Bell was a British teacher to deaf people. He was born in Scotland in 1847 and went to school in London. Bell was interested in helping deaf people to learn to speak. He taught people how to use their mouths to make the sounds needed for talking.

    Bell's family moved to Canada in 1870 and to the USA in 1871. For several years he taught the people who could not speak in Boston. But at the same time he was developing a way to use electricity to send the sounds of talking along a wire, and he made the first telephone in June, 1875.

    The telephone developed quickly in the USA over the next few years. The Bell Telephone Company started in 1877, and in 1878 the first telephone centre was built in New York. More than 150,000 people had telephones in their homes ten years later. Bell was a kind man and spent much of his money and time during the rest of his life helping deaf people. In 1922 he died in Canada.

    July is the time for some students to say goodbye to their mother schools. Every time it comes, I will think of my old deskmate, Xiaowei. She is the most unforgettable classmate in my junior high school life. It has been many years since I graduated, but she is still in my mind clearly.

    Xiaowei was a lovely girl with long black hair. On hot days, her hair was sometimes seen to be tied up. She was always wearing a sweet smile. She was an artistic(文艺范的)girl who showed up before me every day. She loved reading novels and drawing.

    She liked reading different kinds of novels, especially on history. She could finish reading a historical novel as thick as our Chinese textbook at an amazing speed.

    Whenever she had free time, she would take out a drawing note and start drawing cartoons with a pencil. She drew from characters' heads to eyes and to faces, but the characters were always long-haired and wide-eyed. One day I couldn't help asking," Why don't you colour them?" She answered simply, "Because I don't have enough time." She kept her works as a secret and never talked about them with others. When we were told that she had won a prize in the drawing competition in her group, my classmates felt surprised.

    There is a folk song called My Old Deskmate, which is sung widely among people of different ages. It was created because the creator, Gao Xiaosong, had never forgotten his deskmate. Whenever I hear it, I will think of Xiaowei. How are you, my old deskmate?

    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."

    If you are hungry, what do you do? Have your favorite meal and stay quiet after that. Just like your stomach, your mind is also hungry. But it never lets you know. It 1 serves your needs and never lets itself grow because you keep it busy thinking about your friends or favorite stars. When mind loses 2 freedom to grow, creativity gets a full stop. This 3be the reason why we all sometimes think "What happens next?", "Why can't I think?"

     In fact, hunger of the mind 4 through wide reading. Why reading but not watching TV? It is because reading 5 the most educative tool used by us since our childhood.

    Once you read a book, you run your eyes 6 the lines and your mind tries to explain something to you. The interesting part of the book 7 is stored in your mind is regarded as a seed（种子）. Now this seed is unknowingly used by you to develop new ideas. If it is used many times, the same seed can give you great help to relate lots of things. You can never think of these things even in 8 dreams in your life.

    This is creativity. Also this helps you 9your vocabulary. In no time you can start talking with your friends in English or any other language 10you will never run out of the right words. So guys, do give food for your thoughts by reading, reading and more reading.
