Prior research on capital structure by Titman (1988) utilizes structural equation models to find out the determinants of capital structure. In this paper, we use the same methodology and add another endogenous variable – stock return to construct two equations. One regards capital structure and the other one regards stock returns.

The second part, we analyze the aspect mark in contemporary Chinese. Under the classification of the modality of the verbs and the functional grammar, the transformational generative grammar, we classify the aspect into two types: typical and non-typical. Each is then divided into six. And the non-typical one is representedby result complement verb phrase and reduplicative verbs.
