TASK 流程图.ppt

流程图flowchart,(processdiagram,flowchart)要求：和图表作文一样考察频率：每年3-5次左右,1.流程图区别于图表题的特点,基本上不会出现数据，主要是文字信息较零散，出现的每一个步骤和信息都要描述时态单一：一般现在时有生词，可根据图片推断词义，直接抄下来分段灵活，流程图复杂的话，把差别不大的步骤合并在一起写要有明显的表示顺序的过渡词,2.流程图常用表示阶段和顺序的过渡词,表示首要阶段：Theprocessstartsfrom(+名词/动名词)At/inthefirst/initialstage,(+句子)Atthebeginningofthecycle,(+句子)Duringtheinitialphase,(+句子)Thebeginningofthewholecycleismarkedby(+名词/动名词)(+名词/动名词).isthefirststepin(+名词/动名词),表示次阶段：Thesecondstageis(+名词/动名词)Thenextstepintheprocessis.(+名词/动名词)Then,(+句子)Inthenextstep,(+句子)Afterthat,(+句子)Inthefollowingstage,(+句子)Atthispoint,(+句子),表示最后阶段：Finally,(+句子)Eventually,(+句子)Inthefinalstep,(+句子)(+名词/动名词)isthelaststepintheprocedure.Thefinalphaseoftheprocessisabout(+名词/动名词)Enteringthefinalstage,(+句子),3.写流程图的5大注意事项,注意读图顺序：已经标记出顺序的就按照顺序读，若没有，从最简单的开始读起充实字数：若图中步骤较少较简单，字数难到要求，那就注意各个阶段之间的比较,3.一般现在时态4.被动语态5.一般用第三人称,例：剑6,原题：ThediagramsbelowshowthelifecycleofthesilkwormandthestagesintheproductionofsilkclothSummarisetheinformationbyselectionandreportingthemailfeatures,andmakecomparisonsthererelevant.,总体：整个过程4个步骤娥产卵变幼虫吐丝变蚕茧蚕茧变娥,思路：(第一副图)1.找出已经给出的单词的词性E.G,eggs,silkwormlarva,silkthread,cocoon,moth2.根据已知单词提炼谓语动词1）产卵：lay/create/produceeggs2）(幼虫)有卵变幼虫Transfer/changesilkworm3)吐丝：SPIN/Create/producesilk4)形成蚕茧:finish/complete/archiveacocoonthreadarounditself5）变成虫：turn，然后escapefrom.Lifecycleofsilkwormbeginsagain.,3.时间段的描写，连贯性作为时间短语，独立成句表示时间的句型：Ittakes+时间+todo4.造句：主语+谓语。连词成句,Thefirstdiagramshowsthattherearefourmainstagesinthelifeofthesilkworm.Firstofall,eggsareproducedbythemothandittakestendaysforeacheggtobecomeasilkwormlarvathatfeedsonmulberryleaves.Thisstagelastsforuptosixweeksuntilthelavaproducesacocoonofsilkthreadarounditself.Afteraperiodofaboutthreeweeks,theadultmothseventuallyemergefromthesecocoonsandthelifecyclebeginsagain.,Thecocoonaretherawmaterialusedfortheproductionofsilkcloth.Onceselectedtheyareboiledinwaterandthethreadscanbeseparatedintheunwindingstage.Eachthreadisbetween300and900meterslong,Whichmeanstheycanbetwistedtogether,dyedandthenusedtoproduceclothintheweavingstage.Overall,thediagramsshowthatthecocoonstageofthesilkwormcanbeusetoproducesilkcloththroughaverysimpleprocess.,随堂练习Youshouldspendabout20minutesonthistask.Thediagrambelowshowstheprocessbywhichbricksaremanufacturedforthebuildingindustry.Summarisetheinformationbyselectingandreportingthemainfeatures,andmakecomparisonswhererelevant.Writeatleast150words.,P1,Theprocessbywhichbricksaremanufacturedforthebuildingindustrycanbeoutlinedinsevenconsecutivesteps.Firsttherawmaterial,clay,whichwasjustbelowthesurfaceofsoilincertainclay-richareashastobedugupbyadigger.,P2,Thenthelumpsofclayareplacedonametalgridinordertobreakupthebigchunksofclayintomuchsmallerareas,whichfallthroughthemetalgridontoaroller,whosemotionfurthersegregatesthebitsofclay.Sandandwaterareaddedtomakeahomogenousmixture,whichistheneitherformedinmouldsorcutintobrick-shapedpiecesbymeansofawirecutter.,P3,Thosefreshbricksarethenkeptinadryingovenforatleast24andamaximumof48hours.Thedriedbricksarethentransferredtoaso-calledkiln,anothertypeofhightemperatureoven.Firsttheyarekeptatamoderatetemperatureof200-1300.Thisprocessisfollowedbycoolingdownthefinishedbr
