Abstract: Idioms, which are fixed expression formed in the process of language use, are the essence of language. There are a large number of idioms in Chinese and English languages. Idioms in both Chinese and English languages carry national characteristics and cultural information. Idioms are culture-loaded, which brings about difficulties in translating. This paper analyzed the cultural differences between Chinese and English idioms from four aspects: geographical conditions, conventions, religious beliefs, and historical allusions. And it also discussed the translation methods of idioms. It is hoped that the present study may further our understanding on idioms and may do some help for language learning and cross-culture communication. 

Key words: idiom; cultural difference; translation
