CursoLección 49/87

Presente perfecto continuó: have/has been + -ing

"have/has + been + V-ing: action started in the past, still going on or just finished with present result."

La regla

have/has + been + V-ing: acción que empezo en pasado y aún continua o acaba de terminar.

El presente perfecto continuó se forma con "have/has + been + verbo-ing". Su función principal es enfatizar la DURACION o el PROCESO de una acción que comenzo en el pasado y o bien sigue ocurriendo, o acaba de terminar con un resultado visible ahora. "I have been working all morning" implica que sigo o que acabo de terminar y se nota (cansancio, avance). Frente al simple, el continuó enfatiza el proceso, no el resultado terminado.
