Several days ago, Brenda had a car accident that led to one of her legs being cut off. Since then she didn't talk to anyone.

     “I wish I could bring her friends to visit her,” said Brenda's mother. “But it's a long bus trip.” The nurse smiled, “Don't worry. We have a plan.”

    Later that day, the nurse had taken Brenda to another room. “Here's your new roommate, Annie Wiggle-Do,” the nurse introduced a dark-hair teenager on the other bed.

    As soon as the nurse left, she jumped out of her bed with her only foot and sat at the other end of Brenda's bed, “I lost my leg from bone cancer,” she said. “What happened to yours?” Brenda was so shocked that she couldn't say a word. “You're lucky.” Annie continued. “You've still got your knee. They had to take mine.”

     “I'd like to have a chat with you, but my friends are coming any time now, so I have to get ready.” Annie said when she took off her hair! Her head was completely bald(秃头的).

     “Oh, I forgot to tell you, the medicine they gave me to kill the cancer also killed my hair.” Annie looked out her wigs(假发), brown and yellow, short and long, straight and curly.

     “That's why I thought up ‘Annie Wiggle-Do'.” Annie smiled. “Get it? Any wig will do? Annie Wiggle-Do?” “When Annie's friends came, she introduced Brenda to them all. Before long, Brenda started chatting with Annie and her friends. They didn't make her feel like a strange person at all!

    The girls shared their names with each other. When it was time to go to bed, Brenda said, “Good night, Annie-Wiggle-Do. Can't wait till morning.”

    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 famous director（导演）of a big and expensive movie planned to film a beautiful sunset（日落）over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for over. He sent his camera workers out one evening to film the sunset for him.

    The next morning he said to the men, "Have you provided me with that sunset?"

     "No, sir," the men answered. The director was angry. "Why not?" he asked.

     "Well, sir," one of the men answered, "we're on the east coast here, and the sun sets in the west. We can get you a sunrise（日出）over the sea, if necessary（必要）, but not a sunset. "

     "But I want a sunset!" the director shouted."（Go to the airport, take the next flight to the west coast, and get one."

    But then a young secretary had an idea. "Why don't you photo a sunrise," she asked, "and then play it backwards? Then it'll look like a sunset."

     "That's a very good idea!" the director said. Then he turned to the camera workers and said, "Tomorrow morning I want you to get me a beautiful sunrise over the sea."

    The camera workers went out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful coast. Then at nine o'clock they took it to the director. "Here it is, sir, "they said, and gave it to him. He was very pleased.

    They all went into the studio（工作室）. "All right, "the director explained, "now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the 'sunset' behind them. "

    The "sunset" began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera workers to stop.

    The birds in the film were flying backwards, and the waves on the sea were going away from the beach.

    One day, John read an advertisement in a newspaper. It said "Wanted. The best salesman in the world." John thought he was a great salesman and went to ask for the job. "I'm the best salesman in the world," he said to the manager. "Give me the job."

   "You must prove you're the best," the manager said.

   "OK I will," John said.

   "Good." The manager took several boxes of sweets out of his desk." Last week I bought a thousand boxes of sweets. If yon can sell them all before the end of the week, yon can have the job," said the manager.

   "That's easy," John said. He took the boxes of sweets and left the office.

    Every day and all day he went from shop to shop, trying to sell the sweets. But he couldn't sell one. The sweets were too bad for him to sell. At the end of the week he went back to the manager." I'm sorry, sir," he said," I was wrong about myself. I'm not the best salesman in the world, but I know who is."

   "Oh" said the manager. "Who?"

   "The person who sold you a thousand boxes of the sweets."
