Based on extensive research, Grammar and Beyond ensures that students study accurate information about grammar and apply it in their own speech and writing. This is the first half of Student's Book, Level 3. The Student's Book is the main component of Grammar and Beyond. In each unit, students study the grammar in a realistic text and through charts and notes informed by a billion-word corpus of authentic language. The exercises provide practice in reading, writing, listening, and speaking, making this a complete course. Students learn to avoid common mistakes, based on an extensive corpus of learner language. Each unit concludes with a Grammar for Writing section, in which students apply the grammar in an extended writing task.
