Dolphins (海豚) are our good friends. Dolphins can make us happy. And they can also be good doctors. 

    Dolphins are very clever （聪明的）. Through some training （训练）, they can work as doctors. 它们能够帮助那些智障儿童恢复健康。It's amazing （令人惊奇的）, but true （真实的）.

    Are dolphins fish? Dolphins look like fish, but they are not fish. 和人类一样，海豚也是哺乳动物。所以，小海豚也是吃奶长大的哦！

    Let's make friends with dolphins!
