Summary: Deepen ceaselessly as what reform and open to the outside world, the each respect communication of China and global other country and area and cooperation are closer and closer. Join WTO, chinese market will be opened further, course of study of movie and TV is facing unprecedented development opportunity, also facing a challenge at the same time. As a result of the difference of thing square culture, a lot of English terms in film interpreter are like metaphrase, can make broad China audience cannot be accepted with self-identity. In addition, the film translates text to accept the restriction of time of movie picture switch, cannot learn work like interpreter article in that way, some of explanatory note can be made in a few obscure and difficult part, so the translation of movie dialogue must let an audience listen, look to be able to be understood namely. Translator should base oneself upon at native audience, the artistic point of view that appreciates appreciation dubbed film from the audience sets out, choose this ethical signal call the turn and former an art is the most similar, most of press close to, be familiar with for native audience place, the term that accepts easily and culture image will undertake the film is translated. Keyword: Teleology; Movie dialogue; 　 of interpreter process 　 one, teleology of interpreter of 　 of functional theory 　 is interpreter of German function clique a kind of when Hans Vermeer learning the home and Katherina Reiss found seventies in 20 centuries new translation is academic mode. Vermeer broke through the limitation of quits theory, put forward to be interpreter criterion with text purpose, put the interpreter in behavior theory and the frame that cross culture intercourse to undertake making an on-the-spot investigation, think to translate and not be the changeover that is a foundation simply with original text version, be opposite in the purpose however a kind of information of source culture is delivered, it is a kind of intercourse action that steps culture. Any interpreter action are decided by the interpreter's purpose, in short, translate a purpose to decide to translate a method namely, want to be able to achieve the interpreter's goal only, right textual the method that can use literal word-for-word translation already, also can use the method that adapts completely, perhaps use mind at both any interpreters between are politic, the first principle that this is this theory -- purpose principle. What it emphasizes is " suit " , and rather than " quits " . In translating a process, translator must adopt some kind of means to make sure translation uses the play of the function in the environment in its, the ask and presses the person that use apiration that makes sure translation accords with the person that use starts its function, and the object of translation -- one of the mainest factors that the reader is decision interpreter purpose. The culture setting with reader peculiar place, interpreter act that reads the element such as need to affecting translator. Translator should set out with the reader's angle, choose proper interpreter method and strategy, the much source that provides from textual place undertakes alternative interpreter in information, in order to achieve the interpreter's goal. Translating additionally two principles that teleology place follows is inside language coherent with language border coherent. Inside language coherent (namely consistent law) the cultural background that is the person that show translator should consider to accept and actual condition, translation must accord with interpret to enter the expressive habit of language, can let translation reader understand and significant in purpose language culture and the intercourse environment of use translation. And faithful law is to point to to some kind of quits relation should exist between translation discourse and textual discourse, nord thinks, depend on to textual dutiful degree and form the purpose of translation and translator are right textual understanding (Nord, 1997: 85) . In these 3 law, faithful law is subject to consistent law, and consistent law and faithful law are obedient at aim rule. This theory broke through equivalence to translate talked set pattern, on the start person that projected the look interpret is made, translator and body of the person that accept, gifted the meaning with interpreter new more, have very great economic sense and direct sense to the interpreter. The article aims to use teleology, will analyse the interpreter method of dialogue of movie and TV. 2, the 　 of characteristic 　 　 of language of movie and TV (one) the language in drama of movie and TV of instant sex 　 is phonic language, written in water, because of this general requirement audience can understand. (2) afore-mentioned diagnostic place that this is language of movie and TV decide masses sex 　 . Art of movie and TV is destined since birth day is the art of a kind of in a popular style. Besides the work that seldom counts experimental sex, great majority film and teleplay are viewed and admire for people. Accordingly the language of drama of movie and TV must accord with the educational level of wide audience, the requirement can listen to understand. In the meantime, the instant sex of this and language of movie and TV also is contacted. The property of the property that movie and TV translates, principle and itself of art of skill movie and TV decided movie and TV translates the interpreter that understands written language with general necessarily to differ somewhat. This kind of distinction reflects the basic in principle that is translating above all. The