Задайте 3 вопроса к тексту: With the words”Elementary, my dear Watson...” , the most famous detective of all times, Sherloc Holmes, starts to explain something to his friend., Dr.Watson. That phrase has now entered the English language. Sherlok Holmes first appeared in 1882. He became famous in “The Adventure of Sherlock Holmes”. After that came the whole series of books about him. Many thousends of books about Sherlock Holmes are still sold every year. Who invented Sherlock Holmes? Arthur Conan Doyle was his inventor. He was a doctor. In 1882 he moved from Scotland to England to set up a practice. One of the doctors he worked with, Dr. Josept Bell, was a great help to him in his detective stories. Conan Doyle started the fashion of the detective story, which goes on. And what sort of man is Sherlock Holmes? We learn a lot about him from the stories in which he appears. He is a quiet man, who only speak when he has something to say. He smokes a pipe (he has a collection of them). He plays the violin. He carries a large magnifeing glass. He lives at 221B Baker Street in London. If you go ti London, you will not be able to find 221B Baker Street. But instead, you can go to a pub called the “Sherlock Holmes”.
