The nature of the event that caused this mass extinction has been extensively studied since the 1970s. At present, several related theories are broadly supported by paleontologists:Asteroid collision Multiple collisions Environment changesdodo渡渡鳥渡渡鳥Before listening to the dodos story, try to predict in pairs how it might have become extinct.

Keys: 1 C 2 B 3 CListening textThe 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 couldnt believe it! When I asked Man directly, he seemed surprised. “I havent 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 Mans spear. He killed me too. After that there were no more dodos in the world. So my motto is: be careful who you trust. 1 a type of reptile (爬行動物爬行動物) which stopped existing about 60 000 000 years ago.
