Audrey Hepburn won an Academy Award as Best Actress for her first major American movie, Roman Holiday, which was showed in 1953. But she is remembered as much for her help as for her acting.

    Born in Belgium in 1929, Audrey's father was British and her mother was Dutch. Audrey was sent to live at a British school for part of her childhood. During World war Ⅱ, she lived and studied in the Netherlands. Her mother thought it would be safe from German attacks. Audrey studied dance as a teenager and during college. But when she returned to London after the war she realized she wasn't going to be a ballet dancer. So she began taking acting parts in stage shows. Later she began to get small parts in movies.

    But it was Audrey Hepburn's move to America that made her truly famous. In 1951 she played the character "Gigi" in the Broadway play Gigi and won popular praise. Two years later, Roman Holiday made her a star at the age of 24.

    Audrey made more than 25 movies. Among her most popular roles was "Hoolly Golinghtly"in Breakfast at Tiffany's in 1961. Three years later she played "Eliza Doolittle" in My Fair Lady. She was married twice. In 1989, the UN Children's Fund named Audrey a goodwill ambassador. She travelled all over the world in support of UNICEF(联合国儿童基金会) projects. The UN agency said she was a tireless worker. She often gave 15 interviews a day to raise money and get support for UNICEF projects.

    Audrey Hepburn often said her love to UNICEF was the result of her experiences as a child during World War II. Shesaid she knew what it was like to be hungry and to be saved by international help. She was a goodwill ambassador until her death in 1993 from cancer.

About 1 in every 160 children has autism（自闭症）. Lots of people are working hard to help those children. And luckily, there are also robots helping them. 

Catherine, a Hong Kong professor, has developed an educational programme. It uses role-playing robots. The programme, Robot for Autism Behavioral Intervention（RABI), is for children with autism between the ages of 3 and 18. Its purpose is to help them be more social（社会的）. According to Catherine, more than 1, 200 children have taken part in the programme since it was started in2015.

As we know, it is tough for people with autism to communicate with others. Others can't understand what they want to say easily. So they feel worried or nervous about half of the time. The robots teach them social skills to make them less nervous. In a typical class, two small robots act out social conversations on a table. It helps the children see the difference between proper and unacceptable behavior. After that, the daughter has been in the programme for seven months. Her social and communicative skills have improved a lot. 

More than 20 non-profit（非盈利的）groups and public schools in Hong Kong and Macao have joined the programme and helped develop it. Catherine hopes the programme can help more children with autism. 

Every kid in my neighbourhood knew about the Christmas Witch (女巫). She was an old woman who left her Christmas decorations(装饰) up all year long: a twinkling tree in the living room, a plastic wreath on the front door, and…

I was told the decorations were meant to get kids closer to the house so the Christmas Witch could take them, and I promised myself I would never go near that place. But when I turned fourteen, I got a newspaper road map and found I'd have to deliver(投递) papers to the Christmas Witch. 

My first day of delivery was a dark, cold March morning. The sky was just turning pink as I got close to the last house on my road map— that of the Christmas Witch. I walked up the stairs quietly and placed the newspaper by the door. Then I quickly turned around. Just then I fell down the stairs. I hurt my ankle(踝关节), unable to walk. 

The light was on. The door opened. Someone came out. It was the Christmas Witch. 

"Dear me, " said she. "Are you all right?" Speechless, I pointed at my ankle. "Come in; make sure you're okay, " she smiled, not a wicked- witch smile, but a nice smile. I had no choice. Holding her hand, I got into her house and was placed in a chair. "Relax. " She hurried into the kitchen and returned a moment later, handing me a cup of hot tea. "I call your parents, " she said. 

I told her my mother's number. She got through, told my mother everything and turned, "Your mother will be here shortly. ""Thank you, Mrs Wright. ""You're welcome. " She sat down across from me, smiling. "You don't have to call me Mrs Wright; you can call me Christmas Witch. "

I was a bit embarrassed (尴尬的). "It's alright. I hear what people say, " she smiled. "You do have lots of decorations, "I said. "I think it's pretty, " she replied. "But people think it's… strange, "I said. "They don't understand why I leave up my decorations, " answered she. 

Like most teenagers, I just asked the next question, "Why?"

"It was because of my son, Anthony, " said Mrs Wright. "Anthony planned to come home before Christmas. He called me on New Year's Eve, telling me to leave up the Christmas decorations. But three days later, Anthony died because there was something wrong with the plane. My boy never made it back home. Even though I know it doesn't change anything, I won't take down those decorations, even after all these years. " Mrs Wright wasn't a witch. She was a sad, lonely mother fighting with a terrible sadness. 

The doorbell rang and my mother arrived. Held by my mother, I went home. My hurt ankle healed (康 复 ) quickly. Since then, whenever I delivered newspapers to Mrs Wright, she smiled, saying how much she enjoyed my visit. I didn't think of her as the Christmas Witch any more.
