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.
Start the class off with a sentence, for example - 'I lost my wallet at the shops but fortunately ...'. Then point to a student to finish the sentence. Then continue: 'But unfortunately ...' (get the next student to finish that sentence). Continue on around the classroom. Very funny responses - my students were talking about it for a long time after.
