以下是引用remeo在2003-10-25 8:45:00的发言: 91. The distribution of mass within the core of the Earth, like the mantle that surrounds the core, has been deduced from the orbital behavior of the Earth and the motions of satellites controlled by the gravity of the Earth. (A) the mantle that surrounds the core (B) that within the mantle surrounding the core (C) that of the mantle surrounding the core (D) the mantle the core surrounds (E) the distribution of mass within the mantle that surrounds the core 答案是B,这里的that显然代替了distribution of mass.可是根据我的理解that只能代替核心词distribution,应该只有it才能代替整个词组distribution of mass?
