第二部分/专题17词义猜测题考纲展示命题探究1命题方式的特点词义猜测是英语阅读的重要技巧,词义猜测题也是高考中常考的题型。考生要学会“顺藤摸瓜”,通过构词、定义、对比、因果、联想、上下文等线索(各种已知信息)确定词义。要求猜测词义的词一般为实词(动词、名词、形容词等)。另外,这类题也包括对短语和句意的猜测。考试中经常考查的词汇有以下几种:(1)在特殊语言环境中具有特殊意义的常用词。(2)专业化程度较高的词。(3)生僻词。(4)常用代词。2常见设问形式(1)Theunderlinedphrase“________”inthesecondparagraphcouldbereplacedby________.(2)Theunderlinedword“________”inthefirstparagraphprobablymeans________.(3)Whatisthemeaningoftheunderlinedwordinthesecondparagraph?(4)Whichofthefollowingisclosestinmeaningtotheunderlinedword“________”?(5)Whatdoestheunderlinedword“________”inParagraph2referto?(6)Whatdoyouthinktheexpression“________”standsfor?(7)Whichofthefollowingwordscanbesttaketheplaceoftheunderlinedword“________”inParagraph3?(8)Accordingtothepassage,theunderlinedword“________”isknownas________.3选项特点(1)正确选项的特点①相应词语的同义词语。②对相应语句的解释、复述或概括。(2)干扰项的特点①对原相应表达方式的不正确改写。②故意丢三落四。③包含该词或短语的基本意思,而非在文章中的含义。④望文生义项,即从原文表面理解该项为正确答案,但深层含义未在其中。⑤半对半错。⑥曲解原意。这些干扰项有时会使用较多原句中的表达方式,给人似是而非的误导,考生要多加注意。4猜测词义题的解题方法(1)利用指代关系来猜测代词词义代词词义的猜测即找出人称代词、指示代词或关系代词所指代的内容。对于代词所指代的内容的判断,首先我们要连读前后段落,了解前后两段文章的内容,然后判断所画线代词的类型。接下来仔细阅读前句,一般来说代词的词义推测主要是看前面句子所出现的名词及相当于名词的表达。(2)利用定义语来猜测词义在许多情况下,作者预计到某个词一般读者不熟悉,则会在文章中给出该词的定义或解释。这种解释可能是一种重复说明或定义。通过阅读定义和解释部分,读者便可理解该词的基本含义。线索词有that,which,is等。(3)利用定语或同位语来猜测词义通常引出该词同位语的词语有or,thatis,inotherwords等,还有的同位语以括号或破折号的形式出现。在这些标记词后考生可较易找到同画线词意义相同或相近的词。(4)利用文章中的举例来猜测词义在阅读理解中考生可以根据文章所举的例子,从具体到一般,猜出该生词的意思。(5)利用对比或比较的词语来猜测词义当作者强调的事物之间有区别或对立时往往会运用对比的手法,即会用到对比的词语,例如反义词,也可以暗示出生词的含义。注意这些词语和内容则能帮助判断所需内容。能体现对比关系的词汇很多,主要有but,yet,however,while,unlike,instead,ontheotherhand,onthecontrary,incontrastwith等。标点符号中的分号也可表示对比。(6)利用构词法知识来猜测词义分析复合词:如果一个生词是由两个或两个以上的单词构成的复合词,可以从该词各个部分的特定意思及联系上猜出该词的意思。学生同时要了解构词法知识,掌握大纲所要求的对前后缀的理解。(7)利用上下文语境来猜测词义通过对对应结构或平行结构中的同义词、反义词进行推断来猜测词义。(8)利用因果关系来猜测词义因果关系是一种常见的、行之有效的提供生词词义信息的逻辑关系。一定的原因会导致一定的结果,某一结果总是由某种或某些原因引起的。作者在叙述原因的过程中就必然会把词或句子置于因果关系中。常见的表示因果关系的词汇有:since,as,because,for,so,thus,consequently,therefore,hence,dueto,resultin,resultfrom,asaresult,forthisreason,accordingly,sothat,so...that,such...that等。[考法综述]此类题旨在考查考生在特定语境中理解词(短语、句子)的能力以及通过上下文或构词法猜测超纲词汇或表达方式的意义的能力。因此,考生所掌握的词汇量的大小直接影响到这类题的得分率。命题法1词汇意义猜测题典例1SituationⅣQ:IfIremembermyfriend'sbirthdayadaylate,shouldIapologizeorjustwishherahappybirthdaylikenothinghappened?A:Thisisthereasonwhythewordbelatedwasinvented.“Happybelatedbirthday!”isshortfor:“Well,IknowIforgot,butthenIremembered.Forgivemeandhappybirthday.”Theunderlinedword“belated”inSituationⅣprobablymeans________.A.predictedB.returnedC.cancelledD.delayed[答案]D词义猜测题。