if…then…结构要同主同被,if they lose one arm(主动)it is quickly replaced(被动);commaV-ing用法错,要体现前后次序。
if A(then) B 结构要求平行。A是主动态,B也要是主动态。If they lose one arm they replace a new arm
条件从句主动,结果从句被动。 overcompensating,和growing 逻辑关系不清楚。(有多重理解)
overcompensating and growing 是两个应该平行的部分
overcompensating 与 growing 应该并列 中间差and
if A(then) B 结构要求平行
(1) In addition, unlike A and B, which tell us "with/by the animal overcompensating and growing extra arms", C through E tell us "with/by the animal overcompensating, growing extra arms". The linkage in A and B is more appropriate since these actions occur in sequence. The animal indeed overcompensates and grows extra arms. This can be used to eliminate C, D and E (2) A, D and E break the flow of the sentence by having a mismatch of active and passive voice in the condition and consequence. A is passive->active (if one arm is lost it replaces it) while D and E are active->passive (if they lose one arm it is quickly replaced). Ideally, both clauses would be active ("if they lose one arm they quickly replace it" as in C). The next best option is to have two passive options ("if one arm is lost it is quickly replaced"). This can be used to eliminate A, D, and E

if A(then) B 结构要求平行。A是主动态,B也要是主动态。If they lose one arm they replace a new arm
if A(then) B 结构要求平行。A是主动态,B也要是主动态。If they lose one arm they replace a new arm
1,sometimes 2,it is replaced with arm(should be arm)
