Six people were travelling on a train. Five of them were quiet and polite, but the sixth was not. He was always making a lot of trouble. At last this young man got out at a station carrying two heavy bags. None of the other travellers helped him, but one of them waited until the young man was very far away, and then opened the window and shouted to him. "You left something on the train." Then he closed the window again. The young man turned around and hurried back. He shouted through the window, "What did I leave behind?" The train began to move again. The traveller opened the window and said "A very bad impression(印象) ."

    Sammy Liu, a six-year-old boy from Kowloon, has become a hero recently. One day he used the family's 1 to stop a robbery. While the thief was very busy searching the flat, Sammy went into his bedroom 2 and used his computer to call the police, who arrived in five minutes and caught the thief.

    These days, it is 3 for children as young as Sammy to be so good at computers. Many children use computers at home or at school and some schools 4 have their own websites. Such websites not only offer students the opportunity to learn new skills but also mean that people all over the world can find out more about their schools.

    Some parents think that spending too much time using a computer can be 5, but there is the opposite of it. "Kids should be encouraged to use computers as early as possible," said Tony Robertson, a software developer.

    Whether at home or school, the digital age(数码时代) has certainly opened the 6 to a whole new world of learning.

    Every day on Amelia's way to work she had to pass a slum(贫民窟) .Though she was a social worker, she had never paid much attention to it.

    This changed when she met a boy named Jack. Jack knew that she was the head of social services, and was sure she could help. He reached out his hand to touch her, and said, "Can you help me? I'm looking hard for my dad."

    His hands were so cold that Amelia could not help holding them. She said, "What's up? ""My mum is sick and too weak to get up. Her birthday is coming. I know my father's coming back would be the best present. We really love him, and need him." "So what's his name? What does he do?" Amelia asked. He said, "I've no idea. My mum said he had left us before I was two years old." Amelia was deeply moved and said, "Take me to your home, son."

    He led her to a small house. Looking around, there was nothing in it except for a small bed. A woman was sitting on it and as soon as Amelia saw her, she knew her life was near its end. She said to Amelia, "Please find a home for my son. Please don't leave him alone in the world. "With tears running from her eyes, Amelia took her hand and said," I will take care of him and love him as my own son." In fact, since her husband and she had no children, they had been wanting a child for a long time.

    Ever since Amelia took Jack into her home, life is full of joy and laughter. She got the best present in return for her kindness.

    In 1947, an American pilot said that when he was flying in the sky he had seen nine strange things. They looked like saucers. Then n reported his story. After that, more people all over the world said they had seen strange things. But people could not decide on what the things were or w they came from. So they c them UFOs.

    In 1973, two f said that when they were fishing by a river they had seen a UFO. It looked like an egg. There were three f like men in it. They had no eyes and their mouths were long and narrow. Their noses and ears were strange too.

    p some people made a mistake, but pilots and astronauts do not usually make mistakes of this kind. Captain Ed Mitchell, the sixth man to walk on the Moon, said in 1974 that he had seen some flying saucers. He said these flying things were perhaps visiting the Earth from other worlds in space.

    There are many stories about UFOs. However, n knows whether they are true or not.

He me about it.
