情境的共同點是它們都需要我們展現出更多的耐心。明白此種引出主題的方法能幫助考生快速把握語篇的主旨，即探討如何成為更有耐心的人。在明晰語篇主題意義后，考生能將文本中各段的意義迅速串聯起來，從而為后面的解題分析提供支持。（2023年新課標II卷C篇）ReadingArt：ArtforBookLoversisacelebrationofaneverydayobject—thebook，representedhereinalmostthreehundredartworksfrommuseumsaroundtheworld.Theimageofthereaderappearsthroughouthistory，inartmadelongbeforebooksaswenowknowthemcameintobeing.Inartistsrepresentationsofbooksandreading，weseemomentsofsharedhumanitythatgobeyondcultureandtime.Inthis“bookofbooks，”artworksareselectedandarrangedinawaythatemphasizestheseconnectionsbetweendifferenterasandcultures.Wes
