Grammar for English Language Teachers helps teachers to develop their overall knowledge and understanding of English grammar, and provides a quick source of reference in planning lessons and clarifying learners' problems. Each chapter includes a Typical difficulties section, which explores learners' problems and mistakes. The book encourages teachers to appreciate the range of factors which affect grammatical choices, but also introduces the 'rules of thumb' presented to learners in course materials. The Consolidation exercises provide an opportunity for teachers to test the rules against real language use and to evaluate classroom and reference materials. The book is organised thematically, but also provides a 'short cut ' index at the beginning for ease of reference. There is also a Cambridge ELT website with further chapter-by-chapter extension exercises to accompany the book.
