Present Perfect Continuous
This time you need to make the present perfect continuous question forms - it could be a 'wh' or 'yes / no' question.
It's really important to make sure you are confident making the forms of the tenses, so then you can focus on when to use them, which is a bit more difficult. Even some of my advanced students aren't really 100% sure about the forms, and this really shows if you need to speak English in a hurry or during exams when you are stressed.
