This is one of two books of exercises designed to accompany Thomson and Martinet`s "Practical English Grammar". They provide intermediate learners with a wealth of interesting and lively practice material, concentrating on those areas of grammar which generally cause most difficulty. The books may be used alongside the "Grammar" or on their own, with or without a teacher, and are particularly useful for revision. Answers are printed at the end of each book. For this third edition some changes have been made in the text to bring it up to date and five new exercises have been added, making a total for both books of 190. The exercises now follow the same sequence as the chapters in the "Grammar" and they have all been graded. References are to the fourth (1986) edition of the "Grammar".
