词尾“了”的时体意义及其句法条件

This paper employs the method of experiment from classical sciences to inspect the differences between the forms of structure with ‘le’ or without ‘le’, or with various objects and subjects by adding variables into the simplest form one by one. The outcome of the inspection is “le” has concluded aspect and continued aspect, both of which implicate executed aspect. The continued aspect is implicated in action-continued and state-continued aspects. It is proved by this paper that these aspects are indicated by particle “le” together with other syntactical elements. In the meantime, I provide the simplest syntactical forms corresponding to theses aspects in this paper.
