解析：對應“Bycontrast,Venusisverydryanditsthickatmosphereismostlycarbondioxide”，金比地球，水少而大氣二氧化碳含量高。C選項正確。A選項錯atmospheresofbothVenusandEarthwerederivedatleastinpartfromgasesspewedforth,oroutgassed,byvolcanoes.”；D選項文中沒有提到。正確答案:和地球上可能釋放出基本相同數量的水蒸氣：“VenusandEartharesimilarinsizeandmass,soVenusianvolcanoesmaywellhaveoutgassedasmuchwatervaporasonEarth,andbothnetswouldhavehadaboutthesamenumberofcometsstriketheir的是溫度問題，關于earlysun的一個屬性，是和溫度有關的，就是光照。大氣中，而是海洋、巖石的含碳化合物中，將句子簡化一下，就是：TheanswertothefirstquestionisthatcarbondioxideisstillfoundinabundanceonEarth，eitherdissolvedintheoceansorchemicallyboundintocarbonaterocks.C選項轉述正確。問題是……；B選項“ismoreoftenfound”無中生有；第四項“usedup”錯誤。解析：對應“Justasonpresent-dayEarth,theoceansofVenuslimitedtheamountofatmosphericcarbondioxidebydissolvingitintheoceansandbindingitupin解析這句話的大意是金星海洋的導致海洋溶解二氧化碳的機制也了。這里的“mechanism”意為“機制”“方法”，與A選項含義相符。其余選項的意思分別是“重要性”“需求”和“好處”6題也涉及到了，既然海洋了，所以從大氣層消除二氧化碳的mechanism也一樣，對應選項，只能選擇A了。解析：第五段介紹，的能量輸出漸漸加大，地表溫度高于374°C，此時“nomatterwhattheatmosphericpressure.Venusoceanswouldhavebeguntoevaporate”，直接對應C選項。解析：對應“Temperatureseventuallybecamehighenoughto"bakeout”anycarbondioxidethatwastrappedincarbonaterocks”，B選項正確。解析總結全文提到的論點金星與地球最本質的區(qū)別就在于距離遠近不同，很不一樣。ButbeingclosertotheSunthanEarthis,enoughoftheliquidwateronVenuswouldhavevaporizedtocreateathickcoverofwatervaporclouds.在第四段中說到這一點，B的根本原因也是因為D，簡言之，BD的現象之一。（D：解析入文本的意思是：這種遵循溫室氣體增加而升溫的循環(huán)就是我們所知道的runawaygreenhouseeffect；前方應該要提到溫度上升帶來溫室氣體的這一正：Early AC；Present-day BF解析：A選項對應第二段“VenusianvolcanoesmaywellhaveoutgassedasmuchwatervaporasonEarth”“Infact,waterprobablyoncedominatedtheVenusianatmosphere.”；C選項對應第一段“TheoriginalatmospheresofbothVenusandEarthwerederivedatleastinpartfromgasesspewedforth,oroutgassed,byvolcanoes.”。B選項對應第六段“outgassedcarbondioxidebegantoaccumulateintheatmosphere”；F選項對應第六段“solarultravioletradiationhavingbrokendownatmosphericwater
