      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）."

    Jack Brown, an office worker, lives in Washington. He inherited(继承) a million dollars when he was 23. But he wasn't happy at all. When his college friends were looking for their jobs, he didn't have to. Jack decided to live a simple life like everyone else. He gave $10,000 of his money to a charity to help poor children live a better life. Today he is 36. He still wears cheap shoes and clothes and drives a small car only, but he is very happy.

    Up to now Jack has helped some children from poor countries all over the world by sending them $ 200 a month. The money was used for the children's study, food, medicine and clothing. Jack received a report each year on the children's progress. They can write to each other, but usually the children do not speak English.     

    When Jack first heard about these children, he wanted to help them. "It was nothing special," he said."Until I went to these countries and met the children I was helping, I didn't know anything about their life. "Once lack went to meet a little girl in Africa. He said that the meeting was very exciting. "When I met her, I felt very, very happy," he said. "And I saw that the money was used for a good cause. It brought me happiness. I want to do everything I can to go on helping these children. "

    This is Cara and Ben. They are twins(双胞胎). They are twelve. This is their bedroom. It's a nice room. There are two beds in the room. The yellow bed is Cara's and that green one is Ben's. The twins have one desk and two chairs. The chairs look the same. Cara's sweater is on his bed. Ben's coat is on his chair. Their clock, books and pencil-cases are on the desk. Their school bags are behind the chairs.

Qu Juanru is the official inheritor(官方继承人) of Jiaxing City Tongxiang flower­drum opera. She began to be on the stage when she was a teenager. "My mother died when I was 14. I've lived with my father since then. In the old days, women were not allowed to perform opera. However, my father always supported me when I tried to sing," Qu said.

Qu started performing in the local troupe(剧团) called Aimin Flower­Drum Opera. Later, the troupe was disbanded(解散), and she went back to farming.

After that, the young girl tried to set up the troupe several times but failed. She really lived a hard life at that time. But she didn't give up.

In 2001, some developers planned to rebuild Wuzhen. They thought a place which has no culture is of little significance(意义). So they wanted to bring back local customs, including the Tongxiang flower­drum opera. Qu was their only hope.

Knowing she could sing again, Qu was so excited. Whether it's cold or hot, Qu always gives her everything on stage in Wuzhen. She has six rounds(场) of performing every day and each round lasts 30 minutes. In 2017, she was badly ill, yet it didn't stop her.

"I can still sing and perform. I'd love to be here," Qu said. In her opinion, opera life is a wonderful dream that can't be missed.
