PRESENT PERFECT

THE PRESENT PERFECT SIMPLE.

Presente Perfecto

El presente perfecto es en realidad una mezcla entre el presente y el pasado. Es  usado para hablar de acciones en el pasado que tienen importancia en el presente.

Para formar el presente perfecto, se usa el verbo auxiliar "to have" en el presente y el participio pasado del verbo. Para verbos regulares, el participio pasado es la forma simple del pasado.

Usos del presente perfecto

El present perfect es usado para:

• Acciones que comenzaron en el pasado y que no han terminado aún en el presente.

I have not eat in the past two days
No he comido en los últimos 2 días

• Acciones que comenzaron y acabaron en el pasado pero que su efecto continua en el presente.

I am not hungry because I have eaten a hamburguer
No tengo hambre porque he comido una hamburguesa
I have bought a house
(Yo) he comprado una casa

• Acciones que comenzaron y acabaron en el pasado pero que el interlocutor ha situado la acción en un intervalo de tiempo no acabado.

Intervalo temporal no finalizado:

I have been in Canada this year
He estado este año en Canada
