I posted this on the Job board but it hasn't gotten replies. Since this board gets more traffic here it is again:

(Mods, feel free to delete from the Job board).

I tutor Korean businessmen here in the U.S. for a short-term English program. We're looking for an advanced textbook that has newpaper-ish articles, and also boxes with vocabulary explanations and possibly some grammar explanations. Know of any textbooks like that? These guys speak English well and read it even better- they can read Wall Street Journal articles without many problems- so the book needs to be advanced.

Thanks for the help!
