1. 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, 我有点不明白为什么是A, 记得xdf老师讲"being" 90％ 都是错的，即使这道题正好是10％对的那个，我也想不明白为什么这里要用“being”？和后面的to meet也不对称啊。 而且E答案错在哪里？我觉得to be bred 和to meet蛮对称的

还是不是很明白，怎样分析这道题而得出正确答案呢？

"...so much that dogs are being bred for looks or to meet other narrow criteria as that..."
我理解完整形式是so much that dogs are being bred for looks or (dogs are being bred) to meet other narrow criteria as that，因而是对称的。

not so much that...as that....平行
按照你的说法，being 还是有10%的情况是对的，这里的是被动的进项时态
sth. be being done by sb.
