Today，for example，I had an interesting experience（经历）.At 11 o’clock this morning，I got a call from a man. I don’t know who he was. He was in trouble and I could tell that he was worried about something. He gave me 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 to know what was wrong. Then he said，“Our keys are gone!” I didn’t understand that! Why would 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 the car keys on a coffee table，and later they couldn’t find them. Their little boy Johnny was playing in the room，and they thought he swallowed（吞下）them.

But before I could help him，he told me he wouldn’t need an ambulance anymore. His wife found the keys in her bag. They were there all the time.
