Can dolphins(海豚) talk? Maybe they cannot talk with words, but they can talk with sounds. They show their feelings 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(哺乳动物), not fish, but they swim together like fish in a school. Dolphins talk to the other dolphins in the school. They give information to the others. They talk when they are happy, 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. They make many more sounds under 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(水族宫). People can watch dolphins in a show. Dolphins do not 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. Dolphins’ meat is good, but people do not like to kill them. They say that dolphins bring good luck. Many people believe this.

Humans have many ways to communicate like making phone calls, writing messages, or talking face to face.
Just like humans, some insects use sound to communicate. Male crickets (蟋蟀) can “sing” by rubbing their legs on their wings. The sound is an invitation to female crickets, which says, “I’m here! Come on over!”
Bees use their sense of smell to communicate, too.
Bees also communicate in another way. After a bee finds food, it goes back to its hive and does a dance. Other bees around it can feel the dance moves.
Insects also use touch to communicate, such as ants. When an ant is following a leader, it will tap (轻拍) the leader’s legs with its antennae (触须).
A.Insects don’t have these choices. |
B.The dance’s pattern gives them directions to the food. |
C.Other insects use their sense of smell to communicate. |
D.That tells the leader that the other ants are keeping up. |
E.Ants use their antennae to communicate with their leaders. |
F.If a bee sees an enemy, it produces a pheromone that tells the other bees to attack. |
