    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).

A new match-tiles-style game(消除类游戏) called "Yang Le Ge Yang" or "Sheep A Sheep"was popular on WeChat's mini program for several months last year. Developed by Beijing Jianyou Technology, the game had 2. 6 billion views on Weibo under its hashtag(话题标签) and related short videos were viewed widely. 

The game features sheep characters and challenging levels, with only 0. 1% of players able to pass all levels according to the developers. Many users struggle with the second level, which is particularly difficult. The game also provides customization(定制化) choices for players who successfully complete matches by allowing them to change their sheep skins, along with interesting background music. 

By dividing game players into different groups according to their provinces, "Yang Le Ge Yang" creates a strong sense of belonging and encourages players to win and bring honor to their provinces. What's more, game tools are available to those who share the game on social media, which has helped to make it more popular. The game's "Hard Fun" style has made it a hit among players looking for a challenge, and advertising opportunities provide potential income (潜在的收入) for the company behind the game. Users must watch in-app ads to get more powerful tools to overcome difficulties in the matching process. 

However, will "Yang Le Ge Yang" be popular for much longer or will it be replaced and forgotten? Similar, more trendy games are likely to follow soon, as often happens with such small and easy-to-make games. 

One afternoon, my son Eric asked me, "Are all people the same even if (即使) they have skins (皮肤) of different colors?" It was a difficult question. I 1 for a minute and said, "Let's go to a 2 shop. I'll show you something."

At the shop, we bought some apples in different colors--red, green and yellow. After we 3 , I told Eric, "It's time to 4 your question." I put one apple of each color on the table. Eric watched them with a surprised(惊讶的) look on his 5 . "Eric, can you tell me which apple you like best?" Eric picked up the red apple 6 . Then I peeled (剥皮) all the apples and put them back on the table. "OK, Eric, now tell me which one you like best." He said, "I can't tell. They all look 7 now." I said, "Eat them and see which one is which." He ate and said, "I got it, Dad. People are like 8 . They are in different sizes and 9 . On the outside of the apples, some of them may not look as 10 as the others, but are the same inside."

Eric knew everything. I didn't need to say or do anything.
