    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. "

    As a well-known Chinese TV hostess, Dong Qing is now hosting two cultural shows, Chinese Poetry Conference and Readers. The two shows are encouraging people to love traditional culture and find the beauty of life.

    Dong was born in a highly educated family in 1973. she had a great love for traditional literature(文学)from an early age. In 2015 when she was about to study in the U.S, Dong received an invitation from the director of Chinese Poetry Conference asking her to be the hostess. Because of her passion for traditional literature, Dong accepted the job.

    "The contest interests me very much. Hosting it is a process of learning about poetry and performing, "said Dong. To her great joy, the show has become more and more popular.

    Under the slogan(口号)"Reading touches people's hearts", the new TV show Readers has become a success. It invites famous guests from all walks of life to read something. Dong works as both hostess and producer.

    Readers became a turning point in Dong's 21 years of hosting. She said it brought her "quite a huge challenge".

    "There is no shortcut(捷径) in this world. If you want to be a good host, you need to make thorough preparations, said the beautiful hostess. "The charm of life lies in its unknown, so we just have to try and keep going.

Dear Li Na,

    I'm really glad to receive your e-mail. You said you were learning to cook. Is it interesting? I think if you want to keep healthy, food is very important. You'll be better if you try all kinds of food, especially（特别是） vegetables and fruit. I eat them every day.

    You asked me how to make a milk shake. There are different kinds of milk shakes, such as apple milk shake, banana milk shake, carrot milk shake and watermelon milk shake. Apple milk shake is my favorite, because apples and milk are both good for our health. Before starting, we need an apple, a cup of milk, some ice-cream and two spoons of honey. Of course, you need a blender.

    Now, let's start. First, peel an apple and cut it up. Next, put the apple, the milk, some ice-cream and two spoons of honey into the blender. Then turn on the blender. Keep it going for only one minute. Finally, pour the apple milk shake into a glass and drink it. It's delicious!

    I want to learn how to make some Chinese food, such as dumplings, noodles and zongzi. Could you teach me?

    Write soon!

Yours,

Maria

    A poor farmer had a friend who was famous for the wonderful apple tees he grew.

    One day, his friend gave the farmer a young apple tree and told him to plant it. The farmer was glad of the gift, but he did not know where to plant it.

    He was afraid that if he planted the tree near the road, strangers(陌生人) would take the fruit. If he planted the tree in one of his fields, his neighbors would come at night and take some of the apples. If he planted the tree near his house, his children would take the fruit. Finally he planted the tree in the deep forest. But without sunlight and good soil(土壤), the tree soon died.

    Later the friend asked the farmer why he had planted the tree in such a poor place. "What' the difference?" the farmer said angrily and then told what he had thought.

    "Yes," said the friend, "but at least someone could have enjoyed the fruit. Now not only no one could enjoy the fruit, but also you have destroyed (毁掉) a good apple tree!"
