【答案解析】A Guide for Teaching Chinese Postgraduate Students English is an achievement of the important tasks in the 15th programming. I'd like to express my appreciation to the graduate department of Nanjing University. I will also especially thank my 152 graduate students who came from different departments of Nanjing University. In the past 15 years, I grew up in their generous praise and passion and they were the teachers of my young life. Because of them, I always went through every class full of passion. This book, as a souvenir for the youth time, is intended for each postgraduate student I meet.
