Stephen Hawking was one of the most famous scientists in this century. He was born in 1942. He's a world well-known on space and time. Stephen is researching some very big questions, such as: How did the universe begin? How will it end?

Stephen was a student at Oxford University. He studied math and science. Then, at the age of twenty, he became sick. He was so young, but the doctors said to his family, “He has only two more years to live.” As a matter of fact, the doctors were wrong—- he didn't die. He can't walk now but he uses a wheelchair(轮椅). He can't feed himself and get in or out of bed himself. But he refused to give in to the condition. He talks with the help of a computer. After Oxford, Stephen went to Cambridge University. Three years later, in 1965, he became a doctor of philosophy(哲学).

    Because of his serious health problems, it was difficult for him to draw diagrams(图表)or to write. So he started to think in pictures. With this new way of thinking, he became one of the most famous scientists in the world. In 1991, he met the Pope(教皇) in Rome. They talked about his ideas. Then in 1998, he wrote his first important book, A Brief History of Time. It sold more than 5.5 million copies in 33 different languages. He was once invited to China, he impressed us with his self-confidence, humorous and witty(风趣的) conversation.

    Each of us makes mistakes from time to time. In fact, we can get a lot from our mistakes.

    Donnie was a shy student and never answered questions in class. He was afraid to make mistakes. He never finished his homework because he didn't want to make any mistakes. Nothing changed till Marry Anne, a teacher, came to our class.

    One morning, Marry Anne asked Donnie to answer some questions. After a while Donnie was in tears because he made a mistake. Suddenly Marry Anne got a box full of erasers from the desk.

    "Look, Donnie," she said standing beside him. "I have something to show you." She took out the erasers, one at a time, and put them on the desk.

    "See these erasers, Donnie?" she asked. "Do you know why the erasers become smaller and smaller? That's because we make mistakes. But we erase the mistakes and try again. That's what you must learn."

    "Here," she said, "I'll leave one eraser on your desk, so you will remember that everyone may make mistakes." Donnie looked at Marry Anne and smiled.

    Donnie changed a lot from then on. He knew that everyone had the permission(许可) to make mistakes as long as you learned them and tried again.

    A 2-year-old boy is being described as a hero after using Face Time to save his mother after she was badly hurt.

    According to a report from KGUN, Laura was trying to stop a fight between two dogs when one of the dogs bit(咬) part of her middle finger almost completely off.

    Laura tried to call 911 herself, but she said her hands were too badly hurt to make the call. "I asked my daughters to call 911, and they're four, and they were quite afraid to even touch the phone, because it was covered in my blood(血) ," Laura told KGUN.

    The mother continued to lose a lot of blood and thought she would go into a deep sleep--until her 2-year- old son Bentley came up with a dishcloth from the kitchen. After cleaning some of the blood off his mother's iPhone, Bentley continued to use Face Time to call Laura's friend Connie.

    "All I could see was his little forehead. I said 'Hi Bentley' and it was quiet for a little bit. Then I heard Laura shouting," Connie told KGUN.

    Connie then called 911, and Bentley unlocked the door to let firefighters into the house.

    Laura told KGUN she is very thankful for her little hero and has since taught all of her children how to call 911.

    Jane was from a small village in Southern America. Her family was poor and noodles were often their only food. Her parents couldn't afford to pay the electricity bill (电费), so she had to study by candle light.

    What was worse, to live on, her parents moved to a faraway village with the other four children. As for Jane, she didn't want to give up learning and she dreamed to enter a famous university. She stuck to living alone in her village.

    After Jane's parents left, she lived a really difficult life. Having no place to live in, the homeless girl had to sleep on the back seat of the school bus. Luckily, Mrs. Brown, the caring school bus driver, learned about Jane's situation and invited her to live with her family. Soon, Jane found a job in her school. She worked from 6 a. m. to 7:40 a. m. before the first school bell rang. She swept floors and picked up rubbish again in the afternoon. With the money she got from the work, she paid for her education. And she stayed up late in the evenings studying for all kinds of exams day after day.

    Jane's hard work made a difference to her life. She finished high school with unexpected results. She was accepted by Harvard, one of the world's most famous universities with full scholarship (全额奖学金).

The 18-year-old girl created her own future with her never-give-up attitude and hard work.
