认识到自己的错误用英语怎么说

"Recognize one's own mistakes" 用英语可以说成 "acknowledge one's own mistakes" 或 "admit one's own mistakes".

这个说法来源于英语中动词 "acknowledge" 和 "admit" 的含义，"acknowledge" 意为 "承认，认可"，"admit" 意为 "承认，供认"。

例句：

I acknowledged my mistake and apologized for it. (我承认了我的错误并为此道歉)
He admitted to making a mistake and promised to do better in the future. (他承认犯了错误并承诺将来会做得更好)
