Suitable for classroom use or self-study, Active Grammar presents and practises grammar in clear, realistic contexts specially chosen to appeal to teenage and young adult learners. The series covers all the grammar points taught at A1-C2 (CEF) levels. Each unit opens with an original text followed by clear explanations of the key grammar points. Engaging presentations help students learn about the world while they study English grammar, and a large number of contrasting revision exercises help to develop students' command of several grammar points at once and to prepare them for communication outside the classroom. Regular tip boxes give information about common mistakes and the accompanying CD-ROM contains additional exam-style exercises and tests for more grammar practice.
