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 finished 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(坚持不懈) can lead.

At the age of 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, 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(克隆) of the adult frog. This technique later helped to create Dolly the sheep 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. "

    Jane is only four years o1d and she doesn't go to school. But she is very clever and learns a lot from her grandpa—an old teacher. One day, Jane's mother, Mrs John takes her to a party. The guests（客人）all praise（表扬）a rich woman's son. Mrs John asks him a few questions, but his answers are wrong. Jane begins to laugh.

    The rich woman is angry.  She te11s her friend—a teacher to ask Jane some questions, but the little girl answers all. Then she asks, "There are three birds in a tree. How many will be left（被留下）if I kill（杀死）one?”

    “One” answers Jane. “You're wrong!” calls out the rich woman. “All of them will fly away”,“Do you think a dead（死的）bird can fly?”asks the little girl.

    The guests begin to 1augh and the woman's face turns red.

    Fiona likes to listen to music. She likes to listen to classical music. Now she is listening to Beethoven's Symphony (交响曲) No. 5. The music is about fate knocking on the door. Fate is the unseen power of life. Fate changes our lives. Fate designs our lives. Fiona likes this music. She feels the power of music.

    Suddenly, somebody knocks on her door. She goes to the door and opens it. There is a man at the door. The man is old. He has grey hair and a grey beard (胡须). She doesn't know who the person is. The man says he is her father. She closes the door in front of the man. She stays at the door and thinks. She has a father. But he is dead. She doesn't know the man at the door. She doesn't understand why he says he is her father. She wants to call the police. Just then she can see a photo under the door. The man is giving her a photo. She looks at the photo. She can see herself with a man she doesn't know. It is her because she took many photos when she was a young girl. Is the man who is standing in front of her door her father? She must find the answer.

    She opens the door. She asks the man whether he is lying or not. The man tells her he is telling the truth. She invites him for a cup of coffee. They sit down and drink coffee. They start talking about life. He tells her everything that he knows. She listens. Sometimes she is surprised. Sometimes she cries. Sometimes she laughs. They are listening to Beethoven. This time it is not fate, but her father who is knocking on the door.

    Jan Mela was born in Poland and he lost an arm and a leg in an accident in 2002. But that didn't stop him. The 15-year-old boy from Poland walked to the North Pole(北极) in 2004.

     "If I can do it, other people can do great things, too," Mela said before he went. Polish newspaper said Mela was the youngest person and the first disable(残疾) person to walk to the North Pole. Mela walked to the North Pole with the help of a man-made leg.

    After the accident, Mala felt sad for himself. But he didn't lose hope. One day, he met Marek Kaminski. In 1996, Kaminski went to the North Pole and the South Pole in the same year. Mela wanted to see the North Pole, too. So Mela asked Kaminski if they could go together the next time. Kaminski said yes.

    It took Mela twenty-one days to get to the North Pole. The last three or four days were really hard because of the bad weather. But Mela didn't give up going.

A difficult thing I met

I've always loved the radio.1 I was a child, I had a dream to be a presenter at a radio station or a TV station.I started to present shows for the school radio station at the age of ten.And I always expect to visit a radio or a TV station someday.

Yesterday my teacher took us to visit a radio station, I couldn't help being 2 . I 3 early in the morning and took a bus to the radio station with my classmates.We were so lucky that one director was4 and he showed us around the studio.We saw the programme that was on air in it.We had a chance to 5 a presenter and we were very happy.

 We knew that in order to 6 making mistakes, the presenter would practise what he would say many times.It seemed that he knew 7 everything about the national and international background and information.He knew what the listeners wanted very well.He would read the articles written by the part﹣time reporters many times 8 . He must know the 9 of the articles, and then got ready for the programme well.So everything is not easy to do. If we want to do 10 well, we must work hard, keep on practicing and get ready for it all the time.
