114. Starfish, with anywhere from five to eight arms, have a strong regenerative ability, and if
one arm is lost it quickly replaces it, sometimes by the animal overcompensating and
growing an extra one or two.

(A) one arm is lost it quickly replaces it, sometimes by the animal overcompensating and

(B) one arm is lost it is quickly replaced, with the animal sometimes overcompensating and

(C) they lose one arm they quickly replace it, sometimes by the animal overcompensating,

(D) they lose one arm they are quickly replaced, with the animal sometimes overcompensating,

(E) they lose one arm it is quickly replaced, sometimes with the animal overcompensating,

这一题答案是B哦，但是不明白为什么，嘻嘻~

1) 如果一个 Starfish 断了一个 arm, 那么这个 Starfish 就会再生长替换掉这个断的 arm.
2) .......这些 Starfish ....................., .......这些 Starfish ................................................

比较以上两种说法，在语义上，第1种表达是准确的。所以 CDE 错误，因为都用了 they lose... they replace...

A选项，有两个it. 这两个it分别要代表 the animal 和 one arm. 容易混淆，表达错误。因此A也错。

答案是B。

其实我也不太明白啊,这里with起什么作用阿,我一看with就想到独立主格.
还有这个overcompensating and growing到底是对称还是怎么找，我怎么总觉得逻辑不通阿，
