With the analysis of the conceptual dimensions of time metaphor representation, it summed up that the archetype of time metaphor is space-time metaphor.

The paper explored the psychological mechanism of space-time metaphor by two experiments.

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 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.
