Get them to prepare something before they turn up to the session. For example, they could go through an article from TIME magazine (they sound like advanced level students) and turn up with a list of things to discuss with you. Or you could get them started on a book (that you have already finished) and that would be a good discussion point during the sessions.

Otherwise, if you have a decent DVD collection, you could give them video assignments to do outside of class. I once had a series of 1-1 tutorials based around a Friends DVD box set.

I guess what I'm also saying is that a 1-1 can include all the aspects of a class - reading, listening, video work - at a stretch
