Jack is in bed. Mr. Smith sits beside him.

    “What kind of day do you have today?” Mr. Smith asks.

    “It is a bad day for me,” Jack answers. “I have a fight with Tom. Then the teacher calls you and tells you about it, right?”

    “Yes , part(部分) of the day is bad,” Mr. Smith says. But there are good parts, too. Now it is time to go to sleep. So tell me the best thing to you today.

    Jack is happy and he says, “After school, I go swimming. I make a new friend in the swimming pool.”

“I am happy you have a good time,” Mr. Smith says. “Think about it before you go to sleep. Now I'm going to turn off the light(关灯). Have a nice dream!”

    “Good night, Dad,” Jack says.

    Every night Mr. Smith and Jack have a talk like this.

    Every night Jack answers the same question, “What is the best thing to you today?

    Every night Jack goes to sleep thinking about the best thing. It's really a good way to end(结束) a day.”

    One of the most detailed(详细的) descriptions Of a UEO was given by nine-year-old Gaynor in Sunderland in July 1976.

    Gaynor lived in Oakenholt, a village in North Wales. On her way home from school, she saw a silver(银色的) object shaped like a saucer(茶碟) in a field not far from her home.

    The strange craft(飞行物) was about 30 feet long and 9 feet high. It had yellow windows along the side and on the top there was a light flashing in a kind of box. Although Gaynor was very frightened, she did not run away. Instead, she lay quietly in the long grass and watched the door of the strange craft open. She saw two people wearing silver suits come out of the craft. They were carrying some kind of equipment(设备) which they used to examine the ground.  They were short and had large pink eyes, Gaynor reported.

    After about half an hour, the two people went back into the craft. At once there was a loud noise and the UFO took off.

    Although Gaynor told her mother what she had seen, her family decided to keep quiet about it. They did not want people to laugh at their daughter. However, 18 months later, Gaynor told her story to UFO experts. They hypnotized(使进入睡眠状态) Gaynor so that they could be sure she was telling the truth.

    Not only did she repeat her story, but also she was able to draw a picture of what she had seen!

    The story of Robinson Crusoe is known all over the world. The story is about the life of a real person. His name was Alexander Selkirk.

    Selkirk was born in 1676 in Scotland. His father made shoes and clothes, but Alexander didn't want to work in his father's shop. He wanted to sail a ship on the sea.

    When Selkirk was 28 years old, he was sailing on the Pacific Ocean. The ship was in a bad state. Selkirk was worried. "This ship is not safe!" he thought. He told the captain that he wanted to get off. The captain didn't like Selkirk, so he agreed. The ship took Selkirk to a small island.

    Selkirk took a few things from the ship: a gun, an axe, and a few clothes. Then the ship left, and Selkirk was alone. There were no people or houses on the island. He was more than 600 kilometres from the nearest country, Chile.

    He found a cave near the beach and this became his home for the first few months. In the day time, he had to leave the cave and find some food. He usually ate fish and other small sea animals. At night, he heard strange noises from the trees. He thought that there were wild animals on the island that could hurt him. He was afraid and didn't want to leave for the beach. He stayed in his cave. He was very lonely.

    One day, when he woke up，he saw hundreds of sea lions on the beach. He couldn't get to the sea, so he couldn't catch any fish. He had to look for food on another part of the island. He was still afraid of the wild animals, but he was hungry! He had to go out in order not to be hungry.
