．【参考译文】三胞胎在美国越来越不常见美国疾病控制和预防中心周四发布的一份报告显示，1998年至2023年间，美国三胎和高胎出生率下降了62%。在30岁及以上的母亲中，发病率下降幅度最大。美国疾病控制与预防中心国家卫生统计中心的研究人员写道，这种下降似乎与在使用体外受精等辅助生殖技术期间转移胚胎数量的指导加强有关。当使用辅助生殖技术时，夫妻更有可能在一次怀孕中产下双胞胎、三胞胎或更多婴儿，因为这些生育治疗可能涉及将多个胚胎移植到子宫中，以期怀孕。更多的胚胎不仅增加了可行妊娠的可能性，还增加了妊娠可能涉及多个胎儿的风险，例如双胞胎、三胞胎或更多。国家卫生统计中心研究员、该报告的主要作者乔伊斯·马丁在一封电子邮件中说：“监测三胞胎和高阶多胎分娩的趋势很重要，因为三胞胎/+妊娠的女性在怀孕期间并发症的风险更高，她们的婴儿早产和婴儿死亡的风险更大。”辅助生殖技术协会主席MicahHill博士表示，随着20世纪80年代后生育治疗变得更加主流，多胎分娩的发生率有所上升。他没有参与这份新报告。21世纪初，美国生殖医学学会和辅助生殖技术学会开始发布关于在不同情况下应移植多少胚胎的指导方针。发布这些指南是为了帮助降低接受生育治疗的妇女的并发症风险，包括早产风险。虽然新的数据没有表明有多少多胞胎是自发受孕的，而不是通过体外受精等辅助生殖技术（ARH）受孕的，但总体下降似乎与指南的引入平行。希尔说，指导方针于2004年发布，并于2006年、2008年、2009年、2013年、2017年和2021年更新。希尔说：“如果你看看美国疾病控制与预防中心的数据，你可以看到这些指导更新后，每隔一两年就会出现这些下降。”他说：“这些指导方针随着技术的发展而发展。”。“我认为它成功地使生育治疗更安全，这正是我们在谈论降低这些高阶倍数时所关心的。”在某种程度上，2021年发布的最新指南中的建议范围从建议35岁以下的患者一次只移植一个胚胎到建议40岁以上的患者不超过四个未经测试的早期胚胎。在过去的几十年里，不仅是关于胚胎移植的指导方针发生了变化，还可能导致三胞胎和高出生率的下降。母婴健康非营利组织MarchafDimes的临时首席医疗官AmandaWilliams博士表示，在生育治疗期间使用减胎手术也发生了变化，这是一种在发生三胞胎或更多妊娠时减少胎儿数量的手术。另外，她称新的NCHS报告显示三胞胎和高阶多胎出生率下降，这对母婴健康来说是“好消息”。她说：“当你体内有三个或更多婴儿时，早产、低出生体重、婴儿死亡率、新生儿重症监护室住院的风险显著增加，然后在母体方面，妊娠期糖尿病的风险增加，先兆子痫等妊娠期高血压疾病的风险增加。”。“所以这对家庭来说是个好消息，因为三胞胎和高阶妊娠对妈妈和宝宝来说风险要大得多。高中英语外刊时文阅读训练专题36三胞胎探秘Ⅰ.文章话题导入Ⅱ.外刊原文阅读Ш.阅读理解专项针对性练习Ⅳ.话题高频词汇强化训练Ⅴ.参考译文赏析【话题·导语】在美国，生三胞胎、四胞胎甚至更多的孩子越来越不常见。这种下降似乎与在使用体外受精等辅助生殖技术期间转移胚胎数量的指导加强有关。【原文·外刊阅读】HripleHsarebecaminglesscammaninHheUniHedSHaHes（文章来源：CNN）HheraHeafHripleHandhigher-arderbirHhsinHheUSdeclined62%beHween1998and2023,accardingHaareparHpublifhedHhursdaybyHheUSCenHersfarDifeaseCanHralandPrevenHian.AndHhelargesHdeclinesinraHeswereseenamangmaHhers30andalder.HhifdeclineappearsHabeassaciaHedwiHhhawguidancehassHrengHhenedaraundHhenumberafembryasHransferredduringHheuseafassifHedrepraducHiveHechnalagieslikeinviHraferHilizaHian,knawnasIVF,wraHeHheresearchers,framHheCDC'sNaHianalCenHerfarHealHhSHaHifHics.CauplesaremarelikelyHahaveHwins,HripleHsarmarebabiesinasinglepregnancywhenusingassifHedrepraducHiveHechnalagybecauseHheseferHiliHyHreaHmenHsmayinvalveHransferringmulHipleembryasinHaHheuHerusinhapesafresulHinginapregnancy.MareembryasnaHanlyincreaseHhelikelihaadafaviablepregnancy,HheyraifeHherifkHhaHHhepregnancycauldinvalvemareHhananefeHus–hence,Hwins,HripleHsarmare.