1、第三講主旨大意題整體感知明方向主旨大意題是閱讀理解中考生失分最多的題目，因為該類試題不僅考查考生略讀文章、領(lǐng)會大意的能力，也對考生的歸納、概括能力提出了較高的要求。文章中沒有明顯的解題依據(jù)，需要考生從文章中提煉、抽取一些關(guān)鍵詞、主干句進行加工概括，才能歸納出文章的主旨。此類題目可分為三大類，即標題歸納題、文章大意題和段落大意題。要做好主旨大意題，我們首先必須了解其正確選項和干擾選項的特征。常見設(shè)問方式1標題歸納題The best title of the passage is _.Which of the following is the best title of the passage?W

2、hat would be the best title for the passage?The most appropriate title of the passage is _.2文章大意題Whats the main idea/point of the passage?The passage is mainly about _.What is the text mainly about?The general/main idea of the passage is about _.3段落大意題What does the author tell us in Paragraph.?The m

3、ain idea of the second paragraph probably is _.The first paragraph is mainly about _.Which of the following can best summarize Par.1？正確選項特征干擾選項特征1.涵蓋性強，覆蓋全文或全段。2.確定的范圍恰當，既不太大，也不太小。3.精確性強，不會改變語言表意的程度及色彩。1.過于籠統(tǒng)，不知所云所給選項內(nèi)容概括的范圍過大，超出文章所述內(nèi)容。2.以偏概全，主次不分所給選項只闡述了文章的一部分內(nèi)容，或以文章中的細節(jié)信息或個別詞為選項的設(shè)置內(nèi)容，或以次要的事實或細節(jié)充當全

4、文的主要觀點。3.移花接木，偷換概念所給選項被命題者有意識地把本屬于A的內(nèi)容放在B上，若不留神，極易選錯答案。4.無中生有，生搬硬套所給選項的關(guān)鍵詞語雖然在文章中談到了，但經(jīng)過仔細閱讀分析之后，發(fā)現(xiàn)選項的內(nèi)容與文章的內(nèi)容毫無聯(lián)系。分類例析通技法標題歸納題解題攻略理解標題的3大特點，巧用3大方法確定文章標題一個好的標題應(yīng)具備三大特點：1概括準確而又簡短；2針對性標題外延正好與文章內(nèi)容相符；3醒目能引發(fā)讀者的閱讀欲望。因此有必要掌握以下三大方法：1正面肯定法：在理解文章主旨的基礎(chǔ)上，揣摩哪個選項能準確概括主旨；2反面否定法：撇開原文，拿各個備選項去設(shè)想用它們寫出來的“文章”將是什么內(nèi)容，然后和原文

5、章對照，一一排除不符選項；3研讀備選項本身：研讀備選項里面的中心詞、修飾詞的變化、結(jié)構(gòu)、概括性等。典例(2019全國卷，閱讀D)Bacteria are an annoying problem for astronauts.

11、殺死國際空間站的細菌。第二步析選項，斟酌判斷ANASA：宇航員的家文中雖提到有關(guān)NASA方面的內(nèi)容，但這不是文章主要內(nèi)容。以偏概全，主次不分B太空：高中生前沿研究Space對應(yīng)太空研究，F(xiàn)inal Homework對應(yīng)高中教育，F(xiàn)rontier突出了領(lǐng)先性涵蓋性強，覆蓋全文C大自然：一個課外教室并不聚焦太空領(lǐng)域無中生有DHUNCH：大學(xué)入學(xué)改革HUNCH主要是太空研究無中生有答案B文章大意題解題攻略掌握尋找主題句的4個小竅門，快速確定文章大意文章是由段落組成的。段落的主題就是段落的中心思想，具體段落的中心思想又是為文章整體中心思想服務(wù)的。理解整篇文章的中心思想的方法是建立在理解具體段落中心的基

12、礎(chǔ)上的。找出每小段的主題句，各段的主題句常在該段的首句或尾句，各段主題句的整體歸納便是文章的中心思想。有的文章無明顯主題句，主題句隱含在段意之中，這就需要進一步加工概括。觀察全文的結(jié)構(gòu)安排，理解文章的“重心”和支撐性細節(jié)。 用瀏覽法(skimming)，即快速閱讀文首、文尾，或每段的首句和尾句等，搜索主題線索和主題信息的方法可以快速找到主題句。 以下是找主題句的四個小竅門：1段落中出現(xiàn)表示轉(zhuǎn)折的詞語(如however，but，in fact，actually等)時，該句很可能是主題句。2首段出現(xiàn)疑問句時，對該問題的回答很可能就是文章主旨。3作者有意識地重復(fù)的觀點，通常是主旨；反復(fù)出現(xiàn)的詞語，一

