A

    Several months after I was badly hurt in a car accident, my father sent me to a blind school.

    That morning was the new beginning. I went to this school and I heard lots of children. My new teacher took me to the class where we were taught to write and type in Braille(盲文 ). I found it quite difficult.

    "Hi, sweetheart, how is school going?" asked my father.

    "Daddy, I can't do this. I try and try but I just don't get it. I don't know if I am ever going to learn to read Braille. It's too difficult," I cried.

    Daddy just held me in his arm and said, "Do you remember that we went to the temple which is on the top of a mountain? When we were climbing the mountain, my legs started aching. I sat down and said, 'I can't see the temple. You can't see it because it is covered with fog. Although you can't see it, I know it is here. I will make sure you will climb up to it.'"

    "That day you showed me that just you can't see something does not mean it is not there. So although climbing the mountain was difficult, I knew I would get to the top."

    I was clear what my dad wanted me to understand.

    I went back to school and started with new energy. Very soon I could read.

One of my classmates said, "You are lucky, you know, you have at least seen the world. I have just heard it. I have been told there are many colors in this world but I don't understand what color means."

    After listening to her for the first time in two years, I felt lucky. And on that day I learnt that although the light in my eyes is gone. I must see the world with the light in my heart.

    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. However , 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 the 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. "

    There is an old tiger in the forest. He doesn't want to look for food now. He often asks other animals to get him something to eat.

    One day, he sees a monkey and says, "I am hungry, monkey. Go to the village and get me something to eat. "

    "I can't do that now, tiger," the monkey says, "There is another tiger over there. He will not let me get anything for you to eat. I am afraid of him. "

    "What?" cries the old tiger. "Take me to that tiger. I will talk to him."

    The monkey and the tiger get to the bridge over the river. "Now look down at the water." says the monkey. "Do you see the tiger?"

    "Yes, I do," cries the old tiger. "I will eat him."

    With these words, the tiger jumps into the river.

    Peter lived in a village. He was sad recently because he thought that he had nothing left. One day, Peter went to ask a wise man for help. He said to the wise man, "I have nothing left, so I don't want to live." The wise man smiled sympathetically(同情地).

    The wise man took out a piece of paper and drew a straight line down the middle. He explained that he would write down the things Peter had lost on the left side and the things Peter still had on the right side.

    The wise man asked, "When did your family leave you?"

    "What do you mean? They haven't left me. They love me!"

    "That's great!" said the wise man. "Then that will be the first thing on the right side -Family haven't left. Now, do you have freedom(自由)?"

    "That's a silly question. Of course I do!"

    "Good! That's the second one on the right side-You have freedom!" said the wise man, writing it down.

    After Peter was asked some more questions in the same way, he finally understood and smiled. "Things will change when you think of them in a different way!" he said.

    As a matter of fact, change your attitude and you will change your world. It's necessary to have a positive(积极的)attitude to life.
