Language and culture are closely related with each other: language is the carrier and a fundamental part of culture, while culture has an intrinsic and indispensable impact on language and is also reflected in language. So if in the language learning and teaching, attention is only paid to the linguistic forms but the relationship between language and culture is ignored, then the learner’s linguistic ability will not be equivalent to his or her social and cultural communication competence. Especially in the times of globalization with increasing transna tional and cross-cultural communication, the knowledge of cultural background is the must prerequisite for not only the avoidance of cul tural "conflict" but the success of communication. Based on the studies of several cross-cultural communication cases and the analysis of the relationship between language and culture, including the famous Sapir-Whorf hypothesis, this paper is aimed to analyze the intrinsic and in dispensable relationship between language learning and culture learning.
