Preface Advanced Written Grammar is a versatile and comprehensive aid in learning grammar, punctuation, mechanics, and diction. Intensifying the basics of written Standard English grammar, it is a workbook of exercises, and a convenient reference handbook, an intermediate to advanced level writing text for academically bound ESL and EFL students. One central point which should emerge through a student’s careful use of this text is that the study of grammar and sentence elements is a practical means of improving communication and understanding. In this book, we give explanations of the most important, frequent, and typical points of English grammar along with a lot of practice material so that you can put the knowledge to use immediately. The exercise helps you to link the meanings and structures.
