OG 204 ?

204. 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.fficeffice" />

(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

老姨说选e，　说省略部分东西了：

。.....    partly because crossbreeding is said to provide hybrid vigor.

         (E)         partly ( because crossbreeding is said ) to acquire certain characteristics in their steers    

有这样的省略形式么？　那个字典上有说阿，　请帮我解释一下　

不是吧？这里acquire的执行者到底是谁啊？是cattle breeders还是crossbreeding啊？

如果是前置省略的话，那acquire的主语就成了crossbreeding了。---可我觉得这逻辑上不通吧？

请NN帮忙啊......

In recent years cattle breeders have increasingly used crossbreeding,

partly to acquire certain characteristics in their steers

cattle breeders  use crossbredding to acquire certain...........

and partly because crossbreeding is said to provide hybrid vigor.

bebexu:我同意你的看法,所以说这里并不是什么前置省略吧?因为如果是前置省略,就成了partly because crossbreeding is said to acquire certain....了,就成了crossbreeding是acquire的逻辑主语了.这样是不对的吧?
