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.” Who won the 2012 Nobel Prize in Medicine?

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. Like most animals, bears try to_______.

If you are not happy with China’s high Internet fees (费用) and slow speed, you are not alone. So is Premier Li Keqiang. On April 14, he said in a meeting that the government should speed up the Internet and lower the fees.
“The first question people ask at a new place is ‘Is there WI-FI’ because Internet service fees are so high,” said Premier Li. According to a recent survey by CCTV, the average cost(平均费用) of 1GB mobile Internet data per month（每月） in China is 100 Yuan, while it is only 60 Yuan in the US and 40 in Japan.
However, high prices don’t necessarily mean good service. The average Internet speed in China was 4.25Mbps（兆比特每秒）in 2014. South Korea had the fastest average Internet speed-25.3 Mbps. People can download a 1 GB movie within 6 minutes in South Koreas, but in China it would take half an hour.
To improve Internet services, the key is to build more fiber(光纤) networks. Through them we can send text, pictures and videos globally（全球地） in less than a second（秒）, which offer high speed Internet. Besides, the lack of （缺少）market competition is another problem. Having more operators（运营商）besides China Unicom and China Telecom may lower the prices. Why do people always ask for WI-FI at a new place in China?
| A．Because they can’t use Internet without WI-FI. |
| B．Because they can communicate with their families. |
| C．Because they want to download movies. |
| D．Because Internet service fees are too high. |
In 2014, ____ had the fastest average Internet speed.
| A．China | B．USA | C．Japan | D．South Korea |
What is the key to improve Internet services?
| A．To increase Internet service fees. |
| B．To build more fiber networks. |
| C．To learn from South Korea. |
| D．To make the government know the situation. |
