Learning instructions using the Air France safety video
I go to the Alliance Française and yesterday the prof showed us a video from Air France with a view to demonstrating how instructions may be given to people. This includes using the imperative, but also the infinitive, the verb 'devoir', 'Il est interdit' and very polite constructions like "We ask you to"
It's an entertaining video in French and English, with subtitles in both languages. As well as being useful to demonstrate the ways that instructions can be given I think it's useful to train your ear.
