One day, a mother crocodile (鳄鱼) and a baby crocodile swam slowly in a river. Suddenly, the mother crocodile saw a monkey, "Oh, a monkey! How nice if I have it for dinner!"
"My son, can you go and get the monkey for me? I want to eat his heart (心脏)," the mother crocodile said.
"All right," the baby crocodile answered.
The baby crocodile swam near the river bank (岸). He shouted at the monkey, “Hey, monkey！Would you like some bananas? There are many banana trees on the other bank of the river"
"I likethemvery much. But I can't swim. How can I get there?" the monkey asked.
"Oh, I can take you there," the baby crocodile said.
"Really? Thank you very much!" the monkey jumped onto the baby crocodile's back. In the middle of the river, the baby crocodile went into the water.When he came up again, the monkey was wet all over."Don't do that again, or you'll kill (杀死) me!" the monkey shouted.
"I know, but I must do that! My mother wants to eat your heart."
"My heart?你为什么不早点告诉我?I left it in a tree. We should go back for it!" So_ they went back.
As soon as they got to the bank, the monkey picked up a big stone (石头) and climbed up onto the tree quickly. He shouted at the baby crocodile, "Don't you want my heart? Well, catch!" The monkey threw the big stone at the crocodile.
