[讨论]关于并列结构

oddyuibe

一道语法题：
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.

D) partly because certain characteristics should be acquired by their steers
E) partly to acquire certain characteristics in their steers

从并列结构的角度出发，我选了D,但是，答案给的是E,觉得E读起来也不错，到底为什么E比D好呢？难道并列结构不是做题时首先用来的作判断的原则嘛？


谢谢指点

certain characteristics should be acquired by their steers  太罗嗦

partly to....partly because...构成的平行是逻辑上的平行
平行结构有时不是要形式完全一致。

哦，原来如此，谢谢
