24.From thepassage,wecanlearn that.A.someotherextinct specieshavebeencloned successfullyB.themammothusedtobeavery commonspeciesC.thecloneof mammothsshouldbebanned bylawD.awoollymammoth willbe successfullycloned thisyear解析选B细节理解题根据第二段最终两句Mammoths usedtobeacommonsightinNorthAmerica andEurasia.Many ofour distantancestors probablyhad regularface-to-face encounterswiththeelephant-like giants”可知,猛鸡象过去是一种非常常见的物种BAn extinctmountain goatthat wasonce commoninthePyreneesbecame thefirst animaltobebrought backfrom extinction.Researchers usedfrozen DNAto producea clone,but the newborn kiddiedwithin minutesof birthdue tobreathing difficulties.The Pyreneanibex isa typeof mountaingoat,which isoutcompletely in.Before thedeath ofthe lastknown individualbelievedto havedied(a13-year-old femaleknown asCelia),biologists tookcells fromherskin andears,which werefrozen inliquid nitrogen(氮)・An earliercloning attempttouse theskin cellsfailed.But thelatest attemptinvolved thecreation of439cloned embryos(胚胎)・Of thesecloned embryos,57were putinto thefemale domesticgoats,but onlyonegoat gavebirth andthe newborncloned kiddied afterseven minutesasaresult of lung disease.Researchers say that othercloned animals,including sheep,havebeenborn withsimilarlung disease,but theysaythatoverall theexperiment wasa majorstep forwardintheeffortto bringthe ibexback toits mountainhome.The leadingresearcher JoseFolch says,“Thecloned kidwas geneticallylikethe ibex.In speciessuch astheibex,cloning isthe onlypossibilityto avoidits completedisappearance.”The failureto producea livingclone fromDNA thatwas frozenonly fifteenyears agoshowsthe difficultyresearchers wouldface intryingtobring backspeciesthathave beenextinctfor decadesor centuries.Researchers havehad theideaofbringing backthe Tasmaniantiger,which wentextinct in
1936.There are,however,other speciesthathavebeen seriouslysuggestedfor cloning,such asthe giantpanda,the Africanbongo antelope,the Sumatrantigerand thepygmy hippo.Supporters believecloning provideshope ofkeeping theseendangeredanimals alivebefore theydie out.语篇解读科学家通过冻结的DNA成功地克隆了一只比利牛斯野生山羊这种野生山羊在就已经灭绝了
25.What dowe knowabout thecloned ibexA.It diedof lungdisease.B.It wasthefirstcloned animalintheworld.C.It livedfor thirteenyears.D.It wasbornin.解析选A细节理解题根据第二段的“thenewborncloned kiddied afterseven minutesasaresultoflungdisease”可知,这只克隆羊死于肺病
26.We canconclude fromthepassagethat・A.cloning hasdeveloped quicklyin developedcountriesB.no moreanimals willdie outinthefutureC.cloning makesit possibleto preserveendangered speciesD.cloning seldomresults inphysical problemsfor animals解析选C推理判断题根据最终一段的^Supporters believecloning provideshope ofkeepingthese endangeredanimals alivebefore theydie out”可以推断,运用克隆技术来挽救濒危动物是有但愿的
27.What sthe besttitle forthis passageA.Great advancementincloninggoatsB.Difficulties insaving extinctanimalsC.Public concernsabout cloningD.Cloning broughtback anextinct speciesforawhile解析选D主旨大意题通读全文可知,科学家们克隆了一只已经灭绝的比利牛斯野生山羊,但这只羊在出生很快就死了,故D项最适合做文章标题
28.In whichpart ofa newspaperwould youmost probablyread thispassageA.Society.B.Sports.C.Amusement.D.Science.解析选D推理判断题文章简介了克隆羊,与科学有关,故选D项CMost parentsin Britainlog ontosocial networkingsites likeFacebook tospyonwhattheir childrenare doing,a studyhas found.Figures showedthat nearly55%ofparentsthoughtof snoopiegsrouod ontheirchildrens profiles(基本信息)tosee whatthey areupto.They didit toavoid havingaawkward conversations^withthechildrenbut nearlyaquarteradmitteditwastheonly waythey couldfindout。
