“It's just a story,”you may think. But new research has found that crows' brains may sometimes be better than those of 6-year-old children.

In a recent experiment, American scientist Corina Logan and her team caught six crows to test them. The crows and children had to choose between two sets of tubes(试管). They had to drop stones in and get water.

With the red set, when they dropped a stone into a wide tube, the water level raised in a connected narrow tube. The blue set of tubes, however, had no connection between them.

Children aged 7 to 10 were able to learn the rule. Children aged 4-6, however, failed.Five of the six crows failed the test. But Kitty, a 6-month-old crow, passed it. She put most of the stones into the red tubes.

So, could a bird be more clever than a kindergartner? Don't be too quick to say no.

    Captain Nemo seemed very sure that that savages could not harm us. I slept well. When I went outside the next morning, I saw that there were many more natives on the beach. It was low tide, and many of them had come quite close to the Nautilus. I asked Conseil to get a net, and we used it to get some shells from the water. They were very pretty shells. Suddenly, I saw a very rare and beautiful shell. We looked at it together. One of the savages threw a stone at us and broke the shell. Conseil was very angry. He fired his gun at the savage. Then, we noticed that the savages had come very close to the Nautilus in their canoes. A few moments later, they began to shoot their arrows at us. We went inside and told Captain Nemo about it. He ordered his men to close the doors.

    “But what will happen tomorrow?” I asked. “You will have to open the doors to get more air, and the savages will come in.”

    “Do you think they will dare?”

    “I am sure they will.”

    “We have nothing to fear,” he said again.

    Captain Nemo asked me about our trip to the island. I told him what we had seen and done. We talked about another French sailor called D'Urville, whose ship was wrecked in the Torres Strait. He told me again that the high tide the next day would lift the Nautilus off the reef.（选自《海底两万里》）

    Hi, I'm Dino, the family dog. I help keep people safe, especially on the roads. Take a look at my diary to see what I did last week.

    Sunday

    Some children are really too young to take care of themselves. Our neighbor's boy ran in front of a car to get his ball. The car almost hit him. I saved him though. Remember, always look and listen.

    Tuesday

    People can get very angry when driving, usually for silly reasons. One driver started shouting at Mum today when she stopped to let some children cross the road. I soon made the driver stop.

    Wednesday

    One thing makes me really mad. Grrrrrr. People walk on a dangerous road when they can walk on the safe pavement (人行道). I saw two girls doing that today but I soon made them change their minds.

    Saturday

    Today Mum took me for a walk. One car was parked in a very dangerous place. It was right on the corner of the street. Don't worry though. I left him a message.
