1.   说出你认为对你最有用的一本书，并解释原因。

The most important book for me is my undergraduate major textbook which is called marketing. Because as we all know that marketing is a kind of major which cuts across the boundaries of many different disciplines, so it broadens my knowledge scope, such as the aspects of advertising and trade. On the other hand, well, a plenty of cases are included in this book, in addition, many definitions can explained very acceptable so it definitely helps me to get a deeply understanding of my major.
