亲自用英语可以怎么说

"Personally" in English can be used to describe an action that is done by the speaker or writer themselves, rather than by someone else or by a machine. For example:
I personally prefer coffee to tea.
I'm going to personally deliver this package to the post office.
She personally cooked dinner for everyone.
Another way to say this in English is "by myself" or "on my own." For example:
I'm going to do this project by myself.
She cooked dinner for everyone on her own.
