9.3.2.1 Formación del present perfect continuous

La lógica siempre es la misma. Se forman los tiempos continuos con el verbo to be. En el caso del present perfect continuous se usa el present perfect del verbo to be. En el capítulo 8.3.1 explicamos cómo se forma el present perfect.

Ejemplos     

to have been    
= present perfect
+ verbo pleno
 + sufijo -ing = present perfect continuous
He has been do ing He has been doing
She has been writ(e) ing She has been writing
We have been jump ing We have been jumping
They have been sell ing They have been selling
You have been study ing You have been studying
I have been watch ing I have been watching

La construcción siempre es la misma en todos los tiempos.

I am doing.
I was doing.
I have been doing.
I had been doing.

Se forma el tiempo continuo con la forma de to be que corresponde y el present participle.
