大学英语教学的目的是培养学生的综合应用能力,适应全球化趋势下频繁的国际交流。纯粹学习语言知识而缺乏对中西方文化差异的了解,是无法进行有效交际的。教师应该在传授语言知识的同时,重视对学生文化背景知识的培养,有效提高学生跨文化交际的能力。 The purpose of college English teaching is to cultivate students’ comprehensive ability to adapt to frequent international exchanges under the trend of globalization. Purely learning the knowledge of the language and lack of understanding of the cultural differences between China and the West can not be effectively communicated. Teachers should teach language knowledge at the same time, pay attention to the cultivation of students ’cultural background knowledge, effectively improve students’ ability of intercultural communication.
