The study reviewed the achievement of theoretical and practical study on time metaphor in the past decades.

This paper is an attempt to make a reanalysis of duality in time metaphor from the perspectives of cognitive science,semantics and culture for the purpose of exploring the complexity of time metaphor.

Because of the cognitive customs,such as the time metaphor,time structures which have the similar meanings can substitute mutually.

Human body is the cognitive prototypical model of spatial metaphor, and the experience of the body is the base of metaphorical concepts.

Taking "up -down" structure in Chinese as example, this paper compares the corresponding English spatial structure to find out the differences and similarities in forms and meanings of spatial metaphor from the three aspects of state, status, quantity, revealing the cognitive habits behind spatial relations.

The theoretical basis is that metaphor is an important means of experience the world and spatial concept is mainly expressed by means of metaphor——spatial metaphor which is a kind of image schema.

There exists intersubjectivity between the addressee and the addresser in the process of metaphor interpretation, which guarantees the realization of intermetaphoricity.

There are two systems for time as space metaphor: moving-time metaphor and moving-ego metaphor.

The new discipline studies the features,formation and development of regional cultures from unique perspectives of which space metaphor becomes an important approach.

First,the paper discusses the issue from the perspective of temporal metaphor,and then applies Antu?ano s hypothesis of property selection process and Boers s theory of parameter of variation to explain this phenomenon in details.

These temporal metaphors also have their own traits—at the lexical level time is expressed variously: (1) time words in minority languages are more transparent in morphemic motivation than those i.
