    Traveling is very interesting. Many people love traveling. There are many ways to travel: by plane, by train, by ship or by car. Everyone has their favorite way.

    Greg: My favorite way of traveling is by car. I can bring my pet dog along. I can travel three hundred miles or only fifty miles a day. I can stop at a good restaurant to enjoy a good meal or at a hotel to spend the night.

    Eliza: I love traveling by train best! It's very exciting. I traveled most of Europe in 5 months by train. It's the best way to talk with the local (当地的) people and make new friends on the way. Trains make even the longest trip enjoyable. The train ride to me is just like a big moving party.

    I also like traveling by ship. It is a very great way to spend a vacation. I can go to parties and movies on the ship, and enjoy the blue sky and water.

    Danny: Planes are my favorite. It's the fastest way of traveling. I can quickly get to another country. Planes have very comfortable seats. I can have something to drink and to eat. I can also read some free magazines and newspapers.

— Yes, and it's also _________.

    My holiday is coming. Yesterday I asked my American friends about the best way to travel around the United States. They said it was best to travel by 1 and gave me the 2.

    To fly, of course, is the fastest way, but one can't see anything during a 3 except the blue sky and white clouds. So it is not very interesting for one who wants to see the 4.Besides, the plane ticket is very 5.

    To travel by train is 6, because passengers can walk and buy food and drinks on a train. They can also see cities and the country through the windows. But trains don't leave or 7 at a place every day, and don't go to many cities.

    To travel by bus is easy, cheap and convenient, though not so fast as travelling by plane or so 8 as by train. You can find buses almost in every city. That makes travel arrangement easy.

    I take their 9.Now I have decided to go on an interesting 10 by bus to the east coast.
