Verified Purchase(What is this?)
This review is from: Tree or Three? Student's Book and Audio CD: An Elementary Pronunciation Course (Face2face S) (Paperback)
I believe this book is the best seller in field. You can find more exercise and listening facilities for developing your pronuncation. I think this book is useful both developing pronuncation and understanding skills. Its publishing is very friendly, it is not boring, you can study as a willingly. I promise this book with intermediate level.
