1. For the farmer who takes care to keep them cool, providing them with high-energy feed, and miking them regularly, Holstein cows are producing ana average of 2,275 gallons of milk each per year.
A. providing them with high-energy feed, and miking them regularly, Holstein cows are producing
B. providing them with high-energy feed, and miked regularly, the Holstein cows produces
C. providing with high-energy feed, and miking them regularly, Holstein cows are producing
D. provided with high-energy feed, and miked regularly, the Holstein cows produces
E. provided with high-energy feed, and miked regularly, Holstein cows will produce
这题选E, 我选错了。。。 想问两个问题： 1. the holstein cows为啥不行， 为什么前面不加the？
2. 因为句尾each per year,所以我以为用一般现在时“ are producing”会比较好？ 一般有each per year这类词的用什么语法时态比较好？
2. Only seven people this century have been killed by the great white shark, the man-eater of the movies---less than those killed by bee stings.
A. movies---less than those
B. movies---fewer than have been
C. movies, which is less than those
D. movies, a numbber lower than the people
E. movies, fewer than the ones
这题选b， 我选的d。。想问： 1. 为什么d 不行？
2. b中movies 后的破折号不会有歧义吗？让人误以为"fewer than .." 是修饰“the man-eater of the movies”的？
3. In the mid-1920s the Hawthorne Works of the Western Electric Company was the scene of an intensive series of experiments that would investigate changes in working conditions as to their effects on workers' performance.
A. that would investigate changes in working conditions as to their effects on workers' performance

C. for investigating what the effects on workers' performance are that changes in working conditions would cause
D that investigate changes in working conditions' effects on workers' performance
E. to investigate what the effects changes in working conditions would have on workers' performance
这题选b，我选的a。。我不懂的是：1. a中的as to 是用错了吗？ as to 一般用在什么地方呢？
2. b中的句子结构是怎样的？ 是 effects［ that changes in working conditions（修饰effects）］ would have on workers' performance？ 还是 effects ［that changes in working conditions would have on workers' performance］？没搞清。。。

这题选C, 我想问一下： c中的"coming from sales...." 是做动词还是做修饰词修饰increase？ 如果是做动词的话单coming一个词的话是个incomplete verb吧？那么这个句子就是个fragment啊，如果是做修饰词的话那也是个fragment啊这句子。。不知道怎么理解了。。。
