The english grammar workbook for adults, DiGiacomo M., 2020.
This book is divided into two parts. The first part is a collection of the most practical and commonly used English grammar patterns. Each section is designed to give you a concise review of that grammar pattern, including its structure, meaning, and, most importantly, usage. At the end of each lesson, you’ll find an exercise to give you some practice. You can check your answers with the answer key at the back of the book.
