单项选择题
Telephone books in the United States
have white, blue and yellow pages. The white pages list people with phones
by last name, the blue pages contain numbers of city services, government
agencies and public schools. Businesses and professional (专业的) services
are listed in a special section, the yellow pages. To make a long-distance
call, you need an area code. Each area in the U. S. has an area code. The
area covered by one area code may be small or large. For example, New York
City has one area code, but so does the whole state of Oregon. If you want to
know the area code of a place, you can look it up in the area code map, which is
printed in the front of the white pages. There are a lot of publlic telephones in the US. They have their own numbers. If you are making a long-distance call on a pubic telephone and run out of money, give the number on you phone to the person you are talking to, then hang up the receiver, and he can call you back. If you make a long-distance call and get a wrong number, call the operator and explain what happened. This means that you can make the call again to the right number without having to pay more money. |
