"Hey, how are you doing? I'm Courtney. What grade are you in? What's your favourite book? Elephant and Piggy? Yeah, I got it."

If you think you have walked into a library with a 1 like that, you are exactly wrong. 2, you've entered the workplace of Courtney Holmes, known as the Storybook Barber (理发师).

Two years ago, his small town held its first yearly Back to School Party, offering needy families a 3 to learn about free resources in the community. Holmes, a warm-hearted barber agreed to take part. Though he was very busy, he choose to donate his 4 to give free haircuts to needy kids so that they'd look tidy on that first chose to donate his day of school. Suddenly, a(n) 5 went through his mind, "The kids should go on getting their free 6 by having to read a book to me."

The idea was so 7 that he continued it for the next two years. Kids aged 5-10 would grab a favourite book, sit in the barber chair, and 8 while Holmes snipped (剪). If they stuttered (结结巴巴) over a word, Holmes was there to 9.

After the haircut, they'd 10 the books, from the characters and vocabulary to the themes — just like in school, only more fun. Holmes realized that not every 11 had the time to read with their kids. He had a talk with his neighbour Mr. Smith, "You have four kids, and you are so 12 that sitting down and listening to them read is the last thing you have time to do. Just bring in your kids and let them read to 13."

Holmes added, "I, too, 14 the free snip-and-reads. Last month, there was a seven-year-old boy, Bob, who tried hard to read through his book, stuttering over words, and then I asked the boy to take the book home and practice. 15 the kid came back a few days later, he read it with no problems. That inspires (鼓舞) me," said Holmes.

Food waste is a world problem. In June 2020, the United Nations warned that the world is nearly in the worst food crisis(危机)in 50 years.

In China, many actions have been taken to1people to save food, such as the" Clear Your Plate" campaign (光盘行动). The campaign means we should finish our meals2. Now Liu Jichen, a 24-year-old student, is making a big difference with technology. He3a WeChat program called Clear Plate to help people fight food waste. After meals, users can open the program, share photos of4plates online. Then they can collect points and use them to buy gifts or give away meals to people5. He has succeeded in making people have the habit of clearing their plates through a more6way.

ln 2018, the program was put into use on October 16, World Food Day. The idea to develop such a program came from Liu's7. In 2017, he found that a restaurant would give customers who finished off their food a card and offer small gifts8they cleared their plates six times."It's a great idea, but cards are easy to9,so l thought of using Internet tools like AI," he said.

New laws are being considered to give clear10on avoiding food waste, and refusing food waste should be a lifestyle(生活方式)choice for everyone.