instant sex that movie and TV translates and masses sex set however, interpreter of movie and TV must be a center with purpose language audience, take care of their language level appropriately. The method that this nature means movie and TV to translate is the method that gives priority to with free translation. This is Nai amounts to what what advocate " the function is quits " . (Nida And Taber: 　 of 1969) 　 (3) concise change, spoken language changes language of 　 movie and TV to speak with the character more or the form of inner monologize or aside appears, namely very spoken language is changed. Be based on these bright characteristics of language of movie and TV, translator is translating his into another country when the character, have to consider the issue passing interpret of language color, in order to make the movie audience of his country experiences the glamour to film language adequately, can enter because of interpret otherwise of language obscure and difficult, affected lose major viewer. 3, movie and TV is translated " purpose " 　 of interpreter process 　 can be seen by next graphs, interpreter of this kind of caption has two interpreters arrangement. The first administrative levels is by textual data give somebody a new lease on life (Original Text Creation) , grass translates a data (Transadaptation) , translation (this process comprises Translation) . The 2nd administrative levels is by textual give somebody a new lease on life (Original Text Creation) , translation (Translation) 　 the first, measure is the interactive communication that points to author and translator. Translator needs to be setting language with source language, the with the interpreter information when be being gotten through coming to the analysis of source language and explanation is conveyed. The 2nd measure is the interactive communication of translator and audience. In this measure, translator must be setting language with target language, through be in compose is built with the explanation, will convey an audience with accurate eye catchphrase people the canto that is fond of Wen Ledao comes. The 3rd measure is the first measure is mixed directly of the 2nd measure amalgamative. Translator is in the bridge action in the 3rd measure. No matter be ground floor or the 2nd interpreter process,be one kind aeriform. Translator should be jumping-off place with the purpose of reader audience, otherwise interpreter of the caption in this is without a meaning. A case is cited below, " escape from prison " in have a word: Preparation Can Only Take You So Far. (Wang Yawen, when 2007) 　 is translating this sentence, translator must consider factor of etc of associated, importance, later from ground floor second if undertaking be translatinged this, will search translation area the data into grass (the measure of Transadaptation) . To implement this measure, meaning person can do a few metaphrase enough. Grass turns over a data to may be become " preparative action is finite " . However, what did after seeing this translated text as the audience, total meeting feeling lack, can have a place sometimes cannot the implication that instantaneous understands this sentence to fall in whole words condition. Translator is about to be setting language to turn over a data to undertake words condition is analysed to grass with Chinese at this moment, undertake to whole sentence new form is built. Consider this sentence to want expression in film " preparation is insufficient " , a lot of other factors try hard in what affecting them. So, through measure B, meaning person can translate for " plan matters is in person, accomplish sth is in day " . This is a general Chinese idiom, concise and comprehensive, can let person instantaneous quickly understand the meaning that hero place conveys again. Thereby recreational masses, service popular purpose was achieved. When translator undertakes an interpreter, have a problem that must want to notice, that is humorous to the foreign country China changes an interpreter. In the film " in law politics mad shark " , having a word is such: I Swear To God! In most person this very easy interpreter, can translate into " I pledge to god! " but combine the words condition at that time, and the expression of the hero and movement, apparent this is a camera lens that lets audience laugh. The interpreter above is a kind of metaphrase apparently, of very inaccessible laugh letting a person. Actually, this achieves grass to reverse the move of the data namely, had not arrived at the measure of translation truly. Just as its name implies, humorous in interpreter of movie and TV action is to make person laugh, to achieve this one goal, this one can be translated into " I assure to Chairman Mao! " the speech that this is a commonly used in the Great Cultural Revolution acceptance. And looking nowadays is laughingstock. And the interpreter's purpose also was achieved mix former the same intention that place of movie and TV should express. 4, anyhow of epilogue 　 　 , aim of specific activity of interpreter of dialogue of movie and TV is to endeavor to deliver movie and TV piece language and culture information, realize movie and TV better piece aesthetic value and commercial value, the attraction with the oldest rate audience. Dialogue of movie and TV translates mobile purpose to depend on satisfying the need of the widest audience, will analysed as it happens to satisfy this respect to need; with teleology at the same time, from macroscopical on look, this one purpose also is to promote the culture communication between different language, different people and shirt-sleeve purpose photograph to agree together.
