Concering The Position Of Directional Complements And Objects In View Of Cognition

Based on a comprehensive investigation,analysis and description.I try to find that the position of the object of the verb with a complement of direction is conditioned by varied factors,such as the nature of the verb,the existence or absence of "了"(le),the complement and the object,and sometimes the context.the paper gives a detailed description of the rules that govern the position of the object.and attempts to explain why the objects of directional complments have to be followed by“来”(lai)/“去”(qu),not the other way around.the reason why the object can have three different positions when it refers to a concrete thing is discussed.as well as the semantic difference between the three.
