    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.

    This is' a story of a man who worked in a big factory. I got to know him many years ago, but I never paid any attention to him. He always wore an old red hat and carried a rubbish bag. He usually spent his break time and lunchtime walking around in that old big factory to collect the unused tins.

    Today, I was fixing one machine in the factory when this "tin man" came with his bag. As usual, he picked up the tins. My manager was standing there to watch me. He asked the "tin man" what he was going to do with those tins. I never thought about this question, because I always thought that he'd sell those tins for money.

    The "tin man" answered, "I will give these tins to my neighbour. He is ill and he cannot work." I was so surprised to hear that, so I asked him, "You collect all those tins just to help your neighbour? I know this does not help much," he said. "But I will try my best to help him."

    At that time, I found myself standing in front of a great man. This "tin man" only wore a T shirt and an old red hat and carried a rubbish bag, but he was a great man.

    We shouldn't judge a man by his appearance(外表). We should look at his heart.

    It was the last day of the final examination in a college. On the steps of a building, a group of engineering students were waiting for the last exam. On their faces was confidence.

    They knew the exam would be easy. The professor had said they could bring any books or notes during the test.

    Right after they came into the classroom, the professor handed out the papers. There were only five questions on it.

    Three hours passed. Then the professor began to collect the papers.  The students no longer looked confident. On their faces was nervous expression. The professor watched the worried faces before him, and then asked, "How many of you have completed(完成) all five questions?" No hand was raised. "How many of you have answered four?" Still no hands.  "Three? Two?" The students moved restlessly in their seats. "One, then? Certainly somebody has finished one. "But the class kept silent. The professor said, "That is exactly what I expected. I just want to make you know clearly that even though you have completed four years of engineering, there are still many things about the subject you don't know. These questions you could not answer are common in everyday practice. "Then, smiling, he added, "You will all pass this course, your education has just begun."

    The years have obscured the name of this professor, but not the lesson he taught.
