Americans can travel almost anywhere they choose. But to protect (保护) its people, the government lists a few dangerous places where Americans cannot go. These places are unfriendly countries or countries at war. There, the travelers might not be safe. These countries are listed in a small book called a passport (护照).

This passport is for the safety of its traveling people. It is also a government’s pledge (保证) that the people will follow the rules of the host country. To receive a passport from the government, a traveler must show that he is an American citizen (公民). An American cannot go abroad without a passport. Only the close countries such as Canada and Mexico do not ask for passports. The traveler’s picture is inside the passport. Children traveling with their parents are also in one parent’s book.
