Dan and Kim are friends. Dan lives in an apartment downtown(市中心). It is very convenient to go to work or go shopping, but it's too noisy. There is a lot of traffic. Sometimes Dan can't stand(忍受). Kim has a house in the suburbs(郊区). It's not convenient to go to work or go shopping, but it's very quiet. There is not much to do. In fact, nothing ever happens.

    Dan and Kim have a good idea. They decide to trade(决定交换)places one week.

    An old man visits a new doctor. He is very young. "I don't fed well, doctor." he said. "Please find out what's wrong with me." "Take off your clothes and lay down on the bed." The old man takes off his clothes and lies down on the bed. The young doctor examines him. However, he can't find anything wrong with the old man. He listens to his heart. He looks into his throat. He examined every part of him. At last, he says, "I'm sorry, but I can't find anything wrong with you." "That's strange." the old man says, "I feel really bad."

    "Go home and come to see me again tomorrow, if you don't feel better." the doctor says, "I'll examine you again." "All right, doctor." the old man says slowly. He stands up and puts on his clothes. Then he walks out of the hospital. A few seconds later, the nurse runs in. "Doctor, doctor!" she cries, "That man you said was healthy has just died outside of the door." The doctor thinks quickly. "Turn the body around, so that people will think he was coming in." he said.
