English Grammar in Context takes a building block approach by covering words, phrases, clauses, and sentence structure in its first four parts. Sections on punctuation and errors follow for easy reference and flexible use. The book is distinguished by its constant emphasis on how grammar is applied to clear writing. Helpful workbook sections for the reader are always in the context of longer pieces of discourse and show that grammar always functions in a context beyond the sentence. Each chapter begins with a pretest to allow readers to assess their own ability on a particular topic. A progression of increasingly challenging exercises follows, and each chapter concludes with a summary. Anyone interested in perfecting their grammar knowledge and usage.
