第五讲如何写拓展句文章的一个段落通常包括主题句和拓展句两部分(有的还有结尾句)。其中，主题句一般位于段首，提出段落主题、确定段落发展方向及展开模式，而拓展句则用以阐述、论证、支持主题句的要点，使段落更加丰满。一般来说，围绕主题句展开拓展句的模式有以下几种：一、解释原因例如：在大城市工作有什么好处。Workinginabigcityisofcourseanexcitingthing,whichmeansbetteropportunitiesandmoreconveniences.It’seasiertofindawellpaidjoborabetterplatformtoimproveoneself.二、列举支撑点例如：我们如何做才能节省能源。Ifwewanttosaveenergythenweneedtochangethewaywebehave.Ontheonehand,weneedtobuyappliancesthataremoreenergyefficientandlimittheamountoftimeweusethem.Ontheotherhand,toreducetheeffectthegreenhousegaseshaveonouratmosphere,weshouldplantmoretrees.三、举例例如：成长环境对学生的影响。Sincestudentsarebroughtupindifferentenvironments,theywillhavedifferenthabitsandcharacters,whichwillcausemanyconflictsindailylife.Insuchcases,theseyoungsterswilloftenactimpulsively,quarrelingorevenfightingwithhisorherclassmatesbecauseofsometrivialthings.Theymaycurseeachotherwithhatredwordsorasktheirfriendstoisolatethesestudents.What’sworse,theymayfindsomeexcusestohurt,beatorevenbullythosewhohaveconflictswiththem.四、比较和对比例如：是不是越快越好？Isitthefasterthebetter?Manypeoplebelievethatthefasterthebetter,becausetheycansavetimeinthisway.However,othersincludingmeholdtheopinionthat,inmanysituations,theresultisfarlessthanbeingsatisfactoryandquiteoftengoestotheopposites.Hastemakeswaste.五、细化主题句例如：你所喜欢的体育项目对你的影响。AsfarasI’mconcerned,I’mfondofjoggingwhichisveryessentialinmylife.Ononehand,it’snotaroughsportandconvenienttodoeveryday,fromwhichIrelaxmyselfalotandrefreshmymind.Ontheotherhand,itstrengthensmysuppleness,enduranceandperseverancetodealwiththedifficultiesinmystudy.六、引出经历例如：讲述你(或你朋友)因为太多干扰而受到影响的经历。ThisremindsmeofwhathappenedwhenIenteredhighschoolasaSeniorOnestudent.Iwassoexcitedtofindthattherewerevariousstudentorganizationsandafterclassactivitiesforusstudents.Itseemedthatmanygroupsweresuitableforme.Duringthisterm,IwasattractedwhenevertherewasanoticefromastudentgroupandIwaseagertofindoutmoreaboutit.Asaresult,Ididn’tspendenoughtimeonmystudies,norcouldIsettledowntomyhomeworkeveryday.Consequently,Ifailedinanimportantexam.七、说明结果例如：你对国家“禁止商场免费提供塑料袋的看法”。Itisnecessaryforthegovernmenttoforbidshopsfromofferingfreeplasticbags.Withthisban,shoppingcustomerswouldgraduallyformahabitofbringingenvironmentallyfriendlybagswiththemsothattheconsumptionofplasticbagswouldbegreatlyreduced.根据所给主题句写出相应的拓展句1．Fromtheviewpointofamiddleschoolstudent,Ithinkitvitaltofightforourfreedom.Sinceeveryoneisbornequal,wearesupposedtoenjoyourpersonalrightsandliveaswelike.Asfreedomisfundamentaltoone’shappiness,weshouldsparenoeffortstopursuethisGodgivenpresent.2．Asstudents,wehavetheresponsibilitytolivealowcarbonlifeforthepurposeofreducinggreenhousegases.Firstly,you’reyourclothesbyhandsinsteadofusingwashingmachines.Secondly,don’ttakeelevatorsunlessitisnecessary,forusingstairsdoesgoodtoyou’reyourhealthandtheenvironment.Thirdly,remembertobringyourownshoppingbagswhenyougotothesupermarketandgotoschoolonfootorbybicycle.3．Itotallyagreewiththeauthorthatgettingupearlyinthemorningisagoodhabitthatwillbenefitusalot.Justlikemanyofmyfriends,I’manearlybird.Ibenefitalotfromthehabitofgettingupearly.Aftergettingupearlyinthemorning,Ihaveenoughtimetomakeaplanfortheworkofthedayanddoitmoreeffectively.Ifgettinguptoolate,Iwillfeelgreatpressureandusuallycan’tfinishmyworkontime.4．Icameacrossmanysetbacksinmystudyandlife.Forexample,IfailedinmymathfinalexamwhenIwasinSeniorOne.Knowingtheresult,Icriedhard.Ianalyzedthesituationandstudiedharder.Withallmyeffortsandthehelpofothers,Ifinallybecamegoodatmathandpassedmanyexams.5．Reasonsfortheproblemsofbuyingticketsonlinearedivided.Ononehand,forpeasantworkers,lackingtheknowledgeofcomputershasgotthemintotrouble.Ontheotherhand,theticketsellingsystemisnotadvancedenoughtodealwithdifferentsituations.THANKS!>>谢谢观看
