This fully-revised edition of the classic elementary pronunciation course is now accompanied by 3 Audio CDs and is suitable for both self-study and classroom use. This is a revised and updated edition of the classic pronunciation title, 'Tree or Three?'. This new edition retains many of the features that make the original edition so popular. In particular, the overall simplicity of the text and straightforward syllabus with an emphasis on minimal pairs, that makes the subject of pronunciation so accessible has been retained. Although the artwork remains simple, this new edition is in full colour to make the material more user-friendly. Still ideal for classroom use, the new edition is also more suitable for learners working on their own (at home or in self-access centres), as clearer rubrics for exercises have been included together with better overall navigation and a clear answer key. Unlike the original edition, there is no separate Teacher's Book. This pack contains the second edition of 'Tree or Three?' and a set of 3 audio CDs.
