中的位置和表示法：1主题句写在段落的开端，后面的支持句为主题句提供论证和细节，初学者以使用此法为宜。如：,Americansmakenodistinctioningreetingfriends，acquaintances，elders，orsuperiors.WhenAmericansseesomeonetheyknowonlybysight，theyarelikelytosay“Hi”inallcases.Thisdoesnotmeanthattheyhavenomoreregardforfriendsthanforcasualacquaintances.Itonlymeansthat“Hi”servesasgreetingforboth.2主题句写在段落末尾，前面都是提供细节的支持句，内容逐渐收拢，最后用一句总结性的主题句加以概括。如：AmericansmightbeembarrassedbecausetheirJapanesefriendsaresoformalwiththem.JapanesemightfeelinsultedbecauseAmericanacquaintancesgreetthemcasually.Still，theformsofgreetinginbothcountriesonlyshowrespectforothers.,ItjusthappensthatAmericansandJapanesehaveadifferentwayoflookingathumanrelationshipsandthushaveadifferentwayofshowingrespect.3主题句写在段落的开端和写在末尾。主题句先在段首出现，在段末又重复一遍。这种在首尾两处出现主题句的写法，具有强调或突出中心思想的作用。如：Goodmannersareimportantinallcountries，butwaysofexpressinggoodmannersaredifferentformcountrytocountry.Americanseatwithknivesandforks；Japaneseeatwithchopsticks.,Americanssay“Hi”whentheymeet；Japanesebow.ManyAmericanmenopendoorsforwomen；Japanesemendonot.Onthesurface，itappearsthatgoodmannersinAmericaarenotgoodmannersinJapan，andinawaythisistrue.Butinanycountry，theonlymannersthatareimportantarethoseinvolvingonepersonsbehaviortowardanotherperson.Inallcountriesitisgoodmannerstobehaveconsideratelytowardothersandbadmannersnotto.Itisonlythewayofbehavingthatdiffersfromcountrytocountry.4主题句写在段落中间或其它地方。此时，要根据上下文的意思才能确定该段落中体现中心思想的句子。如：,CaliforniansandNewEnglandersarebothAmerican.Theyspeakthesamelanguageandabidebythesamefederallaws.Buttheyareverydifferentintheirwaysoflife.MobilitybothphysicalandpsychologicalhasmadeagreatimpressiononthecultureofCalifornians；lackofmobilityisthemarkofthecustomsandmoralityofNewEnglanders.,活学活用划出下列段落的主题句,A,LastMonday,ourclassheldamonitorelection.Thiswasourfirstelection,soeveryonewasexcited.Twoofmyclassmatestookpartintherace；LiuDongandWangHong.Theyeachgaveaspeechtellinguswhattheywoulddowhentheywereelected.Thenwevotedforthemonitor.Theresultwas28to15inWangHongsfavor.WangHongbecameournewmonitor.Thewholeclasscheeredforher,andshepromisedtodothebestshecouldforusall.,B,InthefirstcenturyB.C.theChinesewerealreadyusingsailstomaketheirboatsgo.SailsdidnotcometoEuropeuntilnineteencenturieslater.ThekiteandamachinetoseparatewheatintopartsarrivedinEuropefourteencenturiesaftertheirinventionanduseinChina.L
