C
New York City is a very large city with 8 million people. How do so many people move on their way to work and school?
In New York you can travel around the city by subway, bus, taxi and car. The subway train runs on the railway lines under the city. It crosses the city at different points and goes to all parts of the city. Travelling by subway is the fastest way to get around the city.
The second way to travel around the city is by bus. It is a slower way to travel. This is because the bus moves on the road on which traffic is often heavy.
You can also travel around the city by taxi. This is very expensive, but the taxi will take you to 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". This is the time when the traffic is very heavy with people going to and from work.
The last way to get around New York is using your own car. It is inconvenient(不方便的) since you will perhaps be 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 a. m.to 4 p. m. This is the time after the morning rush hour and before the afternoon rush hour. Traffic will be less crowded during this time since most people are already at school or at work.
