以下为本文档部分文字说明:
1高考英语阅读理解篇章结构分析技能一、科普类文章1.引出中心内容的方法(1)AbutB。这个时候B是文章的中心。为了不让文章显得太突兀,一般会先讲A,即普通的内容(科普类文章一般介绍的是我们不太熟悉的内容)。另外,A也有可能是一种欲扬先抑的写作
手法,与B的意思正好相反。Mostanimalshavelittleconnectionwithanimalsofadifferentkind,unlesstheyhuntthemforfood.Sometimes,howeve
r,twokindsofanimalscometogetherinapartnership(伙伴关系)whichdoesgoodtobothofthem.Youmayhavenoticedsomebirdssittingonthebacksofsheep.
Thisisnotbecausetheywantaride,butbecausetheyfindeasyfoodintheparasites(寄生虫)onsheep.Thesheepallowthebirdstodosobec
ausetheyremovethecauseofdiscomfort.Soalthoughtheycanmanagewithouteachother,theydobettertogether.Theideaoffighti
nganoisebymakingmorenoisesoundsstrange,butthat’sexactlywhatmotorengineersaredoinginGermanyandsomeothercountries.
(2)用熟悉的事物作类比。这是一种我们可以借鉴的写作方法。Decision-thinkingisnotunlikepoker—itoftenmattersnotonlywhatyouthink,butalsowhatothersthinkyouthinkandw
hatyouthinktheythinkyouthink.Thementalprocessissimilar.Naturally,thiscardgamehasoftenbeenofconsiderableinteresttopeoplewhoare,byanystandards,goodthi
nkers.2.说明中心内容的方法(高考文章以说明为主,在高级阅读考试中经常出现的议论文在高考中比较少见)(1)举例说明。这是最常见的方法,除了我们熟悉的forexample,forinstance,suchas以外,更主要的是在内容上的抽象程度
的不同。例子总是说得很具体,比如说有数字,具体的人物、事件等。有的时候,在事实和例子中间,还有一个具体说明的中间层次。(2)讲原理Car-maker’sresearchanddevelopmentlaboratoriesh
avealreadyprovedthatmixinginmorenoisewiththehelpofloudspeakerscanreducetheunwantednoise.(3)讲好处(advantage)Anothergoodthi
ngabouttheusesofnoise-killingsystemsisthatitsavestheneedforasilencer,whichnotonlyreducestheweightofaca

nmostcarsin1996.Butthecarmakershaven’tdecidediftheywillputitintoproductionbecauseitwouldaddseveralhundreddollarstothecostofth
eircars.(5)讲应用(application)(6)分类说明:中心的两个方面Therearetwotypesoffat:externalfat(fatunderskin)andinternal
fat(fatinsidethebodywall).Doctors,whohavebeenexaminingtherelationshipbetweenhealthandfatness,havefou
ndthatthe“pears”havelessinternalfat,butthe“apples”have2moreinternalfatthanexternalfat.Thisseemstobewhatcausesthehealthproblems.(7)强对比
说明Onemistakenideaaboutbusinessisthatitcanbetreatedasagameofperfectinformation.Quitethereverse.Business,pol
itics,lifeitselfaregameswhichwemustnormallyplaywithveryimperfectinformation.Businessdecisionsareoftenmadewithmanyunknownandunknowablefact
orswhichwouldevenpuzzlebestpokerplayers.Butfewbusinesspeoplefinditcomfortabletoadmitthattheyaretakingachance,andmanystill
prefertobelievethattheyareplayingchess,notpoker.二、社会观点类文章这一类文章比较高级,所以在高考中出现得很少。Computerpeopletalkalotabouttheneedforo
