For example, it is the metaphor GOOD IS UP that makes "good" plus "up" form top-grade, the metaphor BAD IS DOWN that makes "low" plus "bad" form inferior.4. Based on the weakness of Lakoffian conceptual theory in interpreting spatial metaphors, we propose an interpreting means-metaphorical force, which is much easier to make clear how metaphors are formed between two domains.Based on Lakoffian conceptual metaphor theory and through analyzing Chinese spatial metaphors and their metaphorical extensions, we put forward with an interpreting method-metaphorical force. By applying the interpreting means to analyze Chinese spatial terms used in temporal representations as well as in Chinese appellations, we conclude that such interpreting method is a persuadable explaining theory and an able analyzing method to describe working mechanism of metaphor.
