As an important component of the speech system, the status of discourse markers in language research can't be ignored. Discourse markers (often abbreviated as DMs) are a kind of explicit oriented markers in the process of discourse communication, which play a vital role in the generation and understanding of discourse. As a discourse marker, “well” has a number of textual functions; it gives indications of textual problems or regarding the structure of the text. Most often it is used in my data when the speaker has difficulties expressing him/herself and is searching for the right phrase.
