Review title: Good concept, but lacks a glossary
Product review: This book has a solid approach of linking grammar topics with communication functions. The book does a good job of showing the particular real-life contexts in which the various structures can be used. In addition, the explanations are straightforward, non-technical, and clear.The fatal flaw, however, is that the book lacks both vocabulary lists in the units and a glossary at the end of the book. I think that this book might still be useful as a supplementary resource, but it can definitely not serve as a primary self-instructional course.
