| My holiday is coming. Yesterday I asked my American friends about the best way to travel within the United States. They said it was best to go 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 to one who wants to see the 4 . Besides, airfare 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, my friends tell me, is easy, cheap and convenient, though not so fast as traveling by plane or so 8 by train. You can find buses almost in every city, big or small. That makes travel arrangement easy. I take their 9 . Now I have decided to go to the east coast with an interesting 10 by bus. | |||
