Sujeto + Have / Has + Pasado Participio del verbo + el resto de la oración.
En este Tiempo Verbal, el uso del auxiliar "Have - Has" depende del Sujeto de la oración.
Si el Sujeto es o equivale a "He – She – It", se escribe el auxiliar "Has" + Pasado Participio del Verbo.
Si el Sujeto es o equivale a "I – You – We – They", se escribe el auxiliar "Have" + Pasado Participio del Verbo.
Si el Verbo de la oración es Regular, el Pasado Participio es igual al Pasado Simple, se agrega "–ed" al final del verbo.
Si el Verbo de la oración es Irregular, se escribe como figura en la 3° columna de los Verbos Irregulares (Pasado Participio).
