Ответ:
Present perfect - have/has+V³(e.g. done)
Present perfect continuous - have/has+been+V+ing(e.g. doing)
Объяснение:
Например:
Present perfect:
I have done it since 3 o'clock
Present continuous:
I have been doing it for 3 hours.
Разница в том, что Present perfect continuous указывает на длительное действие.
