【正文】 nversation”, and tries hard to “explain how a hearer gets from what is said to what is meant, from the level of expressed meaning to the level of implied meaning” [1] and indicates that people frequently generate conversational implicature by violating cooperative principle. So, conversational implicature is indirectly associated with linguistics content of utterances. It’s necessary for a English business trader to learn the implied meaning from what is delivered by speaker.Conversation is a most useful way for participants to deliver and obtain information. In munication, participants usually try hard to achieve the same goal or make the conversation develop to the direction as they expected. Business English conversation is a carrier of international business trade . A successful business English conversation is the result of effective team work. In order to make the munication fulfill, the participants should have one mon goal, or at least one mon direction accepted by all the participants. Usually these goals or directions are definitely set at the starting of the whole conversation[2]. For instance, two parties prepare to make an agreement of the meeting time, solve a specific problem, and then people make efforts in cooperation to realize the goals and directions.Pragmatics as a relatively new area in linguistics has already obtained great attention among linguists all over the world but there only few search in business area. By analyzing business conversations in a pragmatic approach, I hope, I can make certain contribution to correctly understand the conversational implicatures in business English conversations and help people in business English conversations and shed light on the application of pragmatics. 1. Theoretical FrameworkGrice’s conversational implicature theory and cooperative principle with its four maxims is employed as the theoretical framework to study the conversational implicature in business English conversations. A Brief Introduction to Conversational ImplicatureThe theory of conversational implicature was proposed by Oxford philosopher Herbert Paul Grice. Grice began to formulate his ideas of this theory in the 1950s, but it was known through the William James’ lectures which he delivered at Harvard in 1967. Part of the lectures was published in 1975 under the title of “Logic and Conversation”.A speaker conversationally implicates that Q by saying that P if and only if he or she is conforming to the CP in saying that P , and the explanation of his or her conformity to the CP is that he or she thinks that q, and he or she thinks that the hearer will recognize that it his or her thinking that q explains his or her conformity to the CP [3] .It has long been recognized that the onetoone relationship between its linguistic form and what a speaker truly means does not exist so that a distinction between the literal meaning of what a person says and its implied meaning is often created in daily munication. The following is an example of the conversational implicature meant by Grice:Lily: Do you have any money on you?Here, the speaker’s implied meaning is to wish the listener understand that she wants to borrow some money from the listener.So from the above example we know that the conversational implicature is a message not found in the surface meaning of the sentence, but implied in a deep level. Conversational implicature is indirectly associated with the linguistic content of utterances. So it is essential for us to learn the implied meaning from what is conveyed in some context. A Brief Introduction to Grice’s Cooperative PrincipleIn conversational exchange people usually try to reach a mon goal by mutual efforts or at least make the conversation to develop in the direction of their expectation. H. P. Grice has found some rules that apply and work in human conversation and established his theory of Conversational Implicature. Grice proposed that all speakers, regardless of their cultural background, adhere to a basic principle governing conversation which he termed the cooperative principle. That is, we assume that in a conversation the participants will cooperate with each other when making their contributions. Grice once defines the cooperative principal as following: “you’re your contribution such as is required, at the stage which it occurs, by the accepted purpose or direction of the exchange in which you are engaged[4].”People act in conversation in accordance with a general principle that they are mutually engaged in an activity that is of benefit to all, especially helpful for mutual understanding.Cooperative principle is the core of Grice’s conversational implicature. In further explaining the cooperative principle，Grice subdivides this general principle into four more detailed maxims. They are: quantity maxim, quality maxim, relation maxim and manner maxim. And the content of each maxim is as follows:The first basic maxim is the maxim of Quantity: concerned with the quantity of information to be provided and has two submaxims:Make your contribution as informative as is required (for the current purposes of the exchange).Do not make your contribution more informative than is required.The second basic maxim is the maxim of Quality: try to make your contribution one that is true and more specific:Do not say what you believe to be false.Do not say that for which you lack adequate evidence.The third basic maxim is the maxim of Relation:”be relevant”. This maxim can be interpreted as making sure what you say is relevant to the conversation at hand. The point of this maxim is that it is not sufficient for a statement to be true for it to constitute an acceptable conversational contribution. The fourth basic maxim is the maxim of Manner : be perspicuous.Avoid using obscurity and hardtounderstand words to expression。會話雙方都相信彼此說話時是相互配合的。包括商務(wù)英語談判、商務(wù)英語信函，商務(wù)英語禮儀及其他眾多方面。會話是商務(wù)運作中建立關(guān)系或達成一致的最常見的方
