押湖南卷第28-31題 說(shuō)明文閱讀（原卷版）-備戰(zhàn)2024年中考英語(yǔ)臨考題號(hào)押題

押湖南卷第28-31題閱讀理解之說(shuō)明文閱讀【題型概述】說(shuō)明文是對(duì)客觀事物的性狀、特點(diǎn)、功能和用途等作科學(xué)解說(shuō)的。它既不像記敘文那樣重在情節(jié)的敘述和描寫(xiě)，也不像議論文那樣，重在闡明主張和論點(diǎn)論據(jù)；說(shuō)明文是通過(guò)解說(shuō)事物、闡明事理，說(shuō)明文是中考英語(yǔ)閱讀理解題中的重點(diǎn)，難點(diǎn)之一。說(shuō)明文具有與自己特點(diǎn)相適應(yīng)的說(shuō)明方法，因此說(shuō)明文結(jié)構(gòu)復(fù)雜，專(zhuān)業(yè)術(shù)語(yǔ)多，易于拉開(kāi)考生分?jǐn)?shù)檔次，對(duì)于考生來(lái)說(shuō)說(shuō)明文抽象度高，解題難度大。因此考生要掌握說(shuō)明文的命題特點(diǎn)，敘述方式，以冷靜的心態(tài)閱讀原文，重點(diǎn)突破長(zhǎng)句結(jié)構(gòu)特點(diǎn)和邏輯關(guān)系，以便對(duì)其做出準(zhǔn)確的語(yǔ)意理解?！鹃喿x策略】二、出題特點(diǎn)1.

生詞詞義判斷題；2.

標(biāo)題判斷題；3.

主旨大意題；4.

文章結(jié)構(gòu)題；5.

觀點(diǎn)態(tài)度題。三、閱讀方法閱讀說(shuō)明文的關(guān)鍵：抓住事物的特點(diǎn)，即抓住說(shuō)明對(duì)象的本質(zhì)特征。1.

明確說(shuō)明對(duì)象。閱讀事物說(shuō)明文，首先從整體入手，把握文章的說(shuō)明對(duì)象是什么；閱讀事理說(shuō)明文，首先弄清文章說(shuō)明了什么事理?？梢酝ㄟ^(guò)把握段落主題句來(lái)明確說(shuō)明對(duì)象。2.

逐段概括要點(diǎn)，理清說(shuō)明順序。概括要點(diǎn)要重視首尾句的作用，重視概念句或解說(shuō)性語(yǔ)句的作用。閱讀時(shí)可以把這些語(yǔ)句勾畫(huà)出來(lái)。3.

整體感知，把握中心。分析文章段落之間是并列、遞進(jìn)還是總分關(guān)系；是由現(xiàn)象到本質(zhì)，還是由個(gè)別到一般，或是從結(jié)果到原因。最后總結(jié)出文章的中心思想。四、解題技巧1.

閱讀做標(biāo)記。在閱讀的時(shí)候可給段落標(biāo)上序號(hào)，并給重要的句子和關(guān)鍵詞匯做上記號(hào)，尤其是各段中心句，為答題提供更快捷、更多的信息。2.

審清題干。發(fā)掘和把握試題中有效的提示性信息，確認(rèn)命題的角度、閱讀范圍和答題方式。3.

定位閱讀,強(qiáng)化對(duì)應(yīng)意識(shí)。絕大部分的說(shuō)明文閱讀題都有一個(gè)共性，那就是答案基本上都能直接和間接從選段中找到依據(jù)。回答問(wèn)題時(shí)要注意原文利用和自我加工相結(jié)合。PassageA（2023湖南長(zhǎng)沙卷）AnyonewhohasseenTheSoundofMusic,theOscar-winningmovie,knowsthefamouscityofSalzburginAustria.Themusicalmoviewasfilmedinandaroundthecity.Toenjoytheamazing(令人驚嘆的)city,youonlyhavetowalkthroughthealleys(小巷).ThesoundsofmusicinSalzburgarenotjustfromthefamousfilm.Mozart,oneofthegreatestmusicians,wasbornhere,andthecityisproudofhim.You’llhearMozart’smusicalloverthecity.AndyoucanvisitMozart’sbirthplace,learnabouthischildhoodandeventrythechocolatenamedforhim:aMozartball!Don’tmissvisitingtheSalzburgResidenz,whichwastherulers’palaceinthepast.ItwasherethatMozartperformed(表演)forthefirsttimeinhislife.AvisittoSalzburginDecembermustincludetimeintheChristmasmarkets,whichcanbefoundhereandthere.Visitthemarketplacesforahotdrink.Thenenjoythebeautifulhandiworkforsale.SaltwassoimportanttothecityofSalzburgthatthecitywasnamedforit.This“whitegold”broughtwealthtotherulers.YoucanvisittheHalleinSaltMine(礦),oneoftheoldestintheworld.Takeatrainrideintothemountain,whereminerswillexplaintheminingprocess(過(guò)程).Thenenjoyaboatrideacrossanundergroundlake.ThesearejustafewoftheenjoyableplacesinthissmallAustriancity.Therearemuchmorewaitingforyoutoexplore.Makesuretoplanatriptothisbreathtakingcity.Itshistoryandculturewillexciteyoursenses.26.WhatdoweknowaboutTheSoundofMusic?A.ItwasfilmedbyMozart.B.ItisanOscar-winningmovie.C.ItisamovieofSalzburg’schocolate.27.WheredidMozartperformforthefirsttimeinhislife?A.InaChristmasmarket.B.AttheHalleinSaltMine.C.AttheSalzburgResidenz.28.Whatisthe“whitegold”inParagraph4?A.Salt.

