What does work to get you around unfamiliar territory (不熟悉的地方) is a map. To use a map, you must be able to read it. If you want to use a map, here’s what you should do:

　　First, find out which is north, south, east, and west.

　　Next, look for the special signs and symbols (标志物) on the map. This means you must find out what things stand for other things.

　　For example, a red line usually stands for a main highway or freeway. A black line stands for a street, and a black line with little lines across it stands for a railroad. A blue line usually stands for a river.

　　The size of cities is indicated (表示) by the size of a black dot. An airport is shown by a tiny plane.

　　All this information explaining what the lines and shapes stand for is given in the “legend.” It is called the legend because it tells the story of the map. The legend is usually found ____________ the map.

Then, of course, in order to find your way, you must know where you are first. Mark this place on the map. Then, find the place on the map where you want to go and mark it. Now you can read the map to see what seems the best way to get to your destination (目的地).
