The unequivalence of Chinese and English translation for advertisement and Nida s functional equivalence;

The "functional equivalence"theory to the adaptability of Chinese idiom translation;

Through the comparisons between various versions of ancient Chinese poem--《月下独酌》,the writer hopes to find how functional equivalence influences Chinese-English Translation strategies.

The most well-received equivalence theory is the one initiated by Nida, entailing dynamic equivalence and formal equivalence.

American translation theorist Eugene Nida (1964) maintains that the role of the translator in translation is an intermediary one that tries to convey to the readers the original information of the source text so as to achieve maximum"dynamic equivalence"between the source text and the target text.

A good translator should succeed in keeping the problem of "tone" in his mind and try his best to achieve a dynamic equivalence of tone between the original text and the translated text.
