06TASK1- 流程图

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1.基本上不会出现数据，主要是文字信息2.较零散，出现的每一个步骤和信息都要描述3.时态单一：一般现在时4.有生词，可根据图片推断词义，直接抄下来5.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6.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：a.Theprocessstartsfrom…(+名词/动名词)b.At/inthefirst/initialstage,(+句子)c.Atthebeginningofthecycle,(+句子)d.Duringtheinitialphase,(+句子)e.Thebeginningofthewholecycleismarkedby…(+名词/动名词)f.(+名词/动名词)….isthefirststepin…(+名词/动名词)表示次阶段：a.Thesecondstageis…(+名词/动名词)b.Thenextstepintheprocessis..(+名词/动名词)c.Then,(+句子)d.Inthenextstep,(+句子)e.Afterthat,(+句子)f.Inthefollowingstage,(+句子)g.Atthispoint,(+句子)表示最后阶段：a.Finally,(+句子)b.Eventually,(+句子)c.Inthefinalstep,(+句子)d.…(+名词/动名词)isthelaststepintheprocedure.e.Thefinalphaseoftheprocessisabout…(+名词/动名词)f.Enteringthefinalstage,(+句子)3.写流程图的5大注意事项1.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2.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℃.Thisprocessisfollowedbycoolingdownthefinishedbricksfor48to72hoursinacoolingchamber.P4Oncethebrickshavecooleddownandhavebecomehard,theygetpackagedanddeliveredtotheirfinaldestination,beitabuildingsiteorstorage.
