Some people remember the things by writing notes to themselves. Then they leave the notes in obvious(明显的) places, such as on the table or on the floor in the middle of the living room. I don't think I like to write notes to myself. Most of the time I lose them or forget to look at them until it's too late. I prefer to use an alarm clock to tell me what I should do. I have ten alarm clocks in my house. They could tell me about things. For example, if I have to make a telephone call at a certain time, I'll set an alarm clock to go off a few minutes early and put the clock by the telephone. Or if I want to watch a certain television program, I'll set an alarm clock at the right time and put the clock on top of the TV set. I can remember almost anything if I use my clocks. However, sometimes an alarm clock goes off and I don't know what it means. I always remember setting it, but I do not know why I set it. If the clock is by the telephone, I know I may have set it to tell me to call someone, but I can't be sure. I might have set it to tell myself that somebody was to call me at a certain time.

    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 was at bottom of his class. Now, aged 79，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) can lead.

    When he was 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(批评), 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 of the adult frog. This technique later helped to create the sheep Dolly 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 this 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.

    The Kings lived in a small house in New York with their child. Sometimes Mr. King came back from work very late. When his wife and the child were asleep, he opened the front door of his house with his key and came in very quietly.

    But one night when he was coming home late, he lost his key. So when he reached his home, he rang the bell. Nothing happened. He rang it again. Again nothing happened. Nobody moved inside the house. Mr. King knocked at the bedroom window. He spoke to his wife, he shouted, but she didn't wake up. At last he stopped and thought for a minute. Then he began to speak like a small child. "Mother," he said, "I want to go to the toilet." He spoke quietly, but at once, Mrs. King woke up. Then he spoke to her, and she opened the door for him.

    Kathy could still remember the night she had to leave her home in Hungary. It was the beginning of World War II and her family had to leave their country as soon as possible. She quickly filled a bag with a few pieces of clothing, her diary, and her treasure—a beautiful silk scarf.

    Kathy and her best friend, Monica, had asked their parents to buy them matching scarves. They each would wear the scarves as a symbol of their friendship. Kathy had no idea that she was going to America that night and would not be returning.

    Kathy kept that special silk scarf for many years. One day she decided to give it to her granddaughter, Eliza, to wear to her first job interview for good luck. Kathy was afraid that Eliza would lose the scarf, but the granddaughter promised, "Don't worry, Grandma, nothing's going to happen to your scarf. You'll see. It is going to bring both of us luck today." And with that, Eliza kissed her grandmother and left for the interview.

    That afternoon Eliza left the interview, feeling sure that she had got the job. So she decided to celebrate by going to a restaurant. As she was sitting at her table, she felt someone looking at her. Sitting next to her was an old woman, who could not take her eyes away from her.

    "I'm sorry, do I know you?" Eliza asked.

    "I'm sorry, dear, but you make me think of someone I once knew," the old woman replied. "My best friend looked like you and used to wear a scarf just like the one you're wearing around your neck." Eliza listened carefully, with her eyes and mouth wide open. She had heard stories of her grandmother's best friend and knew the meaning of the scarf. Could this be Monica, her grandmother's childhood friend?

    Eliza introduced herself and waited to hear the name of the other woman.

    "My name's Monica, dear. I lived in Hungary as a child, but my family had to leave when I was fourteen years old. I've been living here in California ever since." said the old woman.

    Eliza could not believe her ears …
