Acknowledgments.
Writing English grammar texts is a pleasure for me. In this pursuit, I am helped by many wonderful people: dedicated teachers who give presentations at conferences and write articles for regional newsletters or international journals; researchers who explore the hows and whys of second language acquisition; grammarians who present their observations clearly and convincingly; past and present authors of other ESL/EFL grammar materials who show creative and sound approaches to helping students gain understanding and usage ability of English; colleagues who give me valuable feedback and share their pedagogical insights; and publishing professionals who know how to mold and market educational materials. We all rely on one another. Above all, I am indebted to my students, who have taught me a great deal about the language acquisition process by openly sharing with me their learning experiences and practical needs.
