Explicación:
La estructura del 'present perfect' en forma afirmativa es:
Sujeto + have/has + past participle del verbo + (el resto de la oración)
Ejemplo:
I + have + answered + the question.
El past participle de los verbos regulares tiene la siguiente estructura: Infinitivo sin "to" + terminación -ed.
El presente perfecto en negativa se forma añadiendo not a have (o a has si se trata de la tercera persona del singular).
Sujeto + haven't/hasn't + past participle del verbo + (el resto de la oración)
Ejemplo:
I haven't answered the question.
Para la forma interrogativa usamos el auxiliar have (o has para la tercera persona del singular) seguido de la persona y del verbo principal en participio.
Have/has + sujeto + past participle del verbo + (el resto de la oración)
Ejemplo:
Have I answered the question?
