A. resolved  D. exaggerate the efficacy
B. gainsaid  E. downplay the legitimacy
C. exploited F. question the fallibility

选项

答案C,E

解析 逻辑连接词为as,表因果,因的部分与果的部分语义相同。果的部分:对环境问题进行国际监管的支持者总是在科学的不确定性(scientific uncertainty)和经济的敌视(economic hostility)中挣扎,这两种障碍。从一种政治观点上看,通常是紧密联系在一起的(closely related)。因的部分:出于经济原因对环境监管持有敌意的人经常(i)________环境挑战中隐含的大量的不确定性来(ii)________环境监督。空格(i)要填入一个动词,表示对环境管制持有敌意的人对大量的不确定性的动作。注意,这里的the considerable uncertainty(大量的不确定性)就是scientific uncertainty(科学上的不确定性)。前文说经济上的敌意和科学上的不确定性是紧密相关的,并且这二者对于环境问题的国际监管是障碍,因此后面应该是经济上的敌意“利用”科学的不确定性来“攻击”环境监管,所以空格(i)选C项exploited(利用)。空格(ii)表达对环境监督的负向动作,表示“攻击”的含义,选E项downplay the legitimacy(贬低合理性)。有同学误选F项question the fallibility。注意。fallibility表示“出错”,那么question the fallibility“质疑错误”就是正向含义,不符合句意。
