Perhaps because scientists have been so intrigued by dogs’ superior senses of smell and hearing, researchers have long ______ their eyesight, assuming that they inhabit a drab, black-and-white world, devoid of color.
【正确答案】
E
【答案解析】- 方程等号：because因为，表示因果，前后句意同义重复。 - 强词和对应：根据题意，科学家痴迷于(be intrigued by)狗的嗅觉和听觉(smell and hearing)的高等能力，后面描述他们对狗的视力(eyesight)的态度。smell and hearing和eyesight换对象，因此空格和intrigued by取反，体现他们对于狗的视力“不感兴趣”，负向。study研究，covet贪求，appreciate欣赏，resent憎恨，underestimate低估。句中并未体现科学家的主观态度，选项D排除。答案选E。
