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.

    Tom is a junior high student. He is good at some subjects but his favourite subject is chemistry. Yesterday he met some trouble when he had his chemistry class.

    At that moment, Tom was doing an experiment in class. He tried twenty times, but he couldn't succeed. So he decided to stop doing the experiment. He felt really unhappy.

    His teacher came up to him and asked why he was unhappy. Tom said, "All my work is in vain (白费力气). I fail twenty times and I get nothing."

    Tom's teacher touched Tom's head with a smile. He said to Tom, "Oh, you do a lot and you can get a lot from the mistakes. At least, you know that there are twenty ways you can't use to do this experiment."

    After hearing the teacher's words, Tom became excited. He kept doing the experiment, improved his methods, and he succeeded at last.

    Sarah is thirteen years old. She comes from Manchester in the UK; but now she is living in Geneva in Switzerland. Her father works for the UN and because of that she and her parents have to move a lot.

    Sarah has lived in five different countries: the US, Morocco, Turkey, Switzerland and the UK. But she doesn't remember the UK very well, because they moved to the US when she was only two years old. Still, she visits it often during vacation. She usually stays at her grandparents' house in Manchester. She likes visiting her grandparents, because they often take her to the Peak District National Park. It is very beautiful. Sometimes she stays with her uncle in the little town of Penzance in Cornwall. Sarah likes Penzance, too, but it's often very cold and windy. Penzance is very different from Geneva. In Geneva it is much warmer (更暖和的) in summer, but. also colder  in winter.

    Sarah likes going to new places. But every time she moves, she has to leave behind her old friends. She always needs to make new friends, and then leave them again. Luckily, they can write e-mails to tell each other about their lives.

    Life is full of surprises and you never know how things will turn out.

    Sir John Gurdon is a good example of this. As a boy, he was told he was hopeless at science and finished bottom of his class. However , the very same Gurdon shared the 2012 Nobel Prize in Medicine with Japanese stem cell (干细胞) researcher Shinya Yamanaka.

    Like so many scientists, Gurdon shows us where the power of curiosity and perseverance (坚持不懈) can lead.

    At the age of 15 in 1948, Gurdon ranked last out of the 250 boys at his high school in biology and every other science subject. Gurdon's high school science teacher even said that his dream of becoming a scientist was " quite ridiculous".

    In spite of his teacher's criticisms, Gurdon followed his curiosity and kept working hard. He went to the lab early and left later than anyone else. He experienced thousands of failures.

    "My own belief is that we will, in the end, understand everything about how cells actually work," Gurdon said.

    In 1962 ,Gurdon took a cell from an adult frog and moved its genetic( 基因的 ) information into an egg cell . The egg cell then grew into a clone(克隆) of the adult frog. This technique later helped to create Dolly the sheep in 1996,the first cloned mammal(哺乳动物) in the world.

    In 2006, Gurdon's work was developed by Yamanaka to show that a sample (样本) of a person's skin can be used to create stem cells. Using the technique, doctors can repair a patient's heart after a heart attack.

    "Luck favors the prepared mind," Gurdon told the Nobel Prize Organization. "Ninety percent of the time things don't work ,but when they do ,you have to seize(抓住) the chance. "
