 Now, here's a teaching idea for the present perfect continuous tense. If you remember, we use this tense to talk about actions that had been continuing up until the present moment or very recently. In this activity, you'll be giving a student a card. That card will include the past activity as well as some results. This card says, You've been driving in the rain on your motorbike. You're all wet and your clothes are too. The results are you're all wet and your clothes are too. You'll present that information to the rest of the class and therefore it's up to the class to guess the action that was occurring up until the certain point in time. What will happen in this activity is the student at the front of the room will express the present results. Clothes being wet. I'm all wet. The students in the group then will form their questions obviously in the present perfect continuous tense, such as have you been swimming? Have you been playing golf in the rain? The student at the front of the room will form his answers in the similar tense, no I haven't been or yes I have been. If there are troubles guessing the activity, the teacher could perhaps prompt the student in the front of the room to use a mime and they will obviously mime in this case the driving of the motorbike. Eventually the idea will be to guess that activity that again had been happening up until the certain point.
