关于介词“于”由先秦到汉发展变化的两种结论

Two Conclusions About the Change of the Chinese Preposition "yu " (于) From Pre - Qin (先秦) to Han (汉)

本文对介词“于／於”从先秦到汉的发展作出分析，认为，述补之间加“于／於”在先秦以前已经发展得很充分，在汉代，这种结构中间的“于／淤”已大量简省。“介词省略”说有利于进行语义分析。

By analysing the use of preposition 'yu'(于) during pre-Qin(先秦) to Han(汉), this paper holds that the use of 'yu' (于) between the predicate and complement was common before the pre - Qin(先秦) period. But the structure was often omitted in Han (汉). The theory of the 'preposition omission' helps semantic analysis.
