Unit 5 閱讀理解詞義猜測(cè)題做題技巧學(xué)案 高一英語(yǔ)人教版 2019 必修第一冊(cè)

第五單元如何做詞義猜測(cè)題題型特點(diǎn)詞義猜測(cè)能力是閱讀理解能力的主要組成部分,歷年高考都把猜詞能力作為考生應(yīng)該掌握的一項(xiàng)閱讀技能列入考試范圍,考查對(duì)文中實(shí)詞、短語(yǔ)等的理解。利用文中的舉例猜測(cè)詞義是最常用的方法之一,恰當(dāng)?shù)呐e例能夠?yàn)椴聹y(cè)生詞提供重要線索,文章中常用suchas,forexample,forinstance,like等引出例子,學(xué)生可以根據(jù)例子的隸屬類(lèi)別來(lái)猜測(cè)出畫(huà)線詞的詞義。解題策略1.利用定義語(yǔ)來(lái)猜測(cè)詞義在許多情況下,作者預(yù)計(jì)到一般讀者對(duì)某個(gè)詞不熟悉,則會(huì)在文章中給出該詞的定義或解釋。這種解釋可能是一種重復(fù)說(shuō)明或定義。通過(guò)閱讀定義或解釋部分,我們便可理解該詞的基本含義。線索詞有that,which,is等。2.利用定語(yǔ)或同位語(yǔ)來(lái)猜測(cè)詞義通常引出該詞同位語(yǔ)的詞語(yǔ)有or,thatis,inotherwords等,還有的同位語(yǔ)以括號(hào)或破折號(hào)的形式出現(xiàn)。在這些標(biāo)志后面我們可較容易地找到同畫(huà)線詞意義相同或相近的詞。3.利用文章中的舉例來(lái)猜測(cè)詞義在閱讀理解中我們可以根據(jù)文章中所舉的例子,從具體到一般,猜出該生詞的意思。4.利用對(duì)比或比較的詞語(yǔ)來(lái)猜測(cè)詞義當(dāng)作者強(qiáng)調(diào)的事物之間有區(qū)別或?qū)αr(shí),作者往往會(huì)運(yùn)用對(duì)比的手法,即會(huì)用到對(duì)比的詞語(yǔ),例如反義詞,暗示出生詞的含義。能體現(xiàn)對(duì)比關(guān)系的詞匯很多,主要有but,yet,however,while,unlike,instead,ontheotherhand,onthecontrary,incontrastwith等。標(biāo)點(diǎn)符號(hào)中的分號(hào)也可表示對(duì)比。5.利用構(gòu)詞法來(lái)猜測(cè)詞義分析復(fù)合詞:如果一個(gè)生詞是由兩個(gè)或兩個(gè)以上的單詞構(gòu)成的復(fù)合詞,則可以從該詞各個(gè)部分的特定意思及聯(lián)系上猜出該詞的意思。學(xué)生同時(shí)要了解構(gòu)詞法知識(shí),掌握大綱所要求的對(duì)前后綴的理解。6.利用因果關(guān)系來(lái)猜測(cè)詞義因果關(guān)系是一種常見(jiàn)的提供生詞詞義信息的邏輯關(guān)系。一定的原因會(huì)導(dǎo)致一定的結(jié)果,某一結(jié)果總是由某種或某些原因引起的。作者在敘述原因的過(guò)程中就必然會(huì)把詞或句子置于因果關(guān)系中。常見(jiàn)的表示因果關(guān)系的詞匯有:since,as,because,for,so,thus,consequently,therefore,hence,dueto,resultin,resultfrom,asaresult,forthisreason,accordingly,sothat,so…that,such…that等。真題解析ForCanaanElementary’ssecondgradeinPatchogue,N.Y.,todayisspeechday,andrightnowit’sChrisPalaez’sturn.The8-year-oldisthejokeroftheclass.Withshiningdarkeyes,heseemslikethekindofkidwhowouldenjoypublicspeaking.Buthe’snervous.“I’mheretotellyoutodaywhyyoushould…should…”Christripsonthe“-ld,”apronunciationdifficultyformanynon-nativeEnglishspeakers.Histeacher,ThomasWhaley,isnexttohim,whisperingsupport.