recommit the same error 重蹈覆辙

“重蹈覆辙”，字面意思是“重新走上翻过车的老路（ follow the tracks of an  overturned cart）”，“辙”表示“车轮辗过的痕迹（ the track of a wheel）”。比喻不吸取教训，再走失败的老路，可以翻译为“recommit the same error”，“follow the same old disastrous road”。常用于劝说、希望和警告的场合。

例句：

要从过去的错误中吸取教训，以免重蹈覆辙。

One should learn from past mistakes so as to avoid falling into the same old trap again.
