Ahmad Sharifzadeh, a trilingual lecturer, author, translator, and editor, has written a book on Academic English Grammar for Intermediate and Advanced Learners. The book is a middle ground between Chomsky's syntactic structure and traditional grammar books. It focuses on syntactic structures and is less abstract than Chomsky's work. The book is based on years of teaching experience to university students from different majors at different proficiency levels and is intended to help students comprehend and produce the English language better.
