“反败为胜”，汉语成语，意思是扭转败局，变为胜利（snatch a victory out of defeat；turn defeat into victory）。与英文俗语“turn the table”意思相同，表示“to change from being in a weaker position in relation to someone else to being in a stronger position”。

例句：

客队最终反败为胜。

The guest team turned the table (on the home team) and won the game finally.

去年他们以3:0击败了我们，但是这次我们以5:0反败为胜。

They beat us 3-0 last year, but we turned the tables on them this time — we won 5-0.
