五、阅读理解
Many people say dolphins are intelligent. They can learn, think, and understand things quickly. Scientists say sometimes dolphins show they are really smart, just like humans. How?
Talk
Like humans, every dolphin has its “name”. The name is a special whistle(口哨). Every dolphin chooses a whistle as(作为) its name, usually by its first birthday. Dolphins like to “talk” to each other about a lot of things—such as their age, their feelings, and danger around. Understanding dolphin’s talk is not easy for humans. No one can “speak to a dolphin” yet, but some scientists are trying to learn.
Play
Dolphins live in groups and they often join other dolphins from different groups to play games and have fun—just like people. Sometimes they run after other dolphins carrying things and throw these things back and forth. Scientists believe playing together is something only intelligent
animals do.
Teamwork
Dolphins and humans are similar(相似的) in another way: They both make plans for getting things they want. In the seas of southern Brazil, for example, dolphins use an intelligent way to get food. When there are fish near a boat, dolphins will signal(示意) to fishermen. With the dolphins' help, fishermen can catch a lot of fish. In return(回报), dolphins can get some to eat.
