Che cos’è il Present Perfect?
Usiamo il tempo Present Perfect per parlare di:

2. Esperienze passate (senza dire quando sono avvenute)
-

3. Azioni appena avvenute (passato recente)
-

4. Azioni avvenute nel passato ma che hanno un effetto sul presente
-
He has lost his keys. (He still doesn’t have them.)
