Firstly, I should say I bought this book as a resource for teaching undergraduate, non-native speakers how to give an academic presentation in English - slightly different from the book's intended purpose.
Having said that, I was, frankly, disappointed to find that the book was mainly just a series of gapfill exercises - students just look at a list of words and then write the correct one in the gaps in a series of sentences. They can listen to the correct answers on a cassette (available separately). There were a couple of other exercise types, but overall I felt the book lacked imagination, merely providing the kind of worksheet that most teachers routinely create themselves anyway. The design was also unimaginative - there was little use of pictures or colour, for example, to make the pages appear attractive.
So much more could be done to improve this material, in terms of layout, appearance, more imaginative exercises, use of authentic listening texts, the use of listening PRIOR TO gapfill, inclusion of less-controlled activities for student practice, recycling of vocabulary... the list just goes on and on.
The only reason I did not give the book one star was that it does include some relevant language which could benefit students if taught and practised appropriately. It also addresses an area (giving presentations in English) in which there is a real dearth of carefully thought-out and well-produced material. The bottom line - at most I would use this book to supplement other teaching material, but I would say that if you had the book, you would only be slightly better off than if you did not.
