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 E. provided with high-energy feed, and milked regularly, Holstein cows will produce
这题选E,看过以前的讨论都是关于provided milked的,这个我明白,选的时候我选的是D 因为看到了最后的each per year 所以认为是单数..... 求解为什么要用复数 THX作者: Jennifer789 时间: 2010-2-17 14:21
For the farmer who takes care to keep them cool, 因为这里出现了them啊 所以是复数呀作者: duolaime 时间: 2010-2-17 21:52
但是那个each的问题.... 如果没有for那句的them作为线索的话~~~~作者: cx_ding 时间: 2010-2-18 05:53
them指代牛们。 另外,请楼主告知一下讨论结果,为什么用过去时?作者: duolaime 时间: 2010-2-18 16:16
理解是For the farmer who takes care to keep them cool 只是状语,可以把它放最后。 这样这个句子就成为了 provided them with high-energy feed, and milked them regularly, Holstein cows............ for the farmer......这样就可以理解了把~ 看成倒装~作者: 张大猴 时间: 2010-2-18 17:54
For the farmer who takes care to keep them cool, provided with high-energy feed, and milked regularly, Holstein cows will produce an average of 2,275 gallons of milk each per year. each per year是状语 对句子的单复数没有影响 provided是表示被动不是过去式 逻辑主语是holstein cows这些牛