“…Votefor…me…”Exceptforsomestumbles,Chrisisdoingamazinglywell.Whenhebringshisspeechtoaniceconclusion,Whaleyinvitestherestoftheclasstopraisehim.Asonofimmigrants,ChrisstartedlearningEnglishalittleoverthreeyearsago.Whaleyrecalls(回想起)howatthebeginningoftheyear,whencalledupontoread,Chriswouldexcusehimselftogotothebathroom.LearningEnglishasasecondlanguagecanbeapainfulexperience.Whatyouneedisagreatteacherwholetsyoumakemistakes.“Ittakesalotforanystudent,”Whaleyexplains,“especiallyforastudentwhoislearningEnglishastheirnewlanguage,tofeelconfidentenoughtosay,‘Idon’tknow,butIwanttoknow.’”Whaleygottheideaofthissecond-gradepresidentialcampaignprojectwhenheaskedthechildrenonedaytoraisetheirhandsiftheythoughttheycouldneverbeapresident.Theanswerbrokehisheart.Whaleysaystheprojectisaboutmorethanjustlearningtoreadandspeakinpublic.Hewantsthesekidstolearntoboast(夸耀)aboutthemselves.“Boastingaboutyourself,andyourbestqualities,”Whaleysays,“isverydifficultforachildwhocameintotheclassroomnotfeelingconfident.”Whatdoestheunderlinedword“stumbles”inparagraph2referto?A.Improperpauses.B.Badmanners.C.Spellingmistakes. D.Sillyjokes.語(yǔ)篇導(dǎo)讀本文由學(xué)生Chris發(fā)表競(jìng)選演說(shuō)的經(jīng)歷引出老師ThomasWhaley利用競(jìng)選演說(shuō)鼓勵(lì)同學(xué)們學(xué)會(huì)贊美自己,幫助其提升自信,走向成功。參考答案：A考查詞義猜測(cè)。根據(jù)文章內(nèi)容可知,老師借助競(jìng)選演說(shuō)鼓勵(lì)同學(xué)們學(xué)會(huì)贊美自己。文中ChrisPalaez的母語(yǔ)不是英語(yǔ),他學(xué)英語(yǔ)才三年多,說(shuō)話不流利,而且他在演講時(shí)非常緊張,所以說(shuō)話磕磕絆絆,因此選A。1.詞義猜測(cè)題考查考生根據(jù)上下文的語(yǔ)境推斷生詞詞義的能力,同時(shí)也考查考生對(duì)語(yǔ)境的正確分析和把握能力。該題型出現(xiàn)的題量不是很大,但是一般都有一定的難度,是具有區(qū)分度的題目之一。2.所猜測(cè)內(nèi)容一般是超綱的比較生僻的單詞或詞組,有時(shí)也會(huì)是一個(gè)句子。3.除了指代關(guān)系的設(shè)題,正確選項(xiàng)一般是該詞或詞組的近義詞或釋義。該近義詞或釋義能夠從該詞所在的句子上下文中得到足夠明確的信息。而錯(cuò)誤選項(xiàng)一般也可以通過(guò)上下文的語(yǔ)義予以排除。4.有時(shí)候,詞義猜測(cè)題考查的是一個(gè)單詞、詞組或句子的指代意義。這就要求考生要能夠準(zhǔn)確理解上下文,并且能夠理清相關(guān)句子的結(jié)構(gòu)。A組Passage1Moneywithnostringsattached.It’snotsomethingyouseeeveryday.ButatUnionStationinLosAngeleslastmonth,aboardwentupwithdollarbillsattachedtoitwithpinsandasignthatread,“GiveWhatYouCan,TakeWhatYouNeed.”
