When we go out for traveling, there some vehicles to choose. We can go by air, by train or by ship. When the route is long, we can go by air, because it's the fastest to go by air. We can also go by train. But it's a little bit slower. When there is river or sea, we have to go by ship. I like to go by train train because it's cheaper than by air and faster than ship. And it's also very convient.

hello,do you like traveling? you know my dream is becoming a tour guide. so i want to travel around the world. but the transportation is a problem,by air,by train or by ship?
i like perfect. i think i will choose by air. although it's so expensive, i feel comfortable.
