In 1922, when Truman was almost forty years old, he was living in his mother-in-law’s house, watching the haberdashery store he opened three years earlier go bankrupt, and he faced a future with no visible prospects.

(A) opened three years earlier go bankrupt, and he faced

(B) opened three years earlier go bankrupt and faced

(C) had opened three years earlier go bankrupt, and he was facing

(D) had opened three years earlier go bankrupt, and facing

(E) was opening three years earlier going bankrupt, and facing

答案是D。我明白。

我想问的是，句中是不是three years earlier go bankrupt做时间状语修饰open? go bankrupt为什么go动词原形？这个结构我不太明白。有朋友能帮忙分析吗？

谢谢。
