Do animals have a culture? What do we mean by “culture”? Recently social scientists have begun to ask if culture is found just in humans, or if some animals have a culture, too. When we speak of culture, we mean a way of life that a group of people have in common. Culture is the forms of behavior (行为) that help people to live together. It is also the forms of behavior that make one group of people different from another group.

Human beings use tools, cooperate(合作) with one another, and communicate with language. But these aspects(方面)of human behavior, or “culture”, can also be found in the lives of certain animals. Animals can make tools , for example. We used to think that the ability to use tools was the dividing line between human beings and other animals. Lately, however, we have found that this is not the case. Chimpanzees(黑猩猩) can not only use tools but actually make tools themselves. So it may be important for us to know that the line dividing us from animals is not as clear as we used to think.

1.According to the article, “culture” means_____.

A. the languages we learn

B. the good habits we share with each other

C. the forms of behavior we have in common

2.The traditional idea about dividing animal from human beings is that ______.

A. human beings can use tools

B. Human beings can depend on each other

C. human beings have the language to communicate

3.From the chimpanzees can use and make tools, we know____.

A. animal may have a culture like our own

B. animals can be as clever as human beings

C. animals have the ability to help human beings

A long time ago. there was an emperor. He had a beautiful garden. In the garden, there was a little nightingale(夜莺) singing very beautifully.

One day the emperor heard about this little bird's beautiful voice. He asked his guards to bring her to him. As soon as the emperor heard the nightingale's voice, he said, "Put her in a golden cage, so she can stay and sing for me whenever I want to hear her. "

The little bird was so unhappy about being kept in the cage that she stopped singing one day. The emperor was very angry. He ordered the scientists in his palace to make a robot bird for him. The bird could sing very beautifully, too. The emperor was pleased.

Soon the robot bird became old. It no longer sang beautiful songs. Just at that time, the emperor became very weak. One morning, while lying in bed, the emperor wanted it to sing once again. But the robot bird couldn't sing any more. Suddenly the nightingale landed on the window. She began to sing her most beautiful song. The emperor was very happy! He became better and better each day.
