As everyone knows, there are many 　16　 of transportation in the world, like bicycles, buses, ships, trains and 　17　 .
If you are in big  18　like Shanghai or Beijing, maybe you get to school   19  a subway or you have to 　20　 to school because you live in a mountain village. Here I am just trying to say something about　21　 .
