Tom walked into a shop. It had a sign outside: “Second-hand (旧的）clothes bought and sold.” He was carrying an old pair of trousers and asked the owner of the shop, “How much will you give me for these?” The man looked at them and then said,“Two dollars. ”

  “What?!” said Tom. “I thought they were worth at least five dollars.”

  “No,” said the man “They aren't worth a cent more than two dollars.”

  “Well,” said Toni, taking two dollars out of his pocket. “Here's your money. These trousers were hanging outside your shop. The list price (标价）of them was six dollars and a half. But I thought that was too much money, so I wanted to find out how much they were really worth.”

    Then he walked out of the shop with the pair of trousers and disappeared before the shop owner could think of anything to say.

    Jim is a young farmer. He was once put into prison(监狱).

    One day, he got a letter from his mother. "I'm so worried about our farm, "she wrote." It's time to plant potatoes. I can't dig(挖)all the fields(田地)by myself."

    Jim read the letter and became sad. "What can I do?" he thought. Then he had a good idea. He wrote to his mother, "Don't dig the fields. There is much money in the earth. Don't plant potatoes until I come home."

    Some days later, Jim got another letter from his mother. It said, "Two days ago, about ten men came to our farm and dug all the fields. I can't understand it. It seemed that they were looking for something. What should I do?"

    Jim smiled when he read his mother's letter. He wrote a letter to his mother at once. It was very short. Guess what it would say.

    Jean is a bright young girl from a rich and famous family. She goes to a good university and has almost everything that money can buy. But all her family are so busy that they can hardly find time to be with her. In fact, Jean feels quite Lonely. So Jean spends a lot of her time on Facebook. She likes to be anonymous, using the name Linda on Facebook. She doesn't want people to know anything about her famous family and her rich life.

    Last year Jean made a very special friend on Facebook. His name was David and he lived in San Francisco. David was full of stories and jokes. He and Jean had the same interests in rock music and modern dance. So it always took them many hours to talk happily about the latest rock music and their favorite singers and sometimes they even forgot the time. Of course, they wanted to know more about each other. David sent a picture of himself: He was a tall, good-looking young man with a big, happy smile. As time went by, they became good friends and often sent cards and small things to each other.

    When Jean's father told her that he was going on a business trip to San Francisco, she asked him to let her go with him, so that she could give David a surprise for his birthday. She would take him the latest CD of their favorite rock singer. But when Jean knocked on David's door in San Francisco she found that the special friend she had chatted with on Facebook for so long was a twelve-year-old boy named Jim.
