Miss Kate taught physics in a New York school. Last month she was explaining to one of her classes about sound, and she decided to test them to see how well they had understood her explanation. She said to them, "Now, I have a brother in Los Angeles. If I was calling him on the phone, and at the same time you were 80 meters away, and were listening to me from across the street, which of you would hear what I said earlier, my brother or you and for what reason?"

A boy at once answered, " Your brother, Miss Kate, because electricity travels faster than sound waves(声波).

"That's very good." Miss Kate said, but then Jenny said, "I don't agree. Your brother would hear you earlier because it is 11 o'clock here, it's only eight o'clock in Los Angeles."

    One day a little boy came into a fruit shop. He had five dollars and wanted to buy some apples. He said to the shop owner,“Give me $5 worth of apples, please.”

    When the shop owner gave him the apples, the boy counted them and felt very surprised. Then he said:“Last Friday, my mother bought apples here for $5, too. Why did you give me fewer apples?” “Don't ask questions, boy. I have no time for questions.”

    “Excuse me, sir.” said the little boy, “but…”

    “It is all right, my boy,” said the shop owner, “Don't you know? The fewer apples you get, the less fruit you will have to carry.” “All right.” said the boy and he gave $4 to the shop owner. He was just going to leave the shop when he heard the words:“Come back! You must pay me $5.” But the boy replied: “Don't you know? The fewer dollars you get, the less money you will have to count.”

    Everyone strongly wants to be a success. What is important for success? Most people think that confidence, hard work and enemies are main factors(因素) leading to success. Ronaldo said he believed he was a better player than Messi in an interview published in Spanish sports paper on Sunday.

    Talking about his achievements of his career, Ronaldo showed pride. Ronaldo was also asked about Messi, who was seen as his biggest enemy to be considered the best player in the world. “Whether you are No. 1 or not is not so important. Although some people may think Messi to be the best,I think that I am.” Ronaldo said that boos(喝倒彩的嘘声) didn't make him sad, but encouraged him to practice harder.

    Ronaldo insisted that hard work was important to be a top player, though at times he felt a great pain for his training, saying a body “was not used” to training hard and playing twice a week. But no pain, no gain. He said he had changed his life to make sure he was in top condition, saying that when in the past he usually went out to relax, but now he “goes home to rest for tomorrow.”

    “Football is my life. It's what I love most.” he explained.
