【正文】 ture is its munication system. The verbal and nonverbal symbols with which the members of a culture municate are culture bound. For example, the dominant verbal code in the United States is English whereas the dominant verbal code in Mexico is Spanish. Nonverbal code systems vary significantly across cultures. Nonverbal munication includes the use of body language, gestures, facial expressions, the voice, smell, personal and geographical space, time, and artifacts.Through symbols — whether verbal, nonverbal, or iconic — it is possible for us to municate with each other, to learn from cumulative, shared experiencs, and to pass culture on from individual to individual, group to group, and generation to generation. Culture Is the View of a Group of People Because the members of a particular culture share similar values, beliefs and behaviors, we are identifiable as a distinct group. Members of society agree about the meanings of things and about the whys. Along with everyone from whom we have learned our culture, we have interpreted life experiences in ways that validate our own culture’s views. Therefore, since we have little doubt about that validity, we all share the view that our interpretations are correct. Culture Is Subject to Change As dynamic systems, cultures can not exist in a vacuum. They are subject to change. From the wandering nomads of thousands of years ago to millions of people all watching the same news event on the Internet, cultures are constantly being confronted with ideas and information from outside sources, which have the potential to bring about changes. As a result, cultures seldom remain the same. However, what are subject to change are only some surface aspects of culture, the deep structure of a culture sustains and resists major changes. The evident and absolutely different changes in the style of dresses, food, transportation, housing and the like, must be patible with the existing value systems. Some values which are associated with ethics and morals, work and leisure, religious practices, and attitudes toward gender and age are so deeply embedded in a culture that they are usually handed on generation to generation. Communication Definitions of Communication The history of munication is as long as that of human beings. Communication appeared along with the emergence of human beings since the human survival depends on munication and contact.As the foundation of all human relationships, munication is everywhere and constantly occurs around us. However, because of its ubiquitous nature, human munication is quite difficult to define. Up to now there are as many as over 100 definitions of munication, yet no one has been universally agreed on. A variety of scholars with diverse backgrounds in the munication field have given different definitions, which, in a way, reflect how they think and theorize about munication.The most succinct definition is that munication is “the exchange of information and the transmission of meaning”. (Katz amp。 Kahn, 1996) Actually, almost all munication scholars concur that munication is a process. A process is anything that is ongoing, everchanging, and continuous during which symbols are formed and transmitted between people. Such a definition is “munication theory reflects a process point of view… you cannot talk about the beginning or the end of munication…”(Berlo).[2] . Berlo, the Process of Communication (New York: Holt, Rinehart $ Winston, 1960), .[2] A Chinese scholar Mr. Zhang Guoliang (張國良) defines munication as: “munication is the process in which one party gives the message that is received by the other party”. (Hu Wengzhong, 1999) Inextricably bound to the notion that munication is a process is the conception that munication is dynamic. Part of what makes munication a process is its dynamic nature. Bowers amp。 Bradac define it: “Communication is a transaction among symbol users in which meanings are dynamic, changing as a function of earlier usages and of changes in perceptions and metaperceptions. Common to both meanings is the motion that munication is timebound and irreversible.”(Bowers amp。 Bradac)[3] . Bowers and J. J. Bradac, “Issues in Communication Theory: A Metatheoretical Analysis,” in Communication Yearbook, , ed. M. Burgoon (New Brunswick: transaction Books, 1982), .[3]Some scholars think munication is interactive and transactive because it occurs between people. “Communication occurs when two or more people interact through the exchange of messages.”(Goss)[4] B. Goss, Communication in Everyday Life (Belmont, Calif.: Wadsworth, 1983).[4] That munication is symbolic is another fundamental assumption guiding most munication scholars. “…Communication embodies all the symbols of the mind, together with the means of conveying them through space and preserving them in time.” (Cooley)4 C. Cooley, Social Organization (New York: Scribner, 1909), p. 61. Communication is dependent on the context in which it occurs. Fisher defined it as “Communication always and inevitably occurs within some context.” (Fisher) 5 . Fisher, Interpersonal Communication: Pragmatics of Human relationships (New York: Random House, 1987), p. 22. Some scholars in the field of munication argued that it was impossible not to municate. And they believe that munication is ubiquitous, “…munication is the discriminatory response of an organism to a stimulus.”(Stevens)1 . Stevens, “Introduction: A Definition of Communication,” The Journal of the Acoustical Society of America, 22 (1950), . Nowadays more and more scholars put munication into a cultural background to research it, “…culture is munication… munication is culture.” (Hall)2 . Hall, The Silent Language (New York: Doubleday, 1959.)In its most general sense, munication refers to the share or exchange of information, ideas, feelings and so on. Or it “… is the dynamic process of encoding and decoding verbal and nonverbal messages within a defined cultural,
