考题 Passage TwoTelephone 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.36. Where can you find the telephone number of a city council (市议会) in the telephone book?A. In the blue pages.B. In the white pages.C. In the yellow pages.D. In a special section.
