abstract grammar
2.Based on the examination of some abstracts extracted from some important international scientific periodicals, the thesis prominently centers on the analysis of linguistic features of abstract including title and keywords in vocabulary, grammar and discourse. The writing requirements for abstract are generalized in the analysis as guidelines in writing, 5 steps, 5A strategy and ABC principles.
