One day Einstein( 爱 因 斯 坦 )is walking in the street in New York. His friend meets and says," Einstein, you should buy a new coat. Look!old your coat is!"
But Einstein answers," Itmatter. Nobody knows me here. "
After some years, Einstein becomes a famous scientist( 科学家 ), but he still wears the old coat.
His friend meets him again and asks him to a new one.
But Einstein says," I needn᾽t a new one. Everyoneme here. "
Every town in the United States 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 on Saturday mornings. From Monday to Friday they are usually open from 8:30 to 16:30.
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( 机器 ). Stamps are sold at many different prices, from one cent( 美分 )to many dollars. If 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. 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.
