补充 97

97. Unlike that of human beings, who waste away when they go without food for long periods, hibernating bears exist for months on only their excess fat.

(A) Unlike that of human beings, who waste away when they go

(B) Unlike human beings, who waste away when they go

(C) Unlike human beings, wasting away when going

(D) Dissimilar to human beings, wasting away when（B）

(E) Lacking similarity to human beings, who waste away when

该题答案为B！

  但：

     该题B中they,应该不对，应指代human beings, 但原句后半部有个their ，已指代bears.

     因此，本题答案B应该有问题。有过路的给个解释啊！

   一个句子，这样的代词指代是否允许啊，请NN有没有别的例子可举啊？比较怀疑本题的代词指代一致问题啊！

   请NN明示！
