Phone books 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 services and public services. Businesses and professional services are listed in a special classified directory-the Yellow Pages. It is generally very easy to find a public telephone in the developed countries. Public phones are located in bus and railroad stations, airports, stores, hotels,restaurants, gasoline stations, on numerous street corners and in most office buildings. From a corner pay-call, you pick up the phone, listen for a dial tone (a buzzing sound),deposits a coin or coins (depending on the cost in the area) and then dial the number. A person-to-person call can only be accepted by the particular person you are calling. Thus, if that person is not there, you will not be charged. However,person-to-person and collect calls are more expensive than calls dialed directly because they involve the additional labor cost of an operator. The person being called pays for acollect call rather than by the person making the call. 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; or you can have the phone company mail you a credit coupon that has the same value as the phone call. 电话 |
