Abstract: As one of the important means of academic promotion and a unique genre，book descriptions（BD）put emphasis on both academic and social impact of certain books.Thus，book descriptions play the role of offering relevant information as well as comments of these books，so that these books are of some importance in certain fields.This study reports an analysis of book descriptions by Oxford University Press（OUP）and Foreign Language Teaching and Research Press（FLTRP）from two related angles：genre structure and lexicogrammatical features.Based on a small scale comparative study，it reveals that evaluation resources in the English and Chinese discourse present some major differences such as the process types and thematic structures.
