还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
acquire . . . is ungrammatical.
B In part should be partly. Use of prepositional phrases is wordy and
awkward.
C Because of suggests that crossbreeding has occurred because the steers
have already acquired certain characteristics.
E Correct. In this sentence, the word partly is used to introduce both
reasons; the phrase to acquire certain characteristics is clear and concise.
你可以观察一下选项DE，真正的差距是，选项E是一个目的状语，acquire的逻辑主语是cattle breeders。如果补全就是：cattle breeders acquire certain characteristics in their steers.
再观察D选项：
certain characteristics should be acquired by their steers.
两个选项真正的差距在于，D中没有说明是谁想让小牛们获得这些新特征，而选项E指明是cattle breeders想让小牛获得特征的。你想，划线部分必须要求和In recent years cattle breeders have increasingly used crossbreeding形成因果或目的关系，如果不指明是cattle breeders想让小牛获得特征，则划线部分和主句之间无法具备因果关系~
只能说“因为养牛者想让小牛获得新特征，所以他们会用杂交这个技术”。不能说“因为小牛可以获得新特征，所以养牛者用杂交这个技术”。
