Based on the achievement of Previous studies,this dissertation involves a research on the time structures"X+Qijian/Li/Zhong" by contrastive and interpretive methods with the analysis of corpora.And this paper also tries to giving a cognitive explanation to the difference of the time structures "X+Qijian/Li/Zhong".At first,this dissertation will analyze the lexical meanings of "Qijian/Li/Zhong" which illustrate that different lexical meanings bring great influence on the formations of "X" and the time structures "X+Qijian/Li/Zhong".In the following chapter,it will describe and analyze the formations of "X" in detail.Because of the different formations of "X",the time structures "X+Qijian/Li/Zhong" existing distinctions.As well as it will influence other usages of this structures.Next,the dissertation will compare "X+Qijian" with "X+Li","X+Qijian"with "X+Zhong" and"X+Li"with "X+Zhong" from the grammatical meanings,grammar and the usage.They still have differences even if they all can express the inside of the time.And this is why "X+Qijian/Li/Zhong" have the necessity to coexist.The influence of cognitive Psychology that closely relates to the human language expression result in the phenomenon of intertwinement among the time structures "X+Qijian" "X+Li" and "X+Zhong".Because of the cognitive customs,such as the time metaphor,time structures which have the similar meanings can substitute mutually.But they still have their respective focus because of the difference.
