London is a very large city with about 7 million people. How do so many people move on their way to work or school?

In London you can travel around the city by subway, bus, taxi or private (私人的)car. The subway runs under the city. It goes to all parts of the city. Traveling by subway is the fastest way to get around the city.

The second way to travel about the city is by bus. It is a slower way to travel. This is because the road traffic is always heavy.

You can also travel around the city by taxi. This is very expensive, but the taxi will take you to the every place you wish to go to. If traffic is heavy, the taxi will be slow. During the mornings and afternoons, there is the “rush hour”.

The last way to get around London is using your own car. It is inconvenient(不方便的) if you are driving in the “rush hour”. If there is an accident on the road, you will have to wait for a long time.

The best time to travel around the city is from 9 am to 4 pm. This is the time after the morning “rush hour” and before the evening “rush hour”. Traffic will be less heavy during this time.
