This book has many things going for it. The lessons are simple and direct. The exercises constantly repeat what has been formerly taught. New ideas are approached incrementally in digestible form. The nature of the exercises forces the students to use what they have learned. In particular this is true with the formula sentences the students are required to produce almost immediately. This book is different. Yes, it is a lot of work, but there is no such thing as a free lunch in learning how to write. The total focus in this book is on the sentence. Grammar is a means, not an end.
