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．
我怎么觉得D更平行啊？两个partly because后面都是被动句？？ |
