Dear Sir,
I am an Assistant Professor of English and teach English in Degree classes. I have got the opportunity of going through "Advanced Learner's Degree General English" By Chowdhury and Hossain. I hope this book will serve the purpose of the students. I shall be highly obliged if you kindly send me a specimen copy of that book so that I can recommend it to my students.
