As for the American writers, I like to read books by Mark Twain and o'henry.

He never became a rich man but at one time he was an important official in the city. William Shakespeare lived in Stratford until he was twenty-one. He got married and had three children. At the age of 21 William left for London Stratford to join a company of actors. He was a very good actor and an excellent playwright. William Shakespeare lived and worked in London for 25 years.

In all Shakespeare wrote 37 plays, 2 long poems, a sonnet cycle of 155 small pieces.
William Shakespeare had a natural gift for comedy. In his comedies «Two Gentlemen of Verona», «As you Like It», «The Twelfth Night» William Shakespeare describes the adventures of young men and women,their love, friendship, happiness.

In England and other countries it is the highest honour for an actor to be invited to play in a comedy or a tragedy by Shakespeare. In the last 35 years all the plays by W. Shakespeare have been filmed.\Since 1879 shakespeare's Festival has been held every year at Stratford-on-Avon.
