A.makeeffortstoclonetheendangeredpandas
B.saveendangeredanimalsfromdyingout
C.collectDNAofendangeredanimalstostudy
D.transferthenuclearofoneanimaltoanother
答案解析:
答案为B。
本题为细节题。
由第二段内容可知,“诺亚方舟”项目的目的在于收集濒临灭绝的动物的卵子、胚胎、精子和DNA,并用液体氮将它们储存起来。
如果某些物种灭绝了,将会有足够的基础建设材料再造这些物种。
最后一段第二句“We'
rebothtryingtosaveanimalsthatfaceextinction.”又一次提到了这个项目的目的,即拯救濒临灭绝的物种。
故答案为B。
2.AccordingtoP
rofessorKraemer,________.
A.thelongtimelastingcloningresearchcouldbesuccessful.
B.theeggstransfersimmediatelyresultinhavingababy.
C.thelackofnucleartransfercouldbeamajorproblemtohavenewpandas.
D.ifspeciesshoulddieout,basicbuildingblockswouldhealthem.
答案为A。
本题为推理题。
由倒数第二段第
一句话“…butthelackofavailablepandaeggscouldbeamajorproblem”可知,C选项错误。
由该段第二句话“Theywillprobablyhavetodoseveralhundredtransferstoresultinonepregnancy(havingababy).”可知,B选项错误。
由该段第三句话“Ittakesalongtimeandit'
sdifficult,butthiscouldbegroundbreakingscienceifitworks.”可知,这(细胞核移植)需要很长时间,而且难度很大,但是一旦成功,便会成为开创性的科学。
言外之意就是长期的克隆研究技术或许能成功。
故A选项正确。
第二段提到“Ifcertainspeciesshouldbecomeextinct,…th
erewouldbeenoughofthebasicbuildingblockstoreintroducethespeciesinthefuture.”,而D选项“如果物种灭绝,基础建设材料将治愈他们”夸大了基础建设材料的作用,与原文不符,故错误。
3.Thebesttitleforthepassagemaybe_________.
A.China'
sSuccessinPandasCloning
B.HelpingWaystoAvoidExtinction
C.ExploringthePossibilitytoClonePandas
D.ThePracticeinNoah'
sArk
答案为C。
本文为新闻报导类文章,第一段点出了文章的中心,中国在努力克隆濒临灭绝的大熊猫,从第二段起具体介绍DuaneKraemer对中国科学家克隆大熊猫的做法的评价,并与美国科学家正在从事的“诺亚方舟”项目做了对比。
文章最后一段表达了他们对中国同行所做的工作的高度评价。
故最佳标题为C“探索克隆大熊猫的可能性”。
4.Fromthepassageweknowthat_______.
A.Kraemerandhisteamhavesucceededincloningapanda
B.scientiststrytoimplantapanda'
seggintoarabbit
C.KraemerwillworkwithChinesescientistsincloneresearches
D.abouttwothousandspeciesaretodieoutinacentury
答案为D。
由第三段第一句话“Itisestimatedthatasmanyas2,000speciesofmammals,birdsandreptileswillprobablybecomeextinctinover100years.”可知,D选项正确。
A选项明显错误;
由第四段第一句话“Thisweek,ChinesescientistssaidtheygrewanembryobyintroducingcellsfromadeadfemalepandaintotheeggcellsofaJapanesewhiterabbit.”可知,B选项错误。
由最后一段最后一句话“Thecooperationbetweenusisverymuchneeded.”可知,ProfessorKraemer是说有必要合作,而不是将会与中国科学家一起致力于克隆研究,C选项与此表达不符,故不选。
