曼哈顿英文原版第237页中间部分,“Repeated pronouns are presumed to have the same antecedent. That is, every it and its in the sentence must refer to the same singular noun; every they, them, and their must refer to the same plural noun.”
亲,你怎么看?
they actually must refer to different antecedents; if they referred to the same antecedent, the latter would have to be "themselves" instead of "them".
analogy:
... she looked at her ... --> one woman is looking at another woman. (this sentence is not ok unless it's a component of some larger parallel structure that elucidates the pronouns, but you get the point)
... she looked at herself... --> a woman is looking at herself.
