    My name is Betty Sanders. I'm a telephoneoperator(话员), and work for a company. My jobis very interesting. I love it very much. I work fivedays a week, and my hours are from 9 o'clock to 5o'clock. I do a lot of things--I place long-distance(长途) calls for people; I answer questions, and Ihelp people when they are in trouble.    

    Today, for example, I had an interesting experience(经历). At 11 o'clock this morning, I got a call from a man. I didn't know who he was. He was in trouble and I could tell that hewas worried about something. He gave me an address and asked me to send an ambulance(救护车)right away. I asked him if somebody was hurt, but he didn't answer my question. He told me he needed a doctor at once, so I said I'd call an ambulance for him but I still wanted toknow what was wrong. Then he said, "Our keys are gone!" I didn't understand that! Whywould he need an ambulance just because he couldn't find his keys? Then I found out what the trouble was. The man and his wife left thecar keys on a coffee table and later theycouldn't find them. Their little boy Johnny wasplaying in the room, and they thought he hadswallowed them.      

    But before I could help him, he told me hewouldn't need an ambulance any more. His wifefound the keys in her bag. They were there allthe time.
