     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.

    Car Free Day encourages drivers to give up their cars for a day to protect the environment. People from around the world get together in the streets to remind the world that we don't have to accept the society full of cars. It was first started by 34 cities in France and September 22 is Car Free Day. The first Car Free Day in China was in Chengdu in 2001. The slogan for the day is "If we drive for one less day, we can have one more nice day."

    Organized activities are held in many cities on Car Free Day. In Brussels, Car Free Day shall be valid (有效的) for everybody except persons with a special permit(许可证), but they have to slow down to the speed of 30 kilometers per hour. The public transportation is free on that day. In London, they have special "green areas". Walking, biking and public transportation are encouraged. The streets are open only to walkers, bicycles and buses from 7: 00 a. m. to 7: 00 p. m. In Beijing, it asks drivers to leave their cars at home for one day each month and walk or ride a bike to work. More and more people are joining in the activity. In the first quarter of this year, Beijing only had 52 blue sky days, and you may see haze(雾霾) almost every day! We must do more for Car Free Day as a Beijing driver said, "We may not change the weather, but we can choose not to drive."

    But we do not want just one day and then a return to "normal" life. We should go on with Car Free Day.
