London has a population of about 7, 000, 000. It lies on the River Thames, where the Romans landed nearly 2, 000 years ago. From about 1800 until World War Ⅱ, London was 1 city in the world, but now there are many cities which are much bigger.
London is famous for many things. Tourists come from all over the world to visit its historic buildings, such as Buckingham Palace, where the Queen lives, and the Houses of Parliament(国会大厦), where you can see and 2 the famous clock, Big Ben. They also come to visit its theatres, its museums, and its many 3 , such as Harrods, where you can buy anything. And of course they want to ride on the London Eye next to the river.
Like many big cities, London has 4 with traffic and pollution. Over 1, 000, 000 people a day use the London Underground. People who want to 5 into the city centre pay Congestion Charge, which cots 8 pounds a day, but there are still too many cars on the streets. The air isn't clean but it is cleaner than it was 100 years ago.
For me, the 6 thing about London is the park. There are five in the city centre. But my children's favourite place is Hamleys, which is the biggest toy shop in the world.
