● We can also use the Present Perfect Continuous to talk about an action or situation that began in the past and has just finished.
-What have you been doing for the past hour? I’ve been reading my book.
● The Present Perfect Continuous is often used with expressions of time, to focus on how long something has been happening.
-I have been waiting for you for half an hour. She has been working since 8 am.
● The Present Perfect Continuous is formed with has/have + been + the present participle (-ing form).