13、般為體現(xiàn)文章主旨的關(guān)鍵詞。4表示總結(jié)或結(jié)論的句子常包含therefore，thus，in short，conclude，conclusion等詞。典例(2019全國卷，閱讀C)Marian Bechtel sits at West Palm Beachs Bar Louie counter by herself，quietly reading her ebook as she waits for her salad.What is she reading？None of your business！Lunch is Bechtels “me” time.And like more Americ

20、生搬硬套C加班帶來的壓力文中有提到，但不是本文的重點以偏概全，主次不分D無線科技的優(yōu)點，文中沒有提到無中生有，生搬硬套答案A段落大意題解題攻略歸納段落大意的2種方法方法1概括段落大意要準確概括某段的大意，務(wù)必要知道該段的邏輯結(jié)構(gòu)。(1)如果該段是按總分順序組織，首句做總的說明，其他句子對其進行具體論述，這種結(jié)構(gòu)的主題句就在段首；(2)如果按分總順序組織，主題句就在段尾；(3)如果按分總分的順序組織，則主題句就在這段話的中間；(4)如果按總分總的順序，段落結(jié)構(gòu)相對難度較低，我們可以很明顯的看到一段的首句和末句的內(nèi)容幾乎完全一致，正確答案就呼之欲出了；(5)如果按并列式行文，這種結(jié)構(gòu)的段落一般會在

21、一段中討論兩個平行的內(nèi)容，整個段落可以從中間處分開，前后是平行關(guān)系，這樣的段落結(jié)構(gòu)對應(yīng)的答案通常也會是很明顯的并列關(guān)系；(6)如果對比各事物，那么它們的共同點或不同點就是該段大意。方法2揣摩段落大意有時，作者可能不直接寫出主題句，而是通過各種方法暗示給讀者，這就需要充分發(fā)揮讀者的想象力與判斷力，揣摩段落大意。典例(2019江蘇卷，閱讀B節(jié)選)Most of us，when we talk about volcanoes，think of the classic cone(圓錐體)shapes of a Fuji or Kilimanjaro，which are created when eru

25、段意本段主要講述了兩種火山的形狀。第二步析選項，斟酌判斷A火山的形狀A(yù)項是對本段內(nèi)容的精煉概括和總結(jié)。涵蓋性強，覆蓋全段B火山的影響本段沒有提到無中生有，生搬硬套C火山的活動本段確實說到了火山的活動，但不是本段主流。以偏概全，主次不分D火山的高度本段只提到一句，無足輕重以偏概全，主次不分答案A小題夯基練1Steven Stein likes to follow garbage trucks.His strange habit makes sense when you consider that hes an environmental scientist who studies how to

51、 Magic Bench allows groups of people to gather in a single environment and collectively participate in an augmented reality(擴充實境)experience，all at the same time”可知，與傳統(tǒng)移動技術(shù)不同的是，傳統(tǒng)移動技術(shù)的限制之一是只有一個用戶可以看到這種互動，而Magic Bench允許一群人聚集在一個單獨的環(huán)境中集體同時參與互動體驗。故C項正確。4Which is the best title of the text?AMagic Bench Pu

60、r.DSuggestion from the hairstylist.解析：B考查推理判斷。根據(jù)第三段的內(nèi)容，尤其是“Grimm thought about Prisilla.she had an idea：Cut off her hair”可知，Prisilla因為是短頭發(fā)而被同學(xué)嘲笑，為了安慰Prisilla，Grimm 老師決定把自己的頭發(fā)剪短。由此可推知，Grimm老師出于對學(xué)生的關(guān)愛才剪短了頭發(fā)。7What can we know about Grimm?AShe had her hair cut together with Prisilla.BShe expressed her s

61、incere thanks to her pupils.CShe hesitated a lot before having her hair cut.DShe won a gold medal for facing difficulties bravely.解析：C考查細節(jié)理解。根據(jù)第三段第二句中的“Ive never had short hair，and I stressed about it for two weeks before making a decision”可知，Grimm 老師剪短頭發(fā)之前很猶豫。8What is the text mainly about?AHow Gri
