1. 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.

3. 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.
4. 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.
5. 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.

答案是a

刚开始也是选的a,可是在看看觉得e更好一点吧~~

a中"...each of which are..."，are不对吧？

are肯定不对，而且each of which可能会有歧义修饰reserve,同意E,many..., each one...这种结构比较好

open to discuss

E不对，没有谓语

In the shark’s jaws, many spare teeth lie in seemingly limitless reserve, each one （IS）ready to slide into the appropriate position whenever an active tooth is lost or worn down.

我选的D

回楼上:is有了才是标准的run on sentence了,两个句子没有任何连词

觉得A的each of which are单复数的确有待商榷,但是这个are消除了which指代reserve的歧义,如果改成is,才会造成歧义

但是E也觉得不好,主要觉得,one的指代就没有问题么? whenever=when? In the shark’s jaws变成修饰整个句子了,难道没有distort the meaning?

D,前面就算是个独立主格,后面each one of which,用了which窃以为就算是定语从句了,那么就根本是fragment吧

请批评指正~

个人认为选E, each one 为tooth同位语.A中each of which 用is必错！欢迎各位讨论。

A的句子结构是有问题的。只在鲨鱼的牙掉了的时候，它才有很多其他的牙？这个When的从句修饰的是什么？意思上来看，牙掉了的时候，会有新牙补上才对吧？

E不用加is, 否则就是Run-on sentence了。这里ready 是独立的形容词结构，前面有自己独立的主语 each one, 没问题。更主要的是，这句解决了A中when从句修饰对象不正确的问题。

强烈支持E

我同意选E

A选项，each of which 应该是is，

E中的 each one ready to slide into the appropriate position whenever an active tooth is lost or worn down，是独立主格结构，加了is反而不对，因为两个句子中间没有任何连词。这种情况是必错的。

支持E