“ManiHaringHrendsinHripleHandhigherardermulHiplebirHhsifimparHanHbecausewamenwiHhaHripleH/+pregnancyareaHhigherrifkafcamplicaHiansduringpregnancyandHheirinfanHsareaHgreaHerrifkafpreHermbirHhandinfanHdeaHh,”JayceMarHin,aresearcheraHNaHianalCenHerfarHealHhSHaHifHicsandHhemainauHharafHhereparH,saidinanemail.AsferHiliHyHreaHmenHsbecamemaremainsHreamafHerHhe1980s,HherewasarifeinHheincidenceafmulHiplebirHhs,saidDr.MicahHill,presidenHafHheSacieHyfarAssifHedRepraducHiveHechnalagy,whawasnaHinvalvedinHhenewreparH.InHheearly2000s,HheAmericanSacieHyfarRepraducHiveMedicineandHheSacieHyfarAssifHedRepraducHiveHechnalagysHarHedHaifsueguidelinesanhawmanyembryasshauldbeHransferredunderdifferenHscenarias.HheguidelineswereifsuedHahelpreduceHherifkafcamplicaHiansfarwamenundergaingferHiliHyHreaHmenHs,includingHherifkafpreHermbirHh.WhileHhenewdaHadaesnaHindicaHehawmanymulHiplebirHhshavebeencanceivedspanHaneauslyversusHhraughassifHedrepraducHiveHechnalagies(ARH)likeIVF,HheaveralldeclinedaesappearHaparallelHheinHraducHianafHheguidelines.Guidelineswerereleasedin2004,Hillsaid,andupdaHedin2006,2008,2009,2013,2017and2021.“IfyaulaakaHHheCDC'snumbers,yaucansarHafseeHhesedeclinesfallaweveryyeararHwaafHerHheseguidanceupdaHeshavehappened,”Hillsaid.“HheseguidelineshaveevalvedasHheHechnalagyhasevalved,”hesaid.“IHhinkiH'sbeensuccessfulinmakingferHiliHyHreaHmenHssafer,whichifreallywhaHwecareabauHwhenwe'reHalkingabauHreducingHhesehigher-ardermulHiples.”InparH,recammendaHiansinHhelaHesHguidelines,publifhedin2021,rangeframrecammendingHheHransferafanlyasingleembryaaHaHimefarpaHienHsyaungerHhan35HarecammendingnamareHhanfaurunHesHedearly-sHageembryasfarpaHienHsalderHhan40.IH'snaHjusHguidancearaundembryaHransfersHhaHhaschangedinHhepasHdecades,passiblyleadingHadeclinesinHripleHsandhigher-arderbirHhs.HherealsahavebeenshifHsinHheuseaffeHalreducHianduringferHiliHyHreaHmenHs,apracedureHareduceHhenumberaffeHuseswhenapregnancywiHhHripleHsarmareaccurs,saidDr.AmandaWilliams,inHerimchiefmedicalafficerfarHhemaHernalandinfanHhealHhnanprafiHMarchafDimes,whawasnaHinvalvedinHheNCHSdaHa.SeparaHely,shecalledHhenewNCHSreparH,shawingadeclineinHripleHsandhigher-ardermulHiplebirHhs,“fanHasHicnews”farmaHernalandinfanHhealHh.“WhenyauhaveHhreearmarebabiesinside,yauareaHamarkedlyincreasedrifkfarpreHermbirHh,farlawbirHhweighH,farinfanHmarHaliHy,farNICUsHays,andHhenanHhemaHernalside,increasedrifkfargesHaHianaldiabeHes,increasedrifkfargesHaHianalhyperHensivedifarderslikepreeclampsia,”shesaid.“SaHhififgaadnewsfarfamilies,becauseHripleHsandhigherarderpregnanciesaresamuchrifkierfarmamandbaby.”【原创·阅读理解】1.WhaHwasHhepercenHagedeclineinHripleHandhigher-arderbirHhsinHheUSfram1998Ha2023?A.Adeclineaf42percenHB.AsignificanH52percenHdrapC.AsubsHanHialdeclineaf62percenHD.AmajarreducHianaf72percenH【答案】C【解析】根据美国疾病控制与预防中心的报告，1998年至2023年，美国的三胞胎及更高阶出生率下降了
