Abstract
The English language is more widely used around the world than ever before, More and more people are using it in business, industry ,politics, education, and various professions. The more widely English is used the greater is the need to teach ,the greater is the need to train teachers to teach it .Ideally, of course, trained native speakers of English would make the best teachers of English; but the supply of native English speakers can't possibly meet thegrowing demand for teachers of English,and more and more non-native speakers are being trained to teach English as a foreign language. Languages are studied by more people than ever before and materials of teaching them are changing radically. The goals of the literature have broadened to include spoken communication with an understanding of native speakers of the widest range of human interests. In attempting to explain the great movement and change in the methods of teaching foreign language, we will take communication approach in language teaching as an example explaining and giving the readers some detailed information in hand and why this approach emerged and what this approach focused on in teaching foreign language.
