阅读理解。 One difference from the other cities is that London has two centres: the City of London, the centre of business, and Westminster, the centre of the official offices. The City of London is in fact a small area and only about 5,000 people live there but it is the centre of British business. The City of Westminster not only has the Houses of Parliament (议院) but also the different official offices which control the country. Other famous areas are the West End and the East End. The West End is the part that visitors usually see because it has many famous shops, such as Selfridges and Simpsons, and many museums such as the National Art Building and the Museum of Mankind. Most of the big London theatres and cinemas are also in the West End. The East End has always been poor and not interesting but the home of the true Londoner, the 'Cockney'. People say that a Cockney has to be born within the sound of Bow Bells: this means that he could hear the sound of the bells in a church (教堂) in Bow, a place of the East End. The East End used to have the docks (船坞) and some factories but now the docks and many of the factories have moved out of London. London is now a mixture of peoples who came from many countries but are now just Londoners. Many people came from the old British colonies (殖民地). But there are also large groups of people from Poland, from Italy, from France, and from many other countries. Now you can buy food from any country and hear any language spoken in London. The only difficulty is finding a restaurant where you can eat English food. 1.
