In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should acquire certain characteristics and partly because crossbreeding is said to provide hybrid vigor.
(A) in part that their steers should acquire certain characteristics
(B) in part for the acquisition of certain characteristics in their steers
(C) partly because of their steers acquiring certain characteristics
(D) partly because certain characteristics should be acquired by their steers
(E) partly to acquire certain characteristics in their steers
做题的时候我毫不犹豫的选了D,但是OG的解释是被动语态awkward
D awkwardly and illogically shifts to the passive voice: certain characteristics should be acquired by their steers;)
这题D确实很像正确答案，特别是一个should让人看了BY之后认为不应该轻易改变。
再分析分析句子的逻辑意思：D说certain characteristics应该由their steers来获取，E用to acquire表示cattle breeders have increasingly used crossbreeding的目的。
非划线部分partly because crossbreeding is said to provide hybrid vigor又阐述了一个原因。
一方面用来获取。。。一方面因为据说可以提供。。。一个目的，一个原因，使整个句子很有逻辑，优于D的“应该获取”意思。作者: haileywang 时间: 2011-4-27 21:52
E其实才是平行的
partly to acquire 和 partly to provide 平行~~ 表达了 increasingly
used crossbreeding的两个目的
D选项两个错误，一个是被动语态is awkward；一个是steer 不能 acquire

谢谢解答 多读几遍好像就觉得D越来越不对了 只是做题的时候一眼看上去
它真的很像答案！作者: bettyofariN 时间: 2011-5-4 06:42
是不是可以把“because crossbreeding is said”理解为 类似插入语的修饰成分，这样 to acquire 和 to provide的平行就看的更加清楚了。作者: 静若水 时间: 2011-5-5 06:33
