Sam‘s been working in the garden since 8 o’clock this morning. - Continuous activities which started in the past and continue into the present with focus on the length of the activity (often longer than expected), I’ve been trying to call Dr. Tate’s practice all day, but I just can’t get through. - repeated actions up to the present, Ella has been writing songs for more than 10 years - to add emphasis to an activity rather than a quantity/result, Freddie: Why are you all red? David: I’ve been sunbathing. - a recent activity where a result is still visible.,
