ABSTRACT
One of the most pressing problems in my work is the culture of communication. We all know that language and culture are interrelated. Communication is not only vocabulary, grammar and pronunciation, but also cultural aspects of this language. There is much more common side between English and Uzbek culture, but we still see the opposite. Language represents the nature of the country - its people, its emotions and traditions. That is why a foreign language teacher should teach the same language to the community. The relationship between language and culture is a complex one and it is always quite challenging to fully understand people’s cognitive processes when they communicate. Language competence does not only include the knowledge of grammatical principles and sentence construction, but also knowledge of the norms that link language to social and cognitive context. Many teachers and students seem to lose sight of the fact that knowledge of grammatical systems has to be complemented with culture-specific meanings.
The structure of a language can determine the way