推斷題推理是在既有信息的基礎(chǔ)上得出合乎文章內(nèi)容的內(nèi)涵意義，即某一問(wèn)題、某一觀點(diǎn)沒(méi)有直接表述，而寓意在文章的字里行間，要求通過(guò)文中信息分析推出某種符合作者思想、符合文章邏輯的內(nèi)涵意義。推斷則是指通過(guò)對(duì)文章進(jìn)行符合邏輯的綜合分析，推出文章未直接陳述的言外之意。推斷題推斷得正確與否，很大程度上取決于是否能正確把握作者潛隱在字里行間的語(yǔ)氣及觀點(diǎn)。（1）事實(shí)推斷。這種推斷常常針對(duì)某一個(gè)或幾個(gè)具體細(xì)節(jié)，是比較簡(jiǎn)單的推斷。進(jìn)行這種推斷，要首先在文章中找出據(jù)以推斷的有關(guān)文字，然后加以分析，尤其要悟出字里行間的意思。（2）指代推斷。確定指代詞的含義和指代對(duì)象是閱讀理解題常見(jiàn)的題目。要確定指代詞所指代的對(duì)象，關(guān)鍵在于對(duì)上下文的正確理解。指代名詞的指代詞，其單復(fù)數(shù)形式應(yīng)與被指代的詞一致，因此數(shù)的形式可作為識(shí)別指代對(duì)象的第一個(gè)輔助標(biāo)志。（3）邏輯推斷。這類(lèi)題目往往是要求根據(jù)文章所提供的背景、人物的表情、動(dòng)作和語(yǔ)言來(lái)推斷出人物的態(tài)度或感受。（4）對(duì)作者的意圖和態(tài)度的推斷。這一類(lèi)考題大都要求學(xué)生就作者對(duì)論述對(duì)象持什么樣的態(tài)度做出推斷，如作者對(duì)所陳述的觀點(diǎn)是贊同、反對(duì)，還是猶豫不定，對(duì)記述或描寫(xiě)的人、物或事件是贊頌、同情、冷漠，還是厭惡。作者的這種思想傾向和感情色彩不一定直接表述出來(lái)，而往往隱含在字里行間。因此，進(jìn)行這種推斷時(shí)，我們既要依靠短文的主題思想作為推力的前提，又要注意作者的措辭，尤其是形容詞一類(lèi)的修飾語(yǔ)。總之，只要平時(shí)善于積累，并熟練運(yùn)用上述解題技巧，初中閱讀理解題就將不再是難題。三、

猜測(cè)詞義題閱讀短文時(shí)，常常會(huì)遇到一些生詞。這時(shí)，考生要沉著、冷靜，細(xì)心思考。首先要把整段、整篇文章看完。通過(guò)對(duì)全篇短文的理解，就有可能猜測(cè)出生詞的大意。另外，還可以從含有生詞句子的上下文，以及句子和段落之間的關(guān)系來(lái)判斷、理解生詞以求獲得其真正含義。猜測(cè)生詞的另一種方法是，根據(jù)構(gòu)詞法推測(cè)。遇到生詞后，可從構(gòu)詞法角度分析判斷生詞。例如：

inexpensive一詞，其中詞根expensive的含義是“貴的”。前綴in是“不”的意思，因此可以猜測(cè)此詞詞義為“不貴的，便宜的”?？傊?，猜詞題可以用到以下技巧（1）.
