请教prep1中的第六题~~~

本来应该是道很简单的题哈~~但是我突然弄不明白一些问题~~请大家指点指点~~

The list of animals that exhibits a preference of either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include the lower vertebrates.

(A) exhibits a preference of either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include

(B) exhibits the preference to use either the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes

(C) exhibit a preference in either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include

(D) exhibit a preference for using either the right or the left hand (i.e., claw, paw, or foot) has been expanded to include

(E) exhibit the preference as to either using the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes

选项选的是D~~当然也只有D中的preference的搭配是对的~~~

但是我对于为什么用exhibit而不是用exhibits很困惑~~答案解释的是用复数是因为that 修饰的animals ~~~

但是不是说在类似于list of 这种情况下都应该随list用单数吗？？而且貌似有很多其他的题就是按list来用单数的~~~

是不是这道题有什么不同的地方或者到底在哪种情况下应该用看list,哪种情况下应该看of后面修饰的名词 ，希望大家指点下迷津~~

PS：是不是这种情况就是要看所谓的A OF B中的A，B谁才是中心词？但是我记得有次我这么做又错了~~我暂时又没有找到其他的例子~~~    

n1 of n2 that 谓语的单复数由that修饰的对象决定

题中that句子里说展现出用左手或右手的偏好,很显然是在说动物而不是list,而动物是复数,所以用exhibit

所以说这种类型的题要去看that到底修饰谁,而不要自己去判断n1,n2谁才是中心词

谢谢MM～～那这个和the only one of  ns   ...that +单数冲突不呢？

不冲突,分开记吧
