Pretérito perfecto continuo
El pretérito perfecto continuo o "present perfect continuous" se usa para acciones que comenzaron en el pasado y siguen todavía en el presente o han acabado recientemente.
I have been watching tv for three hours
He estado viendo la tele durante tres horas
La diferencia con el present perfect es que el presente perfect continuous marca el énfasis en la acción en desarrollo, mientras que el present perfect la contempla como acabada.
I have watched tv for three hours.
He visto tele durante tres horas (ya he terminado).
I have been watching tv for three hours.
He estado viendo la tele durante tres horas (puede que siga haciéndolo y marca el énfasis en la acción, no en el resultado).
