کتاب English grammar in practice

English, like other languages, is full of problems for the learners. Some of these problems are easy to explain, other problems are trickier and cause difficulty even to advanced students. This written handbook is intended to help English learners to know about and avoid these problems and usage errors that occur most frequently in spoken and written English. It deals with 50 lessons with various “notice” and “watch out” boxes. Grammatical points are provided in “notice” boxes while “watch out” box contains an avoidance of a problem and correct usage of the English structure. Examples of correct usage and typical mistake below in each box enable the users to concentrate just on the point they need information about. At the end of each lesson the author attracts the students’ attention to the 10 relevant exercises through which they may spend a few minutes to practice and review the related grammatical points. We hope the learners of English will want to keep this handy book within reach to consult it whenever a specific grammatical problemarises.
