Touchstone is an innovative four-level series for adults and young adults, taking students from beginning to intermediate levels (CEFR: A1 - B2). Based on research into the Cambridge English Corpus, Touchstone teaches English as it is really used. It presents natural language in authentic contexts, and explicitly develops conversation strategies so learners speak with fluency and confidence. New in the Second Edition: • extra grammar practice focuses on key grammar points in each unit; • can-do statements help students understand the learning outcomes of each lesson and rate their own performance; • common error information from the Cambridge Learner Corpus helps students avoid making basic errors; • sounds right activities provide regular pronunciation practice and enable students to speak with confidence.
