Basic grammar in use - Raymond Murphy

Designed for high-beginner to low-intermediate level learners, this American English edition of Essential Grammar in Use focuses on the fundamental structures of English grammar normally taught in basic or introductory courses. The easy-to-use layout is inviting to learners: presentation of new structureswith examples appear on the left-hand page, and exercises to check under-standing on the right. Appendices deal with phrasal verbs, spelling and irregular verbs. The contents and index are clearly organised so that teachers and learners can easily find the unit or grammar point they need.
There is a separate answer key for individual use and self-study. The key also provides a handy reference for teachers.
