Can dolphins talk？Maybe they cannot talk with words，but they can talk with sounds.
   Dolphins travel in a group.We call a group of fish a "school".They do not study but they travel together.Dolphins are mammals（哺乳動(dòng)物），not fish，but they swim together like fish in a school.Dolphins talk to other dolphins in the school.They give information to the others.They talk when they are happy or sad or afraid.They say "welcome" when a dolphin comes back to the school.They talk when they play.They make some sounds above water.People cannot hear these sounds because they are very，very high.Scientists make tapes of the sounds and study them.Sometimes people catch dolphins for a large aquarium（水族宮）.People can watch the dolphins in a show.
   Dolphins don't like to be away from their school.They are sad and lonely in the aquarium.Here are many stories about dolphins.They help people.Sometimes they save somebody's life.Dolphins' meat is good but people do not like to kill them.They say that dolphins bring good luck.Many people believe this.
