　　Business English is a vital tool for people’s international activities. It is cross-cultural language communication, which cannot be without a specific language- cultural context. General speaking, language-cultural context includes three types of environments: (1) language context, which refers to the context of an article or a conversation; (2) coexistence of the social environment of communication, namely, the words used by the speaker and listener to understand the objective environment, such as the location of business communication, the identities, statuses and relationship, backgrounds of the two sides of business; (3) their cognitive environments, that is, their different experiences, knowledge and so on. From another point of view, the context can be divided into two parts: linguistic knowledge and cultural knowledge. Many factors in culture effect understanding and expression on both sides, and will play an irreplaceable role in success in business. Though business English evolves from normal English, many words and phrases in business English are given new meanings. To accurately grasp their meanings, it is indispensable to put the words in a proper context to facilitate understanding.
