金元时期医家李东垣所作的()
【B3】
听力原文： If you plan to remain in the United States for any length of time, you will soon find it too expensive to stay in a hotel and will want to find another place to live in. As is true in cities everywhere in the world, the farther you live outside the city, generally the lower the rents will be. However, traveling to and from the city by bus, car, or train may make it as expensive as living in the city.
Naturally, it is easier to join in the life of a city if one is close to the center. For this reason, you may prefer to live as close, to the center of the city as possible. Or, you may prefer to rent a place for only a month or two until you become more familiar with the area.
Your best source of information about either houses or apartments is likely to be the local newspaper. Usually, the week's most complete listing of houses or apartments to rent appears in the Sunday newspaper, which in many cities, can be obtained late Saturday night. Many people looking for houses or apartments believe that they have a better chance of finding a place to live in if they have all the information as soon as possible. On Sunday morning, they are ready to call or visit.
