Unit22EnvironmentalProtection趣味导引TravelingLight中文名称为《轻装前行》，是一首由JoelHanson演唱的乡村风格歌曲。这首歌曲是很轻松的音乐，思绪在缥缈的旋律中尽情地放纵，往事在悠悠的曲子里隐现，动听的旋律勾起的总是最美好的回忆。就像在夕阳下，迎着柔和的阳光，卸下身上重重的行囊，奔向远方去旅行！TravelingLightByJoelHansonWellIwasdoublingovertheloadonmyshouldersWasaweightIcarriedwithmeeverydayCrossingmilesoffrustrations①andriversaragingPickingupstonesIfoundalongthewayIstaggered②andIstumbled③downPathwaysoftroubleIwashauling④thosesouvenirs⑤ofmiseryAndwitheachsteptakenmybackwasbreakingTillIfoundtheOnewhotookitallfrommeDownbytheriverside(Downbytheriverside)IlaidmyburdensdownNowI’mtravelinglightMyspiritliftedhigh(Ifoundmyfreedomnow)IfoundmyfreedomnowAndI’mtravelinglightThroughthedarkestalleysandloneliestvalleysIwasdragging⑥thoseheavychainsofdoubtandfearThenwiththeonewordspokenthe轻装前行乔伊·汉森如双倍的重量压在肩上感觉自己每日在负重前行走过挫折的道路，穿越伤痛的河流不断俯拾寻找路旁的卵石我摇晃着，坎坷前行眼前是充满烦恼的路我拖曳着这些痛苦的负重每一步都感觉后背要被压垮直到我发现了他卸下了我全部的负重走在河滩上我卸下了负重现在我轻装前行我的精神在升腾我找到了自由我轻装前行在黑暗的隧道和孤独的山谷里我曾背负那些沉重的锁链充满不安和恐惧可现在一句简单的话语，锁链已打开他引导我来到了再也不要流泪的地方走在河滩上我卸下了负重现在我轻装前行我的精神在升腾我找到了自由我轻装前行[词海拾贝]frustration[frʌ'streIʃn]n.挫折；挫败stagger['stæɡə(r)]vi.蹒跚；动摇stumble['stʌmbl]vi.跌跌撞撞地走，蹒跚haul[hɔːl]v.拖，拉souvenir[suːvə'nIə(r)]n.纪念品；礼物drag[dræɡ]v.拖拽；吃力地往前拉lockswerebrokenNowHe’sleadingmetoplacesWheretherearenotearsDownbytheriverside(Downbytheriverside)IlaidmyburdensdownNowI’mtravelinglightMyspiritliftedhigh(Ifoundmyfreedomnow)IfoundmyfreedomnowAndI’mtravelinglightSectionⅠWarmup&Lesson1—ComprehendingCanwetaketheheat?Inthelastfewdecades①，scientistshavereachedconsensus②andreportedthathumanbeingsarecausingchangesintheEarth’sclimate—somethingpreviouslyseenasbeyondourcontrol③.Theyclaim④thatinthelast50years,gasespumpedinto⑤theEarth’satmospherebythefactoriesandvehicleshavebeenspeedingup⑥theprocessofglobalwarmingandaffectingourclimate.Lookingahead⑦，scientistsbelievethatglobalwarmingcouldbeoneofthebiggestenvironmentalproblemsfacingthe21stcentury⑧.Butwhatexactlyisglobalwarming,whyisitseenas⑨adanger,andhowisitrelevant⑩toourlives?Globalwarmingrefersto⑪anaverageincreaseintheEarth’stemperaturethat,inturn⑫，leadsto⑬climatechange.ScientistsfoundthatthetemperatureoftheEarthiscontrolledbygreenhousegasessuchascarbondioxidewhichtrapheatfromthesunintheEarth’satmosphere⑭.Withoutthesenaturallyoccurringgases,thesun’srays⑮wouldbounce⑯backintospaceleavingtheEarthcoldandimpossibletoliveon⑰.Whenthepresenceofthesegasesintheatmosphereincreases,however,moreheatistrapped⑱andtheEarth’stemperaturerises.①此处意为：在过去几十年里，与现在完成时连用。in可以换为over或during。②consensus[kən'sensəs]n．一致的意见③beyondone’scontrol超出某人的控制seenas...是过去分词短语作后置定语，修饰something。④claim[kleIm]vt.声称⑤pumpinto...注入，此处是过去分词作后置定语，修饰gases。⑥speedup加速；slowdown减速⑦lookahead展望未来，向前看⑧此处是现在分词作后置定语，修饰problems。⑨beseenas...被看作……⑩relevant['reləvntə]adj.有关的berelevantto...与……相关⑪refer[rI'fз]ːto...
