[A]creatively [B]originally [C]authentically [D]initially
本题考查通过上下文选择适当的副词的能力。空格处的副词修饰的动作是use real-estate assets in and around train stations(利用车站内部及周围的房地产)。由上下文可知,该举动是有创造性的,所以才会引起人们的关注,因此[A]项creatively“创造性地”正确。originally“最初,原先 ,新颖地”,如The apartment was decorated quite originally(这套公寓装饰的十分别致);authentically“确实地,真正地,逼真地”,其形容词形式为authentic,如 DiMaggio was an authentic folk hero(迪马乔是一位真正的民间英雄);initially“最初,开头”,如His response was initially adamant(他的反应开始很强硬)。
