This book provides exercises on problem areas in English, for individual study or for group discussion. It will be found useful by teachers of English, and also by advanced learners who will benefit from open discussion of language difficulties. Teachers will find, in Discover English, a unique pedagogical approach to learners' difficulties, such as can never be found in a descriptive grammar reference book. It is a source book which teachers will want to refer back to time and again when preparing lessons, long after their initial training.
