Translation is not only an exchange activity among languages, but also a process about transformation and communication of culture. Language and culture is a unity that language is the essential part of culture while culture is the nature and content of language communication. Because of its own history and distinctive geographical environment, culture has its unique ethnic features and psychological construction. All of these culture elements reflect on language. For different languages, there are great differences about the glyph, sound, words, rhetorical devices, and idioms. Such differences in language and culture between English and Chinese can cause the limitation of translatability in the process of translation.
