Stephen Hawking, a famous British physicist, died aged 76 on March 14th, 2018. He died peacefully at his home in Cambridge in the early hours of Wednesday, his family said.
As one of the well-known 1on space and time in the world, Hawking devoted his whole life to discovering the secrets of the Universe, and he is called the King of the Universe. However, this genius's life was not smooth and he had been 2 from the disease since he was 21 years old. When he studied maths and science at Oxford University, he became 3ill, causing his life very harsh: he could neither speak with his mouth nor stand on his legs or move his body.4, he was given only a few years to live. But he refused to 5 his hope of living and went on to study at Cambridge University after6 from Oxford University. In 1965, he got a doctor's degree in philosophy. Then he worked as a professor at Cambridge University. He was known for his work with black holes and relativity, and wrote several popular science books,7 A Brief History of Time, The Universe in a Nutshell, The Grand Design, etc.
Although he lost many most important living conditions ordinary people have, he still felt he was rich, such as a finger that could move, a brain that could think… all these made him8 to life. Last year, Hawking was invited to China. His self-confidence and humorous conversations 9us deeply.
From Stephen Hawking's10 experience, we learn that nobody should lose hope, no matter how bad the situation is. As he once said, "Life is not fair, you just have to do the best you can in your own situation."
In recent years, there have been many breakthroughs in the AI (人工智能) field. Here, let us see four of the most interesting developments in AI in 2017.

A young prince had just recently become King. In order to rule his kingdom, he decided to learn all the wisdom of world. Therefore, he gathered all the wise men from his kingdom and abroad and ordered them to look for books for him to read and learn from.
Five years passed quickly. The wise men returned with their camels, carrying 5000 books full of wisdom. Seeing so many books, the king was so shocked that he didn't know how to start. So he ordered the wise men to condense the books and bring them back to him. Another five years passed. The wise men again went to see the king, this time bringing 500 books, but the king still thought there were too many. Five more years passed. The wise men brought back 50 books. At this time, the king was troubled with many problems, but he still felt were too many books.
During the next few years, the wise men worked hard to condense the 50 books into one book and present it to the king. The king took no interest in reading this book, nor did he have time to learn from it. More problems broke out in his kingdom—his enemies endlessly attacked and diseases affected his people. He did not have the wisdom to solve these problems. Finally, the king was killed by a ruler in the neighbour country and his country was destroyed.
Waiting for wisdom to come to you is just a way of being lazy. If there is no action, there can be no gain. Only if we set out to find wisdom can we make a difference.
Four years ago, Chinese skater Wu Dajing introduced himself to the skating world by winning a silver medal at the Sochi Olympic Winter Games. At this year's Pyeong Chang Olympics, Wu not only returned, but also made history.
On Feb 22th, 2018, Wu won the gold medal in the men's short-track 500-metre race. He set a new world record with a time of 39.584 seconds. He also became the first Chinese man to take home an Olympic short-track gold medal. BBC said Wu's win was "flawless", because he was much faster than all of the other skaters.
"I didn't give them a chance and I kept my speed from the start," he told the media after the match.
But China's short-track teams didn't do well in general at the Games. Chinese skaters in the women's 500 metres, 3000-metre relay and men's 1500 metres all failed to take home the gold. Wu was China's biggest hope, which put a lot of pressure on him. But he proved himself with his great performance.
Wu is now known as a highly talented skater. But things were not always that way. When Wu joined the national team in 2010, he was seen as almost "nothing" compared to gifted skaters like Zhou Yang and Fan Kexin, as his coaches said at the time. Their comments made him quite upset. But as the saying goes, "Winners never quit and quitters never win". Wu didn't want to give up and worked as hard as he could. He practiced skating all year round. He even didn't return to his hometown for the holidays for 10 years. "I believe in myself," he told the media after his match at the Olympics.
Cold weather, central heating, and falling leaves—all these things mean that flu season has arrived. And you shouldn't take flu lightly. Flu season comes every year from October to April. This year has been especially bad, according to the US Centers for Disease Control and Prevention (美国疾病防控中心 CDC).
The flu is an illness caused by the influenza virus. It is different from the common cold in that it can strike suddenly—and it is much more serious .The flu can cause serious dehydration(脱水) and liver (肝脏)damage ,both of which can kill people.
The flu is especially dangerous for children and elderly people, since they have weaker immune (免疫) system. As of April 20, 142 children in the US had died from the flu during this flu season, according to CDC.
These deaths are not limited to the USA. In China, many people die from the flu each year as well. An elderly man in Beijing died from the flu this season, which led to a wide discussion online. The man's family didn't know how serious the flu was, just like many others who don't understand the flu very well.
What can you do to keep the flu away? Hygiene is important — take a shower every day and wash your hands often. Do not spend time around people who have the flu. And if you can, get a flu vaccine — this is a type of special medicine that can help prevent the flu. All of these things can keep you safe during flu season. If you are stick with the flu, stay home to prevent spreading it to others.
Love it or not, flying is necessary if we want to get to a faraway destination. Taking a flight in China can be a boring experience. This is because Chinese airlines didn't allow smartphones to be powered on during flights. However, the launch of a new Chinese satellite Shijian 13 has changed the situation. Now, many Chinese airlines allow passengers to use their smartphones freely, that is, we can finally catch up on our favorite books and songs while at 30000 feet in the air.
The communication satellite Shijian 13 can transmit (输送) 20 gigabytes (GB千兆) of data per second and cover most parts of China's land. This makes it the most powerful communication satellite China has ever developed. In fact, Shijian 13 has a higher message capacity (容量) than the total capacity of all China's communication satellites launched.
The powerful satellite has greatly improved the Internet, including that on fast-moving transportation vehicles such as planes and high-speed trains.
With shijian 13, people are able to get a download speed of up to 150 MBps on their smartphones. According to Zhou Zhicheng, head of the communications satellite department of the China Academy of Space Technology, the speed means it takes less than one minute to download a 1-GB movie. Watching online TV on planes and high-speed trains has come true.
But the satellite's benefits are far greater than that. China is trying to have 22 communication satellites in the sky by 2025. Shijian 13 will be able to cover wider areas, including mountains, oceans and deserts. When people have emergencies while hiking or sailing, the satellite can help them report and ask for help. It will also help people in natural disasters.
