For many years people believed that the cleverest animals after man were chimpanzees. Now, however, there is proof that dolphins may be even cleverer than these big apes.
Although a dolphin lives in the sea, it is not a fish. It is a mammal. It is in many ways, therefore, like a human being（人）．
Dolphins have a simple language. They are able to talk to one another. It may be possible for man to learn how to talk to dolphins. But this will not be easy because dolphins can not hear the kind of sounds man can make. If man wants to talk to dolphins, therefore, he will have to make a third language which both he and the dolphins can understand.
Dolphins are also very friendly towards man. They often follow ships. There are many stories of dolphins guiding ships through difficult and dangerous waters.

A bag is useful and the word "bag" is useful, too. Here is an interesting phrase, "to let the cat out of the bag". In meaning it is the same as "to tell the secret". And there is an old interesting story about it.
Long ago, when farmers wanted to sell chickens at the market, they would usually just throw the chickens in cloth (布) bags. But cats were cheaper than chickens at that time, so many farmers would put cats into the cloth bags but not chickens. One day, a woman asked a man for a chicken. The man gave her a cloth bag in which there was a cat. When the man opened the cloth bag, a big black cat ran out. Not a chicken! The man's secret was out and everyone knew it.
Now when we say someone gives away a secret, we say "He lets the cat out of the bag". And that is the story where the interesting phrase came from.

Every day when Cora Castle, 14, from Indiana, US goes back home, she turns on her computer and logs into a website called Fuel Up to Play 60.
