McKay (2003) contends that culture influences language teaching in two ways:
linguistic and pedagogical. Linguistically, it affects the semantic, pragmatic, and discourse
levels of the language. Pedagogically, it influences the choice of the language materials
because cultural content of the language materials and the cultural basis of the teaching
methodology are to be taken into consideration while deciding upon the language materials.
For example, while some textbooks provide examples from the target culture, some others use
source culture materials.
