Exploring English Information Packaging Constructions in Written and Spoken Language

摘要

Information structure refers to the relationship between sentence properties and the surrounding discourse: the legitimacy of the sentences may depend on what has been established by the immediately preceding sentences or phrases in the written and spoken language.
