A Study of Culture： features, Classes, Development and Implications for ELT

引用

Sino-US English Teaching 2006年第6期3卷 44-48,52页

作者：李延林西北民族大学外国语学院

It proves to be a tough job to define culture and to draw characteristics of culture or work out the categories of culture. Based on some influential definitions, and achievements made in sociology and anthropology, this paper makes an attempt to summarize and discuss some characteristics of culture. With regard to the categorization of culture, we put forward the idea that it is closely related to the definition and features of culture, and also that it is closely related with human cognition and different perspectives, and thus culture category is an open system just as culture in general. Cultural development as product of human evolution and development is both a need and reality, going on through cultural transmission. In the process, it is human nature to encounter cultural conflicts like culture shock, the solution of which partially depends on cultural studies, on a close relationship with the main school of culture or dominating culture and on seeking similarities and accepting differences, and in a word, on friendly and cordial contacts and understanding through linguistic communication.
