Mr. Turner liked fishing. It was his favorite sport. He often fished for hours without catching anything. But this did not worry him. Some fishermen couldn't catch fish. Sometimes they caught old boots or rubbish. Mr. Turner was even worse than the fishermen. He never caught anything - not even old boots. After he spent whole morning on the river, he always went home with an empty bag. "You must give up fishing!" his friends said, "It's a waste of time."  "But they don't realize one important thing. I'm not really interested in fishing. I am only interested in sitting in a boat and doing nothing at all. It can make me forget the noise of the city and live quietly for some time." he always said to himself.

    Mandy Harvey is a 29-year-old singer from Florida. She lost most of her ability to hear when she was 18.

    Harvey became a singer in her teens. _________ But she decided to start singing after she learned how to feel a song's beat through the wooden floor of a stage or theater. She watches carefully to make sure her musical instruments are tuned correctly and she is singing in the correct pitch.

    Harvey is now a professional singer. But not many people in the United States had heard of her until Tuesday night. That changed when she appeared on the television show “America's Got Talent”The show has four judges who watch people perform and decide if they should continue in the competition.

    Harvey said, "I gave up singing after I lost my hearing. But I want to do more with my life than just give up." As she was singing, one camera cut away to capture images of people in the theater. Many were seen crying. At one point, everyone stood up and cheered. By Wednesday afternoon, a video of Harvey's performance had been played 46 million times.

    Why? Shortly after she finished singing, Simon Cowell, one of the judges, gave her a golden star into the air. That meant Harvey could move on to the final round of the talent competition. Cowell said," I've done this a long time, and that was one of the most amazing things I've ever seen and heard."

    Many people wrote online that Harvey's performance was encouraging, and they will not give up on anything they want to do, either.

    John, David and James were three brothers. Every year on their mother's birthday, they sent her expensive presents. They liked to show her how rich they were.

    The oldest brother , John, decided to give his mother a perfect(完 美的) present. He thought it must be more expensive than his brothers'.

    So he put an advertisement(广告) in the newspapers: WANTED THE PERFECT PRESENT FOR A RICH WOMAN. For many days people phoned him from all over the country. Each of them wanted to sell him" the perfect present". But John didn't like any of them.

    Then, less than a week before his mother's birthday, a man came to his office. He was carrying a cage with a large bird in it. "This bird," the man said," can speak ten languages (语言) and sing any popular songs. There's no other bird like it in the world." With these words, he asked the bird to speak to John in French, tell him a joke in Japanese and sing a famous popular song. John was very happy.

    "I'll buy it. How much do you want?" John said." One hundred thousand dollars," the man said. This was a lot of money, but John paid him. Then he sent the bird to his mother with a birthday card.

    The day after his mother's birthday he phoned her." Well, Mother," he asked," what do you think of the bird?" "Oh, very delicious, dear," she answered.

    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 Sixth Time I Went to the Principal's Office When I was in the seventh grade, I had problems behaving. My heart was in the right place, but I couldn't always follow the rules. I played many tricks on my schoolmates. Once, I even pulled a girl's hair on the school bus to get her attention. As a result, I was repeatedly sent to the office of the principal(校长).

    Although I hated going there, I did not hate the principal, Mr. Ratcliff. Mr. Ratcliff was a kind, elderly man. When he spanked(打屁股)me for putting some ants into a classmate's pencil box, it didn't hurt at all, but it did hurt my feelings. I thought so much of him and moments like that seemed to prove I was hopelessly bad.

    When I got called to Mr. Ratcliff's office for the sixth time, I had no idea what I had done. I felt disappointed as I walked down there. I went into his office, sat down, and looked at the floor. Then he said the last thing I expected to hear:"

    Kevin, I've heard you've been behaving really well lately. I want you to know how proud I am of you, and I just called you down to my office to give you a peppermint."

    "Really?" I was surprised.

    "Yes. Now you can take that peppermint and go back to class."

    I carried the peppermint with me as if it was a gold coin. When I got into my classroom, I bragged(吹嘘)to my classmates about my turnaround, excitedly. I wasn't so bad after all.

    Mr. Ratcliff was really kind. He made me realize that I was just a kid who had problems with behavior. He bought some peppermints and took the time to notice me when I got something-anything-right. Mr. Ratcliff gave me some hope by giving me some love. I will just remember him for the rest of my life.
