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

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

这题本身没什么问题，但是为啥笔记解释说(D) it表语从句用法错误，第二个is多余
这个怎么判断，为什么多余？

be sb'doing 结构不对吧

作者: alicejingli 时间: 2011-3-27 18:33
没明白楼上的，be sb's doing?不是吧，their being done不对，但是笔记说是表语从句，不明白，等斑竹/NN解答

建议能把标题改一改，标题写错了，另外这题我也是不懂，我还以为DE是形式主语。。
