Roger, a young man from China, has taught Chinese in a primary school in England for 3 years．A lot of children like his class and he enjoys teaching them very much．All the pupils are quite interested in what Roger teaches them．They learn quickly and do everything carefully．

    One day he said to the children, “People in a lot of Asian countries wear white clothes at funerals(葬礼), but people in America and in Europe wear white in the weddings because white means purity and happiness．What colour does an English woman wear when she gets married?”

    Mary said, “White, sir, because she is happy．” “That is good, Mary,” Roger said．“You are quite right．She wears white because she is happy．”

    But then one boy in the class put up his hand．“Yes, Dick?” Roger said, “Do you have a question?” “Yes,” Dick said．“Why do men wear black in our country when they get married, sir?”

    Pat McGee noticed her daughter hadn't returned to the dentist's waiting room just before her surgery (外科手术). She walked to the bathroom and found Jessica McDaniels, 32, in there, crying.

    McGee took her daughter into her arms, "We're going to say 'goodbye' to the old Jessica," she said. "And 'hi' to the new Jessica."

    McDaniels, from St. Louis, US, had been wishing for this day since high school, when the bullying (霸凌) about her teeth started. Now that it was finally happening, she was worried and afraid.

    It was a social media post two months ago that got her there. Someone posted a photo of McDaniels with a comment about her overbite (龅牙). The post was shared many times, with many people making unkind comments on her appearance.

    The bullies didn't know the road McDaniels had traveled. She had nine operations on her ears from age 2 to 12 years old. She was almost deaf in her right ear. Her adult teeth didn't start coming in until she was 11 or 12, and doctors couldn't figure out why they were pushed outward. It got worse as she got older. McDaniels had been trying for years to get her teeth fixed, but it was always too costly.

    When her story got out, dentists wanted to help her. One of them, Maryann Udy, got in contact with McDaniels and offered her a new smile - free of charge. McDaniels wasn't sure at first, so she called her mother. The mother told her that Udy was her angel. "You need to do it," she told her daughter.

    The surgery was long and complicated (复杂的). It took weeks for the swelling (肿块) to go down, and several more months before McDaniels' new smile was ready. Later that year, she looked at her old photos online and smiled. "I loved her," she said. "She's thankful to be in less pain, to be on the way to a new smile. Sometimes, though, it feels like something is missing from who she was." Still, she loves taking selfies and admiring her new appearance. "I looked good before," she said. "I look even better now."

    It was a Christmas night. I was an unlucky nurse who had to work on such a beautiful festival. When I was complaining(抱怨)about it, three people appeared at my desk — a tired woman and two children.

     "Are you all sick?" I asked doubtfully because they seemed all right.

    "Yes," the woman answered weakly and lowered her head.

    But when they started to present their problems, things became unclear. One child had a fever, but his temperature was OK. The other child had an earache, but she could not tell me which ear hurt. It seemed that the mother was pretending(假装)to cough.

    Something was wrong. But I only explained that it might take a while before a doctor could meet them. "Take your time, please," said the mother. I checked their charts — no address. Suddenly I knew, they were homeless while the hospital was warm.

    The family huddled(蜷缩)together under the Christmas tree, smiling and talking with each other sweetly. Quietly, I went back to the nurses' station and told them what happened in the waiting room. It was just like God sending us a gift on Christmas Day. The nurses' station suddenly came back to life. All the nurses went into action for "a Christmas emergency(急诊)".

    We took out our meals for our Christmas "patients". We also put together oranges and apples as presents. We tried to exceed the needs of a family who only wanted a warm place on Christmas night. Later, the little girl kissed me and said, "Thanks for being our angel(天使)."

I took my 9-year-old daughter Susan and 5-year-old son Robbie, to the shopping centre. As we got there, we saw a big sign that said, "Petting Zoo". The kids jumped up and asked, "Daddy, can we go?"

Both my wife and I were out of work. However, I said, "Sure", giving them a quarter each. They went away, leaving only fifty cents left in my pocket.

A petting zoo is made up of a hundred of little baby animals of all kinds. Kids pay their money and stay in the enclosure (围场) pleased with the little animals while their parents shop.

A few minutes later, I saw Susan walking along behind me. I was surprised and asked what was wrong.

She said sadly, "Well, Daddy, a ticket for petting zoo costs fifty cents. So I gave Robbie my quarter." Then she said the most beautiful thing I ever heard. She repeated the family motto (座右铭), which is "Love is Action!"

I knew clearly no one loves little animals than Susan. She had watched both my wife and me do and say "Love is Action!" for years, and now she had put it into her lifestyle. It had become part of her, because she knew the whole family motto. It's not only "Love is Action"; it's "Love is SACRIFICIAL (牺牲的) Action!" Love always pays a price.

I was moved. We went back to the petting zoo. Susan stood with her hands and chin (下巴) resting on the fence and just watched Robbie go crazy petting and feeding the animals. I had fifty cents burning a hole in my pocket. I put my hand into my pocket and took out the money. Sure, I must do that!

 Wu Jingxun, 46, is from Foshan, Guangdong Province. About 15 years ago, when he came to volunteer at a village primary school in Sichuan Province for the first time, he found the kids there didn't have enough books to read. He also found that there weren't any books at the students' homes.

 After that, Wu and his friends at Friends Camp, a volunteer organization (组织), bought many books for the primary school.

 One year later, in 2007, when they visited the school again, they found that children in the village did not know how to read. Even though you put great books in front of them, they just looked through the picture books. They didn't learn from the books. This made Wu and his friends think how to teach children to read.

 In some good primary schools, grade-three students can finish reading 15 books a year and, sometimes even more. But, in poor villages, grade-six students only know about 1,800 Chinese characters(汉字).

Now Wu focuses on(专注) picture books and science as he volunteers to teach children how to read. "If they can take up reading as a good habit, they can benefit (受益) more. They can read in their free time but not just play games or use Douyin on their phones," Wu said.
