                                              How "Kangaroo" Became an Animal's Name

     Early in the 18th century, Captain Cook, a famous explorer (探险家) of Australia, unexpectedly caught

sight of an unusual animal dunng his first visit to Australia. The animal had a large mouth-like head and jumped

along on its large legs. To his great surprise, the unusual animal carried its young in a special pocket of flesh.

Captain Cook pointed to the animal which was eating grass in the distance and asked his native guide what the

animal was referred to. The guide seemed not to know what he was pointing at and finally said Kangaroo,

which Cook carefully wrote down as the animal's name in his word book. The Europeans who later got to

Australia were anxious to see the unusual animal "Kangaroo", but their requests were met with puzzled looks

of the native people. Before long they got to discover that the native guide who made the answer to Cook's

question really meant, "I don't know what you are pointing at." Funny enough, the name "Kangaroo" stuck

and it is still in use today.
