prep08 sc177 弱弱地问一个句子

891758149

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.

无理由使用are producing进行时态，
native speakers of english will recognize "are producing" at once as awkward。

cows 每年生产milk 用进行时很正常啊  为什么会累赘？

谢谢各位大侠~~

for.....,provided with high-energy feed, and miked regularly ,cows ...可以这样用吗 前面不是有for引导的从句,这是什么结构a?

我也对这道题很迷茫，感觉两个选项都没具体的语法错误，非要说，are doing确实没有一般现在时好，但keep sb provided一样很别扭呀。
