…although my only source for that is the Daily Mail, which might well mean that it’s been completely made up (rather than just slightly rewritten from PR press releases like many Guardian “articles”). Still, an interesting topic.
I highly recommend children’s literature and TV programmes for adults learning foreign languages. You will pick up some odd vocab and the surrealism can make you think that you’re not understanding the story even when you are, but they are a lot more motivating than content designed for language learners like graded readers. The language can also be much more memorable, be it because of the amount of repetition or because the memorable situations also make the language stick. If you choose older content, it can also help you learn exactly the kind of cultural knowledge that all native speakers share but language learners rarely catch up on.
Don’t know if anyone else has recommended Manolito Gafotas for Scott Thornbury’s quest to improve his fossilised Spanish, but was the best of all sources for me.
