La forme interrogative du présent perfect est simple >>
Have/has + sujet + participe passé
S'il y a ever, never ... Il faudra le placé entre le sujet et le participe passé
Si tu dois mettre à la forme négative, tu rajoutes "not" après have/ has... > haven't / hasn't en forme contractée. C'est aussi simple que ça..
Sujet+ have not / has not / participe passé
S'il y a never... > entre have/has et participe passé

Bonne journée
