THEY的指代问题？已解决

暗绯莎

如果是 复数and单数 的话，后面代词是用THEY吧
那PREP2-20:
[划线]The human nervous system and a telephone system bear a superficial resemblance because they both carry[划线] 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.

划线部分的THEY为什么没有指代对象啊？？~

they 不是已经指代The human nervous system and a telephone system了吗？

暗绯莎

我也是这么觉得的啊，但是答案解释这么说的啊

楼主！明明是两个单数名次啊，they 无法指代

暗绯莎

那两个单数名词中间用AND连接，后面的代词和谓语应该怎么用呢？

哎呀，我刚刚查了原题，我发现你搞错啦。
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.

(A) The human nervous system and a telephone system superficially resemble each other, not only because the former carries
(B) The human nervous system and a telephone system bear a superficial resemblance because they both carry
(C) The human nervous system bears a superficial resemblance to a telephone system both because the former carries
(D) Superficially, a telephone system resembles the human nervous system both because they carry
(E) There is a superficial resemblance between a telephone system and the human nervous system, not only because they both carry

GMAT Prep question
OA C

这里选C是没有疑问的，显然，只有 human nervous system 才能做主语，你哪里见过有神经突触和大脑的电话系统呢？B选项是一起做主语，天呐在我们有生之年此类发明这是不可能di ，童鞋。。。。
退一步来说，下文有一个its，就只能指代前文的一个单数名词。

还有，如果你非要纠结于这个A+B,代词用单复数的问题，我前天看过一位童鞋的总结挺有道理的，
拿which为例，
A+B，which   V.这种pattern，
如果A和B都是单数，which后面动词复数，没有歧义，which修饰A and B。
如果B是单数（不管A是单数还是复数），which后面动词也是单数，没有歧义，which修饰B。
如果B是复数（不管A是单数还是复数）则必须要用which together，没有歧义，这时which修饰A and Bs。

记得哦。。。要加together，不过我觉得加both也是同样的道理吧，

如果有误的话请牛牛指出来。！
