When my brother and I were children, we spent a few weeks each summer in the countryside with our uncle. He was a geologist and loved to go on long walks to find stones to add to his collection at the university. More often than not, we followed him.

      One day, we left early, and this time, our uncle gave us two backpacks. “ You can help me carry the samples(样本),” he explained.

      Surely, why not? The whole day, we walked around the countryside, and every now and then, our uncle put stones in our bags. We were a bit surprised that sometimes he also took some stones out from our bags, but thought he had just found better samples.

      We reached the house in the late afternoon. The backpacks were so heavy that we were really tired out when we put them on the ground. Yet our uncle's backpack was half-empty.

      “Why did you give us so many stones?” we asked.

      “I didn't. You did,” he said, waiting for a while before continuing. “ You did not know it, but I made you go through a little attitude(态度) test today.”

What do you mean an‘attitude test'?” we wanted to know.

      “It is something someone once did to me. You see, I listened to every word you said. And whenever you complained(抱怨) about anyone or anything, I added a stone to your bags. And whenever you talked about something in an attitude of positive thinking, I took out a stone. And now look at your backpacks.”

      We did. They were full.

      “I hope you remember this little attitude test. You see, your negative thoughts are like stones. You carry them in your mind just like those stones and start paying attention to what you say and how you say things.”

      This little lesson was one of the most important lessons I ever had. And I remember my uncle with great love for teaching us one of the most important lessons in life – the power of attitude.

    One day Mrs. Smith invited many people to her house. She wanted to cook them a good dinner of meat and soup. She had five daughters. They were all busy. Mrs. Smith was busy, too. She forgot to put any salt into the soup. So she asked Mary, one of her daughters, to help her. “I can't, Mum. I'm busy now.” said Mary. She asked the other girls, but got the same answer. So she did it herself.

    Now, Mary thought she should help her mother. So she put some salt into the soup. And then all the other girls did the same.

    Mrs. Smith put the soup on the table. The friends took a little soup and their eyes opened wide. She took the soup, then she knew. “Which of you girls put salt into the soup?” she asked. “I did, Mum.” All the five girls said together.

    Once upon a time, there was a tree which wanted to become a treasure box. One day, a farmer cut it down and sold it to a carpenter(木匠). The tree was happy because he thought the carpenter would make it into a treasure box.

    To its surprise, the carpenter made it into a feed box for animals. The tree felt very disappointed because that was not its dream. Several years later, the feed box was thrown away. Someone picked it up and placed it into an old temple. The tree forgot its dream little by little.

    One day, a couple came to the temple. The woman gave birth to a baby boy. There wasn't a bed in the temple. So they placed the baby in the feed box. They loved him and regarded him as their treasure. The tree suddenly realized that it became a real "treasure box" at that time.

    Sometimes you may think your dream will not come true. Don't forget your dream. It may be realized in another new way.
