I have a student interested in having just conversation lessons. He studies English grammar and vocabulary independently, but wants to have conversation lessons once a week to improve his listening, conversation skills, and pronunciation. I was wondering if anyone out there could recommend a good conversation coursebook that they've used. I know that some books exist, but have yet to find one that is appropriate. My student is a 40 year old business man, interested in improving his English conversation skills (he is at the intermediate level) in a wide variety of general situations, not just business. I really appreciate it if you could give me some advice! I am really at a loss as to what to do!
