After the Independence of our country great importance is attached in the study and teaching foreign languages. Especially after the decree of the President of the Republic of Uzbekistan on the 10th December 2012.―To develop the process of learning foreign languages‖. Not only learning foreign languages themselves but also learning their literature became important. Nowadays there are a lot of scientists, scholars, students who are interested in American literature. American literature is one of the interesting and important fields in the process of learning foreign languages. The works written by Mark Twain, Jack Jondon, Ernest Hemingway, Theodore Dreiser, William Faulkner, Upton Sinclair, and Sinclair Lewis are very popular among Uzbek readers. Sinclair Lewis was the first writer from the United States who got the Nobel Prize in Literature, which was awarded  "for his vigorous and graphic art of description and his ability to create, with wit and humor, new types of characters."  During the 1920 at  the peak of his career, Lewis managed to write about the spirit of America in his novels. “Main Street” and “Babbitt” are  presented especially about  people who are belonged to the middle class. According to James Lundquist, ―Lewis was ultimately concerned with the question of how to live in American culture of the 1920s rather than with what that culture was like.‖[1] In ―Main Street‖, ―Babbitt‖ and ―Arrowsmith‖ Lewis examines the conditions of American society and explores different possibilities for the individual to cope with those conditions.