由“Happybelatedbirthday!”isshortfor:“Well,IknowIforgot,butthenIremembered.Forgivemeandhappybirthday.”可以推断出。【解题法】词汇意义猜测题的解题思路(1)结合上下文,读懂语境。(2)根据逻辑关系、构词法、定语从句、同位语等来猜测画线词的意义。(3)把答案代入原文,验证上下文语句是否合乎逻辑。命题法2代词指代猜测题典例2Therearemanyplacestogoonsafari(观赏野生动物)inAfrica,butridingahorsethroughthefloodedwatersofBotswana'sOkavangoDeltamustrankasoneoftheworld'smostexcitingwildlifejourneys.Severalsafaricampsoperateasthebaseforthisadventure,providinguniqueridestwiceadaytoexploredeepintothedelta.Thecampshaveexcellenthorses,professionalguidesandlotsofsupportworkers.Theyhaveareputationforprovidingagreatridingexperience.Whatdoestheunderlinedword“They”referto?A.Floodedwaters.B.Wildlifejourneys.C.Safaricamps.D.Uniquerides.[答案]C推理判断题。根据本段的severalsafaricamps...和第二句的thecamps...可知,这里的they指的就是thecamps。【解题法】代词指代猜测题的解题思路(1)要知道代词one,it,that,they,them等用来指代上文中提到的事物,所以要从上文找。(2)有时代词与指代对象相隔较远,要认真查找。(3)有时需要对前面提到的内容进行总结,才能得出代词所指代的事物。命题法3短语或语句意义典例3Inthemid­1950s,Iwasasomewhatboredearly­adolescentmalestudentwhobelievedthatdoing_any_more_than_necessary_was_wasted_effort.Oneday,thisapproachthrewmeintoembarrassment.InMrsTotten'seighth­grademathclassatCentralAvenueSchoolinAnderson,Indiana,wewerelearningtoaddandsubtractdecimals(小数).Ourteachertypicallyassigneddailyhomework,whichwouldberecitedinclassthefollowingday.Onmostdays,ourgradeswerebasedonouroralanswerstohomeworkquestions.MrsTottenusuallywalkedupanddowntherowsofdesksrequestinganswersfromstudentafterstudentintheorderthequestionshadappearedonourhomeworksheets.Shewouldstarteitheratthefrontorthebackoftheclassroomandworktowardtheotherend.SinceIwasseatednearthemiddleofabout35students,itwaseasytofigureoutwhichquestionsImighthavetoanswer.Thisparticulartime,Ihadcompletedmyusualtwoorthreeproblemsaccordingtomycalculations.WhatIfailedtoexpectwasthatseveralstudentswereabsent,whichthrewoffmyestimate.AsMrsTottenmadeherwayfromthebeginningoftheclass,IdesperatelytriedtodeterminewhichmathproblemIwouldget.Itriedtoworkitoutbeforeshegottome,butIhadbrainfreezeandcouldn'tfunction.WhenMrsTottenreachedmydesk,sheaskedwhatanswerI'dgotforproblemNo.14.“I...Ididn'tgetanything,”Ianswered,andmyfacefeltwarm.“Correct,”shesaid.Itturnedoutthatthecorrectanswerwaszero.WhatdidIlearnthatday?First,alwaysdoallyourhomework.Second,inreallifeitisn'talwayswhatyousaybuthowyousayitthatmatters.Third,Iwouldnevermakeitasamathematician.IfIcouldchooseoneschooldaythattaughtmethemost,itwouldbethatone.WhatdoestheunderlinedpartinParagraph1indicate?A.Itiswisetovalueone'stime.B.Itisimportanttomakeaneffort.C.Itisrighttosticktoone'sbelie
