Explicație:
De obicei, folosim acelasi timp în aceeași propozitie. Nu zicem "Soarele apune si vântul batea" (The sun is setting and the wind was blowing) pt ca nu are sens.
Folosim "has" atunci cand vorbing despre o actiune din trecut care s-a desfasurat nu de asa mult timp
Folosim "has been" cand vorbim despre o actiune din trecut care inca nu era terminata la timpul actiunii.
