     Mrs Smith is the owner of a house. She keeps one room for herself and rents the other rooms. Since

her house is near a college, many students want to rent her rooms.

     Now Mrs Smith has to be careful about the use of the phone, water, and everything else, because she

worries that the renters (租房人) will keep the bill (账) high. Last month's phone bill was very high. She

wants to know if someone in the house makes long distance (长途) calls and doesn't tell her. So she decided

to find out who it was.

     She has waited behind the door for several nights. Just now she was glad to hear someone coming near

the telephone desk. She couldn't hear what the person was saying, but she was sure it was a man's voice.

hide something. She went to the room quickly so that she could catch the man right then.

     But when she suddenly opened the door, she saw only the back of a man with his hand on the telephone

desk. He was saying something in a low voice to a girl beside him. So Mrs Smith still doesn't know who made
