The human nervous system and a telephone system superficially resemble each other, not only because the former carries information in the form of electrical impulses and because all of its neural pathways converge in the brain and spinal cord, which together form a kind of central exchange.

B的both and没有平行作者: yunshishow 时间: 2011-8-30 09:10
B答案，如果they可以指代The human nervous system and a telephone system 的话，both就是修饰The human nervous system and a telephone system的 。后面的and because和前面的because平行，这样理解的话并不是both...and...句型。作者: bitieming 时间: 2011-8-30 16:26
如果选B的话，后面的its没有指代对象。 要从逻辑含义理解句子，第二个because后面明显描述的是神经系统可以resemble电话的一些特征，则第一个because也应该是在描述神经系统的特征，而不是两者的共同点。作者: yunshishow 时间: 2011-8-30 18:25
