Abstract：Owing to its vividness, conciseness and humorousness, English slang has become the most active and expressive form of English language，which enjoys the great popularity among people. What’s more, nowadays books，news papers and magazines are flooded with slang. Thus with the popular and wide use in daily life，English slang has turned into an indispensable component of English vocabulary. If English learners don’t have a better understanding of slang, they can’t realize the real fascination of English language, which is crucial to slang translation. However, the translation of English slang is far from satisfaction in China. This thesis makes a study on the methods for slang translation under the guidance of functional equivalence theory so as to solve some problems arising in the slang translation.
