A three-level series of grammar reference and practice books for teenage and young adult learners. Active Grammar Level 1 covers all the grammar taught at A1-A2 (CEF) level. The book presents grammar points in meaningful context through engaging and informative texts, followed by clear explanations and useful tips that highlight common mistakes usually made by low-level learners. Exam-style exercises provide plenty of challenging practice and encourage students to apply their ideas creatively to grammar learning. A large number of contrastive revision exercises in the book and on the CD-ROM allow students to assess and monitor their progress at regular intervals. The answer key at the back of the book makes this version ideal for self-study.
