　　Every town in the United Sates has 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(邮资) is for your letter, you can buy stamps at any window. In some post offices you can buy stamps from machines. Stamps are sold at many different prices, from one cent(美分) to many dollars. 1f you are not sure how much postage is for your letter, you may ask the man or the woman in the post office for help. He or she will give you the stamps you need. If you are sending your letters far away, you should use airmail envelopes(航空信封). Remember that postage will be more expensive for a letter to be sent outside the country.

　　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 that you buy at a post office do not have pictures. However, also they are not to be sent outside the country.

　　Letters are an easy and cheap way to keep in touch with people in many different countries.

本文介绍了两种不同对待儿童应用计算机的观点，前者认为弊多，后者认为利多．究竟哪种观点对，请阅读下文．

　　We are already familiar with computers-computers work for us at home, in offices and in factories. But it is also true that children today are using computers at school before they can write. What does this mean for the future? Are these children lucky or not?

　　Many people who do not know about computers think of them as machines that children play with. They worry that children do not learn from experience but just from pressing a button and that this is not good for them. They think children are growing up not knowing about the real world.

　　But people who understand more about computers see that computers can be very good for children. A computer can help them to learn about the real world more quickly, to learn what they want to learn and to think for themselves. And for the future, don't we need people who can think clearly, who know how to get information quickly and use it well?
