Abstract
Different Scholars have different views of the definition of Discourse Analysis;it ’s a research method that can be used by scholars with a variety of academic and non-academic affiliations, coming from a variety of disciplines, to answer a variety of questions. Critical Discourse Analysis is a branch of Discourse Analysis; this paper introduces its development, guidance theory and approach of it. As Positive Discourse Analysis is the extension of Critical Discourse Analysis, this paper introduces the produc-tion and main theories of it. At last, a comparison was made between them.
