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. "

The secret of happiness

    An old man walked slowly with a cane(手杖)into the restaurant .His old jacket, worn-out shoes and warm personality made him stand out from the usual crowd.

    A young waitress watched him move toward a table by the window. She ran over to him, and said: “Here, sir……let me help you with that chair.”

    Without saying a word, he smiled and nodded(点头)a thank you. She pulled the chair away from the table and helped him sit. Then she put his came against the table.

    “Thank you, miss.”he said, kindly.

    “You're welcome, sir.”she said.

    After he had finished his breakfast, the waitress brought him the change(零钱)from his bill. He left it on the table. She helped him up and walked with him to the front door.

    When she went to clean his table, she found a business card under his plate and note on a napkin(纸巾). Under the napkin was a 100-dollar bill.

    The note on the napkin read: “Dear miss, I respect you very much and I can see you respect yourself, too. It shows by the way you treat others. (3)You have found the secret of happiness. Your kindness will shine through to all those who meet you.”

    The man she had waited on was the owner of the restaurant where she worked. This was the first time that she or any of the other workers had ever seen him in person.

    On a rainy day, about 150 volunteers worked for eight hours to clean up Carson Creek that is near a river. About nine tons of trash was taken out from there.

    “We did a good job,” said Alan Specter, the organizer of the event. “We're planning to come back here one more time, three years from now. Of course, we hope that there won't be so much trash next time.”

    The trash came in all shapes, sizes, and colors: cans, bottles, bicycles, batteries, furniture, clothing, plastic bags, dolls, and even a golf bag with a full set of golf clubs (球棒).

    The dirty and tiring work was done by two volunteering groups — Save the Bay and Watch the Whales. Most of the volunteers came from a local police station and a fire station. And some of them were old people who had already retired (退休).

    That day, it rained a little. All of them wore boots, gloves and raincoats. They did the work along a two-mile river with over 500 big yellow trash bags everywhere.

    No one found anything that cost much. A five-year-old boy found an earring which he thought might be worth a million dollars. He said he'd sell it. Then he'd donate half of the money to Watch the Whales, and use the other half to buy his favorite ice cream every day.

    Many people laughed at the boy's story. However, it was easily found that the environment there did become better.

    Like many high school graduates, Maggie Doyne didn't go straight to college. She decided to travel and arrived in western Nepal in 2006. A war had just ended there and left many children living on the streets. They were often forced to work at hard physical jobs for little money.

One day, while walking down a country road, Doyne saw a little girl breaking up rocks. She soon learned that 7-year-old Hima sold the rocks to support her family. With deep sadness, she decided to pay Hima's tuition(学费) for school. Encouraged by the changes in the child, Doyne thought, "If we can help one child, why not 10？"

    Doyne felt that the street children's greatest need was a home. She found a piece of land for sale and bought it with $5,000 she saved from years of babysitting (当临时保姆). In 2008 the Kopila Valley Children's Home was set up. With the help from the community, another goal was reached in 2010—the Kopila Valley School. Over 350 children now attend the school and over 50 live in the home.

    Today, Doyne lives in the home and is "mum" to the kids.

    Is handwriting (书写) important? Yes, the 10-year-old girl Alyssa thinks so. She is a fifth-grade student from Mason County, the USA. She's the champion (冠军) for her grade level in the National Handwriting Contest in 2012.

    After she got the news, Alyssa was surprised that she could be the first. "I'm really happy," she said. "I'm really surprised, too. I didn't know I was that good."

    To enter (参加) the contest, each student had to write the sentence (句子) "The quick brown fox jumps over the lazy dog". It is a common English sentence, but it uses every letter of the English alphabet. Teachers were invited to be judges. They could decide who wins the contest.

    Alyssa enjoys handwriting, and wants to write adventure (冒险) stories when she gets older. "From the third grade we started learning handwriting," Alyssa said. "All the letters look pretty. It makes me think of art."
