According to one expert, the cause of genetic irregularities in many breeds of dog is not so much
that dogs are being bred for looks or to meet other narrow criteria as that the breeds have relatively
few founding members.

(A) the cause of genetic irregularities in many breeds of dog is not so much that dogs are being
bred for looks or to meet other narrow criteria
(B) the cause of genetic irregularities in many breeds of dog is not as much their being bred for
looks or meeting other narrow criteria as much
(C) it is not so much the cause of genetic irregularities in many breeds of dog that they are being
bred for looks or meeting other narrow criteria as much
(D) it is not so much that the cause of genetic irregularities in many breeds of dog is their being bred
for looks or meeting other narrow criteria so much
(E) it is not so much the cause of genetic irregularities in many breeds of dog to be bred for looks or
to meet other narrow criteria


答案是A
老语法笔记上的解释不太明白
说CDE it表语从句用法错 能具体点是哪里错吗
还有可以具体解释一下

(A)正确，for looks or to meet平行修饰谓语bred，是功能平行而不是形式平行，表示be bred的目的。 还有就是这里for looks or to meet平行修饰谓语是什么意思 跟谁平行
