承认做某事怎么说英语

To admit to doing something in English, you can say "I admit to doing [something]" or "I confess to doing [something]." For example:
I admit to making a mistake.
I confess to lying about my age.
Alternatively, you can use the verb "acknowledge" to express that you accept or recognize something:
I acknowledge that I was wrong.
I acknowledge my responsibility for the situation.
Keep in mind that admitting or confessing to something often carries a sense of guilt or remorse, while acknowledging something may not necessarily imply those feelings.
