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 Nobe 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.”

Bears are found in Asia, Africa and America. They are very strong, with short tails and thick legs. Bears eat almost everything. They seem to enjoy meat, vegetables, fruit, milk and rice.
Bears are not quite dangerous as people imagine them to be. Like most animals, they will try to stay away from human beings. However, bears are not weak animals. Sometimes they kill hunters, for they can be very dangerous.
Bears have a good sense of smell but they have poor eyesight. They are also hard of hearing but they are very clever. They feed mainly on roots, frogs, fish and also small insects. They will sometimes kill deer and other large animals, but they seem to like small animals better.
In the cold area, bears hibernate, or go to sleep from October to April. Before they start to hibernate, they eat a lot and store fat. The mother bear has its babies, usually two, towards the end of hibernation. A large bear is much cleverer than a cat and most other animals. You may notice at the zoo how cleverly they ask for food. They sit up and hold out their paws. You would have to teach a dog such a trick but the bears learn this by themselves.
