On Nucleus Non-focus Function in Information Structure

调核是提示信息焦点的一种重要手段。然而,调核有时提示的不是信息焦点,而落在语用预设命题之中。语用预设命题成分是否接受调核取决于两个因素:其所指的激活状态以及与大命题之间的语用关联。决定调核的位置不是由语用预设命题的认知状态所决定的,而是由其命题所指与大命题之间的语用关联性决定的。

The establishment of the pragmatic relation is signaled by the nucleus status that can be either a focus relation or a topic relation.
