白勇语法上section 8第10题，请教NN

10.Unlike other arachnids, which have their nerve cells evenly distributed along their bodies, the scorpion nerve cells are clustered in its head, like a mammal's.

 (A) bodies, the scorpion nerve cells are clustered in its head, like a mammal's

 (B) bodies, the scorpion's head had a cluster of nerve cells, as a mammal does

(C) body, the scorpion has a cluster of nerve cells in its head, as a mammal does

(D) body, nerve cells are clustered in the scorpion's head, like a mammal's

(E) body, a cluster of nerve cells is in the scorpion's head, like a mammal's

答案选C  但不明白为什么用body,不是their bodies 呢？  请教牛牛

大全注解里的解释：

A) bodies错, 每个动物只有一个身体，如果是bodies说明它们每个有多个身体。other arachnids和the scorpion’s nerve cells比较不对等。
B) the scorpion’s head和other arachnids比较不对等。
C) best. 大全已把scorpions改成单数scorpion。
D) other arachnids和nerve cells比较不对等。
E)同理上

同样疑惑。

记得OG上面有过类似的单复数问题，好像当时OG就反驳了their X(单数）这种说法，说这样意味着多个#share一个X,这里不是可以同理推出用body意味着他们share 一个body呢？

大全注解哪里有啊  能发个给我吗  hedyqian(A) hotmail.com  先谢谢了

没有收到  555。。。 不知方不方便再发这个试试  太麻烦了 hedyqianer[在] yahoo.com.cn

把这句话接复数形式和单数形式表达的意思分别理解一下,记住这两者表达出的含义的是不同的,下次再遇到就不会再困惑了.
