“…As a result, explicit forms must be used to indicate even the given information in the preceding example (i.e., 1 st and 2 nd person). However, as in Chinese, discourse factors do influence the choice of referential expression in English (e.g., Chafe, 1976, 1994, 1996; Huang, 1994, 1995; Levinson, 1987; Levinson, 1991). For example, less explicit forms are typically used instead of more explicit forms for previously mentioned referents ( I and you are used, rather than the speakers' names, in the preceding example).…”
