hello! I'm an italian student and I would ask you when I must use the past perfect continuous and when I must use the past progressive... I hope you will help me....BECAUSE I'VE NEVER UNDERSTOOD THE DIFFERENCE!!! PLEASE HELP ME!!! :-|
The present perfect progressive indicates an action that began in the past and continues into the present.
These examples are a bit more confusing:
I have been watching that new TV show. (There is an episode every week. I watched an episode in the past, liked it, and watched the next episode, then the next, and so on. I intend to watch next week's episode.)
