OG11紫皮22-奇怪的平行对称

OG11紫皮22

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

Parallelism + Rhetorical construction

The sentence gives two reasons that cattle breeders use crossbreeding；these reasons should be introduced in parallel ways with the word partly．The infinitive to acquire clearly and concisely conveys the purpose of the crossbreeding．

A  In part should be partly；use of relative clause is ungrammatical．

B  In part should be partly；wordy and awkward use of prepositional phrases．

C  Because of suggests that crossbreeding has occurred because the steers have already acquired certain characteristics．

D  Passive voice should be acquired by is awkward and illogical．

E  Correct．In this sentence，the word partly is used to introduce both reasons；the phrase to acquire certain characteristics is clear and concise．

The correct answer is E．

我选了D，因为partly because要对称，看了解释觉得E可能更好，但是这样就算平行了? 感觉怪怪的，向NNs请教, thx

lz应该把平行的范围想的开阔一些 平行并不是死死的要求表面形式上平行 有时候二者在句中的作用或表达的意思想对称也可以作为平行结构的表达 就如本题中 两个部分都是表达cattle breeders used crossbreeding的理由

如果是D  partly because 这么生硬地重复两遍实在累赘 应该去掉后面的那个 而且D中的被动也不如E中主动好

谢谢MM啦，恩，我已经想通了，看来做题不能太快...当时做的时候只看了2个单词...
