问题 In 1916 Yellowstone National Park had only 25 bison, but the population has since ______to more than 2,000.

选项

答案 A,D

解析 but表示前后出现对比。前文说bison(水牛)的数量“只有25”,后文说数量“超过2000”,所以空格应体现“增长”的含义。balloon激增,mediate调停,disperse驱散,burgeon激增,reconcile调停,attenuate衰弱。答案选AD。注:这里mediate和reconcile是干扰项,同表示“调停”。burgeon这个词本意是“植物的抽条、发芽”。但在GRE考试中,不会考这个意思,因为它没有明显的同义和反义词。burgeon主要考作为引申义的“激增,迅速扩张”这一含义。
