或許克隆滅亡動物存在眾多的可能性，但是即使克隆勝利了，或許會由于其賴以生存的食物鏈已經(jīng)被破壞而無法接著存活下去。由此推斷D項正確。Ⅱ.讀后續(xù)寫閱讀下面材料，依據(jù)其內(nèi)容和所給段落開頭語續(xù)寫兩段，使之構成一篇完整的短文。續(xù)寫的詞數(shù)應為150左右。IwillsharethekindactthatImetwithallofyou.Wehaddozensofrestaurantoptionswithinashortdistance,soweoftentookadvantageofthisluxury.Ononeoccasion,Iranouttogetsomefood.IsawthecloudsinthedistanceanddecidedIcouldmakeitthereandcomebackintime,butIwaswrong.Iwasabouttoleavetherestaurantwhentherainjustpoured.Thestreetwasfloodedwithinminutes.ButIhadmylittlegirlandhusbandwaitingformebackathome,andtheywerehungry,soIknewIhadtomakearunforit.Theowneroftherestauranttriedtoencouragemetowaitinside,butIinsistedthatIshouldgo.Atthispoint,hegrabbedhisumbrellaandsaid,“Okay,let'sgo.”O(jiān)fcourseItriedtoconvincehimthatitwasn'tnecessaryforhimtowalkmehome,butIknewIwouldn'tpreventhimfromdoingso.Sooffwewent.Wequicklyrealizedthattheumbrellawouldn'thelpmuchinkeepingusdry.Hewalkedmeallthewaytomyapartmentbuilding,wherehesaidgoodbyeandranbacktotherestaurant.AgainIencounteredthisactofkindnesswhenIwasmakingmywaytothebus.AsIwaitedatthecrosswalk,itbegantorainlightly.Nothingwastoobad,butayoungguynearbyfeltlikeitwasheavyenoughtomakehimstepnexttomeandholdhisumbrellaabovebothofus.Afterawhile,thelightsturnedgreen.Ithankedhimandwalkedacrossthestreet.Gettingaroundthecitywhenyouaresixmonthspregnantandhaveatwo-year-oldkidcanbechallengingsometimes.Onespringafternoon,IrealizedIneededsomethingfromthestore
