单选题Questions 19～21 are based on the following conversation.

单选题Every town in America may have a post office. Some are very small, and you may also find them in the corner of a shop. Others are large buildings. They are open five days a week and Saturday mornings. From Monday through Friday they are usually open from 8: 30 to 4: 30. If you know how much the postage for your letter, you can buy stamps from machines. Stamps are sold at many different prices, from one cent to many dollars. If you are not sure how much postage is for your letters, you can ask the clerk(职员). He or she will give you the stamps you need. If you are sending your letters far away, write on the envelope that you want them to go by air or use an air-mail envelope. Remember that postage will be more expensive for a letter you want to send overseas. At a post office you can also buy postcards. A postcard is cheaper than a letter. Usually the price of postage for a postcard is about half that of a letter. The postcards you buy at a post office do not have pictures. They are also not to be sent outside the country. Letters are an easy and cheap way to communicate(交流)with people in many different countries.
