Abstract: Genre analysis is a key technique for studying article abstracts. In terms of genre analysis theory for the corpus of 50 English abstracts and 50 Chinese ones of aerospace articles, this paper conducts a contrast study of respective moves of their macro-structures. This paper also studies language features of English abstracts and discusses the differences within English versions of Chinese abstracts. The results illustrate the five-move abstract which contains background, purpose, method, result and conclusion, and demonstrate the language features of English abstracts and the differences between Chinese academic culture and western academic culture, which give insights into the building of our present academic culture.
