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能,其微能很探讨。

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.

从前置主位性和衔接性来看，前置主位所传递新性越弱，其语篇衔接性越强，反之亦然。
