Attributive clauses in EST often consist of complex structures and deliver a multiplicity of meanings. It will be one of challenges facing the translators to transfer the attributive clauses in EST faithfully, completely and smoothly into Chinese so that the understanding and response of the target language readers to the information produced in the translation are almost the same as that of the original language readers to the information contained in the original attributive clauses in EST, thus achieving functional equivalence of the translation. Under the direction of Nida's functional equivalence theory, this paper is dedicated to discussing the translation techniques of EST attributive clauses, and hope it benefits the translation of EST in the future.
