老师好，
描述故事梗概应用 一般现在时。为了进一步了解这一语法现象，我查阅了大不列颠百科的网页版后发现：只有在讲故事主线时这一规则才适用，如果在叙述主线的过程中，叙述主线的过去或将来的情况，该用什么时态就用什么时态。我大部分的情况都可以理解，只是确定不了 过去完成时：
https://www.britannica.com/topic/La-traviata
Gastone tells her that during her recent illness, Alfredo had inquired after her daily. Violetta, amused, cannot understand why and teases her lover, Baron Douphol, that he did not do the same.
也就是说Gastone现在病已经好了
https://www.britannica.com/topic/The-Red-and-the-Black
The book ends with Sorel’s execution for the attempted murder of Mme de Rênal after she had jeopardized his projected marriage to Mathilde.
这意味jeopardized发生在 蓄意谋杀之前
还有这句（这句不是大不列颠百科上的，来源不一定可靠）
One day, the “Schofield Kid” (Jaimz Woolvett) comes along with news of a $1,000 reward for killing two cowboys who had cut up a prostitute.
cut up发生在发布消息之前
这是 过去完成时的 什么用法？用句中的某个名词暗示过去的某个时间点？请教老师相关的用法。
