雅思作文四个bar chart

雅思作文四个barchart在雅思写作中，柱状图（BarChart）是常见的图表类型之一，要求考生根据图表中的数据进行描述和分析。以下是四个不同主题的雅思作文柱状图示例及其简要分析：示例一：交通事故统计主题：不同交通工具每1亿乘客英里（PMT）的交通事故及受伤人数统计描述：Thebarchartcomparesthenumberofincidentsandinjuriesforevery100millionpassengermilestravelledonfivedifferenttypesofpublictransportin2002.Itisclearthatthemostincidentsandinjuriestookplaceondemand-responsevehicles.Bycontrast,commuterrailservicesrecordedbyfarthelowestfigures.Atotalof225incidentsand173injuries,per100millionpassengermilestravelled,tookplaceondemand-responsetransportservices.Thesefigureswerenearlythreetimesashighasthoseforthesecondhighestcategory,busservices,whichreported76incidentsand66injuries.Railservicesexperiencedfewerproblems.Thenumberofincidentsonlightrailtrainsequalledthefigurerecordedforbuses,butthereweresignificantlyfewerinjuries,atonly39.Heavyrailservicessawlowernumbersofsucheventsthanlightrailservices,butcommuterrailpassengerswereevenlesslikelytoexperienceproblems.Infact,only20incidentsand17injuriesoccurredoncommutertrains.分析：开头部分简要介绍了图表的主题和统计年份。概述部分对比了交通事故和受伤人数最多的交通工具（按需响应车辆）和最少的交通工具（通勤铁路服务）。细节部分按交通工具类型进行了分类描述，并使用了倍数、等量等对比手法。示例二：各地房价变化主题：五个不同城市1989年至2002年间平均房价的变化描述：Thebarchartcomparesthecostofanaveragehouseinfivemajorcitiesoveraperiodof13yearsfrom1989.Wecanseethathousepricesfelloverallbetween1990and1995,butmostofthecitiessawrisingpricesbetween1996and2002.Londonexperiencedbyfarthegreatestchangesinhousepricesoverthe13-yearperiod.Overthe5yearsafter1989,thecostofaveragehomesinTokyoandLondondroppedbyaround7%,whileNewYorkhousepriceswentdownby5%.Bycontrast,pricesrosebyapproximately2%inbothMadridandFrankfurt.Between1996and2002,Londonhousepricesjumpedtoaround12%abovethe1989average.HomebuyersinNewYorkalsohadtopaysignificantlymore,withpricesrisingto5%abovethe1989average,buthomesinTokyoremainedcheaperthantheywerein1989.ThecostofanaveragehomeinMadridrosebyafurther2%,whilepricesinFrankfurtremainedstable.分析：开头部分简要介绍了图表的主题和统计时间段。概述部分描述了房价的总体变化趋势（1990-1995年下降，1996-2002年上升）以及伦敦房价变化最大。细节部分按时间段和城市进行了分类描述，并使用了百分比等数据进行对比。示例三：家用设备能耗与费用主题：16种不同家用设备的相对电力消耗和每年的费用描述：Thebarchartcomparestheenergyconsumptionandexpenseofoperating16differentitemsofhouseholdequipment.Overall,wecanseesignificantdifferencesinbothcostandconsumption.Tobeginwith,therearesomecommonhouseholditemswhichconsumerelativelylittleenergy.Theseincludeanelectricblanket(approx.
