Dear teacher, in our country there are many people who like to improve their English. They are eager to learn how to talk and make conversations possible the time the need arises. Whether they go to language institutes or do self-study, they need some books. In Iran, almost all English books are from native countries, mainly America and England. This is quite reasonable and natural because English is the language they speak; therefore, they know it better than anyone else. However, one main problem with such materials is that they do not consider the Iranian culture. They normally include subjects related to the western countries.
