问题 In recent years cattle breeders have increasingly used crossbreeding, in part that their steers should acquire certain characteristic and partly because crossbreeding is said to provide hybrid vigor.
选项 A、in part that their steers should acquire certain characteristic
B、in part for the acquisition of certain characteristic in their steers
C、partly because of their steers acquiring certain characteristic
D、partly because certain characteristic should be acquired by their steers
E、partly to acquire certain characteristic in their steers
答案 E
解析 本题看似很简单，根据未划线后半部分中的partly because及之前的and，可以推断划线部分是与之结构相似的并列成分，立刻选出D。但答案不是D，而是E。该题同样要从题意上理解，假若D对：(1)它虽然遵守并列形式对称一致的原则，但却违背主动优先原则；(2)更重要的是，D选项与前半部分连接之后，即“因为被阉割的牛可以获得某些特性，所以养牛者在近年来扩大了对交叉饲养的使用”，与前半部分之间的因果逻辑关系并不明确；而再看与之并列的未划线的because从句，其与前半句因果关系却很明确。为什么?因为它在because从句提到了crossbreeding，这才是前后有因果关系的关键。由此，可以排除D，而选E。E中的动词不定式表目的，该选项结构、句意清晰；值得指出的是：该选项是一个表目的的动词不定式和表原因的从句相并列，形式上、功能上并不一致。之所以这样只是为了达到句意的准确和清楚。
