WorldAIDSDay为了保障日益增多艾滋感染者人权（humanrights），联合国世界卫生组织于1988年元月全球高峰会议（summitmeeting）中提出了“艾滋病防治方案”，并且确订每年12月1日为“世界艾滋病日”，帮助世界各国发展艾滋疫情防治策略，同步每年订定一种宣导主题，提出对艾滋人权呼吁。redribbon红丝带由来：20世纪80年代末，人们视艾滋病为一种可怕疾病。美国某些艺术家们就用红丝带来默默哀悼身边死于艾滋病同伴们。在一次世界艾滋病大会上，艾滋病病毒感染者和艾滋病病人齐声呼吁人们理解。此时，一条长长红丝带被抛在会场上空.支持者将红丝带剪成小段，并用别针将折叠好红丝带标志别在胸前。红丝带标志：象征着我们对艾滋病患者和感染者关怀与支持；象征着我们对生命热爱和对和平渴望；象征着我们要用"心"来参与预防艾滋病工作。11/25StructureAnalysisWhatisthemainideaofthepassage?AIDShasbeenaworldwideplaguesinceitfirstappearedintheUnitedStatesinthelate1970s.GovernmentshavebeenslowtointroduceprogramstohelpstopthespreadofAIDS.However,manylocalorganizationsemergedanddevelopedmanytechniquestostopthespreadofAIDS.12/25Back小结预习写作导入NHCEStructureAnalysisPartdivisionpartparagraphmainidea11~2AseriousdiseasenamedasAIDSwasdiagnosedintheU.S.A.inthelate1970s;andsincethenithasbeenabigthreattotheAmericansociety.
