9：雅思阅读配对题

第八讲：雅思阅读配对题一、形式：三部分组成•题目要求、选项的集合、题目的集合二、特点：难以捉摸•大多数是细节信息（段落配信息题除外）•有乱序分布三、分类•配对一方是特殊定位词•人名配观点•地点配解决措施•时间配事件乱序•配对双方是长句子•问题配答案•原因配结果正序•段落配信息•乱序---语言实力四、基本解题步骤•识别配对的双方的类型以及各自的数量•决定先定位哪一方•通读配对另一方，划出全部定位词，逐段进行配对1.配对一方是特殊定位词•方法：•A迅速浏览定位词，在文中划出，没有出现定位词的段落一律不考虑。•B通读配对题的另一方，划出定位词，逐段配对。•例题：剑一T2P1Q1-7AWhydohumans,virtuallyaloneamongallanimalspecies,displayadistinctleftorrighthandedness?Notevenourclosestrelativesamongtheapespossesssuchdecidedlateralasymmetry,aspsychologistscallit.Yetabout90percentofeveryhumanpopulationthathaseverlivedappearstohavebeenright-handed.ProfessorBryanTurneratDeaconUniversityhasstudiedtheresearchliteratureonleft-handednessandfoundthathandednessgoeswithsidedness.Sonineoutoftenpeopleareright-handedandeightareright-footed.Henotedthatthisdistinctiveasymmetryinthehumanpopulationisitselfsystematic.Humansthinkincategories:blackandwhite,upanddown,leftandright.It'sasystemofsignsthatenablesustocategoriesphenomenathatareessentiallyambiguous.BResearchhasshownthatthereisgeneticorinheritedelementtohandedness.Butwhileleft-handednesstendstoruninfamilies,neitherleftnorrighthandlerswillautomaticallyproduceoff-springwiththesamehandedness;infactabout6percentofchildrenwithtworight-handedparentswillbeleft-handed.However,amongtwoleft-handedparents,perhaps40percentofthechildrenwillalsobeleft-handed.Withonerightandoneleft-handedparent,15to20percentoftheoffspringwillbeleft-handed.Evenamongidenticaltwinswhohaveexactlythesamegenes,oneinsixpairswilldifferintheirhandedness.CWhatthenmakespeopleleft-handedifitisnotsimplygenetic?Otherfactorsmustbeatworkandresearchershaveturnedtothebrainforclues.Inthe1860stheFrenchsurgeonandanthropologist,DrPaulBoca,madetheremarkablefindingthatpatientswhohadlosttheirpowersofspeechasaresultofastroke(abloodclotinthebrain)hadparalysisoftherighthalfoftheirbody.Henotedthatsincethelefthemisphereofthebraincontrolstherighthalfofthebody,andviceversa,thebraindamagemusthavebeeninthebrain'slefthemisphere,Psychologistsnowbelievethatamongrighthandedpeople,probably95percenthavetheirlanguagecentreinthelefthemisphere,while5percenthaveright-sidedlanguage,Left-handers,however,donotshowthereversepatternbutinsteadamajorityalsoSome30percenthaverighthemispherelanguage.DDrBrinkman,abrainresearcherattheAustralianNationalUniversityinCanberra,hassuggestedthatevolutionofspeechwentwithright-handedpreference.AccordingtoBrinkman,asthebrainevolved,onesidebecamespecializedforfinecontrolofmovement(necessaryforproducingspeech)andalongwiththisevolutioncameright-handpreference.AccordingtoBrinkman,mostleft-handershavelefthemispheredominancebutalsosomecapacityintherighthemisphere.Shehasobservedthatifaleft-handedpersonisbrain-damagedinthelefthemisphere,therecoveryofspeechisquiteoftenbetterandthisisexplainedbythefactthatleft-handershaveamorebilateralspeechfunction.EInherstudiesofmacaquemonkeys,Brinkmanhasnoticedthatprimates(monkeys)seemtolearnahandpreferencefromtheirmotherinthefirstyearoflifebutthiscouldbeonehandortheother.Inhumans,however,thespecializationinfunctionofthetwohemispheresresultsinanatomicaldifferences;areasthatareinvolvedwiththeproductionofspeechareusuallylargerontheleftsidethanontheright.Sincemonkeyshavenotacquiredtheartofspeech,onewouldnotexpecttoseesuchavariationbutBrinkmanclaimstohavediscoveredatrendinmonkeystowardstheasymmetrythatisevidentinthehumanbrain.FTwoAmericanresearchers,GeschwindandGalaburda,studiedthebrainsofhumanembryosanddiscoveredthattheleft-rightasymmetryexistsbeforebirth.Butasthebraindevelops,anumberofthingscanaffectit.Everybrainisinitiallyfemaleinitsorganisationanditonlybecomesamalebrainwhenthemalefetusbeginstosecretehormones.GeschwindandGalaburdaknewthatdifferentpartsofthebrainmatureatdifferentrates;therighthemispheredevelopsfirst,thentheleft.Moreover,agirl'sbraindevelopssomewhatfasterthanthatofaboy.So,ifsomethinghappenstothebrain'sdevelopmentduringpregnancy,itismorelikelytobeaffectedinamaleandthehemispheremorelikelytobeinvolvedistheleft.Thebrainmaybecomelessliberalizedandthisinturncouldresultinleft-handednessandthedevelopmentofcertainsuperiorskillsthathavetheiroriginsinthelefthemispheresuchaslogic,rationalityandabstraction.Itshouldbenosurprisethenthatamongmathematiciansandarchitects,left-handerstendtobemorecommonandtherearemoreleft-handedmalesthanfemales.GTheresultsofthisresearchmaybesomeconsolationtoleft-handerswhohaveforcenturieslivedinaworlddesignedtosuitright-handedpeople.However,whatisalarming,accordingtoMr.CharlesMoore,awriterandjournalist,isthewaytheword`right'reinforcesitsownvirtue.Subliminallyhesays,languagetellspeopletothinkthatanythingontherightcanbetrustedwhileanythingontheleftisdangerousorevensinister.Wespeakofleft-handedcomplimentsandaccordingtoMoore,`itisnocoincidencethatleft-hand,oftendevelopastammerastheyarerobbedoftheirfreedomofspeech'.However,asmoreresearchisundertakenonthecausesoflefthandedness,attitudestowardsleft-handedpeoplearegraduallychangingforthebetter.IndeedwhenthechampiontennisplayerIndeedwhenthechampiontennisplayerIvanLendwasaskedwhatthesinglethingimprovehisgame,hesaid
