Pretérito perfecto compuesto continuo


AFIRMATIVA:
Sujeto + have / has + been + forma ing del verbo principal

I have been eating
He has been eating


NEGATIVA:
Sujeto + have / has not + been + forma ing del verbo principal

We have not been eating
She has not been eating


INTERROGATIVA:
Have / has + sujeto + been + forma ing del verbo principal

Have they been eating?
Has it been eating?


El Present Perfect Continuous suele referirse a una actividad que comenzó en el pasado y que todavía continúa.

She has been writing novel for the last three months
They have been having lunch for three hours
How long have they been studing?

Nota: Este uso es muy parecido al del Present Perfect Sinple con for y since.

También se emplea para acciones muy recientes cuyos efectos todavía son visibles en el momento actual.

She has been cooking. Look at my hands, they are all white with flour

Hay que recordar que hay una serie de verbos que no pueden ir en forma continua como know, believe, understand, etc.

Las expresiones temporales que lo acompañan tienen que indicar un periodo de tiempo: for, since, all day, the whole week, etc.

Nota: se suele traducir de la siguiente manera:

I have been doing a lot of work lately (he estado trabajando mucho últimamente)
They have been waiting for you for a week (llevan una semana preparando el examen)
