Americans can travel almost anywhere they choose. But to protect its people，the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There，the traveler might not be safe. These countries are listed in a small book called a passport(护照).
This passport is a government request for the safety of its traveling people. It is also a government’s pledge(保证)that the people will obey the rules of the host country(东道国).
To receive a passport from the government，a traveler must prove(证明)that he is an American citizen(公民). An American cad not go overseas(外国)without a passport. Only certain close counties such as Canada and Mexico do not ask for passports.
Pasted inside the passport is the traveler’s picture. Children traveling with their parents are included in one parent’s book.
