单词注释难句剖析导读诱思

全球变暖引起北极冰雪融化,这一变化给北极熊赖以生存的家园带来了极大的威胁。北极熊通常在冰原上养育幼崽,而随着冰的融化,它们待在陆地上的时间被迫加长,吃不到冰面上可以捕捉到的海豹,从而只能以当地猎人捕捉的鲸的残余物为食……这严重影响了它们的生存及繁殖。单词注释难句剖析导读诱思Duetoclimatechanges,Arcticiceisbreakingupearlierinthespring,anditsareaisdecreasing.ThisiscreatingproblemsforpolarbearsthatmaketheirhomesoffnorthernAlaskaandinHudsonBay.单词注释难句剖析导读诱思PolarbearsoffAlaskanormallyhuntandraisetheiryoungonicesheetsthatfloatontheocean.Butastheicehasmelted,thepolarbearshavebeenforcedtospendmoretimeonland.There,theyhavebeguntofrequent①beaches,feedingontheremains②ofwhalescaughtbynativehunters.Forpolarbears,thisfoodislessnutritious③thansealsthattheynormallycatchonicesheets.Theshrinkingicehasalsoforcedmorepolarbearsintotheocean.Inthepast,theyonlyhadtoswimshortdistancesbetweenicesheets.Butastheicehasshrunk,polarbearshavebeenforcedtoswimlongerandlongerdistancesintheopenocean.Thisposes④aseveredangerduringroughweather,andanincreasingnumberofdrownedpolarbearshavebeenobserved.单词注释难句剖析导读诱思InHudsonBay,theicebreaksupthreeweeksearlierinthespringnowthanitdid20yearsago.PolarbearsinHudsonBayfast⑤duringthesummer,waitingforicetoforminthefalltohunt.Everyyear,thesummergetslonger,andthebearsgetskinnier⑥.Overthepast25years,theaverageweightofthefemalebearshasdropped68kg.Thislossaffectstheirabilitytoreproduce,andalreadythenumberofbirthshasdroppedby15percent.Unlessthebearscanlearntosurvivetheseclimatechanges,thesegiantsoftheicemayonedaydisappear.单词注释难句剖析导读诱思①frequent/frI̍kwent/vt.频繁地去②remains/rI̍meInz/n.剩余物③nutritious/njʊ̍trIʃəs/adj.有营养的④pose/pəʊz/vt.造成;形成⑤fast/f
