・one instance shows all
・one instance could be applicable to anything

「以一知萬」的英語可以說 one instance shows all 或 one instance could be applicable to anything 兩種表達方式。

One instance shows all. Please adhere to deadlines and times.
（以一知萬。請遵守截止日期和時間。）
※ adhere（遵守，堅持，執著，等等）
※ deadline（最後期限，截止日期）

Why don't you always report properly? One instance could be applicable to anything.
（為什麼你總是不好好報告？這可是以一知萬的道理。）
