One day while driving from my home to work. I noticed a car in front of me had a wobbly(不稳定的)wheel. It was clear that the wheel had been changed recently and had not been fixed correctly. On a slow road this would not show much of a problem but I knew a highway was coming soon. There the traffic would move much faster and the driver would be in danger as the wheel could come off at that speed.

    I was driving a large jeep at the time and the car in front was a small one driven by a young lady on her own. So as I tried to flash(闪)my lights and wave her to pull over,  I was worried that she wouldn't' pull over on the road side when she found in her mirror a single man chasing(追) her down in a jeep and waving for her to pull over.

    Thankfully. she trusted more in the good nature of people and pulled over where I could explain the problem. She said the wheel was changed only the night before and that she would pull into the nearest garage(修车间)where the repairman had tools to fix the wheel correctly.

    My belief is that the act of kindness was hers and not mine. How so? Well, it was she who chose to believe in the possibility that people are good over the belief that bad things would come from being waved over to the side of the road by strangers.

    I am glad I was able to wave her down in time and so a serious accident might have been avoided. But I am even happier that she believed in a stranger.

    Mrs. Hunt comes back from work. She tells Mr. Hunt about a nice dress. “I see it in the shop every day,” she says “and…”

    “And you want to buy it?” says Mr. Hunt. “How much is it?”

    “Two hundred and sixty dollars.”

    “Wow, two hundred and sixty dollars for a dress? That's too much!”

    But every evening when he comes back, Mrs. Hunt only speaks about the dress, so at last he says, “Oh, buy the dress! Here is the money!” She is very happy.

    But the next evening, when Mr. Hunt wants to have a look at the nice dress, Mrs. Hunt says “I don't want to buy it.”

    “Why not?” he asks.

    “Well, it's still in the window of the shop after a week. So I think no one wants this dress. And I don't want it, either.”

    A call came into Jimmy Gilleece's bar this past March. A newly married woman who had spent the afternoon at the dive beach bar in Wrightsville Beach, North Carolina, couldn't find her wallet. She didn't care about her ID, credit cards, or $150 — but her wedding ring was inside it.

    Gilleece, 42, the boss of the bar, didn't like the idea that there was a thief at his place. So he set out to find the wallet. He spent hours looking for the footage (录像) from 16 different cameras, watching the woman's every step in the bar. Finally, a young man caught his eyes. He picked up something from the place where the woman stood and put it in his pocket.

    Gilleece posted the picture on the bar's Facebook and asked if anybody knew who the guy was. Within hours, 17-year-old Rivers Prather came and said he had taken the wallet and told Gilleece he'd done it because he hadn't eaten for two days. He said he saw the ring but thought it was not real, so he took the money and threw the wallet into the ocean. Then he bought a sandwich.

    Prather wasn't getting along with his family and lived in the woods for weeks. Gilleece saw him for what he was: more of a kid than a thief. He found two local divers to search the waters where Prather threw the wallet. After waiting for hours worriedly but luckily, a diver came out from the water with the wallet in his hand, and inside was the ring.

    "Most people would give the footage to police, but the boss chose to help me," Prather told CBS News. "I say thank you to him every day."

    On most weekends, you can find Zoe Stone. 8. in front of a computer. But she isn't playing games or watching videos. She's learning how to write code.

    Code is a set of instructions (指令). It tells a computer what to do. Coders are the people who write the instructions for a computer. Coders make websites or apps. Apps can be used for everything from playing games to checking the weather. Coders solve problems and work together. They know how to think big and small.

    Zoe began to learn coding when she was 4 years old. She uses coding to create art, solve problems and make games. Zoe likes coding because it's creative. "Coding is really fun," she said. "You can show what you think in what you make."

    How does Zoe learn coding? She takes classes at Code. org. The website offers hundreds of free code lessons for kids. In fact, more than 29 million students in 180 countries use it. It hopes to bring coding to even more kids.

    "We believe that every child should have the chance to learn about computers and coding," said Alice Steinglass, the president (负责人) of Code. org. "Computers are part of our world," she said. "It's important for kids to understand how they work."
