I hate to be negative, but this book was truly a waste of money. The activities are not useful to actual business executives learning English- entire units on "calling and making a hotel reservation", "talking to people at a trade show", etc. They have even laid out the book where you can't even use it without the classroom CD for the majority of the exercises. I didn't know this when I purchased the book, and the CD, of course, costs more than the book! I have never encountered a good Business ESL text. I think I need to produce one myself!
