Three small fish lived in the sea. When they were very young, their parents died. They had to look after each other day after day. Finally, they grew up and could swim in deep water.

    One morning, a big wave(浪) pushed the three fish to a shallow water. It also pushed a small boat there. It was hard for them to go back to the sea because the boat was right in front of them. The largest fish realized(意识到) that they were in danger, and said they had to find a way to leave there as fast as possible. The second largest fish agreed with his elder brother, but the youngest one did not. He said that there was much time for their activities, so he would not worry at all and still swam happily.

    At last, the largest fish returned to the sea by jumping over the lowest part of the boat. The second largest fish were also successful in joining his elder brother in the other side of water. But the youngest one still swam there happily.

    Two hours later, when the sun came up, the water in the small shallow part dried up(干). The youngest fish died finally.

    Once there was a parrot on sale in a pet store. It was a beautiful red and blue bird. It sat on a perch in the middle of the store, so that everyone could see it when they came in. The owner was very proud（自豪的） of it and asked a high price for it.

    One day a man went into the store. “That's a beautiful bird,” he said to the pet store owner, “But why is it so expensive? Is it unusual（不同寻常的） bird?” “No, it's not very unusual. It's expensive because it can talk,” the pet store owner said.

    “I see. How can I make it talk?” the man asked.

    The pet store owner asked him, “Do you see those string tied to each of the bird's legs?”

    “Yes,” the man answered.

    “Well, you pull（拉） those strings（绳子）,” the pet store owner told him. “That will make the parrot talk.”

    The man asked, “Do you mind（介意） if I try?”

    “Not at all,” the pet store owner said.

    The man walked up to the parrot and pulled the string on its left leg. The parrot said, “Good morning.” The man pulled the string on the parrot's right leg. This time the parrot said, “How are you today?”

    “That's not very interesting,” said the man. “Any parrot could do that.” Then he laughed, “But what would happen if I pulled both strings at the same time?”

    “I'll fall off my perch, you fool!” the parrot said.

    Yesterday the police were joined by more than 20 volunteers in the continuing search for the two missing teenagers, Vicky Gray and Tom Hunter, and their guide, Gavin Jones. The police said that they had disappeared during an adventure tour of Cape York Peninsula.

    This was the second day of the search and the police were now very worried about the safety of the three missing people.

    The police said that the search had covered a wide area, but the rain forest was thick and their work was made harder by the recent rain. Later on Chief Inspector (警官) Roger Fleet said, “The travellers had a radio with them. If they had been in trouble, they would have called us.”

    The three travellers left Cooktown very early on Saturday morning in a Toyota car. They took a small dirt road that runs down to the Daintree River, a dangerous river full of crocodiles (鳄鱼). Chief Inspector Roger Fleet said the tourists wouldn't have got into trouble if they had stayed on the main road.

    A photo of Vicky and Tom was found by a policeman under the “Be Careful about crocodiles” sign near the river. Why was the photo left behind? This is just one of the unanswered questions. Other questions are: Why was the photo left behind? Why was the Toyota parked and locked at the edge of the rain forest? The police said that the travellers had left a map of the area behind. Why? Why had someone drawn a cross on the point where the car is? Is this a sign? What does it mean? If anyone can give information or has seen these three young people, contact the local police in Cooktown.

    Angelo Casimiro made something new at the age of fifteen.

    Casimiro made a device(装置）. It can charge（给……充电）your cellphone as you walk! When you run, jump or walk, a pair of discs(唱片）inside the shoes can produce electricity. It can be used to charge your phone or any other devices with a USB port!

    People have to move a lot if they use the device to charge. Those who like travelling in the wild will love it. It takes about eight hours' jogging to charge a lithium-ion（锂离子）battery and two hours' playing basketball will only give the cellphone about 10 minutes' charge.

    A device called SolePower is a kind of insole（鞋垫）that can produce electricity. SolePower is like Casimiro's device, but it can fully charge a cellphone after over a four-kilometre walk. So there's a lot for Casimiro to do to make his invention（发明）better.

    Anyway, Casimiro's device is quite good. After all, his invention started something new, right?
