prepose

The past research on the subject focuses on the macro-functions of preposing in discourse and few studies have touched upon its micro-functions.

以往研究局限于前置句型在语篇中功能,其微功能很探讨。

From the point of view of the informativeness and textual cohesiveness of preposed theme, the stronger its informativeness, the weaker its cohesiveness, and vice versa.

从前置主位和衔接来看，前置主位所传递新越弱，其语篇衔接越强，反之亦然。
