Global GDP in 2030 will be 14% higher as a result of AI (Artificial Intelligence), thanks to improving labor productivity and increasing consumer demand, says a report.

    The report could increase the enthusiasm of economic policymakers and the public, and show the power of technology in changing not only people's daily lives, but also economic activities. However, history tells us that, while technological advancements have brought us benefits, they have also led to great social disorders, by changing the production and labor structures, and forcing many workers to either adapt to the changes or lose their jobs. In the 18th century, for instance, skilled workers rose up to resist the Industrial Revolution, destroying machinery in the early 19th century. We may not see similar protests today, but history should serve as a warning against the application of AI technology.

    While we may gain a lot of benefits from AI, we must work out plans to reduce its negative effect on society, especially for workers. AI can raise productivity and expand GDP, but it can also make non-adaptive workers jobless. In India, some technology personnel have already felt the negative effect of information technology. As technology industries across the world seek increasing support from automation（自动操作）, robotics and big data analysis, some technology workers have already lost their jobs.

    In their 2013 research study, Michael Osborne and Carl Frey from Oxford University estimated 47% of the jobs in the United States are “at risk” of being automated in the next 20 years. They said jobs in transportation and office and administrative support are at high risk of being automated. And Kaifu Lee recently said that robots could take away about 50% of all jobs from humans in the next decade.

    Those estimates may sound sensational and the impact of technological advancements may not be that serious, as they will also create jobs in new industries. However, policymakers should consider how to better embrace the technological wave to bring benefits while taking action to minimize its negative effects. The government therefore needs to work together with business leaders and social organizations, to promote training programs for potentially helpless workers, in order to make them more capable of adapting to the structural changes in industries and job markets in the future.

    A great white shark in a California aquarium attacked two soupfin sharks(翅鲨), causing their deaths. The attack was not a natural action for food, but a kind of response when the two sharks swam too close to the great white. The great white didn't attacked other fellows, but the officials had to move other soupfin sharks to another tank(贮水池)for their safety.

    These attacks had given rise to calls for the freedom of the 88-pound, 5-foot-3- inch shark. The aquarium housed the shark in a huge tank. However, according to experts, the tank was not big enough for the shark. Its nose was bloody from striking the glass of the aquarium. Great white sharks in the wild had a big amount of migration, sometimes traveling 50 miles a day. Because the shark was still young, there was possibility of his growing. As it grows, it can became more troubled in the limited space.

    Aquarium officials said that keeping the shark in the aquarium allowed them to study their behavior that they cannot study with free great white sharks. When they studied behavioral patterns, scientists believed that they can help great white sharks in the wild.

    Since the shark had been on display, the number of people who visited aquarium increased greatly. The one-year-old shark was the longest surviving great white living here. It had been at the Monterey Bay Aquarium for six months. Other great whites did not survive for longer than 16 days in the aquarium.

    Mr. Parker was born in a small village. His father was so poor that he couldn't send him to school. The boy had to help his parents to do some farming and learned English and maths by himself when he was free. Later on he was made to leave his home village and hoped to find a job in a city. And as soon as war broke out, he joined the army. He couldn't forget his terrible past and fought with the enemies bravely. So he became a general when he was fifty. He was honest and friendly to his soldiers and often punished those who tried to pocket a portion of the soldiers' pay (克扣军饷). And his soldiers liked him very much.

    Once Mr. Parker heard from a soldier. In the letter the young man said the food in their military camp was very bad and he wished the general could go to find out the reasons, the old man went there at once, without telling anybody. He went in the kitchen and examined everything carefully and found it was very dirty. Then he went in the soldiers' bedrooms and found there were a lot of fleas. He became angry and asked the soldiers, “What do you think of your food, young men?”

    The soldiers saw their officer standing by the general and said nothing Only a new soldier said, “Very bad, sir!”

    “What did you have for lunch today?” asked Mr. Parker.

    “A fried chicken, some fish and pork, a cake, six eggs and I had three cups of wine.”

    “Really?” Mr. Parker called out in surprise. “It's the King's lunch, I think!”

    “So do I. General,” said the young man. “But it's my birthday today. I paid three hundred dollars for them all in the restaurant!”

    When someone says, “Well, I guess I'll have to go to face the music,” it does not mean he is planning to go to a concert. It is something far less pleasant, like being called in by your boss to explain why you did this or that, and why you did not do this or that. Sour music, indeed, but it has to be faced.

    The phrase “to face the music” is familiar to every American, young and old. It is at least 100 years old.

    The first information comes from the American writer James Fennimore Cooper. He said—in 1851—that the expression was first used by actors while waiting in the wings to go on stage. After they got their cue to go on, they often said, “It's time to go to face the music.” And that is exactly what they did-face the orchestra which was just below the stage.

    An actor might be frightened or nervous as he moved on to the stage in front of the audience that might be friendly or perhaps unfriendly, especially if he forgot his lines. But he had to go out. So, “to face the music” came to mean having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice.

    The other explanation comes from the army. Men had to face inspection by their leader. The soldiers worried about how well they looked. Was their equipment clean—shiny enough to pass inspection? Still, the men had to go out, and face the music of the band, as well as the inspection. What else could they do?

    While visiting the North pole in winter may not be at the top of your bucket list, the ever-changing ICEHOTEL, which opened its doors to visitors on December 14 this year, may change your mind.200 km north of the Arctic Circle in the Swedish village of Jukkasjārvi, the hotel, which is carved entirely from ice, is rebuilt annually.

    The 35 rooms, built to accommodate visitors on all kinds of budgets, vary from expensive suites to basic rooms that are furnished with just an icy bed and a reindeer skin. Among the highlights this year is the “Spruce Woods” suite. Sculpted by Christopher Pascoe and Jennie O'Keefe of Canada, it describes a camping scene complete with a classic microbus, a forest, and even an artificial campfire.

    There is also the artfully-carved “Living Ocean” suite to remind visitors of the importance of saving our oceans. The room is full of carved sea life that includes coral and a shark “swimming” right over the ice bed. “The suite is inspired by global warming and the overfishing that affects our oceans.” says artist Jonathan Paul Green. “I also think the idea of using frozen water from a river in northern Sweden to create an ocean with shells, fish, and corals is exciting.”

    The nearby “Haven” suite is a “magical gate of ice” guarded by two large animals. “We are inspired by the meeting between people and want to create an experience that invites curiosity and creativity, "says artist Jonas Johansson." It feels like a dream to get to work with ice that allows our love for light, shine, and reflection to wander freely from thought to creation.”

    Regardless of whether visitors select the carved suites or the basic ice rooms, the temperature is always set to a bone-chilling －5℃! That is why guests are advised to snuggle(蜷缩)up inside sleeping bags and wear gloves and winter hats all night. Not surprisingly, most end up spending just a single night at this unique hotel before moving on to the conventional and warmer hotels nearby.
