Dolphin Language One day Mr. Green, the science teacher, asked his class, "What do you want to be when you grow up?" "I want to be a dolphin trainer like my uncle," Mike answered. "Why do you want to be a dolphin trainer?" asked Mr. Green. "Because I'm interested in dolphin language." "Dolphin language? Tell us more." "All right," answered Mike, "My uncle tells me that dolphins are very clever. One day my uncle saw a sick dolphin in the pool. It couldn't come up for air. So it whistled to the other dolphins for help. They came to their friend and made some strange sounds. They looked sad. Then together they pushed the sick dolphin's head up above the water. Soon it got well." "Some scientists once said to my uncle, 'If you live with a dolphin and talk to it all day, maybe you can teach it some words.' My uncle decided to do that. He lived with a dolphin. The dolphin loved to play ball so he decided to teach the word 'ball' first. He threw a ball to the dolphin and said the word 'ball' many times. Soon the dolphin started to say the word." Kate asked, "How do they make sounds?" Mike didn't know. "They make sounds through blowholes in their heads," said Mr. Green. "Scientists know a little about dolphin language, but they have a lot more to learn." "That's why I want to be a dolphin trainer," said Mike. 1.注解 (1) trainer n. 训练者 (2) whistle v.
