Why did I write this book? I have been working since 1994 as a full-time English trainer, teaching groups and individuals of all types, levels and professions. Every time I have taught a new group, I have noticed that the students always make the same mistakes which arise from literally translating into English what they would say in their own languages. This book points out these mistakes in a humorous way and is easy and fun to read unlike most "Grammar" books.
