    Kyle walked up and down as he waited for his turn at the back stage. This would be his most important piano performance yet. At ten years old, he was the youngest performer in the Christmas concert. Although his teacher Ms. Neal said he was good enough at the song he would play, he still practiced it more than 30 times that week. When he closed his eyes at night, the music played over and over again in his mind

    Now, the day finally arrived, but Kyle was not sure he was ready. He kicked a small ball which was picked up from a Christmas tree, and then looked himself in a mirror—trying to make his bow tie more smooth and beautiful. He thought of his mom who bought him the new suit with this bow tie. He would make her feel proud of him. He noticed that his hands were shaking. How could he play the notes of the song if his hands were shaking? He took a deep breath and tried to calm down, but his hands shook more.

At this time, Ms. Neal walked up to speak to him. “I have something for you,” she said, putting a smooth black stone into Kyle's hand. “It's a special stone. There's no other one like it in the world. You've practiced so much, so you don't need anything else.”

    The stage lights reflected on it. “Thank you.” Kyle said.

When Kyle's name was called, he rubbed the stone, stepped onto the stage, and played better than ever. After his performance, he noticed that Ms. Neal had a whole bag of black stones. “Why did you say this one was so special?” he asked.

His teacher smiled, “Like your talent, it is special because it belongs only to you.''

    Tom has a strong and faithful(忠诚的) dog, Bruce. The dog likes playing with Tom. Sometimes he also follows Tom's father to work.

    One morning when Tom's father worked in the field, he took off his coat and put it on the ground under a big tree. He turned to the dog and said, "Watch my coat, Bruce!"

    Bruce sat down on the coat. Later Tom's father remembered he had to buy some food. So he hurried to the shop. After shopping, he went home directly and forgot all about his coat and the dog.

    Late in the evening Tom looked for his dog everywhere in the house, but he couldn't find him. At this time Tom's father suddenly remembered his coat and the dog. He went back to the tree at once. He found that Bruce was still sitting on the coat!

    People usually hate mice, but one mouse has won the hearts of the people all over the world—the famous Mickey Mouse.

    Fifty years ago most movies were silent. A man called Walt Disney made a cartoon mouse that could talk his movies. He named his mouse Mickey Mouse. People, both young and old, were very excited at the talking mouse. Children loved to see their friend, because he brought joy and laughter to them.

    Mickey was a clean mouse right from the beginning. Perhaps this is one reason why people hate real mice and love Mickey Mouse. In his early life Mickey made some mistakes. People were angry. They wrote to Disney and said that they did not want Mickey to do silly things. So Disney made a new animal named Donald Duck. He also made a dog called Pluto. This dog does stupid things and makes mistakes wherever he goes. Now our Mickey Mouse is not only clean but also important. He appears as a beautiful and clever star. He has his friends in almost every country.

    A little boy was playing in his sandbox on a Saturday morning．While he was building roads and houses in the soft sand, he discovered a large stone in the middle of the sandbox．

    The little boy pushed and pulled, but every time he thought he had made some progress, the stone tipped (倾斜) and then fell back into the sandbox．The little boy tried his best, but his only reward was to have the stone roll back．

    Finally the boy cried．All that time the boy's father watched him from his living room window．At the moment tears fell, his father came to the boy and the sandbox．Gently but surely he said, "Son, why didn't you use all the strength that you had?" The boy said sadly, "But I did, Daddy, I did! I used all the strength that I had! No, son," corrected the father．"You didn't ask me．"With that, the father reached down, picked up the stone and removed it from the sandbox．

    Do you have "stones" in your life that need to be removed? Are you discovering that you are too weak to lift them? There is ONE who is always ready to give us the strength we need．Isn't it funny how we try so hard to do things on our own?

    I was in line waiting to pay. A little boy in the front was buying some clothes.

    I noticed that the little boy was paying mostly with change (零钱). It seemed that he had broken his pig bank to do this shopping. However, the cashier(收银员) told him he was $ 8.00 short after counting his money.

    It was clear that the boy had already used all the money. The lady in front of me said, "Well, I could pay half of that." I told the boy that I could pay the other half. We dug into our handbags. However, both of us only had ten-dollar bills (纸币). Other shoppers began digging into their pockets to find some change. It was amazing and touching as all these strangers seemed to react (反应) with the same mind. All wanted to be of help. Within minutes the cashier said, "I have too much money." The cashier didn't need our ten-dollar bills. Then the lady in front of me said, "Wait! I didn't even get a chance (机会) to give anything!"

    I smiled at her and said, "You did your share, because it was your idea and you started all this." The little boy smiled and thanked us. I left with a good feeling. I saw the love and goodness of others all around me. The woman in front of me smiled and said, "It feels good to give, doesn't it?" I smiled back and said, "Yes!"
