B) providing them with high-energy feed, and milked regularly, the Holstein cow are produces

C) provided with high-energy feed, and milking them regularly, Holstein cows are producing

D) provided with high-energy feed, and milked regularly, the Holstein cow produces

E) provided with high-energy feed, and milked regularly, Holstein cows will produce
上看下看，左看右看，那个选项都别扭，只好本着矬子里边拔大个儿的原则，选D，各位有何高见。谢谢！

用一句俗话，I can't agree with you more. hehe.但是，从句子结构来讲，D也是很别扭的。

愚以为，如果作如下调整，有可能还能顺畅一些：

Provided with high-energy feed, and milked regularly, the LACE w:st="on">HolsteinLACE> cow produces an average of 2,275 gallons of milk each per year for the farmer who takes care to keep them cool.老兄以为哪？

同意！或者将for the farmer who takes care to keep them cool夹在中间，即" Provided with high-energy feed, and milked regularly, the Holstein cow, for the farmer who takes care to keep them cool, produces an average of 2,275 gallons of milk each year.　似乎更好些，老兄以为哪？

可参见如下：

谢谢jnlvo版主，这个帖子不大好搜。

有可能，考试时再注意下。如你所改应该是D。

我觉得天山4-12和本题都应该是选A. them很清晰的指代了cows.

E. 不用看后面的单复数, For the farmer, provided with high energy feed, .. Holstein cows will produce 就已经有修饰的歧义了.

从网上搜来的句子

For the farmer who takes care to keep them cool, sated with high-energy chow, and milked regularly—often under the management of a sophisticated computer—these familiar black-and-white cows produce an average of 2,275 gallons of milk each per year.

可以看出这里provided with high-energy feed, and milked regularly作形容词看待和cool平行。D如果是Holstein cows produce，则比E的will好。A可能会产生歧义 keep them providing them with high-energy feed，或者keep them cool，providing them with high-energy feed, 本来应该平行的结构，变成了伴随，意思表达感觉不好。还有一种可能的歧义providing them with high-energy feed，Holstein cows are produceing。
