Abstract:
 As we enter the new millennium, because of economic development, contact with people from various cultures is increasing. International scientific cooperation is at an all-time high. International trade and tourism is an increasingly common phenomenon. When we interact with someone from a different culture, language plays an important role in communication. We are well aware that different cultures use different languages and dialects, and differences in languages make communication more difficult. In any case, to expect the nonverbal behaviors of other cultures to match ours is unrealistic. Norms and interpretations of nonverbal behavior vary tremendously from culture to culture.
  Nonverbal messages serve multiple functions in international interaction. While verbal messages convey content meaning, nonverbal message carry strong identity and relational meaning. Nonverbal messages can help to emphasize (repeat), complement, substitute, regulate, and even contradict the meaning of the verbal messages. While verbal messages are digital in nature, nonverbal messages are analogic in form. The use of verbal messages involves human intention, while the use of nonverbal messages can be intentional or unintentional. So, nonverbal communication is very important for us to make communication in cross-culture intercourse.

Key words: culture; intercultural communication; nonverbal behavior; difference

摘要：
在新的世纪里，由于经济的发展，科技的交流，世界贸易及国际旅游业的不断拓宽，不同文化之间的交流更密切。当我们与来自异文化的人进行交流时，如果我们不懂对方的语言，交流是不可能的。因为不同的文化有不同的语言。在跨文化的非语言交际中，我们常常会遇到非语言行为意义的差异。在任何情况下，都不能完全期望异文化的非语言行为与本土文化的意义一致，文化的不同导致非语言行为的标准及意义的差别。
  在跨文化交际中，非语言行为所提供的信息是不容忽视的。语言信息提供的是一种文字的意义，而非语言信息提供了强烈的个性特征和相关文化信息。非语言信息对语言信息起到加强（重复），补充，替代，调整，有时甚至是一种否定的作用。语言信息是一种天然的数字符号，非语言信息在形式上具有类比性。语言信息的使用表达人类的行为目的，而非语言信息具有目的性和非目的性两重属性。因此，非语言交际对我们进行跨文化交流是非常重要的。

1 Introduction
There are two systems in human communication: verbal communication and nonverbal communication. Verbal communication consists of word language and the variations in meaning which a person puts into words through the way they are said.We all know verbal communication is arguably the most important of all human behaviors, but we often ignore the other way. In fact, nonverbal communication is the foundation of human relationships. Some anthropologists believe that more than two-thirds of any communication is transmitted at a nonverbal level. A famous professor Edward Twitchell Hall has ever said: “ What people do is frequently more important than what they say.”.
