假设你同一个男人或女人性交：·要使用避孕套。它可以防止性交时产生的液体的传入。ThefollowingstatementsareNOTtrue.·ApersoncannotgetHIVthefirsttimetheyhavesexeq\o(○,\s\up1(21)).WRONG.IfonesexualpartnerhasHIV,theotherpartnercouldbeeinfected.·Youcantelleq\o(○,\s\up1(22))bylookingatsomeonewhetherornottheyhaveHIVeq\o(○,\s\up1(23)).WRONG.ManypeoplecarryingHIVeq\o(○,\s\up1(24))lookperfectlyhealthy.ItisonlywhenthediseasehasprogressedtoAIDSthatapersonbeginstolooksickeq\o(○,\s\up1(25)).·Onlyhomosexualseq\o(○,\s\up1(26))getAIDS.WRONG.AnyonewhohassexwithapersoninfectedwithHIV/AIDSeq\o(○,\s\up1(27))risksgettingthevirus.Womenareslightlymorelikelytoeq\o(○,\s\up1(28))beeinfectedthanmen.eq\o(○,\s\up1(21))thefirsttime意为“第一次……的时候〞，引导时间状语从句。eq\o(○,\s\up1(22))tell此处表示“推断；区分〞。eq\o(○,\s\up1(23))whetherornot...是宾语从句。eq\o(○,\s\up1(24))现在分词短语作定语，修饰manypeople。eq\o(○,\s\up1(25))此为强调句型，被强调局部为时间状语从句onlywhen...。eq\o(○,\s\up1(26))homosexual/ˌhəʊmə'sekʃʊəl/n.同性恋adj.同性恋的eq\o(○,\s\up1(27))who引导定语从句修饰anyone，从句中过去分词短语infectedwith...作aperson的后置定语。其中anyonewho...＝whoever...。eq\o(○,\s\up1(28))belikelytodo可能做以下这些说法都是错误的。·初次性交的人不行能染上HIV病毒。错了。假设性交的一方有HIV病毒，另一方就有可能被传染上。·通过观看你可以看出某人是否带有HIV病毒。错了。很多HIV病毒携带者看上去特别健康。只有当这种病毒开展成艾滋病时，人才会显出病态。·只有同性恋才得艾滋病。错了。任何人假设同感染了HIV病毒/艾滋病的人性交都有染上这种病毒的危急。女性感染病毒的可能性比男性略微大一些。·Ifyouhug,touchorkisssomeonewithAIDSorvisitthemintheirhome,youwillgetHIV/AIDSeq\o(○,\s\up1(29)).WRONG.Youcanonlygetthediseasefrombloodorsexualfluid.Unfortunately,peoplewithHIVsometimeslosetheirfriendsbecauseofprejudiceeq\o(○,\s\up1(30)).ManypeopleareafraidthattheywillgetHIV/AIDSfromthoseinfectedwithHIV/AIDS.Forthesamereason,someAIDSpatientscannotfindanyonetolookafterthemwhentheyaresickeq\o(○,\s\up1(31)).·YoucangetHIV/AIDSfrommosquitoes.WRONG.Thereisnoevidenceeq\o(○,\s\up1(32))ofthis.eq\o(○,\s\up1(29))Ifyouhug...,youwillget...,if引导条件状语从句，在含有条件状语从句的主从复合句中，假设主句为一般将来时，从句常用一般现在时表示将来。eq\o(○,\s\up1(30))prejudice/'predʒʊdIs/n.偏见；成见eq\o(○,\s\up1(31))不定式短语tolookafterthem作目的状语；when引导时间状语从句。eq\o(○,\s\up1(32))evidencen．证据evidentadj.明显的·假设你同艾滋病患者拥抱、接触或亲吻，或者去他们家做客，你就会从他们那里感染上HIV病毒或得艾滋病。错了。你只可能通过血液或性交时的液体传染上这种病。不幸的是，由于偏见，HIV病毒携带者有时会失去他们的伴侣。很多人担忧他们会从HIV病毒携带者或艾滋病患者那儿染上HIV病毒或感染上艾滋病。由于相同的理由，有些艾滋病患者在生病时找不到任何人来照看他们。·蚊子可以传染HIV病毒和艾滋病。错了。目前还没有证据说明这一点。Step1Readthetextandanswerthefollowingquestions.1．Scanthetextandchoosethemainideaforeachpart.Part1A．Waystoprotectyourself.Part2B．SomewrongstatementsaboutAIDS.Part3C．BackgroundinformationaboutHIV/AIDS.答案：Part1—C,Part2—A,Part3—B2．Thepassagetellsusabout.A．somemonunderstandingofHIV/AIDSB．scientistshavefoundacureforHIV/AIDSC．waystoprotectourselvesD．thedefinitionofHIV/AIDSandthewarningtous答案：DStep2Choosethebestanswersaccordingtothetext.1．YoucangetHIVthrough.A．havingmealswiththepatientswithAIDSB．kissingsomeonewithAIDSC．injectingdrugsusingthesameneedleD．touchingsomeoneinfectedwithHIV2．Wecaninferfromthepassagethat.A．HIVisthesameasAIDSB．HIVisdifferentfromAIDSC．HIVweakensaperson'simmunesystemD．youcanhaveHIVinyourbloodforquitealongtime3．Inordertostaysafe,you.A．shouldnotusetheneedlesomeoneelsehasusedB．havetoavoidusinganythingelsethatthepersonhasusedwhileinjectingdrugsC．shoulduseacondomifyouhavesexwithanotherpersonD．alloftheabove4．Thepassageisa(n).A．advertisement
