《新概念英语》第三册第一课 A Puma at Large

There are more than two hundred animals in the zoo. One day last summer, a puma got out of its cage and jumped over the wall of its enclosure. It landed in the road outside and quickly disappeared. The keepers had not even seen it, so they did not know that it had escaped. Some people in a car saw it, however, and were very frightened. They drove away quickly. The puma wandered through the streets of the small town, where the zoo was situated. People stayed indoors, and children were warned not to go out alone. The police were telephoned, and for the whole of that day, the town was in a state of great excitement. Shopkeepers locked their doors, and men with guns and dogs searched the streets. But the puma was not seen again.
