I read this article and was wondering if anyone knew of a book to use to teach this. I have several students that would benefit from this.
I would have thought that many of the holiday guidebooks and travel books contain a section on English phrases which will come in handy when travelling. Most of my little guidebooks to various countries and cities do. What sort of travel English do you want to teach them that they can't put together from the general English that you are teaching them?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
