我还是自己写吧 贴别人的没有意思 就当回顾复习了
首先 看到题目的第一眼 就感觉应该是考察主谓一致 看下除A外的四个选项 果然如此
A项 向来是把原文抄下来 each of which =each of the spare teeth 因而应用is ;
B项 第一次看感觉Whenever 挺别扭 挺多余的 先放这里 看看下面的 ;
C项 主谓一致 each one of which is;
D项 The many 语感告诉我不对 应该是Many of the ；
E项 In后面是状语 each one ready to slide into the appropriate position后接whenever从句 但是each one ready to slide into the appropriate position没谓语 应该改为 each one is ready;
ALL IN ALL,选B.
如果没记错的话 我在GWD（管卫东）JJ上见过这道题……
愿高人指教!
P.S.我承认 我眼瘸了 E没错 each one ready 的确是独立主格结构 many后是个完整的句子
B项的确是语义错误,但C和D就不是语义错误了,有明显的语法错误,正如我上面分析的.
@ 4楼：语意是一方面,但我建议多从语法来考虑,毕竟这是GMAT语法上的题.也可能是我最近看语法上得看……谢谢4楼
In sum,E is the best choise.

一、词语注释：
an active tooth 一颗活动的牙齿
in the shark's jaws 鲨鱼的咽喉里
be lost or worn down 掉了或磨损
spare teeth 备用的牙齿
lie in reserve 留在那里准备更换
slide into the position 自动滑出补入到缺位
二、正误分析
A. When an active tooth in the shark's jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve, each of which are ready to slide into the appropriate position.
A 句中 an active tooth in the shark's jaws 应该是错误的，因为活动的牙齿是在嘴巴里，而不是咽喉里。在咽喉里的只是那些留着备用的牙齿（鲨鱼的特点就是咽喉里预备着备用的牙齿）
B. Whenever an active tooth is lost or worn down, many spare teeth lie in seemingly limitless reserve in the shark's jaws, which are each ready to slide into the appropriate position.
B 句语法和意思都没有错误。
C. Many spare teeth lie in seemingly limitless reserve in the shark’s jaws, each one of which are ready to slide into the appropriate position when an active tooth is lost or worn down.
C 句中的 each one of which（即 each one of the teeth）指的是“每一颗牙齿”，应该是单数，所以后面不能用 are，应该改为 is。

D. The many spare teeth lying in seemingly limitless reserve in the shark's jaws, each one of which is ready to slide into the appropriate position whenever an active tooth is lost or worn down.
D 句中 The many spare teeth 的定冠词 the（表示特指）与不定代词（表示泛指）many 在语法上用法冲突，应该改为 many spare teeth 或者 many of the spare teeth.
E. In the shark's jaws, many spare teeth lie in seemingly limitless reserve, each one ready to slide into the appropriate position whenever an active tooth is lost or worn down.

E 句中 each one ready to slide into the appropriate position whenever ...是带有逻辑主语的形容词 ready 的复合结构作陪衬性状语，也可以改为并列句 and each one is ready to slide into the appropriate position whenever ...

这个题我选e。
考得是非限定性定语从句。
首先，句子的意思就是说，鲨鱼的旧牙脱落时，它的备用牙好像是无限的，随时准备嵌入相应的空缺。
a的语义不对，因为它前面半句用的when，而后半句居然说lie in seemingly...，翻译过来是“当旧牙脱落，它的备用牙是无限的，这些备用牙随时准备填补空缺”肯定不如“当脱落时，备用牙随时填补空缺，这些牙似乎是无限的。”在脱落这个动...

b，c，d都存在的问题是，which只能指代逗号前紧跟的词，都指代了jaw，语义错误。
只有e是对的，用in the ...,表示一种长期存在的状态。
each one ready....是一个独立主格结构，没有错,如果是each one is ready反而错了，成了独立的句子，而独立的句子句首必须用连词链接。
