Spanning the middle of Turkey," travelers have for centuries been captivated by the inland region known as Cappadocia,with its fantastic moonlike landscape." 引号内为划线部分～
A) travelers have for centuries been captivated by the inland region known as Cappadocia,with its fantastic moonlike landscape
B) travelers have been captivated for centuries by the inland region known as Cappadocia and by its fantastic moonlike landscape
C) the inland region known as Cappadocia has the captivated travelers for centuries with its fantastic moonlike landscape
我不明白为什么,难道不应该是travelers 才可以 span the middle of Turkey 为什么是inland region?
还有,除了这个.a 中with its fantastic moonlike landscape 和 b 中by its fantastic moonlike landscape,有什么差别,那个表达是对的?
