请教一道OG上面的语法题

tateUID: 2554796

SAT OG第661页 20题：In 1850Jim Beckwourth, a Black American explorer, discovered in the mountains of the Sierra Nevada a pass soon becoming an important gateway to California gold-rush country.
1 Q8 A; B$ _7 z  _本人认为这道题没错，becoming现在分词作后置定语修饰a pass, 而有答案解释说应把becoming改为that would soon become,我认为没有必要，请高手赐教，谢谢！

"Soon becoming" should be perfect tense, which does not really fit into the sentence. "In 1850" and "discovered in the mountains" tell us that this sentence is in past tense, so using "that would soon become" fits into the tense of the sentence well. Saying "a pass that would soon become" make the sentence more fluent, so it should be right.

首先，谢谢你的回复，但是我认为soon becoming是非谓语动词，和你所说的时态没有关系（tense),这个句子整体是过去时，这一点没有问题，但这里becoming是现在分词作定语修饰pass,他们有逻辑上的主谓关系。所以我认为从时态的角度解决这道问题是站不住脚的。谢谢！

"现在分词作定语时表示动作正在进行或与谓语动词所表示的动作几乎同时发生。如果两个动作有先有后，一般不能用现在分词作定语，而要用定语从句"
