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.
Ask the class to work in groups. Each group thinks of a famous story they all know - e.g. a fairy story such as Red Riding Hood or a film such as Star Wars. Ask each group to think through the story and imagine what warnings they could give the characters at various points in the story: e.g. 'If you meet a wolf - run!', or 'If you can't see your granny - phone the police!'.
When ready, pairs of groups meet and say only their warnings; the other group must guess what the original story was. When both groups have heard all the warnings they should invent a completely new story for which ALL the warnings apply!
