    People often ask why "Uncle Sam" is a nickname (绰号) for the United States of America. The reason is strange but simple.

    Once there was a man called Samuel Wilson. He was born in Arlington, Massachusetts, on 3 September 1766. His nickname was "Uncle Sam". When Sam Wilson was 14 years old, he joined the army and fought in some battles (战役). At the end of the war (战争) he went to live in the state of New York. He opened a meat-packing business (生意) there.

Sam Wilson worked hard and loved his country. People in the city liked him. One day in 1812, a reporter from a newspaper visited his business. The reporter looked at some boxes of meat. He saw the letters "EA-US" on the sides of the boxes.

    "What do those letters mean?" he asked one of the workers.

    "The ‘EA' stands for (代表) ‘Edward Anderson'," the workman replied. "The boxes of meat are for him."

    "What about the letters ‘US'?" the reporter asked.

    These letters really stood for "United States", but the workman wanted to have a laugh. "Oh," he said. "They stand for Sam Wilson. He has this company(公司). We call him ‘Uncle Sam'."

    The worker did not think that the reporter would believe him. But the reporter wrote a story about his visit to Sam Wilson's business. He wrote that his workers called him "Uncle Sam" and that "Uncle Sam" meant the United States.

Many people liked using the name "Uncle Sam" as a nickname for the United States and soon they were all using it. In 1961, almost 150 years later, the United States government(政府) made the nickname "Uncle Sam" official (官方的).

    Bill is a boy in my class. He is really good at painting (用颜料画). We paint the same thing in the art class. Mine is OK, but his is great. Bill says, "I always paint at night. But ideas often come to me when I'm asleep (睡着). I dream (梦见) about paintings! I often see the finished paintings in my dreams, and the next day I know what I have to do." I can see why I'm not a good painter. When I'm asleep, I often dream about soccer.

    Alan is my good friend. We watch movies every Sunday. It's often at his home. We often watch old movies, Alan watches them and reads about them. I really enjoy talking to him about movies, because he knows a lot about them and he teaches me a lot. Alan doesn't play basketball or soccer and he doesn't play computer games, so some people think he's weird. But it's good to be different (不同的), and I think he's a very interesting boy.

    One evening last autumn, while Marcos Ugarte, 15, did his homework and his father, Eduardo, 47, prepared lesson plans, they heard screaming outside. It was from one of their neighbors, the Ma family. Then Marcos' eye was caught by a glow(火光) from there.

    "The house's on fire!" Marcos cried. Wearing only in shorts, the barefoot(光脚的) teen ran out with his dad. When they got there, Grandmother Yim Ma, mother Suzanne Ma, and son Nathan Ma were crying for help. Through the open front door, father Alex Ma was staggering(磕磕绊绊) down the stairs, coughing heavily.

    "Anyone else in it?" Eduardo asked.

    "My son!" Alex pointed to the second floor.

    Eduardo started up the stairs, but smoke and heat forced him to his knees. He crawled (爬) upstairs and down the hall where Alex said he would find Cody, 8, who had locked himself in a bedroom. Eduardo tried hard to open the door. But Cody made no reply, and Eduardo had to make his way back downstairs.  At the same time, Marcos saw Yim and Suzanne pulling a ladder, shouting: "Cody is at the window!"

    Marcos then placed the ladder near the window and climbed up. When Marcos reached the window, he pushed the screen into the room and managed to coax(哄) Cody out. Holding Cody with one arm, Marcos slowly climbed down the ladder. Cody was quickly sent to a nearby hospital, where he's treated for smoke inhalation(吸入).

    "You just don't see a teenager have that kind of braveness," said people around.
