“飲水思源”，字面意思是“喝水的時(shí)候，要想到水是從哪里來(lái)的（When drinking water, one should not forget its source）”。

出自南北朝時(shí)期詩(shī)人庾信的《徵調(diào)曲》，“落其實(shí)者思其樹，飲其流者懷其源（When eating fruits, one should think of the fruit trees; when drinking water, one should think of the source of the river.）”。

庾信被迫在北朝客居二十多年，他常常思念故土，寫文章說(shuō)自己喝到河里的水就想到水的源頭，以此抒發(fā)對(duì)于南朝的情懷。后世將原文寫為“飲流懷源”或“飲水思源”，比喻不忘本、知感恩（one should never forget his origin and always be grateful）。可以翻譯為“gratitude for the source of benefit；never forget where one's happiness comes from”。

例句：

他是一個(gè)懂得飲水思源的人。
He never forgets his origin and always remembers the past kindness that he received.
