為什麼這個句子裡要用 "had earned" 這個過去分詞?

這是一個過去完成式的句子,這個動詞時態用於講述在過去某個時間點之前完成的動作。這種用法在重述過去發生的事情時特別有用,因為這樣一來可以更清楚地描述事情的先後順序、形成相比。 例句: If I had woken up earlier today, I would not have been late for school. (如果我今天早起,上學就不會遲到了。) 例句: The old hotel was abandoned now. It had once been famous for serving celebrities and politicians, but now only spiders and mice could be seen wandering across its halls. (老旅館現在已經廢棄。它曾經以服務明星與政治人物而聞名,但現在只能看到蜘蛛和老鼠在它的大廳裡徘徊。)
