Unit3ProtectingourselvesReadingAidstodayAnewsreportfromthe18thWorldAidsDay•人类关于艾滋病的确切记载大都始于1981年。在此之前，我们对这种疾病一无所知。我们不知道在20世纪的70年代，或者更遥远的过去，有多少人感染了艾滋病，也不知道它究竟起源于何处。艾滋病从一开始就被笼罩在重重迷雾之中。虽然众说纷纭，其中不乏合理的猜测和颇有科学依据的推论，但还没有哪一种观点能够得到世人的公认。1981年，美国率先发现了艾滋病。四年后，艾滋病登陆中国。•中国的一些艾滋病监测人员起初的习惯是，哪一个地区出现艾滋病感染者，就在地图上那一部分打上红点；2000年，这项工作停止了：中国地图上已经没有被艾滋病遗漏的省份。目前，全球约有4000万艾滋病病毒携带者，其中250万为不足15岁的少年。非洲是艾滋病蔓延最严重的大陆，迄今共有2660万艾滋病病毒感染者，320万艾滋病患者，死亡230万人。Whatdothesepictureshaveincommon?Fast-readingforgeneralidea.1.WhatisthisTVnewsspecialabout?ItgivessomedetailedinformationaboutaidsandhowtofightthespreadofAids.2.HowmanypeoplearoundtheworldareinfectedwithHIVeveryday?About14,000people.3.WhatplaceshavebeenaffectedbyAids?AlmosteverycountryintheworldhasbeenaffectedbyAids.Detailedreadingforimportantinformation(1)WhatdoesAidsstandfor?Aidsstandforacquiredimmunedeficiencysyndrome.(2)HowmanychildrenhavebeenaffectedbyAidssofar?About18millionchildrenhavebeenaffectedbyAids,amongwhommorethan4millionhavebeenkilledbyAidsandmorethan14millionhavelosttheirparentstoAids.(3)HowdoesHIVaffectthebody?HIVisavirusthatentersaperson’sbloodandattacksthebody’simmunesystem,sotheimmunesystemisweakened,andthemitgraduallylosestheabilitytofightillnesses.Eventuallythebody’simmunesystembecomessoweakthatthepersonbecomessickveryeasily.(4)WhatarethethreewaysAidsistransmitted?Thethreewaysareunprotectedsex,blood-to-bloodcontactandmother-to-childtransmission.(5)WhatisbeingdoneinChinatohelpcontroltheAidsepidemic?Chinaisworkinghardtocontroltheepidemic,andhasopenedHIV/Aidslabstotestandmonitorthediseaseacrossthecountry.In2003,thegovernmentstartedprovidingfreeAidsdrugsforAidspatientsinneed.(6)WhatistheaimofUNAIDS?TheaimofUNAIDSistohelppreventthespreadofAids.(7)WhatdoesUNAIDSsoforpeoplewhothinktheymighthavethevirus?ItprovidesinfectedpeoplewithhelpfromdoctorsandtestingforpeoplewhothinktheymighthaveHIVorAids.(8)WhydidAjaninotcatchthevirusfromhismother?BecausehismotherhadaccesstoprescriptionAidsmedicationsduringpregnancy.AnswerstoC2:1g2e3a4f5b6d7cReadingstrategyFirst,let’sreadthereadingstrategyonpage35.Nowlistentotherecordingofthepassage,paragraphbyparagraph,and,whilelistening,topayattentiontothelastsentenceofeachparagraphandthefirstsentenceofthenextparagraph.Trytofindouthowaparagraphislinkedwiththenextone.AnswerstoPartD:1b2e3h4a5f6c7g8dAnswerstoPartE:1epidemic2immunesystem3cure4serious5Africa6Argentina7monitor8prescription9efforts10prevention1.What’stheserioussituationofAidsinChina?WhyaretheresomanyAidspatientsinChina?2.Whathasbeendonetodealwiththesituationbygovernmentsandinternationalorganization?3.WhatshouldbedoneandcanbedonetotreattheAidspatientsorHIVcarriers?1.Unprotectedsexisthemostcommonwaythatthevirusisspread,accountingfor75percentofadultinfectionsworldwide.(Page34)commonadjectivethesameinalotofplacesorforalotofpeople:•Eg.It'squitecommontoseecoupleswhodressalike.Thesurname'Smith'isverycommoninBritain.•accountforsth.phrasalverb,toformthetotalofsomething:Studentsaccountforthevastmajorityofourcustomers.2.Althoughmanypeoplearefamili...
