This book aims at helping learners of English (particularly those whose first language is Chinese) to improve their understanding of, and their competence in, English grammar. It directly addresses the needs of Chinese learners and takes full account of their first language in helping them understand how English works by systematically requiring them to think about grammar, and to come up with their own hypotheses about how it works on the basis of the givendata. The book is designed for students' learning on their own as wellas in a classroom.'--BOOK JACKET.
