"多年以后" 的英文翻译是 "after many years". 这个短语来源于拉丁语， "post" 意为 "after"，"annum" 意为 "year"。

例句：

After many years, I finally got the job of my dreams. (多年以后，我终于得到了我梦寐以求的工作。)

I can't wait to see what the world will be like after many years. (我迫不及待想知道多年以后的世界会是什么样子。)

After many years of hard work, he finally retired comfortably. (多年的努力工作之后，他终于安享晚年。)
