    How much do you know about London? Now let me tell you.

    London has about 7, 000, 000 people. About the year 1800, London was a very big city in the world.

    London is famous for many things. Tourists come from all over the world to visit its famous buildings and listen to the famous clock, Big Ben.

    Like many big cities, London has problems. there are too many cars and people. Every day about 1, 000, 000 people come and go by underground, but there are still too many cars and buses in the streets. So the air isn't clean. However, it is cleaner than it was 100 years ago.

For me, the best things in London are the parks. There are five parks in the city centre. But my children's favourite place is Hamleys, the biggest toy shop in the world.
