Market Leader 3rd Edition Elementary Coursebook & DVD-Rom Pack: Industrial Ecology Paperback – 19 July 2012

This is an excellent book at a very good price, since it includes all the audio and videos as well. It's very useful for adult EFL teaching even outside a business context, since it is aimed at adults, and really covers adult vocabulary and situations, which makes a big change from other "elementary adult courses" which I find are suitable for ages 13 to 18 rather than adults.

simple and great
