标题: prep-2-177

177.
(31589-!-item-!-188;#058&006483)
(T-4-Q12)

For the farmer who takes care to keep them cool, providing them with high-energy feed, and milking them regularly, Holstein cows are producing an average of 2,275 gallons of milk each per year.

A. providing them with high-energy feed, and milking them regularly, Holstein cows are producing

B. providing them with high-energy feed, and milked regularly, the Holstein cow 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 答案：E

E. provided with high-energy feed, and milked regularly, Holstein cows will produce

这个题的主要考点都了解了，只是对正确选项还有一点不明：为什么and milked regularly前面还要加一个逗号呢？显然provided with high-energy feed和milked regularly所作的成分是一样的，直接用and连接不是很平行吗？

请NN指教！！！

provided和milked是分词的并列是表示被动意义（-ed），至于逗号的问题，我觉得没有什么大的影响，不知道有没有其他的说法。逗号显然不是这道题的考点，主要还是平行并列，时态。
