Unit 5 Christmas every day: 'Have to' and 'must'
This unit is all about how to use 'have to' and 'must'. To help you learn the differences between them, you'll meet a British man who celebrates Christmas every day, hear about poor Aunt Jude's attempt to organise a family reunion and listen to an interview with someone who eats no meat or animal products at all. There's a also a pronunciation tip about silent letters.
