A) Notting Hill is located a few kilometers northwest of Trafnigar Square near Hyde Park. It is an affluent and faahionable area of the city. Attractions in Notting Hill include the Portobello Market. The community wan the location for the 1999 Hollywood movie entitled 'Notting Hill" which starred Julia Roberta and Hugh Grant. There are a number of fine hotels and restaurants in the Notting Hill district of London.

B) The East End is a well-known district of London which especially famous as the centre of clothing industry and for centuries people from abroad have come to find work there. Traditionally someone born in the East End is known as a cockney although this name is now given to anyone who speaks like a Londoner. Typically they change certain vowel sounds and have a few problems with 'th' and use 'f' instead.

C) Soho is a famous area of the City of Westminster, part of the West End of London. The area was developed from farmland by Henry VIII in 1536, when it became a royal park. Some scientists think that the name 'Soho' first appears in the 17th century. The name may possibly derive from a former hunting cry. James Scott, Ist Duke of Monmouth, used "sobo' as a rallying call for his men nt the Battle of Sedgemoor on 6 July 1685, half a century after the name was first used for this area of London.

D) The Royal Opera House, or Covent Garden as it is usually known, is located in the district of the same name, not far from one of the most famous of London streets. A visitor of London is always surprised when he sees the Opera house standing almost inside the flower and vegetable market which gives a distinct smell to the whole quarter. Now Covent Garden is one of the few well-known opera houses open for eleven months of the year and it employs over 600 people both of the Opera Company and the Royal Ballet.

E) Many of the shows which go on the West End are light comedies, but some theatres put on more serious plays. One of England's leading companies is the Royal Shakespeare Company. There they put on new and old plays, and some Shakespearian plays. The National Theatre is also a well-known London's theatre worldwide. The building is modern, and the plays are classics and new productions.
