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.
providing them with high-energy feed, and milking them regularly, Holstein cows are producing
providing them with high-energy feed, and milked regularly, the Holstein cow produces
provided with high-energy feed, and milking them regularly, Holstein cows are producing
provided with high-energy feed, and milked regularly, the Holstein cow produces
provided with high-energy feed, and milked regularly, Holstein cows will produce
题目分析：
本题主要的难度在于看懂题意，把倒装句看清楚。要注意，平行的对象并不是take care，provide，和milk。正常的语序为：
Provided with high-energy feed, and miked regularly, Holstein cows will produce an average of 2,275 gallons of mild each per year for the farmer who takes care to keep them cool。
选项分析：
A选项：providing them with high-energy feed和milking them regularly是现在分词短语，在字面上做keep them cool的伴随状语。这在逻辑上是不对的。因为伴随状语的本质是普通的状语从句，但是“提供高能量食物”、“规律性的喂奶”、“保证奶牛们凉爽”是三个不同层面的事情，应该是并列关系，不能是互相修饰的关系。
B选项：providing them with high-energy feed是主动语态，主语必须是the farmer，但milked regularly是被动语态，主语必须是the Holstein cow，因此两者无法平行。
C选项：本选项错误在原理上和选项(B)相同，只不过是将provide部分和milk部分交换了一下。
D选项：代词them的必须指代复数名词，但本选项中的the holstein cow是单数名词，所以本选项是不正确的。。
E选项：Correct. 本选项在语法和逻辑上均是正确的。调整句子语序则有：Provided with high-energy feed, and miked regularly, Holstein cows will produce an average of 2,275 gallons of mild each per year for the farmer who takes care to keep them cool。
错选D，D：题目中未划线部分的them已经规定了要用cows，不能cow
这题是一个倒装句，不是考平行，所以要读懂语义，找到provided和milked的承受者是cows
补充，感觉这题时态用will或者一般现在时都可以

读题下来发现A没有硬伤，留着；BC都存在通过一个问题， and前后的成分不平行，排除BC；句子前面没有划线部分已经说了 them，那就不可能用单数，排除D；读E发现E也没有硬伤，最后在A和E中间纠结：
Ron关于A为什么错的解释有二：
第一，中间的providing...and milking...从语法上可以对，但是意义上不对，因为用Verb-ing的情况必须【同时】满足两个条件：第一 Verb-ing的主语是指前面句子的主语；第二Verb-ing是表达的要么是前面句子的结果，要么是同步发生的事件。Ron认为第一个条件满足，第二个条件不满足。我觉得解释为“同步发生的事件”是可行的，没毛病（Farmers takes care to keep..., providing...and milking...），可能是因为我理解的这个“同步发生”跟Ron说的不太一样，他说的同步，必须是极其明显的同步，比如说Tom talked to his mother on the way to school, eating the bread meanwhile.
第二，他认为从native speaker的角度来看，这个are producing的用法非常akward，原因是正在进行时的时态emphasizes the ongoing nature of an action; it specifically emphasizes that an action is taking place, right now, as we speak.。而这个句子是在表述某种状态，"to state an eternal truth. for that, the present tense is used".，用正在进行时不合适。
*Ron说还有一个小错误：note that you also can't say "THE holstein cows", unless you're referencing a particular, specific, known group of holstein cows (something that you clearly aren't doing). since you're talking about holstein cows in general, you don't use the article "the".
Holstein cows是个普通概念，泛指；the Holstein cow则指的是特定的一群/一类Holstein cow
1.代词，前面有them后面必须是复数，BD错
2.平行，BC不平行
3.句意推理，是牛milk，产奶，所以不能用milk them，AC错
4.句子结构，这里是倒装，provide这一部分都是修饰牛的，不能用provide them,AB错
D选项：代词them的必须指代复数名词，但本选项中的the holstein cow是单数名词，所以本选项是不正确的。。
有casual relationship就可以用will
题主要的难度在于看懂题意，把倒装句看清楚
"For the farmer who takes care to keep them cool" could be removed to the end of the sentence.
always remember that the cows are the subject.
考察：
单复数主谓一致；语意；
错选d
前：倒装for； provided and milked应该是修饰cow的伴随状语，因为这种伴随状语总是主语前。所以是被提供；
后：produce还是produces/are producing；注意“keep them cool”从未画线部分看出主语应该是cow还是cows，选项中明显的区别这次忽略了，一般距离较远的未画线部分代词等会去提示单复数
D选项：代词them必须指代复数名词。
the Holstein cow
Holstein cows
keep them cool
注意单复数考点
把倒装句看清楚。要注意，平行的对象并不是take care，provide，和milk。正常的语序为：
Provided with high-energy feed, and miked regularly, Holstein cows will produce an average of 2,275 gallons of mild each per year for the farmer who takes care to keep them cool。
倒装
这道题错的非常典型！！
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.
keep them cool // keep them provided with... // keep them milked regularly ...!!!keep+v-ed/adj.
（理不清题目结构的时候还固执地按照一个方式去理解 只有做错！没有读懂本身意思或者不能准确解释题目含义的最后都只有做错！）
知道逻辑主语应该是cows还会选错。。。
keep them cool...them.
如果非要纠结的话，prep08解释：泛指牛不加the；will除了表示将来时，还可以常常发生的事；
而且，prep08笔记把E理解为：cool，provided，milked三者并列做keep的宾补。感觉也说得通
the Holstein cow produces
Holstein cows will produce
加不加the 和 用不用will，都不重要
1.provide，milk两个动作：若主语是farmer，则应和前面的to keep并列，且provide后加them；
若主语是cows，则应用被动，且provide不加them，直接provided with
2.未划线部分的them，应指代cows，复数！！！
3.正确选项，用will将来时，可以接受，不算错误
them
