For example, "I have been working for two hours."/ Another name for these tenses is the "Duration Form"./ 2.The difference between the ordinary progressive and past perfect progressive is that we use the ordinary Progressive Tenses when we only wish to express a continuous action, whilst we use the Perfect Progressive Tenses when we wish to add how long the action has been in progress 3.Consequently, we use the Perfect Progressive Tense for an action that began in the past and is still in progress, and when we wish to say how long the action has been in progress. For example: "I have been working for two hours - and I am still working."
