I have been exposed to this book since 2002,but I did not read these articles in the book at first.I just regarded it as listening materials while I 've gotten familiar with vocabulary at the end of each passage.Later on,I do not read this book thoroughly until I can listen everything freely to some extent.From the point of view of vocabulary and grammar I work hard and take paticipation in training courses.
