One of the nice things about the city of Washington, D.C., the capital of the United States, is that it has a number of large museums. People who live there can visit one of the fine national museums many times during the year. Although some exhibits are permanent, there are also many special travelling exhibits which are only shown for a short period of time. The entrance fees are not expensive, and they have special rates for groups. So if you like art, natural sciences, technology, American Indian history, or just want to take a walk inside a nice clean air-conditioned museum at a reasonable price, museum visiting is one of the best pastimes. 【題組】
