It is commonly believed that English is becoming a widely used language, and through it, one can participate in a variety of social activities, because language is more than simply a way of expression, it helps people form relationships and know how to interact in different social contexts depending on sociolinguistic situations. English is one of the most important languages of the world. As stated by Baugh (2002), it is spoken by more than 380 million people in the United Kingdom, the United States, and the former British Empire. It is the largest of the Western languages. Many people are aware of the value that the English language has in today's world. For that reason, the demands for learning it are increasing every day. There are different factors which make that language dominant and important; some people see it as their window to the outside world in the sense that they can use it as a medium of communication with others from different countries because it is widely spread. Others believe that through that language they can check recent researches and read books from other countries so it represents for them a source of knowledge. It is widely recognized that the English language is becoming an effective means to communicate, to participate in international business activities, and to obtain information about the events all around the world. In her book "Teaching English Overseas", Mckay (1992) demonstrates that the reason for the widespread of English is the belief that a certain proficiency in that language may provide social and economic gains.
