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 package includes both Student's Book, Level 4, and Class Audio, Level 4. In each unit of the Student's Book, learners study the grammar in a realistic text and through corpus-informed charts and notes. The exercises provide practice in reading, writing, listening, and speaking. Students learn to avoid common mistakes, based on a corpus of learner language. Each unit concludes with a Grammar for Writing section, in which students apply the grammar in an extended writing task. This Class Audio CD includes all of the audio for the exercises in Student's Book, Level 4.
