雅思阅读根据定义进行生词猜测.docx

雅思阅读根据定义进行生词猜测雅思阅读根据定义进行生词猜测1.根据定义猜测词义如果生词是句子或段落所解释的定义，理解句子或段落本身就是推断词义。例如：anthropologyisthescientificstudyofman.由定义可知，anthropology就是“研究人类的科学”。Inslangtheterm"jam"constitutesastateofbeinginwhichapersonfindshimselforherselfinadifficultsituation.同样，从上下文的定义可知jam一词在俚语中的意思是“困境”。定义句的谓语动词多为：be,mean,dealwith,beconsidered,tobe,referto,becalled,beknownas,define,represent,signify,constitute等。2.根据复述猜测词义虽然复述不如定义那样严谨、详细，但是提供的信息足以使阅读者猜出生词词义。复述部分可以适当词、短语或是从句。同位语Semantics,thestudyofthemeaningofwords,isnecessaryifyouaretospeakandreadintelligently.此例逗号中短语意为“对词意义进行研究的学科”。该短语与前面生词semanties式同位关系，因此我们不难猜出semanties指“语义学”。在复述中构成同位关系的两部分之间多用逗号连接，有时也使用破折号，冒号，分号，引号，和括号等。Capacitance,ortheabilitytostoreelectriccharge,isoneofthemostcommoncharacteristicsofelectroniccircuits.由同位语我们很快猜出生词capacitance词义---电容量。需要注意的是：同位语前还常有or,similarly,thatistosay,inotherwords,namely,orother,sayi.e.等副词或短语出现。定语从句KrabacbersuffersfromSAD,whichisshortforseasonalaffectivedisorder,asyndromecharacterizedbysevereseasonalmoodswings.根据生词SAD后面定语从句whichisshortforseasonalaffectivedisorder和同位语asyndromecharacterizedbysevereseasonalmoodswings,我们可以推断出SAD含义，即“季节性情绪紊乱症”。3.根据举例猜测词义恰当的举例能够提供猜测生词的重要线索，例如：Theconsequencesofepochaleventssuchaswarsandgreatscientificdiscoveriesarenotconfinedtoasmallgeographicalareaastheywereinthepast.句中“战争”和“重大科学发现”是生词的实例，通过它们我们可以猜出epochal的大致词义“重要的”，这与其确切含义“划时代的”十分接近。雅思阅读材料之浮法玻璃阅读段落Theprincipleoffloatglassisunchangedsincethe1950s.However,theproducthaschangeddramatically,fromasinglethicknessof6.8mmtoarangefromsub-millimeterto25mm,fromaribbonfrequentlymarredbyinclusionsandbubblestoalmostopticalperfection.Toensurethehighestquality,inspectiontakesplaceateverystage.Occasionally,abubbleisnotremovedduringrefining,asandgrainrefusestomelt,atremorinthetinputsripplesintotheglassribbon.Automatedon-lineinspectiondoestwothings.Firstly,itrevealsprocessfaultsupstreamthatcanbecorrected.Inspectiontechnologyallowsmorethan100millionmeasurementsasecondtobemadeacrosstheribbon,locatingflawstheunaidedeyewouldbeunabletosee.Secondly,itena
