Hey, how do I download it?
This is a warmer, and there is nothing to download. It's just an idea for your lesson, not a worksheet.
Students should try to provide as many different excuses as possible to explain why the person calling them cannot speak to the person s/he wants to. Example: "He is having dinner" or "She is walking her dog", or "They are flying to Madrid in 5 minutes". This activity can also be used for present and/ or future uses of Present Continuous.
