Can dolphins talk? Maybe they can’t talk with words, but they talk with sounds. They show their feelings with sounds.
Dolphins travel in a group. We call a group of fish a “school”. They don’t study, but they travel together.
Dolphins are mammals（哺乳动物）, not fish, but they swim together in a school. Dolphins talk to the other dolphins in the school. They give information. They tell when they are happy or sad or afraid. They say“wele”when a dolphin es back to the school. They talk when they play.
They make a few sounds above water. They make many more sounds under water. People can’t hear these sounds because they are very, very high. Scientists make tapes of the sounds and study them.
Sometimes people catch a dolphin for a large aquarium.(An aquarium is a zoo for fish.) People can watch the dolphins in a show. Dolphins don’t like to be away from their school in an aquarium. They are sad and lonely.
There are many stories about dolphins. They help people. Sometimes they save somebody’s life. Dolphin meat is good, but people don’t like to kill them. They say that dolphins bring good luck. Many people believe this.
