One night in November, Itzhak Perlman gave a concert in a theatre. If you have ever been to a Perlman concert, you know that becoming a violinist is not a small 1 for him. He had to walk 2 the help of two walking sticks as a result of the disease he caught as a child.

    People sat 3 while he made his way to his chair and began his play. But this time, something went 4. Just as he finished the first few parts of the music, one of the wrings(弦) on his violin 5. We thought that he would have to stop the concert. But he didn't. 6, he waited a moment, closed his eyes and then 7 the conductor(指挥) to begin again. The orchestra(管弦乐队) began and he played with such strong feeling and purity as they had 8 heard before.

    Of course, everyone knows that it is 9 for a violinist to play a pleasant work with just three strings. I know that, and you know that, 10 that night Itzhak Perlman didn't want to accept that.

    When he finished, there was a terrible 11 in the room. And then people rose and 12 from every corner of the theatre.

    Perlman was excited. He smiled and said, "You know, sometimes it is the artist's task to 13 how much music you can still make with what you have left."

    So, suppose our task in this fast-changing world is to make 14, at first we should try out best with all that we have. And then,    15 it is no longer possible, try to play it with what we have left.

    Today is Sunday, December 2nd, everyone in Sheep Village (羊村) is very busy. What does he/she do?

    Peter lives in a small house. He is a clerk(职员)in a bank(银行).

Peter gets up at 6:30 every morning. He has breakfast and watches TV news at 7:00. After breakfast, he goes to work by bus.

    He gets to the bank at 8:25. He gets ready to work. He has too much work to do. He has lunch in a restaurant near the bank. He finishes his work at 4:30. He likes exercise, so he goes home on foot.

    After supper, he sometimes reads newspapers. Sometimes he looks for things on the Internet. He goes to bed early. He is tired after a day's work.

    A doctor entered the hospital hurriedly after being called in for an important surgery(外科手术).He found the boy's father in the hall waiting worriedly.

    On seeing him, the father cried out, "Why did you take all this time to come？Don't you know that my son is in danger？Don't you have any sense of duty？"

    The doctor smiled and said, "I am sorry. I wasn't in the hospital and I came as fast as I could after receiving the call and now, I wish you'd calm down so that I can do my work."

     "Calm down？！What if your son was in this room right now？Would you calm down？If your own son dies while waiting for a doctor, then what will you do？"said the father angrily. The doctor smiled again and replied, "We will do our best and you should also pray for your son's healthy life."

    The surgery took some hours after which the doctor went out happily, "Thank goodness！Your son is saved！"And without waiting for the father's reply he carried on his way running by saying, "If you have any questions, ask the nurse."

     "Couldn't he wait some minutes so that I can ask about my son's state？"shouted the father when seeing the nurse minutes after the doctor left.

    The nurse answered, tears coming down her face, "His son died yesterday in a road accident. He was at the burial(葬礼)when we called him for your son's surgery. And now that he saved your son's life, he left running to finish his son's burial."

    It was the best plan ever. First, we would make sure she was out of the house. Then we would get all the work done. By the time she got back, it would be wonderful. So we got to work. How to get her out of the house? Well, we came up with a good idea. We told her that we needed some school things. She went out to get them.

    The first part of the plan was done. Next, we called aunts, uncles and Mum's friends to come to our house quickly and made sure there were no signs that they were there. We put all their shoes away. Then we cleaned the house and hung(悬挂)the balloons. The house really looked nice. Then we waited.

    When we heard her car driving up the porch(门廊), we became quiet. The moment the door opened, we shouted, "Surprise!" The look on her face was worth ten thousand dollars. Smiling and crying at the same time, she hugged all who were there. Lastly, she came to us. She said, "My best present of all is my two lovely daughters." And she hugged us happily.

    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."
