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
