A rich young man decided that he would like to do some diving(潜水) in the sea, so he bought a diving suit and all the other things that he needed, and took some lessons at a diving school. Then one day he walked into the water by himself and began to explore（探索） the bottom（底部）of the sea. He saw a lot of beautiful fish and other things, and then, after half an hour, he suddenly saw a man waving（摇动）his arms and legs around wildly near the bottom of the sea. He was wearing only a bathing suit. The rich young man was very surprised to see him, so he took out a plastic notebook and a special pencil, which could write under water, and wrote, “What are you doing here?” He showed the notebook to the other man, who then took the pencil and wrote, “Drowning!”（溺水）

     I don't really have a best friend but one of my good friends is Kristi. She is from America. I sometimes call her Kwiti. She is funny and kind. And she really cares about (关心) everyone and almost everything. She became one of my good friends at the age of five.

    Hello! I'm Bill Smith. I'm twelve. This is my sister, Jenny. She's ten. We are from the USA. But now we are in China. My father is an English teacher in a school. My mother is a doctor. They work hard.

    At school I have a friend. His name is Ben Jones. He's twelve, too. He's from England. We all like China.

    Mick Polly, an owner of a toy store, lives with his teenage daughter Carolina in Kentucky. He is known as the Bike Man. Over the past five years, Mick has built hundreds of bikes for needy kids.

    One day in 2012, a 13-year-old boy with a broken bike walked by Mick's house. "I was working in my garage(车库); and he asked if I could fix it," says Mick, now 53.

    The boy's bike had a broken wheel. Mick sent a post(帖子) on Facebook, asking his friends if they had the needed part. One friend saw the post and gave away two used bikes. Mick took parts from each to build a new set of wheels for the boy.

    Soon after, Mick repaired a bike for the boy's brother and fixed one for his sister. Word spread, and during the year, he had fixed up lots of bikes for local kids whose parents were not able to afford new ones.

    "People are throwing away bikes day and night," says Mick.

    Mick puts the bikes and bike parts in his garage. "I take off the good tires or the handlebars or the seats and use them," he says.

    Up to now, the bike man has repaired hundreds of bikes and given away nearly 700 newly repaired bikes. They're free, but the kids must agree on two things: They have to learn how to put waste things to good use and they have to try their best to study in school.

    If a kid's grades are low, Mick requires a teacher's note "saying that you're doing your best". Mick also hopes the bikes will get kids off the sofa. "When I was growing up, we all rode our bikes," he says. "Hopefully these kids can get some exercise."

①Aarrav Anil, a 13-year-old boy, has had a deep interest in mechanics (机械学) since childhood. He invented a smart spoon and stood for India to attend an international competition last year. In the competition, he won the first prize. But he didn't create his smart spoon to win a prize. He noticed his uncle who has Parkinson's disease (PD) (帕金森病) try to feed himself. Food kept falling out of his mouth, making him look like a mess. Aarrav wanted to make a change.

②More than 7 million people in India have PD. The disease influences the brain, causing patients to shake uncontrollably. As the disease progresses, it leads to difficulty in eating by oneself.

③Aarrav wanted his uncle to be able to eat by himself. This encouraged the boy to look for a way to help his uncle. So he took tools to his room with sensors (传感器) and a 3D printer. But not everything went well.

④"I was sad that I couldn't find certain parts I needed in India. I had to buy some from abroad." Aarrav said in an interview.

⑤Aarrav made a first model, but the spoon handle was not easy for his uncle to hold. "I've improved the invention. It needs to be waterproof (防水的). The spoon must be easily separated, so that it can be cleaned and replaced with a fork. And the spoon needs to be deeper to hold more food." the boy said.

⑥The smart spoon is now being tested at a local college. The test is expected to be completed in early 2025. Aarrav hopes that his smart spoon will be used in hospitals soon.
