Mrs. Green had a young dog which was very clever. It often helped her buy a newspaper. One winter evening, the dog went out to play. It was snowing heavily. Soon the ground(地面) became white.

     “The dog never loses his way. Where is he now?” Mrs. Green thought. She shouted(喊) his name.

    But still the dog didn't come back. So she telephoned the police and told them a lot about her dog.

    “My dog is very clever. He always goes out and comes back soon. Sometimes he plays with his friend, Mickey. He can buy a newspaper. He almost talks.”

    The policeman was tired and said, “I think you'd better put your telephone down. Maybe he is trying to telephone you now.”

    Jim, a young farmer, 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 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's a pot of 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 our fields. I can't understand it. It looks as if they were looking for something. What shall 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?

    "I have some exciting news, class," said Mrs. Pike.

    It was almost lunchtime, and Jenny Archer was hungry. She drew a piece of apple pie in her notebook. Sometimes Mrs. Pike's news wasn't very exciting.

    Once, Mrs. Pike had said it would be exciting to watch a filmstrip (幻灯影片) called Tommy Tooth and the Whole Truth about Teeth. But it wasn't.

    "We're going to have a contest(竞赛)," said Mrs. Pike.

    Jenny put down her pencil.

    "The whole school will take part," Mrs. Pike went on. "We're going to collect empty tin cans to sell. We'll use the money to buy a video camcorder and a TV monitor for' the school. "

    "What kind of contest is that?" asked Clifford Stern. "Just collecting cans?"

    "The class that collects the most cans," said Mrs. Pike, "will use the camera first. We will make our own class movie. You could all be star!"

    "Me, a movie star!" Jenny said to herself. Now, that was exciting.

    "The person in the class who brings in the most cans will direct the first movie," Mrs. Pike finished.

    Wow! Directing a movie might be even better than starring(主演) in one. The director could make up the whole story. He/She would choose the actors and tell everybody what to do. Jenny loved to make up stories. And she was good at telling people what to do.

    She was sure she'd be a great director.

    The whole class was noisy at once. She looked over at her friend Beth. Beth's eyes were bright.

    "You can be the star of my movie," Jenny whispered to her.

    "Your movie? What do you mean?" Beth asked.

    "I mean when I win the contest," Jenny said.

    "What if I win the contest?" Beth said.

    "But I have to win," answered Jenny. "I've always wanted to make a movie."

    "Since when?"

    "Well, I realised it just now," Jenny admitted. "But don't you think I will make a good director?"

    “I think I might make a good director," Beth said.

    Beth was one of Jenny's two best friends. Jenny didn't want to fight with her. But she really wanted to direct the class movie.

    "Let's not fight." Jenny said. "We will both be good directors."

    "You're right," Beth said. "We won't fight. Let's just say, may our friendship last forever. "

    Jenny shook Beth's hand. "May our friendship last forever," she repeated.
