This is my first contribution since this web site has helped me a lot! About the worksheet. It is about the present perfect continuous. You can start by asking your students what has been happening in the pictures. E.g. He's been sleeping, it has been raining. Then, there is a brief explanation about the present perfect continuous and several exercises for your students to do. Besides, there are two activities taken from here that I decided to include as well. Plus, I added a song from Depeche Mode - Free love. Enjoy!
