    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.

    This passport is a government request for the safety of its travelling people. It is also a government's

pledge (保证) that the people will obey the rules of the host country.

    To receive a passport from the government, a traveler must prove that he is an American citizen (公民).

An American cannot go abroad without a passport. Only certain close countries such as Canada and Mexico

do not ask for passports.
