Before listening to the dodo’s
story, try to predict in pairs
how it might have become
Listen to the tape and choose the sentence on page 30 which gives the main idea of the story:
This story is about how the dodo became extinct.
No 1 is wrong. It is not fair to blame the dodo for his disappearance. No 3 only explains half the story. The dodo and man did become friends but only because man wanted to kill the dodos as easily as possible. No 4 is wrong because the other animals and birds did not do much to save the dodo. They warned him but did not help him.
Listen to the tape and choose the correct answer to complete each sentence on page 30. Keys: 1 C 2B 3C
The story of the dodo Once upon a time I lived on the island of Mauritius. I was called “dodo”. There were many of us and we were friends with all the other animals on the island. One day a new animal came to my island. His name was Man, and at first we seemed to be good friends. We went
everywhere together and I shared my food with him. However, I began to wonder why several of my dodo friends had disappeared. Then the number of our species began to decrease quickly. I was so worried that I asked the other animals and they all told me, “Your friends are being killed and eaten by Man while you are hunting for food.” Had Man eaten them? I couldn’t believe it!
When I asked Man directly, he seemed surprised. “I haven’t seen the other dodos either.” he said. “Maybe someone else killed them.” I believed him but when more dodos disappeared I set a trap. I went off as if I was going to hunt but instead I hid in the forest and waited.
Sure enough Man came along. He ran after the last of my dodo friends and killed her. I felt so angry that I rushed out of my hiding place and straight at Man’s spear. He killed me too. After that there were no more dodos in the world. So my motto is: be careful who you trust.
