题型：填空题
London has a population of over 7,000,000. From about the year 1800 until World War Two,
London was the biggest city in the world. But now there are many cities which are much
bigger than it.
London is famous for many things. Tourists come from all over the world to visit its famous
buildings and hear the famous clock, Big Ben.
Like many big cities, London has problems with traffic and pollution which stop the city from
developing. Over one million（百万） people a day use the London underground, but there
are still too many cars on the streets. The air isn’t clear, but it is anyhow cleaner than it was
100 years ago.
For me, the best things about London are the parks. There are five in the city center. But
my children’s favorite place is Hamleys, the biggest toy shop in the world.
