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。
