exhibits a preference of either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include
exhibits the preference to use either the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes
exhibit a preference in either using the right or the left hand (i.e., claw, paw, or foot) has been expanded to include
exhibit a preference for using either the right or the left hand (i.e., claw, paw, or foot) has been expanded to include
exhibit the preference as to either using the right or the left hand (i.e., claw, paw, or foot) has been expanded and includes
exhibit的主语不可能是the list, 逻辑不通，list不可能exhibits a preference of either using the right or the left hand，所以exhibit的主语必须是animals, AB去掉。剩下的不要看preference前后的小词，看either.....or.....只有D是对的，这样就出来了。先理解句子意思，再判断主干，抓大放小。
exhibit的逻辑主语是谁，不可能是list的，所以不可能用单数，AB错。
用语义比用语法可以更快排除AB，而且更准确
exhibit的主语不可能是the list, 逻辑不通，list不可能exhibits a preference of either using the right or the left hand，所以exhibit的主语必须是animals
either or平行
E 在and的平行结构下时态不对，一个是 has been, 一个present，但从句意上理解两者并没有实际的时间先后顺序差别。
这道题有点阴险。。。
preference for something
that 先行词 animals 后面不接s，排除 AB；
either or 平行结构，只剩下D了；
either or 平行结构，杀ACE
根据句意、临近原则，exhibit修饰animals，主谓一致杀AB
expend和include不平行，杀BE
错选B ，错误认为exhibits和has保持一致。"...list of animals that exhibits": the animals exhibit, not exhibits.
"错选B
either or 平行排除ACE
that代指是animals，只有animals才能exhibit preference，而不是list，排除B"
that 指代 animals, plural --> exhibit (a)(b) eliminated
exhibit 的主语是animals
preference for, either... or... 需要有相同成分
(D) 正确, 注意到了两个地方的主谓一致;the right和the left平行且使用to include避免了B选项的
错误----- and includes和has been平行,共同作为The list的谓语.则该
句子可化为The list… has been expanded the lower vertebrates和The list… includes the lower
vertebrates两个句子,前者明显不通.
1.either or
2.主谓一致 修饰的是animal
that 指代 animals, plural --> exhibit (a)(b) eliminated
(e) expand & include 是因果關係，不是並列關係。(e) eliminated
either...or 位置 (c) eliminated
主语是animals是复数所以谓语动词用单数，排除AB；either...or...前后一致排除CE，选D。
错误原因：词组搭配不过关 preference for 偏好
还是相信直觉吧
either 跟紧两个状态 而不是接动词
preference for偏爱; in preference to 优先于
