第9题
In 1979 almost 15 million American held passports. Most of these passports were obtained to travel outside the country because, except for a few Western nations, passports are required to enter every country.
And if you travel abroad, you must have a valid passport to return the country. When traveling abroad, you will need a passport for identification when exchanging dollars for francs or marks or other foreign currency. You may also need your passport to use a credit card, buy an airplane ticket or check into a hotel. As a passport is an official U.S. document, it is valuable as identification in any emergency overseas, such as floods, fires or war.
Don’t confuse passports and visas. Whereas a passport is issued by a country to its citizens, a visa is official permission to visit a country granted by the government of that country. For some years, many countries were dropping their visa requirements, but that trend has reversed. They may be obtained from the embassy of the country you wish to visit.
Passport applications are available at passport agency offices in large cities like Boston, New Y ork, or Chicago. In smaller cities, applications are available at post offices and at federal courts. To get your first passport, you must submit the application in person, along with a birth certificate and two pictures.

A.discuss traveling in other countries

C.discuss the financial uses of a passport
D.provide information about passports
Passports are beneficial for___________.A.exchanging currency
B.using a credit card

D.all of the above
We can conclude from the passage that_________.A.passports are more important than visas
B.visas and passports are the same thing
C.foreign government issue visas instead of passports

The passage suggests that_________.A.Most people don’t realize how important passports are
