A group of students at Sunshine School are holding a charity sale to raise money to help their classmate Lisa. Lisa had cerebral palsy (大脑性瘫痪) when she was a baby. People who have cerebral palsy have trouble walking. Although Lisa has to use a wheelchair (轮椅) to help her get around, she never gives up.

    "Lisa has the chance of standing up, but she needs an operation (手术)," Lisa's doctor said.

    "I never thought that I could stand up one day. Actually the news is surprising for me. However, when I see my parents are worried about the cost of the operation, I am sad. I don't mind if I can't stand up," Lisa said. "Now my classmates and some other kind people are helping me. I am really thankful."

    "While helping Lisa, we can also learn a lot. We have learned how to cook cookies (曲奇饼) and how to sell them," Betty, one of Lisa's classmates said. "Now we know making money is not easy, so we won't waste money anymore."

    Alex, a boy in Lisa's class, told a reporter that they could raise about $100 every day. "We have raised about $2,100 so far. We hope we will raise more money for Lisa's operation," he said.

    Today, roller-skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, no one had any ideas of roller-skating. That changed because of a man named Joseph Merlin. He liked to make things and play the violin in his free time. He was a man of ideas and dreams. People called him a dreamer.

    One day Merlin was invited to a party. He was very pleased and a little excited. As the day of the party came near, Merlin began to think how to make an amazing entrance at the party. He had an idea. He thought everyone at the party would show much interest if he could skate into the room. He tried different ways to make himself roll. Finally, he decided to put two wheels under each shoe. These were the first roller skates. Merlin was very proud of his invention and dreamed of arriving at the party on wheels while playing the violin.

    On the night of the party Merlin rolled into the room playing his violin. Everyone was very surprised to see him. There was just one problem: Merlin had no way to stop his roller skates. He rolled on and on. Suddenly he ran into a mirror that was hanging on the wall. The mirror fell down, breaking into pieces. Merlin's idea was so good that nobody forgot his special entrance for a long time. But could he find out a way to stop his roller skates?

    Mary complained to her father about how hard she thought life was. She didn't know how to make it and wanted to give up.

    Mary's father took her to the kitchen. He filled three pots with water and put each on a big fire. Soon the pots started to boil（沸腾）. In one he put carrots, in the second he put eggs, and in the last he put coffee powder. He watched them boil, without saying a word.

    Mary waited, wondering what he was doing. In about twenty minutes he turned off the fire. He took the carrots and eggs out and put them on different plates. Then he poured the coffee in a cup. He asked, "Mary, what do you see?"

    He asked Mary to touch the carrots. She found that they were soft.  He then asked her to take an egg and break it. She saw a hard-boiled egg after taking off the shell. Finally, he asked her to taste the coffee.  Its rich smell brought a smile to her face.

    Each of them had the same trouble, but each reacted differently. The carrot was strong and hard at first, but it became soft and weak. The egg was weak, too. But after going through the boiling water, its inside became hard. The coffee powder changed the water, and created something new. "Which one is you?" he asked Mary. "When trouble comes to you, are you a carrot, an egg, or the coffee powder?"

    Bill was a boy of 15. His parents didn't care about him. Bill often slept in class and always failed in his exams. Neither his teachers nor his classmates liked him.

    One day, Miss Jones, a new teacher, came to Bill's class. She began her lesson. She asked a question. "I'd like the smartest boy to answer my question. ''Then she said loudly, "Bill, please!”

    Bill was surprised. And he stood up without a word.

    "Just try it! I believe you can!" She encouraged(鼓励)Bill.

    After school, Miss Jones had a long talk with Bill. She told him that she cared about him and believed in him.

    Bill thought a lot that evening. From then on, he worked hard and Miss Jones helped him with his homework in the afternoon. She even cooked for him.

    Later, Bill had another exam. He was very excited to pass the exam. A change took place in Bill's heart.
