    It was July 17th of 2017. The little helpless girl, who had trouble walking, was going out into the wide world. In June 2016, I got the idea that I was going to America as an exchange student. With tears in my eyes, I said goodbye to my family.

    After I finally arrived at the airport in Burlington, Vermont. I was welcomed by my host family. They didn't know much about my disability. “I hobble a little, but I don't see it as a problem.” I think it's the will that decides what you can and cannot do, and the disability doesn't matter!

    Before I went to the US, I knew I was going to miss home. But I went! Why? I've been a fighter ever since I decided not to give up my breath when I was born! My mother wrote my host mom an e-mail and told her about my hard birth so they would understand. I remember clearly after she finished reading it, she came into the room, gave me a big hug and said, “You are a fighter.” My host family supported me so much during the year. In school, small notes were sent out to all my teachers, by e-mail, to tell them about my disability. Everything worked greatly.

    By the end of my year, exchange students were asked to talk about our years. I spoke in front of about 100 people! I was extremely proud of my “speech”. The following day some teachers stopped me and said, “Your speech was the best one.”

    My year in Vermont was the best thing I've done so far! I proved I AM A FIGHTER and that NOTHING IS IMPOSSIBLE!

    One day, I saw a boy shop alone at the shop I worked. He chose some school things he wanted and went to the checkout (付款台).

    The young shop assistant (店员) told him he needed to pay $37.60. The boy became very sad and said he only had $20. He took out one thing at a time, and at last he got down to his $20. With eyes full of tears, he asked if he could call his mom to pick him up. When he got through, it seemed that his morn was too busy to pick him up in a minute.

    He tried to stop the tears and walked outside to wait on the chair in front of the shop. This was too much for the young assistant. She kept looking outside to see if the boy was all right. Then she said, "I wish I could pay for the rest (剩余部分) of his  things." One of the other girls said she had a few  dollars. Then two others said they could help, too.

    These four young girls pooled their money and found they had more than enough to pay for the boy s things. Then they chose more school things, and gave them all to the boy. The boy laughed happily. His morn arrived much later, but he didn't just run to the car; he ran back into the shop and called out, "Thank you!"

    I was so proud (骄傲的) of my team that day. They did something wonderful for that boy and also found the pleasure (快乐) of giving.

    Mr Black was a businessman （商人） and he was very rich （有钱的）.One day he went on a trip to the countryside with his 5-year-old son Henry. He wanted to show his son how poor people lived, so they spent a day and a night on the farm of a very poor family.

    When they got back from their trip, Mr Black asked Henry, “My dear son, how was your trip?”“Very good, dad!”“Did you see how poor people lived?”the father asked. “Yes!” “And what did you learn?”Henry answered, “We have a dog at home, and they have four. We have a pool that is in the middle of the garden and they have a river that has no end. We have expensive lamps (灯) in the garden and they have stars.”

    When little Henry finished, Mr Black was speechless(无话可说的).

    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."

    A long time ago, there was a king who liked music so much that he ordered his men to get him the best instrument in the world.

    One day, a young man offered the king a harp (竖琴). The king took it to the palace, but when he started playing it, the harp was out of tune.

    Many other musicians tried it, and they agreed that the harp was useless(没用的) and the king had been cheated. The harp was thrown out as rubbish.

    A poor little girl later found the harp. And even though she did not know how to play, she decided to have a try. She played and played, for months and years, always with the harp out of tune, but she played better and better.

    Then one day, suddenly, the harp began to play the most beautiful music. It was a magic harp, and could only be played well by someone willing to spend much time practicing.

    One day, the king heard the music from his window, and the girl was invited to the palace. When the king saw the girl playing the harp, he was full of joy. At that moment he made the girl his private musician, giving her and her family lots of money.
