正确答案:正确A
【答案】A【解析】第一段开头即点明了文章主旨:“theonce,undisputedU.S.scientificlead…isdiminishing.”。其他三段从三个方面对此作了阐述:“scientifictrainingrelativelyunattractivetoU.S.students”,“duringthenextfewdecades,thispathlikelywillreverttowarditsmoretraditionallengthandreestablish,inahealthyway,themoretraditionalrelationship…”,“anothernewforcealsogreatlyfacilitatedglobalization”。由此可知,本文着重讨论的是科学全球化造成美国科技领先地位的下降。主旨归纳题,应明确文章的中心思想。
