  Many people like to travel by plane,but I don't like it because an airport is usually far from the city.

  You 1       get there early and wait for hours for the plane 2        and it is often late. You can't open the window. You can't 3        the food. And it also takes hours to get out of the airport and into the city.

  I like traveling by train. I think trains are 4       . Railway stations are usually in cities. When you are late for a train,you can 5        another one. You can walk around on the train. You 6       can see many interesting things on your way. I know it takes a little 7        time.

  I also likes cars. You can start your trip 8        you want to,and you don't need to get to a railway station 9       a bus stop. Also you can carry many things with you in a car. But sometimes there are 10        cars on the roads.
