Impact Grammar
Grammar through Listening

Designed with the same spice and full-color brilliance as Impact Issues (see Conversation: Listening/Speaking section), this book is just for students who want to improve their knowledge of English grammar! The trendy student book comes with an audio CD for classroom use or self-study. Each of the 50 two-page units contains five carefully sequenced exercises organized by levels of difficulty. The grammar points reflect the most commonly made errors.
Features listening tasks (passages are on the 70-minute audio CD), concise grammar explanations, grammar presentations in context, diagnostic self-tests, an answer key, and tapescripts.
