He turned the table.

他扭转了局面。

　　要理解这个句子，关键是理解固定短语turn the tables on somebody的意思。对此，英文的解释是，to suddenly take a position of strength or advantage that was formerly held by someone else，即，对……人反败为胜，转弱为强。在某些场景中，还有“与……互换座次”的意思。

例句：She played badly in the first set, but then she turned the tables on her opponent and won the match
在第一局她打得很糟，但她后来反败为胜并最终赢得了比赛。
