The languages are not only tools in understanding,communication and thinking, but also one element of the cultures. Thinking is a kind of abstract skill, and the language is the vehicle of thinking, through which people can understand the human beings＇ thinking methods and cultural characters. The languages are decided by the culture. Reading comprehension is the readers＇ own behavior, during which the schema plays a key role and readers must combine the new information with their former cultural knowledge, rebuilding the new information so as to understand the deep meanings of the articles.展开更多
